Author interview with Roy Dennis: Restoring the Wild

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Amphibian and Reptile Conservation Trust: Q&A with Dr Tony Gent

The Amphibian and Reptile Conservation (ARC) Trust is a charity dedicated to conserving amphibians and reptiles and saving the disappearing habitats on which they depend.

Dr Tony Gent, CEO of the ARC Trust, recently took the time to talk to us about the challenges faced by amphibians and reptiles in the UK, some of the charity’s success stories, and ways in which you can get involved with amphibian and reptile conservation.

Firstly, could you give us a brief introduction to Amphibian and Reptile Conservation and the work that you do?

Amphibian and Reptile Conservation (ARC) is a national conservation charity dedicated, as its name suggests, to conserving frogs, toads and newts, snakes and lizards. ARC manages a network of over 80 nature reserves in England and Wales that cover some 2,000 hectares. These include a significant suite of lowland heathland areas that are home to all six native reptile species. The trust is also custodian for nationally important habitats for natterjack toads and pool frogs, plus sites established specifically to support populations of great crested newts.

ARC leads on recovery programmes, especially for more threatened species, including managing reintroduction and captive breeding programmes, direct engagement through site management and running national monitoring schemes. We actively engage with advocacy in the UK and further afield, to ensure that amphibians and reptiles are considered via legislation, policy, and funding streams. We also support and undertake research and run education and training programmes to promote amphibian and reptile conservation. Though UK based, we also work with partner organisations across Europe and in the UK’s Overseas Territories.

Our team achieves this through a network of volunteers, partner organisations, Governmental agencies and engaging with the wider public.

As for most groups of animals in the current climate, the factors affecting their populations are obviously complex. However, what do you consider to be the greatest challenge faced by amphibians and reptiles in the UK?

A number of factors are impacting on our reptile and amphibian populations including disease, climate change, pollution, drought and wildfires. However I consider the biggest challenge is ensuring that there is enough suitable habitat available for these species to maintain their populations and distribution across the country, given the vast pressures for alternative land uses.

Of our seven species of amphibian, comprising of three newt, two frog and two toad species, some such as the common frog are widespread, while others such as the natterjack toad are found in a restricted number of habitats and endangered. Similarly, the three species of lizard and three species of snake that make up our reptile fauna include widespread species, such as the slow worm, and other species such as the smooth snake and sand lizard that have much more restricted ranges. All, however, need certain habitat features to survive; reptiles in particular need generally open habitats with a good ground cover, while amphibians need ponds for breeding.

Smooth Snake – by Chris Dresh

The loss and degradation of the habitats on which these rare amphibians and reptiles depend has been a major factor contributing to their decline. Pond numbers in England and Wales decreased dramatically from an estimated 800,000 in the late 19th century to around 200,000 in the 1980s; this in turn has impacted on amphibian populations. Heathland, the only habitat occupied by all six of our native reptile species, has declined by over 85% since the late 18th century. The heaths that remain are highly fragmented, meaning that some patches are too small to sustain characteristic native reptile species.

As well as ensuring that areas are not lost to competing land uses, such as development or intensive agriculture, it is important that these areas sustain the features within them that allow amphibians and reptiles to survive. Having comparatively low mobility, we also need to ensure there are linkages between these areas to prevent populations becoming isolated and to allow for recolonisation if for any reason they become locally extirpated.

Our work securing areas as protected nature reserves can help address this, but we need to see action over a much wider area. ARC both undertakes and provides advice on habitat management on behalf of landowners, who are often steered by government directives. We therefore also lobby for more robust land use policies and funding mechanisms that encourage sympathetic land management. Agri-environment schemes, for example, protect land from the impacts of development, or at least fully mitigate any unavoidable damage that will occur. Underpinning this is the need for a greater awareness and regard towards the conservation of these animals, so that they are considered positively in decision making.

Within the UK, reptiles and amphibians are notoriously elusive – do you think that this affects the extent to which people are aware of them and the conservation issues that they are facing?

The elusive nature of these species makes it difficult for people to see them and therefore often misunderstand them.

