Author Q&A with Hugh Warwick: Cull of the Wild

In Cull of the Wild, author Hugh Warwick investigates the ethical and practical challenges of managing invasive species to increase biodiversity. He explores the complicated history of species control over time, while also combining scientific theory and subtle humour, to explain the many issues conservationists face when trying to protect native species from their non-native rivals.

Hugh Warwick is an ecologist, conservationist and writer who specialises in the study of hedgehogs. He has published three books focusing on this species, however he recently expanded his field of study to include invasive species while writing Cull of the Wild. He has previously written for BBC Wildlife, New Scientist, The Guardian and The Daily Telegraph, is the spokesperson for the Hedgehog Preservation Society, runs courses on both hedgehog conservation, and lectures in creative writing.

Hugh recently took the time to talk to us about his book, including what inspired him to write Cull of the Wild, how he hopes his book will help future conservation methods, and more.

Firstly, what inspired you to write a book on the culling of invasive species?

The very first independent field work I did in 1986 – for the 3rd year project of my degree – took me to North Ronaldsay. My supervisor had a friend who was both the GP and the bird warden on this island, the most northerly in Orkney. He had noted that there seemed to be a correlation between the increase in number of imported hedgehogs (that was the postman’s fault!) and the decrease in breeding success of ground nesting birds – in particular the Arctic Terns. My work was to try and find out how many hedgehogs there were. This turned out to be around 500 – not the 10,000 the Daily Express had reported! The bird observatory organised an airlift to remove the hedgehogs after I had gone and I returned in 1991 to repeat the survey. Since then I have found the collision of ecological study with human concerns really fascinating.

This led me to become involved, rather inevitably, in the Uist hedgehog saga, where the RSPB and Nature Scotland were killing the hedgehogs for the very same reason they had been airlifted from North Ronaldsay. I quickly shifted from reporting on the story for BBC Radio 4, to joining the campaign against the cull, and then doing the research that helped stop it. But while all this was happening, I met a researcher from New Zealand who was telling me that they were killing hedgehogs over there (in the 1860s we sent a load of hogs over to help the colonialists feel more at home) I could see no reason not to kill those hedgehogs.

That apparent contradiction has been spinning in my head ever since and was the springboard for this book.

How did you find researching such differing opinions on the subject, and have your preconceived opinions changed over the course of writing this book?

I found this book so very different from all the others I have written. Previous outings have always been with people who are just really pleased to talk – to share their enthusiasm for Beavers or Water Voles or owls. This was the first time where I felt like the initial communication was almost like a job interview – assessing whether I was suitable to talk to. Some people simply refused to talk, others were cagey. I guess I was quite naïve!

The journey of the book is basically one where my head and my heart are in constant debate. I lay out my ‘bunny-hugging’ prejudices at the start. I suppose I was hoping to find that all instances where animals were being killed could be dealt with in other ways.

One of the biggest lessons I learnt, though, was about how people, even ones with whom you have fundamental differences of opinion, share so much common ground. But you will never see that common ground if you charge in at the difference! I love that one of my potentially conflicting interviews ended up with the biggest argument being over who recorded the best version of Sibelius’ 5th Symphony!

In Chapter 1, you discussed that animals are shown to be continually developing to become more like humans – problem solving, making and using tools etc. Do you think this gradual form of humanisation may lead to more equal ‘rights’ between animal species and humans in relation to killing for conservation?

I would not look at this as humanisation – that is slipping back into the human exceptionalism that got us into this mess. Currently the degrees of cruelty we deliver to wildlife is arbitrary, based in large part on language and on the names we give them, even different members of the same species.

We need to recognise that these animals being killed experience pain, joy, fear and hope. If the realisation that different species have the capacity to do human-like things is enough to get this recognised, then that is some progress.

I have been gently eased away from the concept of ‘rights’ for animals and towards a desire to see cruelty minimised. Rights are important and I see their value – but here, I feel the best outcomes will emerge from a utilitarian desire to maximise good and minimise bad. Though that requires we have the idea that these animals, most of whom are simply in the wrong place at the wrong time, are individuals and can suffer.

You must have visited many places and spoken to many different people about different species while you were writing this book. Were there any particularly memorable moments or experiences that that have stayed with you?

I did not get to some of the places in this book – time, Covid, money and a desire to minimise flying all conspired to keep the exotic interviews on Zoom. But the adventures I did have were all special.

Heading out along the coastline of South Ronaldsay, Orkney, with Spud – the most handsome labrador I have ever met – was magical. The wind blew, the surf crumped in from the Atlantic, and Spud, well, he followed his nose and we followed him as he tracked down evidence of Stoats.

The Stoat story is so important – it is about speed and trying catch this problem early – they were only found in 2011. But more than the practical, it is also about the buy-in of the local population. If the public are not onside, the conservationists can give up now. So it is about education and communication as much as it is about deciding which traps to use and where to site them.

In what way do you hope that Cull of the Wild will help future animal conservation efforts?

