In The Accidental Garden, author Richard Mabey takes the reader on a journey through his own garden in Norfolk and explores the possibility of nature becoming humankind’s equal partner. He watches as his ‘accidental’ garden becomes its own director and reorganises itself in its own way, with ants sowing cowslips in their own patterns, roses serendipitously sprouting amid gravel, moorhens nesting in trees and other fascinating interactions.
Richard Mabey has authored 30 books since becoming a full-time writer in 1974, a number of which have won awards, including the East Anglia Book Award, National Book Award and Whitbread Biography Award. He sat on the UK’s Nature Conservancy Council in the 1980s, has been awarded two Leverhulme Fellowships and three honorary doctorates, and became a Fellow in the Royal Society of Literature in 2011.
We recently had the opportunity to talk to Richard about his most recent book, where we discussed his approach to garden ‘by’ wildlife and the challenges he faced, the extent to which nature can thrive itself when human involvement is minimised, projects that are currently occupying his time and more.
Can you tell us what inspired you to write The Accidental Garden?
I’ve been meditating on many of the book’s themes for a long while – the paradox of our seeming new respect for nature co-existing with an obstinate reluctance to relinquish control; our obsession with tree-planting, as if trees have lost the ability to reproduce themselves; the lust for tidiness over vitality. What sparked the book – and set it in the theatre of our own garden – was a Dark Bush-cricket singing at midnight from the hollyhocks on that hottest-ever day in July 2022. It sounded like an anthem of hope.

You mentioned in the first chapter that you try to garden ‘by’ wildlife as much as for it. Have you faced any challenges while using this approach, and what tips would you give to someone who wants to try and garden by the wildlife and biodiversity found in their own patch?
The Accidental Garden isn’t an advice manual. It’s a hesitant, personal account of what happened when we opened the gate to what I call ’parallel development’ in our space. We do what humans do in gardens, and allow other organisms to do what they want. Allow them to become subjects rather than objects, and effectively become fellow gardeners. So I left the bramble patch be, instead of digging it up to plant some runtish nursery-forced oakling. Result: Field Maple and Hazel saplings growing through its protective thorniness. I kick bare patches in the grass and see what self-seeds. Broomrapes, Heartsease and Bee Orchids have been among the surprise settlers. If you’re prepared to junk judgemental labels like weeds and pests there are very few challenges from this approach.
There seems to be evidence that, if left to fend for itself, nature can thrive and colonise without human involvement, as seen along the Dorset coast in the 1800s. What do you think humankind can learn from this going forward?
I’m continually amazed that we find nature’s ability to thrive and adapt surprising. How else could the planet have supported an abundance of life for billions of years before humans arrived on the scene? The natural world has never lost that enterprise and agility. Our reluctance to take advantage of this, to capitalise on adaptive solutions to environmental change, is a typically arrogant stance by our species, still stuck in its ‘dominion over’ mode, and our loss, as well as the natural world’s.
As you mentioned in one of your chapters, many people relish how non-native plant species can transport you to other places, while they also play a key role in garden biodiversity and over time can become at home in the UK, as seen with Snowdrops and Horse Chestnut. How do you think we can nurture the inevitable introduction of new species without this disadvantaging native plants?
The only visiting species we have any trouble with is Ground Elder, and otherwise our patch is developing into a resilient fusion garden. Native plants and animals form new communities with benign settlers. I’m writing this in May just feet from a large and dazzling patch of self-sown flowers that have established themselves in the gravel round the house, including Red Campion, Green Alkanet, Lamb’s Lettuce, Red Valerian, Hedgerow Cranesbill, Ox-eye Daisies. My interest is in the vitality and autonomy of this community (and its insect life – Hummingbird Hawk-moths are the stars!). But in terms of pure visual attractiveness it would match any herbaceous border. I’m also pleased by the way Turkey Oaks are regenerating in and beyond our patch of treeland, growing alongside the Wild Cherries and Ashes, and proving more resistant to deer browsing than English Oaks. Of course, many newcomers cause trouble away from their home ground. But in an environment that is being damaged so much by climate change, we need new species to keep a biologically rich tapestry of life here, in case our traditional species have trouble coping. ‘Nativeness’ has always had strict time limits, at both ends.

What was the most interesting finding that you came across while undertaking this journey with your own garden?
I think learning about eliasomes, the little parcels of fat on the ends of many seeds that are ants’ rewards for acting as beasts of burden. (They ferry the seeds to their hills and feed the fat globules to their grubs.) Our red ants’ hills are now like living standing stones and I like to think they are responsible for Cowslips now carpeting most of our grassland.
What do you hope the reader can learn from The Accidental Garden?
I’ve been astonished by the inventiveness of our fellow beings when allowed a little leeway to do their own thing. When we drop our paternalistic attitude, our belief that we know best what should live where. Gardens are often compared to theatres, with the gardener as writer, director, set designer rolled into one. Can’t they also be open stages where uninvited, unsupervised species and ancient processes of colonisation and decay can improvise their own landscapes? In the 20 years we’ve been here one half of our plot has transformed itself into a kind of common, with patches of treeland and open grass, and a total of over 150 wild plant species arrived largely of their own accord. A garden is only in the smallest sense a microcosm and metaphor for the planet. But in it it’s possible to glimpse larger lessons about neighbourliness and cooperation, and the fact that the natural world is not intrinsically a victim, in need of constant intensive care.
What are you occupying your time with at the moment? Do you have any other books in progress that we can hear about?
At my age I should be put out to grass. But I can’t stop thinking and scribbling. I’ve just finished an expanded new edition of my 1993 book on the cultural history of Nightingales, Whistling in the Dark, out next year. And I’m dogged by a fancy of tracing the wild thread in the art of nature (always my second subject) from the cave paintings in Derbyshire to Andy Goldsworthy’s spring-flower-enclosing snowballs. But maybe I should just be content to use my walking stick (my Instrument of Minimum Intervention) to scratch more patches in the grass.

Join author Kat Hill on a journey across England, Scotland and Wales to explore 15 remote bothies, and uncover the beauty, history and stories of these wild shelters. In this stirring book of adventure, peace, wilderness and refuge, she intertwines her own story of heartbreak and new purpose, while taking into consideration the environment, what we owe to it, and why we all crave escapes into the remote.
Kat Hill by Nicholas J. R
Kat Hill is a Senior Lecturer in History at Birkbeck College, London, and her current research project is focusing on questions of landscape, people, and heritage in the bothies of the Scottish Highlands, as well as non-conformist religious communities in Europe, America and the Global South. She holds a PhD from the University of Oxford in 2011, where she also received a British Academy Postdoctoral Award, and she authored the prize-winning book, Baptism, Brotherhood, and Belief: Anabaptism and Lutheranism, 1525-1585.
We recently chatted with Kat about what inspired her to write this book, how technology is changing the bothying experience, what she thinks the future holds for bothies and more.
Firstly, could you tell us a little bit about yourself and how you came to write a book about bothies?
I’m a writer and researcher living on the northern tip of the Isle of Skye. If I am not reading or thinking up project ideas, I am either out in the hills or beavering away at my other role, working with local communities for Highlands Rewilding. In my past life I was an academic historian (as well as an international Brazilian Jiu Jitsu competitor), but last year I took voluntary redundancy from academia to pursue my writing and creative practice more fully, as well as aiming to do something good for the world in an age of climate crisis and environmental breakdown. That need, to work on something to do with the living world, was part of the inspiration for writing Bothy. I’d grown weary of academic life, and London in particular, my personal life was a mess, and I felt disconnected and unsettled. And then I got invited to a bothy, Cadderlie to be precise, on the edge of Loch Etive.
When I first went to Cadderlie, I never intended to write a book about bothies. But I loved the whole experience, and the more I found out about them, the more drawn I was to these shelters. They embodied so many things I was interested in – landscape, our connection to place, environmental histories, material histories of people and the living world, and just generally being active and outside. Finally, the plans I had for quite some time to change direction and escape the life I was living came to fruition. Especially with that weird caesura that Covid provided, I had space to make notes and think, and in that time, I found the ability to write in a way I had not thought possible. I did an MA in Environmental Humanities alongside my job, kept chipping away at the work and was lucky enough to find an amazing agent. This book is not a memoir per se, though there’s quite a bit of my life in it, but I would say it’s a personal response both to the challenges of my own life and to the crises we see around us.
