Author Interview with Peter Holden and Geoffrey Abbott: RSPB Handbook of Garden Wildlife

Now in its third edition, the RSPB Handbook of Garden Wildlife is a comprehensive and inspiring guide to making the most of your garden for wildlife. Full of practical tips, the book provides information on what plants to grow and how to structure your outside space to make it as attractive as possible for garden species, including mammals, birds, insects, invertebrates, reptiles and amphibians. A DIY chapter includes lots of projects such as nest box building and making your own pond.

There is also a comprehensive species account section which includes information and colour photographs of almost 400 garden species, helping you to take stock of the wildlife that is present in your garden, and to monitor how this changes over time. The third edition of the RSPB Handbook of Garden Wildlife also features new material on climate change, recycling and encouraging wild spaces in gardens.

Peter Holden is the author of the bestselling RSPB Handbook of British Birds. He held senior positions at the RSPB for over 30 years and is the author of several books. Geoffrey Abbott formerly worked for the RSPB and now lectures part-time for the Field Studies Council. He is responsible for the book’s plants and insects sections.

In this Q&A we chatted with Peter and Geoffrey about the book, about the importance and benefits of keeping our gardens ‘wild’ and their recommendations for small but impactful changes we can make in our outdoor spaces.

Now in its third edition, it has been 14 years since the first Handbook of Garden Wildlife was published. Do you think there have been significant changes in terms of types/styles of gardens and the wildlife they support during this time?

Geoffrey: there is now even more pressure on natural habitats and wildlife, and a continuing decline in many species such as bees, Starling and House Sparrow. This means that gardens are of even more value for conservation. At the same time there are more new houses, with smaller, or no gardens, and a continuing trend (as David Lindo so graphically points out in his foreword) to cover gardens with concrete or paving. There are also changes in our gardens due to the arrival of new species, some perhaps due to climate change. We have included some of the species (like Ivy Bee and Tree Bumblebee) that you are most likely to see in your garden.

Peter: Gardens will also be affected by changes in climate, especially if we have drier summers so we have introduced a new chapter on dry gardens.

In the book, you recommend keeping a log of the wildlife observed in a garden over the year. Do you think that this has become something of a lost art – taking the time and having the patience to observe the same bit of land over time and enjoying the process of noting the changes?

Peter: Yes, I see fewer people using a notebook and pencil when out birding and they don’t seem to be recording on mobiles either, even though there are excellent Apps like the BTO’s Birdnet. It should be easier than ever to keep notes at home using electronic spreadsheets and diaries. With programmes such as iRecord you can input photos and sightings and have the satisfaction of knowing these records are added to local and national databases – helping to build up a picture of changing wildlife populations.

In the introduction, you mention how important our gardens became to us during the Covid-19 lockdowns of 2020 and 2021. Improving them for the local wildlife has obvious benefits for conservation, but do you think there are also benefits from making these changes for ourselves and for our children?

Peter: There is more and more evidence showing environmental benefits on wellbeing and general health. There are also the additional benefits of exercise that comes from gardening and opportunities for relaxation. However, best of all, I see gardens being the ideal place for small children to start to learn about nature. It might be watching an ant’s trail, planting wildflowers, feeding the birds or helping to prepare a small pond, making pitfall traps for bugs or doing the Big Garden Birdwatch. And it’s not just parents – grandparents are often the ideal teachers for the next generation – with more time to share their own knowledge and experience.

In the section of your book on wilding, you describe the ideal garden as ‘organised chaos’. Do you think that the current trend for neatness and tidiness in a garden can be problematic in terms of attracting wildlife?

Geoffrey: Absolutely. Just one example is clearing all the dead heads from the borders which removes important food sources in the form of seeds, for birds and small mammals. Hollow dead stalks are also important sites for many hibernating insects. Tidying beds of leaf litter removes a whole community of invertebrates, and important feeding sites for thrushes, Blackbirds and Robins. Colonies of House Sparrows love scruffy corners and dense shrubs, while a pile of prunings and dead leaves can even provide a hibernation site for hedgehogs and a home for beetles and other invertebrates. Converting part of the garden to concrete or paving, or even replacing a lawn with Astroturf for easier management, will make whole areas sterile of wildlife.

One part of the book that I found particularly useful was the section on seasonal management, which also includes a handy monthly guide to the wildlife you might see and the tasks that need to be undertaken. How much would you say that maintaining a garden for wildlife differs from more ‘conventional’ gardening techniques?

Peter: That is an interesting question as there is not really a right or wrong way of doing things. It’s really about empathy – understanding your garden environment and gradually moving it from a homocentric place to one where wildlife is the focus. Every action will have nature in mind, while still keeping the garden as our own special place – it’s a delicate balance…and its fun…and over time our knowledge will grow as well.

For any readers with an average sized urban or suburban garden who wants a quick and affordable change that they can make, what would you recommend as something impactful but achievable that they could begin with?

We are both agreed that by far the best single improvement is to create a pond.

Geoffrey: This will greatly encourage garden wildlife by providing a source of water (for animals such as bees, birds and hedgehogs), mud for nesting birds, and a variety of extra insects as food. The pond will also add a whole new community of creatures, many of which leave the water at the adult stage. You may encourage frogs, toads or newts, as well as insects such as dragonflies and damselflies. These can give a whole new dimension to the summer garden.

Peter: A pond need not be large or complicated to make. A simple moulded plastic or flexible liner will suffice. It needs to be deep enough not to dry out but have some shelving edges to allow birds or hedgehogs to drink. However, avoid introducing fish – they are incompatible with most other wildlife in a garden pond.

Finally, what are you working on now? Do you have plans for further books?

Geoffrey: I will be writing wildlife notes for local magazines.

Peter: I will continue to work on updates for future editions of this Handbook and also for the RSPB Handbook of British Birds. I will continue with lectures for RSPB local members’ groups and hope to meet some of you there!

RSPB Handbook of Garden Garden Wildlife by Peter Holden and Geoffrey Abbott was published in February 2023. It is published by Bloomsbury Publishing and available from nhbs.com.

Author Interview with George Peterken: Trees and Woodlands

Written by one of the UK’s most highly regarded forest ecologists, Trees and Woodlands weaves together personal stories and scientific research in a thorough exploration of our woodlands, their ecology and how we as humans have interacted with them over the course of history. The 12th installment in the popular British Wildlife Collection, Trees and Woodlands will appeal to anyone who is fascinated by the stories told by our native woodlands and who is invested in their future.

George Peterken worked with the Nature Conservancy to start the ancient woodland inventory and later worked as nature conservation adviser at the Forestry Commission. His research interests, which have centred on nature conservation, natural woodland and long-term and large-scale aspects of woodland ecology, benefited from a Bullard Fellowship at Harvard University. He is the author of a large number of books on both woodlands and meadows and was awarded an OBE for services to forestry in 1994.

In this Q&A we chatted with George about the book, about his life and career as a woodland ecologist and about his hopes for the future of woodlands in the UK.

Firstly, can you tell us a bit about yourself? How did you get into working with and researching woodlands?

All my childhood holidays were visits to my Mother’s family on the edge of the New Forest and the woods at Ruislip and the Chilterns were my targets as a teenage cyclist, but woods became fully imprinted with 6th form natural history camps at Beaulieu Road in the New Forest, led by my charismatic teacher, Barry Goater. I gained an entry to woodlands research when Palmer Newbould at University College, London, accepted me as a PhD student to study New Forest woodlands on a Nature Conservancy grant. Then I had the luck to be offered my ideal job as a woodland ecologist at the Nature Conservancy’s Monks Wood Experimental Station. This was a madly exciting and committed place to work where, as you will see from the book’s dedication, we thrived on the freedom we were allowed. Thereafter it was necessary to ride out the constant reorganisations thrust upon us by our paymasters, the Government.

