Wildlife

Water Vole populations are undergoing a national decline in the UK. A new report from the Wildlife Trusts, The National Water Vole Database Project Report, was released last month to document the findings of a nationwide investigation examining Water Vole distribution over the past ten years. Although the report documented a 39% decrease in the number of occupied areas across the UK, it also identified a further 11 new regional key areas of increasing local populations, including several in East Anglia and Yorkshire. The report reveals a bleak national picture with declines across the country due to habitat loss and deterioration, but shows that in the right conditions, and with the help of conservation practitioners, it is possible to reverse their historic decline.

Conservationists have observed active worker bumblebees nest-building in Scotland during the winter months. Unusually mild weather during the Christmas period has led to early awakening from hibernation, and at least two species have started to build new nests early in the winter season. However, the subsequent return of cold weather and the scarcity of winter food sources pose a significant threat to these early nests, risking their collapse. In this instance, fewer queens would be available to build nests in the spring and could contribute to the national decline of bumblebees.

Conservation

The National Trust has announced plans to create 250,000 hectares of biodiverse landscape. Equivalent to 1.5 times the size of Greater London, these nature-rich landscapes across England, Wales and Northern Ireland will address a current national need and are estimated to provide habitat for 1 billion earthworms. Labelled audacious yet achievable, this goal will be actioned on Trust properties, but also in partnership with other organisations, farmers and communities, to create larger tracts of landscape to tackle the climate and nature crises.

Last week, Lynx were reported in the Cairngorms National Park. A total of four animals were illegally released and subsequently captured by the Royal Zoological Society of Scotland (RSS), where they were taken to be quarantined at Highland Wildlife Park (later one sadly died). The source of these animals remains unknown, but experts have raised concerns about the nature of their release – these animals were released in sub-zero temperatures within areas of logging activity, which has been deemed a highly irresponsible action that has drawn criticism from conservationists.

Climate Crisis

2024 marks the first calendar year to surpass the 1.5°C warming limit. Now thought to be the world’s hottest year on record, 2024 has brought the world closer to breaking the international warming target of 1.5°C – although this target is based on long-term temperature averages, last year’s trends signify an upturn in global temperature, with the last decade being the warmest on record. Predominantly due to harmful greenhouse gas emissions, which are still at record highs, this record is met with calls for cuts in emissions over this calendar year.

The UK generated its cleanest electricity ever in 2024, with 58% from low-carbon sources. The amount of electricity generated from fossil fuels has halved in the past decade, with the UK having seen an upturn in the use of renewable energy sources. In the past twelve months, renewables have generated 45% of the UK’s power, and when including nuclear sources, this number totals to 58%. Despite this, fossil fuels are still generating approximately 29% of electricity in the UK, and in order to meet climate and emission targets experts are urging for an accelerated phase out.

Finance

In a ‘landmark’ deal, the world’s first private sector loan based on biodiversity net gain unit models has been granted. Triodos Bank UK has loaned £3.85m to environmental consultancy Nature Impact – the money will be used to purchase a total of 122 acres over two sites, unlocking degraded farmland for biodiversity net gain. These degraded sites will undergo restoration and habitat creation, including native wildflower meadows and wetlands, to enhance their support of British wildlife and climate goals.

Ecologists at Oxford University have designed a new framework to classify how a unit of nature is defined for biodiversity credits. In the review, researchers acknowledge the lack of clarity on how one unit of nature is defined, or how measurements are standardised, and demonstrated the challenges involved with the biodiversity credit market. It presents a framework exploring how biodiversity is quantified, how positive outcomes are detected and how the number of credits can be adjusted to account for uncertainties. The authors caution against biodiversity credits to offset negative impacts, and instead direct focus on avoiding and reducing these factors.

Author interview with James Shipman: Identifying Bats of Britain and Ireland

Packed with insider information, Identifying Bats of Britain and Ireland offers expert guidance on how to identify bats in the hand for beginners and field ecologists alike. Filling a gap between introductory books and more technical volumes, this humorous guide uses detailed images, diagrams and tables to communicate, in simple terms, the fundamentals of bat ecology, survey equipment, techniques required when training for a bat licence and the key features that distinguish one species from another.