Were there any authors or books in particular that inspired you when you set out to write Bothy?
There’s a real mix of things that shaped my writing, as I am sure is the case for any writer, but one of the things I most enjoyed in the process was taking inspiration from an eclectic mix of authors and books. Too many to name, but I’ll give a flavour. Nature and travel writing has always felt like such an obvious go to. I remember my mum introducing me to Patrick Leigh Fermor’s A Time of Gifts when I was younger and his combination of learned observation and vivid writing about the world captivated me. Other travel writing like Steinbeck’s Travels with Charley always spoke to me. As for more recent nature/travel writers, I love Cal Flyn’s work, Rebecca Solnit, Judith Schalansky’s books, and Nick Hayes’ Trespass, and I have immersed myself in environmental writing from so many people. To name a few – Robin Wall Kimmerer, Anna Tsing, Kathleen Jamie, Robert Macfarlane, and Andri Snær Magnason.
But there were also personal elements to the book, and so when I was thinking how you deftly discuss your life and its meaning, it was to writers such as Deborah Levy, Amy Liptrot and Helen Macdonald that I turned. Fiction and literature shaped the work, too, novels like The Overstorey or Ursula Le Guin’s novels, short stories and essays. And I’ve always loved poetry, though I am not sure I am bold enough to write it for others – although, who knows? – and countless collections sit on my shelf, from Edna St. Vincent Millay to Alice Oswald, Rainer Maria Rilke to Liz Berry.
At the heart, too, I have always drawn inspiration from my academic background and academic writers, mainly historians and archaeologists, for example Natalie Zemon Davis, Tim Ingold and Jane Bennett, but also philosophers. If you don’t know Timothy Morton’s book Dark Ecology, then I highly recommend it. I also always looked to those whose work is accessible beyond the world of scholarly writing. I was given a great lesson in that by my academic mentor Lyndal Roper, a historian of sixteenth-century Germany, and at the back of my mind was always the sensitive, layered, textured approach she had to writing about past lives.
People find solace and healing in all sorts of activities and all manner of things. Why do you think bothies were the thing that helped you at a time when you needed it?
It was a particular mix of things that made bothies so meaningful for me. I’d not been to Scotland much before Cadderlie, so part of it was being able to spend time outdoors and simply be active in beautiful landscapes. I grew up in Shropshire, so especially when I went to the Welsh bothies it felt like I was rekindling a connection to the younger version of myself. But they also stirred the historian’s interest in me because in the bothies there are visitor books which are left for anyone to sign, and these are a startling, intriguing record of ordinary lives. Given the chance to write a poem, draw a doodle or write out a life history, most people do. I’ve worked so often with archival documents that give hints of past lives and material histories of human stories that these felt like such a rich source.
I felt an immediate connection to the people on these pages. And I loved that, because bothies arrived in my life at a turning point, when I needed that connection. It was a funny, difficult time personally for me when I found bothies. I was struggling with what direction to take, and I am not going to lie, the previous decade had been dark, difficult, and filled with depression and anxiety. On the outside everything looked great. I was doing really well in my academic career, I was living in London in Hammersmith, I was competing in, and winning, BJJ tournaments all over the world. But underneath was a bone-deep exhaustion. The long aftermath of a divorce and then the trauma of a difficult, fractious, toxic relationship had taken its toll. I found bothies as I came out of that. I entered a new relationship and prised myself away from the life that was making me unhappy, I loved some of the anonymity yet intimacy that bothies gave – you never know who’s going to be there which produces a strange kind of bond with fellow travellers- and the respite they provided from normal rhythms of life was welcome. You have to lead a pretty simple life with only camping gear and what you carry with you, even if that retreat into plain living is a manufactured choice.
This process for me wasn’t sudden and revelatory. One thing I talk about in the book is that you don’t just go out into nature and find a cure. But there’s little doubt that the company of the living world (and finding time for connection, consideration, and above all perhaps, play) is soothing and healing. Everyone’s bothy experience will be different but for me, in these places, I was able to reshape myself after a difficult decade as someone who was once again creative, outdoorsy, adventurous, a nature lover, kind to others- someone who was happy.

Do you think that technology and social media have changed the bothying experience?
For example, now you can discover the details and locations of individual bothies online and then use a GPS to find your way there with ease. I never knew bothies before they were on Google maps, blogs and Instagram, so that’s always been my experience of the bothy world. But it’s certainly easier to find them now than it was in the 1970s or 1980s. It’s a different world, but I guess the key question for lots of bothy users is whether that alters or fundamentally destroys the bothy experience. Some would say yes, and I understand the frustration. Influencer posts about the same tourist spots in the world are wearying. And there is a very important debate to be had about responsible access to landscapes and environments, or the damage we can do as tourists. Working as I do in the rewilding sphere part of the time, I am often at the sharp end of these conversations about the tensions between human and non-human interests in a place, local and non-local needs.
However, I also don’t think that all of the online stuff is bad in the bothy world. To survive, they need to be used and a new generation is part of that. Bothies are rooted in the desire for access to the countryside and in the working class ‘revolution’ for leisure and recreation in the hills that followed World War One. Expensive hotels and fancy tours were out of reach for working young men and women who suddenly had a bit more time for leisure, but bothies were free. So I find the private club notion of bothies, of pulling up the ladder after you, more than a little problematic as it seems to go against the idea of access and the right to roam.
Some bothies have shut due to claims of overcrowding and parties – though I have never really seen raucous behaviour myself – but it’s all too easy to blame people without a voice as the culprits. Without labelling all landowners as evil either, this is really a debate about rights to the outdoors, access and how we develop responsible, caring relationships to landscapes. I think bothies can be part of that.
Some bothies remain secret and I, for one, am not going to plaster them over the internet. But I have seen so many young people with a copy of Geoff Allan’s Bothy Bible in hand, loving the outdoors, and that makes me happy. I am sure information sharing has changed the experience of bothying but nothing is ever static in the world. Indeed, perhaps it’s a particularly human thing to be nostalgic for the moment just past, to get misty eyed about days gone by, rather than live in the present moment and to enjoy that for what it is. It makes me think of a line from an Office US episode from Andy Bernard: ‘‘I wish there was a way to know you’re in the good old days before you’ve actually left them.’
How important do you think isolation is to the spirit and experience of the bothy?
There’s a really touching story, I talk about in the book which comes from a bothy visitor book entry. A man has returned to a bothy which he used to come to with his wife, their last trip of such a kind before she died of cancer. For him, as for so many others, the bothy may be relatively remote and cut off from some of the comforts of modern life but it’s not isolation per se that makes it special. It’s fellowship, companionship, love. Of course, there is a kind of isolation. But isolation from what is the key, as it’s not from people and places in a secluded wilderness, often quite the opposite as you will normally meet a new acquaintance. Some people do love being in a bothy alone and I have had delightful, quiet evenings by myself or with just a friend, but also plenty of entertaining nights with strangers.
But even when you are alone, you aren’t really isolated because you are connected to the place around you, from the bothy mouse to the howling wind, to bellowing stags to querulous birds. Besides, bothies only exist because these were, and are, lived, worked landscapes. To imagine you are in an isolated wilderness is to do them a disservice.
What do you think the future holds for bothies? Will they forever be old stone buildings, or will they evolve to include less traditional and/or newly built structures?
I’d say bothies already are evolving in new ways and there are some new MBA bothies opening up, more cottages reclaimed and restored. I’d like to think there will always be stone bothies withy smoky walls and wooden floors because they have given me so much. But the bothy idea has been taken in many different directions: such as artistic residencies run by Bothy Project, or the wonderful Taigh Whin bothy and house run by partners Sarah MacLaren and Sophie Howarth, which offers low-cost holiday accommodation for people working for the common good – carers, community workers, teachers. This place (the house of gorse, it means) is a beautiful reimagining of the idea of shelter and connection in a bothy.
