Climate Challenges: 1. Insect Decline

In the lead up to the 26th UN Climate Change Conference of the Parties (COP26) in November of this year, we are writing a series of articles looking at some of the toughest global climate crisis challenges that we are currently facing. This post looks at the evidence for and challenges posed by a global decline in insects.

What is the evidence for a global insect armageddon?

One of the first meta-analyses of insect population decline was published in 2014 by Dirzo et al. in Science under the title ‘Defaunation in the Anthropocene’. This seminal paper reported that 67% of monitored invertebrate populations showed 45% mean abundance decline and warned that ‘such animal declines will cascade onto ecosystem functioning and human well-being’. Three years later, Hallmann et al. (2017) published the results from 27 years of malaise trap monitoring in 63 natural protection areas in Germany, and concluded that insect biomass had declined by more than 75% during this time. This paper in particular was widely reported in the media, creating widespread concern among the public of an impending insect armageddon, or ‘insectageddon’.

Since then, several other reports have continued to draw attention to declines in insect abundance, biomass and diversity around the world (for excellent reviews see Wagner (2020) and Sánchez-Bayo & Wyckhuys (2019)). However, many of these studies have been restricted to well-populated areas of the US and Europe and there is little information available to assess how these patterns compare with other less well studied regions.

Despite the abundance of data suggesting a pattern of global insect decline, many studies show conflicting results, with datasets from a similar area often reporting different patterns. There is also evidence that some insects are faring well, particularly in temperate areas which are now experiencing milder winters. Species that benefit from an association with humans, such as the European honeybee, may also be experiencing an advantage, along with certain freshwater insects that have benefited from efforts to reduce pollution in inland water bodies.

What are the challenges in assessing and predicting insect population trends?

In comparison to vertebrate groups, comprehensive long-term datasets are rare for invertebrates. This is primarily down to the fact that invertebrates are incredibly species rich and so, even for those that have been formally identified and described, a considerable amount of skill and knowledge is required for reliable identification. In addition to this high level of expertise is the need for large amounts of field equipment, which means that long-term, comprehensive studies can be expensive and difficult to fund.

Both historical and current invertebrate monitoring data tends to come from a small number of wealthy and well-populated countries (usually the US and western Europe), and there are comparatively few datasets available from tropical and less developed areas. Unfortunately, these understudied countries and regions tend to be the areas where we might expect to find the most diverse and species rich populations of invertebrates.

Other challenges relate to the way that data is collected. Using total insect biomass as a measure provides a useful large-scale perspective and provides information relevant to ecosystem function. It also minimises the problems involved with taxonomy and identification. However, using this measure means that species-level trends are completely overlooked.

What are the main stressors affecting insect populations globally?

Studies suggest that the main stressors impacting invertebrates are changes in land-use (particularly deforestation), climate change, agriculture, introduced and invasive species, and increased nitrification and pollution. However, it is rare that a single factor is found to be responsible for monitored declines and the situation has been described as being akin to ‘death by a thousand cuts’.

In a recent special edition of PNAS, that looked in depth at the available research and literature on insect decline in the Anthropocene, climate change, habitat loss/degradation and agriculture emerged as the three most important stressors.

Where do we go from here?

Traditionally, conservation has focused on rare and endangered species. However, with mass extinctions and large scale invertebrate loss, which include declines in formerly abundant species, a different approach is required. Invertebrates form an important link between primary producers and the rest of the food chain, and play a key role in most ecosystems. They provide numerous ecosystem services such as pollination, weed and pest control, decomposition, soil formation and water purification, and so their fate is of both environmental and economic importance.

There are several things to be positive about within the realms of invertebrate conservation: over the past decade, funding to support insect conservation has been growing and, in many countries, there are now substantial grants allocated to monitoring and mitigation projects. The EU and US have seen widescale banning of certain pesticides following research demonstrating their impacts on both economically important pollinators and other fauna. Finally, citizen science projects to study invertebrate populations are becoming both numerous and successful, greatly increasing the amount of comprehensive, long-term data that is available to inform conservation decisions.

Despite this, much more long-term data on invertebrate populations is required, particularly from regions outside of Europe and the US, such as tropical areas of the Americas, Africa and Asia. Attention to factors such as the standardisation of survey techniques and improved data storage and accessibility are also important, as well as the utilisation of new methods including automated sampling/counting equipment and molecular techniques. Using the information available, evidence-based plans for mitigating and reversing declines are desperately required.

All of this takes time however, and we need to act now. Even without comprehensive species-level data, we know that a biodiversity crisis is occurring at a rate serious enough for it to have been termed the ‘6th Mass Extinction’. Individual, group, nationwide and global action will all be required to combat this. Widescale change in societal attitudes to insects will undoubtedly need to play a role in this process, alongside global efforts to slow climate change and develop insect-friendly methods of agriculture.

Summary

• Numerous studies have reported large-scale declines in insect populations, with several estimating a loss of approximately 1–2% of species each year.
• The availability of high-quality and long-term datasets is a limiting factor in assessing population trends. Furthermore, available data tends to be from well-populated and historically wealthy areas such as the US and western Europe, with the diverse and species-rich tropics severely under-researched.
• The main stressors thought to be impacting insect populations globally are climate change, habitat loss/degradation and agriculture. In most, if not all of these cases, a combination of these and other factors are likely to play a role.
• Although there are some aspects of insect conservation to be positive about, much work still needs to be done. Further monitoring and recording are required, particularly in poorly studies areas, in order to inform conservation decisions. Simultaneously, local and global efforts must be made to slow climate change, halt the destruction of ecologically important habitats and develop nature-compatible methods of agriculture.

Thermal Imaging For Ecologists

In the new Summer 2021 issue of Conservation Land Management magazine (CLM) Dan Brown, ecologist and founder of Wild Discovery, provides an overview of thermal imaging technology and how it can be applied in wildlife surveys. Here you can read a summary of the article.

Thermal imaging was originally developed for military purposes but has since been deployed in a variety of fields, including increasingly so in conservation and ecology. It works by using medium- and long-wave infrared radiation to create a heat image called a thermogram – the varying temperatures can be displayed either as different colours, shades or as a monochromatic image. In light of its growing popularity in ecology, this article discusses how this technology can be used in wildlife surveys and what needs to be considered when doing so.

Field applications

One important benefit of using thermal imaging is that species that are usually difficult to survey, particularly cryptic or nocturnal species, can be readily detected. Ptarmigan, for example, can be tricky to spot in scree and boulder fields, and so the use of thermal imaging can be an efficient way to monitor an elusive species such as this with greater accuracy. Also, as this is a non-invasive surveying technique, the behaviour of wildlife can be observed with little disturbance.

Thermal-imaging technology has already been trialled in surveys of a number of different species. In the Forest of Dean, for example, the Forestry Commission uses thermal imaging to monitor wild boar, and the Mid Wales Squirrel Partnership uses it to monitor active red squirrel dreys. This technology can also complement acoustic monitoring for bat surveys – the species of bat can be determined using a bat detector, while thermal imaging can help to identify potential roost sites and enables the surveyor to count the number of individuals present.

Another advantage of thermal-imaging technology is that it works both during the day and at night. Studies of woodcock and nightjar have put this to good use – researchers have been able to locate day-roosting birds and also monitor their nocturnal activity, such as foraging behaviours and flight patterns, with minimal disturbance to the birds.

