Author Interview with Charles Foster: The Screaming Sky

A summer visitor, the common swift appears suddenly with the change in season, swooping overhead with its unmistakeable call. From their travels to Africa, to their short breeding season in the UK, swifts appear to defy gravity with their extraordinary migratory feats, with some in flight for ten months of the year. In The Screaming Sky, Charles Foster follows the swifts across the world, recounting his travels and the lives of these remarkable creatures.

Charles Foster, author of the New York Times bestseller, Being a Beast, is a writer, barrister and a Fellow of Green Templeton College, University of Oxford. With publication of his latest book due soon, Charles has very kindly agreed to answer some of our questions.

Firstly, could you tell us a little bit about your background and how you came to write The Screaming Sky?

I’m originally from Sheffield, and as a small boy I was obsessed with natural history. One summer I was sitting in a field watching and counting the house martins. Suddenly there was something else there: it was a completely different kind of creature, and it inhabited the air while other birds just visited it. I was immediately drunk on its power and its mastery and its swashbucklingness. It could have ended badly: it might have made me worship power. But (that’s another story) I was spared that fate, and instead started to wonder whether I could know anything at all about something as different from me as that. So I followed them in every way that I could: through books that taught me about their biology, through poems that taught me how impossible it is for human language to tie swifts down, by gazing up into summer skies, by playing recordings of their calls when I was missing them like crazy in the winter, and by travelling along their migration routes, hoping to catch up with them in Africa and everywhere en route. How could I not write about birds that have taught me so much about what it means to be alive?

During your travels, were there any encounters that particularly stood out for you?

Three:

Sitting at the foot of a tower in Greece with the swifts diving so near to my head that I could feel the air from their fluttering on my face, knowing that they were about to leave for Africa, and wondering what the bereavement would do to me.
Sitting at the top of a tree in Oxford amongst a group of swifts which were grazing on the aerial plankton being wafted up from the ground. And seeing the grey triangular tongue of a swift as it snapped at a ballooning spider near my ear.
Being asleep under a bush in Africa, and being suddenly awake, knowing that the swifts that I’d been searching for for so long were going to be there. And they were! It wasn’t that I’d heard them coming (swifts are generally thought to be silent in Africa). It wasn’t that I’d been told to expect them: I’d been told that we probably wouldn’t see them at all. So how did it happen? If I told you my speculations you’d think I was mad.

What were the major challenges you faced while writing your book?

I’m a fat, lumpen, middle-aged man. It’s hard to think of any organism that’s less like a swift. And, as I’ve said already, language (which is pretty inadequate at the best of times) fails particularly obviously when it comes to swifts. That’s bad news for a writer on swifts. And then there were snakes and elephants and rabid dogs and torrential diarrhoea and bush fires and soldiers and downright laziness and roads washed away and guilt at leaving the family behind.

Wildlife has suffered a substantial decline over the last few decades, and swifts have been no exception with a loss of over half of the breeding population. Has your recent experience writing The Screaming Sky left you more optimistic or more pessimistic regarding the future of the common swift?

They watched the continents shuffle to their present positions, and the mammals evolve. They’ll be screaming through the sky long after our own race has been and gone.

Do you have any new projects in the pipeline that you’d like to tell us about?

In August a book of mine called Being a Human: Adventures in Forty Thousand Years of Consciousness will be published. It’s an attempt to imagine how it would have felt to be around at three pivotal moments in the history of human consciousness: the Upper Palaeolithic (when modern consciousness ignited), the Neolithic (when we first started to see ourselves as distinct from the wild world, and started to tame ourselves and other animals), and the Enlightenment (when the universe, which had always been seen as alive, was reconceived as a machine – with disastrous consequences). And at the moment I’m writing a book called The Siege – to be published in 2022 – which is a collection of stories illustrating the challenges of living alongside you and me if you’re a wild thing with all your senses switched on.

Author interview with Roy Dennis: Restoring the Wild

Reintroducing lost species has had a huge part to play in restoring natural processes and enriching biodiversity in Britain. In Restoring the Wild, Roy Dennis MBE documents the painstaking journey to reintroduce some of Britain’s lost apex predators, and the subsequent enormous benefits to our ecosystem.

Leading up to the book’s publication, Roy kindly agreed to answer some questions.

As is made clear from the title of your book, you have a long and amazing history of involvement with conservation projects. Could you begin by sharing what inspired you to pursue a career as a field ornithologist and wildlife consultant?

It really started as a youngster keen on wildlife and living in the Hampshire countryside. Becoming really good at birds and bird ringing which led to a summer job as an assistant warden at Lundy Bird Observatory, instead of going to work at Harwell Atomic Research Station. The following year I was a field ornithologist at the prestigious Fair Isle Bird Observatory, which was fantastic training. There I met George Waterston, the famous Scottish ornithologist, who persuaded me to join him the following year wardening the ospreys at Loch Garten. There I made so many friends in wildlife conservation and became totally convinced that my life was going to be about birds and conservation, restoring species and subsequently ecological restoration.

Of course the obvious aim of a reintroduction project is to bring back a species that has been lost. But in your experience what subsequent benefits are there to reintroductions?

I think in a very damaged world reintroduction projects show there is a chance to bring species back and give people hope. Some species are more important than others from an ecological point of view with beavers being the ecosystem engineer par excellence. My book explains the many advantages of restoring beavers. Other species such as red kites and white-tailed eagle are iconic species, which demonstrate that rare birds can live in the general countryside, not only in nature reserves. Then people can see and enjoy them on the way to work, school or the shops. My whole ethos has been to make rare birds more common and secure for the future.

According to the latest 2019 State of Nature report, about 162 species have thought to have become extinct since the 1500s. How is it decided what species should be prioritised for reintroduction?

It’s more a question of our ability to successfully restore a species, is there enough habitat and food, can we find birds to translocate and what is the likelihood of success. I think the most important action is to take action and not be bogged down by procedures.

You spoke in your book about the opposition to reintroduction projects – what would your response be to address these concerns and opposing views?