And then there’s the luxury tourism bothy which is pretty far away from a traditional bothy, but I guess in some ways draws on the ideas of simplicity and shelter. The idea of a hut, a shelter, a shieling is malleable and changing but also speaks to a basic need for refuge or rest. So, the idea continues to have power, increasingly so perhaps in a fractured and complex world. And there’s a future to the bothy there, not just a past. The delicate balance of past and present is at the heart of bothy life, the retreat from modernity whilst knowing that this retreat is in some way dependent on the contrast the simple life provides with the contemporary. If there was no city or phone signal to escape from then I think bothies would be a whole different prospect.
That’s why I think there’s a future for humble bothies of the stone wall variety, alongside the fancier versions, as they have lessons to give us about what matters. They ask us to question what we need, what makes us happy, and what we can do without.
Finally, what is occupying your time at the moment (professionally and/or personally)? And can we expect more books from you in the future?
Life has been really busy, professionally and personally. I’ve just moved to Skye so I am enjoying settling into the new house: filling up bird feeders, painting walls and walking to the beach. In between writing and reading, I have a part time role as a community engagement co-ordinator for Highlands Rewilding so I have been learning more and more about the practical implications of changing land use, climate change and the delicate balance between people and places.
I don’t think I can ever imagine not writing though, so there’s plenty of scribbling too, some articles and grant pitches but also new book ideas. There will definitely be another book! Having moved about 15 times in ten years, it’s wonderful to have a home again and that’s starting to shape my writing too. When I was working in academia, I did a tonne of research on Amish and Mennonite migrations, so maybe there will be something about home and finding our place in this world.
I am also embarking on a multiyear interdisciplinary project with photographer Nicholas J R White on places of shelter and refuge across the world, places where people stay for a short while. We’ve just got back from the Shiant Isles in the Minch, a beautiful place. Soft in summer, I imagine, but we were there at the time of the season’s changing when there’s still harshness in the air, winds cold, seas wild and sun shining. It’s already provided lots of food for thought. I am also out in the US later this year for a fellowship at the IAS at Princeton, so I might find my way up to some fire lookouts à la Gary Snyder and Jack Kerouac.
So, lots to keep me busy. Life is starting to settle again. I am in a happy place, surrounded by loving people. And I might even start some BJJ classes again.

An exploration of botany for beginners, How to be a Bad Botanist is a must-read that opens our eyes to the world around us. Through this charming and inspiring work, Barnes takes us on a fascinating journey on the complex nature of plants, and enthrals us with tales to help us appreciate the diversity and wonder of the natural world.
Simon is an author and journalist who has worked on a number of nature volumes, including the bestselling Bad Birdwatcher trilogy and Rewild Yourself. He is a council member of the World Land Trust, a patron of Save the Rhino and honorary vice-president of the Bumblebee Conservation Trust.
We recently had the opportunity to talk with Simon about how plants caught his attention, the importance of botany and how we can all learn to be Bad Botanists.
How to be a Bad Birdwatcher, published in 2004, rapidly became a birdwatching classic and this year was republished as a 20th anniversary edition. What prompted you to turn your attention to plants for your latest book?
It all began with a damascene experience on Orford Ness. This is a place where military and natural history collide. On the same visit I was able to see a Great White Egret and the casing for an atom bomb. It was, I read, about the same size as the one they dropped on Hiroshima.
My brain was somewhat scrambled by this. After a while I sat on the beach, my mind full of life and death and memories of a visit to Hiroshima, pretending that I was having a bit of a sea watch. It was then that I noticed a colony of plants. Growing in the shingle. Which is impossible. But there they were. Growing. Living. And the extraordinary way that life seeks to live, even in the most difficult circumstances, really rather got to me. These strange plants seemed to make sense of this strange, awful and wonderful place.
I worked out that the plants in question were Sea Pea, Sea Kale and Yellow Horned Poppy: and my own life was better for doing so. Soon, I would be looking at old plants with new eyes.
How to Be a Bad Botanist is a fantastic exploration into the world of plants and botany itself. Where is a good place to start for aspiring botanists?
What’s required is a subtle but drastic mental shift. After my Orford Ness moment, it was clear that plants were now something to do with me. Something personal. I was doing what I wanted aspiring birders to do when I wrote How to be a Bad Birdwatcher. Only with plants.
And the first thing I wanted to do was to be introduced. To know the name. Always the first step towards greater intimacy. So, when I saw a tree, I found myself asking, what sort of tree? I made the delightful discovery that I knew more than I thought – oak, conker, holly. It wasn’t the hardest thing in the world to learn a few more – and all at once the adventure was gathering pace.
Yellow Horned Poppy by Cindy Lee Wright.
One of the first things that struck me about the book was how funny it is (I particularly enjoyed “my sitting was devoid of porpoise” when lamenting the lack of marine mammals spotted during a period observing the sea). Do you think humour and levity are important in providing a gateway into a topic that might originally seem highly specialist?
I’m glad you liked the porpoise joke. It’s one of those lines you know you really ought to cut, but haven’t the heart.
And yes, humour is essential. It’s essential to almost everything. Humour doesn’t compromise seriousness. Humours enriches life. There is humour in the greatest art – Ulysses, A la recherche du tempts perdu, Hamlet, The Waste Land, Metamorphoses. Humour humanises, bringing meaning and proportion to all we do. At a funeral, what touches us most deeply are funny stories from the life of a person we have lost.
Humour doesn’t make things trivial. When appropriate, humour makes things profound… in a funny sort of way.
Why do you think that botany is important and what can it bring to our lives?
Everything starts with plants. Plants are the only things that can eat the sun: the power of the sun allows them to make their own food, and that feeds everything else that lives (unless you live in a hydrothermal vent at the bottom of the sea, of course). Lions couldn’t live without plants: they just eat them at one remove.
Those of us who like nature tend to have areas of specialisation, and that’s only natural. But nature itself isn’t about separation: it’s about the way everything fits in together. You can’t really get a handle on your own specialist subject, no matter what it is, without understanding the way it’s driven by plants.

The final chapter relates to a decline of the natural world – what more could we do to support our native wildflower populations in the UK?
The first thing to do is to look after any piece of land you have control over and make it richer and wilder. Sometimes neglect – what conservationists call “minimum intervention” – is the best policy, and it’s assiduously practiced at our place in the Broads.
The second is to support good organisations: your local county wildlife trust (and yes, there’s one for London) and the excellent Plantlife.
And after that, just show people wonderful stuff: here come the waterlilies, this pretty stuff on the riverbank is Purple Loosestrife and Hemp Agrimony, and round the next bend there’s an Aldercarr with nesting herons. By doing so, you enrich people’s lives as well as your own.
Other than buying your book, can you tell us one tip that you give to an aspiring ‘bad’ botanist?
Just look. Look, and seek a name. These days you can use phone apps like Pl@ntNet which will have a decent shot at identifying plants from flowers, leaves, even bark. But mostly it’s about that mental shift: making it personal. Last year it was a nice little yellow flower, this year it’s the first Lesser Celandine of spring and your heart can rejoice.

Reconstructing how dinosaurs behaved from just their fossilised bones might seem like science fiction but is very much science fact. In Dinosaur Behavior: An Illustrated Guide, veteran palaeontology professor Michael J. Benton joins forces with palaeoartist Bob Nicholls to do what it says on the tin: write a richly illustrated introductory book on dinosaur behaviour that is well-suited for novices.
In Dinosaur Behaviour, Benton takes the reader through five main topics: physiology (which sets the pace for everything else), locomotion, senses and intelligence, feeding, and social behaviour (which includes courtship, reproduction, parental care, and communication). One or several ‘forensics’ boxes in each chapter introduce the basic gist of certain methods.
Reading through this book, it becomes abundantly clear that our understanding of dinosaur behaviour relies on two approaches. Though Benton does not mention it as explicitly as in his previous book The Dinosaurs Rediscovered, the first of these is new high-tech toys and tools. Examples include computed tomography (CT) scanners, normally used in hospitals, to make detailed X-ray scans of fossilised brains (so-called endocasts) and so determine brain anatomy.Or finite element analysis normally used in engineeringto model forces and stresses on jaws and teeth and so determine e.g. bite force. The second approach is ‘old-fashioned’ comparative anatomy and ethology: it pays to have a good knowledge of natural history when you are a palaeontologist. One example is the histological study of fossil dinosaur bones. Cutting thin bone sections and examining these under a microscope shows that some dinosaurs closely resemble mammals and birds, supporting the idea that smaller species were endotherms (‘warm-blooded’, i.e. generating their own body heat). Or take the microscopic study of melanosomes (pigment-containing organelles) in fossil feathers to determine colour in life. A final example is the comparison of footprints made by modern running birds with fossil tracks to determine things such as gait and running speed.
