Faunus Nature Creations is an ecological design agency established in 2018 as a subsidiary of NatuurInclusief. They focus on designing, building and selling fauna facilities to create nature-inclusive urban living environments and are widely recognised for their creative nest boxes. Most of their products are made in-house and they work closely with their suppliers and partners to ensure both functionality and beautiful design.

We had the opportunity to speak with Jarno Beijk, the founder of Faunus Nature Creations, about the company, their range of nest boxes and plans for the future.


What inspired the creation of Faunus Nature Creations?

Faunus Nature Creations (FNC) was founded in 2018 as a business unit part of ecological consulting agency NatuurInclusief.  At NatuurInclusief we regularly had to deal with mitigation projects as compensation for bat roosts getting disturbed. During field checks of these bat boxes, we discovered that the quality of the materials used were rapidly deteriorating. They did not meet any of the quality requirements and longevity that we wanted and expected from the bat boxes. From this moment the only solution we saw was to roll up our sleeves and design and build better nest boxes ourselves. Currently we are doing this with a team of ecologists, designers, engineers and architects. 

Could you tell us about the range of boxes produced by Faunus and which animals they are suitable for?  

In the beginning, our main focus was on roost boxes for bats, and nest boxes for House Sparrows and Swifts. The reason behind this choice is because they are the most strictly protected species by law. Fortunately, there is increasing awareness of building and designing in a more nature-inclusive manner, which means that there is increasing interest in nest boxes for other species as well. This includes species such as Kestrels, Storks, insects, and ground dwelling mammals etc.

Many of the boxes you offer are made from wood concrete. Could you tell us some of the benefits of using this material, both for the user and for the animal?  

All our fauna facilities are designed with the needs and requirements of the species in mind. Wood concrete has a long lifespan, also the hydrothermal modified wood that we use has a lifespan of more than 20 years. It is therefore mainly down to the preference of the user.

Wooden facilities are not suitable as a build-in option. For this, the better choice is going for wood concrete or even better for a ceramic option. The latter have the longest longevity. 

A great disadvantage of using wood-concrete and ceramics is that they do not lend themselves well for custom work. Therefore, wood is a very good option for custom work. That is why we make custom wooden bat boxes on request in all kinds of shapes and sizes. When customisation is required to be built-in, we make these on the basis of a cement board. 

Personally, we think wood is the most beautiful for external use, because it looks more natural, but other people appreciate the concrete look as well. You will not easily find plywood in our collection, because we find this material is insufficiently durable and has too short of a lifespan. 

Many of my colleagues have taken a liking to the names of your boxes, for example, Elisa and Gabriella. How do you decide these names?

Every nest box or new design we develop and offer is a new family member to our collection. Each design therefore deserves a unique name and not just a code or number. The intention was to use the names of people in our team first, but some found it quite embarrassing if they had to promote a nest box that would bear their own name. We have therefore given the names a slightly Spanish twist. So, Roos became Rosita and Eva became Evita. Spanish names also sound more swinging than Dutch names. At the moment we have more models than employees, so we have now arrived at names of relatives, neighbours and friends. Our latest model nest box Milo is named after the newborn son of our colleague Roos. Furthermore, the mammal nest boxes have female names, and the bird nest boxes have male names.

Have you found that environmental regulations have had an impact on the boxes you sell? 

In the Netherlands we have a quite strict Nature Conservation Act. Our authorities require many strict mitigation standards concerning fauna facilities, for example in the form of bat roost boxes and nest boxes. This is a major reason that many of our clients need to buy the products we make. We ourselves are not in favour of this strict legislation, because people will lack intrinsic motivation to do something good for biodiversity in the end. We ourselves believe that you can achieve more for biodiversity if you know how to make people aware and enthusiastic to do something positive for biodiversity. Legislation of this mitigation standards leads to “must do”, enthusiasm leads to “wanting to do”.

What can you tell us about plans for new products in the future? 

Faunus Nature Creations does more than just develop fauna facilities. Of course, we will bring new and improved models to the market, but we also design many large custom facilities for biodiversity, such as designing and building bat towers. We noticed that there is a great need for this as well. Governments and project developers would like to show off that they are doing something great and important to boost biodiversity and they would like to have the label extravagant for that too. We think it’s a sport to combine functionality, quality and aesthetics. Our motto is not without reason: Building for Biodiversity. Let’s create something valuable!

Author interview with Graham Tucker: Nature Conservation in Europe

This informative and wide-ranging book examines the nature conservation responses of the UK and twenty-five EU Member States, analysing their achievements and failures and providing notable case studies from which comparisons and lessons can be obtained. Covering topics such as biodiversity pressure, legislation and governance, biodiversity strategies, species protection, protected areas, habitat management and funding, the book provides an incredibly in-depth appraisal of our management of European ecosystems and species and how this has contributed to the current concerning state of nature in these regions.

Editor Graham Tucker is an ecologist and a leading authority on European nature conservation policy, with a particular interest in its achievements and failures. He currently works as an independent consultant and proprietor of Nature Conservation Consulting. Prior to this he worked for Birdlife International and as Head of the Biodiversity Programme for the Institute for European Environmental Policy.

We recently chatted with Graham about the book and about the necessity for international co-operation in conservation, the importance of funding, stakeholder engagement and societal support in the creation and maintenance of protected areas, plus his plans for the future.


This is an impressive endeavour into covering the enormous topic of conservation across Europe. What inspired you to create this book?

Several things drove me to prepare the book. Firstly, like many others, I am concerned by the ongoing decline in many species and degradation of habitats in Europe, and that nature conservation has not been able to halt, let alone reverse most losses. Whilst there have been successes for some species, they have been insufficient, and consequently biodiversity targets have been repeatedly missed. Secondly, having had the privilege to work over the last few decades with many nature conservation experts across Europe, I realised the reasons for these failures varied between countries. Whilst the broad approaches to nature conservation have been similar, there have been significant differences, especially in their implementation and outcomes. Comparing national experiences could therefore provide valuable lessons in terms of which nature conservation measures have, and have not worked, and why. However, nature conservationists have tended to mainly draw lessons from national experiences, in part because of language barriers and the other difficulties with finding relevant key information.

Therefore, there seemed to be a need for a book that describes and critically examines the nature conservation objectives and actions that have been taken in Europe, primarily through individual country chapters written by national experts with a deep knowledge of what has really happened. Having discussed the idea with some nature conservationists I found that there was considerable enthusiasm for the book and many willing to contribute, despite the huge amount of work it would involve. This was also inspiring and persuaded me to go ahead as its preparation has depended on the hard work, generosity and patience of many people; of which I am especially indebted to the 52 co-authors.

Chapter 3 discusses the international drivers of nature conservation and their impacts on policies in Europe. How important is international co-operation and coherency in policy to nature conservation? Do you think there is enough large-scale international conservation?

International cooperation and coherence are vital for effective nature conservation. This is most obviously the case for migratory species, as well as rivers, seas and ecosystems that cross national borders, and transboundary protected areas. This has been widely recognised, so there is now a reasonably complete nature conservation framework in Europe, including the global UN Convention on Biological Diversity (CBD), the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention) and, of most influence, the legally binding EU Birds and Habitats Directives. These agreements have aided cooperation such as through sharing programmes of work, knowledge and funding. Most importantly, they have helped raise ambitions by creating a level playing field – which gives countries the confidence to act, knowing that they would not be alone.

Unfortunately, the UK’s departure from the EU has undermined this cooperation and alignment, resulting in potential divergence in ambitions, policies and legislation, both between the UK and EU and between the UK nations. So far there has been little divergence in UK practices and standards are being maintained. But this could change with time, especially in England as a result of the Retained EU Law Bill.

Chapter 5, ‘Conclusions, Lessons Learnt and Implications for the Future’, mentions that, while nature conservation has likely slowed the rate of decline, many habitats such as wetlands and semi-natural grasslands forests have continued to be lost or degraded. Do you think large-scale commitments such as the one to increase the UK’s and EU’s protected area network to 30% of both land and sea by 2030 will generate the right amount of funding, stakeholder engagement and societal support to create effective, large-scale conservation?