The opposition can come from many quarters but the most important thing is to listen to all the concerns and address them. It’s essential to know the species on its home patch and to be able to present a clear message. Usually people’s concerns can be allayed; for example I write in my book about making a special recce to the Netherlands to speak to the experts about white-tailed eagles and agriculture, so that we could give considered views before starting the Isle of Wight project. We have had complaints from some birders that the translocated ospreys at Rutland Water or the sea eagles are not ‘real’ birds and they cannot count them on their lists. But they forget capercaillies were brought back from Scandinavia long ago. But the recent sea eagles flying in southern England have shown that birders just love to know they are back, and hopefully will breed in England again.

In the final chapter of your book you look forward to focus on newer projects, such as White-tailed Eagle reintroductions on the Isle of Wight and the South Coast Osprey Project. But what else would you like to see reintroduced to Britain in the near future?

In my last chapter of the book I’m really talking about handing over the baton to others to take projects forward. I’m very fortunate that Tim Mackrill joined me a few years ago and I love working with our small team. We are always assessing possible projects but would rather do it in a quiet way, really get to know the species on mainland Europe and talk to all the people that are likely to be involved before we go public with an idea.

White-tailed Eagles, Ospreys, Red Kites and Goldeneyes are a few of the species you have helped to successfully restore to Britain. What has been your personal highlight and why?

“What is your favourite?” is a question I’ve been asked all my life. But I do not have one – or rather it is the one we are working with at the time. I can recall personal highlights like the first osprey breeding pair at Rutland Water, seeing the young white-tailed eagles fly free on the Isle of Wight was exciting just like when I released the first young sea eagle on Fair Isle in 1968. Seeing red kites, the length and breadth of Scotland and England has been special, made more so when you see them soaring over motorways. During lockdown it’s been marvellous to hear from so many people who have seen a sea eagle fly high over them as they sit in their garden. Bringing wonder back.

The Roy Dennis Wildlife Foundation has achieved a great deal over the years since it was formed in 1995, not just in the UK but across Europe too. Can you share what the Foundation has planned for the future?

We want to carry on with our work with wildlife conservation, there are still many things to do and the return of the Lynx is high in my thoughts. We have others in mind for the future so keep an eye on our website and see what’s coming next. You will get a great insight to how these projects evolve and work in Restoring the Wild.

Author Interview with Dave Goulson: Gardening for Bumblebees

From the Sunday Times bestselling author of The Garden Jungle and A Sting in the Tale comes the much anticipated Gardening for Bumblebees. Part identification guide, part instruction handbook, Gardening for Bumblebees is packed full of information and ideas on how to create pollinator-friendly spaces for all types of garden.

As well as an award-winning author, Dave is also a Professor of Biology at the University of Sussex and founder of the Bumblebee Conservation Trust. We have recently had the opportunity to ask him some questions about his latest book.

Could you start by telling us how you came to write Gardening for Bumblebees, and how it differs from your previous book, The Garden Jungle?

Gardening for Bumblebees is a practical, full colour, nuts-and-bolts guide to encouraging bumblebees and other pollinators in the garden, including detailed sections on choosing the best flowers, creating meadow areas, building bee hotels, propagating plants yourself, organic pest control, and more. I hope that it will inspire people, and provide them with all the knowledge they need to turn their garden into a haven for wildlife.

In your book you mention several citizen science projects, such as BeeWatch and BeeWalk, both run by The Bumblebee Conservation Trust. What is the aim of these projects, and how are they beneficial?

If we are to effectively look after our bumblebees and other wild insects we need to know where they are, and how their populations are changing over time. Then we can target conservation efforts to the species and places that most need them, and see whether the things we are doing to help are actually working. Members of the public – “citizen scientists” – have an enormously important role to play here. The UK Butterfly Monitoring Scheme is a great long-running example, whereby the efforts of thousands of unpaid volunteers now provide a really accurate picture of how our butterfly populations have changed since the 1970s.

Your book is filled with fascinating facts about bees that I previously did not know. In your opinion, what have you found to be the most surprising discovery in regard to bees?

I first became hooked on studying bumblebees when I noticed how a bee in a patch of flowers will often fly up to a flower but then veer off without landing. I wondered what was wrong with these flowers. It took five years of research to find out that they were sniffing the flowers for the faint smelly footprint of a recent bee visitor – which would indicate that the flower is likely to be empty. Bees use lots of clever tricks like this to help them gather nectar and pollen efficiently. They are remarkably clever!

You mention in your book your fascination with bees from an early age. How do you think we can best encourage environmental awareness in young people?

We need to make sure that young people have regular opportunities to interact with nature, so they do not grow up regarding insects as alien, unfamiliar, and scary. I’d love to see every school having access to wild greenspace, and more support to help teachers themselves learn about nature so that they can enthuse the children. I’d also pair every school with a nature friendly farm, and provide support so that the children could visit the farm at least once or twice a year, to understand the connections between growing food and nature.

There has been much public concern regarding bees, pollination, and the future of our crops. With the increase in publicity and information on how we can make simple changes to help secure the bumblebee population, do you feel hopeful for the future?

It is great to see the growing public appetite for making gardens more wildlife friendly, and councils also reducing mowing and introducing meadow areas to parks. However, to really make a difference we need farming, which covers 70% of the UK, to move away from the current highly intensive approach, which is reliant on many pesticides. The new Agriculture Bill and Environmental Land Management Scheme might, if done properly, provide a mechanism for positive change.

Alongside the Buzz Club, a citizen science project that is focused on garden wildlife, do you have any other projects on the horizon you’d like to tell us about?

I have another book out in August 2021, Silent Earth. It is a blunt assessment of the dire plight of insects globally, but with suggestions as to how we could halt and reverse their declines. I hope it will help to persuade people that we are in a time of crisis, and that we need radical change.

Author Interview with Andrew Painting: Regeneration

The Mar Lodge Estate in the heart of the Cairngorms was acquired by the National Trust for Scotland in 1995, and has since experienced landscape-scale restoration with outstanding results. Discussing conservation, rewilding and land management, Regeneration is an honest account of both the progress made at Mar Lodge Estate and the challenges faced over the last 25 years.

After studying Environmental Anthropology at Aberdeen University, Regeneration author Andrew Painting moved to Scotland to volunteer with the RSPB. Since 2016, he has been Assistant Ecologist at the Mar Lodge Estate, and has documented its slow recovery. He has very kindly agreed to answer some questions about his book.

Could you tell us a little about your background and where the motivation for this book came from?