Potential for other uses in the field

But what else can thermal imaging be used for in species monitoring? Elsewhere in the world, thermal-imaging systems have been fitted to farm machinery to help detect ground-nesting bird species, a method that could be applied in the UK to monitor curlew, lapwing and stone-curlew. Similarly, attaching thermal-imaging equipment to drones could provide an opportunity to survey inaccessible species and areas.

And it doesn’t have to be just warm-blooded animals either. There is huge variation in heat signatures across the landscape, even between different tree species, and so using thermal imaging could aid searches for potential locations for roosting owls, for example, or help to identify possible basking spots for invertebrates and reptiles. There is also potential for this technology to be used to search for insects that display a distinct heat signature in low ambient temperatures, such as queen wasps and bumblebees or larger moths.

Considerations and limitations

When planning and designing surveys and fieldwork, there are a number of factors that need to be considered when using thermal imaging. For instance, its effectiveness can differ depending on the season or weather – the heat signatures of birds and mammals can be masked on sunny days, whereas these signatures are more detectable during overcast days when the ambient temperature is lower. In order to use this equipment effectively, adequate practice and training is required and although there are some training courses available, there is not a huge amount of published guidance on using thermal imaging for wildlife surveys. And even before choosing a thermal imaging scope, it is important to consider its intended use, its detection distance (as this varies between different models), and cost.

In the full article Dan Brown describes how thermal technology works, provides more detail on how thermal imaging can be applied to wildlife surveys and the benefits of doing so, and describes the resources and training that are currently available for ecologists using thermal imaging.

Beaver Trust: Q&A with Eva Bishop

Eva Bishop

Eva Bishop, Communications Director for Beaver Trust, recently took the time to talk to us about the important work the charity is doing to help communities welcome beavers back to Britain.

In this thought-provoking conversation, we discuss some of Beaver Trust’s upcoming projects, how the Covid pandemic has affected them as a charity, and share different ways to get involved in beaver conservation within Britain.


1. Firstly, can you tell our readers a bit about the Beaver Trust and its main aims?

Our overall mission is to restore Britain’s rivers and wildlife with beavers. We were not in fact established as a single species charity, but as a small crew wanting to build climate resilience for people and wildlife – yet we see the potential for rapid and restorative action that beavers offer. If you take a look at a map of British waterways it depicts an expansive system of veins carrying the lifeblood of the country. Then imagine huge swathes of that being given greater space for nature, becoming living wetlands and water storage systems rather than drained, polluted, straightened ditches. Beavers are our ally here so we are working collaboratively with a range of organisations and of course landowners to support their return.

Beaver Trust’s core work involves convening real conversations in order to make good decisions on national beaver policy and a supporting management framework, finding engaging ways to achieve outreach and education on learning to co-exist with beavers again, and of course supporting many beaver projects on the ground. Our national aim must be to move beyond enclosed projects wherever possible so that beavers can once again become part of native wildlife fauna and work across whole catchments to reinstate biodiversity and healthy ecosystem function.

2. There is a lot of contention between some landowners and conservationists around the subject of beavers, particularly when it comes to reintroductions. Do you find that misinformation and prejudice are significant challenges in the case of this species?

Where misinformation and prejudice exist it’s always unhelpful. However, I think the existence of conflict can be overplayed with beavers and our experience has been one largely of cooperation and collaboration.

Beavers and their impacts aren’t always beneficial to the surrounding land use, we’re very clear about that. Where contention does arise it can often be overcome through better information and knowledge. Well practiced management techniques are being successfully used across Britain, with the right experience and resources there is no reason for these not to become second nature like tree protection against deer for example. Beavers are reestablishing already, but we have an opportunity to target areas for new wild releases that are less likely to cause conflict and instead achieve greater benefits for society and wildlife. That’s something we are collectively all working towards, to minimise conflict.

There is always room for misinformation – hence our core strand of work around communications and education – and there is still work to be done engaging a broad audience in key conversations around beavers (such as farming, angling, flood-banks and the appropriate use of lethal control), ensuring broad diversity in all conversations and that everyone is heard. There is a lot of good research available on the impacts and effects of beaver reintroduction across Europe, not to mention the research within Britain as well. Management is also well-established and now requires government resources to expand nationally alongside training and communications, so that we can offer a swift response to any anticipated, perceived or felt issue.

Prejudice is harder to tackle, as is human nature’s aversion to change, but we always aim to put forward a transparent view of beaver impacts including challenges and invite inclusive debate across our work. But as I said, Beaver Trust’s experience in England to date has been a pretty positive one with the landowning and farming community.

3. A core component of your work moving forward is set to focus on river buffer zones – allowing nature to recover and regenerate around river banks. Can you tell us more about this?

Yes, and it links directly to the previous question. If we want beavers to achieve all the good flood and drought mitigation, water filtering and biodiverse habitat restoration we anticipate, they will need space to operate. Their dams and canals can revert streams and smaller rivers into meandering wetlands, however, depending on the location this could quickly cause issues. In a sense, we need to make our rivers fit for beavers (and all other life that should exist there), without placing further burden on farmers trying to do the right thing and produce affordable food.

The key is space for nature. Stepping back from the margins and allowing the naturally high biodiversity that should exist there to thrive. Beaver Trust is therefore working in partnership with leading environmental NGOs on a programme for riparian buffer zones along whole catchments. We need a greater vision than a small strip of river bank, and are aiming for 10-20m+ zones, but it could even mean whole floodplains are set aside for natural processes.

Farmers will then be paid for nature’s recovery and we’d like to see farm clusters able to apply, allowing greater scope for whole catchment restoration and connected nature corridors. For the programme to succeed and feed into ELMs we need a simple payment mechanism and not just another layer to add to the farmer’s list of environmental expectations. We need a broad partnership, including Defra, to think systemically so that it becomes easier for land managers to make good environmental decisions without hidden costs to their operations.

If we allow rivers the space to find their natural course and re-establish meanders, scrub and woodland to naturally regenerate, beavers to bring back freshwater habitat and increase species abundance, then we will start to see real resilience along our river network ready to help us as climate pressures hit harder and stronger.

We hope to see a bold and ambitious government strategy for beavers, but given their catchment-scale impacts we should be thinking systemically with related policies. The great thing about river buffers is that it could take relatively little land out of production – but these edges are where all the great biodiversity happens. So it’s a win-win for conservation and farming if we make it easier and practical to sign up.

4. Are there any other big projects that the Trust is going to be working on in the near future?

Our main policy campaign this year will be river buffers, working in partnership with the National Trust, Rivers Trust and Woodland Trust. As part of this we are working on a follow-up documentary film to the award-winning ‘Beavers Without Borders’ (2020) that explores the challenges and opportunities for river buffers, interviewing experts on a variety of areas including farming, angling, public access and biodiversity. But we will also continue our core policy ambition convening broad stakeholder working groups on the English Beaver Strategy, which the government is set to consult on this summer.

In the restoration department we are supporting a groundbreaking community-led beaver project where a group of local landowners and residents are looking to reintroduce beavers as a flood mitigation strategy along the whole catchment.