If you are well-versed in (popular) palaeontology, much of what is presented here will be familiar. Even so, I picked up interesting titbits. One example is a recent study of Psittacosaurus that describes a cloaca, the multipurpose orifice also seen in birds where the digestive, urinary, and reproductive tracts all open to the outside world. This suggests that dinosaur sex, for at least some species, was a matter of the appropriately named ‘cloacal kiss’ rather than the brandishing of reptilian genitals. Other insights fell into the embarrassing ‘I should have known this’ category. We tend to think of walking on two legs as something advanced because our mammalian ancestors walked on all fours, but for dinosaurs, it was the reverse; they started out bipedal and quadrupedality only evolved later in e.g. the large sauropods. Particularly interesting is the study by Kat Schroeder and colleagues who looked at fossil communities of theropods and noticed a so-called carnivore gap: there is a lack of medium-sized ones in the fossil record, even though there are medium-sized herbivores. One explanation could be that dinosaur eggs had an upper size limit, meaning that young carnivores hatched small and had an awful lot of growing to do. As they did, ‘they passed through a whole range of feeding modes, each step along the way acting like a different species’ (p. 137), effectively plugging the ecological niche of medium-sized carnivores.
Despite the broad range of topics, there are some curious omissions. The chapter on feeding e.g. discusses jaws, teeth, and the use of isotopes to determine diet, but not microwear analysis of teeth. What I found most surprising is that Benton does not introduce the concept of trace fossils or ichnology, their study. Yet, examples such as trackways (some possibly showing long-distance migrations), coprolites (fossil poop), and nests are all discussed here. Another surprising omission is that the two-page bibliography does not include most studies mentioned in the text, even though it references other technical articles.
Dinosaur Behavior is mostly very suitable for readers with little to no background in palaeontology. Benton explains even basic terminology (physiology, cannibalism) as he goes, though there is the occasional curveball. One example is the morphospace diagram showing a principal component analysis on page 131, which, I hope those with a background in statistics will agree, is a rather abstract way of visualizing data that requires a bit more explanation than is given here. Though the book is published by Princeton University Press, it has been produced by UniPress Books who can be considered the spiritual successor to popular science publisher Ivy Press. What this means is that information is accessibly presented in bite-sized sections on one or several page spreads, with long sections further divided using subheadings. The downside is that this restricts how thoroughly topics can be explored. Leafing through e.g. Naish & Barrett’s Dinosaurs: How They Lived and Evolved shows more nuance in its chapter on behaviour.
Finally, I have to mention the excellent colour and black-and-white artwork by Bob Nicholls that livens up the text. I loved the drawing of courtship in Confusiusornis on pages 168–169. Despite the overlap in topic, this is all-new artwork compared to Locked in Time. Other diagrams have all been carefully designed or redrawn, using colours where appropriate. The only design element that did not work for me was the choice of sans-serif font which made e.g. the letters ‘a’ and ‘o’ hard to tell apart.
Serious palaeontology buffs might find the contents here somewhat superficial, but overall, this is a handsomely illustrated book that offers an accessible introduction suitable for novices and possibly even curious high-school pupils. It would also make for a great gift.
The Little Owl, Athene noctua, is one of the most well-studied species of owl. Despite being widespread across Europe, Asia and North Africa, populations are now in decline, making studies of its behaviour and ecology all the more important. The revised second edition of The Little Owl, which vastly expands on the original, published in 2011, covers everything you could wish to know about the species. From its history, taxonomy and genetics, to details of its habits, diet and breeding, the wide-ranging text consolidates all of the current available knowledge, obtained both from the author’s personal experience and research, as well as scientific and conservation literature.
The authors, Dries van Nieuwenhuyse, Ronald van Harxen and David H Johnson generously gave up some of their time to answer our questions about the book, the issues currently affecting Little Owls globally, and their hopes for the future of this captivating species. The Q&A is also illustrated with some of the beautiful images from the book, all of which were created by scientific illustrator and graphic designer Joris De Raedt.
Firstly, can you tell us a little bit about yourselves and the work you are currently involved in?
Dries is a life-long owl researcher and statistician active in ecological method development and publication. He has authored five books on the impact of technology and statistics on the decision-making processes of organisations, and in particular brings his skills as a statistician to his ornithological work.
Ronald is Chairman of the Dutch Little Owl Working Group (STONE), and has been active in research on breeding biology and population dynamics within nest box populations and conservation of the Little Owl in the Netherlands and internationally for more than four decades.
David is Executive Director at Global Owl Project, USA and working since more than a decade on a demographic study of the Burrowing Owl (Athene cunicularia). He has worked in natural resource conservation for four decades and has written two previous books on owls, wildlife and fisheries.
Joris De Raedt is scientific illustrator and graphic designer

For anyone that enjoyed reading the first version of The Little Owl which was published in 2011, what new things can they expect to discover in this updated second edition?
The subtitle of the first edition was Conservation, Ecology and Behavior, the second edition paid special attention to Taxonomy, Population Dynamics and Management. Major improvements are the illustrations that were all created by Joris De Raedt. This allowed us to make compilations of photos of the subspecies and their habitats to obtain extremely detailed and standardised artistic plates. The fact that this edition is in colour allowed excellent drawings of the embryonic development, the evolution of nestlings in function of age and high quality distribution maps by country and globally. The global distribution map was revised with much more accurate data than even before, thanks to the internet and technological advances.
Plenty of new insights were brought in by Ronald on breeding biology, prey items and behaviour in nestboxes that were equipped with webcams. Photos led to video, and that led to online webcam data that was tagged with time, prey species and specific behavior by volunteers.
The final major evolution was the intensification of replicated experiments since the first edition. Crucial questions on the yellowness of the beak of the female in relation to breeding performance and feeding preference of female nestlings by females, and also in relation to the yellowness of the beaks of the offspring, led to major breakthroughs in our knowledge. Due to the publication of the first edition, the start of a pdf and citizen science website for data collection improved the international cooperation tremendously and facilitated access to international data bases of ringing data, geocoded pictures and vocalisations.
Historically the Little Owl has suffered due to intensive agriculture practices and abundant use of pesticides. Are Little Owls still widely affected by these issues, and do we yet have a clear idea of how they are likely to be impacted with the additional challenges posed by the climate crisis?
Little Owls are ambassadors of small-scale landscapes. In some countries they disappear due to intensification of the agriculture, while in other countries they disappear when farming is halted (grazing cattle disappear) and after forestation. Climate change is expected to have a positive impact on the species in the north and the east due to less snow cover. Increasing heavy rain during the breeding season, on the other hand, will probably have a negative impact on breeding success. Increase in desertification might not be an issue, as this typical Mediterranean species can even be found in the Sahara and the Arabian Peninsula. In Europe, most negative impacts comes from agricultural intensification, with an increase in maize leading to less grassland, increase in pesticides and rodenticides, increase in scale of the landscape with fewer parcel borders, fences or shrubs.
An important part of the book deals with management techniques that have proven to work over the long term. Reintroducing short grassy vegetation with commanding perches and provision of nestboxes can significantly help Little Owls to cope with modern agriculture. If conservation is started timely enough, this simple management can help preserve healthy populations. When densities drop too low, this might not be sufficient and, in combination with a lack of food, can lead to local extinctions.
What are the key ways in which Little Owls are surveyed? And how comprehensive is our knowledge of where they occur and their current population sizes?
The species is excellent for research due to its easy response to playback of vocalisations, historically mostly undertaken in western Europe but recently increasing in eastern Europe. Monitoring efforts have continued since the 1980s and offer a good view on population numbers. This has led to extra research on the possible impact of habitat deterioration, food availability and the increase of Stone Marten and Tawny Owls as possible limiting factors.