I’m a lifelong naturalist, but it took me quite a while to take the plunge into working professionally in conservation. My first degree was in English Literature, so I’m glad I’ve finally been able to put it to good use! I’ve been working in the ecology team at Mar Lodge since 2016, when the fruits of two decades of hard work were beginning to show, and I instantly fell in love with the place. By 2018, all the graphs and reports we were producing were looking very respectable, and I realised we were sitting on a story that deserved a larger audience than it was getting at the time. 2020 was the 25th anniversary of the National Trust for Scotland acquiring the site, and one eighth of the way into the Trusts’ 200 year management vision for the land, so it seemed like a good time for a stock-take.

Of course, it’s never as simple as that. Mar Lodge Estate is not perfect (nowhere is), and as I got down to writing the book I realised that the social and political complexities of the ‘Mar Lodge experience’ were just as important to discuss as the successes.

Though far more is needed to keep up with the increasing levels of environmental destruction, you write of much hope for the future. What do you think is the current biggest challenge conservationists are up against?

Often, the biggest challenge to solving any problem is getting people to accept that there is a problem in the first place. Thanks to decades of campaigning from people from all walks of life, I think we are now at the point where there is broad agreement about the scale of the twinned environmental and climate crises, and the necessity of social change to address them. Politicians across the political spectrum are waking up to the fact that environmental conservation is both a vote-winner and also extremely good value for money, while the private sector is realising that nature-based businesses can be both highly profitable and enjoy high levels of public support.

So now I think that the challenge is to be bold and ambitious, and to make the most of this ‘unfrozen moment’. We need nature, not just in our National Nature Reserves and SSSIs, but also in our farms and seas, along roadsides, in our urban areas, schools and places of business. We now need to lobby those increasingly receptive politicians to instigate progressive policies that incentivise returning nature to these places. To that end, for me, the real power of Mar Lodge Estate is not in the amount of wildlife or carbon it holds, but in the example of ecological restoration that it sets to other Highland estates.

Could you talk about a particular conservation success story over the course of the project?

With any luck, in the years to come the landscape-scale restoration of high altitude woodland across the Cairngorms will become a ‘textbook example’ of an effective, large-scale and long-term conservation project. This habitat, a mixture of cold and wind-stunted birch, juniper, pine and montane willow species, has been almost lost from the UK. But we are beginning to see it return at a landscape level at Mar Lodge and much more widely across the Cairngorms and Scotland. In the Cairngorms, this has been facilitated by a really nice mixture of traditional conservation work, high-tech genetics work and landscape-scale partnership working. This is still very much work-in-progress, but what’s really exciting about it for me personally is that we’re really only at the very beginning of a journey which will play out over decades. So every time I head out into the high hills I’m excited to see what I will come across.

Has documenting this project inspired you to get involved in any other long-term initiatives?

There’s a lot to choose from these days! I’m originally from the West Country, so have fond memories of the Avalon Marshes and Steart – both of which are hugely exciting projects. I’ll never forget seeing and hearing my first cranes on a very cold winter day in the Somerset Levels. But for sheer size and ambition, there are few projects more exciting than the ones currently underway in the Cairngorms.

You talk about the well-documented value of nature for our mental health, while also questioning how to facilitate the means for people to enjoy and benefit from nature without harming it in the process. Do you think eco-tourism is beneficial to conservation?

It certainly can be! There are projects across Scotland which are highlighting the benefits of eco-tourism to local economies, from the Borders to Mull to Cromarty to Sutherland. But eco-tourism isn’t a silver bullet – areas which are dependent on a single industry or land use are incredibly vulnerable to social, economic and ecological change, so it should really be seen as part of a larger solution to environmental problems, rather than a solution in and of itself. I do feel that potential impacts of eco-tourism on sensitive habitats and species can generally be mitigated through good land management practices, better education and more awareness of our own personal responsibilities towards nature. And of course, for nature to really thrive, we need to remember how to live alongside it everywhere. Why should people be content to see charismatic wildlife only on their holidays?

This is your first book, and it is a great achievement. Do you think it will be the first of many?

Right now I’m just looking forward to getting back out into the field! I’m not sure about ‘many’, but I think I’ve got a couple more books in me. And of course, I’ll have to do another Mar Lodge book in 25 years’ time to check in on progress!

Author interview with Dean R. Lomax: Locked in Time

Dean Lomax digging up dinosaurs at the Wyoming Dinosaur Center.

Dean R. Lomax is an internationally recognized palaeontologist, author, television presenter, and science communicator. He is currently a visiting scientist at the University of Manchester and is a leading authority on ichthyosaurs. He is due to publish a remarkable popular science book, Locked in Time, that looks at what the fossil record can tell us about behaviours of extinct animals by way of fifty remarkable examples. Leading up to publication, we reached out to Dean and asked him some questions.

Could you tell us a little about your background and where the motivation for this book came from?

My passion for palaeontology stems from my childhood fascination with everything dinosaur. In high school, I was not very gifted academically and my grades were not good enough to attend university so at the age of 18 I ended up selling my possessions – including my cherished Star Wars collection(!) – to help fund a trip to excavate dinosaurs at the Wyoming Dinosaur Center in the USA. That trip changed my life and formed the backbone of my career. Not only did it provide me with the necessary experience I needed to help build a career in palaeontology, but it is where the idea for Locked in Time originated. Whilst looking at the museum displays, one particularly outstanding fossil caught my eye. A trackway with its maker preserved at the very end – an animal that had literally been caught dead in its tracks. I had never seen anything like this fossil before, in books, in museums or in documentaries. This prehistoric story was preserved in time for all to see. I was hooked. It gave me that spark to discover more about prehistoric animals and their behaviours and I even ended up describing this particular fossil in the scientific literature.

In your introduction, you mention the field of palaeoethology (the study of fossils to infer behaviour). How big of a subfield is this in palaeontology? Are there specialised palaeoethologists, or is it more a case of palaeontologists contributing to this field whenever someone finds something?

