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!

Conservation

A small group of White-tailed Eagles are to be reintroduced in Exmoor National Park. A project by the Roy Dennis Wildlife Foundation and Forestry England has been working to reintroduce the species since 2019. Focusing on the south of England, the project has been releasing eagles to the Isle of Wight, with 37 birds released so far throughout the project. Exmoor, a region in which this species has bred historically, has been identified as key habitat for White-tailed Eagles due to suitable prey abundance and a long stretch of coastal woodland and moorland. The project plans to reinforce English populations with a small cohort of up to twenty birds, which will be released over a three-year period on Exmoor.

Environment 

The conservation group Alliance for Wales’ Rainforests (AWR) are urging the Welsh government to take urgent action to safeguard Celtic, or temperate, rainforests. The AWR is a collaboration between several conservation organisations including Plantlife, Wildlife Trusts Wales and Coed Cadw, which released a report on the state of Wales’ rainforests – the report revealed that these valuable landscapes are in generally poor condition, with invasive species and significant environmental pressures, such as intensive grazing or air pollution. With over 1,900,000 acres of temperate rainforest in Wales, and only one tenth of this area designated, the group have emphasised that action is needed from the Welsh government to protect the diversity and value of these ecosystems.  

Cranberry farmers are restoring defunct bogs to wetlands in Massachusetts. Several restoration projects have been awarded $6 million in grants provided by New England’s Department of Fish and Game Division of Ecological Restoration (DER) to restore wildlife habitat and improve water quality. The funding will be used to convert disused bogs into wetlands and streams to improve environmental resilience, halt erosion and enhance carbon sequestration. So far, 400 acres have been converted, with hopes to restore an additional 1,000 acres over the next ten years. 

 

Policy 

Defra cuts pose a threat to Britain’s national landscapes.  Defra spending is to be cut by 2% over the next financial year, which could have harmful ramifications for the National Landscapes team who manage 46 regions previously known as Areas of Outstanding National Beauty, including the Chilterns, the Cotswold’s and the Wye Valley. The team is expecting a 12% funding cut, placing significant pressure on an already underfunded and vital service in the fight against climate change. The National Landscapes Chief has warned that these valuable areas could become ‘paper parks’ without adequate funding, and some areas could face a 20% reduction in core services.

COP29 concluded on 22nd November. This year’s negotiations saw heavy criticism, with several headlining stories:  

  • Developing nations were dissatisfied with $300bn in climate finance, with many stressing that the sum is not sufficient to address the challenges that developing countries face.  
  • Azerbaijan’s president, Ilham Aliyev, described fossil fuels as a ‘gift from God’ in an opening speech, sparking debate about the way host countries are selected – Azerbaijan follows authoritarian states Egypt and the United Arab Emirates as COP hosts.  
  • Senior climate leaders have written an open letter to the UN, claiming the conference was no longer fit for purpose.  
  • China is emerging as the next climate leader and was praised for increased transparency about its financial support for developing countries 

The UK has joined a coalition to phase out fossil fuel subsidies. Joined by 16 other countries, including Colombia, Canada and New Zealand, the coalition aims to develop national strategy, remove barriers and facilitate open communication to stop subsidies for oil and gas exploration and production. Thought to be a key step for the UK to reach its wider commitments, the coalition will facilitate the UK’s vision in establishing itself as a clean energy superpower.  

 

Climate Crisis 

A new study has provided an answer to a flurry of elephant deaths. Over 350 elephants, ranging from calves to mature adults, died under mysterious circumstances in Botswana in 2020. A new study using satellite data has suggested that toxic algal blooms of cyanobacteria may be behind these mass die-offs, poisoning the drinking water available to these animals. This research adds to the growing evidence that climate change will have lethal impacts on wildlife as it accelerates – climate-induced disease and mass mortalities are suggested to increase in frequency and severity over the coming years.

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

Field Studies Council logo

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
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.

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.

Our selection of new fungi WildID guides feature beautiful illustrations and have been very popular this autumn.

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.

The NHBS Guide to UK Grassland Fungi

In the past 75 years, over 90% of western Europe’s grasslands have disappeared. These overlooked and undervalued habitats deliver essential ecosystem services that contribute to the function of the planet – they provide key wildlife habitat, can store large amounts of carbon, and are instrumental in mitigating soil erosion and flood management, which is essential as our landscapes adapt to climate change.  