Since the first edition plenty of new local and large scale atlases have been published leading to a very detailed knowledge on the distribution and population numbers in Europe. The new EBCC atlas has distribution data at the 50 by 50km level, the 27 EU member states monitor Little Owl presence at the 10 by 10km level, and a number of local atlases have data available at the 1 by 1 km level.
Outside of Europe, the species is rather common but distribution knowledge remains anecdotal with population estimates largely based on local average densities and, in rare cases, on habitat modelling. More insights emerged from North Africa and the East (eg Iran and Pakistan) but much more work is still needed outside Europe. Hopefully this book can boost research in less well-studied countries, as many methods that have proven to be working simply need to be replicated elsewhere.
How effective have captive breeding and reintroduction projects been for the Little Owl so far? And is this approach likely to be an important one for their future conservation?
Not very effective. Some initiatives have been undertaken but with moderate outcomes. Reintroduction remains an emergency brake that rarely works. Supplemental feeding, provision of nestboxes and landscape improvements are much more effective, particularly when they are started in a timely manner. The key is not to wait too long before starting with small-scale management and to keep healthy populations, even in areas with intensive agriculture.
How likely are Little Owls to utilise artificial nestboxes?
Very likely, and this makes The Little Owl one of the best and easiest models for biological and conservation research. The ease of installing nestboxes with webcams and with predator protection allows data to be collected in an unprecedented manner, without special tools or tedious field work. People can observe the species seated at their kitchen table, youngsters can easily be involved in playback monitoring, nestbox maintenance and food supplementation, which eventually leads to experiments and dedicated citizen science. This make the species so special.
Finally, what’s next for you? Are there new books on the horizon?
Sure, Ronald and Dries will publish a non-scientific version of the book in Dutch for the 2000+ local volunteers to thank them for their tremendous help in collecting and digitising Little Owl data through conservation, management and ringing. David and Dries are currently preparing a similar book on the close relative of the Little Owl, the Burrowing Owl. Finally, Ronald is currently working on a book on all owl species that can be found in The Netherlands. We’ve still got some work to do.
The Little Owl by Dries van Nieuwenhuyse, Ronald van Harxen and David H. Johnson was published by Cambridge University Press in October 2023 and is available from nhbs.com.
An Identification Guide to Trees of Britain and North-West Europe is a fantastic new guide to 89 of the most commonly found and easily recognised trees in the region. Suitable for everyone, from the complete novice to the experienced naturalist, the book contains lively and interesting text from Dominic Couzens, complemented by Gail Ashton’s photographs. These show details of each species throughout the seasons as well as features that are useful for identification.
Dominic Couzens is a bird expert, nature writer and the author of over 40 books. He is also a regular print columnist and writes for Bird Watching Magazine, Nature’s Home (RSPB) and Water Life (WWT). He is passionate about communicating about the natural world and has a particular passion for writing about current threats to the planet and how they can be best addressed.
Gail Ashton is a photographer and writer with a passion for wildlife and invertebrates in particular. Well known for an incredible project where she undertook to photograph 500 UK invertebrates over the course of a year, she is passionate about encouraging everyone, young or old, to observe and appreciate the natural world.
We recently got to the chance to ask Dominic and Gail some questions about the book; about the process of compiling such a guide, the most fascinating things they learned in the process and their concerns for the future of trees in Britain and further afield.
Firstly, can you tell us a little bit about yourselves and how you came to be working together in writing this book?
DC: I am an experienced writer of natural history books and I’ve written a number of field guides, both to birds and mammals. However, in 2021 I came across Gail’s remarkable project to photograph 500 species of invertebrates in a single year. Her fabulous library was the perfect material for an insect guide, so we published An Identification Guide to Garden Insects in 2022. The project was a great success so here we are.
GA: I have always loved nature and one of my favourite ways to be outdoors is in woodland and forest. Studying insects brought me a new layer of fascination for trees as I found out just how many other organisms they support, and just how complex they are. Trees came on the back of the very-well received ‘Garden Insects’, and follows the same, beautiful format and layout.
There are numerous books available on tree identification. What do you think sets your book apart from other ID guides of its kind?
GA: Yes, there are a good number of outstanding tree guides out there – some of which I use myself. But they can be quite expansive and overwhelming, especially for those of us just starting our tree identification journey. This book is a perfect entry-level guide which introduces you to the different ways in which you can look at trees in order to recognise key features.
DC: It’s very different. For a start, while most tree guides even just to Britain have 300 or more species, we have cut this down to about 90. So it’s simplified and entry-level, including all the common wild species and some introduced ones – those that people might see. It is very far from technical and we have tried to make every species interesting and fun in its own right. We have included some really great facts about many of the trees.
I’m always fascinated by the process behind the compilation of such a comprehensive ID guide. What was the most challenging part of writing this book?
DC: Trees are complicated, with all the different parts from leaves to bark. As the writer of most of the text, even though I had a decent grasp of many British trees, it was always a challenge not to forget all the details. The other very difficult task was in selecting the species. We wanted to include all the species people will notice, including such non-natives as Magnolias and Eucalyptus, while including the bona fide wild trees. But we couldn’t find room for all the tricky willows, and in the end we just hope our choice chimes with people.
GA: Believe it or not, the biggest challenge for me was actually finding the trees. It sounds mad, because trees are everywhere, right? But finding that perfect tree to photograph took a lot of research, walking and finding, and then the light had to be right, so I would revisit trees multiple times. Some of the trees were quite difficult to find, such as the Wild Service and Mulberry, so a lot of detective work was required to pinpoint them. I also had to make repeat visits to capture them in all their seasonal phases. There are trees from all over Europe in this book -thousands of miles and hundreds of hours! But those are the lengths I’ll go to get a great photo.
I particularly enjoyed the fascinating facts that you included for each species in the book. Did you learn anything new or particularly surprising about any of the tree species covered over the course of your research?
DC: I learnt an enormous amount. Did you know that each Holly leaf lives an average of seven years, for example? I also love the fact that Monkey Puzzles are essentially adapted to cope with browsing Sauropod dinosaurs.
GA: I became particularly fascinated with the Ginkgo – a unique throwback to the very beginnings of life on Earth; a tree which is neither conifer nor broadleaf, but somewhere in between.
A big part of conservation and land management is knowing what species are where and how many there are. How much do we currently know about the trees present in Britain and their population sizes?
GA: According to Forestry Research, only 13% of the United Kingdom is currently wooded. That’s such a small percentage compared to a few thousand years ago. Our ancient woodlands have all but disappeared, replaced by farmland, urban development and plantations. Veteran trees are our most important, as they support more communities and sequester more carbon than young trees. It’s essential that our remaining veteran trees and woodland fragments are fully protected to ensure the health of our future natural landscapes.
DC: The recent Atlas of British Flora means that we are well covered in these terms. For some of the rarer trees, such as Black Poplars, we know how many individuals there are of each sex.
Within this guide you include information on the months when leaves, flowers and buds might be seen for each species. Do you have any information or a feel for how rapidly climate change is impacting these features?
DC: Trees are a good early-warnings system, and you don’t need to write a book on trees to see that many are coming out earlier than they used to – hazel catkins in December, for example. However, it was very difficult to get any accurate figures for the book because it varies so much from year to year, and we were also covering Northern Europe as well as Britain. However, we certainly got a feel for the potential problems. Birch catkins are coming out earlier in response to warming, but might be approaching the earliest they can cope with physiologically. Oak budburst will affect both the caterpillars that feed on it and the Blue Tits that feed on the caterpillars. On a wider scale, temperature changes will affect the whole distribution of trees through the country, with northern species retreating. We could lose some specialists such as Dwarf Willow, and the climate will also become easier for introduced trees.
GA: I think that trees are more difficult to use as indicators than insects as trees have a much longer generational turnover, and they don’t move; however monitoring the emergence of blossom and leaves in spring and the falling of leaves in autumn is a great citizen science tool to establish changing trends.
Are there any trees in the UK for which the future seems particularly bleak?
DC: There are well known problems for ash trees and to a lesser extent oaks, and we simply don’t know how far their respective diseases will go. But as a warning, remember that the Field Elm, in its various forms, used to be lowland England’s most abundant tree. Paintings by our forebears of the countryside were often dominated by elms – now they are a shadow of their former selves. And as mentioned above, the warming climate will impact upon our more northerly species.