Trees & Woodlands is a wonderfully wide-ranging book. I particularly enjoyed the frequent stories and anecdotes from your own life and career, as well as the well-researched snippets of history, culture and language. Does the human-landscape interaction interest you?

Certainly. Its much more entertaining to explain what I find in a wood in terms of human actions and unforeseen consequences than in terms of soils, climate or some other natural factor. It was Colin Tubbs who taught me this when I was a research student and he was the Nature Conservancy’s warden-naturalist for the New Forest. We would notice some feature of the vegetation distribution or woodland structure and find, more often than not, that we could understand it best as, say, an abandoned extension of agriculture or an unexpected consequence of an Act of Parliament regarding deer. Then at Monks Wood, I found that Max Hooper and John Sheail in particular were just as keen as myself to study ecology in a county record office as we were in the fields and woods. Then, of course, we all came across Oliver Rackham who had seized on the same links between history and habitats. He more than anyone has demonstrated that it’s the human element that generates most interest in the natural world. This interest also had direct benefits for my main work in woodland nature conservation: it was much easier to negotiate management that benefited nature with a woodland owner who had a keen interest in the history of his/her wood.

Your book in large part looks at the interaction between humans and woodlands over the course of history, both ancient and recent, and you state that we would have to go a long way back in time to find a woodland which was not modified by the presence of man. Where in the UK would you say is closest to a ‘natural’ or ‘unmodified’ woodland, ie one that has been affected the least by humans?

This is the subject of one of the chapters. Spending my career working with semi-natural woodlands, I spent a lot of time wondering what natural woodland looked like, then, as you can read in my contribution to Arboreal (Little Toller, 2016), came to the conclusion that natural woodland takes many different forms, but that no woodland existing since the last Ice Age could be entirely unaffected by people. We can witness approximations by allowing an ancient, semi-natural woodland to grow without direct management intervention – which is what we have studied at Lady Park Wood – or by ‘shutting the field gate’ and watching what happens as shrubs and trees invade. Whether the results look like pre-Neolithic woodland, which harboured large herbivores, is a subject that has animated woodland ecologists in recent years: some would say that the New Forest is natural in that sense, even though it has been used and managed for centuries. ‘Natural woodland’ to the general public means ‘woodland of native trees not obviously managed’ and I think ecologists should get close to that.

Extreme weather events such as storms and flooding are likely to occur at an increased frequency due to the effects of climate change. Coupled with the anthropogenic impacts of deforestation, land use change and overgrazing, this might seem to paint a dim picture for the woodlands of the future. Moving forwards, what do you think are going to be the main challenges in the UK when it comes to preserving and improving our native woodlands?

The immediate threats come from novel diseases and pests, uncontrolled deer populations and our limited ability to sustain low intensity management, which leads to neglected woods becoming less stable and losing some elements of their biodiversity. Pervasive eutrophication via rain seems to reinforce the biodiversity losses from unmanaged woods.

Deforestation is not really a problem here; storms would have less impact if woods were managed and thus stand ages were younger; trees and woods are part of the solution to flooding; and the main immediate danger from climate change may be a form of self-fulfilling prophesy when, say, beech stands are felled and replaced by introduced species that we think will better withstand future climates. Ancient woods seem reasonably well protected by public opinion, the Woodland Trust and official organisations, but we could easily drop our guard if we again believe – as we did around 1970 – that all these new woodlands will form an adequate replacement.

In terms of woodland management and the policies which govern this, what changes would you like to see in the UK over the coming years?

I’m now way out of the loop of forestry politics, but I can answer in more general terms. Throughout my career foresters have been itching to bring the now neglected former coppices back into management. Most of these are ancient woods and therefore important for nature conservation, so I took the view through the 1970s that they should be left alone, or coppiced, since their likely fate under forest management would have been planted conifers. But from 1982, when what became the Broadleaves Policy was under discussion, I advocated management based on site-native tree species, and I have not changed since. We must find or generate markets for native tree timber and wood, like Coed Cymru did and does, that would benefit wildlife and give more people a stake in the future of ancient woodlands. I like the idea of more community involvement, but in practice this usually comes down to one or two individuals. I am all in favour of leaving a representative selection of woods to grow naturally – limited intervention, or none – partly because they will act as a constant reminder of the benefits of management.

Since you began working in and researching woodlands, have there been any major technological advances that have had a signification impact on the type and quality of research that you do?

Linking my name with technological advances will elicit hollow laughter in some quarters. For years, my fieldwork has involved pencil, paper, girthing tape and metal plot markers. I have tried GPS to mark plots, but in the woods I’ve studied the errors are too large to find small plots. I do use a spreadsheet to analyse the records, though. My research started when statistical analyses were undertaken long-hand on an electric machine that whirred and juddered for ever while it did long divisions, so the arrival of computers, the internet and digital cameras is obviously the key technical advance. This has enabled astonishingly intricate analyses of huge volumes of fieldwork data, but it has also led to papers in, say, the Journal of Ecology becoming unreadable. The need now is to present and explain research results and their implications to as wide an audience as one can summon in a form that can be appreciated by a general readership. Technical advances are important and often amazing, though nothing like as important as developing the skills to write clear, accurate, non-technical, substantial and readable text. I like to think that British Wildlife magazine and the derivative Collection of books have shown the way.

Finally, what’s next for you? Do you have plans for further books?

I’m reaching the age when plans are futile, but I still like to have an on-going project. On books, I am helping Stefan Buczacki write about Churchyard Natural History. One of the most rewarding of recent projects was my collaboration with a group of professional artists, The Arborealists, in Lady Park Wood (Art meets Ecology, Sansom, 2020) and we have plans for a sequel in Staverton Park, a Suffolk wood-pasture I knew well in the late 1960s. For several years I gave up woodlands and took a close interest in meadows, which led to an earlier book in the British Wildlife Collection and gave me an enthusiasm for wood-meadows, so I’m doing what I can from a distance to help the Woodmeadow Trust.

Trees and Woodlands by George Peterken was published in February 2023. It is published by Bloomsbury Publishing and available from nhbs.com.

Author Interview with Susan Young: Wildlife Photography Fieldcraft

This unique book describes a straightforward system for how to successfully locate wildlife, the most difficult aspect of wildlife photography. Photographing the stunning natural world around us can be a challenging process. Not only does getting the perfect shot require a complex mixture of skill and luck, but there is little practical advice available on how to find the wildlife you’d like to photograph. While patience and persistence have to come from you, being equipped with the right fieldcraft knowledge, offered in this book, can increase your chances of getting the results – and the special moments – you are looking for.

Individual chapters offer guidance on how to photograph birds, mammals, butterflies and dragonflies, as well as reptiles and some of our more elusive species. Various habitat types are discussed, along with tips on equipment, technical specifications and guidance suitable to both newcomers and more experienced wildlife photographers. While sharing some of her most successful and beautiful images, Susan Young also gives useful examples of when things didn’t quite work out – reflecting on how things could have been done differently to get a better outcome.

Susan Young speaks with us about why she chose to write this book, her process for researching each chapter and why wildlife photography is so important for engaging the public with the environment and conservation.

