An interview with Iolo Williams

Iolo Williams was born and brought up in mid Wales. After gaining an ecology degree he worked for the RSPB for almost 15 years as Species Officer for Wales. In the late 1990s Iolo left the Society to work full-time in the media, presenting in both Welsh and English. He co-presented Springwatch 2020 and is a tireless campaigner for wildlife and conservation.

We caught up with Iolo and asked him a few questions on: lockdown, rewilding, Brexit and the future for nature.

Wales has a variety of landscapes and environments; do you have a favourite habitat?

I was born and brought up in mid-Wales and grew up in a small village called Llanwddyn (Lake Vyrnwy), which was a fantastic area with a mixture of habitats. But, where I am happiest really is up on the high ground: up on the mountains, up on the moorland, enjoying not just the solitude and the scenery, but some of the amazing wildlife, such as: black grouse, merlin and hen harrier. You have also got sundews, butterworts, and bog asphodel; all amazing and well adapted to these harsh conditions. So that’s where I’m happiest really – when I want a day by myself, away from everyone, that’s where I head for.

Do you think ecotourism and nature capital have a role to play in wildlife conservation?

I think ecotourism is absolutely vital for the future survival of our wildlife and our habitats, and ourselves too. It’s only when we educate people, it’s only when people see what’s out there, it’s only then that people grow to appreciate it and will then fight to ensure that it survives for their children and for future generations. So, I do believe it’s a vital part of conservation and education.

But of course ecotourism does involve travel, which is a dilemma. I travel a lot less than I used to and off-set it as much as I can, but I learned a lesson whilst visiting Chitwan National Park in Nepal and lamenting my carbon footprint involved to get there. The head ranger heard me and said, ‘Listen, if you didn’t come here, there wouldn’t be a national park. The government wants the wood, wants to log these trees you see here. It wants to drain this wetland to grow cash crops. But it’s only because of the money you bring in that we are able to protect and enhance this national park: the Indian one-horned rhino, the Asiatic elephant, the tigers and all the other wildlife that’s here.’ So, it is a dilemma, but to stop that overnight would be disastrous for wildlife worldwide.
The pros, do out-weigh the cons – as long as we are sensible about it; we need to stop needless travel, we need to utilise public transport wherever we can, and in a rural area like mid Wales it’s often not even possible – more often than not I have to take the car. A change must come from individuals, but more than anything the change has got to come from government – we need a better public transport system.
Ecotourism can also provide sustainable jobs. I’ve just come back from Mull; the eagles bring in a huge amount of capital every year. Mull would probably grind to a halt without ecotourism. Yes, you have agriculture there and farming, but by far the biggest employer in Mull is green tourism. People come to Mull to see eagles, to see otters, to see minke whales, basking sharks, and all of these charismatic species. Morally, we shouldn’t have to put the economic argument forward, we should be looking after wildlife for its own sake. But when you are dealing with developers and ministers, you have to put the economic argument forward.

Are you a supporter of rewilding and do you think it is a sustainable use of land?

I am in principle, but say ‘rewilding’ to a lot of people and they say, “ah, they’re going to bring back wolves and bears, and I don’t want wolves and bears. My children will be mauled” etc. While that’s not true it’s also not true that’s what rewilding is all about. It’s really about the restoration of habitats, it is about what Isabella Tree and her husband have done at Knepp, which works fantastically well. Places like the Cambrian Mountains have fantastic wildlife like pine martens, goshawks, red squirrels etc, but vast areas of the Cambrian Mountains are a green desert. So, the potential for rewilding; just a few trees, maybe restoring the lost peat bogs etc. is vast and the knock-on effects for capturing carbon and preventing flooding all makes so much sense. But of course, the people in power want to make more money for themselves and their acquaintances and a lot of them don’t want to consider embracing this approach.

Does Brexit and the end of the Common Agricultural Policy (CAP) present any opportunities?

Firstly, I voted against Brexit, I think it will be an unmitigated disaster. It was the tabloid papers stirring the pot of xenophobia that prevented the real issues being properly discussed. Most of the farmers around me here voted for Brexit because they were fed up with what they saw as European bureaucracy. Of course, now the reality is biting, many farmers I speak to now wish they hadn’t, especially now as their MP has voted to allow cheap, low standard foods from the US into the country. Despite what we sometimes read, the food standards in the UK are very high and to lower those standards is stabbing farmers in the back.

However, in the long-term Brexit can offer an opportunity. If we had a better government in power, I would be optimistic about those opportunities because there is no doubt the CAP has been a most destructive policy from an environmental point of view. It really should have been reformed at least twenty years ago and now is an opportunity to do that, but with the current government’s track record with the environment makes me believe not much will change. We are up against a very powerful agricultural lobby. The big fertiliser companies, the big pesticide companies, the big machinery companies all of these are a massively powerful lobby and this government will listen to their argument not the environmentalist’s.

Has lockdown presented people with an opportunity to connect with nature?

I hear people saying how wildlife benefitted hugely from lockdown, and I think temporarily it did. One simple example is far fewer hedgehogs killed on the roads, of course now lockdown is eased I’m seeing dead hedgehogs on the roads all over again. Also, roadside verges not being mown or mowed late had a knock-on effect that was huge!! Flowers, bees, butterflies all in abundance. Some councils have seen this, taken note, and said – okay fantastic, we are going to reduce mowing from now-on. Others have carried on mowing and mowing, which is an absolutely dreadful policy for wildlife. Lockdown has really tested people, especially from a mental health point of view, but during lockdown the birds, flowers and butterflies have brought so much joy to families. Nature has been there for us through this traumatic time and we must remember that when these restrictions are over.

The one long term benefit I’m hoping lockdown will have is that a seed has been planted in a lot of youngsters and adults where they will think: remember last year when we walked this lane and there was all those flowers and we saw that lovely white and orange butterfly, let’s go and see if it’s all there again. So, hopefully for many people that seed has been planted.

A Field Guide to the Birds of Malaysia & Singapore: an interview with the authors.

This comprehensive, clearly illustrated field guide, looks at all 815 bird species of Malaysia and Singapore. The main identifying features of each species are described and key facts cover size, voice, range and status and habitat. Distribution maps provide a view of where the birds can be found. The book also includes information on taxonomy and nomenclature, the breeding cycle, migration, conservation and key bird-watching sites of the region. This guide is essential for any naturalist interested in this region of the world.

Recording and observing such a rich diversity of birds, with over 800 species of birds including endemics in abundance is a huge undertaking. How does such a daunting project come to fruition? We asked contributors: Lim Kim Seng, Yong Ding Li and Lim Kim Chuah to answer some questions about themselves and the creation of A Field Guide to the Birds of Malaysia & Singapore

Can you tell us a little bit about your backgrounds within ornithology and conservation?

Kim Seng – I started birding when I was about ten years old. I grew up in a family farm in Sembawang, in the northern countryside of Singapore. Together with my four other brothers, we explored the streams, hills and swamps and grew to love nature. One day, I saw a large kingfisher with a brown head, bright red beak and blue wings. It was my first Stork-billed Kingfisher and I was hooked. I was able to identify it through a book that I found in our National Library Natural History Section. Five years on, I joined the then Malayan Nature Society (now Nature Society (Singapore)) as a student member and just four years later, I led my first official society birdwatching outing at Rifle Range Road, together with my other birding brother Kim Chuah. With the help of other dedicated members, I learned a lot and was able to play my part in nature conservation, documentation, research and outreach, and have been an active member since then.

Ding Li – I have been birdwatching since my primary school days, after finding what I later discovered, to be Magpie Robins near my home in Kuala Lumpur. Subsequent visits to the mangroves of Kuala Selangor introduced me to the colourful world of birdwatching. Through various research projects, I have professionally studied birds in diverse settings ranging from Malaysian rainforests and the mountain forests of Sulawesi (Indonesia), to Australian woodlands. I now work full-time for BirdLife International, coordinating projects on bird conservation in Southeast Asia.

Kim Chuah – I grew up in a farm in rural Singapore in the ’60s and the surrounding woodlands and marshes were my playground. During my many sojourns into the wilderness, I started to notice some of the birds that lived around me – White-breasted Waterhen, Yellow-vented Bulbul, Common Tailorbird etc. That’s how I became interested in birds and it became my life-long passion. I’ve been volunteering in the Bird Group of the Nature Society (Singapore) since I was an undergrad. I participated in many of the birdwatching activities organized by the Bird Group including regular bird census and bird surveys. The data we collect helps towards a better understanding of birdlife in Singapore and is useful in building our case for better protection of habitats in Singapore.

How long has this project been in the making?

Kim Seng – My friend Dana Gardner, the illustrator of this book, got me interested in doing another book. We had successfully collaborated on a first field guide to the birds of Singapore in 1997 and were keen to work together again. Dana had a friend who was a publisher and we decided to a do a single volume field guide to the birds of the whole of Malaysia, since none existed. This was in 2010. Unfortunately, our publisher pulled out not long after that and we were left stranded. Luckily, through my fellow collaborators – Kim Chuah and Ding Li – we managed to get John Beaufoy interested in our project. A contract was signed in 2016 and as they say, the rest is history!

What was the biggest challenge in creating this field guide?

Kim Seng – Each of us had different ideas on how to do the book and also other personal commitments. We as the writers also had to contend with differences in writing styles. Luckily, we decided to stick with a standard format, came up with a list of who was writing what chapters and what bird families and managed to more or less stick to our deadlines. Another challenge was the impressive work done by our illustrator. He had to do illustrations of all 829 species all by himself. To ensure accuracy, he would send us completed plates for comment, and we duly responded if changes were needed. Not an easy task, as we were based in Singapore and he, in the USA.

What features do you hope will make your field guide stand out from any others?