The overarching message I hope people get from Cull of the Wild is that ecology is both fascinating and VERY challenging when it is part of a conflict. Ecology is not given the level of respect that it should receive. It is always sidelined – economics and politics hog the headlines – yet both of those are but subsets of the wider ecosystem. Without a healthy ecosystem we are on a downward slope to disaster. So, I hope that people will read this book, maybe because they are outraged at the killing, and will then come away realising that ecology is very complex and should be treated with great respect.

I also hope that this book will convince people who hold very firm opinions – opinions that are often amplified by the bubbles in which we tend to linger – that people with differing views may well share many of the same values as themselves. And that to begin discussion at the common ground is the foundation of progress. Argument should not be about winning, but about making things better. Remember, it is quite possible that some of the things you know are wrong. A friend of mine turned up at a conference recently with a t-shirt saying ‘Don’t believe everything you think’. We should be humble enough to recognise we might be wrong.

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

As I write this, the lovely people at the publishers Graffeg are hoping I will stop promoting Cull of the Wild and finish the two books I owe them: one on bats and the other on nocturnal nature. I have another narrative nonfiction brewing – about as different to this book as imaginable. Something which will hopefully bring laughter into our love of nature.

Book Review: Of Cockroaches and Crickets

***** An amusing and light read

Of all the insects that have a PR problem, cockroaches must rank very high. That, however, did not stop German entomologist, journalist, and filmmaker Frank Nischk from spending a year-long internship studying them. In this book, he regales the reader with stories of his time in the lab and the field studying first cockroaches and later crickets. A light and breezy read despite the serious undercurrent of biodiversity decline, Of Cockroaches and Crickets turned out to be an entertaining read.

This book was originally published in German in 2020 as Die fabelhafte Welt der fiesen Tiere by Ludwig Buchverlag and has been translated into English by Jane Billinghurst who frequently works with Greystone Books. Carl Safina contributes a short foreword that cracked me up and immediately set the tone. The book is effectively a memoir of Nischk’s early years studying for his undergraduate and doctorate degrees in the mid-nineties, told in 18 short chapters in two parts. His subsequent career pivot to documentary filmmaking only receives passing mention.

Given Nischk’s concern about biodiversity decline, and his desire to communicate to a broad audience why insects are fascinating and important, there is an irony to his undergraduate internship. He spent a year in the lab of Martin Dambach studying the aggregation behaviour of the German cockroach, Blattella germanica. By day, large groups of them bed down on their own excrement, likely attracted by pheromones released by the faeces. The irony? Nischk’s internship was funded by biotechnology giant Bayer which was hoping to isolate the chemicals responsible for putting the cockroaches in sleep mode to develop a pheromone-based cockroach trap: “the exterminator’s holy grail” (p. 25).

For his subsequent doctoral studies, Nischk got his conservation priorities in order. Staying with Dambach, he turned to crickets and spent time in Ecuador recording their songs. Next to discovering species new to science, this is his entry into the fascinating field of soundscape ecology or ecoacoustics. A small cadre of ecologists has been recording soundscapes of natural habitats. Bernie Krause (not mentioned here) is one particularly well-known example. By comparing recordings made years or decades apart they have shown how natural soundscapes are changing and often disappearing due to human encroachment. Others are hoping to train software to analyze recordings and identify species by their calls. If scaled up, the dream is to have passive acoustic monitoring stations in biodiversity hotspots around the globe.

This backbone of his research is livened up with personal anecdotes and interesting asides. A friend’s call about a wasp infestation in her kitchen drawer is an excuse to introduce the 18th-century French entomologist Jean-Henri Fabre who was one of the first European naturalists to systematically collect and study butterflies, beetles, and wasps. Getting stung by a bullet ant in the rainforest of Ecuador leads to an aside about the late entomologist Justin O. Schmidt, the man who got stung for science (and wrote a fine book about it too). Tracking down a particularly loud cricket in Ecuador is the starting point for an unusual case where entomologists helped to defuse international political tensions between the USA and Cuba (this story has a surprising twist that I will not spoil here). A botched attempt to eradicate cockroaches that escape his experimental setup backfires most spectacularly, while fieldwork in the tropics is always fodder for amusing cultural misunderstandings and sober reflections. There is a nice mix here that never dwells on any one topic too long and makes for a book that is hard to put down.

The third and final part is, perhaps surprisingly, comparatively the weakest of the book. In four chapters Nischk muses on the biodiversity crisis, particularly the still poorly understood decline of insects, and discusses examples of individuals and organisations who are creating and protecting wildlife habitat. Probably most interesting are the little-known grassroots initiatives in Ecuador that are undertaken by villagers and farmers turning to ecotourism. But is this really the answer? Or does it merely perpetuate the idea that nature can only be protected if it has monetary value? You will not find a critical or comprehensive analysis of wildlife conservation here. There is also an odd focus on projects in the USA, e.g. the High Line in New York, the Xerces Society, Joan Maloof’s Old-Growth Forest Network, and the Yellowstone to Yukon Conservation Initiative. I wonder if this was added for the English translation. There is no mention of e.g. the European Natura 2000 network of protected areas or E.O. Wilson’s bold call to protect half the planet, and only passing mention of the German environmental organisation NABU or the practice of rewilding. Putting aside such nitpicking, none of this takes away from his genuine concern about the ongoing loss of biodiversity nor from his conclusion that the key to protecting species is protecting their habitat.