Your new book, Wildlife Photography Fieldcraft, is a unique guide to how to successfully locate wildlife. What drew you to wildlife photography and why did you choose to write this book?

I have had a keen interest in nature from an early age. I originally took up (digital) photography for landscapes, but it was a natural progression to wildlife photography so I could keep a record of my finds. When I started with wildlife, I found it very difficult to find suitable subjects, especially the less common ones, and of course many mammals are nocturnal. I studied many books on wildlife photography, but they all seemed to concentrate on photographic techniques and gave little or no information on how to find wildlife. I had written books before on subjects not previously covered, so decided to write the book I wished I had been able to find when I was looking.

You mention in this book that a lack of knowledge on how to find wildlife to photograph may be just as risky as providing too much information, could you expand on this?

This is related to disturbance. If photographers know very little about the subject of their photographs and do not understand the sensitivity of wildlife, they could disturb a bird, for example, and cause it to abandon its nest, or frighten a deer so it runs off and becomes injured.

On the other hand, if too much information is given out, particularly of a detailed location, photographers can flock to the area in large numbers. This has happened with rare birds, for example, and the birds have become very distressed.

This guide is broken up into chapters covering different species groups, all of which are richly detailed, covering descriptions, diet, breeding, habitats, population estimates and more. What was your process for researching the different chapters, and why did you choose to go further to cover topics such as how to make a portable hide and thermal and dynamic soaring?

The whole focus of the information was on what factors influenced where, when and how to find wildlife. Population estimates and habitats, for example, influence where the subject might be found in a broad sense. Breeding and its rituals have a great effect on when certain species are most active and thus most likely to be seen. Description, diet and habits are more detailed indicators allowing the photographer to fine-tune the search, for example. Goldfinches like thistle seed (diet), they are often in flocks (habits) and have distinctive colouring (description), so a photographer situated near a patch of large thistles, at the right time of year, could have interesting photographs of goldfinches balancing on thistles and interacting with each other.

My process was to think of each category for different species and, based on my experience, record the facts for each species and describe how to use them to find wildlife. I then studied reliable sources to add further detail and confirm that what I already had was accurate.

Hides are extremely valuable as they allow the photographer to get close to nervous or rare species without disturbance. Portable hides are particularly useful. I found it difficult to get a flexible, sturdy, inexpensive portable hide that would be comfortable if sat in for some time. My design was based on the plastic pipes I had seen on an American trip, and can be tailored to the individual very easily, and is strong but not too heavy.

Photographing birds in flight, especially birds of prey, is very difficult. By understanding thermal and dynamic soaring, the photographer is equipped to predict the best position to photograph a bird in flight i.e. when the bird is moving more slowly and at the correct height.

How important do you think wildlife photography is in increasing public engagement with the environment and conservation?

Wildlife photography is hugely important as photographs can convey an emotion or fact better than words, and in particular can illustrate features or situations in a compelling, thought-provoking way, or simply attract by their beauty.

Your case studies provide a wonderful insight into your photography process. Are there any species that you haven’t yet photographed but would love to?

Pine Martens are at the top of the list. They are beautiful and intelligent but, at present, rare in England. Beavers are another species I would like to photograph, and hopefully, this will become easier if they are introduced to other parts of the UK.

Do you have any current or future projects that you would like to tell us about?

At present I am developing interactive online mini-courses for the Mammal Society using photographs, videos and interactive features. The aim is to attract and engage with more people to gain their support in the quest to learn more, and use the knowledge to try to halt the decline of UK wildlife. I am also developing a course to encourage the use of CCTV systems to monitor wildlife.

Author Interview with David Shiffman: Why Sharks Matter

Sharks are some of the most fascinating, most ecologically important, most threatened, and most misunderstood animals on Earth. In Why Sharks Matter: A Deep Dive with the World’s Most Misunderstood Predator, marine conservation biologist Dr David Shiffman explains why it’s crucial that we overcome our misconceptions and rise above cinematic jump scares to embrace sharks as the critically important species that they are.

Exploring the core tenets of shark conservation science and policy, Shiffman synthesises decades of scientific research and policymaking, weaving it into a narrative full of humour and adventure. Approachable and informative, Why Sharks Matter is perfect for shark enthusiasts, explaining why sharks are in trouble, why we should care and how we can save them.

Dr David Shiffman recently discussed his new book with us, explaining how he became fascinated with sharks, what is being done to change public opinion and why social science research is so important to shark conservation.

Firstly, could you tell us how you became fascinated with sharks and the inspiration behind this book?

I’ve loved sharks for as long as my family can remember, there are pictures of me when I was barely old enough to walk with shark t-shirts and shark toys. I think most kids go through a shark thing or a dinosaur thing, and I never grew out of mine. When I give public talks, inevitably someone will come up to me afterwards and say “I wanted to be a marine biologist when I was a kid”- and I always reply “Me too!”.

In my experience speaking to the public, I’ve realized that lots of people want to help sharks, but don’t necessarily know the most effective ways to do that. And while there are lots of shark books out there, there was nothing that comprehensively lays out the case for having healthy shark populations off our coasts, systematically reviews the different threats to shark species, and thoroughly reviews the different ways that scientists, environmentalists, and the public can help sharks. In short, I wrote the book that I always wished existed, because I know there’s a need for it.

The book does an impressive job of debunking the public image of sharks as dangerous and violent predators. Outside of your own work, what is, if anything, being done to change public opinion about sharks?

As a marine conservation biologist who studies sharks and how to protect them, I know that we need the public to not only no longer fear sharks, but to value the role they play in the ecosystem and to want them around. And I also know that it matters what people do to help, and that there are lots of things that people do while trying to help that are not really helping. I use this book as a chance to bust some myths not only about sharks as mindless killing machines, but also myths about threats to sharks and solutions to these conservation challenges. The subtitle doesn’t call them “the world’s most misunderstood predator” for nothing! In the book, I introduce readers to some of my favourite environmental non-profits who are working to educate the public and persuade policymakers that we need new and stronger laws. If you’re looking for good groups to support, I am happy to recommend them to you.

What do you think is the biggest threat to sharks and what can the average person do to help?

The science is clear on this point: the biggest threat to sharks is unsustainable overfishing, including but not limited to the shark fin trade (which many well-intentioned shark-o-philes wrongly believe is that only threat to sharks). The single most effective thing that an individual consumer can do to help not only sharks but the whole ocean is to not eat unsustainable seafood. Notice that I did not say “give up all seafood and become vegan,” because while that’s a perfectly valid personal choice, the people claiming that we all need to do this or the oceans are doomed are not telling the truth. If you, like me, love seafood, just choose to buy sustainable seafood.

You share a range of scientific tools used to monitor sharks, from eDNA to telemetry tracking, but you also highlight the importance of social science research. Why do you think this approach is important to shark conservation?

A major goal of the conservation movement is passing new laws or regulations to protect endangered species, but notably these laws do not limit what the animals can do, they only control humans. Therefore, we need to understand what humans want, what humans do, and what humans know–and these are questions that the social sciences are designed to answer.

What is your vision for the future of shark conservation? Are you hopeful or pessimistic?

I am cautiously optimistic about the future of the ocean. More people care and want to help than ever before, and if we can channel that energy into something productive, we can move mountains!

And lastly, do you have any current projects or plans for the future that you would like to tell us about?

I’m always on the move, always up to some new project. If anyone would like to follow my adventures, or to ask me anything you want to know about sharks, I invite you to follow me on Facebook, Twitter, and Instagram @WhySharksMatter.