Beaver Trust has also recently been awarded the call off contract for the beaver management framework in Scotland by NatureScot, so we’ll be gearing up for a busy season at the end of the year. Working alongside landowners experiencing conflicts particularly in prime agricultural areas and looking towards long-term mitigation strategies. This can range from ecological advice, tree protection, dam and burrowing mitigation, to translocation as a last resort. In collaboration with the animal care and veterinary team at Five Sisters Zoo, beavers are health screened and rehomed to licenced projects elsewhere in the country.

Our communications and outreach team is working hard across a number of projects, including The Lodge Cast podcast series, radio and other media. We also have several education initiatives under way but one particularly exciting partnership is for a new beaver enclosure and educational learning hub at a major tourist attraction in the South West. The key driver of this project is improving nature connection with children from socially and economically deprived backgrounds, and people with reduced mobility and sensory and cognitive disabilities. We have not yet secured funding for this project so cannot say further than that at present but it exemplifies Beaver Trust’s ambition to educate and connect people beyond wildlife enthusiasts with the joys that beaver wetlands offer.

5. The Covid pandemic has had a huge impact on individuals and organisations. How has the Beaver Trust been affected over the past year, and how have you dealt with these unforeseen challenges?

It’s been a genuinely interesting and challenging time to be part of a new charity: Lockdown arrived while Beaver Trust was really getting its roots down, there was no furlough option for us at the time as we were so new, plus we were a very small team and some of us had the challenge of home education to navigate (torturous for both teacher and pupil)!

But it has made us a really strong and resilient team, given our remote locations. I think one of the great strengths of Beaver Trust people is their wholehearted approach to work: Real conversations, emotional wellbeing and individual authenticity is encouraged and, for us, it works well. It also helped immensely to have a powerful passion for nature restoration and climate action shared within the team, enough to keep everyone motivated, and to have such incredible support for beavers from the public. They are already a much-loved animal and as such we’ve received reams of very humbling offers of voluntary support from all sorts of highly experienced individuals. We are grateful for every single one.

6. Thank you so much for your time in chatting to us. One final question: for anyone interested in getting involved in beaver conservation within Britain, how would you suggest that they go about this?

Beaver dam by Eva Bishop

It’s a great question and I’d start by saying it’s time to break the system: forget career silos, land and wildlife needs ALL of us – it is everyone’s countryside, rivers are everyone’s source of freshwater and wildlife should be part of everyone’s mental health and wellbeing whether through paid employment, voluntary time or new cultural norms. To use a small example, how do we make litter picking fun? Anyone can care for their local patch and help conserve it. I recently saw a wine bottle used in the construction of a beaver dam, something we can avoid by everyone taking part.

But I also think the conservation sector can be quite intimidating and packed with such expertise it’s hard to infiltrate, so I’d encourage people to follow their interest and speak up, even if you’re not sure you tick every box. Within beaver restoration, specific roles will emerge within charities and across communities as wild populations expand, specific training programmes will be available (for example beaver management through CIEEM), keep an eye out for new job opportunities with Beaver Trust, Wildlife Trusts, Woodland Trusts and others.

Another idea would be to join in with some citizen science on collecting information on beavers and river impacts. This doesn’t need to be specific to Beaver Trust either – there’s the Freshwater Habitats Trust, or the Mammal Society which has a mammal tracker app, all of which could help support wider conservation work.

If you’re already in employment, why not talk to your company about funding nature’s restoration and helping scale the impact of nature restoration charities. One of the biggest challenges to conservation is the funding and resources to expand operations.

On a purely fun level, Beaver Trust also hosts regular outreach activities like May’s poetry competition, last year’s photography competition, the monthly podcast, online quizzes and various other celebrations, so please get in touch and join in. Write us a blog and we might be able to publish it on our website. The more these communications are shared, the more people will understand what a beaver is and be accepting of its arrival. Conserving nature as a whole will benefit all the species that rely on it, including humans.


You can find out more about the Beaver Trust from their website and by following them on Facebook and Twitter.

To learn more about the Beaver Trust’s conservation projects, you can read the Introducing: Beaver Trust article included in the Spring 2021 issue of Conservation Land Management magazine. In this article, 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.

 

Author Interview with Jon Dunn: The Glitter in the Green

Jon Dunn is a natural history writer, photographer and wildlife tour leader. He is the author of the fantastic Orchid Summer among other books, and his writing and photographs have been featured in Britain’s Mammals and numerous wildlife magazines and journals.

In his latest book, The Glitter in the Green, Jon documents his expeditions from the farthest reaches of Alaska to the tip of South America in Tierra del Fuego in search of hummingbirds. Weaving history and travel writing together, the book describes the special place hummingbirds have in both mythology and culture, all while addressing not only how hummingbirds have suffered in the past, but the threats they face today. Jon kindly agreed to answer some of our questions below.

When and how did you first discover hummingbirds and what is it that draws you to them?

I’ve got the Natural History Museum in London to thank for planting the seed that was to grow, over the years, into a full-blown hummingbird habit. I was a young kid in the 1980s, taken to London by my mother for a day doing the usual tourist things – she wisely saved a visit to NHM London until later in the day, as she knew once I was in there I wouldn’t want to leave.

Amongst the many exhibits one in particular caught me by surprise – a large glass cabinet filled with hummingbird taxidermy. I know, that’s a bit bleak by the standards of today, but back then all I had eyes for were the shapes, forms and colours of the birds. They were so very different to the birds I was used to seeing in the Somerset countryside around our home. After that, every now and again I’d see footage of hummingbirds on wildlife documentaries, and began to appreciate further just how remarkable they were – what Tim Dee described as ‘strange birds: not quite birds or somehow more than birds, birds 2.0, perhaps’.

As a naturalist and a storyteller, I’m a bit like a bowerbird, drawn to colour. Hummingbirds really have it all going on – their biology is one superlative after another; their plumage is jewel-like; they’re found throughout the Americas in almost every conceivable habitat; and they’ve fascinated mankind from our earliest recorded encounters with them – there’s a rich vein of stories to dig into. 

Were there any particular encounters that stood out for you during your research?

Seeing my first Marvellous Spatuletail caught me by surprise. They’re renowned for their plumage and rarity alike, so I was prepared to feel that cocktail of joy and relief familiar to any birder who’s just caught up with a keenly anticipated species. The reality though far exceeded that – the delicacy of the bird compared to the many other hummingbird species swirling around the clearing in question, those preposterous tail feathers, the culmination of waiting decades to see one… I found that a bird could be literally as well as metaphorically jaw-dropping.

There were plenty of other moments that I’ll hold in my heart, and they don’t all involve the iconic, rare species. One such was watching Golden-tailed Sapphires, a hummingbird that looks as if it’s been dipped in rainbows, feeding in a clearing in the immediate aftermath of a heavy rain shower. As the sun broke through the dripping vegetation and steaming air we were suddenly surrounded by myriad small rainbows through which the birds were flying. That moment was ephemeral, over almost as soon as it began, but it’s etched in my memory forever. 

Hummingbirds have long been venerated and romanticised in art and in your book you talk about the emotive response that hummingbirds elicit in people. Why do you think that this is?

I found myself asking myself that very question as my journey into their world unfolded… Hummingbirds certainly seem to touch something deep inside us. They featured in the mythology of the Aztecs; inspired the most dramatic of all of the immense geoglyphs carved into the desert floor by the Nazca; appear in renowned art and literature; and, to this day, are singled out for particular love by those whose gardens they frequent, people who would not necessarily identify themselves as birders.