In appearance they are neither feathered nor furry and lack the inherent universal appeal of some other animals. This has contributed to their negative profile in tradition and folklore which are often associated with evil, witchcraft and common ailments such as warts. Indeed, even Carolus Linnaeus, the great biologist and ‘father of modern taxonomy’, described reptiles and amphibians in his book The System of Nature as ‘These foul and loathsome animals are abhorrent because of their cold body, pale colour, cartilaginous skeleton, filthy skin, fierce aspect, calculating eye, offensive smell, harsh voice, squalid habitation, and terrible venom.’

This matters because people’s appreciation and negative perceptions of amphibians and reptiles are echoed in the low importance placed on their conservation, leading to their needs being often just not considered. This can range from direct persecution to simply over-looking their habitat needs, for example in tree planting programmes.

It is hard to appreciate something you cannot see; indeed many people are not aware that we even have reptiles in UK. However, once appreciated they then become important to preserve. That’s why at ARC we place great importance in getting people to see and to learn about the amphibians and reptiles in their area, and to learn how and when they can be seen.

The sight of frogspawn in the garden pond followed by tadpoles and the unmistakable sound of croaking frogs can offer a close-up experience of wildlife and, for some people, this has been the start of a lifelong interest in nature. We are also seeing an increasing fascination with our native ‘dragons’ and recognition of their cultural significance.

This past year has been unbelievably hard for charities. How has 2020 (and 2021 so far) differed for the ARC Trust and how have you dealt with the difficulties that Covid has created?

Covid shut the door on many of our activities, and especially face to face meetings with people including many educational training events and group activities. This has had a number of different impacts, including the amount of habitat managed, opportunities for us to show people reptiles and amphibians and our volunteer engagement. However we maintained work across all of the different areas of our activity – it just meant we had to do these in different ways and have gained from doing so.

As we saw home working and ‘Zoom meetings’ become the norm we were in a position to move many of our education and training events online swiftly. Over the year of restrictions we have developed free ‘bite sized training courses’ and have made some of our sites accessible virtually through virtual reserve walks, drone tours, Q and A panel sessions, quizzes, activities and classroom lessons for children. As lockdown continued, people became more aware of their immediate environments and we offered an opportunity for the public to undertake a home-based survey through our online Garden Dragon Watch survey in addition to our reserves remaining open throughout.

Our two major annual events, the scientific meeting that we co-host with the British Herpetological Society and the Herpetofauna Workers Meeting run jointly with ARG-UK, went online. We explored different platforms for these meetings and, while we couldn’t meet face to face, these meetings attracted larger audiences than we could have hosted through physical meetings, reduced costs and gave a voice to people who had not previously joined in before. This not only significantly reduced the carbon footprint of these events but actively engaged a wider range of delegates, networks and researchers. We will be looking at how we can integrate some of these positive outcomes into future outreach.

What would you consider to be your greatest success story so far?

Ultimately we aim to improve the conservation status of all 13 native species of amphibians and reptiles in the UK. Securing 80 sites into active conservation management, 25 of which we own, is something that we would not have imagined possible when the foundations for forming the charity were being laid in the late 1980s. In terms of conservation impact, our translocation work has truly brought species back from (and in one case beyond) the brink of extinction in Britain.

Sand lizards suffered significant declines across their range during the mid to late 20th Century, disappearing from Wales, seeing a huge reduction in the Merseyside populations and loss from huge swathes of Surrey, Hampshire and Kent. We have led conservation efforts for this species in Britain and in 2019 we released our 10,000th sand lizard as part of our long-term reintroduction programme which has restored sand lizards to 70 sites, restoring much of their former range. Similarly, the range of the natterjack toad dwindled over a similar time period and down to a single surviving heathland population south of the River Thames. We have been involved in reintroducing natterjack toads to 17 sites across the UK.

Perhaps our greatest species success story is the pool frog which was formerly considered to be non-native and went extinct from the UK in the 1990s. We worked in partnership to assemble evidence to indicate that they were in fact native and, through our reintroduction programme, we sourced pool frogs from Scandinavia and successfully reintroduced them to Norfolk, bringing the species back from extinction in the UK. Our latest Green Recovery Challenge government funded project will explore how we can restore the species range in East Anglia, by trailing outdoor enclosures.

