As an island nation, the shoreline around the British Isles has a special significance for many of us. Whilst we might feel at home combing rockpools or wandering the shoreline, the world of plankton remains far more elusive.

In Seashore Plankton, Julian Cremona, author, educator, and naturalist, reveals the fascinating microscopic life found in our coastal waters. Perfect for naturalists, ecologists, and students, Seashore Plankton is the first practical, shore-based guide to collecting and identifying marine plankton. Packed with over 400 vivid photographs and clear advice on sampling and microscopy, the book opens an unseen world while highlighting the ecological importance—and vulnerability—of these tiny organisms.

Ahead of the publication, we had the opportunity to talk with Julian about the book’s development.

Firstly, can you tell us a little bit about your background and the reasons for writing this book?

I have always had a fascination with biodiversity in all ecosystems, and have been collecting marine and freshwater plankton since the late 1970s. After nearly sixty years of educating people in seashore ecology, I know how important plankton knowledge is to fundamentally understand the complexity of the shore. There are a few good books and papers about identifying offshore planktonic species, but they are scientific works and do not look at collecting, studying, or interactions between organisms. Most importantly, there are none dedicated to the seashore.

Plankton collected directly from the seashore is different from that taken offshore. There is some overlap and so the identification books that exist are useful, but there is nothing out there that is specific. The water lapping over the seashore has a more biodiverse variety of organisms compared to offshore samples. This is because the plankton arrives from three or four different sources: rivers and estuaries, invertebrate larvae released from the seashore, organisms washed by wave action into the plankton and life brought in by wind and tides from the ocean. I felt a whole new approach was needed to make seashore plankton accessible and try to unravel its complexity. In particular, I wanted to describe how to collect samples from the shore rather than a boat, explain how to look at them, and introduce the huge array of organisms found on the shore and how they link with the life that we can more easily observe.

I have written a number of books on the seashore, but this was the most difficult. Part of the problem is that you are writing about creatures that few people have seen or can comprehend, especially because most do not have common names. It is surprising how many people can be expert on seashores but still be unclear on the microscopic plankton that is an essential part of the ecology.

In the introduction, you discuss how difficult it is for us as terrestrial creatures to understand the ocean as a complex ecosystem. How has your understanding of the seashore as an ecosystem changed throughout your study?

Whenever I stop near the coast and look out at a vast expanse of blue, I invariably think of the trillions of organisms out of our sight, to which most people would not give a thought.

Over the years there have been subtle changes in how I study the seashore. In the last decade or so I have tried to bridge the gap between the organisms we see with the naked eye, like, say, sea anemones, and the microscopic detail of the plankton. For example, small pieces of glass and other materials placed on the shore will quickly become colonised by spores and larvae from the plankton over time. By removing these pieces to observe the developing biofilms under low magnification and photographing changes, it has given me a better insight into the relationship between substrate, tides and the organisms. The change in the first few weeks is amazing with the growth of bacteria, forming long chains, enabling diatoms and protists to begin colonisation. The more I observe, the more I realise how little we understand.

You point out the assumption that specialist or expensive gear is required to observe seashore plankton. How does someone interested in coastal plankton get started?

Collecting from the shore requires different considerations. Trawling from a boat is easier, for one thing. To collect a sample, a large volume of water needs to be filtered for microscopic life, and there are different ways to do that. Buying a good net to pull through the water is the best option, but then finding a suitable place for sampling can be a challenge. All this is covered in the book: where to sample, and how to choose and use the net. An expensive microscope is unnecessary, and the book tries to give some suggestions for observation, but you will need some way of magnifying the creatures found. Most other items you need are inexpensive and may well be in your home already.

I was recently amazed to learn the role that phytoplankton play in oxygen production. What else has the study of plankton revealed about oceanic and planetary systems, and how are plankton linked to human and planetary well-being?

One misnomer, that one sees regularly stated, is that every second breath you take is oxygen from phytoplankton. For sure, 50% of the oxygen produced on earth is from phytoplankton but mostly that stays in the sea and is used by the organisms living there. We are still reliant on terrestrial sources of oxygen. The study of plankton and links to our wellbeing is a huge topic and only briefly discussed in the book. If I choose one example, it is probably how common species within marine plankton have an essential role in sequestering carbon and taking it to the bottom of the oceans. So few people in the world realise how important the sea is in determining our weather patterns, and plankton is part of that – a reason why plankton blooms are monitored by NASA from space.

A large portion of the book is devoted to the dizzying array of organisms that can be found within the plankton. Is there a group you find yourself particularly drawn to?

Marine worms, the polychaetes, have species that permanently live in the plankton that I love finding. Huge numbers of other worm species live in sediment or on rocky seashores and liberate amazing larval forms that develop and grow for weeks in the plankton. Some, like the syllids, have a weird sexual reproduction called epitoky where the worm on the shore grows a special new ‘worm’ (called a stolon) on the end of the body that can be male or female. These swim off into the plankton to find a mate and disperse but eventually die as they have no gut. I love the diversity and beauty of the polychaetes. One of the most common larvae found are those of Polydora, which change dramatically over time and are super to watch, with real character.

The final chapter discusses the human induced stressors on the ocean ecosystems and plankton populations, from pollution to climate change. Can you give us an idea of some of the changes, and have you been able to observe any over the course of your study?

The most obvious issue is that of the warming sea along the coast. We can surmise some of the problems, like the increase in jellyfish, but will the synchrony between copepods (important crustaceans as prey for fish) and the organisms they feed on change? We know this is happening on land, for example where nesting insectivorous birds may produce young before the appearance of insect prey. Acidification of the oceans was predicted many decades ago, but already problems are developing where some mollusc larvae are failing to develop shells properly.

In the last few years, we have seen the sea around Milford Haven, where I sample, reach record high temperatures. There are two noticeable long-term anecdotal changes I have noticed in the last decade. One is the increase in ‘gelatinous plankton’, not just jellyfish but also small hydromedusae and siphonophores. The most well-known of the latter is the infamous Portuguese Man-o’-war, but there are also many much smaller, completely transparent (and thus difficult to see) forms, that congregate in huge numbers during the summer. The second observation is in the composition of plankton. While many species occur year after year there are steadily more warm water species appearing as distribution ranges move northwards.