I think it’s their character as much as their beauty that has always called to us – many species are confiding, and are happy to feed in close proximity to us. Over millennia we’ve given many animals ample cause to be shy of us – and indeed, down the years we’ve slaughtered hummingbirds in their millions for their feathers, whether they were to feature in Aztec status symbols, Catholic icons or on 19th century hats. Yet despite this, hummingbirds remain unphased by our presence. Perhaps there’s something subconsciously reassuring about that.    

In order to see some species, your expeditions took you to some very remote places. Did this present any challenges?

Inevitably there were some logistical challenges to contend with, not least having to reacquaint myself with horse-riding after a decades-long and deliberate avoidance of it! There were a couple of close encounters with large predators that were, in hindsight, more alarming than they felt at the time – as a naturalist, I was thrilled to get (very) close views of a puma… But perhaps the most challenging moment of all was landing in Bolivia at the very moment the country was taking to the streets to protest the outcome of a recent presidential election. There was an incident at a roadblock manned by armed men that was genuinely scary, with an outcome that hung in the balance for a terrifying instant, and could easily have ended badly.

Hummingbirds face many threats to their existence, including habitat loss, climate-change, deforestation, as you talk about in your book. Post-research, do you feel any optimism for these magnificent creatures?

This is a really difficult question. On the one hand, I learned of examples of conservation where hummingbirds – amongst other species, of course – were the beneficiaries of excellent conservation work at a local level. On the other hand, when you start to take a pragmatic long view of our impact to date on the habitats the birds rely upon across the Americas, it’s hard to remain upbeat. We’ve destroyed so much already, especially in the past century – and with a growing global population, the pressures of economic development are only going to intensify human activity and its impacts.    

I sometimes think there’s almost too much optimism expressed when talking about conservation challenges anywhere in the world – a narrative that suggests “if we only care enough, the [insert iconic species name here] can be saved”. And to a degree, that’s good – we’ve got to have hope, as the alternative is too dreadful to countenance – but given our impact to date, and in an uncertain future where the effects of climate change are still unfolding and will continue for many decades to come, to name just the biggest of the mounting pressures on the natural world, I’m not sure that I do feel terribly optimistic, least of all for those hummingbird species that have very localized populations, or depend upon very specific habitats. They’re undeniably vulnerable. But like Fox Mulder, I want to believe…   

 Do you have any plans for further books?

I do indeed… Having delved into the worlds of two of my personal favourites, terrestrial orchids and hummingbirds, in the last two books, the book I’m currently writing will have a wider focus – exploring the evolving relationship between humanity and the natural world. It’ll be a deep dive into a world of obsession, joy, exploitation and wonder – a place where the truth is stranger than fiction.

Author Interview with Penny Metal: Insectinside

As recently featured on BBC’s Springwatch, Insectinside is a fantastic book featuring hundreds of species of insect that have all been found in Warwick Gardens in Peckham by author, Penny Metal.

With Penny’s incredible photographs and often humorous social commentary, Insectinside is an inspiring look at the diversity you can find just beyond your doorstep, as well as the vital importance of our natural spaces.

Can you tell us about your background and how you came to write this book?

I have a background in graphic design and often work in the area of nature conservation. This means I get to see what projects are happening etc. I work from home and decided to spend my lunch breaks in my local park photographing and surveying insects. I learned about the insects, watched them and counted the sheer number of species, and realised that no one else had actually surveyed a small urban park extensively. The book came about as I wanted to show people what was living in the bushes and to put Peckham on the entomological map!

Insectinside is written from the unique perspective of the insects that dwell in Peckham Park. What inspired you to write this way, rather than in a more traditional prose?

I wanted to try a different way of presenting information that would ‘hook’ people and short stories were the way to go. A lot of people don’t like insects and comparing their lives to ours not only elevates them, it gives the reader another perspective on how wonderful they are, and you can add a bit of humour alongside topics which are happening at the time (gentrification, Brexit etc). I find them fun to write, and am often inspired by how an insect looks or acts and what is going on in the news and try and link the two together. It is a good way to introduce some of the lesser known insects. My strategy appears to have worked!

Do you have any favourite species that you would like to tell us about?

I am a big fan of wasps, especially parasitic wasps. My favourite is the Gasteruption jaculator and watching her squeeze herself into the tiniest beetle holes where the scissor bees nest to lay her eggs is a sight to behold.

Recreational places like parks might not always be considered for their conservation potential. What can you tell us about the significance of parkland in the UK?

I think parks have been overlooked as areas of conservation. They can be large places and they have to work hard – recreation, dog spaces, playgrounds, sports spaces, neat formal areas for aesthetics etc, lighting, and usually open 24 hours – but there is no reason why we can’t include habitats for our wildlife. A simple solution would be to leave areas un-mowed to grow wild. In the parks of my local area in London, large swathes of grasses and flowers have been left to mature and people have been really receptive to it. I think we are finally moving away from the Victorian ideal of neat and tidy!

With an ever-growing population in the UK, parklands are becoming increasingly busier. What do you think we need to do to protect our natural spaces?

Tell people to stop destroying them, and to take their rubbish home! Luckily there is more awareness now about the importance of our natural spaces, though there is a way to go yet to get everyone on board. Personally, I would like for our natural spaces to be so integrated into our lives that we can drop names like ‘nature reserve’ and just appreciate nature for what it is.

The book has a great many beautiful insect photographs, taken by yourself. Do you have any advice for aspiring macro-photographers?

Keep a sharp eye and a steady hand! Watch them to see how they move – for instance dragonflies tend to return to their perch a couple of times before they fly away for good.  And a sunny day with clouds is the best time to photograph flying insects as they stop and have a rest when the sun is hidden.

Conservation Land Management: Summer 2021

Conservation Land Management (CLM) magazine is designed for those involved in managing land for conservation, and is an invaluable source of information on good conservation management practice. Here, Assistant Editor Catherine Mitson provides a summary of the range of articles featured in the new Summer issue.

Monitoring and surveying techniques in conservation and ecology are constantly changing and improving. The use of thermal imaging is one example of a non-invasive method that is becoming a popular choice for those involved in wildlife surveys. Dan Brown, ecologist and founder of Wild Discovery, provides an overview of thermal imaging and the potential for its wider application in species monitoring, surveying and ecological consultancy, while still keeping some of its limitations in mind.

Citizen science also plays an important role in species surveys, and Claire Boothby, Training and Surveys Officer for the Bats in Churches project, describes an opportunity for the public to get involved in bat surveys. Bats can often be found roosting in churches, but due to the open roof structure of many of these buildings, the architecture and items housed inside are susceptible to damage from bat droppings and urine, to the despair of church users. The Bats in Churches project is trialling mitigation measures to enable both humans and bats to use churches harmoniously. This article showcases some churches where these mitigation measures have been implemented successfully and describes how the public can take part in the Bats in Churches Study to improve our current knowledge of how bats use churches.

Also in this issue, James Adler and Steve Proud describe the Pirbright Red Deer Project. The Pirbright Range Danger Area (RDA) in Surrey is one of the most extensive and least disturbed tracts of heathland in southern Britain but as this is an active firing range, traditional means of heathland management are not practical. Instead, red deer have been used for conservation grazing to keep vegetation in check, to the benefit of the rarities found at Pirbright. This article discusses the importance of Pirbright and the development, rationale, and results to date of the Red Deer Project.