James Shipman is an ecologist and bat enthusiast who loves to inspire and motivate future bat workers. He works as a senior ecologist and is involved in numerous bat-related projects. In 2016 he was recognised with the Bat Conservation Trust’s Pete Guest Award for outstanding contribution to bat conservation.

We recently chatted with James about his inspiration for the book, which challenges he faced when constructing a detailed identification guide and more.

Can you tell us a little about yourself, your history of working with bats, and why you chose to write this book?

Originally I planned to work as a game ranger in South Africa, but after returning to the UK, I studied zoology, met my wife and fell into landscaping as my first career and passion. A roofer and a builder both mentioned that I may ‘like’ working with bats, as I’m an animal person, so I explored the idea of them as a hobby!

After a few events I was gripped, and I have now volunteered with bats for nearly 15 years with the intention to install passion, enthusiasm and fun into everything bat-related for volunteers and professionals! Within this time I have helped to train over 50-75 individuals (could be more, I don’t count!) and after nearly 20 years in the landscaping sector, I now work in ecology as a professional.

During my years of training, I found that the more serious and technical books available out there made it hard to learn, and that digestible guidance that was fun, relatable and easy to work with would be beneficial! A lot of my trainees suggested the idea for the book originally, and other bat authors with Pelagic mentioned to the publishers that I would bring a nice approach to ID for ecologists – so here we are.

You have taken a relatable, and oftentimes humorous, approach in the way Identifying Bats of Britain and Ireland was written. Why did you feel this was important, and with that in mind who is this book designed for?

Who said science, research and volunteering can’t be fun! If you enjoy what you do, it’s more fun and you usually get more out of it!

I thought it was important to bring my open, welcoming personality to bats and volunteering into the book, as well as an understanding of how hard it can be to learn in the world of ecology.

Public opinion of bats is often contested, and their associations with rabies and vampirism contribute to this negative perception. This guide contains a section on the myths and rumours of bats – why did you feel it was important to debunk these misconceptions?

Well spotted! It’s one of my favourite parts of any walk, talk, training or even in the book itself. Bats have such a negative view through media – whether it’s Halloween, Covid or other diseases, the positives (not just bats but anything in life) are very rarely talked about! So let’s try and win one for the bats – 2,000 less mosquito bites a night is a good seller!

This guide also features vagrants and species that are extremely rare in the UK. How did you navigate writing about species that you may not have met? And did you find it challenging to construct identification guidance for these scarcer species?

Fortunately I have handled and seen these species abroad in my years of volunteering and training (which I will touch more on in your last question), and I have even been lucky to handle one or two of these in the UK too!

The hardest part of it all was trying to address the elephant in the room (or maybe I should say vagrant in the sky!). I believe there are now 21 species found in the UK – some of these are not proven residents, but are not far off – plus a few others that I chose not to include at the time of publication as records were too scarce!

Were there any other challenges that you came across in the process of writing this book?

As previously mentioned, mental health is important in all areas of life, and I felt that slight delays in finishing this book were due to anxiety of judgement on the final product. However, many close friends and ex-trainees assured me that more positives will come of this work than negatives.

The book is aimed at any level of bat worker and should taken with a light hearted approach. It’s important to address these things when discussing books and publishing – it’s a hard process, and without friends, family and a decent publisher (plus the bats) you can sometimes feel isolated. Luckily, I had the best support from all of the above!

What’s your advice for those just getting started in this field?

Well I could say read the book (haha), there are some good sections about starting out with bats. In short, don’t give up, persist, find bat workers who are open, friendly and passionate with no judgement (they are out there, I’m one of them), and most importantly have fun!

Finally, what’s next for you? Do you have plans for more books in the future?

Um… a break! It’s harder than I ever imagined. However, I would love to eventually write a similar book for bats of Europe! But it may take a while to compile some new jokes!

Identifying Bats of Britain and Ireland is available from our online bookstore here.

This Week in Biodiversity News – 16th December

Environment

An area larger than India has permanently degraded into arid conditions, research shows. Studies by the UN Science Policy Interface have reported that up to three quarters of the world’s land has experienced likely irreversible drying in the past thirty years and now, arid drylands make up 40% of land on earth. Driven by climate change, poor farming practices, excessive water extraction and many other factors, this drying could see significant decreases in crop yield, GDP, and a reduction in the capacity of the land to store water.