Palaeoethology is a fascinating subject that allows us to explore the study of behaviours of extinct species through the evidence preserved in fossils. It is a small subfield of palaeontology, due mostly to the rarity of fossils with direct and reliable evidence of behaviours preserved. There aren’t necessarily any specialised palaeoethologists, but rather those palaeontologists who contribute to the field when something is found and described; however, palaeontologists may often be entirely unaware that they are actively contributing to the field because the idea of ethology/behaviour in the fossil record can easily be overlooked. Having said that, there are some palaeontologists that could easily add ‘palaeoethologist’ to their CVs, most notably those who work with amber which often preserve snapshots of behaviours in action. A real pioneer in the field of palaeoethology was Dr Arthur Boucot. He spent years searching for evidence of behaviours in prehistoric animals, writing numerous papers and academic monographs, and even introduced the term “frozen behaviour” for those instances where an extinct organism was preserved in the midst of some type of behaviour. Delving into his history and research was genuinely inspiring. As I have researched and published on multiple specimens and have written this book, I guess this probably qualifies me as a palaeoethologist too.

Ideas about behaviour are important to those who produce artwork depicting prehistoric lifeforms, i.e. palaeoartists. Do you find there is much of an exchange between palaeontologists and palaeoartists to try and depict behaviour in artwork according to the latest science?

The field of palaeoart has grown immensely over the last twenty years. In fact, several palaeoartists have become excellent scientists in their own right, including Bob Nicholls (the artist for this book), who has co-authored multiple scientific studies. Good palaeoartists stay informed of the latest scientific research and discoveries, with several often working very closely with palaeontologists to ensure their reconstructions are scientifically accurate. Subsequently, when based on the latest science, thoroughly researched palaeoart reconstructions are anatomically plausible. However, that said, practically all aspects of behaviour depicted in palaeoart are not based on direct evidence but assumptions. Usually, the best a palaeoartist can do is look at an extinct animal’s anatomy and environment and speculate about its lifestyle and behaviours. This is why fossilised evidence of behaviours, like those contained inside this book, are so precious and important to study and understand. These remarkable fossils tell us that prehistoric creatures were not movie monsters (prehistoric life, especially dinosaurs, are too often portrayed as roaring monsters!) but real animals that behaved in a variety of familiar and surprising ways.

What have technological advancements contributed to this line of inquiry? Are palaeontologists going back to old fossil material to reexamine them with new tools and finding new evidence of fossilised behaviour?

The use of flashy, high-tech computers, scanners and the like have helped to unlock an entirely new world of information contained in fossils. As a result, not only are newly discovered fossils subjected to this technology but much older fossil discoveries, where none of these technologies were previously available, can now be reanalysed with a fresh approach, breathing new life into old fossils as it were. This has led to some exciting discoveries of fossilised behaviours in specimens that have otherwise been deemed as having little to no research value.

Whether dinosaurs or early mammals, prehistoric organisms were faced with many of the same basic challenges as animals alive today. Has the fossil record revealed any examples of behaviours that were unique and now effectively extinct?

These types of questions are what get me excited about unravelling the mysteries of prehistoric behaviour. In many cases, “the present is the key to the past”, as geologist Charles Lyell famously introduced in the 1800s, and this definitely holds true with understanding behaviour. For example, on a basic level, we know that some groups of mammals live in herds today and that some extinct mammals also lived in herds millions of years ago (we have good fossil evidence for this). However, the natural world is filled with so many incredible acts of behaviour that you might expect the fossil record would reveal something unique. As such, perhaps one of the most unusual and apparently unique behaviours was recorded in an ancient roughly 430 million-year-old arthropod nicknamed the ‘kite runner’. The young of this arthropod were literally tethered to the parents via long spines. It appears to be the only known occurrence of this type of brooding behaviour known among fossil or living arthropods.

Rather than body fossils, past behaviour is often deduced from so-called trace fossils or ichnofossils. Nests, fossilised footprints, and trackways must be fairly easy to recognize. But what about the harder-to-identify traces? Do palaeontologists frequently encounter suspected ichnofossils where they don’t know who made them, how they were made, or perhaps even what they represent?

Yes, palaeontologists (or palaeoichnologists) frequently encounter mysterious trace fossils that are difficult or near impossible to identify or decipher. By their very definition, trace fossils represent evidence of behaviour, so we can say with confidence that an ancient animal made a nest, left its tracks or created a burrow, but they generally do not provide all of the tell-tale signs that allow us to identify what organism made it, how it was made or even what the trace might really represent. To find definite answers, we have to go a step further. In much rarer circumstances some trace fossils provide more than a ‘simple’ track or burrow and may be directly related with its maker, such that the body fossil is present inside the burrow or at the end of the track. In other examples, a track might show where the animal walked, stopped, sat down and then walked away, or a burrow might preserve evidence of scratch marks that could indicate how the burrow may have been constructed and by whom. These types of fossils provide much more information about specific moments (and behaviours) in deep time.

Were there any examples of fossilised behaviour that did not make the cut for this book but that you would have loved to include, or any noteworthy recent discoveries?

Having spent a substantial amount of time combing through hundreds of scientific papers and books, and examining specimens in museum collections, my initial plan was to tell the story of prehistoric behaviour through 100 fossils, rather than 50. It was incredibly tough selecting 100 fossils, so cutting this in half was much harder! I had to rank each of the fossils against one another, in terms of the type of behaviour, type of animal and so forth. This meant some really unusual specimens, like the aforementioned ‘kite runner’, did not make the final cut. One fossil that I would have really liked to include, and which has received worldwide media attention recently, is the so-called ‘Dueling Dinosaurs’ fossil, which appears to preserve a Tyrannosaurs and Triceratops locked in combat. I opted not to include the specimen as it has yet to be formally described, although I do make some subtle references to it. I’m very excited to see what research is revealed from this fossil, especially as only one fighting dinosaur fossil has been described, which inspired the book’s cover.

Finally, what are some of the biggest unanswered questions when it comes to fossilised behaviour? What would you love to find?

There are so many ancient groups and species that it would be easy for me to rattle off a list of some of the biggest unanswered questions about fossilised behaviour, but the reality is that we have only really scratched the surface. We have so much to learn when it comes to fossilised behaviour. After all, inferring and attempting to understand behaviour in long-extinct organisms is incredibly hard and is made even more challenging when evidence of behaviours are not preserved. It is also vitally important to remember that, by its very nature, the process of fossilisation is already an incredibly rare event, so to have any form of evidence for ancient fossilised behaviour preserved is genuinely astonishing.