Overall, Of Cockroaches and Crickets is an amusing and light read that I devoured in a day. Nischk offers a nicely balanced blend of interesting natural history, amusing personal stories, and captivating scientific research. Whether it is flies, wasps, or rats, we need more books that celebrate those species we all too readily dismiss as pests.

Author Q&A with Chantal Lyons: Groundbreakers

Big, messy and mysterious – crossing paths with a Wild Boar can conjure fear and joy in equal measure. In Groundbreakers, Chantal Lyons gets up close and personal with this complex and intelligent species in the Forest of Dean, and investigates the people across Britain and beyond who celebrate the presence of these animals – or want them gone. From Toulouse and Barcelona where they are growing in number and boldness, to the woods of Kent and Sussex where they are fading away, to Inverness-shire where rewilders welcome them, join Chantal on a journey of discovery as she reveals what it might take for us to coexist with the magnificent Wild Boar.

Chantal Lyons is a naturalist, writer and science communicator. Having grown up in the tidy countryside of Kent, her encounters with the growing rewilding movement opened her eyes to the potential for restoring nature in Britain, and inspired her to study the relations between people and Wild Boar in the Forest of Dean. She currently lives in Cheltenham, never too far from the boar.

Chantal recently took time out of her busy schedule to tell us about her first experience with a Wild Boar, her hopes and fears for the future of their populations in Britain, and more.

First of all, could you tell us a little bit about yourself and what led you to writing a book about Wild Boar in Britain?

Up until my mid-twenties I spent all my writing time churning out unpublishable fantasy and sci-fi novels, alongside a zig-zagging career in the charity sector. The journey to Groundbreakers was perhaps a ponderous one – it started when I went to the Forest of Dean in summer 2014 to research a Masters dissertation in environmental social science. The Forest of Dean was, and still is, one of the few places in the country where Wild Boar have returned since their extirpation from Britain around 700 years ago. I wanted to find out from local residents what it was like to suddenly find yourself living alongside a big, wild, and utterly unfamiliar creature. What I discovered from those interviews astounded me, and I was sure that some established nature writer would soon publish a book about the return of boar to Britain and what this meant for us. No one did. After seven years, I decided to send off a proposal to a publisher who I’d encountered on Twitter, and it snowballed from there.

Could you tell us about your first real life experience with a Wild Boar?

It was a long time in coming! While I was in the Forest of Dean doing the Masters research, I used every spare moment to explore the woods on my own, often following locals’ leads. It always came to nothing. The boar seem to be like cats – you seem to be more likely to meet them the less you want to. But eventually, at the tail end of summer, I went to a spot where I’d heard from someone that a sounder (a family group of boar, which is always led by a matriarch) had been foraging each evening. I heard them softly calling to each other, then there was a rustling in the bracken, and an adult stepped out onto the path to get a look at me. We stared at each other for about two seconds, she gave a belching alarm call, and then she vanished with her family.

I appreciated the ways in which you speak about rewilding, in particular the importance of nuance and accepting the unknown. Do you think that uncertainties about the best way to undergo reintroduction projects and their expected outcomes are a significant hindrance to their implementation?

I have heard many a time from rewilding practitioners that the inherent uncertainties in rewilding can make it especially challenging to gain funding, given that projects aimed at restoring nature have traditionally been expected to be able to set clear targets and end-goals. But beyond practicalities like money, I think the bigger challenge is the attitude that reintroducing species for rewilding purposes is too big an unknown, and therefore too big a risk. Of course we should aim to conduct as much scientific research and gather as much knowledge as possible, but we are running out of time to reverse the haemorrhaging of our biodiversity in Britain and globally. To me, it beggars belief that we seem quite happy to continue doing all kinds of things that we know are massively damaging the environment, but reintroducing species? Why, that’s a step too far!

One part of the book that particularly resonated with me was in ‘The Risks of Being Alive’ where you speak about how, for most modern humans, ‘nothing matters more in life than eliminating all risk to it – even at the cost of happiness’. What do you think it would take for humans to accept more wildness into their lives?

Maybe it’s a cliché to say this, but I think it hugely helps to engage children with nature from a young age, and to continue doing so as they grow up. That of course means ensuring that everyone can access nature.

Beyond that, the question of how to convince people to accept more wildness is an incredibly tricky one, especially in a place like Britain which suffers so badly from ‘ecological tidiness disorder’ (as Benedict Macdonald puts it in Rebirding). The problem is that most of us have not made the connection between our tidy sterilised surroundings and the loss of nature. There is a lack of understanding that the majestically bare plains of Dartmoor or our rolling green fields mean an absence of life; and that you need all manner of species, including big ones, to ensure healthy ecosystems. I didn’t realise this for years. But once you know, you can’t stop wanting to bang the drum.