Jos Milner takes us north to the Cairngorms National Park where the Our Water Environment project, delivered by the Tomintoul & Glenlivet Landscape Partnership, has set out to restore and enhance the river Avon catchment. Here the river bank has suffered from bank erosion and sedimentation as a result of overgrazing and loss of riparian tree cover. This article explains how green engineering techniques, which use natural materials such as logs or coir matting as a form of bank protection, have been implemented on the River Avon, and how these could provide an opportunity for landscape-scale river restoration.

The final article in the Summer issue looks at how one farmer changed the way he farms to benefit wildlife. Martin Lines is a third-generation farmer and contractor, and with the advice provided by Farm Wildlife, he no longer uses insecticides on his land and has instead shifted to an Integrated Pest Management approach. Kathryn Smith and Martin Lines discuss what this has meant for practical farming operations, and the impact this has had on both crop yields and wildlife.

In this and every issue you can expect to see Briefing, keeping you up to date on the latest training courses, events and publications, and On the ground which provides helpful tips or updates on products relevant to land management.

Other features that regularly appear in CLM include Viewpoint, a similar length to our main articles, but here authors can voice their own views on various conservation issues, 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.

Mammal Society: Q&A with Stephanie Wray

The Mammal Society is a charity dedicated to the research and conservation of Britain’s mammals. By surveying, monitoring, researching, and sharing information about the state of mammals, it contributes to conservation efforts to help maintain these species.

Stephanie Wray

We recently spoke to Stephanie Wray, the new Chair of Mammal Society, who kindly took the time to answer some questions about her background, her ambitions for the charity, and some ways in which you can get involved and support mammal conservation.

 

 


1. First, could you tell us a little bit about the Mammal Society and the important work that it does?

The Mammal Society is a charity which works towards the conservation of British mammals based on sound science. We were started in the 1950s and have always had both a strong academic member base of the ecologists and natural scientists who study our wild mammals, but also a fantastic body of amateur naturalists who are fascinated by mammals and willing to give up their free time to learn more about them and help their conservation in practical ways. Over time our membership has grown to include, for example, ecological consultants who work with protected species, protecting them from development, and many others who just love mammals. Increasingly we are benefiting from support from members of the public who, while they may not be able to devote time to practical projects themselves, care deeply about the British countryside and our iconic mammal species and want to help us to help them. At the moment we are developing exciting projects looking at the conservation of mountain hares, our amazing native hare which turns white in the winter and which may be threatened by climate change, and the harvest mouse, a species of traditional farmland as small as a two-pence piece and increasingly threatened by the way we manage our countryside.

2. From your PhD on brown hares in the 1990’s and a post-doc on Livingstone’s bat on the Comores, to your role as past president of the CIEEM and, most recently, your position as director of Biocensus and founder of specialist consultancy Nature Positive, you’ve had an incredibly fascinating and influential career so far. What attracted you to the position of Chair of the Mammal Society?

I’ve always had a soft spot for the Mammal Society, since my first Mammal Society conference in 1989. It’s where, a couple of years later, I presented my first scientific talk on the results of my PhD research and where I met many other mammal enthusiasts who have remained lifelong friends. Many of the Society’s members, professional and volunteer, have helped me with my research over the years, turning up in fair weather or foul to help me catch and radio-collar mammals to learn more about their habits, collect samples of dropping and other ‘glamorous’ tasks. So I want to be able to give something back, to make sure that the Society continues to grow and acts as an effective, science-backed voice for the conservation of wildlife in the UK. Our members have a huge amount of knowledge and experience and I want to make sure that we can leverage that to have our voices heard and deliver the right outcomes for conservation.

3. Unusually for an ecologist, you also have a Master’s degree in Business Administration. Do you think that marketing, economics, and the social sciences in general have an important role to play in ecology and conservation?

Well, you have done your research – I do indeed! We hear a lot about the bad things that businesses do, but the economic reach, innovation and entrepreneurship of industry can also act as a huge power for good. Businesses are starting to realise that their entire operations depend on biodiversity and that working to protect the natural world is not just a philanthropic exercise, it’s sound business sense. Sometimes how a business affects the environment is very obvious (they may use a lot of water or harvest a wild species) but in many cases it is hidden deep in their supply chains. Let’s say that you are a manufacturer of oat milk. You will have a great narrative around the climate impacts of your product compared to dairy milk, soy and almonds – but what about the biodiversity impacts? If the oats you buy are grown at a factory scale, removing hedges and ploughing up to the field boundaries, with the addition of lots of artificial fertilisers or pesticides, then you will have undone all those climate benefits through your impacts on nature – and the decline in the harvest mouse population would be an indicator of that. Now that is not just a concern to the Mammal Society – it’s a risk to your business in terms of future costs (as the environment becomes more degraded then we lose soil fertility and pollinator species, and yields will fall) in terms of your reputation (we’re drinking oat milk in the first place because we care about the environment) and in terms of your ability to attract investment (the institutional lenders don’t want to be on the wrong side of the next ‘palm oil’ issue). Under that kind of pressure, businesses can be incredibly flexible and develop new approaches, like regenerative farming, which can represent a win-win – a premium product for them, a healthier environment for everyone.

4. Taking on the role of Chair of a charity during a global pandemic must be an exciting yet challenging prospect. What are your hopes and ambitions for the charity over the next few years?

It is certainly an exciting time to take on a new role. Particularly during our first ‘lock down’ in Britain last year I think we all really appreciated our limited time outdoors and took time to enjoy those short nature ‘snacks’. For some that meant spotting wild goats or deer in the car-free streets, for others it may have been a grey squirrel or urban fox in the garden. My hope is that as we recover from the pandemic we don’t lose sight of that link to nature, and that as society moves forward it will be with increased understanding of and respect for the way the natural environment supports and underpins everything we do. My ambition for the next phase of the Mammal Society’s life is to really raise our profile to that of a household name alongside larger charities such as RSPB and WWF. I want to make sure that we develop our communications strategy, and through our website, publications and social media engagement, reach a wider audience and raise the profile of British mammals and their conservation in line with our charitable objectives. I want us to continue delivering the highest quality of scientific research and to proactively engage with government and the media on mammal conservation and management issues to contribute to the delivery of evidence-based policy.

5. As stated on your website: Britain is now recognised as one of the most nature-deprived countries in the world. Are you broadly optimistic about the future of mammals in the UK?

I think we have to be; the only viable option for human society is to live in harmony with nature. This year is a hugely important one for nature with the COP15 meeting in China in October on the post 2020 Global Biodiversity Framework, and the related COP26 meeting on climate change in Glasgow in November. These will be decisive in setting out international approaches to protected areas and sustainable use of the commodities we harvest from nature. Here in the UK, we have clear commitments arising from our exit from the EU, in the government’s 25 year environment plan, and through measures such as mandatory Biodiversity Net Gain in the forthcoming Environment Bill. All the pieces are there, we just need to commit to putting them together into a coherent protection framework. One quarter of British mammals are currently at risk, but it isn’t too late to bend the curve on extinctions and watch our biodiversity flourish again.

6. Finally, for any of our readers who are wanting to get involved with mammal conservation in the UK, what are the most important things that they can be doing right now?

