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.

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.

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.

Seabirds, and a Short History of Illustrated Bird Guides

Seabirds by Peter Harrison, Martin Perrow and Hans Larsson represents the latest in a long history of exquisitely illustrated bird identification guides. An update of the original 1983 publication of Harrison’s, it covers all 437 known species of seabird, from seaducks and grebes to cormorants and pelicans. The publication of this beautiful and comprehensive book has prompted us to take a look at some of the history surrounding illustrated bird guides over the past century.


Title page of the History of the Birds of Europe

At the end of the 19th century, there existed only a few professional bird illustrators. These were usually employed by wealthy patrons, drawing and painting species as requested for private collections and portfolios, with subjects chosen to reflect their patron’s specific ornithological interests. By the turn of the 20th century there were a small number of illustrated bird guides available commercially, such as H.E. Dresser’s A History of the Birds of Europe, published in nine parts between 1871 and 1896. However, these were extremely expensive to purchase due to high production times and costs.

One of the first widely available bird books, The Observer’s Book of British Birds, was published in 1937. Illustrated by Archibald Thorburn, who was eager to embrace the new age of print, the book included plates that showed species in a natural setting and was incredibly popular with a post-war audience. This was closely followed by The Handbook of British Birds by H.F. & G. Witherby (1938-1941) which consisted of five volumes illustrated in colour. These were later combined into a single volume: The Popular Handbook of Birds (1962). At this time, most illustrations were based on museum specimens, as fieldwork was limited by poor optics and the cost of travel, and very few photographs of live specimens were available. Because of this, images, although technically accurate, often missed details of ‘jizz’ and other useful field characteristics as well as seasonal differences in plumage.

Tunnicliffe’s ‘What To Look For In…’ series was popular with both adults and children during the post-war years.

The years and decades following the second world war saw a growing interest in birds in Britain, helped considerably by the RSPB which encouraged the creation of bird art and viewed it as a useful tool for inspiring public interest. At this time, Charles Tunnicliffe’s two albums: Bird Portraits and Wild Birds of Britain, alongside his four What To Look For In Spring/Summer/Autumn/Winter books were incredibly popular with both children and adults. Unusually for the time, Tunnicliffe only worked from real-life specimens which gave his illustrations a rare lifelike vibrancy. (Tunnicliffe is also well known for his illustrations of country life and the original wood engravings included in Tarka the Otter).

The late 1940s and 50s saw the publication of the first ‘modern’ field guides, in which much more attention was paid to identifying characteristsics, behavioural details and notes on confusion species. Of these, the Collins Pocket Guide to British Birds, illustrated by Richard Richardson and the Collins Field Guide, illustrated by American artist Roger Tory Peterson, were by far the most popular. While the Pocket Guide grouped birds by size and similarity, with no regard for taxonomic relatedness, Peterson’s book arranged birds taxonomically, a difference that split readers in their preference for each style.

Volume VIII of the ambition Birds of the Western Palearctic

The 1960s saw a huge ecological awakening in Britain, and an increased interest in the natural world. Popular bird art at this time also experienced a boom with the arrival on the scene of talented artists such as Basil Ede and Robert Gilmore, the latter of who was instrumental in forming the Society of Wildlife Artists (SWLA) in 1964. The decades following were a wonderful period for illustrated bird guides and a number of key publishers now found that it was financially viable to produce these in much higher numbers and successfully market them to the general public. Notable publications from the 1970s include the Hamlyn Guide to the Birds of Britain and Europe, The Collins Pocket Guide to Birds of Britain and Europe and the extremely ambitious Handbook of the Birds of Europe, the Middle East and North Africa, The Birds of the Western Palearctic.