What are your biggest hopes and worst fears for the future of Wild Boar populations in Britain?

I want the planned, country-wide reintroduction of Wild Boar to become accepted both politically and societally. In the meantime, I hope that the few boar we do have are allowed to thrive. That means more oversight of people carrying out legal shooting of them on their land, and – in the case of the Forest of Dean population – better censusing methods to ensure they are not over-culled (though some culling will always be needed, as the boar currently lack other predators).

What am I most afraid of? That very soon, a disease called African Swine Fever (ASF) which burns through pig populations like wildfire will make its way into Britain. Since Brexit, border controls on pork imports have been so lax that experts think it’s only a matter of time before ASF reaches us. Forestry England is primed to wipe out every last boar in the Forest of Dean if the disease is ever detected in the population. And once they’re gone, it seems very unlikely that they would ever be reintroduced (legally or illegally) again. We will miss a miraculous chance to kickstart the landscape-scale restoration of nature in Britain.

Finally, what is occupying your time at the moment? Are there plans for further books in the pipeline?

I work full-time as a science communicator, which does narrow my research and writing windows! But I am currently working on a proposal for book number two. It’s intended to be something of an evolution of Groundbreakers, picking up a thread that often emerged during my research interviews with people, but which I couldn’t possibly have fitted into this first book…

Groundbreakers is available from our online bookstore.

Author Q&A with Robert Wolton: Hedges

In Hedges, Robert Wolton brings together decades of research and personal experiences from his farm in Devon to explore the ecology, biology, nature conservation and wider environmental values of the hedges in the British Isles. Containing over 300 photographs and figures, this latest addition to the British Wildlife Collection offers a detailed commentary on hedges and their importance in our landscape.

Robert is an ecological consultant and writer specialising in the management of farmland and associated habitats for wildlife. He is a former hedgerow specialist for Natural England, the founder, chair, editor and lead author of the Devon Hedge Group, has been involved in Hedgelink since it began, and has written a number of reports and articles specialising in hedges.

Firstly, can you tell us a little bit about yourself and how you came to be contributing to the British Wildlife Collection with a book on hedges?

I’ve had a life-long interest in natural history, even as a schoolboy I was a very keen birdwatcher. Later, at university, I trained as a zoologist with a strong interest in mammals, although subsequently I have been more involved with insects, especially moths and flies. It was perhaps inevitable that I should pursue a career in nature conservation. My passion for hedges was awakened when we bought a small farm in the heart of Devon, my wife, Paula, looking after the cattle and sheep while I went to the office. Initially it was the flower-filled meadows that drew me to the land, but I soon realised that the many thick hedges, full of different trees and shrubs, were glorious and just as special, particularly when I discovered that those small spherical nests I kept finding were made by Hazel Dormice. At that time, 30 years ago, hedges were very under-appreciated in the nature conservation world – there was a gap waiting to be filled and I was able to persuade my bosses in English Nature to allow me to become a part-time national hedge specialist, a role I continued to fill after the organisation morphed into Natural England. Partial retirement gave me the opportunity to write a book on my beloved hedges. I’d always dreamt of having a volume in the British Wildlife Collection, much admiring the series, so when Bloomsbury offered me the chance I jumped at it.

I tend to think of hedges as being man-made. But is there such a thing as a natural hedge? And if so, how do these come about?

Most hedges in Britain and Ireland are indeed man-made. Some, though, have grown up naturally along fence lines and ditches – these are termed spontaneous hedges and I think they are becoming more frequent, especially along the sides of roads and railway lines. Trees and shrubs, their seeds carried by wind, birds and mammals, can colonise strips of rough grassland remarkably quickly, often protected to begin with by brambles. It does not take many years before there’s at least a proto-hedge present, and after a decade or two it may be difficult to tell it was not planted. Another way hedges have come into being is through strips of woodland being left when land is cleared for agriculture. These are called ghost hedges. Their origin is often given away by the presence of unexpectedly high numbers of trees and herbs characteristic of ancient woodland because they have poor dispersal abilities.

I particularly enjoyed the chapter in your book on the origins and history of hedges. Do you think that the study of hedges can give us an insight into the natural and social history of our country?

Without a doubt. Throughout our countryside, away from the open moors and fens, the pattern of fields, as defined by hedges and sometimes drystone walls, allows the history of the landscape to be read, often going back centuries, even sometimes millennia. We are so fortunate in these islands still to have this landscape continuity – it has been lost over much of continental Europe. In places like Dartmoor, which I can see from our farm, layer upon layer of history can be unpicked through studying the networks of field boundaries, most of which are banked hedges. Some can be traced back to the Bronze Age, 3,500 years ago. This may be exceptional, but even so, most of the hedges in Britain, and many in Ireland, probably date back to Medieval times. They are a hugely important part of our cultural heritage. We love our hedges. This is evident not just in the countryside, but across our villages, towns and cities, in our gardens and parks. Hedge topiary is, after all, a national pastime!