And finally, do you have any other projects on the horizon?

As I said at the start, I enjoy observing all ecosystems. One that has always fascinated me is the saltmarsh. These are great breeding grounds for microscopic life. Sometimes this can temporarily appear in marine plankton, and I have been drawn to sampling the surface mud in all areas of the marsh as well as the saltpan pools that vary so much in their salinity. This is an area I am developing and intend to spend more time studying.

Author interview with Peter Sutton: Field Guide to the Grasshoppers and Allies of Great Britain and Ireland

The Bloomsbury Wildlife Guides series has consistently set the standard for invertebrate identification, combining practical, readable text with meticulous illustrations by Richard Lewington. The latest instalment tackles the grasshoppers and relatives, a diverse and fascinating group undergoing rapid change in Britain. With flawless production quality and clever features such as QR links to audio recordings, this book provides a complete picture of the identification and dynamic lives of these fascinating insects.

We recently had the pleasure of speaking to author Peter Sutton about the story behind the book, changes in the British fauna, and what readers can expect from the new guide.

How long have you been studying these insects and what first led you to take an interest in them?

I have been studying this group of insects since I began to catch grasshoppers half a century ago at the age of seven, on a dry grass verge that ran alongside a railway line in West Sussex. I was drawn to them by their song, their amazing ability to jump and fly, and the bright orange-red abdomen of the males. This led, in a bramble thicket at the same site, to my first sighting of bush-crickets, and then on to learning about all of the British species when I found Dr David Ragge’s Grasshoppers, Crickets and Cockroaches of the British Isles at Crawley Town library. It was this authoritative and fascinating text that informed all future journeys to the New Forest, the Isle of Purbeck, Chesil Beach, and anywhere else that was likely to reveal the orthopteran riches of these islands.

How did the new field guide come about?

I first had conversations with Andrew Branson who floated the idea of a field guide almost 20 years ago. At the time, this potential project was put on hold because there was a lot of activity by other writers who were working on publications about the Orthoptera. However, it soon became clear that there was a genuine requirement for a publication that covered all of the orthopteroid insects including the earwigs, stick-insects, cockroaches and mantids. Björn Beckmann and I were busy working on an updated distribution atlas when we got the call from Bloomsbury saying that Richard Lewington had agreed to illustrate a field guide for this group of insects. With a bit of further negotiation, we arranged for the field guide to include distribution maps for all of the native species, as well as naturalised species that had established viable outdoor colonies, and with this agreed format, the project went ahead.

Can you give us a taste of what’s covered within the species accounts and elsewhere in the guide?

The 65 species accounts have the following format: a detailed Description of adults highlighting key identification features; Measurements (total length, wing length, ovipositor/cerci length, eggs/ootheca size); Variation (colour and pattern forms/wing length; Similar species; Lifecycle and habits including colour-coded phenology charts; a description of Song including a visual representation (sonogram) and a QR code that allows the reader to hear the song when scanned using mobile phone technology; Habitat and distribution (including, the 48 for native and outdoor naturalised species, a small generalised map in the account and a detailed 10km square map in the appendix); Conservation (for species that have IUCN threat status); and details of How to find this species. These accounts also include illustrations of male and female adults and where useful, nymphs, as well as additional photographs of adults, nymphs, and varieties.

A comprehensive and well-illustrated Introduction (over 300 photographs have been used to illustrate this field guide) is followed by chapters on Studying and recording orthopteroid insects, and a Regional guides section written by county and regional recorders, which provides an assessment of species that are likely to be found in Great Britain and Ireland, including the Channel Islands, Isles of Scilly, and the Isle of Man.

An illustrated ‘At-a-glance’ guide and key to the orders provide a helpful starting point to begin the process of identification, followed by detailed identification keys in the introduction to each order of insects, which include many useful labelled diagrams and photographs.

At the end of the book is an assessment of Potential new orthopteroid species, a comprehensive Checklist, a list of Useful resources, and a Glossary of terms, followed by the detailed Distribution maps.

One of the many standout features of this guide is the beautiful artwork by Richard Lewington. With such a varied group of insects, how did you decide what to include in the illustrations?

Richard, as with all of the field guides that he has worked on, has done a spectacular job of illustrating this group of insects and the field guide contains more than 180 artworks. As a rule, adult males and females are illustrated for each species profile, unless they are all but indistinguishable e.g. American Cockroach, or parthenogenetic e.g. stick-insects and Surinam Cockroach.

Other significant colour forms (notably brown forms of otherwise green bush-crickets) have been included, and key features, such as the dorsal view of the head and pronotum of grasshoppers, and the cerci of earwigs, have been provided in colour. Key identification features also appear in the species profiles and illustrated keys as monochrome labelled diagrams.

This is the first book since Marshall & Haes’ 1988 Grasshoppers and Allied Insects of Great Britain and Ireland to cover all orthopteroid insects in Britain and Ireland. What’s changed for these insects in the 30+ intervening years?

In a relatively short period of time, we have moved from what was an essentially stable fauna, where new species were recorded as a result of more rigorous field work e.g. Heath Grasshopper, and taxonomic inspection e.g. Cepero’s Groundhopper, to a more dynamic situation where new species have, and are likely to continue to become, naturalised through climate induced migration e.g. Large Cone-head, and human-assisted introduction e.g. the Garden and Variable cockroaches. In all, ten new species have become successfully naturalised in Britain since the first species, the Southern Oak Bush-cricket, arrived in England in 2002, and three new species have been added to the Irish list, representing significant increases to the British and Irish fauna.

Another remarkable change, which had already shown signs of beginning when Marshall & Haes was published, has been the spectacular climate-linked spread of certain species (e.g. Roesel’s Bush-cricket, Long-winged Cone-head, Slender Groundhopper) across England, Wales, and for the Short-winged Cone-head, Scotland, and possibly Ireland. Conversely, there is tangible evidence to show that the Common Green Grasshopper, and possibly the Common Groundhopper, have experienced range contractions as drier conditions no longer cater for the hygrophilous requirements of their eggs.