Author Interview with Mark Carwardine: Field Guide to Whales, Dolphins and Porpoises

Practical and portable, this is the ultimate field guide to the world’s cetaceans. This is the most comprehensive, authoritative and up-to-date guide to whales, dolphins and porpoises. Containing more than 500 accurate illustrations – complete with detailed annotations pointing out the most significant field marks – this new field guide covers all 93 species and every subspecies in the world.

The informative text, produced in collaboration with many of the world’s most respected whale biologists, is accompanied by distribution maps, size demonstrations, dive sequences and additional information such as comparisons of silhouettes and illustrations of barnacles, lice and callosities.

Cetacean expert Mark Carwardine kindly took the time to discuss this new field guide with us, discussing how the outlook for cetaceans has changed since he first began to study them, why he chose to use illustrations over photographs and what he is working on now.

What inspired you to write this new field guide and how does it differ from your previous handbook?

The Handbook of Whales, Dolphins and Porpoises was the culmination of a life’s work, really, and took six years to research and write. It was designed as a comprehensive reference book to be used at home or in the office – and, consequently, weighs almost as much as a small porpoise. The pocket-sized Field Guide to Whales, Dolphins and Porpoises is an abbreviated (and fully updated) version, focusing more on identification, and it has been designed specifically to take into the field. Since our knowledge of cetaceans has improved so much, with new behaviour and many new species described in recent years, previous field guides (my own included) are drastically out of date. I think a new guide was desperately needed.

Your book includes a number of threatened species, including the functionally extinct Yangtze river dolphin and the vaquita, many of which we may lose entirely over the next decade. How has the outlook for whales, dolphins and porpoises changed since you first started to study cetaceans?

There’s no doubt that for many cetacean species, if not most, the outlook is worse than it was when I started working in this field. Some – the humpback whale is a good example – are doing surprisingly well, against all odds. But many others are not. The vaquita, we believe, is down to the last 10 individuals and is almost certainly the next (after the Yangtze river dolphin) doomed to extinction. Sadly, though, it’s not alone. The North Atlantic right whale comes to mind – there are fewer than 350 survivors and, with numbers continuing to decline, we fear for its future. Countless others are on the verge of extinction or have all but disappeared from many of their former haunts. Sometimes, I am surprised that any survive at all, given the shocking number of threats they face, such as commercial whaling and other forms of hunting, myriad conflicts with fisheries, pollution, habitat degradation and disturbance, underwater noise, entanglement in or ingestion of marine debris, ship strikes and climate change.

This field guide is full of beautiful and detailed illustrations. Why did you choose to include these rather than photographs?

I prefer the use of illustrations in field guides, because I think they demonstrate the key identification features more effectively. Also, there is a huge amount of variation within each species of cetacean – geographical variations, races and sub-species etc – and good photographs do not exist of many of the most critical ones!

Relatively little is known about the population estimates or trends of many of the species listed in this book. Why do you think this is the case, and is there ongoing research taking place to fill these knowledge gaps?

It’s true to say that our knowledge of cetaceans has grown from virtually nothing to just a little bit – despite decades of wild whale research. They are incredibly difficult animals to study, because they spend most of their lives underwater, often live far out to sea and regularly travel vast distances. They are even more difficult to count. I take people to see the friendly grey whales in San Ignacio Lagoon, Mexico, every year and we have fun trying to estimate the number of whales within the relatively small lagoon. Everyone comes up with wildly different numbers. Just imagine trying to estimate the number of minke whales, for example, in the North Atlantic. In some cases, a species is so rare that we know every individual and have an accurate population size. But in many cases it’s an informed guesstimate. The key thing is to be able to compare these guesstimates from time to time and place to place to get relative population trends. And, with some exceptions, I do think we have a pretty good idea about which species are declining and which are doing relatively well.

Is there anything that you are currently working on or do you have any plans for future projects that you would like to tell us about?

Well, I’ll never stop spending as much time with whales, dolphins and porpoises as possible! And I’ll be keeping the field guide up-to-date, of course, for future editions. But I’ve also been working on a book closer to home, called RSPB How to Photograph Garden Birds, which will be out early next year (to tie in with the RSPB’s Big Garden Birdwatch). It started as an excuse during lockdown to photograph my own garden birds but, as I developed and discovered more tricks and techniques, it gradually turned into a book. One thing I’ve learned is that you don’t have to travel to far-flung corners of the world to take great pictures of wildlife. Indeed, some of the most memorable and eye-catching images I’ve ever seen – especially while judging umpteen wildlife photography competitions over the years – have been of common and familiar species taken close to home. Yet these more ‘ordinary’ subjects tend to be ignored by many photographers. They are considered too obvious or insufficiently compelling (although I’ve never understood why because, by any standard, many of our garden birds are strikingly beautiful). While there are countless awe-inspiring images of polar bears and humpback whales, when was the last time you saw a truly inspirational image of a house sparrow or a robin, for example? Exactly. Hopefully, that’s where this book will help and inspire.

Author Interview with Nicholas Milton: The Secret Life of the Adder: The Vanishing Viper

In 2019, the most comprehensive survey ever of adders was published. According to ‘Make the Adder Count’ the species will disappear from most of Britain in the next 15-20 years unless we take action now. But despite being a priority conservation species under the Biodiversity Action Plan, not a single nature reserve in Britain has been specifically designated to protect adders. The Secret Life of the Adder contains a 10-point action plan which, if implemented, could help to restore the adder to its former range across Britain. With a foreword by BBC’s Iolo Williams, this book is a story of our time, one which typifies the age of extinction through which we are all living and are all responsible.

Author Nicholas Milton recently took the time to discuss his new book with us, explaining the inspiration behind it, his opinion on current ecological guidelines and his advice to naturalists that might want to get involved in reptile monitoring.

Could you tell us a bit about your background and what inspired you to write The Secret Life of the Adder: The Vanishing Viper?

I graduated with a degree in Environmental Science in 1989, and then worked in the environmental movement. My first job was with the RSPB and afterwards I worked for the Farming and Wildlife Advisory Group (now sadly defunct), The Wildlife Trusts and Greenpeace. I’ve been fascinated by adders since childhood and at the RSPB I was lucky enough to spend time with the late Ian Prestt. As well as being the Director of the RSPB, Ian was also a leading authority on adders (his M.Sc. was on vipers as he liked to call them). Every week we would go looking for adders and he taught me a lot about them. Sadly, Ian passed away in 1995 and since then the adder population has crashed. This was confirmed in 2019 when the most comprehensive survey ever of adders was published. ‘Make the Adder Count’ showed that the species will disappear from most of Britain in the next 15-20 years, so I decided that in Ian’s memory I had to do something about it. The book is my attempt to conserve the species using a 10-point adder action plan, and wake up the government, its nature conservation agencies, the media and the public to its plight before it is too late.

As well as authoring this book, you work as a freelance journalist for a variety of publications. Among your work are articles promoting the conservation and public image of the adder. How have you found the reception of such pieces?

It’s not easy to make the case for a venomous snake in Britain because we live in a small and crowded island with increasingly little space for wildlife. Every year there are a plethora of completely irresponsible adder ‘horror’ stories in the media which reinforce the mistaken impression that the adder is a dangerous species. No one has died from an adder bite in over 40 years and these stories rarely, if ever, mention that the species is on the verge of extinction. In reality the adder is a shy and sensitive snake which will always avoid interaction with people unless it is molested. The good news is attitudes towards adders are slowly changing, spearheaded by organisations like the Amphibian and Reptile Groups of the UK and the Amphibian and Reptile Conservation Trust who do fantastic work telling people about how wonderful adders are and conserving their remaining colonies.