A two-year restoration project in Avon Heath Country Park will help to restore a rare habitat. Funded by Defra, £1.2 million will be used to restore this Site of Special Scientific Interest (SSSI) that is home to 2.5% of the world’s remaining lowland heathland. The 210-hectare site provides key habitat for all of Britain’s native reptiles, including Smooth Snakes and ground-nesting birds such as Woodlarks and Nightjars. Restoration work will involve the removal of invasive rhododendron, scrub and pine trees to rejuvenate the heathland and increase the availability of light for low-lying plants.

Conservation

A recent survey has shown that Grey Squirrels are invading Red Squirrel strongholds. Conducted by Red Squirrels Northern England (RSNE), the survey assessed 246 sites for an annual squirrel check. The survey found a rising presence of Grey Squirrels in Red Squirrel strongholds, a trend described as ‘concerning’ by RSNE project officers. These invasive, non-native species were found in 69% of surveyed sites, a 6.8% increase from last year and are now outnumbering Red Squirrels in Cumbria and Northumberland. However, RSNE successfully recorded a 2% increase of Red Squirrels in survey sites, up from 50% in 2023.

Cutting-edge technology is being used to inform forestry management in the UK. Forestry England is employing bioacoustic technology, environmental DNA (eDNA) and drones to inform conservation efforts across multiple sites. EDNA gathered from soil, air and water is being used to build a better picture of community composition across 21 forestry sites, and after four months of sampling, 5,000 unique fungal species and 1,000 invertebrate species have been identified. Bioacoustic data is also being gathered across four areas in Somerset, Dorset, Northumberland and North Yorkshire and will be used to track bumblebee activity through analysis of flight sound. This detailed data will be used to form a new biodiversity baseline to monitor the effectiveness of conservation efforts in the midst of biodiversity decline and climate change.

A reintroduction project has seen the return of Water Voles along the Severn shoreline, levels and moors of North Somerset and South Gloucestershire. Led by the West of England Nature Partnership (WENP) in collaboration with Bristol Zoological Society, the programme is seeking to restore intertidal habitats, wetlands and peatlands, and part of this will be actioned through re-establishing Water Voles in the area. Avon Wildlife Trust have observed evidence that these animals have returned to the area, contributing to the region’s Local Nature Recovery Strategy.

Policy

Angela Rayner has been met with criticism following an interview discussing Labour’s housing pledge. With plans to build 1.5 million homes and fast-track over 150 major infrastructure projects, wildlife protection may take a back seat. Rayner expressed concern for those who desperately need housing, stating that providing homes in the UK should not be sacrificed for wildlife protection. Despite critics deeming the targets ‘unrealistic’, Rayner assured that compliance with national building plans would be mandatory under Labour’s National Planning Policy Framework.

Vital scrubland habitats are at risk following Labour’s announcement to build on grey belt land. Prime Minister, Sir Keir Starmer, has pledged to build 1.5 million homes on redefined green belt land, known as grey belt land. With what some call a ‘vague definition’ of grey belt land, swathes of countryside could be sacrificed for housing developments, in areas that could have been transformed to woodland or wetland habitats. This traditional landscape is vital for wildlife, including birds, reptiles and amphibians, and could prove essential in meeting 30×30 targets.

Interview with Charlotte Mead: The Wildwood Trust

The Wildwood Trust was established in 2002 and is one of the UK’s leading conservation and rewilding trust. The charity aims to push the boundaries of conservation by working alongside nature to fight the biodiversity crisis and halt species extinction using nature-based solutions. Alongside their conservation projects, volunteering opportunities and memberships, they also offer a host of educational courses and workshops across both of their sites.

Wildwood Devon is home to numerous native bat species, and over the last two years, they have been working alongside Devon Bat Conservation and Research Group to create, assist and monitor secure bat roosting sites for the breeding season to support endangered bat populations. In mid-2023, NHBS donated 10 general-purpose bat boxes to support this project. A year later, we had the opportunity to talk to The Wildwood Trust about the results from their first annual species survey on this site, how our donation has aided the project’s success, discuss their goals for the next five years and more.

Firstly, can you tell us about The Wildwood Trust and how the charity began?