There are many other points of interest. Many of the species that were introduced in imported food, such as the Cuban Cockroach, are no longer seen as biosecurity measures have improved, whereas the less regulated horticultural trade appears to continue to import alien species with worrying regularity, and has undoubtedly been the source of the recently naturalised Garden Cockroach and Variable Cockroach populations that are now well-established at sites across England. Improvements in pest control, together with more efficient heating systems, have also successfully eradicated once familiar species like the Oriental Cockroach, and of particular note has been the disappearance of the House-cricket, whose populations have additionally been lost through its susceptibility to the Cricket Paralysis Virus (CPV).

From your experience as the lead on the recording scheme for Orthoptera and allied insects, how has interest in these insects developed over the years and how do you hope the book will contribute in the future?

There is no doubt that the rise of the internet has played a major role in popularising the orthopteroid insects. It has facilitated the establishment of recording groups and allowed them to communicate rapidly with each other to share details of their finds, such as the important evidence of breeding for the Praying Mantis in the New Forest and the Isle of Wight this year. It also allows knowledgeable members of the group to rapidly confirm the identification of species. Record submission to the Recording Scheme is now easier, notably through iRecord, and the development of the mobile phone Grasshopper App means that species can be identified more easily in the field using illustrations of key identification features and song recordings.

In this context, the main contribution of this field guide is to provide information that will allow species that were previously not found in Britain and Ireland to be correctly identified. This is particularly the case for species like the two sickle-bearing bush-crickets and the newly naturalised cockroaches, for which there was previously very little information to work with.

As to role that this field guide will play in the future, as per the reasons provided in the Introduction, there is no better time to study the grasshoppers and allies. It is hoped that this comprehensive, technically useful, and aesthetically pleasing guide will inspire a new generation of enthusiasts to study this remarkable and often spectacular group of insects.

Author interview with Kate Bradbury: Wildlife Gardening for Everyone and Everything

Kate Bradbury is an award-winning writer specialising in wildlife gardening. She is the author of One Garden Against the World and The Bumblebee Flies Anyway, edits the wildlife pages for BBC Gardeners’ World Magazine, and writes for the Country Diary column in The Guardian. Beyond her writing, Kate has also appeared on TV, with her garden and work featured on BBC’s Springwatch, Autumnwatch, and Gardeners’ World.

With the release of a fresh new edition of Wildlife Gardening for Everyone and Everything – an inspiring and practical guide to making the most of your wildlife gardening projects – we had the perfect excuse to catch up with Kate.

What triggered your passion for wildlife gardening?

I think it was always there… I have always been a gardener, but in 2005 a bumblebee made a nest in an old duvet in my ex’s back yard, and the neighbours complained, and we had to move it. I got in touch with Bumblebee Conservation Trust and learned how to do so safely, and my journey to grow plants for wildlife began!

What inspired you to release a new edition of Wildlife Gardening for Everyone and Everything? Could you highlight the most important updates or changes since its previous edition in 2019?

The thing about wildlife gardening is that it’s based on science and ecology, so any updates in what scientists and ecologists know about wildlife and the habitats we create for them, must be reflected in the advice on how to go about creating habitats – we want the best for wildlife after all!
Two important differences include what we feed to hedgehogs, as mealworms, peanuts and sunflower seeds are now thought to be bad for them, and the new debate about whether we should be feeding birds at all: I explore the pros and cons in the book.

What are the key tricks to get people excited about wildlife gardening?

Passion is the only way in, and it’s not a trick! It will make you happy and lead to a lifetime of loving, and being fulfilled by wildlife. But, if you need convincing that creating homes for bugs etc. is important, focus on hedgehogs or birds, or butterflies – something that you really connect with. Cater for that one species or group and see where it takes you.

What key advice would you give to a beginner wildlife gardener?

Just enjoy it! Don’t make too many compromises, remember it’s your garden too. That way you can create wildlife habitats while still caring for a garden that works for you, too – that’s the key to long term relationships with the species you share your garden with.

From your experience, what are the main challenges people face when creating a wildlife-friendly garden, and how can they overcome these challenges?

A lot of people worry about having a messy garden, or that they will attract rats, or that they just won’t do it right and will somehow harm the wildlife they’re hoping to attract. But, really, if you focus on relaxing, having fun and perhaps concentrating on one or two species, you can’t go wrong. Wildlife gardening is a journey, see what works for you!

Since you began promoting wildlife gardening, what changes have you observed in the public’s attitude towards it?

It’s been huge, actually. When I first started writing about bees and creating habitats, there was a lot of pushback, especially on elements like letting areas of grass grow long or growing native plants. Now there’s a much greater awareness of the needs of our wildlife and a greater desire to help the cause. It’s been really lovely to witness.

What are some of the biggest misunderstandings about wildlife gardening? Additionally, could you share some of the most common mistakes you’ve seen people make?

There’s a thing about messy gardens that irritates me – first the idea that wildlife gardens have to be messy but then the concept of messiness in itself. The best wildlife gardens mimic the natural processes of the woodland edge, so feature habitat piles including log and leaf piles, open compost heaps, native plants and a source of water, and aren’t pruned or cut back too much. Is that messy? I don’t think so!

How concerned should we be about invasive plants and animals in our gardens? What criteria can we use to tell which species help our wildlife gardens and which might cause harm?

I wouldn’t get too caught up in fear over invasive plants and animals (usually insects). Just avoid buying invasive plants (There are lists to browse online.) and get in with creating habitats! That’s the main thing.

Are there any memorable success stories you can share where wildlife gardening has made a real difference to local ecosystems?

Every habitat you create is a success story, but I’m especially happy to have the Garden Tiger moth, which has declined by around 96% in the south-east in the last 40 years, breeding in my garden. That feels like a big win.