The 1980s were notable for the arrival of the first modern family monographs, beginning with Seabirds in 1983, beautifully illustrated by Peter Harrison. Unlike general field guides, these focused exclusively on a single family of birds, and were incredibly popular. Seabirds was closely followed by Shorebirds, illustrated by Peter Hayman, and Wildfowl, illustrated by Hilary Burn. However, the most ambitious and well-known example of this format is the Handbook of the Birds of the World which stands at 16 volumes, published by Lynx over a period of 20 years.

Collins Bird Guide

Still, expectations continued to rise and the quest for the perfect field guide continued, until the Collins Bird Guide finally appeared in 1999. Renowned globally for the quality of the artwork – which is considered to be exceptional, both aesthetically and as an identification aid – this book has remained the stalwart companion for huge numbers of birders over the past two decades. The third edition, due to be published this year, features expanded text and additional colour illustrations.

More recently, a number of ambitious, large-format illustrated bird guides have been published. All the Birds of the World, published by Lynx in 2020, features more than 20,800 illustrations, covering 11,524 species. Collins Birds of the World, published a year later in 2021, is the complete collection of the Collins Field Guides’ incredibly detailed, accurate and beautiful bird paintings, brought together in one comprehensive volume. The all-encompassing guide featured 10,711 species, including 301 full-colour plates.

Seabirds is a wonderful continuation of the rich history of illustrated bird guides and is a shining example of a book which is both invaluable as an identification guide, and treasured as a work of art.


SM4/SM4BAT SD Card Compatibility Fix

This is a Technical Support Bulletin from Wildlife Acoustics regarding problems that can occur when using the SM4 family of recorders with certain SD cards.

Overview

A number of customers have recently reported deployment problems when using SanDisk Extreme and SanDisk Extreme Pro SDXC flash cards with their Song Meter SM4 family recorders. The issue can affect all Song Meter SM4 family products including the SM4, SM4TS, SM4BAT-FS, SM4M, and SM4MU (but excluding SM4BAT-ZC).

The failure generally manifests with schedules that make continuous back-to-back one-hour recordings and can result in recordings being lost. Corrupted .WAV recordings with a 256KB length and/or many .sm4dump files on the card are both indications. The issue only rarely affects schedules with short duty cycle recordings such as 10 minutes on the hour, or on triggered recordings on the SM4BAT-FS.

Note: Many of the above symptoms are normal at the end of a deployment as batteries fail. What is unique to this issue is it can occur while the batteries are fresh.

Solution

Wildlife Acoustics have released firmware version 2.3.3 that corrects this problem and may improve interoperability with other flash cards as well. We strongly advise customers to update to this latest version as soon as possible whether you are seeing issues or not. The firmware is available on the Wildlife Acoustics website after you log in to your account here: https://www.wildlifeacoustics.com/account/downloads/sm4.

Firmware version 2.3.3 also fixes an unrelated issue, introduced with firmware 2.3.1, which could result in corrupted cards that are formatted in exFAT and have the “dirty bit” set (this indicates an issue with unmounting the card previously).

Note: If you experience card corruption, Wildlife Acoustics have tools that can possibly recover recordings off the card. Contact their support team using the details below for more information.

Campaign to ban the use of peat-based composts in the UK

A UK campaign, headed by Professor Dave Goulson, has called upon the government to ban the use of peat in garden compost by the end of 2021.

In 2011, voluntary targets were set by the government with the aim of ending the domestic sale of peat-based composts by the end of 2020. But, in a recent letter to the environment secretary, George Eustice, Goulson explains that these targets have been an ‘abject failure’. The letter, which has been signed by a long list of notable conservationists, scientists and gardeners – including Alan Tichmarsh, Isabella Tree and Kate Bradbury – goes on to suggest that banning peat-based composts before the COP26 climate conference is a vital step in demonstrating the UK government’s dedication to addressing the climate crisis.

Why is peat important?

Globally, peatlands store half a trillion tonnes of carbon; this is twice as much as is stored in the world’s forests. In the UK alone, peatlands hold more than three billion tonnes of carbon although, worryingly, only 20% exist in a natural or near natural state. Peatlands also provide important habitat for many species of plants and animals and play a critical role in reducing flooding.