Established in 2002, The Wildwood Trust is a native species conservation charity formed to push the boundaries of innovative conservation and rewilding. The charity began after it was decided that a small zoo could be instrumental in educating Kent locals about British wildlife – the zoo was subsequently renamed Wildwood Discovery Park and soon became The Wildwood Trust. Since then, the park has grown and changed, and the Trust has taken on a second site on the Escot Estate in Devon. We recently rebranded and the sites are now known as Wildwood Kent and Wildwood Devon, both working under The Wildwood Trust.

We work with nature to fight the biodiversity crisis, to halt the extinction of species and to create resilient habitats in which nature thrives. Wildwood’s experience and expertise in working with native species means we can work effectively across the UK in many projects, focussing on nature-based solutions to reinstate native species populations and recreate truly wild spaces.

Rewilding, through the reintroduction of keystone species, is the most powerful tool we have. These reintroduced animals alter their landscape by creating the space and complexity for hundreds of other species to thrive.

Which species are you hoping to encourage to the area with the installation of our bat boxes?

We have a number of resident species on site, including Brown Long-eared Bat (Plecotus auritus), Common Pipistrelle (Pipistrellus pipistrellus), Daubenton’s Bat (Myotis daubentonii), Noctule (Nyctalus noctula), Soprano Pipistrelle (Pipistrellus pygmaeus) and Whiskered Bat (Myotis mystacinus). With the addition of the Schwegler 2F Bat Boxes supplied by NHBS, we are hoping to attract a wider range of species, including Barbastelle (Barbastella barbastellus) and Nathusius’ Pipistrelle (Pipistrellus nathusii).

We have since completed our first bat box check and are pleased to see that our resident bats have taken to the boxes, and we have found pipistrelle droppings in multiple boxes. We were also lucky enough to find a female Common Pipistrelle in one of the boxes.

Breeding projects are a key element of the work you do. Why are these programmes so important and do you have a favourite success story that you can share with us?

Breeding projects are incredibly useful for a number of reasons, from maintaining genetic diversity within the population all the way through to providing an alternative to translocations. We work with a number of organisations and charities, who are also involved in captive breeding groups, to maintain high standards of husbandry and welfare to provide a healthy, genetically diverse captive population that can assist in future conservation projects.

I couldn’t possibly choose a favourite as Wildwood has bred and reintroduced many species, including Water Voles as part of development mitigation work and Hazel Dormice into suitable areas of former range. However, the memorable reintroduction of Red Squirrels to Anglesey was a successful project and re-established an iconic species after significant declines following the introduction of Grey Squirrels. We have also joined forces with other major captive breeding collections to implement a national captive breeding group which can assist in any future conservation projects.

How is Wildwood working to combat the effects of climate change?

Many of our rewilding projects aim to facilitate the restoration of native habitats, often through reinstating lost species. A good example of this would be our flagship wilding project ‘Blean Bison’ in Canterbury. Launched in 2019 with Kent Wildlife Trust, the project looked to promote stronger habitats by restoring natural processes and aimed to bring transformational change through a controlled trial with European Bison. To combat climate change, the project is aiming to restore 600 hectares of ancient woodland, a vital natural carbon store that can hold around 30% of the world’s carbon.

What does the Wildwood Trust hope to achieve in the next five years?

Wildwood will continue to be a leader in the field of native species conservation. We will continue to deliver our mission to protect, conserve and rewild British wildlife by building long-term and sustainable partnerships with like-minded organisations. Through collaborative working, we can maximise our impact and bring resilience to our native ecosystems.

Are there any other conservation projects that you’re working on that you can tell us about?

We are proud to be a collaborative organisation and, with like-minded conservation partners, we are now working towards the conservation and reintroduction of several species across Britain, including wildcats, Red-billed Chough and White-clawed Crayfish to name a few.

Part of the national captive breeding programme, the wildcats at Wildwood are involved in the creation of a genetically viable captive population. Our wildcat breeding programme has been hugely successful and in 2020 we announced our collaborative work to restore the European Wildcat to Britain.
As a keystone species, the conservation of White-clawed Crayfish is important for several reasons. The only native crayfish species found in the UK, these crustaceans play a key role in the food chain and are an important indicator species for freshwater health. White-clawed Crayfish are threatened by invasive Signal Crayfish, so our work to support the breeding of these animals through establishing a Devon crayfish hatchery is important in ensuring their survival.
For over 200 years the Red-billed Chough has been missing from Kent, so we have partnered with Kent Wildlife Trust to reintroduce these birds to the cliffs of Dover. The project has now reached its second year of reintroductions, and there are now 19 birds established in the area.