Ooh, what would I love to find! I’m torn between several imaginary fossils, but if I was forced to choose one then it would have to be finding a dinosaur dead in its tracks. The thrill of following in the footsteps of a dinosaur only to find its skeleton lying at the very end of the track would be the ultimate dinosaur detective story.

Author Interview: Clive Chatters, Heathland

Heathlands are so much more than simply purple carpets of heather. They are ancient landscapes found throughout Britain that support a complex network of inter-related species and an immense diversity of habitats. They also possess a unique human history defined by the struggle between pastoralism and the competing demands of those who seek exclusive use of the land.

In this latest addition to the British Wildlife Collection, Clive Chatters introduces us to Britain’s heathlands and has kindly taken some time to answer some questions concerning this important habitat.

Heathland might mean different things to different people; how did you go about defining ‘heathland’?

Heathlands defy ready definition. The diverse places that we call heaths are cultural landscapes which are overlain with the language of ecology. It is unnecessary to reconcile these different perspectives as both traditions offer a path to understanding what makes our heathlands special.

Heathlands are one of a handful of British landscapes that have been recognised by English- speaking people for as long as we have had a written history. Sadly, many of the places that early ecologists were describing had already been depleted of much of their diversity and wonder.

This book seeks to challenge those narrow definitions and to promote an understanding of heathland that would be familiar to our forebears, as well as respecting the experience of modern people whose livelihoods are bound up with the heath.

Literature and historical accounts have addressed heaths: these landscapes can also be found in literary works, in poems and romanticised histories. When did their ecological value start to be recognised?

There is a remarkable body of literature surviving from medieval England, with many references to heathlands. Narrative poems that pre-date the Norman conquest give us an indication of how heaths were viewed by Anglo-Scandinavian story-tellers.

Heathlands at the end of the Tudor period were places where people could gather on the margins of settled society and by the seventeenth century there are the beginnings of natural histories that go beyond the enumeration of commonable livestock or illusory wild beasts. The antiquarian John Aubrey gives an account of a lichen heath in his Natural History of Wiltshire. Herbalist, Thomas Johnson published two accounts of the flora of Hampstead Heath, which include over 120 flowering plants. By tabulating a sample of these records, and ordering them by habitat association, we can gain an insight into the character of a Southern Heath in the early seventeenth century.

Throughout history there has been people who have valued heaths as a source of their livelihood. It was not until the early twentieth century that ecologists started to describe heaths and then it took many more decades before their importance to nature conservation has been expressed by conservationists. In the meantime, we have lost so much of the diversity and wonder in British heaths. What my book sets out to do is explore those riches and consider what has sustained them, where they persist.

What are your primary hopes and fears for the long-term future of Britain’s Heathland?

It is not inevitable that the catastrophic losses of the recent past are the destiny of our remaining heaths. Whilst there are still significant challenges to overcome, we know enough about these habitats to secure their place in the countryside of the future, as an integral part of British culture and home to a wealth of species that occupy ecosystems of immense richness.

If we are to rejuvenate heathland as a commonplace element in the British countryside, then we need to be comfortable with knowing what successful rehabilitation looks like. The wildlife of our richest heaths is the fortuitous by-product of millennia of pastoral farming. Over the span of human history, it has been pastoralism that has provided continuity for ecological processes pre-dating agriculture and reaching back into evolutionary time.

If we are to have working heathland landscapes, with all the advantages they bring, then the pastoralists will need to be properly funded and rewarded.

A successful heathland needs to have scale. Heathlands are landscapes that can be remarkably robust in delivering the multiple objectives that we ask of them, but they must be measured in multiples of square kilometres rather than in tens of hectares. We need not be shy about seeking to create a new generation of heaths that are large enough to serve the needs of nature alongside the ambitions of the modern age.

Heathlands are so much more than ‘just’ heathers: could you summarise their importance for a diverse range of fauna and flora?

Heathlands are a great deal more than just carpets of heathers. A heathland landscape can embrace habitats as diverse as rocks and lakes and bogs, even temporary stands of arable and wartime concrete. The component habitats of a large functioning heathland are naturally dynamic, with species dependant on all sorts of habitat formations, from bare ground to the decaying of cowpats. The great antiquity of heathland ecosystems is reflected in the network of interdependent species, many of which are associated with large herbivores, fire and occasional gross disturbance of the soil. Whilst charismatic birds and reptiles have traditionally claimed the limelight, the biological wealth of the heath is better expressed through its invertebrates, lichen and wildflowers.

Until recently, the State implemented conservation initiatives; this is no longer the case and the withdrawal of central government from practical conservation management has placed greater demands on the work of local government. Has this had a significant impact for heathland?

Heathlands are not capable of sustaining ever-intensifying levels of recreational use, no matter how benignly intended. There are numerous examples of habitats that have been degraded and species that have been lost through the complex interactions of wildlife and informal recreation. Our affection for heathlands is no safeguard against them being loved to death.

Dogs, for example, are ecological proxies to natural predators but are present at much higher densities than would occur in the wild. And large heathland ponds are frequently developed for recreation with dire consequence for wildlife.

It is reasonable for people to expect a choice as to where they can go in the countryside; regrettably, in some heathland regions, the heaths are not used for recreation as a matter of choice but because they are the only greenspaces that are available.

This is your second book in the excellent British Wildlife Collection series; the other being Saltmarsh. After all the work researching and writing that and now Heathland what is next for you? Are there plans for further books, or maybe a well-earned rest?

There are germs of ideas for future writing which I hope will take shape in the next few years. Books are daunting ventures; ‘Heathland’ summarises forty years of study and took three years to write, maybe next time I’ll look at something a little simpler.

In this latest addition to the British Wildlife Collection, Clive Chatters introduces us to Britain’s heathlands and their anatomy.

Most of our heaths are pale shadows of their former selves. However, Chatters argues, it is not inevitable that the catastrophic losses of the recent past are the destiny of our remaining heaths. Should we wish, their place in the countryside as an integral part of British culture can be secured.