As you describe early on in the book, there are many different types of hedge, from those that consist of just a single species to very diverse multi-species ones, even ones that have been allowed to mature into lines of trees. Is there a type of hedge that is best for the surrounding wildlife and environment and that we should be trying to replicate or maintain as much as possible?

If you put me on the spot, I’ll answer this question by saying that thick, dense, bushy hedges are the best for wildlife, preferably with margins full of tussocky grasses and wildflowers. But really we should be thinking about what networks of hedges look like, because there’s no such thing as a perfect hedge. Different birds, mammals and insects like different conditions, and in any case you can’t keep a hedge in the same state for ever, however carefully you manage it. Basically, the trees and shrubs are always trying to reach maturity, and as they do so gaps develops beneath their canopies and between them. That’s when laying or coppicing are needed, to rejuvenate the hedge and make it more dense and bushy. A lot more research needs to be done on this, but probably, from a wildlife point of view, at least half of all the hedges in a network, say that covering a decent-sized farm, should be in this condition. On the other hand, from a climate perspective, where we need to capture as much carbon as quickly as possible, tall hedges with many mature trees are best. You can see there are tensions here, all part of the challenge of managing hedges well. Who said it was easy?

As both a farmer and an ecologist, I’m sure you are more attuned than many to the conflicting needs of making a living from the land and managing hedges for the benefit of wildlife and conservation. Do you think financial incentives are the only way to encourage landowners and farmers to both plant more and maintain existing hedges?

Financial incentives like government grants will always be important to landowners and farmers because good hedges benefit society at large just as much as those who own and manage them. Things like plentiful wildlife, carbon capture, reduced risk of homes flooding and beautiful landscapes rarely bring in any income to offset costs, let alone profit – it is right that they are supported from the public purse.

Still, hedges can be of direct financial value to farmers through serving as living fences, preventing the loss of soil or providing logs and wood chips for heating. They can also increase crop yields through boosting numbers of pollinators and the predators of pests. To some extent, these direct benefits to farm businesses have been forgotten in recent decades in the drive for increased food production regardless of environmental cost, but they are now being appreciated much more as new ways of working the land, such as regenerative farming, catch on.

And we should not overlook the fact that more and more landowners and farmers are prepared to bear at least some of the costs of good hedge management simply because they gain huge satisfaction from healthy hedges and all the wildlife they contain. The pleasure of seeing a covey of Partridges or a charm of Goldfinches, or hearing the purring song of the Turtle Dove, cannot be priced.

Finally, how did you find the experience of writing this book, and will there be other publications from you on the horizon?

This is my first ‘big’ book, and I was apprehensive to say the least when I started writing it, in 2022. But with a lot of encouragement from my wife and friends I soon got into the swing of things. Challenging for sure but personally most rewarding – exploring new facets, checking information and trying to find the best way to pass on my enthusiasm for the subject. Above all, it felt good to share knowledge collected over many years. Bloomsbury’s support was invaluable, there’s no way I could have self-published. As to whether there are more books in me, I’m not sure. Perhaps one on hedges in gardens? There again, I have a passion for wet woodland, another habitat that’s been much neglected. It’s all too soon to say.

This week in biodiversity news – 19th February 2024

Climate Crisis

A new study reveals the Amazon rainforest’s worst drought on record in over half a century, with human-caused climate change acting as the driving force behind these weather extremes. The Amazon rainforest plays an important role in the removal of CO₂ from the atmosphere, and accounts for around 10% of the world’s species. However, scientists suggest the Amazon could soon reach a “tipping point”, with droughts such as these expected every 13 years if global temperatures increase by a further 2°C.

Conservation

Black Rhinos have returned to Kenya’s Loisaba Conservancy as species recovers following local extinction 50 years ago. This translocation project, the result of a collaboration between Loisaba Conservancy and Kenya Wildlife Service, was prompted by the news that Kenya’s 16 Black Rhino sanctuaries are rapidly running out of space due to a boost in population numbers. Twenty-one of these critically endangered Black Rhinos were released into a specially created fenced sanctuary that covers nearly half of Loisaba’s total area, marking an important moment in the long-term future of Black Rhino populations in Kenya.

Hedgehog populations are on the rise according to BBC Gardeners’ World survey. Previous reports have found that since 2000, the number of hedgehogs has fallen by 30%-75% depending on the area due to increased habitat loss, fragmentation, pesticides, and a reduction in food sources. However, the annual hedgehog survey highlighted a 33% increase in sightings, up from 31% in 2022, which has been aided by the instillation of ‘hedgehog highways,’ and nationwide rewilding efforts. CEO of the British Hedgehog Preservation Society, Fay Vass, stated that urban populations are still lower than they should be, however these results provide cautious optimism for the future of hedgehogs.

Environment

Hailed as one of the world’s most ambitious environmental policies, Biodiversity Net Gain came into effect in England on the 12th February 2024. It is now mandatory for all new developments in England to deliver at least a 10% net gain in biodiversity or habitat on all new sites. In light of the government target of building 300,000 new homes a year by the mid-2020s, it is hoped that the scheme will minimise or mitigate the environmental effects of these new developments.