We are always looking for more projects to get involved with so please do get in touch if you think we can help!

NEWTCAM Update November 2024

NHBS is working with the Luxembourg Institute of Science and Technology (LIST) to develop an innovative approach to amphibian monitoring using NEWTCAM, an underwater camera device. In collaboration, we have been refining and testing NEWTCAM to evaluate its potential for biodiversity monitoring. In this update, we share the latest developments in this exciting project.

NEWTCAM Overview

The NEWTCAM is an open underwater tunnel with an integrated camera and lighting system used to automatically capture high resolution images and video of aquatic animals. Specifically developed for Great Crested Newt (Triturus cristatus) surveys, the NEWTCAM works by taking an image of a newt’s underside. These images enable the determination of sex, development stage and individual identification due to the unique spot patterns on each animal. It can be left unattended in the water for several days minimising animal handling, greatly improving survey effort, detection rates, and reducing stress on the animals. The AI-based processing method is classifying images by species and gender (for the four newt species found in the UK), but does not provide population estimates. Individuation (for population estimates) require more AI developments.

The project has two primary aims: to improve the functionality, durability and versatility of the NEWTCAM and to assess its value as a user-friendly freshwater wildlife monitoring method. These aims will be accomplished through a programme of technological development work at LIST laboratories and the NHBS workshop, followed by field experiments conducted by LIST and early user trials. These experiments will test the reliability and robustness of the NEWTCAM for amphibian monitoring and surveying, the NEWTCAM’s ability to detect multiple species and life stages in various habitats, and whether the data produced is sufficient in producing population estimates.

2024 Update

Since the initial field trials, we have continued to refine the NEWTCAM’s design and outer housing, making improvements ahead of a second round of trials.

During the summer, 24 NEWTCAM units were distributed for field trials across Europe, Asia and America, with one unit in California. These trials have the following objectives:

Test the latest version of the NEWTCAM in diverse environments
Gather user feedback on the NEWTCAM design
Improve knowledge on the scope of species that can be observed

During this time, two NEWTCAM devices were deployed in a pond in Luxembourg from March to September, and have successfully produced a time series of larval, juvenile and adult Great Crested Newts. Additionally, a trial in Kent, UK observed adult Great Crested Newts later in the season.

Additionally, our early users have successfully captured first observations of the Marbled Newt (Triturus marmoratus) and Hong Kong Warty Newt (Paramesotriton hongkongensis) with NEWTCAM, and we have observed natural foraging behaviours in Great Crested Newts without human interference.

These initial trials have also highlighted NEWTCAMs potential for monitoring other aquatic species beyond amphibians. Early users have reported observations on a variety of taxa including water beetles and fish, highlighting the potential versatility of the device.

What’s Next?

We will continue to gather user feedback from the ongoing field trials with the first batch of NEWTCAM units to guide further development of the device. Additional field trials will be carried out in the spring of 2025, with the final product planned to enter production by the end of the year.

Q&A with Dr Rebecca Farley-Brown: Head of Field Studies Council Publications

The Field Studies Council has been educating the public on Britain’s natural environment for 70 years, and its publications have played a vital part in making nature more accessible. Three generations of wildlife enthusiasts and conservation professionals have learned about the UK’s plants and animals through Field Studies Council courses and honed their skills with Field Studies Council publications.

The Field Studies Council has published an impressive range of handy fold-out charts, as well as a large series of AIDGAP Guides, which are aimed at non-specialists and are intended to assist with the identification of difficult groups of plants and animals. Their back catalogue also includes a selection of more specialised titles, such as the Royal Entomological Society Handbooks on British Insects, and wildlife distribution atlases produced for the Centre for Ecology and Hydrology’s Biological Records Centre.

We recently had the opportunity to speak with Dr Rebecca Farley-Brown, Head of Publications at the Field Studies Council, about the many courses they run, how they develop their identification guides, their exciting new projects for the New Year and more.