I am sure there is wide public support for the improvement and expansion of the protected area network, both on land and sea, in the UK and elsewhere in Europe. This is because the potential nature and wider related social and economic benefits of protected areas are increasingly appreciated. However, in most countries it is more important to improve the effectiveness of the existing network, in particular with stronger nature conservation objectives and better practical management. This requires more funding and stronger regulation, which I am doubtful that most governments are currently committed to.

This chapter also mentions that nature conservation is dependent on enforced legislation, funding and motivated people. Which do you believe is the hardest to obtain and therefore is the biggest threat to current and future conservation efforts?

All three are needed, and they are to some extent interrelated and dependent upon each other. However, the lack of funding, which is in part due to insufficiently motivated politicians, is currently the main constraint in most countries. This hampers the enforcement of legislation, as well as limiting practical nature conservation and restoration actions in protected areas and the wider environment.

Whilst public support for nature conservation is substantial in many countries, especially the UK, it varies greatly. Political support also tends to lag behind public support, in part due to the influence of powerful lobbying groups. Wider and deeper societal engagement is therefore essential to stimulate stronger political support, funding and regulations. It is therefore encouraging that support for nature conservation is growing. This is needed now to counter recent calls from some politicians in the UK and EU to weaken some environmental ambitions and slow down actions.

What impact do you hope that this book will have?

I hope that the book will clearly show that nature conservation works when it is properly implemented – such that it can halt biodiversity declines and even restore ecosystems. Therefore, the ongoing biodiversity crisis is not because we are doing the wrong thing. On the contrary, we need to massively scale up what we are doing already. As said, we know what we need: strong and enforced regulations, more and better targeted funding, and more deeply motivated people to call for and help conserve nature. We should still seek to improve the effectiveness of nature conservation measures, basing policy and practical decisions on evidence, but be wary of calls for radical changes in approach.

Of all the countries discussed within this book, which do you believe are leading the way in nature conservation?

Unfortunately, this is not easy to answer as it is often difficult to reliably compare data across the countries. For example, some countries have large protected area networks (e.g. Croatia, Slovakia and Slovenia) in contrast to others (e.g. Belgium, Finland, Ireland and Sweden). However, the statistics are not always reliable as some countries, such as Bulgaria, Denmark and UK include areas that do not meet internationally recognised protected area definitions. Furthermore, the effectiveness of protected area network is not necessarily closely related to their size, but more their conservation objectives and the effectiveness of their practical management. Similarly, comparing the adequacy of funding is difficult because needs vary and it is not always clear how much goes towards species and habitat conservation priorities, and what it actually achieves.

As described in some detail in the conclusion chapter, all countries have both strengths and weaknesses, so it is difficult to identify overall leaders. As regards the UK, we have been leaders in some respects in particular in relation to science and the strong role of NGOs, and producing a wealth of strategies, including the first Biodiversity Action Plan in the world in response to the CBD. However, the UK has underperformed overall, primarily due to poor implementation of its strategies and other initiatives, largely as a result of limited political support and therefore weak regulations and inadequate funding.

Do you have any future plans that you’re able to share with us?

As the book has taken over five years to prepare, I am having a bit of a break from writing for the moment. But I am continuing to work on EU and UK nature conservation issues, especially in relation to climate change.

The impacts of climate change on nature are of growing concern to me, as I think they will be much worse than many people realise. In addition to the increasing disruption to ecosystems, there is the likelihood of huge impacts from climate change mitigation measures and adaptation actions over the next 30 years. Whilst it is essential to reduce greenhouse gas emissions, many proposed responses can be highly damaging for nature, including widescale inappropriate afforestation, use of bioenergy, solar farms and hydro-energy. Damaging climate change adaptation measures are also likely to increase, such as increased water abstraction from wetlands, as is already affecting the Coto Donana in Spain. At the same time, well designed ecosystem-based measures can contribute substantially to mitigation and adaptation, whilst being beneficial for nature – but these are being underused. Maybe, in time, I will prepare a book on this.

Interview with Jan Collins: Bat Surveys for Professional Ecologists 4th Edition

Purple cover for Bat Surveys for Professional Ecologists with lots of images of bats.The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is the latest update of the Bat Conservation Trust (BCT) Guidelines and features new content on biosecurity, night-vision aids, tree surveys and auto-identification for bat sound analysis. Several key chapters have been expanded, and new tools, techniques and recommendations included. It is a key resource for professional ecologists carrying out surveys for development and planning.

Portrait image of the author Jan Collins

Jan Collins is the Head of Biodiversity at the Bat Conservation Trust and a former ecological consultant. Her fascination in bats began when participating in a bat biodiversity survey on a Vietnamese expedition in 1999 and she has worked in bat conservation ever since. She has been in her current role for the last 10 years and has played a central role in the editing and refining of the BCT Guidelines.

In this Q&A we had the opportunity to speak with Jan about some of the key aspects of the 4th edition of the BCT Guidelines and its consequences for ecologists.


What led you towards a career specialising in bats?

From a young age I was interested in being outdoors and engaging with nature. My studies followed this route, with a degree in Environmental Sciences and a Masters in Ecology and Management of the Natural Environment. I was first introduced to bats on a Frontier expedition to Vietnam in 1999 where we were trapping bats as part of a biodiversity survey. I was immediately hooked (what an amazing group of animals, with unique behaviours, and so very diverse!) and sought both voluntary and paid work involving bat conservation upon my return. I was an ecological consultant specialising in bats for over 10 years before joining Bat Conservation Trust in my dream job as Head of Biodiversity almost exactly 10 years ago now.

Could you tell us briefly about the work that the BCT does?

BCT is a dynamic, influential and growing national charity. We are the leading non-governmental organisation in the UK devoted solely to the conservation of bats and their environment. Our work represents the gold standard in bat conservation providing a lead for the rest of the world. We work to ensure that bat conservation is acknowledged as an integral part of sustainable development. Our work ranges from best practice guidance, advice and training through to engaging wider audiences so that we can get more people to understand the importance of bats and their conservation. A lot of our work also involves working with partners on the ground, local bat groups play a huge role in all aspects of our work. More information about all of our work can be found in the most recent annual review, found here or take a look at the Bat Conservation Trust Website here.

The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is due to be published in September 2023. What have been some of the key challenges in getting this ready for publication?

One of the key challenges for this edition was gaining consensus from the Technical Review Board on some of the recommendations. This included the continued use of transects for bat activity surveys and how tree surveys for bat roosts should be carried out, acknowledging the various limitations, and how approaches should be adapted to different types of projects. Another challenge has been how much to include on night vision aids such as infrared cameras. BCT are planning a kick-off meeting for a working group to develop separate night vision aid guidelines in the autumn (to include infrared and thermal imaging cameras) and therefore many aspects are still to be discussed and decided. We will also run a public consultation on night vision aids to help us to understand current practice and expectations from new guidelines on this topic.

How has the outlook for bat populations in the UK changed since the last edition of the Guidelines?

Data from the National Bat Monitoring Programme indicate that populations of the bat species we monitor in the UK are stable or recovering. However, it should be remembered that these trends reflect relatively recent changes in bat populations (since 1999 for most species). It is generally considered that prior to this there were significant historical declines in bat populations dating back to at least the start of the 20th century. This suggests that current legislation and conservation action to protect and conserve bats is being successful, and it is vitally important that this continues. Detailed information on trends for the 11 species monitored can be found in our National Bat Monitoring Programme reports here. We are also seeing signs of regional variations that deviate from the overall positive trend at the national level and we want to gain a better understanding of those. More data would help this process so we would encourage everyone to join in with one or more of the National Bat Monitoring Programme surveys. There are surveys that are suitable for anyone regardless of experience or equipment.

What are some of the key changes in the Guidelines?