Our greatest success overall is the combination of seeing the status of wildlife improve and the benefits that come to people because of what we do. In the course of working towards our primary mission of conserving amphibians and reptiles, we benefit many other species that share their habitats, such as birds, butterflies and dragonflies. We also provide benefits directly to our volunteers and the public who enjoy our reserves that tell us they benefit in terms of their physical and mental health, social lives, enjoyment, education and career development.

How can people get involved with amphibian and reptile conservation, particularly if they are inexperienced in terms of identification and/or field survey?

Reptiles and amphibians occur throughout the country, but the species that you may encounter will vary in different locations and habitats. There are a variety of ways you can get involved through ARC, and whatever your background, we welcome your support.

If you live close to one of our nature reserves or local projects you might like to join a habitat activity day. We run programmes of habitat management designed for teams of volunteers mainly through the winter months – It’s a great way to keep fit, make friends and get a personal insight into looking after your local nature reserve. ARC also offers opportunities to learn more about amphibians and reptiles through training, including online, field and class-based courses and events run in partnership with the Field Studies Council. We are keen to have more people joining in with our national programme of species and habitat surveys, which has various options for people with different levels of knowledge and available time. There is also an opportunity to take part in our Garden Dragon Watch (recording amphibians and reptiles in your garden), or if you have more time sign up to monitor species at a location near you, though the spring and summer months. The information volunteer surveyors supply is valuable in helping ARC to keep track of where amphibians and reptiles are found and how populations are faring.

ARC also runs a members’ scheme for people who wish to support the work we do, stay up to date with the ecology and conservation of amphibians and reptiles, gain discounts to events and conferences and claim a welcome pack containing an array of species identification resources.

Author Interview with Dave Goulson: Gardening for Bumblebees

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Author Interview with Andrew Painting: Regeneration

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Conservation Land Management: Spring 2021

The magazine that went on to become Conservation Land Management (CLM) first went to print in the spring of 1993. At this time it was named enact, and was published by English Nature (the predecessor of Natural England). The aim then was to promote land management for nature conservation and provide easy-to-understand advice on useful techniques – an objective that CLM still stands by today, but now covering a much wider variety of conservation issues. Here, Assistant Editor Catherine Mitson highlights the key articles of the latest Spring 2021 issue.

The UK’s departure from the EU offers a number of opportunities for the environment, and in particular for the future of farming in the UK. And so, agricultural policy is undergoing a reform and a new payment scheme, the Environmental Land Management scheme (ELM), has been introduced to England.

ELM will pay farmers based on the public goods they provide, such as habitat restoration or flood management, as a means of contributing to the government’s 25 Year Environment Plan. But is ELM up to the task of delivering its aim? In this issue Alice Groom, RSPB’s senior policy officer, provides an up to date overview of what we know about ELM so far, the proposed timeline of the seven-year agricultural transition period, and, importantly, highlights the pitfalls and challenges that need to be addressed in order for ELM to be a success.

Staying within the theme of farming, exciting new approaches are being trialled in the The Great Fen, which stretches between Huntingdon and Peterborough, and is undergoing landscape-wide restoration to improve the sustainability of the fens for both people and wildlife. Within this vision, the Great Fen team are in the midst of the three-year Water Works project that is focused on a ‘wet farming’ approach. Wet farming is a type of agriculture on wetter soils, a much more suited approach for the natural conditions of the fens; this will help to protect peat, lock in carbon, support wildlife and provide local farmers with new economic opportunities.

Novel crops, such as gypsywort, bulrush, sphagnum moss and watercress, chosen for their potential uses for food, flavourings and medicine, are currently being trailed in specially prepared planting beds. Data is simultaneously being collected to measure the rate of carbon capture and loss in these trial plots – it is hoped that not only will carbon loss be reduced within the Great Fen, but also that these changes in fenland agriculture will help sequester carbon too.

Ribble Rivers Trust (RRT) also seeks to improve the condition of existing habitats, and uses an evidence-based approach to target land management where it will have the biggest benefits for wildlife, people, and the environment. Focused in the Ribble catchment in north-west England, Ellie Brown, GIS data and evidence officer at RRT, demonstrates how the use of mapping and data analysis has helped the charity to identify key areas for conservation projects.