Author Interview with Jeff Ollerton: Pollinators & Pollination: Nature and Society

Professor Jeff Ollerton is a researcher, educator, consultant and author, specialising in mutualistic ecological relationships – in particular, those between plants and their pollinators. Now one of the world’s leading experts on pollinators and pollination, he has conducted field research in the UK, Australia, Africa, and Tenerife, and published a huge body of ground-breaking research which is highly-cited and used at both national and international levels to inform conservation efforts. Jeff currently holds Visiting Professor positions at the University of Northampton in the UK and Kunming Institute of Botany in China.

His recent book, Pollinators & Pollination: Nature and Society, provides a hugely informative yet accessible look at the ecology and evolution of pollinators around the globe, and discusses their conservation in a world that seems to be stacked against them.

In this article we chat with Jeff about his background, the book and the future of pollinators in an increasingly changing climate.

Firstly, could you tell us a little bit about your background and how you came to write Pollinators & Pollination: Nature and Society?

Where to begin? Like lots of ecologists my interest started with natural history as a kid: poking around in rock pools, looking under stones, keeping tadpoles in jars, collecting fossils, the usual stuff that most people grow out of. I was born in Sunderland, close to the shipyards and coal mines that provided employment for most of my family. The grasslands and scrubby areas that developed on bombsites and after slum clearance were where I ranged free: my wildlife playground was the result of industrial development and decline. I also learned a lot from my dad who was a keen gardener, and plants have always been a passion. At school I didn’t do well – “easily distracted” said my reports – and only passed one A level (Biology). That was enough to get me into an HND in Applied Biology at Sunderland Polytechnic, then onto the second year of a BSc Environmental Biology degree at Oxford Polytechnic. My dissertation supervisor was Andrew Lack and he convinced me that I should apply for a PhD with him, looking at the pollination ecology, flowering phenology, and reproductive output of grassland plants in colonising and established grasslands. That was completed in 1993 (by which time the institution was Oxford Brookes University) and I went off to do some travelling and field work in Australia, funded by some small grants. When I got back I applied for numerous postdoctoral positions but the first job I was offered was a lectureship at Nene College of Higher Education in Northampton. At the time it was predominantly a teaching institution but they were keen to develop their ecological research. I originally planned to be there for a couple of years and ended up staying for 25! By that time it had transitioned into the University of Northampton. Throughout all of this the main focus of my research has been the ecology, evolution and conservation of plant-pollinator interactions, with field work in the UK, Africa, South America, and Asia. That’s a huge field of study, ranging in scope from molecular ecology to animal behaviour to agriculture and government environmental policy. A few years ago it struck me that there was a need to bring together these different strands into a single, coherent book that presented a state of the art account of why all of this was important, how the different topics fitted together, what we had learned so far after a couple of hundred years of research, and where the gaps and scientific disagreements lay. The result was Pollinators & Pollination: Nature and Society.

While it’s evident that habitat destruction and fragmentation have a huge role to play in the decline of pollinator species, you also state that rising temperatures may be a more significant factor, particularly for species such as bumblebees. Given the continual, and some may say unstoppable, rise in global temperatures, are you hopeful in any way for the future of pollinators?

Well, first of all, I certainly don’t think that climate change is unstoppable. We know what needs to be done and we know how to do it, though it’s not easy of course. But, yes, we are already seeing the effects of climate change on pollinators, particularly in relation to range shifts as insects move northwards in the northern hemisphere. Bumblebees are a particular concern because on the whole they are adapted to colder temperatures. However most other bees are adapted to warmer, drier conditions, and they may benefit from moderate climate change. The problem is that we simply don’t know enough about the natural histories of most of the 20,000 or so species of bees to say. Our knowledge of most of the hundreds of thousands of other species of pollinators is even less well developed. But I do have some optimism that pollination services to most plant species will be maintained under moderate climate change because we know from experimental work that we’ve carried out that the majority of interactions are relatively generalised and interchangeable: a range of pollinators can pollinate most plants, and vice versa. It’s the more specialised interactions that are likely to be less robust to climate change, especially in places like South Africa where I have been fortunate to work. The key to conserving pollinators, as it is for all biodiversity, is creation, restoration, linking-up, and protection, of natural habitats. As I argue in the book, we have to go far beyond “planting for pollinators” and putting up a few bee hotels if we are serious about conserving pollinators in our rapidly changing world.

While professional scientific research, alongside informed policy change, will obviously be key in directing the future of pollinators around the world, you also mention the importance of amateur naturalists and citizen scientists in collecting data and providing some of the legwork behind sustained long-term studies. What advice would you give to a non-professional individual who wishes to get involved with pollinator conservation? (eg. volunteering, donating to charities/organisations, lobbying for policy change etc.)

Yes, all of what you list there is important, and I would add that individuals can do a lot by thinking carefully about what they plant in their gardens and how they manage them (i.e. not using pesticides) and lobbying local councils about how parks and road verges are managed. They could also get involved in initiatives such as the UK Pollinators Monitoring Scheme. Similar schemes have been set up in other countries. Adding observations to iRecord is also important.

When hearing about the decline of pollinators, many people (fuelled by frequent media stories) will immediately be fearful about the future and security of our food production. Is there a valid reason for concern, and are there any precautionary steps that you believe the agricultural industry should be taking to deal with a potential collapse in pollinators?

First of all, I don’t think that pollinators are going to disappear from agricultural landscapes completely, that’s hugely unlikely. But there are a couple of things that should concern farmers and governments. There’s growing evidence that the yields of some crops, in some places, are limited by availability of pollinators, and that’s likely to get worse if pollinator populations decline. We also know that there are crops which, although they can self-pollinate, produce a higher quality of fruit or seeds if they are outcrossed by pollinators. So there’s a clear financial benefit for farmers to take pollinator declines seriously. Globally, most of the staple crops are either wind pollinated grasses (rice, wheat, etc.) or are propagated by tubers (potatoes, yams) so food security in terms of populations starving is unlikely to be a consequence of pollinator decline. However most of the fruit and vegetables that provide the essential vitamins and minerals in our diets need pollinators either for the consumed crop or, as in the case of onions, for the seeds that produce the crop. So food security in the sense of having a healthy diet is definitely something that we should take seriously. Things that farmers and the agricultural industry should be doing include the obvious such as restoring and creating natural habitat on their farms, not over-managing grasslands and hedgerows, and reducing the amount of biocides that they are using.