A number of chapters have been expanded and new tools, techniques and recommended best practice incorporated. Below are a few of the changes but we will be developing a webinar in the coming months, detailing all of the changes so readers should watch out for that!

  • A new section on Biosecurity has been added to Considerations for Bat Surveys chapter, recognising that precautionary approaches are needed to protect both ecologists and bats from potential health risks.
  • Chapter 6 on Surveying Trees and Woodland for Bat Roosts has grown from five pages in the 3rd edition and now includes details of newer technologies and sources of information such as night vision aids, motion activated camera monitoring, The Bat Tree Habitat Key and the Bat Roost Tree Tag Project as well as updated guidelines for categorising the suitability of potential roost features.
  • Chapter 7 focuses solely on dusk emergence surveys, with dawn re-entry surveys removed as a standard approach due to the improved quality of emergence surveys with night vision aids and the variability in the time that bats return to their roosts.
  • Chapter 10 on Data analysis and Interpretation incorporates information on auto-identification systems and has a new section on data science which includes details on elements such as tidy data, minimal data requirement and data standardisation. There are also case studies to help illustrate key points.

How will the new Guidelines improve the way ecologists approach bat surveying?

The guidelines are the key resource for professional ecologists carrying out surveys for development and planning. The Biosecurity section in the 4th edition will ensure that ecologists carry out their work in a safe way, minimising health risks to both themselves and to bats. The latest edition acknowledges the constraints involved in surveying trees for bat roosts and offers different approaches to surveys depending on the nature, scale and timeline of the project. A new categorisation system for Potential Roost Features (PRFs) and trees reduces the subjectivity in initial assessments of trees. Dawn re-entry surveys are no longer recommended as there are questions around their efficacy for presence/absence and because emergence surveys can be vastly improved by the use of night vision aids. A stepwise approach is offered to those using auto-identification systems to analyse acoustic datasets and the section on Data Science aims to standardise approaches to data management. The guidelines also make reference to a wealth of resources that can be used to improve surveys and, in particular, interpretation of survey data.

Nocturnal survey equipment such as night vision, thermal imaging and infrared cameras are becoming more important in bat survey with the 2022 Interim Guidance Note providing clarification of their role. How will the 4th edition of the Guidelines impact the way ecologists conduct bat surveys using these types of equipment?

The 4th edition supercedes (but is consistent with) the Interim Guidance Note published in May 2022. It emphasises that surveys should usually be carried out with night vision aids and that if they are not used this should be justified in reporting, with reasons provided (e.g. at known roosts when bats are known to emerge early or in situations/locations with higher levels of natural or artificial light). Dawn re-entry surveys are no longer recommended as a standard approach because the use of night vision aids vastly improves the quality of emergence surveys, when used properly. The new guidelines state that a still shot must be taken at the darkest point of the survey to show the field of view and that appropriate illumination has been used. They suggest that the use of night vision aids can be used to reduce the number of surveyors but only if the cameras/lighting reliably match or exceed what a surveyor can achieve, with evidence provided. See the 4th edition for more information on use of this equipment!

BCT are planning a kick-off meeting for a working group to develop separate night vision aid guidelines (with much more detail) in the autumn (to include infrared and thermal imaging cameras) and therefore many aspects are still to be discussed and decided. We will also run a public consultation on night vision aids, to help us to understand current practice and expectations from new guidelines on this topic.

Author interview with Arnold Cooke: Tadpole Hunter

In Tadpole Hunter, author and conservationist Arnold Cooke provides us with a personal and unique insight into the history of amphibian conservation and monitoring within Britain. As well as telling the story of amphibian natural history since the 1960s, it also provides a very human perspective on how we got to where we are today and how our knowledge of amphibian populations and dynamics has progressed over the second half of the 20th century. Packed with wonderful photographs along with charts and tables representing monitoring data, this accessible book will appeal to anyone interested in amphibians and the history of conservation in Britain.

Arnold Cooke was a researcher and advisor for the the Nature Conservancy and Natural Conservation Council for 30 years. Since leaving English Nature in the late 1990s he has continued to pursue his interests in amphibians, birds and deer and has published widely on subjects as diverse as the status of Britain’s amphibians and reptiles, pollutants in birds and the environmental impacts of introduced species of deer. His previous book, Muntjac and Water Deer, was published in 2019.

In this Q&A we chat with Arnold about his work with amphibians in the UK, the changes he has seen during his years working in conservation, and his hopes for the future of amphibian populations.


Although working with amphibians and their conservation has been a key part of your career, you have also dedicated a lot of your free time to recording and monitoring them and adding to the general body of knowledge regarding their populations. What is it about amphibians that you find so fascinating?

Amphibians have always appealed to me particularly because they can be relatively easy to catch – at least for vertebrates. However, they could be quite scarce where I grew up, and as a boy I was more interested in birds, flowers and invertebrates. When, in 1968, I joined the Nature Conservancy team studying the impacts of pesticides on wildlife, there were indications that frogs had declined, possibly because of pesticide use. An attraction of such a project was that there were significant gaps in knowledge about the natural history of frogs and other amphibians. This meant I had a fairly blank canvas at the beginning and I needed to undertake basic studies to try to understand what made frog populations tick, as well as doing pesticide studies. Later, I joined the Nature Conservancy Council, and became involved with conserving amphibian species nationally. By then I had started studying amphibians in a personal capacity, and was able to adapt or start local projects to inform issues of national interest, such as developing monitoring methods and investigating population stability and responses to impacts of various kinds. As information from these studies became available, it could be fed back into the system to conserve amphibians – and so helped me do my job more effectively. Once started, I became increasingly hooked and often found it difficult to stop the various strands of work.

You mention how, early in your career, you were faced with the challenge of discovering how populations of amphibians had changed in the distant and recent past and that, given the lack of empirical field data, sending questionnaires to suitable candidates was the best way to gather information about this. Do you think that conservation initiatives for amphibians are still limited by accurate population/distribution data?

When I started to work on the common frog more than 50 years ago, there was no hard information on how the national population had changed, but several well-informed individuals considered that declines had occurred. I felt I needed to be sure that there was a problem before doing too much work on pesticides and should find out whether, where and when decreases might have occurred. I targeted those people in the British Isles who had observed frogs (and common toads) in their local ponds and this resulted in information from several hundred sites. To increase cover I asked biology teachers in schools about changes in their local populations. The consensus was that there had been widespread decreases for both species during the 1950s and 1960s. This technique had obvious flaws, but its overall conclusion seems broadly accepted. However, it is wise to acknowledge the drawbacks of the method and not to place too much credence on the resulting information, especially on reasons that might be offered for change. Where ponds were destroyed (or created) in an area, then there are tangible reasons for change. However, this is often not true for suggested contributions such as from collection, road mortality or, indeed, pesticides. Because of the population dynamics of amphibians, substantial changes occur naturally and loss of some individuals does not necessarily translate into population decline.

During later decades of the twentieth century, several similar studies were undertaken, but since the turn of the century an attempt has been made to set up a statistically sound monitoring system for the widespread amphibians and reptiles. Unfortunately, number of sites covered initially was insufficient to provide a completely satisfactory basis for the scheme to go forward in that form. Consequently some modifications and compromises were needed, and a new approach has now started. Progress is being made employing novel field, laboratory and computer methods. And I am hopeful that herpetologists can continue to tap into citizen science projects on other animal groups, particularly birds, where huge numbers of competent individuals might be organised to gather additional data on amphibians.

I should also say that knowledge of the much rarer natterjack toad is exceptionally good. All known colonies are recorded regularly, and some have been monitored continuously for 50 years. This has allowed fine tuning of conservation action at specific sites and more broadly. And the very rare pool frog receives constant attention at its introduction sites.

As someone that worked at the forefront of conservation for many decades and has seen a huge number of changes, both in the natural world and in the human organisations and councils that are charged with protecting them, are you broadly hopeful for the future of British wildlife?