One example of this has been along Bashall Brook. Using solar radiation maps RRT identified a particular stretch of the watercourse that was at risk of overheating. The main reason behind the increase in water temperature in this area was a lack of surrounding vegetation providing enough shade, and so it was decided to create a woodland running along either side of the bank. RRT is conscious to only ever plant trees where it is appropriate, and the resulting vegetation has helped to create much-needed shade along the brook.

In some circumstances all it takes is just a handful of people in a local community with a shared passion to come together to make a difference. In 1970 the Bristol section of the M5 motorway was opened and, during this work, a particular stretch of St George’s Hill had the topsoil removed from the roadside verge. Giles Morris, a conservation volunteer with St. George’s Flower Bank, describes how a dedicated team of volunteers from the local villages worked together to clear the encroaching scrub on this verge, and how this led to the establishment of a species-rich grassland. This on-going management project has been a huge success, and the site has since been declared a Local Nature Reserve.

Conservation success stories, such as that of St George’s Flower Bank, make for an inspirational read. And staying on a positive note, beavers are certainly grabbing the attention of many in recent years and have been reintroduced to a number of different sites across the UK. For our Introducing feature it was a delight to have Eva Bishop discuss how the Beaver Trust came to be, what it is trying to achieve, and the exciting projects it has been involved in.

In every issue you can expect to see Briefing and On the ground, but other features that regularly appear include Viewpoint, a similar length to our main articles, but here authors can voice their own views on various conservation issues; Introducing, a feature focused on organisations involved in conservation, and here they can discuss their aim and describe specific conservation projects they are involved in; and Review, which can include letters from readers or updates from our authors.

CLM is published four times a year in March, June, September and December, and is available by subscription only, delivered straight to your door. Subscriptions start from £22 per year. Previous back issues are also available to purchase individually (subject to availability).

If you are involved in a conservation project and think your experiences could be useful to other practitioners, we would love to hear from you. If you are interested in writing for CLM feel free to contact us – we will be happy to discuss your ideas with you.

Phenology – the study of seasonal timing

Wild Daffodil by Charlie Jackson via Flickr

Although humans were undoubtedly more attuned to seasonal cycles in the pre-industrial era, the changing seasons and associated renewal and decay still exercise a powerful influence over us. Anyone who has ever smiled upon hearing the first swifts of the year screaming across the sky, or felt their spirits lift at the appearance of the first wild daffodils, is observing phenological events.

Phenology is the study of seasonal natural phenomena such as the budburst of trees, arrival and departure of summer migrants, first egg layings, emergence of hibernating animals and appearance of plankton blooms. Phenological records have greatly enhanced our understanding of ecological interactions, and have proven invaluable in demonstrating the effects of climate change on terrestrial and marine ecosystems. Our fascination with the rhythm of seasonal cycles persists even in our modernised world and many phenological records have been, and continue to be, provided by the public.

History of Phenology and Climate Change

Although strictly speaking the word ‘phenology’ refers to the study of seasonal events, its use has broadened to refer to the seasonal events themselves, i.e. when an event occurs during the year. Seasonal events such as budburst have been consistently recorded in the UK by generations of dedicated relatives of Robert Marsham (from 1736 until 1958), by English naturalists Gilbert White and William Markwick (from 1768 until 1793), by a network of 600 ‘Phenological Reports’ observers across the UK (from 1891 until 1948) and from 1949 by Jean Combes in Surrey.

Modern techniques to monitor phenology include vegetation indices and remote sensing from satellites and aerial surveys, rather than individual observations. These data have provided an essential record of key seasonal markers that have clearly shown a shift in the phenology of many species due to warming temperatures. The latest research indicates that oak budburst is now more than 11 days earlier than in the 19th Century. This has massive implications for the species that rely on oak trees and their associated invertebrate communities for food and shelter. Much of the research demonstrates that species such as Great Tits and Pied Flycatchers do not have the flexibility in their seasonal timing of egg laying and migrating to match the shift in tree and invertebrate emergence.