Kim Seng – This book is compact and contains all the necessary information you need to identify any bird species you see in the listed countries. The text is crisp and the illustrations accurate and there is also a detailed site and habitat guide to get birders to the most interesting places quickly and see those fascinating birds, based on the authors’ many years in the field.

Have the travel restriction due to COVID – 19 presented any threats or opportunities for the avifauna of Malaysia and Singapore?

Kim Seng – Well, COVID-19 has placed tremendous restrictions on travel in both Malaysia and Singapore. You could bird in certain areas but only with social distancing and other safe practices in place. Initially, we could only look at the birds from our balconies or backyards but this was an opportunity for some of us to study some of the neglected urban birds and understand a little better. I actually published two blogs based on my observations of urban birds from my balcony! In the last couple of months, restrictions have been eased and we are allowed to go birding in our favourite birding places, but I’m still waiting for the day when I can travel freely and bird in Malaysia again.

Do you think eco-tourism is beneficial to conservation?

Kim Seng – Definitely. I believe ecotourism brings a lot of attention to the tremendous beauty and biodiversity of the natural habitats in both countries. It also brings revenue and employment opportunities to the local community who in turn will help to protect these wonderful places for a long time to come.

What in your view are the best reasons to visit Malaysia and Singapore if you are a birdwatcher or an ornithologist?

Kim Seng – Three reasons – good birds, good food and good company. All three are never in short supply in these two amazingly friendly countries. The people are generally very friendly and the variety of local food is really incredible. Of course, the fascinating diversity of birds, with over 800 species of birds and Bornean, Peninsular and Sunda endemics in abundance are dreams to savour for birdwatchers and ornithologists alike.

Are you working on any other projects you can tell us about?

Kim Seng – I am currently working at putting up an adult learner’s module or course on “Birdwatching for Beginners”. It’s something I had worked on in the past and I want to continue my work in getting people of all ages interested in birdwatching as I believe it is a healthy and useful pastime. It should be fun as there are outdoor trips as well.

Ding Li – I am currently working with a team of designers to develop a board game on the migratory bird species of Asia. Such a concept to promote bird conservation has not been done in this region, so I am quite excited to see the final project materialise. I am also working with a team of international researchers to review the state of all of Asia’s migratory birds. If all goes well, this will be published in early 2021, and will bring together lots of new insights from all over the region and how migratory birds can be better conserved.

Kim Chuah – I am currently organising the 36th Singapore Bird Race. It will be interesting to see how we can organise the race during this pandemic. We will use the social media and available digital tools to make the race as exciting as in previous years. I am also working on action plans to better protect and conserve the critically endangered Straw-headed Bulbul in Singapore.

Author Interview with Benedict Macdonald and Nicholas Gates: Orchard: A Year in England’s Eden

The orchard has been a traditional component of the British landscape for many centuries. However, subsidies have led to the destruction of older traditional orchards to make way for more intensive farming and now only a fraction remain.

The value of these orchards for wildlife has long been underestimated. Ben Macdonald and Nick Gates spent years visiting a traditional orchard across all seasons observing its imperilled and overlooked abundance of life.

Ben and Nick have taken time to answer our questions about their book and this remarkably fertile habitat.

Could you tell us a little about your backgrounds?

Nick Gates (NG): I grew up in West Sussex, and could usually be found building a dam across a stream or out catching grasshoppers and slow worms on the Ashdown Forest somewhere. I ended up reading Natural Sciences at Cambridge and, similar to Ben, have now found myself making wildlife documentaries. But I adore spending time in the field, and am forever looking for new areas to explore, new behaviours to interpret and new species to learn about.

Benedict Macdonald (BM): I grew up north of Bristol, and my fascination with nature began with raising butterflies at school, which then took me onto my great passion for birds. I took a different route to Nick, studying English at Oxford to improve my journalistic skills before moving into the natural history film industry. The love of birds remains – and it was indeed the search for breeding lesser-spotted woodpeckers for the BTO’s Bird Atlas that, one magical morning, led me to the Orchard.

Where did the motivation for this book come from? Are Orchards a subject that you have been wanting to write about for some time?

NG: The project actually started as a photographic record, nest-box project and field diary. We certainly didn’t envisage when first visiting the orchard that one day we’d be able to convert our passion for it into a book. As the years went by, and we uncovered more of the orchard’s stories each season, we realised we had built up a library of magical stories about this special place – and the book idea was born.

You divided the book into chapters by each month; was this something you planned all along and why did month-by-month fit the narrative of the orchard so well?

BM: As any pair of naturalists will tell you, the skills you have are similar but often complimentary. In January, for example, much of the expertise lies in tracking small mammals around the orchard, and reading prints etched in the snow – one of Nick’s favourite past-times. May is all about birdsong and concealed nests, and spoke deeply to my own love of birds. But make no mistake – every month is special in the orchard. The players are always on the move.

NG: Having spent six years visiting the orchard across all seasons, it was clear that its stories were deeply rooted around the lifecycles of the apple and perry pear trees – which themselves have a very defined year. Once the book idea became a reality, it seemed the most natural way to introduce our audience to the orchard world. As Ben and I both often travel abroad on our respective filming trips, it also worked really well when dividing the chapter structure, as we each had unique experiences from certain months that we wanted to share.

The neighbouring orchard is run intensively and very differently to the orchard you studied; what would you say are the practical advantages of being less intensive?

NG: The major benefit appears to be maintenance. Spraying an orchard many times a season requires expensive inputs in machinery, as well as the manual labour required to continually prune each tree to a very defined shape to make the spraying as efficient as possible. In an unsprayed orchard, many different age classes of trees can thrive alongside each other. If an elderly tree is lost to a storm, it is easy to leave some of the deadwood and replace it nearby with a new young specimen. But the biggest benefit is that with an intact food chain, your costly pesticide inputs are replaced with spotted flycatchers and redstarts, which arrive for free each year and willingly hoover up all manner of insects that enjoy nibbling fruit trees!

BM: The summer migrants are critical to the success of the orchard – but the residents play an invaluable role. Throughout the winter, various species of tits, finches and woodpeckers, especially lesser-spotted, are all rooting out potentially harmful insects from the bark of the orchard’s trees. And as Nick puts it, treecreepers act as tree ‘dentists’, removing lots of tiny insects that could eventually end up reducing the lifespan of the trees.

The orchard you observed rewarded you with plenty of surprising stories and scenarios. Was there one single episode that stood out for you?

BM: For me, it was when we finally solved the mystery of the goshawk’s larder. Our generation has grown up with the idea that goshawks are limited to big woods and often those dark, silent plantations. The idea a goshawk could be hunting our orchard didn’t even occur to us at first, even after we found pheasant after pheasant neatly plucked. It was only when the pair decided to display right overhead one March that, like an Agatha Christie novel, it all came together.

NG: I have been out in the field looking for interesting stories in the natural world for as long as I can remember, so it is always rewarding coming across something unexpected. The best thing about the orchard, is that this just seems to happen so regularly! But if I had to single out one, I’d say my biggest surprise was the day I excitedly returned to photograph the coal tit family nesting in a pear tree, only to find the entrance to their nest firmly blocked with a rather unfortunate wood mouse. Having most likely scoffed the nest contents, it couldn’t fit back through the hole it had entered through. It was one of the most extraordinarily bizarre things I’ve yet chanced upon in the natural world.

Do you think a separation from the EU’s Common Agricultural Policy (CAP) can create any opportunities for wildlife and biodiversity?

NG: Yes. The CAP model has ample opportunity for reform, and I hope that this is reflected in whatever system is adopted post Brexit. A model that rewards land owners for improving the biodiversity on their land is long overdue, as is a system that recognises carbon capture. There are certainly massive opportunities for British biodiversity – it is now up to those in positions of decision making to ensure they chose the correct advisers to inform these new policies.

BM: The Common Agricultural Policy has paid for enormous destruction of the countryside, and even models such as orchards that should be profitable to farmers – not just wildlife. In my view, we actually need a specific orchard subsidy. It seems mad that we can continue to pay for sheep grazing to denude hillsides and accelerate the flow of water off the hills, yet we cannot pay our farmers to grow apples. But this subsidy has to happen soon: orchards are vanishing fast.

Installing a wildlife pond is often sited as being the best way to add biodiversity to a garden; for those lucky enough to have the space, would you recommend planting an orchard for a similar reason?

NG: Absolutely. With something like a pond, you tend to see the rewards within just a few months of installing it, as the first newts and dragonflies arrive to breed in the new water source. Whilst fruit trees can take a few years to start blossoming and become increasingly valuable for your local wildlife, they mature incredibly quickly relative to most other tree species. Apples and pears are usually producing blossom and a crop in five to seven years, and by 40 years of age are well on their way to becoming an ‘ancient orchard’. Also, fruit trees, particularly those grafted to dwarf rootstock, don’t actually need a lot of room – and considering it only takes half a dozen trees to be called an orchard – most public green spaces could host a small wildlife orchard that would be of great help to local biodiversity.

After a well-earned rest, are there any plans or works-in-progress that you can tell us about?

NG: Ben and I have a few ideas for co-authored projects in the future but our next respective titles will both be individually written. I am currently working on a book about an urban wildlife garden…watch this space!

BM: As I approach the end of writing my third book, Cornerstones – for Bloomsbury (published January 2022), I have to be honest that a writing break is in order. Both writing and publicity are fantastic to be involved in but they do take a lot of time. Perhaps I can put my feet up and read Nick’s wildlife gardening book!

Woodland Wildlife: Managing Woodlands for Biodiversity

In 2018 , while still running a taxi business, an opportunity arose to purchase a few acres of local woodland on the edge of Dartmoor in Devon. Completed within a matter of weeks, Steve and Tamara Davey became proud custodians of their very own woodland!