There are many beautiful photographs in The Secret Lives of Adders, a notable majority of which have been taken in-situ. This is in contrast to images in many other herpetological titles. What were the reasons behind this decision?

I can’t claim credit for most of the images in the book which were taken by the photographer Roger McPhail. He very kindly donated them for free as he wanted to help conserve the species. By being taken in-situ the pictures really help to bring home how amazing adders really are.

In the first chapter, you give an overview of how our tumultuous relationship with reptiles and amphibians in the UK has changed over the last hundred years (and beyond). Do you feel that our native herpetofauna is sufficiently catered for in ecological guidelines today?

The history of the adder in Britain is sadly one of relentless persecution, from Biblical times to the point we have arrived at today where the species could be extinct across most of Britain in the next 15-20 years. There are a lot of good guides to our herpetofauna but not many address the difficult conservation issues facing our reptiles and amphibians, from climate change and persecution to the release of millions of non-native pheasants and uncontrolled dogs on nature reserves. I expect the book will prove quite controversial as it advocates a 10-point adder action plan which includes protecting in law all remaining adder sites, reporting sensational and negative news stories to the press regulator, banning dogs from sites where adders occur and making it illegal to release game birds within a mile of adder colonies.

Over the course of your career you have written several books, including natural history titles and a historical biography. How does writing in two such different fields compare?

I love writing about history and wildlife – my first two books were ‘Neville Chamberlain’s Legacy’ which included his love of wildlife (his way of coping with Hitler was to go birdwatching in St. James’s Park) and the Role of Birds In World War Two (How Ornithology Helped To Win The War) which has just been published by Pen and Sword. History books require painstaking research and you are often working with a limited amount of material. In contrast with natural history books, you can access new research, talk to experts in the field and build in your own observations, allowing you to really write from the heart. What all the books have in common though is how important wildlife is to all of us in terms of our mental health and the solace it brings even in the most challenging times.

Chapter three – The Ecology of the Adder – gives a fascinating view into the lives of these enigmatic reptiles. What advice would you offer to naturalists who would like to proactively contribute to monitoring and/or conservation efforts, or just to observe them in the field?

Adders are truly amazing. They are our only venomous snake which means they hold a very special place in our wildlife – it would be a tragedy if they went extinct across most of Britain in our lifetime. While we know a lot about the secret life of adders from research, there is still much we need to learn about how our dwindling populations are reacting to new threats like climate change and the millions of pheasants we release into the countryside every year. So amateur naturalists can really help us by monitoring sites where they occur. Anyone who is interested in doing this should join the Amphibian and Reptile Groups of the UK, the Amphibian and Reptile Conservation Trust or the British Herpetological Society and submit any sightings to Make the Adder Count.

In chapter five – Conserving Adders – you mention the importance of rewilding to the recovery of adders. We hear plenty about reintroductions of beavers and birds of prey, but the movement’s potential benefits to our more overlooked wildlife can often be forgotten. How can rewilding projects help our reptiles?

Rewilding targeted to the right places could help adders a lot. Rewilding tends to be associated with high profile species but it is also a way of helping all our wildlife. In the case of adders, Make the Adder Count showed that 90% of the sites where adders now occur in Britain have 10 or less adult snakes. This makes them very vulnerable to any catastrophic event, such as the destruction of their hibernaculum and also genetic defects due to inbreeding. As sites are often isolated from other colonies, joining together the small and scattered populations must now be a conservation priority, particularly in those areas where the species is on the verge of local extinction.

Author Interview with Thomas Halliday: Otherlands

Otherlands is the exquisite portrayal of the last 500 million years of life on Earth. Palaeobiologist Thomas Halliday takes readers on an exhilarating journey into deep time, interweaving science and creative writing to bring to life the unimaginably distant worlds of Earth’s past. Each chapter is an immersive voyage into a series of ancient landscapes, throwing up mysterious creatures and the unusual landscapes they inhabit.

Thomas Halliday has kindly taken the time to answer a few questions for us below.

Could you begin by explaining what you mean by ‘otherlands’? How did your fascination with these ‘otherlands’ begin and what drew you to write about this?

The word ‘otherlands’ came about in trying to come up with a title that reflected some level of familiarity and strangeness. It falls somewhere between the idea of something being ‘otherworldly’, but also recalls ‘motherland’ – a safe, familiar home. I think all palaeobiologists, whatever subdiscipline they are part of, have the shared goal of understanding how life used to be. Biomechanists might concentrate on the engineering of a skeleton to understand the behaviours it would have been capable of, and phylogeneticists are interested in how living things are related and changed over time, but all of it adds up into a picture of past life. I’ve always been more interested in big picture, ecological questions rather than the minutiae of anatomy – as important as anatomical knowledge is – and so writing through an ecological lens made most sense to me. In essence, it’s just putting down on paper what we as a community have discovered about life at different points, which is a useful exercise in bringing together science from groups who don’t necessarily read one anothers’ papers. I can’t visit these places except through some creative process – whether that’s a painting, an animation, or text. And I can’t paint or animate.

It is a great feat of work to bring Earth’s deep past to life and to render the unseeable things seeable through prose. How did you approach such an immense task from not only a literary perspective, but a philosophical and scientific perspective too?

Every site in the book has some kind of layout in my mind. It may be known to a fairly high degree of accuracy scientifically – the extent of the playa lake in Moradi, just over 250 million years ago in what is now Niger – is sketched out in papers on that site, so we can get an estimate of how big it was, and which way the water was flowing from. In others, our knowledge is a bit more generic but I have a mental map of where the different beats take place. The line of the story in each place moves through that space, which means that I can be consistent in timing, sights and so on. I think this internal consistency of a place is essential to making it seem immersive. Most of the actual visual descriptions of the animals and plants I use, though in my own words, are no more detailed or evocative than those of other writers, so if I have managed to create a better sense of things being ‘seeable’, as you suggest, then I think that it is everything else around it that make the scene believable. If the scene has been describing the smell of a limestone cave, that colours the subsequent description of the next animal, because mentally you begin to frame it as seen while emerging into the light. We experience an environment through all our senses, and so appealing to those other aspects of reality brings out the realness of an organism.

One of the things I most appreciated about Otherlands was how you focus on landscapes, the settings that are necessary for life to evolve, versus our society’s sensationalised image of the prehistoric world that typically conjures up images of monstrous creatures. What is it that draws us to the dinosaurs compared to the often forgotten plants, fungi, invertebrates and other species?

I blame Gideon Mantell. Well, not really, but the early pioneers of popular geology at the end of the 18th and beginning of the 19th century drew crowds because of the enormous creatures they could put on display. The first fossil animals to be displayed in sensationalist shows were mastodons – relatives of elephants – and giant ground sloths. You have to remember that this is a pre-Darwinian time, when extinction has only recently been recognised, and when the timescale of the age of the Earth is still very much debated. They drew in the crowds with claims of antediluvian monsters from some barbaric era, and I think a lot of the popular depictions of the past have remained since then. If you think of the most influential European and American artistic works featuring palaeontology over the last – Jules Verne’s Journey to the Centre of the Earth, Arthur Conan Doyle’s The Lost World, Disney’s Fantasia, all the way through the Ray Harryhausen B-movies to Michael Crichton’s Jurassic Park, there’s a common thread of violence and peril, which is undoubtedly a crowd-pleasing approach but doesn’t really reflect what biology is typically like.