Iceland may be entering a new volcanic era, with increasing volcanic activity reported across the island. The most recent short-lived eruption on the Reykjanes peninsular marks the third since December 2023, and the sixth since 2021. Researchers think this wave of volcanic activity may be following a pattern that could last for decades, or even centuries. Scientists are trying to work out how to predict future eruptions by tracking ground inflations as magma rises, from which they can estimate when the magma will break the surface.

Science and discoveries

The latest strain of bird flu has decreased Great Skua populations by 75% and Northern Gannet populations by 25% in the past 2 years alone, says the RSPB and British Trust for Ornithology (BTO). According to a recent report, the H5N1 strain has been noted as one of the biggest conservation threats facing numerous seabird species across both UK and Europe. The latest Seabird Count survey, published in November 2023 – which did not take into account the effects of bird flu – found that almost 62% of seabird populations were already in decline across the UK due to other factors such as fishing and offshore wind developments.

The most vulnerable migratory species are at risk due to increased human activity, with one in five threatened with extinction according to the UN. Despite the signing of the Convention on the Conservation of Migratory Species of Wild Animals over 40 years ago, researchers suggest that more focus has been placed on preventing illegal animal trading rather than upholding the law on illegal killing. The report recommends that countries need to establish key biodiversity areas on the migration pathways of endangered species, reduce infrastructure obstructing migration routes, create corridors of protected land, and restore 30% of degraded marine and land areas.

British Wildlife Collection: interview with series editor Katy Roper

The British Wildlife Collection is a series of beautifully presented books on all aspects of British natural history. Since the series began in 2012, it has covered such diverse topics as mushrooms, meadows and mountain flowers, and books have been written by some of Britain’s finest writers and experts in their field. Filled with beautiful images, these wide-ranging and well-researched titles are a joy for any naturalist who is passionate about British wildlife and landscapes.

Katy Roper is a Senior Commissioning Editor at Bloomsbury Publishing and is responsible for the British Wildlife Collection. She recently took some time to chat with us about this excellent series; how it began, what makes it stand out from others of its kind and what we can expect from the collection over the next year. Keep reading for the full conversation with Katy, and browse the full British Wildlife Collection at nhbs.com.

Firstly, could you tell us a little bit about yourself; what you do and what your involvement is with the British Wildlife Collection?

I’m a Senior Commissioning Editor in the wildlife team at Bloomsbury Publishing. The British Wildlife Collection is one of the lists I’m lucky enough to look after; I’m responsible for signing up new books with authors and then seeing them through to the point at which they go off to the printer. Being immersed in these books means that I’m always learning something new: from the surprising fact that saltmarsh occurs as far inland as Staffordshire, through to how to successfully use a pooter to collect ants (without inhaling live insects!).

Published in 2012, the first title in the series was Mushrooms by Peter Marren. Could you tell us more about how the British Wildlife Collection initially came about?

Yes, the series was conceived by Andrew Branson who founded and, for 25 years, ran the publication of the excellent British Wildlife magazine. I believe that Andrew’s intention was to produce a series of seminal books that would capture the essence of the magazine in terms of being informative, well-written and thought-provoking whilst providing the author the space to explore their chosen subject in detail and develop the overall narrative.

For anyone unfamiliar with the books from this collection, how would you describe them and who do you consider to be their intended audience?

The series covers all aspects of British natural history and we encourage our authors to cover elements of ecology, history, management, conservation and culture; in other words, to explore the human relationship with their particular subject. The books are written in a way that we hope appeals to a wide readership, from academics and conservation professionals through to enthusiastic amateur naturalists and people who simply want to know more about the British countryside and its inhabitants.

All the books in the series are incredibly well-researched and comprehensive. How long does it typically take to go from conception to publication for a single title?

It varies depending on the author and their other commitments, but I’d say it typically takes around three years from the date the contract is signed until the book hits the shelves. I think our record for the shortest time is 13 months (I won’t tell you the longest!).

The books are beautifully produced and printed and, without exception, are authored by the most well-respected experts in their field. It is no surprise that they have rapidly become collectors’ items for so many British naturalists. What do you think makes these monographs stand out from others of their type?

The series is relatively new and is still evolving, but our ultimate aim is to build an indispensable reference source on all aspects of our wildlife by commissioning some of our finest writers and leading experts to write accessible and engaging books that are then carefully designed to incorporate hundreds of carefully chosen photographs and illustrations to bring the text to life. We hope that our readers come away from them, as one reviewer put it, ‘better-informed than ever, but also hugely entertained’. Oh, and they each feature a beautiful specially commissioned cover artwork by the peerless Carry Akroyd.

Finally, are you able to give us any information as to what subjects we can expect to be covered in the next year or so, or is this a closely guarded secret?

Hedges by Robert Wolton is coming out in February this year, and beyond that we’re excited to be welcoming Peter Marren back to the series with a book entitled Rare Plants. He’ll be followed by Trevor Dines with Urban Plants and David Goode with Bogs.