Phenological Interactions

In many ecosystems a seasonal abundance of a resource can drive natural selection, influencing which individuals of a species struggle or thrive. Individuals that can time their seasonal cycle to coincide with an abundance of food are usually more successful in terms of breeding or survival. For example, there is a very well researched phenological interaction between Great Tit nestling feeding and caterpillar abundance. The birds judge when to begin their breeding attempt so that the peak energetic demands of their chicks (around 12 days after hatching) matches a very brief peak in caterpillar numbers. The females that can do this more accurately and be more flexible to variation in timing between years (phenotypic plasticity), are more likely to have offspring that survive to breed themselves. There is an interaction between the caterpillars and the oak leaves they feed on too; the caterpillars need to emerge when the oak leaves are small, before the tannins in the leaves build up enough to stop them being eaten.

There are also less competitive and more mutually beneficial phenological interactions, such as between migrating hummingbirds and the flower species that rely on them for pollination, and between emerging insect pollinators and spring flowers. The intricacy and importance of phenological interactions between species has raised great concerns about the ability of entire ecosystems to adapt to warming temperatures. A phenological mismatch can occur when the timing between the interacting species or individuals does not change to the same degree.

Phenological Recording and Observing – How to Get Involved

The recording of phenological events has always relied on consistent, repeated observations by amateur naturalists and members of the public. By collating annual records of key phenological markers, extensive databases of seasonal records have been built up. Initiatives such as ‘Nature’s Calendar’ run by The Woodland Trust, gather data from thousands of volunteers and contribute long-term data to research projects. You can choose which species and events you record and know that you are contributing to an important project because these data are invaluable to researchers for tracking the effects of climate change on our seasonal ecology.

Nature’s Calendar also has a downloadable Phenological Calendar so that you can see where your records fit into national averages. This also gives you a fantastic insight into which seasonal events to look out for each year.

6th International Berlin Bat Conference – Interview with Christian Voigt

The 6th International Berlin Bat Meeting is due to be held online from 22nd–24th March 2021 and will consist of a series of live lectures delivered via video link. To make it possible for people to attend from around the world, the lectures will also be available to watch on demand. At NHBS, we’ve always loved being involved with the Berlin Bat Meeting and hope that soon we can attend again in person!

In the build up to this exciting event, organiser Dr. Christian Voigt kindly took the time to answer some questions about this year’s meeting. Dr Voigt is Head of the Department of Evolutionary Ecology at Leibniz Institute for Zoo and Wildlife Research, Lecturer at the Freie Universität Berlin and Member of the Berlin-Brandenburg Centre for Stable Isotope Ecology.

The theme of this year’s International Berlin Bat Meeting is ‘The Human Perspective on Bats’. Can you tell us why you decided to choose this particular theme?

We decided on this topic because we became aware of the necessity to address bat conservation from a more holistic approach. Conservationists often have the saying ‘wildlife management is the management of humans’ and this is very much true. We need to better understand the emotions and attitudes of humans towards wildlife in general and bats in particular, in order to protect wildlife and bats respectively. Ultimately, this will make conservation more efficient. The Covid-19 pandemic told us that we were right because many aspects of bat conservation have turned more difficult when some people changed their attitude towards bats. It is important to remember that bat conservation does not only mean dealing with the protection of bat populations but also with their ecosystem function. In many cases, bats are very helpful for humans, e.g. by consuming large numbers of pest insects or because they pollinate flowers or disperse seeds. Becoming aware of these ecosystem services might change people’s minds about why they should care for bats. Lastly, zoonotic diseases such as Covid-19 emerge because the way we treat wildlife is wrong. Poaching, wet markets, our whole interaction with wildlife has to be reconsidered and we will be talking about this during the International Berlin Bat Meeting. The topic of the upcoming IBBM `’The human perspective on bats’ is more relevant and timely than ever.

What do you think are the key conservation challenges currently faced by bats?

The major challenge is now to re-establish a good reputation for bats. Bats are key players in ecosystems, they are important indicator species, and many species are rare or even threatened. We need to care for them.

How do you hope that this meeting will contribute to the work required to address these challenges?

Our hope is that we come up with ideas about how to approach bat conservation and human-bat interactions from a different angle. This conference will bring together people from various geographic backgrounds and from a variety of disciplines. It is this exchange of ideas and perspective that make the IBBM quite unique among bat conferences.

Meetings such as these provide an unrivalled chance for attendees to share ideas and network. Do you know of any key projects or collaborations that have arisen from previous International Berlin Bat Meetings?