When they discovered an impressive range of wildlife on their woodland site, they decided that the management of the area would be based on the continued provision of habitat for certain species, including seven recorded bat species, the visiting Nightjar and Woodcock.

We caught up with Steve to ask him about how they are supporting nature through their project Woodland Wildlife.

Can you tell me a little about your backgrounds.

Both Tamara and myself had childhood holidays in the Scottish Highlands as children, and there is no better place to develop an affinity with nature. It’s a place that holds a permanent residency within our hearts, those childhood memories imprinted on our futures. Mine were on the West Coast of Scotland opposite the Isle Of Skye. We used to stay in these old caravans that leaked and were powered by calor gas. The smell of the matches and gas appliances echoes those memories for me. The area was only a few miles up the coast from where Gavin Maxwell wrote his best-selling book Ring of Bright Water. As a family we spent a lot of time down at Sandaig ( in the book it was Camusfearna), Gavin’s books were really the only ones I read due to my interest in nature and love for Scotland. Above his hearth he had inscribed in Latin the words “non fatuum huc persecutus ignem” meaning, “it is no will o the wisp that I have followed here.” This phrase is very apt and resonates with our Woodland Wildlife project.

Aside from Scotland both Tamara’s and my childhoods involved getting out in nature with family walks, especially on Dartmoor. Also, similar to the book and film Kes, aged twelve I had a female kestrel to look after. My father converted the garden shed, and I remember rushing home from school every day. We looked after a tawny owl for a while too. Myself and our son also volunteered at a local bird of prey centre – these memories, and the knowledge you gain from an early age all lie dormant until the right opportunity presents itself later in life.

What motivated you to embark on the Woodland Wildlife project?

From the Spring of 2018 we made regular trips to the woodland because we couldn’t keep away and used to come up with loads of excuses to the selling agent on why we were visiting so often. We completed the purchase at the end of the summer. During the first twelve months we were staggered by the volume and diversity of the wildlife within our little plot and it was this that spurred us into creating Woodland Wildlife. I couldn’t believe that the domain woodlandwildlife.co.uk was available so I snapped it up. I then asked the web company that had recently rebuilt my taxi website to work on a website for Woodland Wildlife. They came up with the current logo which I really liked however the squirrel was grey and so I asked them to change it to red as that signified hope to me! At that point the future focus was more on the development of guided visits. In August last year we set up the Facebook page and that is seeing a steady increase of followers. We post on there most days and this time of year we may be posting up to eight times in one day, purely because of the observations – we are always finding new species to photograph. Through the winter months the posts are more project focused as that is the time of the year when most of the manual work is done.

Coppiced sweet chestnut protected from surrounding deer damage

Felled young sitka used as dead hedging around boundary line

What has been the biggest challenge in returning the woodland back to nature?

The nature was already there, nothing has needed returning as far as we are aware. But with small sized plots sensitive management is vital, for instance; if you don’t manage that important grassy ride, over time succession will take hold and that habitat (in our case) would be overrun with bramble and bracken, therefore the grasses would die off and displacement of species will happen. Our grassy rides are alive with insect life and as far as we are concerned these areas are a priority within our plot. When you see how small an area our grassy rides are and you see how many species they are supporting such as: leaf hoppers, beetles, bees, hoverflies, moths, grasshoppers, crickets, butterflies you can then understand how vitally important these small areas are. I would say our biggest challenge is still ahead of us. In 2012 the main plot was clear felled and in 2013 the holding company planted over 2000 young sitka spruce trees. These are now over eight years old and growing rapidly in amongst the birch, sweet chestnut, beech and a few other species. Being on an easterly facing slope (after all it is Devon) we are giving careful consideration to future extraction of timber and to what extent the damage would be. We are mindful not to ruin everything that we have done over the years. so the plan will be (in conjunction with the Forestry Commission) to convert over to native woodland. We will still retain some sitka for the goldcrests and siskins, but these will be in the area towards the top of the plot, whereby future extraction damage will be minimal.

Sitka are awful trees to work on as they are very prickly to handle. Even though they are only young it’s incredibly hard work felling them and dragging them around to produce dead hedging. Our adjoining plot is a mature stand of Douglas fir of 3.5 acres and that has recently been thinned. The remaining stems will grow on for a further 5 to 10 years, with the extra light they will grow in girth and not height. We have tagged a random 30 stems and will monitor their growth rate annually. This is one commercial aspect to our project, we plan to nurture a healthy self seeded understory within this stand and re plant where necessary in the future when it’s felled.

Was there a particular plant or animal that you wished to see return to the woodland?

Yes, the nightjar, they are in the area this season which is great, last summer they were on our plot and we regularly saw two of them. Having your own woodland is one thing but having nightjar in your woodland is a priceless dream. We spent many summer evenings there watching them, calling them in with a recording of their call (yes that works). On a couple of occasions early in the nightjar season, June I think, they landed in front of us on a tubex shelter, attracted to anything white due to the males having white markings on their wing and tails. Our sleepy dogs got their attention and flew in to check us out. The video is on the website, it’s not brilliant as it was recorded on my phone, but a wonderful experience nonetheless. We observed them through to the end of July and on each occasion the sightings consisted of a brief checking us out and churring away like they do. A truly amazing bird that due to its nocturnal habits has not been an easy species to study. They like young plantations up to approximately ten years of age as after that the canopy has closed in. They also like birch and sweet chestnut, both of which we have in abundance. We are coppicing the sweet chestnut which will give a more diverse structure to the woodland and also has many benefits to other wildlife as well as giving longevity to the tree itself. The nightjars arrive in May and have normally disappeared by the end of August and sometimes into September. Once the young have fledged they will migrate. Our thinning works of the Douglas fir overran into May and we are certain that that level of disturbance (the sound and vibration of over 200 mature fir being felled) made them look elsewhere for a suitable nest site for this season. High hopes for next year!

In what ways can you draw an income from the project and how do you ensure that those ways are sustainable?

Part of the plot is mature Douglas fir, so over the years there will be an income from the felling of those but there also comes obligation and costs to re-plant. This area is 3.5 acres and we are hoping that at least 20% of that area will self-seed and will therefore not need re-planting. After 14 years of running a taxi company we have decided to pass it on to someone else as we want to concentrate on our woodland which will also involve craft sales. We plan to sell at an occasional local market, selling wooden products such as pendants, necklaces, key rings, hand made cards, Christmas decorations and fairy houses. All of the wood used will be from the bi product of our habitat work and therefore very sustainable. We are not skilled wood turners, I would describe our woody crafts as rustic. We also hope to offer guided visits for small groups of people who either want to immerse themselves into an incredibly diverse 8 acre plot of woodland that doesn’t have any public access( that’s called forest bathing nowadays), or groups and individuals that would like to visit to look at our management practises, it could also be for specialist groups to study bats, birds, butterflies etc. Although the craft sales will be necessary we do hope that the tours can be a success too as we will have great pleasure in sharing this unique place in South Devon.

Woodland Wildlife crafts to be sold on-site or at craft markets

Sustainable felling and logging of Douglas fir

What would you say has been the project’s biggest success story so far?

This has to be the three small wildlife ponds created in the spring of last year. Our philosophy has always been that our work creates a biodiversity gain. The ponds are a totally new feature to the wood and therefore a totally new habitat with the nearest water course being in the bottom of the valley.
The ponds are host to pond skaters, diving beetles, water boatmen, frogs, toads and a few species of dragonfly. The mosquito larvae they produce is a food source for the seven recorded species of bats that we have there. The frogspawn and toadspawn this year was amazing. This is boosting the sites biodiversity and that feels great. The Devon Wildlife Trust’s, Batworks Grant, helped with the costs of the ponds which was very welcome indeed, because so far we have funded all the costs ourselves. The top pond was also designed with a very shallow gradient at one end so that any feeding nightjar can swoop in and get a drink on the wing.

The other success is our plantings, since Nov 2018 we have planted over 400 additional trees, shrubs and hedging. From scots pine to broad leaved privet, all-in-all over 20 new species have been planted. The hedging area consists of field maple, hazel, dog rose, dog wood, crab apple, blackthorn and hawthorn, and is growing well, albeit slowly. Once mature this will provide an incredible food source and habitat for many species. We also sought advice from a consultant ecologist on behalf of Butterfly Conservation, they recommended planting broad leaved privet, wild privet and alder buckthorn all of which will provide a valuable food source for many species of butterflies, insects and moths. The alder buckthorn being the food plant for the brimstone butterfly caterpillar.

Can you offer any advice to anybody wanting to undertake a similar project?

There is a misconception that when you purchase some woodland in the UK that you are legally bound to manage your plot, but this is not the case. Currently you can do as much or as little as you want, there are legalities regarding volume of timber that you are allowed to cut down, and rightly so. Personally speaking I think there should be some sort of stewardship course involved with any woodland purchase, but generally speaking people who buy woodland do have the environments best interests at heart. Neither myself nor Tamara are formally qualified in land management or woodland management, but what we do have in bucket loads is the passion, and when it is your passion you absorb information like a sponge. If you are interested in purchasing some woodland please make sure you do a lot of reading up first, SWOG ( small woodland owners group) is a great resource. Think about things like how far are you willing to travel to get to your woodland, our journey takes 25 minutes but I know of some owners who live a couple of hours away and then that restricts those little journeys when you just want to go there for an hour or two. Think about public access and rights of way, access, species of trees on site, how neglected the woodland is because that may dictate how much physical work maybe required. I know owners that have a couple of acres of plantation and therefore their management work is negligible. Think about orientation, diversity and age of species and the potential value of the timber there. Getting a flat site is not easy and virtually impossible in Devon, some come with streams etc. You would need to appoint a solicitor as the conveyancing is similar to house buying but much more straight forward.