Can you tell us a little bit about yourself and what your role within the Field Studies Council entails?

Dr Rebecca Farley-Brown, Head of Field Studies Council Publications

My role within the Field Studies Council is Head of Publications, based in our warehouse in Telford. I started out in academic research and lecturing before moving to Field Studies Council in 2000. As well as business and product development, I manage the postal sales team that processes orders for our retailers as well as our e-commerce shop. It’s a busy role – every year we mail out over 145,000 guides and aim to publish at least four new ones. We also develop commissioned guides to support citizen science projects.

Developing identification guides is a key part of what we do – for those that take the first step of peering into the garden in search of butterflies and bees on flowerheads, through to guides for enthusiasts, fieldworkers and scientists. I am lucky to have a job which can make a difference, and successful identification is fundamental to survey work and biological recording – if we can’t name it, we can’t protect it.

Founded in 1943, Field Studies Council aims to facilitate an array of opportunities for people to learn about nature, which includes field or outdoor educational classes, residential and day centres, natural history courses and more. How large is your operation and what can be expected from one of your courses?

We have a network of 11 residential field centres and seven day centres across the UK, where we welcome over 100,000 learners from schools, colleges and universities every year. There is no substitute for first-hand experiences in nature, and our charity gives learners a special opportunity to see and explore natural landscapes for themselves. There are wider benefits too – being outdoors is good for mental health and wellbeing.

Our teams provide over 200 natural history courses a year, taking place online or in stunning locations. Whether you’re learning online at a pace that suits you, or in-person gaining practical hands-on experience, all of our courses are led by expert tutors who have a wealth of knowledge, and participants often leave feeling very inspired.

There is always a large demand for professional skills courses from those within the environmental job sector, including topics like habitat surveying, protected species, and understanding Biodiversity Net Gain. Alongside this, we get a lot of enthusiasts and students who are looking to improve identification skills for biological recording and knowledge to further their careers. As an example, our two-and-a-half day ‘Bats: Ecology, Surveying, and Conservation’ course will see you explore areas around our field centre in Shrewsbury. It offers hands-on experience with equipment such as bat detectors, where you will complete a bat survey and analyse the results. Plus, if you’re staying with us overnight, you can have a chilled catch-up with other like-minded people in the evening.

The charity has been creating Field Studies Council identification guides for many years, with a catalogue of over 200 guides to date. These resources cover a vast range of topics from plants and fungi to mammals and insects – can you share with us how you decide which subjects to focus on?

We try to keep an overview of what guides we have, where there are gaps and what needs updating. We had fungi marked as a potential area for a few years, but struggled to find an author until we started working with fungi expert Geoffrey Kibby in 2023, and we now have three WildID guides to distinctive fungi which have been really popular this autumn.

We also think about levels – people need different types of guides depending on their knowledge and experience. Someone starting to look at local wildlife might be happy to know they have found a grasshopper, whereas the enthusiasts and recorders will want to identify it to species level.

That being said, some keys are a challenge to develop and might not make it through to publication. We like to thoroughly test our guides with a range of people, including experts in the subject to make sure they are accurate and useful.

Two wildlife watchers using a Field Studies Council WildID Bird guide in a local field — From beginners to experts, we make guides suitable for all skill levels.

Each guide is beautifully produced and printed, featuring numerous detailed illustrations to aid reliable identification. What process do you go through when selecting an expert illustrator for each guide?

We’re lucky to have good working relationships with several artists, so we have a regular group we tend to use, some of whom are experts in their field too. Sometimes we can reuse existing artwork such as Richard Lewington’s butterflies and dragonflies – the detail on these is exquisite and so accurate, even down to wing venation.

Other times we might need to commission new illustrations, and it is always good to see these develop. Lizzie Harper does many of our plant illustrations, and we recently worked with her on the Waterside Plants WildID guide. Once we have decided on the species and the features that need illustrating, Lizzie will produce sketches that the final artwork will be based on – it’s always an exciting moment when these arrive!

Suddenly you can start to visualise the finished guide. This is the time to check the details. Are any modifications needed? Are there particular features, such as hairs, that need to be brought out in the final painting? All of this is discussed, and then we sit back and wait for the finished artwork to arrive. Lizzie has a lovely blog on her website, which gives an insight into how she develops her artwork.