The networking that happens during these meetings is huge. The very first IBBM on bat migration brought this topic to the attention of many people and lots of papers have been published since then. Specifically, our meeting on bat diseases, right when white-nose syndrome hit North American bats, stimulated a lot of excellent research on both continents. I remember that we sat together during the IBBM and discussed what should be done and what to expect.

Organising an online meeting must be very different in comparison to organising an ‘in person’ event. How have you found the process? And have you noticed that there are benefits to this format, as well as challenges?

Organizing an online meeting is overall not difficult, it was the postponing of the conference, not knowing when to reschedule it and not knowing how people would respond to an online instead of a presence conference that caused us sleepless nights. Now that we have already organized a few online events, the task seems doable. Overall, the benefits are that people from many more places on our globe can participate in this event without having to pay the travel costs. The challenge for these kinds of conferences is to maintain a format in which people feel encouraged to discuss and to interact. This can be better achieved when you meet in person, e.g. during coffee breaks. It is my hope that we have a very lively discussion and a very stimulating event.

Butterfly Conservation Moth Recorders’ Meeting 2021

On Saturday 30th January I attended the first online Moth Recorders’ Meeting of 2021, organised by Butterfly Conservation and chaired by Dr. Richard Fox. Although it was still a couple of months from the time when people would be putting their traps out in earnest for the spring/summer influx of species on the wing, there was a poignant and reflective look back on the strange year that had just been. It was also noted how, through national lockdowns and social distancing measures brought on by the global pandemic in 2020, there had been an indisputable increase in appreciation for the importance of moths and butterflies. It was mentioned that, at the time of the meeting, there had been 14 million impressions across social media platforms using the hashtag #mothsmatter and an insatiable appetite for the Butterfly Conservation hawk-moth identification sheets and for moth traps!

The impact of lockdown on moth recording

The first talk of the morning from Dr. Zoe Randle discussed the connection to wildlife that was kindling in our homes and gardens through 2020, and reported that there was, in the last year, a 62% increase in records submitted to Devon Moth Group, and a 72% increase in recorders! This speaks volumes about a growing awareness and appreciation for moths and provides vital data on the bigger picture of how our native species are faring. There is also evidence to suggest that 2020 was a boom year for the Jersey Tiger moth, with abundant national sightings indicating that the species could be expanding its range further north.

Inevitably, this influx of records requires consolidation by county moth recorders on local levels in order to feed them into the national dataset, and it was these hard working volunteers who were the focus of Zoe’s talk. Specifically she discussed the best ways to support them in their rolls and investigated the demographics of county moth recorders alongside details on the submission status at the time.

The pandemic has resulted in a huge increase in submitted records and email correspondence

This need to streamline the information in support of county moth recorders was echoed and advanced by Dr. Katie Cruickshanks who was next to speak.

Katie spoke about the benefits of this widening pool of public participation suggesting that, not only does it expand our understanding of national biodiversity, but it also connects us meaningfully with wildlife and has positive effects on our own personal wellbeing. Public perception of moths and butterflies is improving through events like Butterfly Conservation’s Big Butterfly Count, which encourages people to log the species they see in their local patch for a set period of time using a dedicated app. The wealth of sightings that come through apps like this and iRecord – alongside information gathered from social media and anecdotal sources – has meant that the recording process is a vast and time consuming activity for volunteers. Katie spoke on how this process currently works and speculated on how it might be streamlined moving forwards.

Data from citizen science projects and moth recording is vital for making conservation decisions, compiling atlases and for directing policy.

As a follow up to the publication of the Atlas of Britain & Ireland’s Larger Moths at the end of 2019, Dr. Richard Fox spoke next on the state of Britain’s larger moths.

The compilation of data for the new State of Britain’s Larger Moths 2021 report was an ambitious project and took into account 50 years worth of accumulated information, providing a unique understanding of moth population trends. To date, it represents the longest-running standardised monitoring of insect populations anywhere in the world. The study divides data to create a more accurate picture of the abundance and distribution of larger moths across the country, and takes into account northern and southern records separately to build a stronger idea of where increases and declines in species numbers are occurring. Overall abundance of larger moths caught in traps over the 50 year survey period points to a concerning 33% decline across the country (with a southern decline of 39% and a northern decline of 22%). There is, however, evidence that moth species in the UK have increased their distribution by 9% over a 47 year period (1970-2016).