I discovered lots of interesting things from your book that I previously didn’t know – such as the fact that there are pollinating lizards! In all of your years of study, what is the most fascinating fact that you have learned about pollinators?

Oh, wow, that’s a tough one! Every research project that I’ve undertaken has turned up new information and observations that have intrigued and excited me, and even blown my mind. That’s one of the reasons why I do what I do, there’s so much still to discover. I estimate that we’ve got some kind of information about the pollinators of only about 10% of the 352,000 species of flowering plants that there are in the world. Even in Britain and Ireland the reproductive ecologies of most of the plants have hardly been studied. So there are always new things to discover. Citing a single fascinating fact is difficult, but if I had to choose one it would be the calculation that I made for a review article in 2017 when I worked out that as many as 1 in 10 insect and vertebrate species may visit flowers as pollinators. That did astound me and I had to double check my maths!

2020 was a year that was largely dominated by the Covid-19 crisis, a fact that you touch on briefly in your book. How has the pandemic affected your working life and, as a researcher who relies on time spent in the field, how have you dealt with the challenges of lockdown and restricted movement?

Ughh, yes, it’s been difficult. I was supposed to take a group of students to Tenerife in April for our annual field course and that had to be cancelled. It’s the first year since 2003 that I’ve not made the trip and it curtailed some long-term data collection that I’ve been undertaking. Perhaps the universe is telling me that it’s time to publish the data….? But on the plus side, once we knew that we’d be in lockdown for some months, I sent out an email to my network of pollination ecologists to suggest that we use the time to collect data on flower-pollinator interactions in our gardens. The response was phenomenal! It’s generated over 20,000 observations from all over the world. We’re writing up a paper describing the data set at the moment and we will make it freely available to PhD and early career researchers who were not able to collect data last year and whose funding and time are limited.

Finally, what are you working on currently, and do you have plans for further books?

So back in October I stepped down from my full-time professorship to work independently as a consultant ecological scientist and author – my new website has just gone live in fact: www.jeffollerton.co.uk. Although I will miss teaching students, I really needed some new challenges and wanted to work more closely at the conservation and advisory end of the field, and start to make more of a difference on the ground. I still have a Visiting Professorship at Northampton where I’m completing some externally funded projects and supervising a couple of PhD researchers. And I’ve recently been appointed Visiting Professor at the Kunming Institute of Botany in China where, vaccines willing, I will be spending part of the summer on a climate change and pollinators project. As for further books, yes, there are another three that I want to complete in the next few years. I’m talking with Pelagic at the moment about the next one and they are interested, but I’d like to keep the topic hush-hush for now – I’m referring to it as “Project B”! But it does deal with pollination, I can tell you that.

NHBS Staff Picks 2020

Welcome to our annual round-up of the books and equipment we have enjoyed reading and using this year, all chosen by members of the NHBS team. Here are our choices for 2020!

Browning Patriot

The new Browning Patriot has really impressed me this year. It is very competitively priced for a top of the range camera and produces fantastic quality photos and videos. The standout features are the 0.15s trigger speed and 0.35s recovery time between pictures ensuring you catch even the fastest moving of animals. I would highly recommend this camera for professionals and naturalists alike.

Orchard: A Year in England’s Eden

Orchards have been a traditional component of the British landscape for many centuries and their value for wildlife has long been underestimated. This passionate eulogy observes over a single year the abundant wildlife in one of the few traditional orchards left in Britain. It is a brilliantly written and informative insight into the ecological niche traditional orchards can provide and the benefit they can have for the larger ecosystems around them. Unfortunately, as in so much of the UK’s agricultural landscape, modern orchards are often deserts of biodiversity: depending on expensive machinery, pesticide controls and extensive pruning to keep competitive. However the authors make an excellent case for working with nature rather than against it, to control pests and maintain productivity that is both commercially viable and provides a haven for nature. I enjoyed this book immensely and it has inspired me to plant a couple of apple trees in my tiny back garden.

Field Guide to the Caterpillars of Great Britain and Ireland

This recent addition to the Bloomsbury Nature Guides was published in March. All throughout the first UK lockdown, I spent a considerable amount of time in the NHBS warehouse, and the book’s popularity was very visible: spotting the bright orange spine on the book trolleys and the packing benches always cheered me. This field guide is very accessible with a comprehensive introduction, a lot of detail in the species accounts, and outstanding illustrations. It’s perfect for both the novice with a little curiosity, like myself, and for experienced naturalists.
Anneli – Head of Finance and Operations

British Wildlife Magazine

I’ve loved reading British Wildlife this year, particularly the wildlife reports and columns. There’s been some amazing articles, including a recent Patrick Barkham article ‘Crisis point for the conservation sector’.
Natt – Head of Sales and Marketing

Bringing Back the Beaver

After having a previous life as a beaver researcher and seeing Derek Gow in action, Bringing Back the Beaver had to be my staff pick of 2020. Derek’s passion for beavers and nature in general really comes across and I was entertained from the first page to the last whilst being educated along the way.
Hannah – Operations Assistant

Buff-tailed Bumblebee Mug

I bought this mug and notebook as gifts for my Mum who, as a trainee beekeeper, adored them! Both products are high quality, adorable and have some lovely words about the bumblebee on it. The hand-drawn bumblebee image is detailed, lifelike and adds to the charisma of the products.
In addition to this, for every sale made, a donation is given to the Bumblebee Conservation Trust! If you are a bee lover and would like to help make a difference to conserving this enchanting species, then I highly recommend these items.
Holly – Customer Services

Hedgehog Nest Box

My pick this year is the hedgehog nest box. When an underweight and sick hedgehog had to be rescued from outside our offices this year, we were advised to place a hedgehog box out for the hedgehog’s return once she had recovered. The Hedgehog Nest Box was an obvious choice, being sturdy, well-designed and tested extensively by the Hedgehog Preservation Society. The in-built tunnel ensures inhabitants are kept safe from draughts and any unwanted visitors, and the removable lid meant we could fit a nestbox camera inside the nesting chamber to keep an eye on the recently recovered hog.
Antonia – Deputy Wildlife Equipment Manager

1080p HD Wired Outdoor Bird Feeder Camera

I love being able to see the wildlife in my garden but never want to scare any of it away and this little camera is a great solution to that problem. It allows you to live stream footage in full HD straight to your TV or monitor, day and night. It is small enough to fit into a nest box and watch the “behind the scenes” of the start of garden birds’ lives, or the comings and goings of hedgehogs from their daytime refuge in a hedgehog box. But on top of that, with this camera’s completely weatherproof casing, it can be used outside of nest box season to watch feeders in the garden or small mammal highways with no additional protection.