We would say to anyone interested in purchasing some woodland to definitely do it, it is an amazing thing to do, yes we can buy fancy cars and gadgets and go on expensive holidays but owning your own little piece of nature is a priceless thing to do. It’s more like guardianship than ownership, but you will have a lot of control over the future of that plot.
Love nature, it will never fail you.

Do you have any long-term plans for the future of Woodland Wildlife?

Well where do we start here? If money was no object we would like to deer fence large parts of our woodland to allow natural regeneration to occur unhindered. But money is an object so we will improvise and mitigate the grazing as much as possible. Luckily we are not overrun with roe deer but there are a few around. The damage they do to new growth is staggering.
Over time we would like to see part of our main plot restored back to its natural former state which was wooded heath. Around 1800 the wider woodland was mapped as a Down which would correspond with our small patches of heather and large amounts of gorse and bracken. Dry lowland heathland is a scarce habitat these days and we would like to re-nature that habitat along with keeping the coppiced sweet chestnut, birch and beech. The plan will be for the main plot to remain an open woodland with pockets of heath and grassy rides. We will keep some sitka on the higher parts of the plot.
This winter will involve widening the lower part of the North to South ride which is quite overgrown, creating a ride that will traverse the contours from the West to East ride. This will involve the felling of a lot more young sitka but it will kick start the project of connecting up some of our micro habitats. We are keen to provide a suitable site for the migrating nightjar and the wintering woodcock and this will involve a lot of physical work. Any major works such as this needs careful consideration for the future resilience of the woodland. All of our plantings have been carefully selected with the future in mind for example, the scots pine (although slow growing) is a fantastic tree that supports a large amount of wildlife plus once established will cope well with periods of dry weather. We have also planted some juniper and these trees will also cope admirably in dryer conditions and therefore the challenges of climate change. The naturalised species such as birch, beech, gorse, heather, bramble and bracken will naturally cope with dryer summers.

With regards to Woodland Wildlife as a business, we hope that the occasional small group or individual will continue to visit to experience this magnificent site. We aim to continue with the craft sales into the future. We aim to continue to document our species and our works. The emphasis will be on small groups as we are keen to prevent compaction of soils.

Woodland Flowers: an interview with Keith J Kirby

Woodland Flowers: Colourful Past, Uncertain Future is the eighth instalment of the popular British Wildlife Collection. In this insightful and original account, Keith Kirby explores the woodland plants of Britain living in the shade of their bigger relatives. They add so much to woodland’s biodiversity and beauty and tell us stories about the history of woodland, its past management, and how that has changed – not always for the better.

Author, Keith Kirby has taken the time to sign limited copies of Woodland Flower and has answered our questions about the book, and the flowers that enhance our woodlands.

Could you tell us a little about your background?

I grew up in a village in Essex and spent much of my childhood playing in the fields, along the riverbank and in small woods behind our house. I was interested in natural history but not really a serious naturalist. Sometime in my teens I decided I wanted to be a forester and ended up doing a degree in Agricultural and Forest Sciences in Oxford. That introduced me to ‘ecology’ and led to a doctoral study of the growth of brambles in Wytham Woods. From there I spent a couple of years doing woodland and general habitat surveys before getting a permanent post in 1979 with the Nature Conservancy Council as a woodland ecologist. I stayed in that post (NCC became English Nature, became Natural England) through to 2012, then retired back to Oxford and picked up my plant research interests in Wytham Woods again.

Where did the motivation for this book come from? Are woodland flowers a subject that you have been wanting to write about for some time?

Much of my work with NCC and its successor bodies involved considering the woodland ground flora: we used them as one indicator of the value of sites, as guides to what was changing in terms of woodland management and the woodland environment more generally; some species such as bramble and bracken could also be a problem when we were trying to get regeneration. There was not then the time to pull the different strands together, so when I was back in Oxford I thought I should give it a go.

Have you noticed any unusual changes within woodland flora this Spring following the lockdown? Has it helped or hindered?

I would not really expect to see a direct effect of lockdown on the plants: often their growth is determined by reserves laid down the previous year and a few months is not very long when you consider that many woodland plants – not just the trees – can live for several decades. There could be indirect effects, for example if less disturbance in woods means that deer produce more fawns, so more hungry mouths to nibble away at the flora in future.

Germander Speedwell, a species that spreads quite quickly into new hedges.

Although adaptable, woodlands are clearly not invincible. What do you think is the greatest threat to woodland ecosystems?

In the longer-term (25-50 yrs) climate change. The micro-climate at ground level in a wood has not changed as much as out in the open because of the sheltering effect of the tree layer, but it will do eventually and this will lead to a re-assortment of which species can thrive in different parts of the country.
In the medium term (10-25 years) I suspect that we are going to see more and more evidence of change from the build-up of nitrogen in forest soils from the emissions from cars, modern farming etc. I am picking up signs that this is happening in Wytham.
The immediate threat – and it affects our ability to deal with the medium and longer-term issues as well – comes from the impact of high numbers of deer in the countryside. They limit tree regeneration and make woodland management more difficult as well having direct effects on the ground flora species themselves. At Wytham we saw during the eighties and nineties a complete shift from a flora of herbs and bramble to grass-dominated cover. That is being reversed – we are fortunate in being able to manage the deer population there – but in many other woods deer numbers are too high. This means for example that it will be difficult to get the regeneration of species such as oak, beech or hazel that will be needed over the next few years to fill the gaps in the canopy left as Ash Dieback progresses.

What single policy change would you like to see to help counter this threat?

Through history trees and woods (and hence the woodland flora) have survived best where they are valued by society: so we need to encourage greater use of wood as a material in buildings, as fuel, as a feedstock for industry; as well as promoting woodland as places for recreation, to help with water management, for carbon sequestration, and as a source of inspiration.

The tricky question of ‘nativeness’ – Oxlip outcompeted by dense Pendulous Sedge patches.

As you note in the book, there’s currently a lot of interest in rewilding. What role do you think rewilding can play in the future of UK woodlands?

From the answer to the previous question it will be obvious that I want to see a lot of woods being managed to provide the materials that society needs; moreover many of our woodland plants can thrive under such conditions – if management is done carefully – as they have done for centuries. Rewilding though also has a great role to play in future conservation alongside actively managed woods (as long as we can get away from the endless debates about the meaning of the term itself). Rewilding leads to different types of woodland structures and composition, a different set of dynamics in the landscape, some of which may be analogous to what may have existed 6,000 years ago, but other combinations will be completely new. New mixtures of woodland plants (and animals) will come to be associated with rewilded treescapes that will also be a response to the changed environmental conditions. Exactly what will emerge unpredictable and there will be interesting challenges ahead for land managers, regulators and conservation advisers – we are not in the UK going to be able to be completely ‘hands-off’ even in the wildest of rewilding.
Rewilding is however one of the reasons why I am cautiously optimistic we can yet pass on a reasonable legacy of woodland flowers.

Now that the book is finished, and after a well-earned rest, are there any plans or works-in-progress that you can tell us about?

My first priority has been to try to catch up on writing-up the results from long-term studies of the flora in Wytham Woods and The Warburg Reserve near Henley. Also once the country has opened up a bit more after Covid-19 I plan to spend time to spend some more time with the wood beneath the trees; so I have been drawing up a list of woods across the country that I want to go and visit again.

Editor Interview: Tim Burt, Curious About Nature

Curious About Nature provides a passionate voice in support of fieldwork and its role in ecological research. Comprising a series of chapters written by forty diverse contributors, this inspiring book hopes to encourage both new and seasoned ecologists to pursue outdoor learning and research as often and fully as possible.

Tim Burt (who edited the book alongside Des Thompson), recently took the time to answer some of our questions.

Firstly, could you tell us a little bit about your backgrounds and how you came to be collaborating on this book.

We have both been involved with the Field Studies Council since 2006 when Des joined the Board of Trustees (I have been a trustee since 1982), but we had worked together before then, for example, a conference on the future of the British uplands held in Durham in 1999.

What are your first memories of fieldwork?

As I note in my essay in Curious about Nature, I came under the spell of an inspirational teacher at secondary school, Jim Hanwell. My first memory of fieldwork is being sent to measure the width of the main road outside the school gate to compare with the width of the red line printed on the OS map. Not something that would be done these days given health and safety concerns, but nevertheless I was hooked! Jim’s main influence was in physical geography, geomorphology especially, with many field trips to the Mendips and even an expedition to Spain and Portugal.

Some of the most well-known and respected scientists in history have had an incredibly varied range of interests and passions. Take Darwin, for example, who not only studied plants and animals, but also geology, anthropology, taxidermy and medicine. Do you think that, in modern times, we no longer celebrate or respect the ‘generally curious’ and instead expect people to be much more specialist in their areas of expertise?

Specialist research is inevitable in these very competitive days; departments compete via research assessment rankings and individuals must build their CVs to gain promotion. But in my experience, the best academics retain a breadth of interest; in physical geography this invariably combines fieldwork with other skills back at the department.

You currently hold the positions of President (Tim) and Chairman (Des) of the Field Studies Council and, as such, must both feel passionate about the education of field skills. With increases in health and safety concerns alongside reduced funding for outdoor activities, have you observed a change in child and youth education over the past decades in terms of the amount of fieldwork that takes place?

Health and safety concerns can (and must) be sorted out; it is continued funding that puts field trips at risk. The value of outdoor education is important for all sorts of reasons, not just academic knowledge and understanding. There is a real threat at the moment, with next year’s focus on getting schoolchildren back in the classroom. Senior administrators must be convinced of the value of investing in fieldwork, otherwise it is an easy cost to cut. But at what eventual “cost”?