Firstly (obviously!) have a look at the Mammal Society’s website (https://www.mammal.org.uk/support-us/) and you will find all sorts of things you can do to help from sending us records of mammals you have seen to organising a bake sale (hedgehog cupcakes, anyone?). In your day to day life, here are a few things you might try to help mammals.

  • Garden with nature in mind. If you have a garden, try to leave a wild corner with food for wildlife particularly in the autumn and winter. An open compost heap if you have space is helpful to invertebrates, reptiles and small mammals (but don’t add any cooked food!) If you have a pond, make sure the sides are not too steep or add a ramp to make sure thirsty creatures don’t fall in and drown. Consider leaving food out for hedgehogs (cat food, never milk) or badgers (they aren’t too fussy!) if you are lucky enough to have them. Leave small gaps under fences to make sure hedgehogs and other small mammals can move around. If you don’t have a garden, a window-box or a pot of herbs on the doorstep can provide a source of food for pollinators and contribute to biodiversity.
  • One of the biggest threats to nature is how we manage the countryside and as consumers we can all send a message about what we want agri-business to do. Choose products wisely – is there embedded destruction of the countryside in that breakfast cereal? Write to the supermarket or the manufacturer and ask them how they manage their impacts on biodiversity – both directly and through the ingredients they buy in.
  • Write to your local MP and ask them what they will be doing to make sure that even removed from the EU’s strong environmental legislation, Britain will be a leader in environmental protection. The Wildlife and Countryside Act, which is the key piece of legislation for protecting mammal species such as bats, otters and dormice, is under review this year. Ask your MP to vote to retain and add to the strict protection we have for some mammal species and to prevent it being watered down.
  • And most importantly – just go out there and watch mammals. I may be biased, but for me there is nothing better than being out in the countryside early on a spring morning watching the hares chasing around and knocking seven bells out of each other. You might like to stay up late watching badgers or bats, or enjoy the crazy antics of a squirrel on a bird feeder. It’s important that we engage with nature and encourage our children to do the same. If we don’t see and understand wildlife, we won’t fight for it. And, trust me, we need to fight for it.

Author Interview with Sarah Gibson: Swifts and Us

Whirling swifts overhead are evocative of early summer, and their arrival to the UK brings joy to many. In Swifts and Us, Sarah Gibson explores what is currently known about swifts and their ancestry, while also addressing some of the contributing factors to their huge decline over the last few decades. She meets key experts and researchers as well as many determined individuals, all advocating for change to ensure the swifts’ survival.

Sarah Gibson is Press Officer for Shropshire Wildlife Trust, as well as Editor of the members’ magazine. She also regularly writes nature columns for her local magazines and newspapers. Sarah has kindly agreed to answer some of our questions below.

Firstly, could you tell us about where the motivation for your book came from?

I’d become passionate about swifts since moving into a town from the country.  Then I had a long period of illness and would be exhausted after the briefest of conversations and couldn’t even walk up my street – I was so slow I would be overtaken by very old people on Zimmer frames. It seemed as though I’d hit 97 five decades prematurely.

Then I got better and decided it was time to do something new with my life – alongside my now part-time job at Shropshire Wildlife Trust. I knew I could string words together, so decided to research and write a book about swifts to try and inspire others to love and take action for them too.

During your research, did you discover anything especially interesting that you were previously unaware of about swifts?

That hummingbirds are the swift’s closest relatives! Fossil evidence from 52 million years ago found in Wyoming, USA, revealed a bird that is the forerunner of both. The characteristic common feature is a super-strong, stout humerus bone, that would enable the swift to endure and flourish in perpetual flight and the hummingbird to flap its wings 50 times per second as it hovers over flowers collecting nectar. Their shared ancestry seems less surprising when you think about the intense aerial demands of both birds. 

Your book features exceptional and inspirational people that have fought to ensure nest spots are protected and accessible for returning swifts. Do you have any particular highlights or success stories that you’d like to talk about here?

The Crescent Art Centre in Belfast is a cross-community cultural hub, bringing people together from all backgrounds.  It also has a thriving colony of swifts and when major renovation work began 12 years ago, the architects and builders worked with a local swift champion to ensure that access to the original nesting holes was retained and additional holes provided by integrating nest bricks into the walls. This is a great example of how renovation doesn’t have to lead to ruin for swifts.  It can be achieved, if thoughtfully carried out. This swift colony is now a living emblem of the arts centre and its aspirations – uniting people across boundaries. 

What role can citizen science play in surveying and monitoring swifts?

Photograph by Ulrich Tigges

Local surveys to identify swift breeding sites are very valuable. Knowledge of swift colonies can at times make it possible to work with building owners when renovation works are planned, so that nesting holes can be retained. When the data is fed through to local biological records centres, the presence of swifts in particular areas will be flagged up to planners who will sometimes, but not always make it a condition for development that nest bricks should be integrated into buildings.

The RSPB’s SwiftMapper is a useful tool and you can find out about surveying with local swift groups from Action for Swifts or Swift Conservation.

Habitat destruction, climate change and a stark reduction in their food supply are just a few factors contributing to the decline of swifts over the past 20 years – the odds appear completely stacked against them. Post-research for your book, do you feel any optimism for the future of these incredible birds?

Photograph by Piotr Szczypa

Contemplating the global crisis in nature can lead to despair. Our inability to prevent the destruction of wild habitats and the wild creatures that depend on it strikes deep into our souls, but worrying about the future cripples our ability to act, so I try to live in the present. It is what we do now that will shape the future and we need all of our energy to bring better times.

Climate change is inextricably linked to the degradation of nature. At last, there seems to be a glimmer of awakening at a political level to the fact that nurturing nature is essential for all our sakes. The campaign for 30% of land and sea to be protected by 2030 across the world brings hope but it needs a radical reset of values to be achieved.  All of us though, can do something to help bring it to reality. 

Do you have any current projects or plans for further books that you’d like to tell us about?

I’ve just been down to my local cemetery where there’s a project to turn the unmarked graves area into a wildflower meadow.  The yellow rattle seed we sowed last August is coming up, along with cowslips and violets.  It will be a living memorial for those buried beneath and will attract bees and other pollinators.  I’m also keeping an eye on the eaves of a medieval building managed by the town council. Restoration work on the timbers last autumn included six bespoke swift nest boxes – fingers crossed! 

There will be another book but I haven’t written it yet.  It will explore the connectedness of people with nature but I can’t reveal more just now.

Author Interview with David Stroud: International Treaties in Nature Conservation: A UK Perspective

To the casual observer, global summits and the resolutions they produce can seem frustratingly ineffective – repeating cycles of targets set, missed and reset, with no obvious progress. Yet despite the apparent inertia, when used to good effect these processes can be powerful tools for positive change. International Treaties in Nature Conservation: A UK Perspective provides a unique insight into the inner mechanisms of international treaties – their history, development, successes and failures – from those who have spent their lives working with them.

All of the authors involved in this book bring a huge wealth of expertise from their past and current positions within both statutory and non-government nature conservation organisations and academia. One of the authors, David Stroud, kindly agreed to answer a few of our questions.

International treaties are directly responsible for some of the greatest environmental success stories in modern history. But despite their importance, their role in nature conservation is not one many of us are familiar with. How important do you think it is that the mechanisms of these treaties are more widely understood?