GA: Ash dieback is currently decimating younger adult trees, though there is a glimmer of hope in that veteran ash are currently immune to the fungus. Juniper is in massive decline across the UK due to loss of suitable habitat.
Finally, what are you both working on now? Do you have plans for further books?
DC: We have co-written two books on insects recently: A Year of Garden Bees and Bugs and An Insect a Day, both of which are published by BT Batsford and are narrative-style books.
GA: I am currently working on upcoming books about invertebrates. I have an exhibition of my photos planned, as well as workshops, talks and podcasts.
An Identification Guide to Trees of Britain and North-West Europe was published by John Beaufoy Publishing in April 2024 and is available from nhbs.com.
In a break from many other books about the deep sea that talk about animals, Blue Machine focuses on the ocean itself, revealing a fascinating planetary engine. Equal parts physical oceanography, marine biology, and science history, topped off with human-interest stories, Czerski has written a captivating book that oozes lyricism in places.
Czerski is an accidental oceanographer, stumbling into the discipline from a background in physics. She boasts a long list of science communication credentials as a TV presenter, podcast host, columnist, public speaker, and author. This is a big book with chunky chapters but Czerski keeps the flow going by alternating between scientific explanations, fascinating experiments, and remarkable historical episodes. I find the deep sea endlessly fascinating and have been drawn ever further into oceanography through my reviews, yet something was always missing. This book has finally scratched the oceanographic itch I have long been trying to satisfy. How so, you might ask?

Start with that introduction. If you zoom right out, what sets a planet’s temperature, and with it the potential for life, is the balance between energy input from the sun and energy loss to the universe in the form of heat. From this grand, cosmic perspective, what the ocean with its circulating currents does is intercept some of that incoming energy and prevent it from immediately escaping again, instead “diverting it on to a much slower path through the mechanisms of the Earth: ocean, atmosphere, ice, life and rocks” (p. 5). From an energy point of view, “the Earth is just a cascade of diversions, unable to stop the flood but tapping into it as it trickles past; and the ocean is an engine for converting sunlight into movement and life and complexity, before the universe reclaims the loan” (p. 6). To me, this was such an awe-inspiring, attention-grabbing perspective on life on Earth, expressed so eloquently, that I wondered: is Czerski the new Ed Yong of oceanography? Tell me more, please!
What helps to understand the above perspective is the fact that the ocean is a vast three-dimensional environment that is constantly in motion, creating and maintaining differences at different scales. Heat and salinity create different layers of water that do not readily mix, meaning the ocean is stratified. This results in gigantic underwater conveyor belts and waterfalls. What makes these processes interesting is the shape of the container holding all this water: i.e. the continents and underwater topography. The local gravitational pull of the underlying rocks deforms the water surface, creating domes and holes over very large surface areas, a shape known as the geoid. Many more fundamental features and principles are described though she admits that she cannot squeeze the full complexity of the ocean into one book, treating other topics only briefly or not at all.
Admirably, Czerski is equally at home in the marine biology department and she features some wonderful critters here. True, these abound in all good popular science books about the deep sea, but her physics background allows her to show how the physical and biological worlds intertwine. A beautiful example of this is the mesoscale eddies that are spun off by oceanic gyres: large islands of rotating water that become temporary havens for all the plankton and fish that find themselves inside. The formation of these wandering buffets is such a regular phenomenon that large ocean predators such as tuna can make a living by roaming the seas in search of them.
Another captivating element is the many ingenious experiments, both historical and current, that she describes here. We almost developed a method to collect a long-term dataset on the global ocean’s temperature by bouncing sound waves through the seas, but the idea stalled after a successful pilot experiment in 1991. More successful is the Continuous Plankton Recorder Survey which has been running for the last 90 years, deploying mechanical recorders towed behind ships that use elegant internal clockwork to capture plankton on long strips of mesh and have gathered valuable long-term records.
The physical world also entwines with human history. One example is the narrow northern half of the Indian Ocean where gyres do not form but seasonal currents flow eastwards and westwards. The 14th-century Chinese Ming Dynasty used these to send expeditions of large ships laden with valuables up and down the coast of Asia and Arabia, trading goods for political influence and prestige. I was similarly captivated by the poorly known story of the 18th-century Scottish herring lassies: bands of female contractors who travelled south along the English coast each summer, following the southwards moving herring fleet. While the men worked the boats out at sea, the women were ready in ports and at beaches to gut, salt, and pack each day’s landing before the freshly-caught fish could spoil. Hard-working, skilled, and independent, they were decades ahead of most other women in Victorian England.

All of this is backed up by an attitude that, coming from a scientist, is refreshingly clued in to social issues. This becomes explicit in the final chapter where she addresses the environmental issues she has so far avoided. Though a popular mantra in politics is that we need to follow the science, she opposes this “for the simple reason that science does not lead. Where leadership comes from is a clear statement of values” (p. 381). Science can inform these, yes, but we have to decide what we care about for ourselves and our communities. Going down this path involves hard questions without simple answers, and nuance rather than binary “I am right, you are wrong” categories. It also means breaking with our perception of “the ocean as the end of a one-way pipe” (p. 289). There is no “away” on this planet for our trash. And it means breaking with a culture of infinite growth on a finite planet. Her thinking here is influenced by her contact with Polynesian cultures that value cooperation, openness, and teamwork, in contrast to the Western mindset of ownership and power play.
If I need to sound a critical note it is the lack of illustrations. Though the UK version features nice endpapers and a stunning cover, there are only two maps and two illustrations in the rest of the book. Especially some of the physical oceanography principles would have benefited from explanatory diagrams.
Blue Machine is an engrossing odyssey into oceanography. Czerski brings her substantial experience in science communication to bear on this topic and has written a transformative book. She brings to life the watery fabric of the ocean itself in ways I have not encountered before.
Springtime is often synonymous with rebirth, renewal and regrowth. As the Earth’s axis tilts towards the sun, our days become warmer and the snow starts to melt. The rivers and streams swell, air and ground temperatures rise, and we start to see new plant growth.
There are no fixed calendar dates for the beginning of spring. Ecologically, the start of this season relates to biological indicators, such as the start of certain animal activities and the blossoming of particular plant species. Phenology is the study of the timing of natural events from year to year, like the budburst of trees, the arrival of summer migrant species, the breeding bird season and the emergence of hibernating wildlife. You can find out more about the study of phenology in our previous blog post.
This is the first in our four part seasonal phenology series where you can explore a collection of ID blogs, books, equipment and events to make the most of the spring season.
Identification guides
Over the years, we’ve made a number of identification guides for UK species, many of which are active during spring. Here’s a selection that we think are particularly useful for this season:
What you might see:
You will likely start to notice the first flowering of many plant species, including Cuckoo Flower (Cardamine pratensis), Meadow Foxtail (Alopecurus pratensis), Bluebells (Hyacinthoides non-scripta) and Wood Anemone (Anemondoides nemorosa).
The budburst of trees, including Alder (Alnus glutinosa), Horse Chestnut (Aesculus hippocastanum), Rowan (Sorbus aucuparia) and Sycamore (Acerpseudoplatanus), with many also having their first leaves appear in March or early April.
Trees such as Hawthorn (Crataegus monogyna), Blackthorn (Prunus spinosa), Hazel (Corylus avellana) and Field Maple (Acer campestre) begin to produce blossoms and catkins. Spring blossom can start as early as February and last through to early summer.
The emergence of several insect species, such as Seven-spot Ladybirds (Coccinella septempunctata), Orange Tip butterflies (Anthocharis cardamines), Green Tiger Beetles (Cicindela campestris) and Dark-edged Bee-flies (Bombylius major).
The beginning of the nesting season for most European bird species, including Great Tits (Parus major), Tawny Owls (Strix aluco), Long-eared Owls (Asio otus) and Wrens (Troglodytes troglodytes). Great Crested Grebes (Podiceps cristatus) start their courtship rituals in early spring, with their elaborate dances, synchronised swimming, preening and ‘mewing’.
Many migratory birds also begin to arrive during spring, such as Chiffchaffs (Phylloscopus collybita), Swallows (Hirundo rustica) and Wheatear (Oenanthe oenanthe).