Changes in moth abundance over a period of 47 years

Dr. Fox also talked through the understanding we now have of distribution indicators for different habitats including woodland, grassland, moorland and heathland. These indicators suggest that “loss and deterioration of wildlife-rich habitats is probably still the main cause of population declines”.

Distribution indicators for several habitat types

There are, however, many nationwide projects working to correct for this and enrich habitats once again; such as the Highways England roadside verge scheme managed by Butterfly Conservation’s Dr. Phil Sterling, which is working to create improved grassland habitat corridors along roadsides.

Next came a passionate report on moth trapping through lockdown from Luke Phillips (Dorset RSPB). In this personal account of how national restrictions pushed him to connect more keenly with wildlife locally, Luke described some of the star species that visited his patch throughout the long spring and summer season of 2020, including a scarce Alder Kitten (Furcula bicuspis) and an unusual Birch Mocha variant (Cyclophora albipunctata).

Luke has been involved in a number of public engagement activities that encourage individuals and families to embrace the wildlife in their own spaces, including nationwide moth trap reveals and The Big September Sleepout, which sees hundreds of families across the country meeting to camp in wild places and witness the wildlife around them. In the last year these activities have still occurred, but with participants camping in their own gardens and spaces (in accordance with social distancing measures) and then convening virtually to discuss their findings. The uptake on these activities has been really encouraging and, besides the obvious benefits to wellbeing of connecting people and wildlife in these ways, these moth mornings and camp-outs also produce lots more data for Butterfly Conservation!

The final speaker of the day was Dr. David Wagner, a systematist and lepidopterist from the University of Connecticut, who spoke about Insect Decline in the Anthropocene and How Moths are Faring. David discussed our current understanding of anthropogenic impacts on climate through habitat destruction and the intensification of agricultural practices around the world, and how their knock-on effects impact on parts of the tropics that are still feeling little to no direct harm from these practices. As a result of spreading drought conditions through the world’s grasslands and cloud bank diminishment in the tropics it is clear that insect abundance is in decline (although some species are faring better than others, and even increasing in numbers).

Cloud bank diminishment in the tropics over a period of 30 years

David pointed out that the most concerning thing is situations where there are declines in common/abundant species in parts of the world where there is little to no anthropogenic impact. This indicates a systemic problem that we can’t yet see. But in the unique case of the United Kingdom, where we have a vast archive of data collection and large levels of public involvement in monitoring, we can see more clearly the impacts of emerging anthropogenic factors, and this can inform our understanding to a certain degree. This depth of research has still not been realised in most parts of the world which means our global view of how insect populations at large are faring is incomplete.

The morning wound up with an important message to anyone passionate about moth and insect conservation: keep working at collecting the data, keep submitting records, lend your voice as an ambassador for insect surveying where you can, and continue to learn and encourage learning.

NHBS In the Field – Telescopic Wi-Fi Video Endoscope

The Telescopic Wi-Fi Video Endoscope is the latest addition to our range of video endoscopes and is manufactured by the company behind the ever-popular Explorer Premium Endoscope. An endoscope is a fantastic piece of kit for any practicing ecologist, allowing you to inspect hard to reach or inaccessible locations. Typical examples of where endoscopes are used include checking burrows, bird nests and bat roosts, where direct visual access may be limited.

This model features quite a few changes in comparison to its predecessors. Although the camera is labelled as an endoscope, it is really a hybrid between a pole mounted camera and a traditional endoscope. All electrical and optical components of the camera are neatly contained in a cylindrical module measuring just 8cm x 2cm (excluding fixing points) which is quickly and easily mounted onto the included telescopic handle. The camera also comes with a 14cm long flexible arm, which can be connected between the camera and the handle to help when manoeuvring in awkward spaces. As the name suggests, the camera transmits footage over Wi-Fi and allows the operator to view a live feed wirelessly on a smartphone or tablet.

We tested this camera in several locations, including a few typical bat and bird boxes to gauge its overall suitability for different applications.