What are some of the challenges that the charity has faced over the past few years, and what are your hopes for the future of the Field Studies Council going forward?

One of the biggest challenges was COVID-19 – lockdown meant that our field centres were closed, and the majority of staff were placed on furlough. But it was also an opportunity, and sales of the wildlife guides flourished as more people had time to spend outdoors exploring.

During this period, we also developed a couple of online natural history courses. These proved extremely popular, and over time we’ve increased our range to over 44 topics which we run every year. Feedback on these showed that it was a fantastic way for people to learn about nature from their own home, especially with time restrictions or accessibility constraints.

We hope to continue to increase the variety of online training we offer; while improving accessibility, we will also be mirroring these topics in our practical field-based courses to offer progression routes.

With 2025 just around the corner, are there any exciting new projects on the horizon that we can hear about?

We are always working on new guides. Some are still a few years away from completion, but a guide to raptors in flight is nearly finished and an AIDGAP guide to micro ladybirds and another fungi guide are planned for 2025. We also have a sedges guide in development, which will hopefully be progressing to the layout stage next year.

We’re also thinking about beetles, and working on another introductory guide series to common wildlife that we hope to launch in the spring.

WildID Lichen Guide — We have over 100 WildID guides to choose from, covering everything from lichens to ladybirds.

This Week in Biodiversity News – 4th November

Climate Crisis

Concern is mounting over the lack of progress made at COP16. After the historic agreement in Montreal which established targets to reform subsidies and to protect 30% of the planet by 2030, COP16 has revealed that participating nations are not on track to meet these targets outlined in the agreement. In order to reach 30×30, we must designate protected land equivalent to Brazil and Australia combined, and an area of the sea larger than the Indian Ocean. The second week of negotiations has shown little concrete progress on any of these targets, and a slow implementation of these international agreements risks another decade of biodiversity loss.

The UK’s largest supplier of farmed salmon has reported the biggest mass die-off in a decade. Mowi Scotland, a supplier to large supermarkets in the UK, has reported the loss of over one million fish in one production cycle. The supplier has attributed the loss to a rise in sea temperatures, exacerbated by the climate crisis, which give rise to jellyfish blooms – these harmful blooms can cause injury to farmed salmon, risking health issues and fatalities.

Conservation

The final phase of a £4.5 million rodent eradication project is underway on Rathlin Island, Northern Ireland. The island hosts one of the UK’s largest seabird colonies, including Puffins, Manx Shearwaters and Kittiwakes. Seabird species are suffering heavily from rodent predation, and Puffins alone have declined by 74% over a twenty year period. In October, the last of over 6,700 rodent traps were deployed across the 3,400 acre island and over the next seven months, conservationists and volunteers will continue to work on the eradication programme, which will come to an end in 2026.

West European Hedgehogs have been classified as ‘near threatened’ under the IUCN red list. Their populations have suffered significant declines over recent decades and are believed to have halved in more than 50% of its native countries, including the UK. A 2022 study found that British hedgehogs declined up to 75% in rural areas due to growing environmental pressures, including agricultural intensification and urban expansion. Further population declines could see this species under risk of extinction.

A project to remove invasive Stoats from Orkney has seen positive results in the islands biodiversity. The Orkney Native Wildlife Project began in 2019 to remove non-native Stoats which pose significant threats to ground-nesting birds and an endemic vole species. The project is the largest Stoat removal attempted anywhere in the world, with over 6,500 animals removed to date, and has helped to boost wildlife across the island – compared to 2019, curlew and Oystercatcher nest success is three times higher, Hen Harrier nesting success is at its highest, and Orkney Vole activity has increased by 200%.

Environment

More than one third of tree species are facing extinction. Over 38% of the planet’s trees are threatened in 192 countries, outweighing the cumulative number of threatened birds, mammals, reptiles and amphibians. Compiled by Botanic Gardens Conservation International (BGCI) and the International Union for the Conservation of Nature (IUCN), the work of over 1,000 scientists contributed to the assessment of the conservation status of trees. It found that logging, land clearing, pests and diseases were the greatest threats to the group, which could have a cascading effect on other animal and plant species that rely on trees for survival.