Thank you for the compliment, but I’m not sure how long I’ve spent at the ‘forefront of conservation’ – especially during the last 25 years when I’ve deliberately busied and buried myself in the detail of my own interests. Throughout my life, I’ve worked as a specialist in a range of disparate areas, rather than as a rounded generalist, so I’ve tended to focus on specific issues within the broad spectrum of wildlife conservation.

It’s true, however, that I’ve seen huge changes over the last 55 years. Some changes are of great concern – no one 50 years ago saw global warming coming. I remember there was talk about 40 years ago of the possibility of another ice age being just round the corner. The changes in biodiversity over that time have of course mainly been losses. On the other hand, there have been other types of change providing hope that British wildlife does have a reasonable future. I am thinking, for instance, of the numbers of professional people and volunteers now involved in conservation, the knowledge that has accrued, the conservation methods that have been shown to work and the legislation that has been passed. I’m aware that successive governments haven’t necessarily dealt kindly with environmental issues (or conservationists), but many peoples’ attitudes have changed markedly and younger generations are especially concerned about the environment. Just as conservationists in the past achieved more than might be expected because of their dedication, so should conservationists of the future – and there will be many more of them.

The wildlife communities and their distribution will, though, probably look very different in the future. I have lived for 55 years on the edge of the Cambridgeshire Fens. That area doesn’t sound very promising for wildlife, but I was pleasantly surprised to discover in 1968 that there were several nature reserves within easy reach including three important National Nature Reserves. However, I soon realised that reserves were like currants in a cake, there being very little of interest between them. When my wife and I drove to Norfolk to visit three other NNRs, we only managed to find one of them, despite knowing their grid references – and we had to negotiate a barbed wire fence to get into that. A permit was required for access in those days. The situation is of course very different now: visitors are generally welcomed. And reserves are increasingly being connected up, as is occurring in my area with two of the NNRs. I don’t doubt that much of our biodiversity will in future be experienced inside landscape-sized areas. I just hope it works. I regret that kids today don’t have the freedom that I had to explore and find things out for myself. Presumably, however, accessibility of knowledge will continue to increase. No need for children to learn and remember much, just use the phone app. Not wishing to be too cynical, surely enough youngsters will be captivated to become the dedicated conservationists of the future?

As regards amphibians, I believe we have more or less stopped the declines of the twentieth century and recoveries have started for some species. The future is uncertain but there are reasons to be hopeful.

Your working life has been incredibly fascinating and varied. Are there any parts of it that you remember with particular fondness or that stand out in your memory?

I’ve been very lucky with what I’ve been allowed or managed to do during my working life of more than 60 years – that’s using the word ‘working’ very loosely. I still have a reasonably good grasp of what I did and when I did it because I’ve usually written up (but not necessarily published) my observations and thoughts in some form or other. When I’ve been able to study wildlife, there has been very little that I haven’t enjoyed. There have been stand-out moments such as: in 1962 when I found my observations demonstrated that birds in suburbia were more approachable than those in the countryside; in 1982 when I watched breeding newts by torchlight for the first time; and in 1994 when I realised I could put out tempting vegetation for muntjac in a wood and find it had been consumed by the following morning. Each of these moments led to the development of field monitoring techniques.

Then there have also been periods that have been memorable for different reasons. The five years 1968-1973 with the old Nature Conservancy at Monks Wood were marked by an extraordinary level of interest in our work shown by the public, politicians and even royalty. In contrast, the last couple of decades have been spent quietly at home pottering around doing as much fieldwork as possible and sorting out what results meant. My qualifications are in chemistry and biochemistry and, had things turned out differently, I might have been more of a lab worker. But working outside has always been my preference. When working for English Nature in the 1990s, we were required to fill in risk assessment forms when away from the office, including when working outside normal office hours. Some years, I filled in nearly 200 such forms, revealing how much fieldwork I did as well as providing an illustration of why I was glad to leave behind modern management methods in the late 1990s.

What would be the main message you would give to the conservationists and ecologists that are following in your footsteps?

Because of my rather blinkered working experience during the current century, I think the most appropriate message is simply to say, ‘good luck and thank you’. Everyone needs some luck in order to have a satisfying career and I genuinely appreciate what present and future generations are doing and will continue to do to help understand and conserve wildlife.

Finally, what is occupying your time at the moment? Do you have plans for further books?

My main task this year has probably been seeing Tadpole Hunter to fruition, so it’s good to have it published at last. I’d wanted to review some of the topics in the book for many years, but they’ve only appeared in book form because of the Covid pandemic. My wife and I needed to shield during the lockdowns, so I started to review a couple of subject areas in March 2020. Later that summer, I realised that I had the basis for a book, so roughed it out and continued writing. I don’t intend writing another book, in part because of the time commitment. While writing Tadpole Hunter, I published several items on deer and have vague plans for other articles once the dust has settled from the book.

I have occasionally tinkered with bird behaviour in a very simple way and may revisit data collected in the 1980s. Earlier this year, I was surprised and very pleased to be invited to contribute my historic data to a global database of avian ‘flight initiation distances’, which precipitated a dive into material I hadn’t looked at for many years. Another line I might pursue concerns citizen science. I’ve participated in a number of such projects over the years, recording birds in particular, but also mammals and trees. At the moment, I’m interested in what an individual participant could get out of it? If repeated annually, it can provide useful monitoring information on species at your location. In some instances, I have carried on recording for long after the citizen science project finished.

Although I’m now doing very little fieldwork, I still have ideas to explore, but I’m sure there won’t be another book unless……….

Author interview with Mark Avery: Reflections

cover for the book reflections with hillsides covered with animals and flowersReflections is a passionate commentary on the state of nature and conservation in the UK. In it, Dr Mark Avery explores the current condition of wildlife, why wildlife conservation is failing and what can be done to reverse its plight. He examines the role NGOs, land owners and government have in its failure, and crucially examples of successes too. Reflections is a valuable resource for those wondering what exactly is going wrong in nature conservation and what action can be taken to remedy this.

Picture of mark avery

Mark Avery is an author, blogger and former director of conservation at the RSPB where he worked for 25 years. His previous works include Inglorious where he examines grouse shooting in the British uplands, and Remarkable Birds, a compendium showcasing the extraordinary wonders of the birds that share our world. We had the opportunity to speak to Mark about how he came to write Reflections and some of the key themes from the book.


Could you tell us about how you came to write Reflections?

I guess there are at least three reasons for writing a book. First, that you have a great imagination and can tell scintillating stories. Well, that’s not me and I write non-fiction, though I have wondered about a fictional book about nature conservation and nature conservationists. Second, you have some amazing experiences that you want to share with the world. That’s not me either. Third, you think you have ideas about the world that will be useful to others, and that’s the category that Reflections is in. I have worked in wildlife conservation for over three and a half decades and so I’ve lived the issues about which I write, but I’m not writing about my experiences, I’m writing about my thoughts, ideas and take on the world. Those ideas were bubbling up so much that I thought I’d write them down. It felt a bit like a pressure valve being released. The good thing from my point of view is that it seems that lots of other people relate to my thoughts. That’s thrilling for any author.

How do you think people’s attitudes towards, and awareness of wildlife have changed in your lifetime?

I was a teenager 50 years ago so looking back to then, animal welfare concerns, which aren’t quite the same as conservation concerns but are mixed together in all of our heads, have grown enormously. That affects how people think of field ‘sports’, predator control, snaring etc. I welcome many of those changes in attitude. Climate change has come along and dominates, rightly, the environment scene, and that has implications for wildlife conservation. I sometimes think that nature conservation is a bit squeezed between welfare issues and hard environmental ones. But over that period conservationists have moved from playing in small nature reserves and chasing people persecuting wildlife, to a greater force having some influence (not enough!) on big public policies such as farming, forestry and fisheries. We need to develop more strength in those political realms if we are to see nature recover.

You talk in Reflections about situations where considerable gains in wildlife conservation can be obtained in exchange for small losses in profit from land use activities. How do you think land managers can be convinced to take the hit to their profits for the benefit of wildlife?