Grassland fungi – such as those outlined in this identification guide – form a distinctive community in these habitats and are key indicators of ancient meadow and unimproved grassland. These species fruit from late summer until winter, and vary greatly in size, shape, colour and texture, from the pale, spherical Earthball to vibrant, slender coral fungi. 

In this guide, explore a selection of grassland fungi groups, as well as individual species, that are commonly found across Britain, and read about their identifying features, size and distribution.   


Groups 

Waxcaps (Hygrocybe)

Waxcap fungi by Jo Graeser.

Identification: There are about 150 different species of Hygrocybe (meaning ‘watery head’) in the UK, and these are a very easily identifiable group. They are characterised by their vibrant, smooth waxy caps that come in a range of bright colours, including red, pink, yellow, orange and brown. When present on the fruiting body, gills are thick but evenly coloured and spaced. 

Distribution: Found in nutrient-poor grasslands, such as grazed upland, and often grow alongside other groups including Pinkgills, Corals, Clubs and Earthtongues throughout late summer and autumn. 

Size: 5-7cm      

 

Club and Corals (Clavariaceae) 

Yellow club fungus.
Yellow club fungus by Jo Graeser.

Identification: These distinctive fungi are easily recognisable by their slender, forking branches that are often rooted in buried wood. They have thick, dense finger or club shaped stalks that grow from a central base, often in clusters, and can be bright yellow, pale pink or white. Coral fungi produce yellow spores from the tip of their branches. 

Distribution: Coral fungi predominantly grow on wood, but can also be found in soil, leaf litter or in short grasses and moss from July to November. 

Size: 4-10cm  

 

Wood Pinkgill (Entoloma rhodopolium)

Brown caps of wood pinkgill mushrooms (Entoloma rhodopolium) via Texas Mushrooms.

Identification: Often found in large groups, this very common pinkgill mushroom is defined by its convex, rounded fruiting body that flattens at the bottom of the skirt. Juvenile mushrooms have tightly packed white gills, and turn a light shade of pink with maturity. They feature a long, smooth, lightly coloured stem measuring 4-9cm long. 

Distribution: Most commonly found throughout the summer until late autumn in deciduous broadleaf woodlands. 

Size: 3-5cm 

Note: Poisonous 

  

Species 

 

Earthtongue fungi (Geoglossum fallax)

Earthtongues – Glutinoglossum by Lukas Large, via flickr.

Identification: A widespread species found across Britain and Ireland, Earthtongues are characterised by black or dark brown stromata with a single, club-like fruiting body growing from a cylindrical, scaly stem. The head is grooved and makes up a third of the body, and it is covered in fine hairs to protect its fertile spores. 

Distribution: Grows in mossy, unimproved and acidic grassland such as old churchyards from August to November. 

Size: 2-7cm  

 

Common Inkcap (Coprinopsis atramentaria)

Identification: Starting off as a smooth, egg-shaped ball with scaled central area, the grey or greyish-brown cap later expands into a soft bell shape with a slight curve at its margin. The stem of an inkcap is smooth and reddish-brown in colour, with hundreds of crowded gills that are white at first, but later darken to brown and black before being auto-digested by the fruiting head. 

Distribution: Fruits in small clumps on tree stumps, buried hardwood, woodland footpaths and parkland from May until November. Some solitary specimens have been sighted on occasion. 

Size: 3-7cm 

Note: Poisonous  

 

Petticoat Mottlegill (Panaeolus papilionaceus) 

Petticoat Mottlegill by Jo Graeser.
Petticoat Mottlegill by Jo Graeser.

Identification: Petticoat Mottlegills are recognisable by their smooth bell caps with a serrated edge, and can be pale brown, greyish-brown or pallid grey, with a darker centre. The fused-together gills are a pale, greyish brown with white edges that turn dark brown and black with maturity, and the thin, cylindrical stem is covered in a fine white powder. 

Distribution: Commonly located in groups on rotted dung from June to November. 

Size: 6-12cm  

 

Common Earthball (Scleroderma citrinum) 

Common earthball (Scleroderma citrinum).
Common earthball (Scleroderma citrinum) by Jo Graeser.

Identification: Ranging from light ochre to mid-brown or green, with a yellow tinge on its upper surface, the Earthballs rounded, fruiting body is attached to the ground with white mycelial threads and is stemless. It has tough, thick skin covered in coarse scales that vary in size and shape, which rupture as the head matures to allow the wind and rain to disperse its spores – which are white when young, and darken to brown or purple with age. These empty shells often remain in sheltered woodland hollows for many months before decaying. 