At NHBS we sell a lot of equipment that is purposely designed to limit the amount of time that researchers and naturalists have to spend in the field – such as motion-activated trail cameras. While these are the preferred choice for many researchers, do you think that there benefits to traditional, observational fieldwork that cannot be replicated by collecting data remotely?

Field equipment has always been necessary, even in the days of clockwork mechanisms and pen-and-ink chart recorders. Today’s digital equipment expands the possibilities, not limits them. But it is still vital to be out in the field, curious about what is happening and what you can see – this is how new ideas are generated. There is no substitute for standing on a hillside, thinking about the landscape in front of you, especially if you happen to be somewhere very different to England like the badlands of southern Utah!

Do you have a favourite fieldwork pioneer (included in the book or not) whose story you find particularly inspiring?

People always think of Charles Darwin as a biologist, but he was equally a geologist on the Beagle, and his geological observations during his circumnavigation of the globe remain fascinating to read, for example, his thoughts about the formation of coral reefs and atolls. He was very much a follower of Charles Lyell in his appreciation of the dynamic nature of the Earth’s surface.

Finally – what are you each working on currently? And do you have plans for further books?

We do have plans for a further book together, an elaboration of Curious about Nature, with a working title In the footsteps of Gilbert White. For my part, I have been drafting chapters for Durham weather and climate since 1841, to be published by OUP. Last year I co-authored a book (with Stephen Burt, no relation) about the weather records at the Radcliffe Observatory in Oxford, so the new book is complementary to that, with much the same structure, but clearly a different regional focus. I ran the Oxford weather station for 10 years and have been in charge of the Durham station since 2000.

Curious About Nature is edited by Tim Burt and Des Thompson and is published by Cambridge University Press. It is available from nhbs.com in paperback and hardback.

Author Interview: Andrew G. Duff, Beetles of Britain and Ireland Vol 3

In our latest Q&A we talk to Andrew Duff, keen naturalist and author of the new book Beetles of Britain and Ireland Volume 3, which joins a monumental 4-volume identification guide to to the adult Coleoptera of the Republic of Ireland, the United Kingdom of Great Britain & Northern Ireland, and the British Crown Dependency of the Isle of Man. By bringing together reliable modern keys and using the latest taxonomic arrangement and nomenclature, it is hoped that budding coleopterists will more quickly learn how to identify beetles and gain added confidence in their identifications.

Andrew has taken his time to answer our questions about his book and about the fascinating world of beetles.

Aside from the most conspicuous species, beetles seldom seem to attract as much attention as some other insect orders. What is it that has drawn you to study this group?

My initial attraction to beetles was by coming across some of the larger and more colourful species, as you might expect. The first occasion was in about the late 1970s. I was out birdwatching with my oldest and best friend, the Ruislip naturalist Mike Grigson, when he found a species of dor beetle. These are large black beetles, often found wandering in the open on heaths and moors. They have the most striking metallic blue undersides. Picking one up, Mike said to me: “beetles are really beautiful ”, and I can still picture him saying it. The next occasion was when I was assistant warden at the Asham Wood reserve on the Mendip Hills in Somerset, in the summer of 1982. The warden, Jim Kemp, was an expert mycologist with a side interest in beetles. One day we were on the reserve and he pointed out a black-and-yellow longhorn beetle sat on an umbel. I thought it was very exotic-looking, every bit as worthy of a naturalist’s attention as butterflies and orchids! So I resolved to find out more about the beetles found in Asham Wood. Bristol Reference Library had a copy of Norman Joy’s Practical Handbook of British Beetles and it was obvious that I needed to buy it. Once I had my own copy of ‘Joy’, there was no stopping me. I started finding beetles and was able to identify most of them. The more you study beetles, the more you realise that all of them have their own special kind of beauty, and this is what ultimately led me to become a coleopterist. That, and the intellectual challenge of identifying small brown beetles, are what continue to inspire me.

What motivated you to write and publish Beetles of Britain and Ireland?

Joy’s Practical Handbook of British Beetles was the standard beetle identification guide for at least two generations of British coleopterists, ever since its publication in 1932. Joy’s book provided concise keys to every British beetle in a handy two-volume set, one volume of text and one of line drawings. The trouble with this idea is that the keys were oversimplified and misleading because of all the detail that wasn’t included. By the 1980s ‘Joy’ was already long past its ‘best before date’. Talk started about somebody producing a successor set of volumes and the late Peter Skidmore made a start—after his death I was fortunate to obtain his draft keys and drawings, and in particular have made much use of his drawings in my book. Peter Hodge and Richard Jones then published New British Beetles: species not in Joy’s practical handbook (BENHS, 1995). This was a fantastic achievement because it brought together in one place a list of the species not included in ‘Joy’, as well as notice of recent changes in nomenclature and of some errors in his keys. But it was still only a stop-gap measure.

By around 2008 still nothing had been produced by anyone else. I reckoned it might be achievable and began to discuss with other coleopterists the idea of writing a new series of volumes. The turning point was a discussion with Mark Telfer at a BENHS Annual Exhibition in London. My main concern was over the use of previously published drawings in scientific papers, but Mark reassured me that provided the drawings were properly credited and that the book was clearly an original work in its text and design then it should not fall foul of any copyright issues. By 2010 I’d already made a start on Beetles of Britain and Ireland and in the summer of that year took early retirement so that I could work on it more or less full time. My own professional background is as a technical author in the world of IT and from the 1980s onwards I’d had extensive experience of what used to be grandly called desktop publishing, what we would now call simply word processing! I’d decided to go down the self-publishing route so that I could ensure the production values matched what I thought coleopterists would want: a book which was laid out clearly and would stand up to a lot of wear. It’s really for others to judge whether my volumes meet the needs and expectations of most coleopterists, but so far I’ve been pleasantly surprised at how well they’ve been received.

How did production of this book compare to the previous volumes in the series? Was it difficult to bring together information on so many families exhibiting such a diversity of life histories?

As this is the third volume to have been completed I’d already learnt a lot about the best way to collate all of the material and summarise it, while trying to make as few mistakes as possible. The previous two volumes (vols. 1 and 4) were written in a rather erratic fashion, so that at any one time some sections would be more or less complete while others would not even have been started. This time I was determined to be more disciplined by starting with the first family, completing a draft which included the family introduction, keys to genera and species, and all of the line art illustrations, before going on the next family and doing the same again. In a way, having many families was an advantage because it meant I could use a ‘divide-and-rule’ strategy by breaking down a fauna of 1088 species into 69 smaller chunks. The fact that there are so many families in this volume didn’t generate any special problems, indeed families with only a few species like the stag beetles, glow-worms and net-winged beetles are relatively straightforward to document. But some of the family introductions were a challenge, insofar as some families are poorly defined taxonomically and hard to characterise in a way which would be accessible to amateur coleopterists. For example the darkling beetles (Tenebrionidae) exhibit a bewildering diversity which makes it well nigh impossible to say why a particular species is or is not assigned to this family. I made extensive use of the two-volume American Beetles (Arnett et al., 2002), which contains succinct summaries of nearly all of our beetle families, and this made my job a lot easier. But at the end of the day, the family diagnoses are not as important as the keys to genera and species. Most coleopterists won’t be coming to a particular family chapter as a result of methodically working through the key to families in volume 1. I imagine that in most cases people start by comparing their beetle with the colour plates, getting a shrewd idea as to what family it belongs to, and then going straight to the keys to genera and species. Picture-matching will always have its place in natural history, and I hope that Udo Schmidt’s 473 colour photos in this volume will be put to good use.

This volume covers some of our most familiar beetles – the ladybirds and chafers, for example. What advice would you give to anyone seeking to extend their interest beyond these well-known families to the more ‘obscure’ groups?

I would say that it largely depends on what kind of naturalist you are. What I mean by this is that there are two main ways of studying beetles, and you have to decide which path is right for you. On the one hand, many naturalists take photographs of beetles and by using the Internet or an expert validation service such as iRecord (www.brc.ac.uk/irecord/) they can usually achieve reliable identifications, at least to genus level, for medium-sized and large beetles. Some spectacular finds of beetles new to Britain have been found by general naturalists posting their images on the Internet, a very recent example being the flower-visiting chafer Valgus hemipterus, first posted to iRecord in April 2019 and already given the full works treatment in my volume 3. The problems start as soon as you try to identify smaller and more obscure beetles, because most of them are simply not identifiable from photographs. It’s not their small size and lack of bright colour patterns as such, so much as the need to view the underside, or the fore legs from a particular angle, or the head from the front, or the body orthogonally from directly above to ascertain the precise shape, which makes field photography impractical as a way to identify small beetles. So what you need to do is to go down the second path and start a beetle collection. This enables you to examine your specimen with a bright light source under a good stereomicroscope, turn it over to examine the underside, stretch out its legs to look for the pattern of teeth and spines, straighten it to measure its length and width, and if you’re feeling brave dissect out the genitalia which often provide the only definitive way to arrive at a species identification. Many naturalists balk at the thought of collecting beetles, but I would argue that the scientific value of having a comprehensive species list for a site outweighs any squeamishness I might feel about taking an insect’s life. In any case, my guilt is assuaged by the fact that insects are being eaten in their trillions every day, everywhere, by all manner of insectivorous animals and plants, so that the additional negative effect of my collection on beetle populations is vanishingly small.

Could you tell us a little about the process of compiling keys for the identification of the more challenging species? Were you able to draw upon the existing literature, or did you have to create them from scratch?