Book review: The Secret Lives of Dinosaurs

***** Beautifully presented

Back in 2021, palaeontologist Dean Lomax impressed me with Locked in Time, a popular science book that looked at the behaviour of extinct animals as revealed by a selection of extraordinary fossils. Showing that there is more to be said on the topic, he now returns with The Secret Lives of Dinosaurs, which features another tranche of remarkable fossils. More than just a sequel, this book improves on its predecessor in several respects.

Since the publication of Locked in Time, there have been several other popular books on trace fossils and the behaviour of extinct animals. I reviewed Michael J. Benton’s introductory guide Dinosaur Behavior and David Hone’s excellent Uncovering Dinosaur Behavior, while Jean Le Loeuff’s What Did Dinosaurs Think About? is on my radar. Anthony J. Martin, whose 2014 book on trace fossils, Dinosaurs Without Bones, merits mention in this context, returned in 2023 with Life Sculpted to look at trace fossils of bioerosion. Collectively, these books show what else you can do with this topic, so I was curious to see what tack Lomax would take this time.

Undeniably, The Secret Lives of Dinosaurs has all the appearances of being Locked in Time II. It follows the same formula: previously, we got 50 case studies under five subject headings; now we get another 49 case studies under eleven headings. Furthermore, in his introduction, Lomax adds that “You might even consider this a sort of sequel” (p. 1). Finally, when I interviewed Lomax back in 2021, he mentioned originally wanting to discuss 100 fossils but having to cut his selection in half. One fossil he regretted having to omit was the arthropod Aquilonifer spinosus, nicknamed the kite runner, that was found with its offspring tethered to its body by long filaments. That fossil here appears in chapter 3 as “Tethered Toddlers”. However, calling this book a mere sequel would be doing it a disservice: this is more than a compilation of the leftovers that missed the cut last time.

For starters, we can establish that the three strong points I highlighted last time are all still in effect. First, Lomax reiterates that not all interpretations of certain behaviours are uncontested. Though we have interesting evidence of swimming tracks made by small theropods, sauropod swimming tracks are more controversial, while palaeontologists continue to discuss whether the rocks swallowed by marine reptiles (gastroliths) acted as ballast or digestive aids. Second, Lomax continues to shine a light on the inner workings of palaeontology. When an excavator bucket cuts right through an elasmosaur fossil, he brushes this aside with a casual “These things happen” (p. 240). Several case studies show how certain fossil discoveries play out over decades of intermittent study and attempts to relocate historic dig sites. Third, Lomax continues to mix entertaining popular science writing that has lost none of its enthusiasm with gentle education. He still defines terminology on first use and continues to stress the relevance of studying animal behaviour today to understand animals of the past.

More importantly, The Secret Lives of Dinosaurs improves on its predecessor in several respects, most noticeably in its lush presentation. The publisher has thrown its full weight behind this book, printing it in colour on thicker paper stock. It is thus noticeably heavier than Locked in Time, even after accounting for its extra 54 pages. Bob Nicholls’s excellent artwork—and there is a lot of it—really pops this time around, while the numerous photos and illustrations of fossils are crisp and informative. One outstanding example of how this is put to good use is the section on the fossil evidence for caudal autotomy, i.e. the voluntary amputation of one’s tail, shown by many small reptiles today as a defence against predators. Page 117 shows two colour photos of a lizard fossil under visible and UV light, the latter revealing a regenerated, cartilaginous tail invisible to the naked eye. Another change is that all entries are slightly longer, increasing from an average of 4–5 pages to 5–7 pages. On several occasions, Lomax uses this to detail the chain of reasoning by which scientists eliminate competing explanations to arrive at their conclusions. How do you tell apart stomach contents from fossil embryos when a species is a known cannibal? Have we found evidence of ammonite eggs, or did another cephalopod repurpose empty ammonite shells? And how do you conclude that a combined trackway is evidence of two giant millipedes mating?

Finally, I think that more of the same, when done well, is not a bad thing. On that note, Lomax has again curated a collection of truly exceptional fossils. Though at least two case studies were discussed in Uncovering Dinosaur Behavior and that giant Tyrannosaurus rex turd featured in King Tyrant, much here was new to me. Never mind the title, this is about much more than just dinosaurs. Lomax jokes how one of the best ways of surviving in the fossil record is being eaten, as evidenced by descriptions of a new lizard and a new beetle species from respectively Microraptor stomach contents and coprolites from (likely) Silesaurus. And while the present often informs the past, sometimes the past reveals something about biology today, such as the discovery of an amber-encased fossil of a tiny springtail hitching a ride on a mayfly. Conventional wisdom had it that springtails spread via oceanic currents or aerial plankton; now we can add phoresy (the act of attaching oneself to a host organism to catch a free ride) to that list. Or take the footprint on a coprolite, showing that crocodilians, too, sometimes stepped in it. Or the scars on a plant leaf that, according to one team of researchers, exactly match those made by zombified ants today when they clamp their jaws down on a leaf vein just before dying and sprouting a fungus from their head. Yep, an unusual example of fossilised evidence of ant-fungal parasitism! It is hard to pick favourites with such a remarkable list of fossils.

How Lomax got Slash from Guns N’ Roses (!) to provide a blurb for the book? I am sure there is an interesting story here, but his praise, placed prominently on the cover, is one that I can echo. If you liked Locked in Time, this book is a no-brainer, improving on the execution of the concept. If you would like a novel kind of popular palaeontology book, whether for yourself or for somebody else, this book also comes highly recommended.

International Day of Women and Girls in Science 2026: Interview with Dr Antje Steinfurth

To celebrate International Day of Women and Girls in STEM we chatted with Dr Antje Steinfurth, Conservation Scientist at the RSPB.

Antje has been studying Penguins for over two decades and is the RSPB’s resident expert on these birds. Antje currently focuses on the UK Overseas Territory of Tristan da Cunha, a very remote, volcanic island in the South Atlantic which is a haven for many globally rare animals and plants, including shearwater species and an endemic albatross. Antje’s penguin expertise is helping to protect one of the islands’ most charismatic but threatened species, the Northern Rockhopper.

We had the pleasure of asking Antje a few questions about her extraordinary career and the importance of International Day of Women and Girls in Science.