All books in the British Wildlife Collection are available from nhbs.com. Please contact our customer services team if you would like to set up a standing order for this series – this will ensure that you automatically receive each new title as soon as it is published.

NHBS manufacturing – a year in review

2023 proved to be a pivotal year for the NHBS manufacturing team, one in which we enjoyed new and continued partnerships with key organisations, overhauled the NHBS Harp Trap with the aid of leading UK ecologists, and continued to refine our existing products.

A glimpse into the manufacturing workshop at the NHBS offices in Totnes, Devon.

Fine tuning the NHBS Moth Trap

Since its introduction in late 2019, the NHBS Moth Trap has been a consistent favourite with hobbyists and professionals alike. However, a manufacturing team consistently motivated to improve our products and with an ear to the ground for customer feedback resulted in an evolution of the trap in 2023. The new design is more robust, lighter and more cost-effective.

By changing the design of the lamp support, our manufacturing team were able to reduce the amount of steel used, saving on both weight and cost. We also upgraded the material used for the moth trap panels to a more rigid and environmentally friendly material, constructed from 70% recycled plastic. Finally, our team developed a system that allows the NHBS Moth Trap to run off a 12V battery using an inverter kit. A full night’s trapping is now possible using a single battery.

The NHBS Moth Trap was designed in consultation with Butterfly Conservation. NHBS is proud to support the excellent work they carry out with each sale of the trap.

Nets for every occasion

There is a sense of pride in the development of the iconic orange banded nets that NHBS produce. Without knowing it, you may have seen them in action on prime-time television shows including Springwatch and the BBC flagship series Earth that featured Chris Packham using an NHBS plankton net in the first episode.

Our bestselling Professional Hand Net also forms a key part of the Riverfly Partnership approved survey kit. Our relationship with the Riverfly Partnership dates back to when NHBS originally acquired EFE & GB Nets in 2016, and we are pleased to further support the Partnership by making a donation to them with each sale of the kit. You can find out more about the great work the Riverfly Partnership are doing in our previous blog and on their website.

Conservation research and monitoring

At NHBS we are experienced in working with our customers to either develop or improve equipment for use in monitoring wildlife. Where necessary we seek out experts who can examine the design of the product and give feedback on improvements; not only to meet project requirements, but also to ensure the design is sympathetic to the wildlife that are subject to the equipment’s use.

Early in 2023, we wanted to overhaul our Three Bank Harp Trap and so reached out to respected and experienced ecologist Neil Middleton of Batability. Neil and his team gave crucial feedback on the trap’s existing design and highlighted areas where improvements could be made. This allowed our manufacturing team to refine the design so that it maximised the safety of the bats that were caught, as well as making it easier for ecologists to use. By listening to the experts and users and making their recommended changes to the design, we now have a product that we are exceptionally proud of.

A visiting team from LIST collaborate with NHBS engineers on the exciting NEWTCAM project.

NHBS manufacturing in 2024

This year promises to be full of exciting developments, including the NEWTCAM project that NHBS is working on in collaboration with the Luxembourg Institute of Science and Technology (LIST). As well as providing a novel approach to monitoring amphibians, NEWTCAM represents a very different type of technology for our manufacturing team, giving them a chance to learn valuable skills which can be utilised in future products. The first units are currently in production and will be made available to early users for field testing from spring 2024.

At NHBS we are committed to finding the best materials and are constantly working to improve the sustainability of the production methods we use. If you have a project or product you think we could help with, please do not hesitate to get in touch using our contact form.

Made in Britain Logo

We are also pleased to announce that we have been awarded the use of the Made in Britain logo for all product manufactured in our NHBS workshop in Devon.

This week in biodiversity news – 5th February 2024

Climate crisis

The UK has approved 24 new North Sea oil and gas licenses in the face of significant criticism. The move angered many environmental campaigners and MPs who labelled the decision as “grossly irresponsible”. The government defended the move stating that the oil would be imported from overseas if it wasn’t extracted from the North Sea. Environmentalists have argued that granting the licenses will do relatively little to improve the UK’s energy security and undermines Britain’s move towards net zero emissions.

Conservation

The National Trust has committed to recreating lost rainforests by planting 100,000 trees in North Devon. Temperate rainforests once covered vast swathes of western Britain, but the rare habitat declined due to historic deforestation and continues to face threats from air pollution, invasive species and diseases. It is now one of the most endangered habitats in the UK covering only 1% of Britain’s landmass mostly in Cumbria, Devon, Cornwall, North and West Wales and the West of Scotland. Exceptionally heavy rainfall and high humidity levels allow moisture-loving plants like mosses and lichens to thrive in these areas and the restored rainforest will be a haven for rare specialist plants that depend on this habitat.

Environment

Toxic run-off from roads has been found not to be monitored, according to the BBC. Rivers close to major roads have been tested by campaigners and have been found to contain a cocktail of chemicals and particles from the roads. National Highways has a statutory responsibility to make sure that discharges from its network do not cause pollution and the Environment Agency is responsible for monitoring water pollution in England. However, in response to a freedom of information request, the agency said that it did not regularly monitory run-off. Oil, chemicals and wear from tyres are washed down drains in heavy rain and subsequently flow into rivers and streams causing damage to sensitive aquatic ecosystems.