That doesn’t quite explain why many fossil mammals or crocodilians, for instance, are poorly known by the public. Dinosaurs do have the advantage of being typically very large compared with the biggest land animals of today – and indeed the recent past – so if you’re going into a museum it’s a lot harder to miss the big Diplodocus than the display of fossil horsetails. There is something awe-inspiring in size, but I hope that people can take the time here to recognise the wonder in the very small things that are going around. I do of course have dinosaurs in the book, but because they have been covered so extensively, I didn’t want to deal with many of the clichés. There’s a dinosaur hunting for food, sure, but it ends in failure. The big tyrannosaur has a drink and scratches off some dandruff against a tree. There’s more to dinosaurs than violence.

I was struck by the level of detail that is revealed from the fossil record, to the point that we can know the presence of different types of insects based on the distinct ways in which they damage leaves. As you collated such an array of research for the book, were there any particular findings that captivated your imagination the most?

One piece of information that I really enjoyed learning about, just because of the implications throughout, was one that I picked up at a conference talk (and which has since been peer reviewed and published). Oviraptorosaurs are a group of dinosaurs that have been associated with nests for a long time. The name means ‘egg thief reptiles’ because it was initially assumed that they were eating the eggs, but more and more finds have accrued, including of parents sitting on the nests at the time of burial, that show that these are their own nests that they are caring for. We can reconstruct how the nests were built based on the arrangement of eggs and the nest mound – a ring of eggs was laid, and then buried, and another ring later added. But what is wholly remarkable is that we can chemically analyse the eggshells even now, and identify different isotopic ratios of calcium in each layer. The isotopic pattern is a sort of chemical signature that is tied to the individual mother that provided the raw material for the eggshell. What this means is that each nest contains the eggs of more than one mother. There are a couple of possible explanations for this, but the best modern example of communal nesting like this is in ostriches, where a single male builds and guards each nest, and several females lay eggs in the same nest. In ostriches, the males then rear the chicks once hatched – I don’t go so far as to claim this for oviraptorosaurs, as this could only be speculation, but I think the best examples of fossil record detail are those where a preserved detail of chemistry opens up a whole trove of behavioural implication.

Scientist Robert H. Cowie writes: “Humans are the only species capable of manipulating the biosphere on a large scale. We are not just another species evolving in the face of external influences. In contrast, we are the only species that has conscious choice regarding our future and that of Earth’s biodiversity.” Speaking to this, how can our current epoch defined by destructive human influence be compared to these past worlds, and what lessons might be learned?

Our epoch is known as the Holocene, and makes up the last 11,700 years of geological time. Human environmental influence extends past the beginning of the Holocene, but recently it has been both accelerating and fundamentally changing in type. With deep ocean dredging and drilling, we are disturbing ecosystems that had until now never encountered us, plastic is pervading every part of the biosphere, we are altering the atmosphere globally, and our consumption of resources has boomed. When we look to the past, we find a few occasions when some similar traits can be observed. New chemicals in an environment – from oxygen in the single-celled earth of the Proterozoic to wood in the Carboniferous – have disturbed the balance of the world, but ultimately incorporated in fundamental processes. The Great Oxygenation Event is widely suggested to have caused a turnover in microbial communities as those oxygen-intolerant species retreated to environments this new toxic gas could not reach. The delay between the origin of wood and the development of lignin-digesting bacteria has been suggested as a reason for the preponderance of peat forming swamps in the Carboniferous, although this is disputed. Whatever the reason, the laying down of peat – and then coal – changed the atmosphere radically, which led to greater aridity worldwide, ultimately destroying the suitable environment for the very trees that had caused that change. But the biggest effect we are having is that of disturbance, and for that we have to look to mass extinction events for parallels. Earth has existed in all kinds of climatic states over its history, but mass extinctions have occurred during times of sudden transition. From the end-Ordovician, when glaciers rapidly advanced and retreated from the poles, to the end-Permian, when unfathomably large volcanic eruptions deoxygenated the oceans and threw greenhouse gases into the atmosphere, to the end-Cretaceous, when the aftermath of a meteorite impact darkened the skies for years, rapid change is typically bad. Although life eventually returns, it can take millions of years, and the species that thrive afterwards are rarely those that had thrived before.

Our effects are often extreme and rapid, and part of the problem is that they are done with a short-term mindset. Some human modifications – such as the pre-Columbian cultivation of the Amazon rainforest, the development of clam gardens, or well-managed meadowlands – have increased diversity locally, and are sustainable in the long term. We mustn’t fall into the trap of thinking that humans can only be destructive, or that we are separate from the ecosystems we live in. But, looking to the past, it is clear what the consequence of destructive behaviours is. This is the Earth we live in, and we are part of this world, but worlds can change in a moment.

This book is a timely reminder of the impermanence of life on Earth, evocatively revealing the fragility of our existence. As a researcher of the past, what do you see for our future?

People often assume that I might answer this question in terms of biology of life after humanity, or of the evolutionary direction humans are heading in. Although speculation can be fun, I don’t think that’s a useful way of thinking, because as Earth history shows us, the broad strokes of biology will remain the same. There will always be the same patterns of energy flow through ecosystems, and amazing adaptations to environments so complex that to form any predictions of the truly long term is futile. But we must think ahead to our immediate future. Nobody is suggesting that humankind will become extinct any time soon – we are too generalist, too adaptable to any environment to suffer that kind of loss. But that doesn’t mean that people, societies, cultures will not suffer under the environmental change that is already underway. And of course, portraying climate change as something that is future is itself untrue; we have been feeling the effects of climate change for decades already, especially those of us in low-lying island nations, those prone to storms, or dependent on seasonal ice. The effects will continue to accrue and to spread, but I remain optimistic that we will do what needs to be done – cease extraction of fossil fuels, move to a less all-consuming society, and support less wealthy countries in improving quality of life through renewable energy rather than repeat the errors we have repeatedly made. I am optimistic, and hopeful, but it is not something that will just happen. I see hard work, and that it will be entirely worth it.

Author Interview with Danielle J. Whittaker: The Secret Perfume of Birds

In The Secret Perfume of Birds, evolutionary biologist Danielle Whittaker reveals how she came to dispel the widespread myth that birds cannot smell. Mixing science, history and memoir writing, Whittaker offers a humorous and compelling narrative to describe how birds smell and how scent is important for all animals. The book offers readers a rare opportunity to witness the unfolding journey of scientific research and the surprising discoveries it can make.

Danielle kindly agreed to answer some of our questions below.

How did you find yourself studying the science of avian scent?

I was originally studying how birds might choose their mates on the basis of certain immune genes, following the idea that animals could prefer mates with different genes than their own, leading to offspring with stronger immune systems. I was struggling to sequence these genes, and I complained to a colleague who happened to be studying bird brains. He said, “I don’t know why you’d study that in birds – information about those genes is sensed by smell, and birds don’t have much of a sense of smell.” I had never heard that before, and the idea that a whole group of animals would lack such an important sense seemed absurd to me. So, I started investigating.

The idea that birds lack a sense of smell has persisted for more than a century despite being disproved by yourself and others. How did you navigate tackling long-held assumptions in the scientific community?