Can you share a bit about your background and what inspired you to pursue a career in conservation science?

I have always been drawn to nature and wildlife, which led me to study Biology at the University of Göttingen in Germany. Wanting to focus more on marine ecology, I later moved to Kiel University, where I completed my Diploma in Biology and, subsequently, a PhD in Marine Zoology.

Increasing awareness of the threats facing biodiversity motivated me to use science not just to understand wildlife, but to actively help protect it. After albatrosses, penguins are the second most threatened family of seabirds, with currently ten of the 19 species being of global conservation concern. During my Diploma studies, I worked on the foraging behaviour of Magellanic Penguins in Argentina. What I didn’t realise at the time was that penguins would accompany me throughout my professional life – literally leading me from the equator to Antarctica.

Supported by a German Academic Exchange Service (DAAD) scholarship, my doctoral research took me to the Galápagos Islands, where I spent two and a half years studying the marine ecology and conservation of the endangered, endemic Galápagos Penguin. After completing my PhD, I was a visiting scientist at the University of Bristol, contributing to an international, interdisciplinary project on African Penguins, another banded species now listed as Critically Endangered.

I then took up a postdoctoral position at the University of Cape Town, working on a range of seabird conservation projects and joining the South African National Antarctic Programme. Through this work, the sub-Antarctic islands became a second home. A project on the endangered Northern Rockhopper Penguins eventually led me to Tristan da Cunha, the world’s most remote inhabited island, which has been my ‘home away from home’ since 2012.

Since 2017, I have been based in Cambridge, UK, working as a scientist at the Royal Society for the Protection of Birds (RSPB) where I continued my work on Northern Rockhopper Penguins and now lead the science and monitoring programme for threatened seabird species on Gough Island.

Science alone cannot save threatened species, but it provides a powerful tool to transform data into practical and hopefully long-lasting conservation outcomes.

What does your current role at the RSPB involve?

I work as a Conservation Scientist with the Royal Society for the Protection of Birds (RSPB) in the UK. My research focuses on the UK Overseas Territory of Tristan da Cunha in the central South Atlantic, where I collaborate closely with local partners and the community to support the sustainable protection and management of globally important habitats and species.

Embedded within the Gough Island Restoration Programme, I lead the long-term science and monitoring programme on Gough Island, supporting efforts to restore one of the world’s most important seabird breeding sites.

I am also, unofficially, RSPB’s ‘penguinologist in residence’. With more than two decades of experience in penguin research, I work closely with the Tristan Conservation Department to help protect one of the islands’ most charismatic yet endangered species, the Northern Rockhopper Penguin.

More broadly, my work aims to improve understanding of the processes that shape species distributions, demography, and population dynamics, in order to inform effective conservation strategies. From 2020 to 2022, I also served as RSPB Project Manager for the UK Seabirds Count, coordinating RSPB’s delivery of this national monitoring programme.

Is there a female role model in the conservation sector who has influenced you, and what makes her inspiring to you?

For many women of my generation, figures like Jane Goodall and Dian Fossey have been important role models. They challenged expectations, broke barriers, and pursued their passions with remarkable curiosity, courage and dedication. Their commitment to species and habitat conservation, often in the face of significant obstacles, has been deeply inspiring. Jane Goodall, in particular, has always reminded me that hope is essential, and that believing change is possible is just as important today as it ever was.

Despite progress, gender bias in STEM still exists. I feel fortunate to work in a field that attracts a more balanced mix of genders and to be surrounded by inspiring women and supportive colleagues of all genders. Being part of an organisation with visible female leadership and a genuinely inclusive culture has been crucial in shaping my confidence, career progression, and sense of belonging in STEM.

One woman I especially want to highlight is Juliet Vickery, now CEO of the BTO. When I joined the RSPB, she was Head of the International Section in the Conservation Science Department and later became my line manager. She has been an invaluable mentor and a true inspiration, in both leadership and pursuing a career in conservation science with scientific rigor, care and compassion.

She is a true champion for women in STEM, advocating for equality, supporting career development, and creating opportunities for others to thrive. I am deeply grateful for her guidance, support, and unwavering commitment to fostering an inclusive and empowering environment.

Conservation volunteering with the Dartmoor Preservation Association

NHBS colleague Dan took a refreshing break from the office to volunteer with the Dartmoor Preservation Association. – Read below to find out what he got up to and what he learned.

Page 357 of Dartmoor 365, a unique compendium of Dartmoor by John Hayward, evokes a tranquil scene of early human settlement amidst the wild moorland that is now High House Waste – a place where remnants of a Bronze Age settlement, including a farmstead and field systems, still endure to this day.

Wedged between two streams, High House Waste’s ecological value is as fascinating as its archaeology.
The northern area consists of dry grass and heathland on granite, while the southern slopes feature wet mires on metamorphosed slate. One can find species such as white beak-sedge, bell heather, bilberry, cotton grass, bog asphodel, and sphagnum mosses. The fauna includes meadow pipits, Dartford warblers, common lizards, field voles, weasels, and various flutter-bys.
You may now better understand why an employee of NHBS would eagerly spend a volunteering day with the Dartmoor Preservation Association (DPA) at such a remarkable site.

This would be my second date with the DPA, an organisation I knew would lead me to a special place.
Led by DPA’s chief executive, Tom Usher, the day’s work party embarked on a grafting session to clear gorse from the ancient remains. High House Waste lies a substantial walk from the nearest parking spot along a farm track. Its remoteness aids preservation from visitor pressure and adds to its sense of moorland wilderness.
Though the gorse may offer some resistance with its prickles, it is a joy to work on the moor in the company of beard-lichen-draped trees and with expansive views stretching across the moor.

Left unchecked, gorse would quickly take over and obscure the site’s historical treasures. Included in our work party was an ecologist, as DPA regularly engages such experts to monitor the species residing on its grounds. DPA owns four sites on Dartmoor, all purposefully purchased to protect them from threats like industrial development or to impose conditions more respectful of the land’s ecological, historical, and cultural values.
Defending the natural beauty and cultural heritage of Dartmoor has been the DPA’s mission since 1883. Their website details a timeline of actions, testifying to their ongoing work in planning vigilance, access support, surveys, land management, and conservation both on DPA land and beyond.