As well as the extraction of peat for use in the garden trade, these areas are under threat from overgrazing, draining (so that land can be made suitable for farming), and burning of the surface heather, particularly on grouse shooting estates.

Peatlands grow from the slow accumulation of dead plant material in wet terrestrial habitats and take an incredibly long time to form. When the peat is extracted or damaged, the stored carbon that has built up over centuries is released into the atmosphere. Because of this, the UK’s peatlands are now acting as a net carbon source, rather than an environmentally critical store.

How can I help?
  • As a gardener and consumer, one of the most important things you can do is to commit to only buying composts that are peat-free. Or, better still, if you have the space, try making your own from kitchen and garden waste. As stated in Goulson’s letter ‘Unearthing this precious store of carbon to use in the garden is needless, given that there are high-quality peat-free alternatives available’. Following a survey conducted by the Wildlife Trusts, only two garden retailers declared an end-date for peat sales: Travis Perkins in 2021 and Wickes by 2025. Other retailers, including B&Q, Asda and Lidl said they were committed to phasing out peat products but gave no date.
  • For anyone purchasing plants from nurseries, the Dogwood Days blog provides a comprehensive list of plant nurseries that are peat-free on site and/or committed to sourcing peat-free plants.
  • Sign the petition to ‘Ban the use of peat in horticulture and all growing media by 2023‘. The deadline for this petition is 6th June 2021, and 10,000 signatures are required to ensure a government response.
  • Follow and share the #PeatFreeApril campaign on Facebook, Instagram and Twitter and help to spread the world among your fellow gardeners.

Nurture for Nature: Interview with Dr. Amir Khan

Dr. Amir Khan is a GP, well-known for his regular appearances on Lorraine and Good Morning Britain. As a lifelong lover of wildlife, he is also ambassador for the Wildlife Trusts and Butterfly Conservation. He is passionate about connection with the natural world as a mutually beneficial practice which can not only improve our mental and physical health, but is also necessary to ensure the conservation and biodiversity of local areas.

From April this year, Dr. Khan is fronting Butterfly Conservation’s Nurture for Nature campaign which aims to get people involved with the wildlife in their gardens and local wild spaces. We recently chatted with him about the campaign as well as his love of the natural world.


Your incredibly popular Instagram and Twitter accounts are full of beautiful images and descriptions of your local wildlife encounters. Have wildlife and conservation always been passions of yours?

I have been a lover of wildlife from an early age, my dad and I used to watch nature documentaries together. He wasn’t well enough to get out of the house so I would tell him about what I had seen in the woods or local park. As I got older, I learned about wildlife gardening and the importance of nature on our health. I am passionate about everyone, from all walks of life, having access to nature and that means conserving it. It has such important wellbeing effects that everyone should get to experience. I experienced the benefits of nature on my mental health during the pandemic, when I would come home from the surgery after visiting my patients in nursing homes; nature helped me during these difficult times.

As an ambassador for Butterfly Conservation you are also going to be fronting their new Nurture for Nature campaign. Can you tell us a bit more about this and what it hopes to achieve?

Butterflies and insects are vital pollinators and we need them in our lives to keep us alive! By understanding that by helping nature we are actually helping ourselves, I am hoping people will see the wider benefit of doing simple things that can encourage some of these wonderful creatures to visit them. We have to remember that, at this time of year, many insects are emerging from a long winter and need areas where they can feed to get them going for the spring and summer months. They will then get the mental and physical benefits that being close to nature provides and our insects get more areas to feed, drink and rest.

Hopefully lots more people will be inspired to get into their gardens this year as a result of the campaign. Do you have plans for your own garden this year?

I am really excited about my garden this year. After what feels like a very long winter, I want my garden to feel like a haven for both myself and the wildlife that visit or live there. I am making sure every corner has something in it to entice wildlife. There is nothing better than a summer’s day in the garden, simply watching the insects going about their business whilst you potter about. And knowing they are feeding off the plants and flowers you planted is a lovely feeling.