With respect, I don’t accept the premise of the question. It is utterly pointless to try to get a vested interest like agriculture (house building, private forestry, shooting etc.) to act for the public good. Our wildlife conservation bodies are too timid and nice to realise that is a dead end. One has to jump over the heads of such industry representatives and persuade the decision-makers directly to implement public policies that deliver public goods. Focus effort on the decision-makers!

In the book you frequently mention the trade-offs between the state of wildlife in the UK and living standards. How do you think we can we balance the need for government investment in wildlife conservation and in critical public services like the NHS?

I’m glad you noticed that – we live in a complex human world and most people don’t give a stuff about wildlife. The partial answer to that question is that spending on wildlife conservation is tiny – that’s why it doesn’t work very well. It could increase many times over and still be tiny compared with other expenditures. It would be a false dichotomy to say we can have either a thriving wildlife or a thriving NHS, but I concede at the moment neither is thriving. Another partial answer is that governments should use more regulation (‘thou shalt not’s) rather than spending money on persuasion. They are cheap for the public purse. And of course, there are real benefits, that have economic valuations, in having wildlife-rich landscapes that flood less (or less damagingly), store more carbon and make people happier. But it’s a big subject. Give me a list of government spending across departments and I’ll cross a few things out (I might start with nuclear warheads) but your list would be different from mine, I guess.

You mention that the number of people actively interested in wildlife conservation is relatively small. How can we get more people to care about wildlife in the UK?

This is what our wildlife NGOs would call recruitment, or growing their memberships. The trouble is, it’s easier to recruit members than committed members interested in nature conservation. The National Trust’s five million members are arguably a weaker force for good that Wild Justice’s zero members but 35,000+ newsletter readers (but I’m maybe biased there). I think we could get more nature conservation done, particularly more impact on government policies, by getting existing members more mobilised than we could by getting more members. We have a small army of devoted conservationists – it’s just that they aren’t well armed with facts and tasks. Having more badly equipped troops isn’t a great recipe for success, I feel.

Do you think it is likely that we will see an improvement in the state of wildlife in the UK?

I can’t say that it is likely but it is certainly possible – but impossible with business as usual. We, and this means our largest wildlife charities, need to get much better at influencing land use policies. That’s entirely feasible but needs a change of mindset. I hope Reflections will encourage that change of mindset.

Do you have any plans for further books that you can tell us about?

I always have ideas, I have two at the moment, but sometimes they come to nought, so I’m not telling! Watch this space!

Author interview with Fiona Mathews and Tim Kendall: Black Ops & Beaver Bombing

Black Ops & Beaver Bombing: Adventures with Britain’s Wild Mammals is a captivating and entertaining deep dive into many of the mammals of Britain. Fiona Mathews and Tim Kendall explore mines inhabited by great horseshoe bats, go on overnight stakeouts in search of pine martens and travel from Scotland to the Isles of Scilly in search of their elusive subjects. This book puts animals at the heart of the story, revelling in their peculiarities and exploring the threats to their survival and the struggles that plague their conservation in Britain. The depth of knowledge, witty commentary and obvious enthusiam creates a beautifully written book that is difficult to put down.

Each chapter focuses on a different UK mammal, from wild boars and beavers to red squirrels and grey seals. Fiona and Tim explore the history, ecology and current conservation of these species, focusing on what is threatening them and what should or is being done to protect them. They do not shy away from giving criticism and sharing their frustration when the attitudes of policy makers stand against environmental protection and restoration. In search of answers to the problems that beset our wildlife, the authors reveal the wonder of creatures that are worth fighting for.

Fiona Mathews is a professor of environmental biology at the University of Sussex and the founding chair of Mammal Conservation Europe. Tim Kendall is a professor of English Literature at the University of Exeter and edited Britain’s Mammals 2018. They have kindly agreed to an extended interview with us, where we discuss the role of public education in conservation projects, how climate change may be impacting population recruitment in bats and seals, whether there is hope for the reintroduction of top mammalian predators, and much much more.


Could you tell us how you both became interested in mammals and what inspired you to create this deep dive into the mammals of Britain?

Tim: I grew up right next door to Devonport Dockyard in Plymouth. I was obsessed with spotting mammals as a child, but the only ones I ever saw were grey squirrels. When I was 8 or 9, I wrote a poem for school about seeing a badger, describing the joy and excitement I felt. It was all made up: I didn’t see a live badger until after I left for university. Luckily, I had the good sense to marry a mammal biologist and carry out fieldwork with her, which means that I’ve now seen all but three of our native mammal species.

Fiona: I’ve been interested in mammals for as long as I can remember, but I decided it should become my career after I went on my first bat walk. Black Ops and Beaver Bombing was partly inspired by my work reviewing the population status of Britain’s mammals and drawing up the Red List with the Mammal Society.

The preface, I-Spy, makes an interesting point about the interconnectedness of species as well as the focus of conservation: “If you want to save the barn owl, start by saving the field vole”. Do you believe the focus on ‘charismatic’ species, which are often higher up in the food chain, more often aids the conservation of prey species (such as by increasing or improving habitats) or harms these species by increasing the population of their predators? Should more conservation projects take a more ‘grassroots’ focus, by helping species lower down on the food chain?

We ignore the small species at our peril, and the fact that they’re almost all in decline is deeply worrying. Of course, wolves and wild cats grab the headlines, but if we don’t pay attention to the bioabundant species, everything across the food web is affected. We talk a lot in the book about the Scilly shrew, and if we’d thought anyone would read it, we’d have included a chapter on field voles.

In Chapter 3 ‘On the Trail of the Lonesome Pine Marten’, you discuss the extensive work done to win over the local people before the ‘recovery’ project began. Do you believe the public will become more and more open to these types of projects or will public education always need to play such an extensive role?

The general public is already becoming more welcoming, but the people who control landscapes are a small subset of the population, and they often have their own priorities that they believe (rightly or wrongly) will be damaged by reintroduction and recovery projects. One of the unfortunate things about rewilding is that it’s becoming as divisive as Brexit. We should all be working together to reverse the biodiversity crisis.

Wild mammals only make up between 2–4% of the world’s mammal biomass, decreasing by more than 85% since the rise of humans. In contrast, livestock makes up more than 63% of mammal biomass. How has this drop in wild mammal biomass impacted ecosystems and do you think we’ll be able to repair this?

High intensity livestock production is undoubtedly a massive contributor to biodiversity loss, but we mustn’t perceive farmers as the enemy. We need good farmers producing good food and getting rewarded for sustainable and wildlife-friendly production. Progress towards reforming agricultural subsidies has moved at glacial speed. Our government, like most across the globe, is much too heavily influenced by the lobbying of large agribusinesses which want to preserve the status quo.

In Chapter 5 ‘Hanging Out with Greater Horseshoe Bats’, you mention that Fiona is working on a long-term plan to re-establish the British population of the greater mouse-eared bat. Could you tell us a little bit more about how this process would work?

Fiona: Historically, the greater mouse-eared bat has been found in Dorset and Sussex, but with climate change we would expect its range to shift northwards. There are large and thriving colonies in Brittany and Normandy at the moment. We have to work out whether they will arrive in England under their own steam, or whether we need to give them a helping hand. Translocating bats isn’t easy. I’ve set up a working group at Eurobats to bring together experts looking at the best way forward.

You mention that the greater horseshoe bat population has stabilised and is now increasing in Britain. Why do you think this is happening?

The species is struggling across mainland Europe but it has responded well to a series of mild winters in England and Wales. Organisations like the Vincent Wildlife Trust have done a fantastic job to protect and improve roosts. We should remember, though, that greater horseshoes once had a range that extended to the east of England, and it’s estimated that there was a population of 300,000 at the end of the nineteenth century. The current population is about 4% of that total, which is a remarkable recovery from their lowest levels, but we need to be aware of shifting baseline syndrome before we celebrate the good news too enthusiastically.