Some of the genera treated in this volume have been giving problems for coleopterists ever since the scientific study of beetles began. These are genera with a number of very similar, small and plain species that appear to have few distinguishing features. Nine genera in particular stand out for me as being conventionally ‘difficult’: Contacyphon, Dryops, Cryptophagus, Atomaria, Epuraea, Carpophilus, Meligethes, Corticaria and Mordellistena. It was always going to be a challenge for me to provide workable keys to these ‘nightmare nine’ genera, but I was keen to give it a go. It helps that I take a perverse interest in very difficult identification challenges, so I was motivated to come up with keys which would work. Fortunately I was able to pull together information from a variety of different sources until I had draft keys which could be put out for testing. The testing went through a number of iterations and by reworking the keys—for example adding my own illustrations, simplfying or reorganising couplets, or adding new couplets to account for ambiguous characters—they were gradually improved until I was happy with them. A second source of difficulty concerned the aphodiine group of dung beetles. The formerly very specious genus Aphodius was recently broken up into 27 smaller genera, and our leading dung beetle expert, Darren Mann, recommended to me that we should adopt the new taxonomy. This meant that I needed to construct a completely new key to genera, and that took a great deal of time and effort searching for characters. Incidentally I’d like to pay special thanks to Steve Lane and Mark Telfer for their advice and help with these difficult genera; I owe them both a great deal for their encouragement and support. The keys to challenging genera in this volume will certainly not be the last word on the subject, but I believe they are an improvement on previous keys.

When gathering information on habitat and biology of the various families, did you notice any glaring omissions? Are there any families that could particularly benefit from further study?

Some of the families treated in this volume are well understood, in terms of their identification, ecology and distribution in Britain and Ireland. The scarab beetle family-group, jewel beetles, click beetle family-group, glow-worms, soldier beetles, ladybirds, oil beetles and cardinal beetles are all popular groups and have been reasonably well studied, while the ladybirds have received a huge amount of attention! But that accounts for just 13 of the 69 families treated in volume 3, and the remaining 56 families are in general much less well known. Modern identification keys in English already existed for some of the other families but for most the information is very basic. I would say that the biggest gap in our understanding concerns the synanthropic and stored-product beetles. Not only do amateur coleopterists rarely come across these species, but the information that has been gathered (mostly by food hygiene inspectors) has not been made publicly available. In a few cases it’s not even clear which country a species has been found in, and all we know is that it has been found at some time, somewhere in Britain. I would like to think that this group will one day be much better documented.

A particular favourite of mine are the silken fungus beetles (Cryptophagidae). This family contains two of the ‘nightmare nine’ genera: Cryptophagus with 35 species and Atomaria with 44 species. I’ve tried hard to produce workable new keys for these two genera, but their identification is never going to be easy and it will be necessary to validate records for a long time to come. But I hope that at least this family will begin to benefit from a greater level of interest, on the back of my new keys.

There will be one more volume to come before this monumental series is complete – are you able to provide an estimation as to when that will come to fruition?

Volume 2 covers just one huge family: the rove beetles (Staphylinidae). This has been left until last for two good reasons. Firstly, the subfamily Aleocharinae, and in particular the hundreds of species in the tribe Athetini, are so poorly understood that it’s just not clear where the generic limits are drawn. This means I will have my work cut out trying to construct a new key to Aleocharinae genera. Preferably the key won’t involve dissecting out the mouthparts and examining them under a compound microscope, as we are expected to do now! Secondly, it has to be admitted that rove beetles are not the most exciting to look at. As publisher as well as lead author of my series of volumes it was always going to be difficult to sell a book which didn’t contain a lot of colourful plates. My plan all along, then, was to leave the rove beetles until last, in the hope that people would buy the book in order to complete their set! Volume 2 has already been started, and Udo has been working hard on the colour plates, but there is still a mountain to climb to complete the Athetini keys and illustrations to my satisfaction. My best estimate currently is that it will be published no later than 2024. Once that is done, and if I still have my wits about me, I suppose I’ll have to think about revised editions of the earlier volumes!

Palace of Palms: Tropical Dreams and the Making of Kew: an Interview With Kate Teltscher

Daringly innovative when it opened in 1848, the Palm House in Kew Gardens remains one of the most beautiful glass buildings in the world today

In Palace of Palms, Kate Teltscher tells the extraordinary story of its creation and of the Victorians’ obsession with the palms that filled it: a story of breathtaking ambition and scientific discovery and, crucially, of the remarkable men whose vision it was.

Cultural historian and author, Kate Teltscher kindly took some time to answer our questions about her new book.

Can you tell us something about your background and what motivated you to write Palace of Palms?

I’ve visited Kew since my childhood and have always loved the Palm House. It’s such a magnificent building, and just astounds you, the moment that you enter the Gardens. It’s so sleek and elegant, and modern-looking. As soon as you push open the door, the heat hits you, and you’re inside this tropical world. The architecture and plants combine to form this astonishing spectacle. The whole Gardens are landscaped around the Palm House, and the three long vistas at the back mean that you’re always catching sight of the Palm House as you walk the grounds. I wanted to find out why the Palm House was at the centre of Kew. Why was it the first building to be commissioned when Kew became a public institution? As a cultural historian, I was interested in the story that the Palm House could tell about Britain and botany, about palms and empire. And then in the course of my research I became fascinated by the characters that I discovered: the ambitious first Director, the self-taught engineer, and the surly yet devoted Curator.

The historical period in your book has been described as ‘The Golden Age of Botany.’ Do you think this description is justified?

The period certainly saw the birth of modern botany and many plant collecting expeditions, but the idea of a ‘golden age’ seems outdated now. The phrase tends to obscure or gild botany’s connection with commerce and empire. From its very foundation as a public garden, Kew had close links with colonial gardens across the empire. John Lindley, the botanist who wrote a government report on Kew, proposed that the colonies would offer up their natural resources to Britain to aid ‘the mother country in every thing that is useful in the vegetable kingdom’. Kew was seen as the co-ordinating hub of a network of colonial gardens in India, Australia, the Indian Ocean and the West Indies, that would exchange information and plants across the globe. Transplanting medicinal plants, economic and food crops across continents, Kew engineered environmental and social change worldwide.

Why were palms so important to the Victorians?

The Victorians inherited the great Swedish botanist Carl Linnaeus’ notion that palms were the ‘princes of the vegetable kingdom’. They were regarded as the noblest of all plants, far surpassing all European vegetation. For the public educator, Charles Knight, they combined ‘the highest imaginable beauty with the utmost imaginable utility’. They provided every necessity of life: food, drink, oil, clothes, shelter, weapons, tools and books. They were so bountiful that Linnaeus imagined that early humanity had subsisted entirely on palms. As Chambers’s Edinburgh Journal put it: the question is not ‘What do they afford us? But what is there that they do not?’

Your book is full of intrigue, exploration and innovation. During your research was there one fact or event that stood out as been particularly remarkable?

I was particularly struck by the change in status of palm oil between the 1840s and today. Industrial chemists had recently discovered the properties of palm oil that would, in our own time, make it one of the most ubiquitous of vegetable oils. In the nineteenth century, palm oil was used as axle grease on the railways and, combined with coconut oil, as a constituent of soap and candles. The oil palm grew in the areas of West Africa previously dominated by the slave trade. The trade in palm oil, it was argued, was the most effective means to combat human trafficking. In contrast to current fears that palm oil production is a major cause of deforestation and involves child and forced labour, the Victorians viewed palm oil as an ethical product, with unlimited manufacturing possibilities.

How do you envisage the future of the Palm House, the finest surviving Victorian glass and iron building in the world?

I understand from Aimée Felton, the architect who compiled a report on the Palm House, that despite the constant humidity of the interior, the actual structure is in reasonably good shape. These days, I guess, the Palm House does not look so big. Some of the tallest palms can never reach maturity because the Palm House roof is not high enough; they have to be cut down so that they don’t break through the glass. Obviously modern plant houses, like the Eden Project biospheres or the Norman Foster-designed Great Glass House at the National Botanic Garden of Wales may be larger or wider. But what I find interesting is that these plant houses, like the Palm House, are daring, experimental structures. The Palm House really functioned as the model for glasshouses across the globe throughout the nineteenth century: in Copenhagen, Adelaide, Brussels, San Francisco, Vienna and New York. From a contemporary point of view, the Palm House is often seen as a forerunner of twentieth-century modernism. It offers a perfect union of form and function, with its clean lines and organic shape. In recent years, the Palm House has provided the inspiration for one of London’s current icons: the London Eye. I expect that it will go on inspiring architects and engineers for years to come!

Are you working on any new projects you can tell us about?

I’m hoping to work more with Kew, in particular a project to digitise an early record book that documents all the plants that were received and sent out from Kew at the end of the eighteenth century. Since Kew was the first point of entry for many plants into Britain, and also sent plants to colonial botanic gardens all over the world, this record book is central to our understanding of the circulation of plant species, both nationally and globally. Kew really is a place of infinite riches, for the visitor and historian alike!

Q & A with Ben Fitch from the Riverfly Trust

Hosted by the Freshwater Biological Association, the Riverfly Partnership represents a network of organisations whose aims are to protect the water quality of our rivers, further the understanding of riverfly populations and actively conserve riverfly habitats. This is achieved via a range of ongoing projects which utilise citizen scientists to monitor invertebrates, water chemistry, physical habitat, pollution and hydromorphological functioning in order to gain a picture of overall river health.

Ben Fitch is the national project manager for the Anglers’ Riverfly Monitoring Initiative, one of the projects run by the Riverfly Partnership. This week we chatted to him about the Partnership and their projects, the importance of riverflies and how Covid-19 has affected his working life over the recent months.

If one were to canvas general public opinion about flies, many people would likely think of those which they consider to be pests, such as house flies, mosquitos, greenfly, blackfly and horseflies. How would you explain to a non-specialist how important riverflies are and why we should care about them?