I conducted rather slow, incremental research, following where the questions led me. I started out with simple, clearly defined experiments to test the birds’ reaction to odours from other birds. Then moved on to working with chemists to analyze the information content present in the odours given off by birds. Little by little, the scientists who heard about work in this area started to pay attention, and soon more people started researching bird smells!

I found the most fascinating part of your research to be the discovery that bird scents are linked to their microbiomes. How did you come to look into bacteria and could you expand on their important role?

When I first talked about my research with my now-collaborator Kevin Theis, he looked at the list of compounds I had found in bird odours and said, “those types of compounds are by-products of microbial metabolism. Have you looked at whether symbiotic bacteria are producing these odours?” I had never thought about that possibility before! Kevin studied the bacteria in hyena scent glands and how they produce the odours used by hyenas when they scent mark. Kevin and I teamed up to study the question in birds and we found out that he was right.

In this book, you demonstrated the importance of scent in bird reproduction. I wonder if human-related impacts on our environment are influencing changes to the unique scents of different species, with consequences for their reproductive success – is there any current research being done on this?

I am hoping to look at whether adapting to living in urban environments has affected the microbiome, and thus the scent, of bird populations compared to their non-urban counterparts. It’s very interesting to think about the long term consequences of such changes, but I don’t think there is much research about that yet in any animal.

Your work focuses on the dark-eyed junco, a bird commonly seen in North America. Is there a particular reason why you chose to study this species and do you have any plans to study other birds in this way?

I was a postdoc in Dr. Ellen Ketterson’s lab at Indiana University, and she has maintained a long-term study of dark-eyed juncos for many years. I quickly found that juncos were very easy to work with, and I appreciate that, in many ways, their biology and behavior makes them ‘typical’ northern hemisphere songbirds – which means they are a good model for understanding lots of bird species. I have studied odours in other species as well, in particular the lance-tailed manakin in Panamá. I am always interested in new birds!

Where will your research take you next? Do you have any plans for further books?

Right now, I’m interested in how social behavior changes animal microbiomes through bacteria sharing, and how that might affect odours. I’m also interested in looking at how microbiomes and odours have changed in urban populations of juncos. Beyond my junco research, my professional life has taken yet another unexpected turn, and I am transitioning to a new job as managing director of the Centre for Oldest Ice Exploration (COLDEX) at Oregon State University, where they study Antarctic ice cores to learn about ancient climate change. Maybe I’ll get to visit Antarctica and write about my new adventures!

SCOTLAND: The Big Picture: Q&A with Peter Cairns

In response to the growing climate and biodiversity crisis, SCOTLAND: The Big Picture is working to drive the recovery of nature across Scotland through rewilding. Using positive storytelling, they hope to inform and inspire change, while also enabling practical rewildling through partnerships and collaborations. They see a role for everyone in creating a wilder Scotland, with a vision of a vast network of rewilded land and water where wildlife and people flourish.

Executive Director, Peter Cairns, has kindly taken the time to answer a few questions for us.

Could you tell us about the work that SCOTLAND: The Big Picture does and how the charity began?

Our core team has been involved in environmental communications for more than two decades so when the rewilding story really started to gain momentum in Scotland, probably about a decade ago, we were well placed to document it. The ‘R’ word (rewilding) remains contentious to this day, but as we embraced it at an early stage, we gradually – and unwittingly – became the voice of the movement, or at least one of them. That gave us a platform and in 2019, we became a fully-fledged charity, working to drive the recovery of nature across Scotland through rewilding, in response to the growing climate and biodiversity crises.

One part of your vision is creating a future for Scotland where people thrive, but development and industry can sometimes be in contention with wildlife. How do you think a nature-based economy could allow for long-term restoration of habitats without negatively impacting communities?

Pitching people against nature helps neither. We need to look for new ways to marry our economic systems with our ecological systems.

We believe the transformational recovery of nature can only be achieved with the support of local communities – rewilding will only work if people can see social, cultural and economic benefits that work in tandem with ecological recovery.

The original principles of rewilding were founded on the ‘3C’s’ – cores, corridors and carnivores, and there’s no reason why such a model can’t be explored in Scotland. ‘Cores’ means areas that are effectively given over to nature, allowing natural processes to shape and govern the land. Around these could be buffer zones, where a high degree of ecological functionality is maintained, but a range of nature-based economic activities, such as payments for natural capital, wild produce and diverse nature-based experiences, help support vibrant communities.

SCOTLAND: The Big Picture was a founding member of the Scottish Rewilding Alliance, how have you found the reception of this alliance amongst organisations? Are they generally in favour of large-scale rewilding in Scotland?

Rewilding has come to mean different things to different people and that can be a challenge, but it also provides opportunity for it to be rolled out at different scales and settings, while still making a valuable contribution to nature recovery. The members of the Scottish Rewilding Alliance are all at different stages on their journey, but all recognise that the traditional models of conservation have failed to arrest and reverse ecological decline, and are committed to a fresh, more ambitious, more holistic approach.

Outside of the Alliance, there is a growing appetite for change across Scotland, as land managers look at the social, political and economic horizon, and realise that business as usual is not an option.

Your upcoming feature-length documentary, Riverwoods, reveals the perilous state of Scotland’s salmon and presents the inextricable relationship between fish and forests. What are the main threats to this species and Scotland’s rivers, and why is salmon such a valuable species for forest ecosystems?

Atlantic salmon is a modern-day canary in the mine – an indicator of ecosystem health. The reasons for its spectacular decline, like so many species, are many and complex, and this film doesn’t attempt to address them all. Instead, Riverwoods tells the story of salmon – young salmon in particular -in our rivers, and carries a simple message: The health of our rivers and all the life within them, is directly dependent on the health of the landscapes through which they flow.

Perhaps to set the scene, I can quote from a recent article we produced on this very subject:

6,000 years ago, a rich, dynamic woodland ecosystem stretched across 60% of Scotland’s land area. These were diverse forests of Scots pine, oak, rowan, birch, aspen and willow; a complex community of shrubs and bushes, tall trees, tiny trees, dead and dying trees, all intertwined in a constantly evolving system.

Flanking Scotland’s rivers and lochs, these woodlands were shaped by beavers, creating fresh coppice growth, new wetlands and backwaters, raising the water table and toppling insect-laden trees into and alongside the river. The decaying timber provided food and sanctuary for more invertebrates, as well as casting dappled shade across the river’s surface.

Spent salmon, exhausted after an epic journey from freshwater to sea and back again, fed brown bears, wolves, eagles, ospreys and otters, before the precious marine nutrients found in their carcasses, were taken up by the soil nourishing fresh plant and tree growth.

In other parts of the world, the connectivity between river, forest and ocean, and the bountiful runs of salmon that still persist, creates a living, breathing, working system. Here in Scotland, just 3% of our native forest remains, clinging on in isolated, lonely fragments and despite their reputation for beauty and drama, the glens through which our rivers run, are often bare and treeless, reflecting the centuries of ecological decline that we have come to accept as normal.

How do you think Scotland’s river catchments can be restored? What changes need to take place?

Fundamentally, we need to perceive and manage river catchments as a complete ecological system and not as a series of individual species and habitats. No species exists in isolation and again, the health of our rivers is dependent on the health of the surrounding landscape.

More immediately, many of Scotland’s rivers are getting warmer, some approaching the lethal limit for young salmon, so these fish are crying out for the trees that once shaded and nourished them. The roots of trees like alder and willow, which can live in the water, protect fish from the sun and provide hidey-holes during high flow events. Tree roots help stabilise riverbanks and woody structures like fallen trees in the river, create deep pools and riffles providing salmon with the structurally diverse riverbeds they favour. A lack of overhanging trees also reduces insect numbers which in turn, means less food falling from branches into the mouths of hungry fish.