Chapter 5 also mentions a new system for monitoring bats, which monitors the flight paths using radio receivers. Do you think that, by highlighting important flight paths, this system will be able to be used to reduce the impacts of new developments?

Although legislative protection means that we now know a lot about bat roosts in buildings, there’s not much point protecting a roost if the animals lack places to forage or mate. New techniques such as static radio tracking allow us to identify important sites and protect them for the future.

As cool weather in spring can have an impact on the growth and development of young bats, has climate change impacted juvenile survival rates and population recruitment?

We know that baby bats grow less well, with short- and long-term consequences, when weather conditions are poor in the breeding season. We would expect to see negative effects from climate change, and this is something we are currently looking at in a European-wide project. The challenge is that few researchers have datasets that span at least 20 years, which is the timeframe you need for analysing these long-term trends. So we’re also conducting other research on shorter timescales to assess whether mother bats are moving around their roosts to select different temperatures.

Chapter 6 ‘Tiggywinkle Goes Rogue’, mentions how ‘tidiness’ harms biodiversity. Do you think the growth in recent campaigns such as No Mow May will help to reduce society’s obsession with garden ‘neatness’?

Yes! It also requires us to hassle our local councils until we outnumber those strange people who complain about overgrown verges. Councils will take the path of least resistance, which should be to do as little ‘tidying’ as possible.

A common threat for several of the species you cover in Black Ops & Beaver Bombing is light pollution. Is there momentum at the moment that would see light pollution effectively combated in the coming years?

No, and the problem is worsened by the fact that lighting is getting cheaper and more intense. It’s frustrating because light is one of the few pollutants that simply disappears as soon as you flick a switch.

In chapter 7, ‘Who Cares What Colour the Squirrels Are?’, you mention that certain conservation strategies, such as the culling of grey squirrels to protect red squirrels, are unlikely to receive funding due to fears of adverse publicity. How much do you think conservation strategies are affected by how palatable they are to the public? Do you think this impacts the effectiveness of some conservation projects?

The biggest issue is the insatiable appetite for novelty over longevity. Nobody wants to fund routine maintenance. You may get grant money to reintroduce water voles, but will you still be funded to cull American mink a decade later?

As storms often lead to the deaths of many seal pups, will the increased occurrence of extreme weather due to climate change have a significant effect on population recruitment for seals on our shores?

We don’t know. In our seal chapter, we call the recovery of grey seals the great mammal conservation story of the twentieth century. Their numbers increased from about 500 during the First World War to well over 100,000, which makes up around 40% of the global population for the species. Storms and tidal surges can wipe out entire colonies of pups in any given season, but thankfully so far that doesn’t seem to have dented their population growth. Shout out to the amazing volunteers who rescue and raise pups for 6 months before they’re strong enough to be released!

The government recently released England’s first Marine and Coastal Wildlife Code, do you think this guidance will significantly help to protect wildlife such as grey and harbour seals from the impacts of visitors? 

Yes. It was long overdue, and it’s vital. Some people will remember seeing the footage of a runner deliberately chasing a colony of seals into the sea in Yorkshire. If that happens to a moulting seal or a pup, they can die. We’re all tempted to take selfies next to wildlife, but it’s rarely a good idea.

This book ends by asking why Britain cannot seem to accept mammalian predators in the way that European countries have. Do you think there is hope for change in attitudes that could see the re-introduction of species such as lynx, wolves and bears within the coming decades?

We end the book in the Abruzzo National Park, 90 minutes drive from Rome, where there are now about 11 active wolf packs and 50 bears. The Cairngorms is ten times bigger, and has roughly the same human population. So much for the argument that we’re a crowded island! So we could and should reintroduce these apex predators, but we have to deal with misinformation from (for example) the current President of the National Farmers’ Union, who claims that lynx would pose a threat to ramblers. No wild lynx has ever attacked a human. Cattle, on the other hand, kill 8-10 people a year in Britain.

Do you have any future plans that you could tell us about?

We’ve just started a podcast, ‘Mammals R Us’ (https://rss.com/podcasts/mammalsrus/). We have very different working habits, so our big question is: can we finish another book without getting divorced?

Author interview with Lee Raye: The Atlas of Early Modern Wildlife

The Atlas of Early Modern Wildlife is a ground-breaking volume compiling the observations of early modern amateur naturalists, travellers and local historians for the first time. Drawing on over 10,000 records, this book looks at the early modern state of wildlife in Britain and Ireland, the era before climate change, before the intensification of agriculture, before even the Industrial Revolution. The book presents maps and notes on the former distribution of 153 species, providing a new baseline against which to discuss subsequent declines and extinctions, expansions and introductions. This remarkable resource will be of great value to conservationists, archaeologists, historians and anyone with an interest in the natural heritage of Britain and Ireland.

Lee Raye is an associate lecturer at the Open University and a Fellow of the Linnaean Society, specialising in the history of wild animals and plants in pre-industrial Britan and Ireland. We were lucky enough to have the opportunity to speak with them about what inspired them to write this atlas, what the most difficult aspect of creating this book was, what their future plans were and much more.


What inspired you to write this atlas?  

Several years ago I worked for the RSPB. I went on a weekend induction to The Lodge in Sandy, Bedfordshire, and had a walk around with the reserve archaeologist. He explained that, although it was simple enough to know which animals had declined and gone extinct in the historical period, there was a lack of clarity about how and when this happened. I realised that I already had some of the answers he needed. Around that same time, as a research project, I was translating and analysing the records of wild animals and plants from a single 17th-century natural history book, Robert Sibbald’s Scotia Illustrata (1684). That source is really valuable because it was contributed to by so many people and contains so many important records. For example, there are records of the Great Auk, the Bustard and the Angel Shark amongst the animals and Darnel, Shepherd’s Needle, and Greater Water-parsnip amongst the plants. While doing this project, I started making a list of other comparable texts from the same time period, and to my surprise I realised there was a whole understudied genre of them! I realised that if I combined all of these sources together I could give a decent estimate of the distribution of species in the 16th-18th centuries.

Do you think it’s possible for us to restore our wildlife to the condition it was in early modern Britain or has our landscape changed too drastically? 

When we are doing conservation work it’s really important that we have a strong baseline to work against, otherwise we don’t know when we are restoring biodiversity and when we are just adding species to an environment. I think the early modern period is a good choice of baseline for two reasons. First, it comes before some of the most alarming declines in biodiversity which followed trends like the industrial revolution, the 20th century agricultural revolution, and the gamekeeper culls of raptors and mammalian predators of the nineteenth and early 20th century. But it was still a period when all of Britain and Ireland was managed for human needs, including some big cities. Secondly, there are a lot of sources available from the time period, so the Atlas of Early Modern Wildlife could reconstruct the fauna found at the time. But we are never going to be able to perfectly return to that baseline. The islands of Britain and Ireland are even more intensively managed and exploited now, and we need to keep that up to provide for the human population. The early modern period was also a time when there was a temporary climate change, the Little Ice Age, which meant that the so-called ‘northern species’ were doing really well, and the ‘southern species’ had a more restricted range. Modern global heating is going to become much more severe than the Little Ice Age was, and is likely to magnify the differences so that Britain and Ireland in the 21st century is going to have significant differences in its flora and fauna to the 17th century, no matter what we do. 

The distribution trend for the majority of species mentioned in this book was either uncertain or unchanged, compared to 24 increases and 26 decreases. Did this surprise you? 

I knew that there would be lots of uncertainty in the data from the time period, but I was a bit surprised that so few species showed a decline in distribution. We know that we are in a biodiversity crisis now, but the declines in abundance we are currently facing are going to take some time to result in declines in distribution at a regional level, which is the rather crude metric I was able to track in the Atlas of Early Modern Wildlife. It’s also true that there have been official and unofficial reintroductions in the modern period, which have restored species like Beaver, Otter and Greylag Goose across much of their early modern range, meaning that comparing early modern and present distribution hides what happened to these species in between. 