First of all, I would say that all insects are essential to life on this planet, with species fulfilling important roles within ecosystems – even those ‘pesky’ flies as some may see them.

Next, I would highlight the fact that freshwater is a precious natural resource upon which all life on Earth depends. Humans are certainly no exception to that rule, but it is because of us that freshwater is under considerable and continuous threat.

I would go on to explain that riverflies contain three groups of insects, namely mayflies, caddisflies, and stoneflies. More than 280 species of riverflies have been recorded in the UK, most of which spend the greater part of their life beneath the surface of still or running freshwater as larvae, before emerging from the water as winged adults. Riverflies should be present in running and still freshwater bodies across the UK throughout the year, they are at the heart of freshwater ecosystems and are a vital link in the aquatic food chain as a food source for fish and birds.

Importantly, riverflies are sensitive to changes in water quality, for example chemical or organic pollution, which makes them excellent indicators of the health of a freshwater body (they are often referred to as the canaries of our rivers). Thus, by monitoring them regularly, it is possible to identify and manage pollution issues, deter would-be polluters, and protect our freshwater ecosystems.

Does Britain have any endemic or particularly rare riverflies?

There are eight rare and threatened riverfly species that have been designated as conservation priorities by the UK Government. The eight species, listed as follows, are categorised as being of Principal Importance:

Northern February red (Brachyptera putata): a stonefly that occurs only in Britain. It is found mainly in Scottish upland streams.

Rare medium stonefly (Isogenus nubecula): only known to occur in the Welsh River Dee and may now be extinct.

Scarce grey flag (Hydropsyche bulgaromanorum): a large caddisfly only known from stony areas on the River Arun in Sussex.

Scarce brown sedge (Ironoquia dubia): a caddisfly only known from three southern English sites. There are no recent records for this species.

Small grey sedge (Glossosoma intermedium) a caddisfly that has been found in only four Lake District streams. There are no recent records for this species.

Window-winged sedge (Hagenella clathrata) an orange mottled caddisfly that lives in pools on bogs and heathland at about ten sites in the UK.

Southern iron blue (Baetis niger): a widespread mayfly species whose abundance appears to have declined in some areas by as much as 80% in recent decades.

Yellow mayfly (Potamanthus luteus): an attractive, bright yellow mayfly that is found mainly on the River Wye in the Welsh borders.

[I would like to give great thanks to Craig Macadam, Conservation Director at Buglife – The Invertebrate Conservation Trust, for permitting me to use information from the Buglife website in parts of this interview, particularly above. To find out more about why bugs are essential to our planet and all life on it, visit: https://www.buglife.org.uk].

The Riverfly Partnership coordinates a number of projects looking at lots of different measurements of river health. These include surveying invertebrates, physical habitat, hydromorphological features and pollution events. What happens to the data that is collected in these projects? Who uses it and what for?

Firstly, I should clarify that the Riverfly Partnership (RP) is hosted by the Freshwater Biological Association and is a network of more than 100 partner organisations representing anglers, conservationists, entomologists, scientists, water course managers, and relevant authorities. RP carries out work according to its core aims: to protect the water quality of our rivers, to further the understanding of riverfly populations, and to conserve riverfly habitats.

As your question states, RP is involved in a number of citizen science freshwater monitoring initiatives. Here is a summary of those initiatives along with how data is collected, stored, and used in each case:

Anglers’ Riverfly Monitoring Initiative (ARMI)

The Anglers’ Riverfly Monitoring Initiative (ARMI) is a project that enables trained volunteers, such as anglers and conservationists, to protect river water quality by regularly monitoring eight pollution sensitive aquatic invertebrate groups. Data is recorded in the field before being uploaded to the national online ARMI database (once checked and verified, ARMI data is available under the terms of the Open Government Licence). ARMI complements the work carried out by statutory agency staff across the UK, such as the Environment Agency in England, primarily by reporting pollution incidents to and sharing ARMI data with those agencies directly.

Urban Riverfly

Urban Riverfly includes an additional six aquatic invertebrate groups to the eight used in the original ARMI scheme and can be used across a number of different river systems, but especially modified rivers and those influenced by conurbations. Urban Riverfly data is recorded in the field by trained citizen scientists, hosted locally through Riverfly Hubs, and used by Catchment Partnerships to inform catchment management and direct conservation action.

Extended Riverfly

Extended Riverfly uses 33 invertebrate groups, including the eight ARMI groups, to provide a more nuanced picture of river water quality according to different stressors. Extended Riverfly data is collected, stored, and used similarly to that of Urban Riverfly.

Freshwater Watch

Hosted by the Earthwatch Institute, Freshwater Watch is a global initiative for monitoring water quality and water chemistry. Data is recorded in the field and submitted online by trained citizen scientists, after which experts provide analysis and feedback to monitors and present evidence to decision- and policy-makers worldwide.

MoRPh

The Modular River Survey, or MoRPh, enables citizen scientists and professionals to be trained to assess and record physical habitat and hydromorphological functioning in their local rivers and streams. Data is hosted online by Cartographer and is used by Catchment Partnerships to inform catchment management and direct conservation action.

Outfall Safari

The Outfall Safari is a citizen science method devised to systematically survey outfalls in urban rivers in order to identify pollution and notify the relevant authorities (sharing data accordingly). It was created by the Citizen Crane project team in partnership with staff from Thames Water and the Environment Agency, and is regarded by the Environment Agency as best practice.

SmartRivers

SmartRivers, hosted by Salmon & Trout Conservation (S&TC), takes citizen science invertebrate monitoring to the highest resolution. Species data are recorded in the field then stored in S&TC’s database. S&TC staff process SmartRivers data through their unique calculator and provide data analysis that identifies specific water quality stressors in the river and pinpoints where they are occurring. S&TC use SmartRivers data to provide evidence that can help prevent pollution occurring in the first place. This evidence can also inform how to concentrate management efforts locally to achieve the best environmental outcomes.

Like many people across the UK, you have been furloughed as a result of the global Covid-19 coronavirus pandemic since March 2020, so are not legally permitted to work. As such, we are grateful to you for agreeing to do this interview in a voluntary capacity. Can you describe your role within the Riverfly Partnership and what a typical work day looks like for you?

My working role for the Riverfly Partnership is as the national project manager of the Anglers’ Riverfly Monitoring Initiative (ARMI). The Riverfly Partnership receives funding support for the role from the Environment Agency (rod licence revenue and the Water Environment Improvement Fund). I have also been a committed and active ARMI volunteer monitor since 2009.

At the moment, I would not describe my days as ‘typical’ for the reasons outlined in your question. I have not been able to work since late March, neither has it been possible to carry out ARMI sampling for the larger part of the same period. I am grateful, however, for the excellent ongoing support provided by the Freshwater Biological Association and I hope to be able to return to work in the near future, as soon as government advice permits and once it is deemed safe for me to do so. In the meantime, I have greatly enjoyed spending more time with my family which has largely centred around home educating our two children whilst my wife, as a key worker, has continued to work throughout.

A typical day prior to the current situation was always incredibly busy! My key responsibilities revolve around supporting and expand the ARMI network, including communications, publications, presentations, training delivery, tutor support, tutor/training workshop observations and QA, tutor development, database and website management, and much, much more. I wouldn’t feel right at this point if I didn’t thank every single ARMI volunteer, participant, partner, and supporter for their incredible commitment towards protecting our rivers. I would also like to acknowledge my colleagues Alex Domenge, Steve Brooks, Bill Brierley, Roger Handford, Lesley Hadwin, Kirsty Hadwin, Paul Knight, Nick Measham, Tom Miles, along with every RP Board member, every Extended / Urban Riverfly Working Group member, and every contact at the Environment Agency, Scottish Environment Protection Agency, Natural Resources Wales, and Northern Ireland Environment Agency. As you can see the work that I am involved in has partnership at its core.

If people want to get involved with riverfly monitoring (or any of your citizen science projects) how would you suggest they get started? Do they need prior knowledge/experience of freshwater sampling or species ID?

Volunteering, as a river monitor or riverfly recorder, is not only an excellent way to protect the health of your local river, but also to contribute towards direct conservation action, local communities, scientific data and evidence, and sustainability.

New volunteers are always welcome and no prior knowledge or experience is necessary.

Individuals interested in becoming a volunteer Riverfly monitor should register their interest with their local Riverfly hub coordinator. To find out who that is please use the contact us page on the Riverfly Partnership website: https://www.riverflies.org

Individuals interested in becoming a riverfly recorder should visit the Riverfly Recording Schemes (RRS) page of the Riverfly Partnership website: https://www.riverflies.org/Recording_Schemes where details about the schemes and RRS coordinator contact information can be found.

Organisations interested in joining the Anglers’ Riverfly Monitoring Initiative (ARMI) must have a member who is prepared to act as a local coordinator (to serve as a contact point between the EA / SEPA / NRW / NIEA and the monitoring group) and have members attend an official ARMI workshop. The workshop includes presentations, practical demonstrations and active participation. For more information please contact us via the Riverfly Partnership website: https://www.riverflies.org

For information about freshwater invertebrate and freshwater ecology training courses, I can highly recommend the Freshwater Biological Association: https://www.fba.org.uk

What conservation actions or changes would you like to see happen in your lifetime that would have a significant (and positive) impact on river health and biodiversity?

I could list many here but I am going to go with two, off the bat:

Serious, long term political commitment to the natural world and conservation thereof
Wilding

If you had to tell people to google a photo of one species of riverfly which would you choose? (perhaps because it is ecologically important or just because it looks interesting!)

If I had to choose one, it would be of a flat-bodied mayfly larva (species Ecdyonurus dispar – Autumn Dun) because new volunteers often remark that it looks like an alien! If that stirs your curiosity, type ‘Ecdyonurus dispar’ in to your internet search engine of choice. If you can find an image of the white spot variant that is particularly striking.