For people inspired by your work, how would you suggest they get involved?

We normally recommend 3 actions:

WILD YOUR SPACE: It’s easy to imagine rewilding at a landscape scale but this is a journey that offers space for everyone. Parks, gardens and public spaces can all make a valuable contribution to a landscape rich in nature and passionate individuals and communities are already working together to create more space for bats, bees and butterflies. Everyone can get involved.

MAKE SOME NOISE: Rewilding is as much a change in mindset as it is a physical change to the land or sea, so it’s good to talk. Most people don’t realise that Scotland has become a nature-depleted nation. Talk to family, friends and work colleagues about the potential of a rewilded Scotland for nature, climate and people. Encourage them to join our Big Picture community.

PUT YOUR MONEY TO WORK: There are many ways to invest in rewilding. You can support businesses such as local farms that are working to restore wildlife, or nature tourism operators who donate part of their revenues to rewilding. And of course, you can help make more rewilding happen by supporting organisations like SCOTLAND: The Big Picture.

Lancashire Peatland Initiative: Q&A with Sarah Johnson

The Lancashire Peatland Initiative, run by the Lancashire Wildlife Trust, has delivered habitat restoration across over 200 hectares of degraded lowland raised bog. These habitats are peatland ecosystems that develop primarily in areas less than 150m above sea level, particularly in cool, humid regions. These deep bodies of peat can be raised several metres higher than the surrounding land and are much wetter, usually covered in typical bog vegetation, such as cotton grass, sphagnum moss and heather.

This pioneering initiative has spanned the past three decades, with active restoration activities on numerous sites, including Little Woolden Moss, Winmarleigh Moss SSSI and Astley Moss SSSI SAC. The Trust’s tireless efforts, in collaboration with Natural England and other partners, has ultimately halted the decline of these nationally significant sites and species, resulting in an expansion of active raised bog habitats.

The Lancashire Peatland Initiative won the NHBS sponsored Best Practice Award for Large Scale Nature Conservation at the 2021 CIEEM Awards. Project Manager Sarah Johnson has kindly taken the time to answer a few questions for us.

Could you tell us about the Lancashire Peatland Initiative and how it started?

The Lancashire Peatland Initiative was born out of a desire to bring together and co-ordinate all of the peatland restoration work happening in Lancashire, Manchester and North Merseyside, raising awareness of the importance of these amazing habitats, and ensuring their protection in the future.

In 2019 we were delighted to be awarded funding from the Esmeé Fairbairn Foundation to create and support the Lancashire Peatland Initiative. This allowed us to fund Project Officers, Assistant Project Officers, communications support, and myself as Lancashire Peatland Initiative Project Manager, to work across all of the Wildlife Trust for Lancashire, Manchester and North Merseyside’s peatland nature reserves in the area. We also co-ordinate the Lancashire Peat Partnership and the Northern Lowland Peatland Coalition, and work closely with the Great North Bog Coalition and the Great Manchester Wetlands Partnership, bringing together partners and other organisations who are involved in our peatlands.

This allows the Lancashire Peatland Initiative to work on our own peatland restoration projects, but also support those of our partners and develop new projects across areas of commonality and innovation.

How did these habitats become so degraded and what are the main threats they are currently facing?

Our peatlands face threats from all directions. Historically peatlands have been seen as wastelands that needed to be tamed by humans before they could be exploited, either for conversion to agricultural land or for the extraction of the peat. Deep ditches were dug to drain the water from the peat, destroying these fragile ecosystems.

Unfortunately, many of these same threats are still faced by our peatlands today. Drainage and conversion to agriculture, overgrazing, rotational burning and extraction of peat for use in the horticultural industry has left only 13% of England’s peatlands in a near-natural state.

Public opinion is often integral in the success of large restoration projects such as this; how have you found local reception of peatland restoration? Are people generally supportive?

Peatlands are not always at the top of people’s agendas, so we are working hard to get the message out there about the importance of our peatlands, not only to provide a habitat for lots of amazing plants and animals but also in our fight against climate change, as natural flood mitigators, water filters and protection against wildfires.

However, we have found that once people know about these fantastic ecosystems they really support our work to restore and care for them. Of course, there are some issues still to fully answer, such as the need to protect both peat and our food supplies, so much of which is grown or grazed on drained peatland. But we have found that as the plight of our peatlands enters more people’s consciousnesses, they are more willing to work with us to find solutions.

The sale of peat compost to gardeners is to be banned from 2024; how do you think this will affect peatland degradation and restoration? Are there any other policies you think are needed to protect these habitats?

A ban on domestic sales of peat compost is a fantastic step towards protecting our peatlands. But so much more still needs to be done. Large amounts of peat are still being used in commercial horticulture, growing the plants that are for sale in your local garden centre, and this is an issue that is yet to be addressed. Another really damaging practice is the growing of lawn turf on drained peatlands, one of the highest carbon dioxide emitting uses of peat that not many people are aware of.

However, we do need to be careful that we are not simply exporting the issue elsewhere to areas of lower regulation. For example, Ireland recently announced an end to its peat extraction, but just a few months later there were reports of millions of tonnes of peat being imported into the country from one of the Baltic states.

We also really need policy support for the movement towards more environmentally sensitive management of land on peat-based soils. For example, the adoption of paludiculture or higher water table agriculture (wet farming) and land management could have a huge impact on CO2e emissions from our peatlands, but until these practices can be shown to be financially viable how can we expect landowners to take up these changes? This is an area where public subsidies and financial incentives could make a real difference.

There also needs to be an immediate end to all peatland burning, as the current legislation is riddled with loopholes.

Species reintroductions began in 2018; how are the species chosen for reintroduction? What are the criteria for determining whether an area has recovered enough to support these reintroduced species?

Species reintroductions are one of my favourite parts of my job! Currently, we are focusing on reintroducing species lost from Greater Manchester, and so a working group from the Great Manchester Wetlands Partnership comes together to appraise which species would be suitable for reintroduction. However, this can only happen after years of habitat restoration to create the right conditions for these returned species to thrive.

A recent success story was the reintroduction of the large heath butterfly. Locally known as the Manchester argus, the destruction of its peatland habitat drove it into local extinction almost 150 years ago. However, by following strict IUCN guidelines and working closely with Natural England and Chester Zoo, we were able to reintroduce the species to Astley Moss in the summer of 2020. Since then we have had the privilege of seeing the first native population flying on the moss this summer.

With the current COP26 summit, what are your hopes for the future of the Lancashire Peatland Initiative and the restoration of these habitats?

We have really high hopes for the future of our peatlands. It seems clear to anyone in the know that we need to be prioritising the recovery of these habitats as they can provide us with quick, massive wins in terms of carbon reductions. For example, at our pioneering carbon farm we have already seen a 90% reduction in CO2e emissions from the site, compared to an adjacent area of drained peatland that has been converted to agricultural pasture. This has been achieved in just over a year by simply re-wetting the land, and give us another year or two to fully re-vegetate the site and we expect it to become a functioning carbon sink.

What we are really hoping to see out of COP26 is a commitment to ambitious peatland restoration targets, that are backed up by both the policy and the funding to actually achieve this. In the words of Greta, we need action now – not more ‘blah, blah, blah’!