It’s hugely important. Not only do these treaties establish some of the most important conservation objectives, but they provide a means of learning from other experience. Typically, international treaties set a broad goal – such as ‘the wise use of wetlands’ in the case of the Ramsar Convention – but are much less prescriptive as to exactly how this will be delivered nationally. Accordingly, there is much to learn from the broad diversity of other national conservation experience in implementing treaty obligations. Such comparative experiences make these treaties fascinating and their study valuable.

They also provide important drivers of national conservation policy. Thus, for example, it was the obligation under the African-Eurasian Waterbird Agreement to phase out the use of lead gunshot in wetlands by 2000 that created the policy incentive resulting in legislation across the UK to that effect from 1999.

There has been a great deal of uncertainty surrounding the departure of the UK from the European Union, and what this means for conservation. In terms of environmental protection and influence during the development of international treaties, what are the implications of leaving the EU?

Lots of issues here! As we explain, there are also serious risks to standards of environmental protection, especially the removal of strong compliance mechanisms that hold government to the environmental obligations it has assumed, and for which proposed domestic replacements look far from sufficient and have yet to be introduced. That said, some aspects of EU policy, most notably the Common Agricultural Policy, have driven significant harm to nature and to natural systems, and here the promise (as yet unrealised) of a new domestic approach which confines the payment of public money to the delivery of public goods, could mark a significant improvement in the state of nature in the farmed environment.

But there is also a risk that there may be an appetite to replace well-established processes and priorities, developed in partnership with EU states, with unique UK approaches, without reference to their efficacy. Whilst there is always room for improvement, including of existing EU processes, it is important that any such improvements build on existing systems and lessons learnt, and avoid causing delays and disruption that would take time we do not have, given the urgency of the environmental challenges we face.

Many aspects of environmental protection are inherently international in nature, with neither species, habitats nor many of the factors which drive their decline respecting national boundaries. As such there is a clear and ongoing imperative for international cooperation and alignment. The UK, outside of the EU, could take this opportunity to drive up ambition, but risks having less influence on environmental policy development, and becoming increasingly remote from wider thinking and ideas both within the EU and beyond, unless UK governments take pro-active steps to rebuild lines of communication and forums for engagement.

Chapter 8 ‘The impact of UK actions on an international scale’ goes into detail about the UK’s contributions to nature conservation beyond its borders, whether these be, for example, monetary, scientific research, or the role of UK non-governmental organisations (NGOs). In your opinion, do you think the UK is doing enough?

The UK is doing a lot, but by no means enough. Formal financial inputs to international treaties (which we estimate as £2,001,000 in 2019/20) are frankly trivial compared to either the size of the UK government budget in the same year (£842,000,000,000) or indeed the immensity of the issues to be addressed. Whilst both climate change and biodiversity loss have been recognised as ‘crises’ or ‘emergencies’, yet to date, it is hard to see responses from the UK, let alone the wider international community reflecting this, or being much more than complacent ‘business as usual’. And these will have no realistic chance of success.

Following on from the previous question, this book highlights the role and importance of NGOs (and a number of the authors themselves have been or are currently involved with NGOs). Do you think NGOs should have more involvement in environmental policy, both within the UK and on a global scale?

NGOs have a critical role to play in international conservation, both representing ‘civil society’ and also – in many cases – holding considerable technical expertise and knowledge, essential to the effective conservation delivery. Yet the dynamic of relations with governments is interesting! NGOs are not uninterested parties being driven by their own organisational priorities, responsive to their memberships, and typically having developed country perspectives. Their interests can sometimes be limited to a single species (witness the many NGOs concerned with charismatic megafauna such as lions and elephants). In contrast, and especially in democracies, governments have wider responsibilities such as the need to maintain economies, create infrastructure, or alleviate poverty.

The role of NGOs in pushing governments to deliver strong outcomes for the environment is critical and they have a key role, working with government, in practical implementation ‘on the ground’. In the UK, there are typically good relationships between government and NGOs, yet we outline considerable scope for improvement. However, within the UK governments, there can be an attitude that sees environmental NGOs as the problem rather than an essential part of the solution. Which is unnecessary and regrettable.

This book delves into the history of international instruments (such as Agreements, Conventions and legislation), and it is pointed out that fewer new treaties have been made since the early 2000s. Why do you think this is the case?

There are probably two issues at work here. An international landscape of ever proliferating treaties may not be particularly efficient means of engaging the attention of governments. Indeed, one would hope that at some point we see treaties retired following fulfilment of their objectives. Unfortunately, the state of the world is such that we seem far from this eventuality.

It is possible that we already have treaties covering all the relevant issues. However, whilst the ‘big stuff’ (climate change, migratory species, wetlands, trading endangered species) is indeed covered, there are certainly other ‘gaps’ – for example effective regulatory systems for sustainable harvesting of marine resources (to replace the very many completely ineffective fisheries treaties).

Additionally there seems to be an ever-growing culture of legal risk aversion within governments. This, and a retreat to more nationalistic political outlooks in many countries, is not supportive of new treaty-building.

In November, the UK will host the next UN climate change conference COP26 in Glasgow. What do you envisage, or hope, will be the outcome of the conference?

Hoping and envisaging are two very different things! I’ll stick to hoping for now…

It’s human nature to defer difficult decisions: why do today what one can put off till tomorrow? This is especially the case for governments faced with decisions that have difficult political consequences. Essentially the challenge at COP 26 will be to deliver on the aspiration agreed in Paris to hold the global temperature increase to less than 1.5 oC above pre-industrial levels. Unlike the quota-based approach of the earlier Kyoto Protocol, the Paris Agreement aims to build to necessary levels of global emissions reductions from bottom-up – through collective ‘Nationally Determined Contributions’ (NDC). After years of deferral of the difficult issue of how to do this, now is finally the time to deliver. Already, there is much diplomatic peer pressure – led especially by UK and USA – to encourage ambitious NDCs. But whether we get to levels that will deliver the Paris Agreement objective remains to be seen. It’s critical that we do as time is running out!

But even if those pledges are made, it will be essential for UK to work with, and support developing countries in particular, in their transition to zero carbon futures – given all the societal issues and political stresses that will arise.

International treaties are sometimes criticised for being ineffective, and this book describes some of their flaws. How valuable have treaties been in nature conservation?

Well, for those involved in any human endeavour, it’s always easy to see how things could be improved, or work better, and international treaties are no different. But despite imperfections, these treaties are critically important in shaping how we do conservation – in particular in establishing collective long-term objectives – goals that stretch beyond the short-termism of national politics.

Yet whilst the legal treaties specify those things that need to be done to deliver their objectives, as important in the long-term is the community of practitioners that gather around a treaty, regularly meeting and working together in order to drive forward its implementation. This includes counter-part government officials in the signatory governments, relevant NGOs, interested academics, and representatives of different but related treaties. All bring something to the table, and it is through their collective support for, say wetland conservation in the case of the Ramsar Convention, that is so important.

Author Interview with James Lowen: Much Ado About Mothing

James Lowen is an award-winning writer whose work is regularly featured in The Telegraph, BBC Wildlife and Nature’s Home, among other publications. He is also an editor, lecturer, consultant and keen photographer.