We’ve also heard that you’re hoping to get into moth trapping! What is it about moths that interests you?

I absolutely love moths! I think they are the most underrated insects in our gardens. They are vital pollinators but have a bit of a bad reputation, probably down to the fact that many of them are nocturnal so we are just not as familiar with them. I want to show people that moths are just as amazing as butterflies and just as beautiful. By doing some moth trapping this summer I am hoping to catch and showcase some of the gorgeous moths that live right under our noses!

It’s fascinating to read about the link between lifestyle choices and their impacts on mental and physical health. How do you feel that a connection with wildlife and an appreciation for nature fit into this picture?

There is so much proven science behind the wellbeing effects of nature. When we are amongst natural spaces, listening to bird song or spending time immersed in nature, our bodies produce chemicals that make us feel content and happy – we produce less stress hormones which can help reduce blood pressure and heart rate, having an overall calming feeling on our minds and bodies. We need to embrace and encourage this as part of our every day lifestyles. This is why we need to conserve green spaces so that everyone can benefit from them.

6th International Berlin Bat Meeting 2021

The 6th International Berlin Bat Meeting was held online from 22nd–24th March 2021 and consisted of a series of varied and fascinating live lectures based around a timely theme: ‘The Human Perspective on Bats’. Over the three days, speakers from around the world spoke on topics such as bat coronaviruses, bat health, human interventions, bats in anthropogenic habitats, ecosystem services, conservation marketing and citizen science. 

The first day of the conference began with a keynote talk from Prof. Felix Drexler (Institute of Virology, Charité Berlin) who spoke about emerging viruses with a focus on bats and SARS-CoV-2. He began by relating the fact that most (around 60%) of human pathogens have a zoonotic origin and that several notable animal-borne diseases have originated in bat hosts (eg SARS 2003, Ebola), although it is currently still debated whether bats are particularly prone to becoming reservoirs of zoonotic pathogens or whether they are just very diverse and numerous in comparison to most other mammals. 

It is a constant challenge to predict where future diseases or pandemics may arise, although important factors appear to be Exposure (whether humans have close contact with the species), Ecology (aspects of the animals’ behaviour or ecology that are favourable for the maintenance and transmission of pathogens) and Evolution (as pathogens are more likely to cross species boundaries if species are genetically and antigenically related). 

Moving forwards, Prof. Drexler suggested that better surveillance is required to respond to cases of zoonotic spillover, as an early response is vital in preventing future pandemics. This is particularly important in peripheral healthcare settings such as where small numbers of cases initially crop up in developing countries. 

Later on in the day, Dr. Jon Epstein (EcoHealth Alliance, USA) continued this theme with a talk that looked at the interconnectedness of animal and human health. He stated that, although the exchange of microbes between animals and species is normal, many aspects of modern life, coupled with our dense populations, have made it more likely that pathogens will make the jump from animal to human. Emerging disease hotspots often show the same trends in terms of high species diversity, large numbers of intensively farmed livestock, high human population densities and land use changes which increase contact with local wildlife. Intensive agriculture, wildlife provisioning and legal or illegal wildlife trade, which often occurs in unsanitary ‘wet markets’, are thought to be particularly problematic. 

 

As stated by Prof. Drexler in his earlier talk, Dr. Epstein concluded that surveillance is critical, alongside appropriate community interventions in cases where spillover has been found. These may include, but are not limited to, reducing the commercial trade of wildlife, building barriers so that wild animals cannot come into contact with farmed livestock and their food, and protecting food sources (such as the date palm sap that is widely collected in Bangladesh and which is often contaminated with saliva and faeces from local flying foxes who have exploited this practice as a useful food source).