As the day’s work drew to a close, the quiet moorland around High House Waste stood testament to the delicate balance between nature and history. Through the careful stewardship of organisations like the Dartmoor Preservation Association, these ancient sites continue to breathe life into our understanding of the past while safeguarding the moor’s wild beauty for generations to come.

Volunteering here is more than clearing gorse – it’s participation in guardianship, a chance to connect with the land’s stories and to contribute to a living legacy. In the vastness of Dartmoor’s wilderness, one finds not only remnants of Bronze Age lives but also a call to cherish and protect the natural and cultural treasures that define this remarkable landscape.

Author interview with Steven J Falk: A Photographic Guide to Flies of Britain & Ireland

Over recent decades various ‘difficult’ insect groups have gradually been brought within reach of the non-specialist thanks to developments in field guides. Flies, however, have remained something of a final frontier, and it’s easy to see why – with more than 7,000 species in Britain alone, creating an accessible and user-friendly guide to this group is a daunting task.

Now, however, a team of expert field entomologists have stepped up to the challenge and produced A Photographic Guide to Flies of Britain and Ireland – the first guide to ever tackle this amazingly diverse insect order as a whole. With beautiful photography and clean, concise text, this book is set to put flies on par with bees and other more ‘popular’ insect relatives, and bring them their due share of attention in the interests of general naturalists.

Ahead of publication, we had the pleasure of talking to lead author Steven Falk about the book’s development and the rewards of fly-recording.

Firstly, how did the book come about?

The idea for the book initially came from Peter Creed, the Creative Director (and Designer) at NatureBureau, which owns Pisces Publications. He wanted a book resembling A comprehensive guide to Insects of Britain & Ireland by Paul Brock, published by Pisces in 2014 (with a 2019 second edition) but concentrating purely on Diptera. He approached Gail Ashton who was helping to man the Dipterists Forum stand at one of the Amateur Entomology Society autumn fairs to discuss the possibility of doing such as book in conjunction with the Forum. Gail eventually agreed to help write it and asked Rory Dimond to assist. I become involved about one-third of the way through the project when it was clear that the book would need several hundred of my images to make it viable (we needed at least 1,500 accurately identified fly photos for the book), and my role later expanded into that of primary author. The internet has patchy information on Diptera, and what does exist can be misleading or out of context with the British fauna, so you need lots of first-hand experience to avoid creating misleading text. Even taking information from trusted literature can be challenging when it needs it be distilled down to short, snappy species accounts. Gail and Rory helped ensure that the text was not overly technical, though inevitably a book on flies ends up more technically worded and microscope-based than a book on butterflies or dragonflies. But we provide good diagrams and a large Glossary to help readers negotiate this. The proof-reading and creative discussions by the members of the team have been very important, making for a much better publication. It helps that all four of us share a passion for breaking down barriers in entomology and enthusing general naturalists about flies rather than just serving the converted. We were also keen to produce a more visually exciting and enticing book than much of the more technical fly literature and online resources available for flies. But we have still signposted those other resources for readers who want to develop a deeper understanding of flies and take things further by providing a good Bibliography. This covers all the key identification literature relevant to a British or Irish audience, both printed and that which is freely downloadable from the internet.

Let’s talk about flies themselves. What makes them so important, and what can recording flies tell us about the state of the natural world?

There are currently about 7,300 species of fly on the Britain and Ireland list, with the possibility of over 10,000 species being present, as we find dozens of new ones each year and DNA is revealing lots of cryptic species. So, if you are passionate about biodiversity and serious about its conservation, you cannot ignore flies. They are typically the most speciose eukaryotic group at a wildlife site and are also incredibly diverse ecologically. I regularly record over 500 fly species at a good wildlife site, and the Windsor Forest and Great Park list stands at almost 2,000 species. Those massive fly assemblages including predators, parasites, saprophages, herbivores, fungivores, pollinators, and so on. What is more, fly assemblages can be found from the intertidal zones of the coast to the tops of our highest mountains. Having some idea of what all those flies are and what they need in terms of breeding sites and adult feeding, makes you view habitats, sites and landscapes in a very different way to a botanist or general ecologist. You notice and value microhabitats and other features that others miss or under-value, such as sap runs or water-filled rot holes in old trees, different sorts of dung, different sorts of ‘wet’, different sorts of ‘decay’, different sorts of ‘bare ground’ and so on. Flies also make you think much harder about aspects such as habitat combinations and mosaics (bearing in mind that fly larvae and adults often have very different needs), habitat connectivity, habitat condition, site history, microclimate, seasonality and climate change. Dipterists are often pretty good botanists and habitat ecologists, but adding flies and other insects to the equation provides a much bigger ‘vocabulary’ when you are trying to understand and interpret the environment. That was particularly important a few years ago when several professional entomologists including myself were assessing the emerging Biodiversity Net Gain metrics. We were able to articulate some powerful feedback to Defra and Natural England concerning the over-simplistic metrics that were emerging, and the serious impact that might have for protecting invertebrate (as well as general) biodiversity. Flies are also really important in ecosystem services (e.g. crop pollination, pest control, sewage treatment). There is strong evidence that they may be more important than bees for the pollination of certain crops, and for general wildflower pollination in habitats like montane grassland and saltmarsh. The role of flies in ecosystems and food webs is something that comes through strongly in the book.

Faced with such a huge group, how did you go about deciding which species to include?

Being a photo-based book, the choice of what species to include is heavily based on what photos are available. But many fly photos on the internet are inaccurately identified, so we had to make sure that such images were either avoided, or (if we could tell what they actually were), used correctly. So, if a species lacked a decent photograph, it could not be subject of a typical species account, though we have name-checked many species without accompanying images within the Similar Species section at the end of many species accounts. For some smaller, iconic families, such as robber flies, horseflies, soldierflies and bee-flies, every published British and Irish species is included. For hoverflies, it is closer to about two-thirds of the fauna, and for groups like parasite flies and the housefly family, it is about half the fauna. In these instances, we tried to include representatives from most if not all the genera in a family and tried to ensure most of the more distinctive-looking or ecologically interesting species were covered. For some of the more obscure or difficult families, only brief coverage is provided. But all 108 fly families present in Britain and Ireland get some level of coverage in the book, which is quite an achievement.