Reptiles and amphibians become more active during spring and into summer, coming out of hibernation and venturing to find food and breeding sites. Frogspawn, toadspawn and tadpoles also begin to appear during early spring and onwards.
A number of mammal species give birth during this time so that their young are born when resources are most plentiful. Badger cubs (Meles meles), which are mainly born in February, will begin to gradually emerge from their setts during spring.

Ponds, pools and puddles are a common sight in our landscape and play a very important part in sustaining wildlife. In Volume 148 of the New Naturalist Series, the authors provide a comprehensive survey of the variety of plants and animal life for which they are a habitat, and discusses the way in which they are used, their importance, and compares their major variations in life cycles. Ponds, Pools and Puddles makes an invaluable contribution to raising awareness of these popular, yet frequently underrated freshwater habitats and gives them the attention they rightly deserve.
Jeremy Biggs and Penny Williams work for Freshwater Habitats Trust, a wildlife conservation charity focused on reversing the decline in freshwater biodiversity. They have been involved in numerous research projects, publications and conferences on the ecology and management of ponds and other freshwater habitats.
We recently had the opportunity to talk to Jeremy and Penny about how they became interested in ponds, whether they think technological advances will play an important role in future pond research and more.
Jeremy Biggs
Can you tell us how you both became interested in ponds and pond life?
P: I had a wonderful early experience at primary school: we had a trip to a local pond in Southborough, Kent and caught a Three-spined Stickleback. The teacher brought a couple back to a classroom tank and I watched in amazement as the beautiful azure blue and orange male made a nest and fanned the eggs with his tail.
J: I was interested in wildlife from my teens, particularly birds, but it was at university (Royal Holloway, University of London) that my interest in freshwater was awakened. Crucial for me was an inspirational teacher – the late Dr Nan Duncan – who ran one of the best courses there was on freshwater biology.
I found your definition of a pond interesting as there appears to be so many ways of deciding what constitutes a pond. Can you talk us through the process that you went through to decide on the parameters for your definition?
P: After working on ponds for a couple of years it became clear that we needed an easy-to-use definition, particularly to deal with the inevitable question: is it a pond or a lake? It also had to include temporary ponds, which were hardly recognised in the UK at the time. So, at Freshwater Habitats Trust we went for an area-based definition because that’s easy to measure. We set 2 ha as the pond/lake cut off, as this seemed to best capture the difference between the two. The ‘wet for at least four months of the year’ is included as this is roughly the time needed for ponds to develop a wetland plant community. That means that you should be able go to a basin that’s wet or dry at any time of year and tell if it is a pond. In practice, the lower limit is a little flexible: we use 1m² to include tiny pools and garden ponds, but for practical reasons use 25m² for national counts of ponds where it’s impractical to count every little countryside puddle.
Penny Williams
It’s clear that the first national pond survey paved the way for gaining a more in-depth understanding of pond classifications, species, ecological preferences and more. What do you think the next step is in gaining an even greater understanding of ponds, and do you think modern, technological research methods will play a big part in this?
P: Current policy, legislation and general awareness of the importance of ponds now lags way behind our knowledge of pond ecology – so although there is still an enormous amount more to find out about pond biology, I think the greatest need is for knowledge that shows the importance and value of ponds for protecting freshwater biodiversity. For example, we need evidence about how high-quality pond creation and restoration can be used, at a landscape scale, to maintain healthy freshwater metapopulations, prevent extinctions and enable the spread of species that may be increasingly isolated by pollution and climate change. This is a real focus for Freshwater Habitats Trust, where we’ve been championing the importance of small waterbodies – and ponds in particular – for more than three decades.
Modern technology will undoubtedly play a part in this: DNA, and eDNA in particular, may be a game changer, although we are some way off from using it for the purpose that I would love: routine monitoring of all waterbodies (rather than just rivers) to get a real understanding of what is happening to freshwater biodiversity in our landscapes and how we can best address that.
New technologies are always exciting but, to be honest, I think the main thing we need at the moment is publicity, publicity, publicity. Widespread knowledge and appreciation at all levels of how wonderful these little waterbodies are.
J: More than a particular technological solution, what we really need is funding for ‘National Pond Survey 2’, led from a conservation perspective and, as we’ve been doing for the last 30 years, generating and testing the ideas that Ponds, Pools and Puddles summarises. There’s so much to learn here: are ponds still declining in quality? What’s the effect of pond management? How do ponds, lakes, streams, wetlands and rivers interact? What about the microbiota which we know next to nothing about (that is something eDNA will help with)? How is climate change affecting ponds?
It was fascinating to learn that there is a much greater variety of species found in ponds in comparison to river communities. How important do you think ponds are in the recovery of nationally scarce or Red Data Book species?
J: The very wide variety of nationally scarce and Red Data Book species found in ponds means that ponds are absolutely vital for the recovery of these species. The special virtue of ponds is that, with their small catchment, we can still find large numbers of very high-quality ponds in the landscape, or create new, near pristine, clean water ponds in areas protected from pollution. This is all much more difficult for streams, rivers and many lakes with their much bigger catchments. There’s no doubt that creating and restoring networks of clean water ponds could put many of our Red Listed freshwater species on an upward trajectory. Indeed, this is one of the aims of Freshwater Habitats Trust’s vision to build the Freshwater Network: to reverse the decline in freshwater biodiversity. This will see us creating a network of wilder, wetter, cleaner, more connected freshwater habitats, and ponds play a big part in this concept.

To what extent do you expect climate change to affect the ecological formation and chemical makeup of natural ponds in the future?
P: The effects of climate change on ponds are undoubtedly going to be complex, varied, unexpected and unpredictable. For example, in the Water Friendly Farming project, where we’ve been monitoring the same ponds for over a decade, a clear (but not predicted) result is that shallow ponds are being rapidly encroached by marginal wetland vegetation in dry years, and this vegetation persists so that open water is being lost. However, the effect differs: where ponds are grazed this has been beneficial, sometimes enabling uncommon plants like Orange Foxtail (Alopecurus aequalis) to spread to lovely new poached drawdown zones. In other cases, it has been sad to see little ponds with water buttercups be replaced by just wetland grasses like Sweet-grasses (Glyceria spp) and Creeping Bent (Agrostis stolonifera).
J: Climate change is going to have a big impact, but the effects are going to very difficult to predict. Ponds are so varied, it’s inevitable that their responses will be too. It’s possible to make sweeping generalisations (pollution impacts get worse, many temporary ponds disappear) but there’s a good chance these will wrong. It’ll be crucial to have a good set of observations of what is actually happening to ponds. In the meantime, the priority should be to use ponds to put as much clean water as we can back into the landscape.
What is the most interesting finding that you have come across while researching ponds, pools and puddles?
P: For me it’s undoubtedly been the opportunity to riff on my geological background and delve into the ancient natural processes that shaped ponds in the past – and which still has so much to teach us about ponds (and other freshwaters) today. For example, I love the fact that almost all of today’s wetland plants evolved in landscapes that had already been shaped by grazing and poaching processes for over 200 million years – no wonder many wetland plants benefit from grazing and the presence of muddy ground! And, at a time when many people (including scientists and policymakers) still undervalue ponds as man-made artificial features, some of world’s best-preserved evidence of early life in terrestrial landscapes (the Devonian Rhynie cherts in Scotland which are c400 my) reveal an environment that is full of ponds with the fairy shrimps and tadpole shrimps swimming amongst stoneworts.
J: For me, it’s been the chance to bring together so much information that we simply haven’t had a chance to publish anywhere else. With the amount of time it takes to publish research, we are extremely selective about what we write up in papers. Only the most important results ever make it into print. It’s also allowed us to look at groups we don’t work on so much ourselves (such as the microalgae) and see how these reinforce many of the ideas about ponds from the more obvious bigger plants and animals. It’s also nice to get into the book the truth that many of our biggest and most famous wetlands, like the Coto Donana in Spain, are actually massive pond complexes comprised of over 3,000 temporary ponds!

Are either of you working on any other projects that we can hear about?
J: Freshwater Habitats Trust is really busy at the moment! Amongst other things we are:
– Launching the Freshwater Network: this is our plan to restore freshwater biodiversity taking account of freshwaters, including the critically important small (standing and flowing) that make up most of the water environment but have been largely overlooked for 100 years.