From hiking up mountains, to checking his garden moth-trap with his daughter, Much Ado About Mothing is a wonderfully written, engaging account of James’ travels in search of Britain’s rarest and most remarkable moths. James has kindly agreed to answer some of our questions about his latest book below.

Could you tell us a little bit about your background and how you came to write Much Ado About Mothing?

I’m a Norfolk-based naturalist and author who has written 12 books, all broadly sitting in the nexus of wildlife, travel and conservation. Two of those books: A Summer of British Wildlife and 52 European Wildlife Weekends, won Travel Guidebook of the Year awards, which was most pleasing and inspired me to both attempt some longer-form writing (Much Ado About Mothing is fundamentally a travel narrative – an exploration of Britain) and take on a more ‘challenging’ topic. And what could be more challenging than championing the very animals (moths) that the general public purports to hate? 

I could readily understand where so many people were coming from in harbouring disdain for moths. For decades, I was also virulently anti-moth, (pre)judging them as uninteresting and usually irritating little brown jobs that remained invisible yet destroyed my suits. However, when a friend showed me a Poplar Hawk-moth, I remember the date precisely: 7 July 2012, my world changed forever.  Wrapped in silver and grizzled with iron filings, this sweetly furry being opened my eyes, brought me to my senses and revolutionised the way that I engage with nature. Over time, I came to appreciate that moths provided a huge variety of incredibly rich tales about ecology and evolution, camouflage and conservation. The more I learned, the more I felt that moths were unduly maligned. So I set out to champion these underdogs through telling their stories in this new book, aiming to challenge people’s preconceptions, correct common misunderstandings and reboot our collective attitudes. 

I really enjoyed reading about you and your daughter’s shared excitement when visiting your moth-trap. How do you think we can best encourage environmental awareness in young people on a broader scale?

First up, my daughter and I came to believe that moths provided surprisingly good ambassadors for natural beauty. This is by dint of their unexpected accessibility (there are probably hundreds of species living covertly around your garden), their unanticipated beauty (many moths ‘out-colour’ our butterflies!) and their welcome placidity (unlike most flighty insects, moths typically sit peaceably, thereby allowing prolonged perusal). To a certain extent, I think the same virtues, when converted into principles, apply to encouraging environmental awareness in youngsters, because there’s no substitute for first-hand experience. Let’s increasingly make wildlife accessible through urban nature reserves: Carlton Marshes on the outskirts of Lowestoft is a good recent example. Let’s showcase the beauty of animals and plants, running events that draw people’s attention to experiences that they would likely otherwise miss. And let’s put particular effort into helping people see non-skittish creatures: a close-up encounter with a ladybird is more likely to achieve a lasting impression than a distant view of a flying bird. 

Your book is filled with extraordinary and surprising facts about moths. Do you have any particular facts or discoveries that you’d like to share with us here?

Gosh, there are so many amazing factual nuggets that it’s hard to pick just a few. For a start, I love moths’ tales of mimicry (clearwings disguise themselves as wasps), camouflage (some moths conceal themselves as desiccated leaves, twigs and even bird poo) and migratory prowess (tiny, fragile creatures flying a thousand-plus miles). There’s wackiness too: china-mark moths, whose caterpillars live underwater; Sandhill Rustic, whose adults can swim underwater; Scarce Silver-lines, which sings from oak trees; various moths that are engaged in an evolutionary arms race with bats; Indian Meal Moth and Wax Moth, whose caterpillars can digest polyethylene and polypropylene (perhaps conceivably hinting at a solution to the global plastics problem?); and even one New World moth whose cells have proved critical for producing the Novavax COVID vaccine.

In terms of personal discoveries, dedicating a year to moths provided a rich vein of opportunities to try and push the boundaries of knowledge, particularly where this helped conservation organisations. Two finds particularly stand out. Helping out on a Lincolnshire Wildlife Trust survey, we came across the first adult female Marsh Moth seen in Britain since 1948; in the intervening seventy years, only males of this quixotic species had been seen! Then, within a mile of my Norwich home, I contrived to track down a new site for one of our most threatened and poorly understood moths, Marsh Carpet. As far as I am aware, the three we caught were the only adults seen anywhere in Britain that year and more than anyone had caught in a single night for years. Even better, this set in train a relationship between Butterfly Conservation and the land manager (Environment Agency), which should help protect the moth here. Both discoveries speak volumes about both how much we have to learn about these wonderful animals and how readily even inexperienced and distinctly amateur moth-ers can make tangible contributions to conservation.

Which aspect of documenting the moths did you find the most challenging?

In a year-long quest to see rare and remarkable moths across the whole of Britain, failure constantly whispers its name. It only takes one thing to go wrong, from bad weather, early flight season or late emergence to inept choice of survey sites and elusive species, for the entire pursuit to fail. With relatively inflexible dates to boot, we really were reliant on everything going right on every trip, which is a high-risk strategy when, for example, driving eleven hours to Scotland’s Ardnamurchan Peninsula to look for a particular sun-loving, day-flying moth. I guess the other thing to emphasise is that whereas moth-trapping in your garden makes for gloriously lazy wildlife-watching, simply flick the switch and let the insects come to you, surveying moths in remote places is contrastingly hard work. After a long drive, often on the back of little sleep, you need to lug heavy generators and a fleet of moth traps up steep slopes or across difficult terrain. And then you need to stay alert all night to make sure you don’t miss anything. I didn’t get much sleep that year…  

You mention in your book that climate change is fluctuating in its effect on moths, with some species thriving in the warmer temperatures, while others are under much more pressure. Having finished your book, do you feel hopeful for the future of lepidoptera?

Yes and no. Britain’s moth ‘balance sheet’ is pretty complicated, as a recent report by Butterfly Conservation shows. Since 1900, we’ve gained nearly 140 new colonists, but perhaps fifty species have gone extinct. Others seem likely to follow: roughly one in eight of our larger moths are nationally threatened or near threatened. Four times as many species are enduring long-term declines as long-term increases and that includes previously very common and widespread ‘generalist’ moths such as Garden Tiger and Garden Dart. Most worryingly of all, one-third fewer moths are flying today than fifty years ago.

On balance, that’s a gloomy picture. But there’s hope too. Among several environmental organisations, Butterfly Conservation is doing ever more to save moths, from an initiative to connect populations of Barberry Carpet to intrepid endeavours to safeguard the UK’s only site for New Forest Burnet. This is underpinned by surging engagement with moths among folk interested in nature. During the first COVID lockdown, retailers sold out of moth traps such was the demand for the kit. In 2020, nearly 75% more people submitted records of moths to Devon’s county recorder than the previous year. There’s definitely a growing wave on enthusiasm and passion for moths, and that’s got to be a very good thing. 

Do you have any other projects in the pipeline?

Much Ado About Mothing is a book about people as well as place and moths. One of the things I learned during my travels is that many people are deterred from entering the world of moths by the difficulty of identifying them, ‘all the moths look the same’ was a regular refrain. Some brilliant field guides to moths exist, but there seemed to be a demand to complement them with a book that helped newcomers to the hobby easily put a name to our commoner species. The result is my next book,  Britain’s Moths: A Gateway Guide, which came out in September 2021. It aims to be a ‘gateway’ to both the enchanting world of moths and to those more detailed field guides. I hope it inspires more and more people to discover these amazing animals – and then fall for them, just as I have done.