Greylag goose by ianpreston via Flickr

You mention that there was a bias towards recording exploitable species in the early modern period and a bias towards recording birds now. Did this affect which species you were able to include in this book? 

Yes, with the exception of a few species of conservation concern, I included only the best-recorded species in my Atlas of Early Modern Wildlife. That means that there is a bias towards certain groups of species. For example, I was able to map the past distribution of 18 freshwater fishes but only five small songbirds. Don’t ask me about the distribution of the Sparrow or the Great Tit in the early modern period, because my sources don’t offer much data about them! 

What was the most difficult aspect of creating this book? 

The most complicated part of the Atlas of Early Modern Wildlife has been trying to solve the recorder-effort problem. I needed to be able to tell when species were not recorded because they were absent (like the Wolf, which seems to have been extinct in England and Wales already by this time period), and when animals were not recorded simply because not enough effort had been put into recording them (like those Sparrows and Great Tits which no-one really cared about). My solution was to statistically compare how many records I had for each species from different regions of Britain and Ireland with a figure of how well-recorded each different region was in the early modern period. I also used some habitat suitability modelling to try and establish patterns behind absences, but this has been complicated, speculative work! 

Do you have any future plans that you can tell us about? 

I think I could take this project further in the future. It should be possible to map the distribution of wild plants 250-500 years ago, or to join up the distribution of Britain and Ireland’s wildlife with the distribution of wildlife in other parts of Europe from the same time period. But I also want to work a bit more on poetry from the early modern period. There are a few very strange poems written c.1580-1650 that protest environmental destruction and are told from the perspective of animals which I think deserve to be much more widely known. 


The Atlas of Early Modern Wildlife by Lee Raye is due to be published by Pelagic Publishing in July 2023 and is available for pre-order from nhbs.com.

Author interview with Tim Blackburn: The Jewel Box

Interwoven throughout with tales of his experiences moth trapping on his London rooftop and in the Devon countryside, The Jewel Box by Tim Blackburn introduces us to a range of ecological theories and explains some of the where, why and hows that anyone curious about the natural world might tend to ponder upon. Beautifully and engagingly written, it manages to be both an ode to both the moths themselves and the activity of moth trapping, as well as a wider ranging exploration of the relationships between humans, other species and habitats.

Professor Tim Blackburn is a scientist with thirty years of experience studying questions about the distribution, abundance and diversity of species in ecological assemblages. He is currently a Professor of Invasion Biology at University College London, where his work focuses on alien species. Before that, he was the Director of the Institute of Zoology, the research arm of the Zoological Society of London.

In this Q&A we chatted with Tim about The Jewel Box as well as about moths in the UK, the things we still have to learn about them, and the species that he’s hoping to see in the flesh.


What struck me most about your book was how you manage to write about complex ecological theories in a very accessible way, while at the same time conveying your very personal admiration and fascination for these insects. What was it that convinced you that this book in particular needed writing?

For a few years now I’d wanted to write a book that presented the natural world in the way that ecological scientists tend to think about it. There is a lot of very fine writing about nature, but most of it is more natural history than science, or is very much focused on a specific organism or location. While The Jewel Box does use moths to illuminate and illustrate the rules that we (ecological scientists) think underpin how nature works, it is very much about those rules, rather than the moths themselves. I’m very happy to hear that you thought I explained the science in an accessible way – that was my fundamental goal.

Within the UK, we have a rich history of recording and studying moths. Where do you think are the big gaps currently in the research? Are there things about moths that we still know little about?

There are still lots of gaps in our knowledge of UK moths – hardly surprising given that we have 2,500 or so species here. For some, we still don’t know their natural food plant. For others, we don’t know if they still exist here. In this latter regard, it seems incredible to me that we are still arguing about the scale of insect declines in the UK, and what the causes of those declines are. We think moth numbers have probably dropped by 30% since 1970, but that information is only available for the commoner species of larger moths, and may be biased in various ways. While we have a rich history of moth recording, and some good data for moth population changes, we could really do with more.

Why do you think it can be so addictive to observe, identify and list the species that we find, whether it’s birds, plants or moths?

I don’t know! For me, it’s pretty much a hard-wired instinct. My mother says I was pointing at birds before I could talk. I’ve been a birder all my life. More generally, there is something deeply satisfying about observing and identifying species – a series of puzzles to work out. Yet unlike most puzzles, the solution is not a product of the human mind, but something more profound. It’s the start of an exploration into understanding millions of years of evolution and ecology. I love a cryptic crossword, but identifying moths gives me so much more joy.

As someone who was trapping before, during and after the Covid restrictions, did you observe any significant differences in the numbers or species of moths that were attracted to your trap during the periods of lockdown?

I wouldn’t say I noticed obvious differences due to lockdowns, although the first lockdown period itself was a very productive one for my moth trap. That was because I was in the Devon countryside when lockdown happened, rather than my upstairs London flat. The countryside is so much better for moths (numbers of species and individuals) than the city, and that spring was notably warm and sunny, which the moths loved. The 2020 lockdown was my most intensive period of trapping to date.

We are generally well informed about planting wildflowers for pollinators such as bees and butterflies and providing food for our garden birds. But what can we do to encourage moths?

The same really! Butterflies are just showy, diurnal moths. Moths are as good pollinators as bees, and like flowers and pollen just as much. So anything you do for the butterflies and bees will likely help the moths too. You just won’t see the impact as obviously, because most of the moths are using your garden while you’re sleeping.

Are there any species that you’ve yet to trap but are on your mothing ‘bucket list’ so to speak?

In The Jewel Box, I spoke about dreaming of catching a Death’s-head Hawk-moth, one of the largest and most iconic British moth species. Last October, I opened my moth trap on Blakeney Point in Norfolk to see that that dream had come true. It’s a moment that will stay with me forever. Now, Oleander Hawk-moth– the species that inspired the book’s cover – would be the dream, albeit even less likely than catching the Death’s-head.

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

I’m mulling on the next book, but still enjoying all that’s new and interesting in my life as a result of publishing The Jewel Box. But watch this space…

Author interview: An Identification Guide to Garden Birds of Britain and North-West Europe

An Identification Guide to Garden Birds of Britain and North-West Europe is a photographic guide to 75 species of bird most commonly found in or over the gardens of Britain and North-West Europe. The text combines scientific facts with affectionate descriptions of the birds’ identifying features, including sex and age differences, habits, nest types, eggs and calls. The introduction contains tips on how to identify birds, how to look after garden birds, which species can be seen throughout the year, a glossary and anatomy details. For each species, there are two or three photographs labelled with distinguishing features where appropriate, a calendar showing the time of year when the adult can be seen and star facts that give further proof of the birds’ fascinating features.

Dominic Couzens

Dominic Couzens is an award-winning nature writer with 40 books and hundreds of published articles to his name. His best-known books include An Identification Guide to Garden Insects of Britain and North-West Europe, The Secret Lives of Garden Birds, Britain’s Mammals (WildGuides) and Save Our Species. Carl Bovis is a nature photographer with a particular passion for birds. The advent of digital photography has given him the opportunity to capture the birds he sees and share them with the world.

We were lucky enough to ask both Dominic and Carl a few questions about what inspired them to produce this guide, what the process was like to assemble it and the importance of providing habitats for birds in our gardens.


What inspired you to produce this introductory guide to garden birds?

Dominic: As a regular Twitter follower I quickly became aware of Carl’s work. What stood out for me was his wonderfully giving attitude, really helping “ordinary” people connect with birds and birdwatching with the use of clever and funny bird photos, as well as wondrous ones. He encourages everyone to get involved and to enjoy nature, and he does it in a unique way.

So from my (Dominic’s) point of view, it was a no-brainer to cooperate with Carl on an entry-level guide to garden birds, with his own special take.

This book follows on from a book on garden insects published with another first-time author, Gail Ashton, last year. In both guides we have used light-hearted introductions and mentioned star facts about each species, to helve delve into the subject’s life.