Aquapac Trailproof Daysack

Despite having only a ten minute walking commute to the office here in Totnes, the inclement winter weather means I have to be well prepared if I want to arrive dry and warm! That’s why my pick this year is the Aquapac Trailproof Daysack. Its all-welded construction and roll top seal make it a thoroughly reliable waterproof pack. I’ve used it for a variety of purposes, from wet weather running and hiking and even loading it with groceries! It’s 500d vinyl construction makes it a very rugged pack for day hikes and the padded straps mean it can hold a surprising amount of weight whilst remaining comfortable. If you’re looking for a versatile hard-wearing dry pack then this is it!

Owls of the Eastern Ice

Owls of the Eastern Ice is a spellbinding memoir of determination and obsession with safeguarding the future of this bird of prey that firmly hooked its talons in me and did not let go.
Leon – Catalogue Editor

Batbox Duet Bat Detector

Having worked as a freelance bat surveyor for a couple of years now, I can say that the BatBox Duet is by far my favourite entry/mid-level bat detector on the market. The main reason for this is that it enables me to simultaneously monitor calls via frequency division – meaning that a bat calling at any pitch will be heard in real time – and heterodyne feeds, affording me a rough idea of which species I’m listening to. It is robust and easy to use, and comes with BatScan pro, a comprehensive analysis program that allows recorded calls to be studied later. With an affordable price to boot, this detector is always an easy recommendation for those looking to advance their bat knowledge.

Author interview with William Eberhard: Spider Webs

Behavioural ecologist and entomologist William Eberhard is an emeritus scientist at the Smithsonian Tropical Research Institute in Panama and emeritus professor at the Universidad de Costa Rica. His research interests include sexual selection, evolution, and animal behaviour, and one group of organisms he has worked on in particular is spiders. Based on half a century of study, Spider Webs is an unprecedented and very large book on their biology, evolution, and diversity. Leading up to publication, we dipped into the book and asked him some questions.

As I was reading your book, it seemed all the spiders in my garden were out to build webs and I found myself barred from reaching my laundry one morning. How bad should I feel for accidentally destroying a web?

Out of consideration for my fellow inhabitants of the Earth, I always walk around webs rather than through them. But that is my own idiosyncrasy. Many spiders make a new web every day, so having a web knocked down is not a big disaster. Some move away from sites where their webs have been destroyed, so you might decide where to walk, depending on whether you do or do not want the spider to stay at the same site.

Spider webs are marvellous contraptions, even more so when you realise how they are made. You explain how spiders are virtually blind to their own web lines and that webs are often built at night. This implies an important role for tactile senses. Yet, construction starts by floating so-called bridge lines to distant objects, suggesting a role for vision. How good is spider eyesight and how much do we know about their visual acuity?

Eyesight has little and probably nothing to do with their floating bridge lines. Casting those lines down the wind constitutes a blind bet that maybe there is some object there that they will snag on.

You point out that the majority of published behavioural observations have been of mature females. What do we know about males and immature spiders? Is web construction specifically a female activity? Or have we just not looked hard enough?

In most spider families, mature males dedicate themselves nearly strictly to sex –finding receptive females is probably a tough job. They stop making prey capture webs and lose the glands that made the sticky silk in these webs. They also stop eating, except, in a few species, in which males occasionally temporarily appropriate a web from a smaller, immature individual. Immature individuals, both male and female, make webs.

A web is built from various different kinds of silk, and different parts have different functions, from structural support to prey capture. How do spiders control what kind of silk they release, especially given that some species can build a complete web in as little as half an hour?

Presumably valves in the ducts of different types of silk glands open or close to control which types of silk are extruded from the corresponding spigots. Even in a given orb, the kinds of silk that are used to cement lines together are turned on and turned off hundreds of times in an extremely precise manner during the construction of a single web.

You mention that orb webs are neither the pinnacle of web evolution nor necessarily the optimally designed structures that they are often claimed to be. Most organismal traits are a product of history and contingency as much as natural and sexual selection. I might be asking you to speculate here, but, in your opinion, are there any particular evolutionary thresholds that spiders have not been able to cross that would make a big difference for web construction?

There is a small section in the book (Section 9.8) where I discuss web designs that are possible but that have not arisen in spiders. In general, they have used radial rather than rectangular arrangements of lines; I do not know whether the widespread adoption of and ensuing variations on rectangular arrangements would have made a big difference or not.

Do you find that technological advances have changed the way arachnologists work and the sorts of questions they ask?

Yes, very much so. Important techniques that have begun to be used and that have produced new kinds of data during my lifetime include electron microscopy (especially scanning electron microscopy), molecular comparisons to produce phylogenies, digital movies, virtual sections (“micro-CT scans”), and large scale, computerized data analysis. At the same time, fads for using these techniques have led to less frequent use of simpler but powerful types of observations such as study of the details of behaviour.

Producing a book of this scope must have been a tremendous job, and you remark that a thorough, book-length review of spider webs had yet to be written, despite more than a century of research on spiders. With the benefit of hindsight, would you embark on such an undertaking again?

I seriously underestimated how difficult it would be. I had written two books previously, both largely concerned with ideas, rather than being attempts to review previous work as was the case in this book. My previous experience did not prepare me for the challenges of reviewing and evaluating – and in some cases arguing against (hopefully sympathetically and constructively) – conclusions from previous work.

You mention this book’s coverage is inevitably idiosyncratic. What lacunae remain in our knowledge that future authors could fill with further work?

My major deficiencies are in the chemical and mechanical aspects of silk – a field that is currently very active and that will undoubtedly eventually (perhaps soon) result in book-length treatments. A second major blank space that I hope will be filled with future work is linking web construction behaviour to the slowly emerging but very important field of animal cognition. The many advantages of orb webs for studying the details such as errors and other difficult questions in the behaviour in animals whose behaviour has a major innate component (and probably little in the way of learning) have yet to be exploited.