Two Bison calves have been born in Blean Woods. As part of the Wilder Blean Bison Project, managed by the Kent Wildlife Trust and the Wildwood Trust, a small herd of European Bison were introduced to woodland in Canterbury, Kent. Three females and one bull were released in 2022 to boost biodiversity and improve the resilience of the environment in the face of climate change. The birth of these calves now brings the herd to eight members, and conservationists hope that the group will continue to expand and benefit the biodiversity of their environment.

Top 5: Acoustic Recorders

Many animal groups use sound to communicate, whether this be for mating and courtship, navigation or general intraspecific communication. These sounds can come in the form of croaks, songs and calls, and are produced by a wide range of animal groups including amphibians, birds, mammals and insects.

Acoustic recorders allow us to listen to these sounds, whether this be for surveying and monitoring, or just for enjoyment. This non-invasive monitoring method allows us to gather data from an environment without disturbing wildlife, and some recorders are designed to be extremely sensitive, enabling users to capture sound from great distances. From these recordings we can identify species, analyse distribution, abundance, ecological community composition and even behaviour and can use the data to inform landscape management.

Acoustic recorders are a valuable piece of kit for ecologists, naturalists or those eager to learn more about the animals in their garden, and we have a fantastic range of recorders to meet these needs. Here we have selected our top five acoustic recorders, highlighting key features of each device.

Nest Boxes for New Build Projects

Nest boxes can be an excellent way to support biodiversity and incorporate additional habitat into new builds or redevelopments. Some nest boxes are specifically designed to cater to certain species, while others are more generalist and are suitable for multiple species. Generally, bird nest boxes consist of a large internal cavity and an access hole in various shapes or locations depending on the target species. They can be made from a variety of materials, however, woodcrete (or woodstone, woodconcrete) is generally preferred due to its robustness, longevity and advantageous thermal properties.

As low impact, wildlife-friendly construction gains momentum, more choice is added to the market each day, and the range is extensive. We are pleased to offer the largest range of integrated nest boxes in the UK. Here we provide an overview of some of our bestselling models and their benefits.

Integrated Swift Boxes

Swift populations have declined over recent decades due to changes in roof design and the choice of materials used to construct our homes and public buildings. This species typically uses existing holes, cracks and crevices to build their nests, especially those in old buildings, so built-in swift boxes are recommended to provide areas for these birds to roost. These boxes provide large internal cavities within the brickwork that can be accessed by horizontally elongated, often downward facing entrance holes. As colony breeders, it is recommended to site multiple swift boxes together, situated with a clear flight path. The boxes should be installed at a minimum height of 5m on a non-south facing wall and should have no less than 40cm between entrance holes.

Bat Boxes for New Build Projects

The range of integrated or built-in boxes designed for bats can be overwhelming. For new developments, or renovation projects, you may be searching for bat boxes to incorporate additional habitats into your build, and support species while providing new infrastructure. With an upturn in low impact, wildlife friendly construction, integrated bat boxes are becoming increasingly relevant in the construction sector. Bat boxes are designed to provide an appropriately sized, predator-free space for bats to roost or hibernate. They are often designed to be built-in to the building itself, whether this be roofing or brickwork and are unobtrusive, often hard to spot, and help to provide various species with a permanent roost.

There are 18 bat species in the UK, all of which use the same areas of buildings to roost in the absence of natural habitats – most commonly cellars, roofs and loose brickwork, among many more. In general, bat boxes should be placed between 3-6 metres high, in a sunny location with around 6-8 hours of direct sunlight. It is also best to avoid placing these in areas around artificial light. For built-in products, woodcrete (or woodstone, woodconcrete) is preferred due to its durability, longevity and good insulative properties.

Here we discuss integrated bat boxes, providing an overview of our selection of bat boxes and their benefits.

Types of Integrated Bat Boxes

Bat Tiles, Bricks and Panels

Tiles, bricks and panels provide bats with an access point to a suitable roosting space, whether this be within the roof, ridge tiles or a cavity area behind bricks and panels. They are designed to be incorporated into the build itself during construction or renovation and should be provided with suitable roosting cavities behind the access point, usually in the form of bat boxes or insulation-free cavity space.