How did you choose which species to include in this guide?

Our subject was garden birds, and since we wanted to cover northern Europe we had a good range to choose from. Most species pick themselves, but the guide will stand or fall on what we include.

This guide is full of many wonderful and illustrative photographs. What was the process like to assemble these? Where there any species that were particularly difficult to attain clear photos of?

Carl Bovis

Carl: I’m known for taking photos of the common birds, a lot of which many serious bird photographers turn their noses up at! So a book about garden birds was perfect for me, as I have taken many photos of them over the last few years and had many to choose from. I also have a passion for catching birds in flight, the shape and angles of their wings and tail fascinate me. Obviously this is an ID book, so perched birds are essential, but we’ve included lots of flight shots too.

It’s very rewarding for me to have my photos in this guide. A couple of years ago I was talking to a serious birder at Steart Marshes and he said to me; ‘your photos of birds are very engaging, but they’d never be in a mainstream bird book’. I didn’t take offence, I like that many of my photos are different to the norm, but at the same time, I’m happy now to have proved him wrong!

It’s also an honour to collaborate with Dominic on this, as before I even knew him personally, I had bought and enjoyed many of his previous books, and had attended one of his fascinating talks on bird behaviour. He is nature-writing ‘royalty’ as far as I’m concerned.

The shy and rarer garden birds were obviously toughest to get clear photos of, especially ones that don’t visit my own little Somerset garden where many of the photos were taken. So birds like Bullfinch, Treecreeper and Redstart were a challenge. If you get them in your garden, consider yourself lucky!

Included with this interview are a few of my favourite photos from the book.

Given the many pressures facing our garden birds, are there any species in this guide that you think won’t be so common in coming years?

Dominic: We have included a number that are declining, such as Marsh and Willow Tits, Chaffinches and Greenfinches. The Lesser Spotted Woodpecker is in serious trouble, and both House Martins and Swifts are on the wane. There are others, too.

But I do think it’s very important to let people just discover and enjoy birds. I hope the book inspires first and foremost.

This guide includes a section on looking after garden birds, giving tips as to how people with gardens can help. How important is it that people make their gardens into good habitats for birds?

Dominic: Gardens are incredibly important for two reasons. They are the best place for people and birds to meet, and for people to get excited about birds and love them.

Secondly, gardens are where everybody can be a conservationist. The overall fortunes of birds and other wildlife often feel as though they are outside our control, but in gardens we can make decisions that directly affect wildlife. If enough people realised how important their backyard decisions were to wildlife, they might be inspired to do more.

Are there any plans to continue this series and, if so, which other species groups that you would like to make an identification guide about?

Dominic: Yes, a book on Trees is already well in production. Any others in the series may require us to get John Beaufoy, our publisher, drunk so that we can persuade him to do some more.


An Identification Guide to Garden Birds of Britain and North-West Europe by Dominic Couzens and Carl Bovis is published by John Beaufoy Publishing in June 2023 and is available from nhbs.com.

Author interview with C. Philip Wheater and Helen Read: Animals Under Logs and Stones

Logs, stones and the like provide an interesting interface between the damp depths of the soil and the drier open ground surface, offering refuges for a fascinating array of animals. The communities of organisms that live beneath them are little noticed and even less studied, yet the potential for ecological work here is great. Animals Under Logs and Stones is number 22 in the popular Naturalists’ Handbook series and is a greatly expanded and updated version of the first edition which was published 27 years ago. It provides comprehensive information about these unique habitats and includes a range of easy-to-use and illustrated identification keys to help both amateur and experienced naturalists identify their findings.

Philip Wheater is Professor Emeritus of the School of Science and the Environment, at Manchester Metropolitan University. His interests include ecology and management of human-influenced environments, especially urban systems; invertebrate conservation and management; access to, provision and assessment of environmental education; environmental monitoring, especially fieldwork and the use of statistics.

Helen Read is a Conservation Officer for the City of London Corporation based at Burnham Beeches, a post held for over 30 years. She has written numerous books and papers on a variety of subjects, the majority being on the management of veteran trees and topics relating to invertebrates. She has also been an active committee member in various invertebrate societies.

With the upcoming publication of Animals Under Logs and Stones, we were fortunate to chat with Philip and Helen about the book and about the importance of these unique habitats in supporting a range of invertebrates and larger animals through various stages of their life histories.


The first edition of Animals Under Logs and Stones was published 27 years ago. What inspired you to write the second edition, and what do you think are the key things that have changed during this time in terms of our knowledge and research techniques?

There have been many changes in taxonomy over the last few decades, not least because of major advances due to the use of molecular techniques more recently. Also, more information is now available on the distribution of many species that are found under logs and stones. Because of increased interest in many of the groups found under logs and stones, it is now possible to expand the range of the book from the original 17 identification keys to 25 in the new edition. With modern publishing techniques we are now able to include many photographs to illustrate both the species and habitats covered by the book.

What benefits do the cryptozoan communities living under logs and stones bestow on their surrounding ecosystems?

Soil and leaf litter dwelling communities are important in decomposition, nutrient cycling, and soil formation and maintenance. In addition to logs and stones being microhabitats where some species live, others that can be found in soil and leaf litter use them as refuges. And it is possible to find many of these animals more easily than it would be by searching within the soil and leaf litter layers.

As children we’re fascinated by turning over rocks and seeing what’s underneath. Then, for the most part, we grow up and become increasingly distracted by other pursuits. Why do you think it is important that we value these often-overlooked microhabitats and ensure that they are explored and studied.

Even though many of the animals found under logs and stones are rather small and may not be quite as showy as butterflies or dragonflies, they are fascinating in their own right. Many of these animals may be found at times of the year when other invertebrates (especially flying insects) are not present. They are also not restricted to special sites; a wide range of species can be found in anyone’s back garden and observed without the need for specialist equipment. In addition, their ecology and life histories are generally less well known to the general public and can be very interesting to study.

In our modern world where there is often the pressure to make everything social media-worthy and aesthetically pleasing, it is easy to become obsessed with tidiness, both in our gardens and in other wild spaces. How important do you think it is that management strategies recognise the benefits of dead wood and stones which might otherwise be seen as unnecessary debris?

Leaving logs and stones in situ is increasingly acknowledged as being important to provide a wider range of refuges for animals. These days this is even the case in quite formal parks and gardens. There is a wider understanding of the reasons for more natural approaches to the management for wildlife. Similar initiatives such as No Mow May are spreading the concept of naturalistic management to a wider audience. Environmental interpretation and education will be key to continuing to spread this message.

As with all the fantastic Naturalists’ Handbooks you provide lots of information on designing and undertaking research projects as well as analysing and presenting the final data. For any enthusiastic naturalists who are not currently in education or working in a research environment, is it still of benefit for them to record their findings? And how could their records add to the general body of knowledge about these animals and habitats?

All well thought out studies can provide useful and interesting information, especially where there is little current knowledge about particular species and their natural history. Anyone can contribute records through apps such as iRecord and iNaturalist. Even information about relatively common species can be useful in looking at changes in distribution due to environmental change such as climate change. Those with a particular interest in a specific group of species can find like-minded people who organise field days, collate information and publish (often on-line) records and ecological information. Often species recording schemes or wildlife trusts are a good place to start. Our book lists many places where people can get more information about such groups.

Finally, what’s next for both of you? Any more books in the pipeline?

We are currently working together again on a book, to be published by Pelagic, on the ecology and management of Burnham Beeches which is a National Nature Reserve and a Special Area of Conservation in South Bucks. This will cover the range of plants and animals found at this important nature reserve, together with background on the history and management of an area that was set up as one of the first “green lungs” of London to provide a public open space. Helen is also finishing an update to the Synopsis of the British Fauna on millipedes for the Linnean Society with her colleague, Paul Lee.


Animals Under Logs and Stones by C. Philip Wheater, Helen J. Read and Charlotte E. Wheater is published by Pelagic Publishing in July 2023 and is available from nhbs.com.