Towards the end of the day we were treated to an interactive session from Dr. Tigga Kingston (Texas Tech University, USA) who used the online whiteboard, Miro, to allow the audience to discuss and document what they felt were the biggest challenges for bat conservation. Personal observations were added in the form of virtual ‘sticky notes’ to each category and then the audience was asked to vote on which areas they felt confident in tackling, and which they felt less able to deal with. Persecution of bats, habitat loss, and restrictions on fieldwork/research due to Covid-19 were found to be areas that people generally felt were the most problematic and challenging to address. The talk ended with a brainstorming session to pose various solutions to these issues. 

The second day featured a session on ecosystem services. This began with a keynote speech from Dr. Rudolf de Groot who spoke about the economic importance of bats. Much of his talk focused on the limitations of our current economic models (eg GDP) when it comes to conservation and the environment, as conservation is generally only ever considered as a cost, while ecosystem values and services are rarely factored into the equation.

In a paper published in Nature (1997), the global value of ecosystem services and natural capital was calculated to be US $33 trillion. To put this into perspective, global GDP at the time was US $27 dollars. A later paper, published in Science (2002) estimated that the cost of ecosystem loss was 2-5% GDP per year, and this was expected to increase to 7% by 2050. (Interestingly, and worryingly, the amount currently spent annually on protected areas is US $24 billion, just 40% of the amount that is spent each year on ice cream).

Speaking more specifically about bats, Dr. de Groot listed several of the services that are dependent on bats, including pest control, pollination of more than 300 food plants and 80 medicinal plants, as well as the development of several important vaccines following research into bat viruses.

His concluding remarks reminded us of the importance of raising awareness and spreading the message about the value of the natural world and the services it provides.

On the third and final day of the conference we heard a fascinating talk from Dr. Diogo Verissimo (University of Oxford, UK / Institute for Conservation Research, San Diego Zoo Global, USA) titled ‘Can Conservation Marketing Save Bats’. Many of the sessions from the final day had focused on the importance of social scientists and biologists working together to implement change and promote conservation practices. Dr. Verissimo’s talk took this a step further by discussing how effective marketing can contribute to conservation science.

The problem with bats – he initially stated – is that people don’t like them. In multiple surveys conducted around the world, bats rank low on the list in terms of popularity, and the current Covid-19 situation has done little to improve this state of affairs. He then went on to discuss how Batman is, conversely, one of the biggest media franchises of all time, and this indicates that the way in which a subject or species is marketed and packaged can have a huge impact on its public appeal.

Dr. Verissimo explained that ‘social marketing’ involves the use of marketing principles to influence the behaviour of individuals and communities for the general good. When it comes to conservation this means that we need to show individuals how conservation and ecosystem services have a value to them, whether that is a tangible benefit (such as pollination being vital for the food they enjoy), or intangible (such as pride in a local rare species or habitat).

He went on to suggest that emotions are much better at driving change and decisions than facts, and environmentalists must always remember that everyone in the world is not going to think in the same way as them, as people have different life experiences and therefore different priorities. It is incredibly important to understand the target audience of any marketing campaign and to appreciate that only a small percentage of this audience are likely to be influenced – however, these are the people that need to be focused on. Finding out who they are is a huge part of the process.

In his final remarks, Dr. Verissimo stressed the importance of including social science research when considering conservation and conservation marketing campaigns. Although working in such an inter-disciplinary manner can be a challenge in itself, he believes it is critical for the future of global conservation.

The talks and poster presentations that we saw over the three days of the meeting were lively and varied and it was great to hear from people from a variety of disciplines and backgrounds. I’m certain that everyone who attended would join me in congratulating the organisers of the meeting for an exceptionally well planned and executed meeting that brought together people from around the world to share their expertise and opinions on ‘The Human Perspective on Bats’.

 

 

 

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

Dr Tony Gent

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

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


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

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

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

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

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

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

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

Smooth Snake – by Chris Dresh

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Natterjack – by Chris Dresh

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

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

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

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

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