– Developing the network in key regions to protect and restore freshwater biodiversity in some of our most important freshwater landscapes like the New Forest, The Brecks, in the catchment of the R. Thames and in the Yorkshire Lowlands.
– Working with colleagues in Europe and South America looking at pond biodiversity, ecosystem services and climate change as part of the EU Horizon 2020 PONDERFUL project.
– Beginning research on the value of pond buffer zones in a project for Natural England and assessing the role that eDNA can play.
– Creating thousands of new ponds with Amphibian and Reptile Conservation as part of the Newt Conservation Partnership – created for Great Crested Newts but with much wider benefits for wildlife and, critically, monitoring the effects so we can tell whether it’s really making a difference.
– Continuing catchment research which looks at all of the water environment. Fortunately more and more people are realising that in every landscape, small waters are a lifeblood.
– and so many others….

The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is the latest update of the Bat Conservation Trust (BCT) Guidelines and features new content on biosecurity, night-vision aids, tree surveys and auto-identification for bat sound analysis. Several key chapters have been expanded, and new tools, techniques and recommendations included. It is a key resource for professional ecologists carrying out surveys for development and planning.
Neil Middleton is a licensed bat worker and trainer. He is the Managing Director of BatAbility which offers bat-related and business skills development courses and training throughout the UK and Europe. He kindly agreed to take the time to write an article for us which will help ecologists and bat workers assess some of the key content and changes within the 4th edition of the Bat Survey Guidelines, and evaluate how this is likely to impact you, your colleagues and your business.
I have been asked to write this blog for NHBS regarding the recently published 4th edition of the BCT Bat Surveys for Professional Ecologists: Good Practice Guidelines. Straight away I feel I should say that, broadly speaking, we (BatAbility) are supportive of the overall spirit of intent that these new guidelines are seeking to achieve.
The contributors to the finished work and the editor of the final draft will have, I’m sure, had much debate about the final wording of the guidelines. It certainly cannot have been an easy task to come up with approaches that a broad range of experienced people, each with different backgrounds, were able to fully agree upon (or at least not disagree). In addition to which, these guidelines need to cater for all the component parts of the UK, where differences in legislation, planning, licensing etc. apply.
What follows are my thoughts on why you need to be up to speed with what’s happening. When I discuss some of the points you need to be aware of, it’s not that I am criticising or disagreeing with what has been produced, it is more that I am encouraging you to think about things that may not immediately be apparent when it comes to impacting (positively or negatively) upon your daily business operations.
Broadly speaking, these Good Practice Guidelines are what we all need to be referring to now for guidance and, barring any new properly released formal material direct from BCT (i.e. it doesn’t matter what someone says on a social media post or during a webinar) that either updates, changes or gives additional explanation to what is in the 4th edition, this is where we, as a community, are at. BCT have confirmed that a few changes to the text will be made by way of an amendment document and this, in conjunction with printed Q&A material resulting from BCT webinars (November 2023 and February 2024), will prove to be essential complimentary reading for everyone relying upon these guidelines during their day-to-day work.
At this stage, I feel that it is also important to say, and BCT have been very keen to emphasise this point (e.g. during their webinars on the subject), that the guidance is very clear about deviating from its approaches where specific cases and/or experienced, professional judgement suggests that a different approach can be taken for good reason, provided that it is fully disclosed and discussed within generated outputs (e.g. reports going to local planning departments). The material produced is described as ‘guidelines’ after all, and should not be used prescriptively when common sense, good scientific rationale or proportionality, as examples, suggests otherwise.
These updated guidelines were keenly awaited by bat workers for some time leading up to their publication.The driving force behind the update was thought mainly to be the integration of Night Vision Aids (NVAs) into our bat survey approach, as initially described within an Interim Guidance Note published in May 2022 and covered in this article on the BCT website.
I mention this for two reasons. Firstly, it’s what I feel almost everyone was genuinely expecting. Secondly, these revised guidelines don’t (as anticipated rightly or wrongly!) fully address some of the specific aspects of where the NVA debate is going to finally arrive. Regarding this aspect of bat work, the finer detail around this matter is now being tackled by a review panel, and BCT will inform us as/when they are in a position to do so. In the meantime, the Interim Guidance (2022) remains as an additional, essential point of referral. Having said that, within these new guidelines there are regular pointers, reminders and requirements that NVAs should be incorporated within survey design.
So, why do we need to pay any attention to these new guidelines? If they are not telling us about the specifics of the NVA approach, then you may very well think that there’s not much value in getting your own copy and reading through, yet again, what was there before. Yes, you may very well think that. Yes, you would be very wrong.
There is so much in here that is going to make your life as a bat consultant different to how it was up until last year (2023). There are undoubtedly elephants potentially in some people’s rooms. But an hour after sunset when it’s too dark to see, some people may not be aware that elephants lurk (well not unless they have an NVA, and it’s pointing in the right direction). There are resourcing implications, cost implications, tendering implications, health and safety implications – there are all of these and more that you need to be aware of. And by implications I mean a mix of positives and negatives. It is a classic situation whereby in solving a range of issues and making clarifications on others, new issues and opportunities inevitably arise.
From a surveyor’s point of view, the dreaded dawn work is mostly redundant, although I feel there are still going to be occasions from a bat behaviour point of view, and from a health and safety point of view (e.g. working within busy town centre areas) where dawns could still occasionally be a better, or even a desirable approach. The guidelines certainly don’t say you should never do a dawn survey again, full stop.
From a business owner’s perspective there are matters that will need serious consideration and budgeting for. This could impact (again negatively or positively) upon your turnover, your approach to tendering, resourcing, the deployment of staff and equipment, as well as the careful balancing of your team’s time at their desks versus time in the field. All of this, of course, needs to be considered against the benefits to bat conservation. The challenge on the business model is not necessarily a bad thing, provided you are fore-armed and have seriously thought through how these changes impact upon your organisation.
Please don’t construe that I am not supportive of what these guidelines are seeking to achieve. In many respects, from a conservation perspective, I feel things have moved closer to where they should be. Balanced against this, however, I urge you to be aware that you need to get your head around the new approaches as a matter of urgency, and build into your day-to-day workings methods of adapting to the changes.
There is neither the time nor the space to cover it all here, and to do so would merely be to repeat what was contained in the guidelines in any case. What I am seeking to do is alert you to the fact that, despite how much you may have seen on social media etc. relating to the NVA debate, there are arguably equally as BIG matters contained within the new edition that don’t relate to the use of NVAs.
Here are some key points of where things have really changed, in my view:
Dawn surveys are pretty much redundant, as we are now pressed to doing dusk surveys with NVAs. This is great from a work-life balance, but it also removes up to 50% of the previously available time slots on your survey calendar.
NVAs are to be deployed on pretty much every emergence survey, covering the survey subject as fully as possible, with the associated implications for reviewing all that footage and storage of data. Video footage is much larger than the pure audio that you will have been accustomed to.
A licenced bat worker is required to be present for any field work where a licensable situation could occur, no matter how likely or unlikely, be that structures or trees. Following the definite statements in the 4th edition, there is no longer any ‘wiggle room’ on this issue.
Bats and Trees – aerial assessment (be that by ladder, rope or MEWP) is pretty much the desired approach, meaning that this will be a greater part of these jobs and, in conjunction with this, licensed bat worker(s) will need to be present.
Due to the increased requirement for licensed bat workers to be present far more often than previously was the case, and the increase in tree climbing work where licensed bat worker(s) should also be used, there are resourcing implications that need to be considered when it comes to training in these areas. It is important to be aware that not every licensed bat worker within a business is either capable of or desires to climb trees. Also, in some business models, the licensed person/people are in more senior positions where their presence in the field conflicts directly with the role they are being asked to perform for the business (e.g. team management, client meetings, tendering, business process improvement). So, for some businesses, depending upon their current resources of licensed bat workers, there may need to be a rethink.
What I have described above is most definitely not the full suite of changes, but hopefully it’s enough to demonstrate that you need to get on top of what’s in there.
The key message is, if you haven’t already got yourself a copy and read it through in detail, then as a matter of urgency you should do so. Then you will be able to consider how you are going to achieve what is required.