The government remains largely off track to meet its environmental targets, according to the Office for Environmental Protection (OEP). The OEP’s annual progress report concludes that while some progress has been made, the government is largely off track to meet both targets and legal obligations and that the government must speed up its efforts and implement policies quickly to bridge the gap.

Extinction risk

The Greater Glider is on course for extinction due to a controversial decision by the Australia’s New South Wales environmental watchdog, according to experts. The Environment Protection Authority (EPA) told stakeholders that it was scrapping measures that required a government-owned forestry corporation to search for Glider dens which currently have to be given a 50-metre logging exclusion zone. Experts have told the EPA in no uncertain terms that they are effectively locking in the Glider’s extinction. Greater Gliders rely on between six and 20 den trees for its habitat which is already under significant pressure due to summer bushfires and logging activity.

Science and discoveries

A new map has revealed that England’s hedges would wrap around the Earth ten times if lined up end to end. The map is the most comprehensive to date revealing a total of 390,000 km of hedgerows. Researchers from the Centre for Ecology and Hydrology used Lidar (Light Detection and Ranging) remote sensing data. They found that the South West of England boasted the largest share of hedges accounting for 24% of England’s total with Cornwall leading at the county level. Around half of Britain’s hedges were lost in the post-war period, and while losses have slowed since the 1990s, major threats to Britain’s hedgerows remain.

The birth of a Great White Shark may have been captured on video for the first time. Wildlife filmmaker Carlos Gauna and UC Riverside biology doctoral student Phillip Sternes were filming California’s coastal waters with their drone when they spotted something unusual. By enlarging the images from their video footage and putting it in slow motion, they realised a white layer was being shed from the body of a shark. They believe it was a newborn white shark shedding its embryonic layer.

The Big Garden Birdwatch: NHBS Staff Results 2024

The RSPB’s 45th Big Garden Birdwatch took place between Friday 26th and Sunday 28th January 2024. This annual event is one of the largest citizen science wildlife surveys in the UK and helps us gain an understanding of how our garden bird populations are changing in abundance and distribution over time. Over half a million people took part in last year’s event, recording a total of 9.1 million birds. House Sparrows took first place, despite a gradual 57% decrease in sightings since the first Birdwatch Count in 1979. They were closely followed by the Blue Tit and Starling.

Although the Big Garden Birdwatch has finished, there is still time to submit your results on the RSPB website by the 18th February, or by post before the 13th February. Even if you didn’t see anything, it still counts!

With birds being faced with an increasing number of challenges each year, it’s more important than ever to make your garden and outdoor space wildlife friendly. This can include installing bird feeders or tables which provide an important food source throughout the winter months when natural food sources are scarce., You can also provide clean, fresh drinking water in shallow containers such as bird baths or saucers, and install nest boxes for breeding in the spring. Also, don’t forget to regularly clean and maintain your feeders and baths as this helps stop the spread of disease. Head over to the RSPB website to find out more about how you can help your garden birds.

Meet the new Song Meter 2 ultrasonic and acoustic recorders

Wildlife Acoustics are renowned for their attention to customer feedback which they use to refine their products and ensure they are of the highest quality. It also means their products are some of the easiest and most flexible to use which makes them favourites with researchers around the world.

The latest additions to their range are the second-generation Song Meter Mini 2, Mini Bat 2 and Micro 2. In this blog you’ll find out exactly what’s new in these improved models and which of the original excellent features have been retained.

What’s new?

Increased battery life

• The Mini 2 with AA batteries will now record for up to 625 hours (when using 8 x AA batteries). This is more than twice the amount of the original Song Meter Mini.

• The Mini 2 with Lithium-ion batteries offers up to an incredible 1,565 hours of recording time, making it ideal for use in difficult to access locations.

• The Micro 2 will now record for up to 240 hours with just 4 x AA batteries – a huge 33% increase over the original Micro.

Improved weatherproofing

All Song Meter units are now tested to IP67 standards. This means that, not only are they protected against typical weather conditions, they can also be dropped into water up to a meter deep for 30 minutes without any water ingress. Perfect for the toughest conditions in the field.

New hinged enclosure

The casing has been completely redesigned so that the lid is hinged to the body and opens using a simple latched mechanism. With purposely designed holes to fit cable locks and/or padlocks, you can leave your equipment unattended, safe in the knowledge that your recorder is secure and cannot be accessed by anyone else.

New tripod mount

Further flexibility in siting has been achieved by the addition of a standard tripod mount. The Mini 2 and Micro 2 can now be quickly and easily attached to any item that has a standard tripod connector.

What has stayed the same?

All the Song Meter second-generation recorders still include a low-noise microphone that produces high-quality sound files. The same companion app, available for iOS and Android, is used to programme the recorders, ensuring that you can quickly and easily update them with your existing recording schedules. Finally, all recorders come with the same 2-year warranty, offering you peace of mind when you buy.