Can you tell us a bit about the book’s approach – what can readers expect from the species accounts?

The book is arranged taxonomically following the sequence of the 2025 Checklist of Diptera of the British Isles which is hosted (and regularly updated) on the Dipterists Forum website. The individual species accounts mostly have a consistent format. It starts with an indication of the size of a fly, either using wing length or body length, then a basic description of the species, often carefully worded to highlight differences from other similar species. We then describe Habitat, Distribution, Season, and (for parasitic or herbivorous species) Hosts. The species accounts are accompanied by a map and photograph or, indeed, two or more photos for species with strong sexual dimorphism or several colour forms. A section on Similar Species is also used in many cases, namechecking other flies that might be confused with the main subject. These extra species are also sometimes provided with a map and photo. It means that about 1,300 species of fly get namechecked by the book (about 1,100 of these with standard species accounts). But it often came down to what space was available on each page spread as to what got covered. Suffice to say we used a flexible and opportunistic approach to ensure we made the most of each double-page spread.

The guide is beautifully laid out and packed with outstanding imagery. Was it a challenge gathering photos for all the flies you wanted to feature?

About 40% of the photos come from me and were already featured on my Flickr site. That made image selection for some families much easier and meant that Peter Creed could quickly download any of my images, and if I disagreed with an image choice, I could quickly send him hyperlinks to the image I preferred. Peter, who is also a keen insect photographer (and always thinking of the next potential Pisces book), provided about 20% of the images. We also turned to reliable British insect photographers such as Paul Brock, Simon Knott, Kevin McGee and Ian Andrews, and approached other photographers if we spotted images of further species on the internet (or better images of a species than we had to hand). The result is that we’ve ended up with over 1,500 images of over 1,100 species and have used images from 186 photographers. Suffice to say, we are immensely grateful to everyone who provided images.

For the general naturalist who has yet to become a fly convert, what can you say about the rewards of studying these insects?

Flies have huge intrinsic interest in terms of interesting appearances (including mimicry, loss of wings, bizarre wing markings and strange body modifications), interesting lifecycles, interesting behaviours, and their importance in ecosystem services. They are great fun to photograph (with cameras like the Olympus TG series making it easier than ever), and it is relatively easy to identify some from photos, either using this book, or by posting images on the various Facebook groups that cover flies (where others can provide feedback on what they think your photo is). Flies also provide an incredibly powerful framework or lens for interpreting and understanding habitats and landscapes better, as explained above. I think that aspect (using flies to view understand the environment more critically) is truly exciting and very rewarding.

What tips would you give for someone looking to take a deeper interest in flies and find a greater range of species?

Buying a stereo zoom microscope makes a big difference as it allows you to identify flies with much greater confidence and appreciate the beauty in the details of their morphology. While we are aware that many users of the book will not want to go down the road of collecting and killing flies for the purpose of identifying them critically, that is the approach that is generally needed to develop long and accurate species lists for a site. There is a limit to what can be achieved through photography. But going down the collecting route also means buying an insect net, tubes and pooters, insect pins and storage boxes for pinned specimens, plus obtaining some of the key literature listed in the book’s extensive bibliography, such as British Hoverflies (Stubbs & Falk 2002), published by the British Entomological and Natural History Society. I would also strongly recommend joining the Dipterists Forum. This is the national society for the study of flies and is very friendly and well-organised. It publishes a regular newsletter (Bulletin of the Dipterists Forum) and journal (Dipterists Digest) and organises regular indoor and outdoor events. It has a great website that can be used by non-members but has extra resources for logged-in members. The Forum acts as an umbrella for almost 30 family recording schemes or study groups, some of which have their own Facebook groups or satellite websites. Nowhere outside of Britain and Ireland comes to close to matching that offer.

Finally, what do you hope the book will do for interest in flies and fly recording?

We are hoping it has a major impact, not only by making general naturalists more aware of, and sympathetic towards flies but also by encouraging more naturalists to take up formal recording of flies as outlined in the previous response. Many parts of Britain have few (if any) resident fly recorders, and it would be especially good to promote recording in those areas, even if it is just the recording of easier groups such as hoverflies. Climate change is having a profound impact on insect life, and the more data we get, the more we understand that impact and formulate strategies to counter it through improved habitat management and other land use decisions. We hope that this book will support constructive dialogue – ecologists, farmers, planners all a little bit more familiar with flies, able to be enthusiastic about them and their conservation.

The Big Garden Birdwatch: NHBS Staff Results 2026

The RSPB’s Big Garden Birdwatch took place between Friday 23rd and Sunday 25th January 2026. This is an annual event is one of the largest citizen science wildlife surveys in the UK and helps us gain an understanding of how our garden bird populations are changing in abundance and distribution over time.

In last year’s event, over 590,000 people across the UK took part, counting 9.1 million birds! While House Sparrows took the top spot, counts of this species are down by 64% compared to the first Birdwatch in 1979, mirroring a wider and worrying decline in our bird populations: we’ve lost 38 million birds from UK skies in just the last 60 years. With birds facing so many challenges, it’s more important than ever to get involved in the Birdwatch and continue monitoring their fortunes.

Although the Big Garden Birdwatch has finished, there is still time to submit your results on the RSPB website. Even if you didn’t see anything, it still counts!

Acoustics for surveying dormice and other small mammals

This is an updated version of a blog first published in 2020.

As static bat detectors continue to be more widely used and the technology improves, there are now many thousands of hours’ worth of nocturnal recordings captured each year from a vast spread of locations. This level of coverage has not only improved our ability to monitor bat populations, but also offers the potential to gather information on other animals that communicate at the same ultrasonic frequencies as bats. The calls of bush-crickets, for example, are commonly picked up as ‘by-catch’ during bat surveys, which has allowed the development of software that automatically recognises any cricket calls in a recording and assigns them to individual species.