How we tested

In March 2021 we took a Telescopic Wi-Fi Video Endoscope out into the woods surrounding NHBS and simply attempted manoeuvring the camera into a few awkward and hard to reach locations; such as high up in ivy covered ash trees and over the edges of some of the more unstable riverbanks. Our aim was to try and gauge its effectiveness in extending a surveyor’s reach. We also tried using the camera to inspect several empty bird/bat boxes to see how it would measure up against a traditional endoscope in these situations. Additionally, we captured several images using the camera’s free to use ‘Smartcam Wi-Fi’ app.

It is important to note that it is an offence to disturb nesting Schedule 1 bird species and any bat roost without an appropriate license, hence we only inspected boxes we knew to be empty.

The fully assembled camera is incredibly lightweight, weighing little over a few hundred grams, and it comes with a semi-rigid compact carry case that we were able to fit easily into a rucksack.

The camera is powered by a built-in Lithium-ion battery. We charged the camera, using the included USB-C to USB-A cable, for approximately 70 minutes as indicated by the manual supplied with the camera. On a full charge the camera can operate for a total of 90 minutes which was more than sufficient for our needs.

What we found

Connecting the camera to a phone was quite simple. Once we had downloaded the Smartcam-Wi-Fi app, all we had to do was turn on the camera module and connect to its Wi-Fi signal on our phone. It is helpfully called ‘SmartCam-XXXX’ so it is easy to identify. The app has several controls for the camera, including LED brightness, freeze (holds the image displayed until turned off), capture image and start/stop recording. The adjustable LEDs were a very handy feature and allowed us to maintain the optimum light settings when using it outdoors or inside a nest box. One frustration we had with the app was that it lacks an option to rotate the video feed, meaning that it is often necessary to rotate your phone to maintain the correct orientation. Because of this it would be worth investigating whether there are alternative apps more suitable for using with the camera.

Despite the limitations with the app, we were very pleased with the picture quality of the camera. Certainly, the 720p resolution is noticeably better when compared to an older style Explorer Pro endoscope, which has a slightly lower video resolution of 420p. When fully extended you do have to be careful in holding the camera steady as the image clarity can suffer a bit from camera shake. A nice feature of the camera is that it is waterproof to an IP67 standard, meaning we were able to submerge it briefly to inspect areas of the local river. One thing to note here is that while it was fine operating underwater, the Wi-Fi signal was severely reduced, and it was not able to maintain a stable connection for very long.

Other than when using the camera underwater, the Wi-Fi signal from the camera was very reliable. When testing the camera indoors we were able to maintain a high-quality live feed at a distance of around 15m with a clear line of sight. Certainly, in the field this was somewhat reduced by obstructions, but we found that the signal was still sufficiently strong with a distance of at least 10m between the camera and our smartphone.

The extended reach of 1m was useful, however we felt in most cases a surveyor would benefit from a greater total extendable length. The supplied handle does feature a thread at its base, meaning it would be possible to attach an additional handle to increase the overall reach. We found the flexi arm provided with the camera was sufficiently strong and allowed us to quickly adjust the camera angle or manoeuvre the camera into an awkward area when using it out in the field.

Investigating thick ivy with the endoscope at full extension

When attempting to use the camera with our nest boxes, we found that for boxes designed to suit larger birds (Barn Owls, Tawny Owls, Kestrels etc) the camera was easy to use and the benefits to workers looking to inspect these boxes were clear. However, its usefulness in inspecting bat boxes and garden bird boxes was more limited. The narrow crevice entrances of most bat boxes are simply too small for the camera to access, and a traditional endoscope style camera tube would be more appropriate in these instances. The 20cm diameter camera body could fit through the entrance holes of most bird boxes; however, it was not always possible to angle the camera as required and still fit it through the entrance hole of the box, meaning that the base of the box was not always visible.

Our opinion

Overall we found that, while the Telescopic Wi-Fi Video Endoscope is not always as effective as a more traditional style endoscope and the associated app is limited by certain design flaws, its affordable price, ease of use and versatility make it a great piece of kit for more general ecological surveying.

The Telescopic Wi-Fi Video Endoscope is available on the NHBS website.

Author interview with Dean R. Lomax: Locked in Time

Dean Lomax digging up dinosaurs at the Wyoming Dinosaur Center.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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