I would also like to share this beautiful image, simply named ‘Mayfly’, photographed by Jon Hawkins. This was the winning entry to the most recent RP Photography Competition and I think it deserves to be seen! (Reproduced with kind permission of the Riverfly Partnership, copyright Jon Hawkins.)

Author Interview: Neil Middleton, Is That a Bat?

Neil Middleton is the owner of BatAbility Courses & Tuition, a training organisation that delivers bat-related skills development to customers throughout the UK and beyond. He has studied bats for over 25 years with a particular focus on their acoustic behaviour. Neil is the lead author of the popular Social Calls of the Bats of Britain and Ireland (2014) and in 2016 he wrote The Effective Ecologist which tackles the challenges facing ecologists as they endeavour to perform to the highest standard within their working environment.

His latest book, Is That a Bat?, published in January, provides a technical, yet accessible, guide to understanding and categorising non-bat sounds. Including a downloadable audio library, this ground-breaking book is designed to help bat workers be more confident in analysing their recordings, and also discusses the wider conservation benefits of studying non-bat sounds.

We recently caught up with Neil to chat about the book and about nocturnal sounds and their analysis.

……………………………………………………………………………………………………..

Where did the idea for this book come from? And do you feel that this is a subject/area of study which has been largely overlooked?

The idea came from a number of different directions during the years prior to my starting work on this project. As someone doing lots of sound analysis for bats and also seeing the kind of queries that would get sent to me, it was apparent that bat workers spent at least some time, unproductively, trying to work out what species of bat it was, when it turned out not to be a bat at all.

Additionally, whilst working in darkness we often hear other sounds that get ignored or written off as ‘of no interest’. These sounds (eg a Schedule 1 bird species) could actually be very relevant to the project we are working on and the reason why ecologists are being sent to a site in the first place. Saying ‘I don’t know. It’s not a bat, so it doesn’t matter’ isn’t really the best approach to take. When people see something, they tend to react more positively, as opposed to when they hear an unfamiliar sound. In darkness, however, sound is usually all you get. So, this put ‘in the frame’ the thoughts I had regarding audible sound encountered during darkness.

Finally, I had been asked many times over the years, questions such as, ‘do mice make high frequency sounds?’ Until relatively recently I didn’t have a proper answer to that question and probably, to be honest, didn’t even think that I cared or that it mattered when it came to doing bat work. I could not have been more wrong. Not only mice, but all of our small terrestrial mammals make ultrasonic sounds that can get picked up by bat detectors, and many produce sounds that are quite similar to some of the echolocation pulses or social calls produced by bats.

Having written this book (and completed the immense amount of research that it has inevitably involved) do you now find yourself looking at and treating your own recorded data differently?

Oh yes, most definitely. I am now very nervous about being certain about anything slightly unusual. When I deliver presentations, I often use the expression, ‘You only know what you know’. I feel this underpins my whole thought process now, as it also follows therefore that ‘You don’t know what you don’t know, and how much there is still to find out’. I honestly think, in some respects, we are only scratching the surface when it comes to our knowledge of bat-related sound, as well as all of the other species and things that make noise within a bat’s soundscape. I think we are sometimes far too sure of ourselves for our own good.

Following on from that, it also has consequences to our, sometimes misguided, reliance on automated classifiers. I get quite unsettled when I hear some people talking about complex stuff (eg separating Myotis species with high degrees of confidence) in such an authoritative manner. I have always preferred a more cautious approach, and even more so now. If anything, having now done this project, I would say that I have backtracked, in some respects quite far, from stuff that I once thought I knew reasonably well.

How do you feel about auto-ID software? Do you have concerns that it gives users a false sense of confidence in their results? And do you feel that, as technology becomes more advanced, it might be at the expense of expertise in both fieldcraft and analysis?

To answer the last part of this question first, yes on both accounts. I go into quite a lot of detail within the book as to why I think this way. The pages in the book regarding these areas were written and revisited many times during the process. When I look at my first draft of those pages (which I still have) it is interesting for me to see the journey I have been on and how my thinking changed during the process.

My viewpoint on automated classifiers at the start was quite negative in all respects. In some respects, the classifier challenge isn’t related purely to bats. If only it was, it would be so much easier. I was horrified to find classifiers confidently identifying lots of non-bat-related sounds as bats. This was the point for me where this work moved well into the ‘essential reading for bat workers’ category, as opposed to a ‘nice to know’. I remember that day extremely well. I was in a hotel room, near Gatwick, doing analysis of harvest mouse calls. They looked a bit like common pipistrelles, and the three classifiers I used that day all agreed! After publication, I was especially pleased to see that some of the reviews have very much labelled it as ‘essential reading’, for a number of reasons (ie not just the scenario discussed here).

But putting all that aside, for the moment, my final conclusion (for the time being?) is that there are definitely better classifiers than others, and there are different ways in which classifiers do things that will produce different results. I also feel that classifiers used sensibly, by experienced people (ie those who possess all the ‘essential’ knowledge), with audits in place, can be extremely powerful and useful. However, just like a human, a classifier has got so many things loaded against it arriving at the right answer (much of which is discussed in the book). So, it is fair to say that classifiers can come up with completely wrong answers. It is also fair to say that humans, even with experience, can also come up with completely wrong answers.

Therefore, neither approach is perfect, but the thing I now feel strongest about isn’t the classifiers themselves but, firstly, the lack of training people get in understanding how these systems work ‘behind the scenes’. And secondly, the lack of technical knowledge and experience of bat-related acoustics demonstrated by some of those who use these systems. I think it is too easy for organisations to give this important and often complicated work to junior members of the team, furnishing them with classifiers etc. It is then as easy for an inexperienced person to use these systems, write reports and influence decisions that are being made, without they themselves (or their bosses) appreciating that perhaps they or the classifier is getting it wrong (back to ‘You only know what you know’). Ultimately, during any project, the human decides (or at least they should). They decide what classifier to use. They decide the methods to use. They decide to blindly accept what the system is telling them, or not. They decide to do a proper manual audit of the results, or not. They decide what goes into a report and whether or not to be cautious with their interpretation. In the book I say something along the following lines:

‘Our bat detectors and associated software should be regarded as educated idiots. Very intelligent, but on occasions totally lacking any common sense. There is one part of the process, however, where ‘common sense’ needs to be applied. This is the part where a human decides what to do next. You need to keep pressing that ‘Common Sense’ button before jumping in with wrong conclusions and inappropriate decisions.’

Too many people blame a classifier for making mistakes, when in fact we should perhaps be collectively looking in the mirror. It is a tool, and like any tool there are right ways and wrong ways, right times and wrong times, to use it. ‘It’s a bad workman who blames his tools’. I think if you use a good classifier appropriately, and the methods/results are audited by an experienced person, the combination of the two, each allowing for the other’s weaknesses, can work well.

Do you think that increased awareness of the other noises recorded during bat surveys has wider implications for conservation? For example, can you provide us with a situation where bat survey recordings might be useful for other species/purposes?

Definitely. This is one of the main threads within this work and the examples are numerous. We live in a country which, relatively speaking, isn’t that diverse when it comes to night-time species (bats, other mammals, birds, insects…). But even in the British Isles we have bush crickets, moths, birds, shrews, voles etc that can all be identified either audibly or from the analysis of bat detector recordings. Now take this approach into more diverse parts of the world. We haven’t really begun to scratch many of the surfaces, as far as I can tell. Even just looking at the UK, I don’t believe for one second that ‘Is That A Bat?’ is anywhere close to the total picture of what we may encounter acoustically during darkness. There is so much more to find out and this knowledge will almost certainly lead to better decision making and associated benefits for conservation.

Bat survey technology is constantly progressing, and there is a lot of recording equipment and analysis software on the market. It’s not surprising that it can be confusing for even the most experienced ecologist. What advice would you give to an aspiring bat worker who wants to gain experience and skill?

Listen and learn from lots of different experienced people. Take all of their thoughts and blend these with your own developing technical knowledge and experience. Understanding how bat echolocation works and how this links to behaviour is an essential foundation that should be in place before someone begins to attempt to identify bat calls to a species or group level. For example, the answer is often as much to do with where a bat is (relative to surroundings), as it is to do with what a bat is.

Be wary of anyone who tells you they can identify every bat call, or that the system they use is always right. Don’t be afraid to just call it what you know it is (eg Myotis), as opposed to trying to always get it diagnostically to species level (eg it’s a whiskered bat). In any case, for some jobs you won’t need to know the precise species on every occasion. Why risk your credibility when there is no reason to do so. When you start appreciating the reasons why you can’t identify every bat, you are beginning to become an experienced and respected bat worker. People who don’t really understand this subject are afraid not to identify everything. People who really understand this subject know that everything can’t be identified (not at this stage anyway!).

What was the most interesting, bizarre or unexpected non-bat sound you came across during the research and writing of this book?

I think my favourite is the Long-Eared Owl juvenile call, when slowed down 10 times. This is something many bat workers do with bat calls in order to make them audible, and with an unusual recording it might be how you would first listen to it before realising that it’s not a bat. It still makes me smile, for no scientific reason whatsoever. It just reminds me of ‘Casey Jones & The Cannonball Express’ (the whistle from his steam engine). I know some of your younger readers will need to Google ‘Casey Jones’.

Finally – a question we ask all our authors – what is next for you? Do you have plans for further books?

Yes, two others. But I am scared to say too much at the moment for a number of reasons, including that once you say out loud what you are doing, the pressure is then piled on to get it done. I am just recovering from this one! So, I need some time to carefully consider which of the two ideas comes next and how to marry up the huge amount of time it takes to produce a book with other commitments.