Back in December 2020,?British Wildlife published an article by Stuart Newson, Neil Middleton and Huma Pearce exploring the potential – relatively untapped at that time – of acoustics for the survey of small terrestrial mammals (rats, mice, voles, dormice and shrews). Small mammals use their calls for a variety of purposes, including courtship, aggressive encounters with rivals and communication between parents and offspring. To the human ear, the high-pitched squeaks of different species sound much alike, but closer examination reveals them to be highly complex, extending beyond the range of our hearing into the ultrasonic and showing great variation in structure.

Mammal terrariums used for holding individuals overnight in the recording ‘studio’.

To answer the question of whether it’s possible to distinguish the calls of different species, the authors went through the time-consuming task of building a call library by taking recordings of all Britain’ native (and some non-native) small mammals. Call-analysis software was then used to examine the recordings and look for consistent differences between species, with some fascinating results – the calls of shrews, for example, can be readily separated from those of rodents by their warbling/twittering quality, while the house mouse typically calls at a higher frequency than any other species. Remarkably, it appears overall that the vocalisations of most species have their own diagnostic features, and that, with care, it should be possible to identify a high proportion of calls to species level. .

Recorded calls of (a) Brown & (b) Black Rats

Small mammals are unobtrusive and hard to observe, which means that even the more familiar species, such as the Brown Rat, are severely under-recorded. Given how critically important small mammals are within the food chain, this lack of knowledge is a problem – one that is gaining increasing attention, including through the creation of a Small Mammal Research Working Group by the Mammal Society.

In the mission to improve understanding of small mammal populations, the ability to detect and identify species by their calls therefore offers great potential as a survey tool. Analysis of calls collected by static detectors – whether specifically set to target small mammals or deployed as part of a bat survey – is already providing a rich source of data and helping to complement traditional methods, such as the use of Longworth traps or footprint tunnels.

Furthermore, this method also shows promise for monitoring some of our most threatened small-mammal species. In Winter 2023, an article in Conservation Land Management described a novel trial in which static-acoustic detectors were used to monitor the protected Hazel Dormouse (you can read the article in full here), with positive results. Two years on, we spoke to Stuart Newson, coauthor of both articles and the pioneering Sound Identification of Terrestrial Mammals of Britain & Ireland, about more recent developments in this exciting field of ecological survey.

Stuart writes, “Since the publication of our article in Conservation Land Management, our understanding of Hazel Dormouse acoustic identification has continued to advance, alongside major improvements in the BTO Acoustic Pipeline’s ‘bat’ classifiers, for automatically detecting and identifying the calls of this species.

As with bats, potential identifications still require verification by visually inspecting spectrograms and listening to recordings. However, this process can now be carried out relatively routinely alongside bat sound identification.

As a proof of concept, Hazel Dormouse recordings from Great Britain (2021–2024) that were shared by users of the BTO Acoustic Pipeline were manually verified. This work has produced what we believe may be the first national-scale map of a small terrestrial mammal generated using acoustic data – and it just represents the beginning.

Over the next six months, and through a collaboration with APHA and funded by Defra, I, with the BTO will manually verify small terrestrial mammal detections (from .wav files) that have been identified as ‘by-catch’ within bat acoustic data submitted and shared by users of the BTO Acoustic Pipeline across the UK and Ireland.

The total number of verified identifications for Great Britain and Ireland is still to be determined. However, between 2021 and 2025, the wider (predominantly European) dataset already includes an incredible 1,177,597 small mammal identifications.

This planned project offers a unique opportunity to demonstrate the power of acoustic monitoring for identifying small terrestrial mammals at an unprecedented spatial scale. It will also create a large, novel dataset that has the potential to transform our understanding of these species – including insights into their seasonal and nightly vocal activity patterns across the UK and Ireland.”

The birth of the Earth Rover Programme

A groundbreaking new soil-health measuring technique could be crucial in helping to avert famine and drought. Most soil properties are undetectable from the surface, meaning that farmers currently rely on broad interventions such as fertilising and tilling the whole field, which is harmful to soil health and wildlife. The newly convened ‘Earth Rover Programme’, will use seismology (measuring down to the Earth’s crust, usually to assess potential for earthquakes) to assess the properties of soil in detail for the first time. The non-profit programme was set up with the support of author George Monbiot who called for an ‘advanced science of soil’ in his 2023 book Regenesis. A greater understanding of localised soil properties could be instrumental in maintaining global food security and creating a greener future for agricultural production.

Winter blooming in the UK

The annual New Year Plant Hunt organised by the Botanical Society of Britain and Ireland (BSBI) has taken place. Early results show common wildflowers such as Daisies and Dandelions among the hundreds of native species that have bloomed unexpectedly. The annual plant hunt has revealed and seen an increase of 2.5 species in bloom for every 1C temperature rise. Kevin Walker of the BSBI has described the early blooms as a ‘visible signal’ of climate change and a ‘very clear link between rising temperatures and impacts on our plant species’.

The BSBI study focused exclusively focused on Britain and Irelands flora, however, there is evidence of warming effecting spring phenology across Europe and beyond.

UNEP Global Environment Outlook Report

The Global Environment Outlook (GEO) report, the United Nation’s Environment Programme (UNEP) flagship report which monitors global environmental change, has been released. The 2025 report emphasised several ‘critical truths’ including the fact that environmental crises are political and social emergencies. Robert Watson, co-chair of the assessment says that the climate crisis, destruction of nature and pollution are ‘undermining economy, food security, water security, human health and national security’. The report is usually followed by an agreement summary approved by the world’s countries, however, objections from Saudi Arabia, Iran, Russia, Turkey and Argentina regarding the proposed inclusion of references to fossil fuels, plastics, reduced meat in diets and other issues meant that no agreement was reached. The report proposes measures such as universal basic income, taxes on meat and subsidies for healthy, plant-based foods alongside the removal or repurposing of environmentally harmful subsidies to fossil fuels, food and mining.