Distribution: Acidic, well-drained soil near forest paths or on shady banks from July to early December. 

Size: 4-10cm  

 

Common Parasol (Macrolepiota procera) 

Parasol Fungi by Bernard Spragg, via flickr.
Parasol Fungi by Bernard Spragg, via flickr.

Identification: This edible species of mushroom is round in shape with a pale brown, spherical cap that darkens as it nears the crown. The cap breaks into a scaly texture that features a darker brown, central bump called an umbo. The broad, crowded gills of Common Parasol mushrooms are white or pale cream, and the cap has a white flesh when cut into. The tough, fibrous stem is surrounded by a smooth, white double-edged ring decorated with small brown scales that are comparable to snakeskin. 

Distribution: Commonly found on verges, neglected grassland or cliffs, with multiple mushrooms growing in a slightly wavy line, from July to November. 

Size: 10-25cm 

The NHBS Guide to UK Bracket Fungi

Bracket fungi (basidiomycetes), also known as shelf or polypore fungi, can grow on both dead or living trees and cause widespread heartwood decay deep inside its host. These fungal bodies appear year-round depending on the species and produce bracket-shaped fruit on the trunk, roots or branches of the host tree that can span up to 70cm in diameter. 

There are over 1,000 species of bracket fungi worldwide, and here you can explore a selection of bracket fungi found in Britain, detailing their identifying features, when and where they can be found.

Identification: This easy to spot, sulphur-yellow fungus can grow up to 40cm in diameter and features numerous thick, soft, overlapping brackets. When young, they have a velvety texture and orange bands across yellow flesh, which fades to light cream with age. Each bracket is fan-shaped with an undulating margin, while the underside has small pores and produces a yellow liquid when squeezed. 

Distribution: June to November. Mainly grows on oak tree trunks, but can also be found on Yew, cherry, chestnut and willows. 

Size: 10-40cm  

 

Hen-of-the-Woods (Grifola frondosa)

Identification: This large, very distinctive fungus features many flat, interlocking lobes growing from a dense centre attached to the foot of a tree. The underside of the fronds are cream in colour, their top side can vary from brown to grey, and the flesh is pale cream. It’s very common for multiple growths to emerge from one host, and fully grown hen-of-the-woods can weigh several kilograms. 

Distribution: August to November. Predominantly around the base of mature oak trees but they do occasionally grow on other deciduous species. 

Size: Up to 70cm 

 

Turkeytail (Trametes versicolor)

Turkeytail Fungi (Trametes versicolor) by Jo Graeser.

Identification: Turkeytail fungi produce thin but tough semi-circular caps in tight, overlapping tiers that have a slightly hairy, velvety texture. It has a range of concentrated coloured rings that are a mix of black, brown, grey, yellow, purple and green, however the outer ring along the edge of the bell is pale in colour. Often confused with Stereum ostrea (or False Turkeytail) this species can be correctly identified by its white underside featuring hundreds of visible pores. 

Distribution: Can be found on fallen hardwood trees such as Beech or oak throughout the year, but is most abundant from late spring to autumn. 

Size: 4-10cm  

 

Beefsteak (Fistulina hepatica)

Identification: This species of fungi grows in overlapping tiers on dead or dying broad-leaved trees, particularly elm, Beech and Sycamore. Recognisable by their distinctly textured, creamy-ochre brackets, these fungiemerge at soil level at the base of the host tree or higher up the trunk. The underside of the fruit features hundreds of honeycomb-shaped pores. 

Distribution: This fungus fruits in the summer and again in autumn, and is most commonly seen from April to September on deciduous trees and fallen wood on the forest floor. 

Size: Up to 70cm 

 

Southern Bracket (Ganoderma australe)

Identification: Southern Bracket fungi can grow on both living and dying deciduous trees and first appear in the form of solid, white balls. Over a number of years, these develop into large, thick brackets with a flat brownish top and a white underside. As the fungus ages, the smooth top can become ridged and bumpy, and when the underside is scored it produces dark brown marks. This fungus can be easily confused with the Artists Fungi (Ganoderma applanatum), however they can be distinguished by examining their spores under a microscope.

Distribution:  This is the most common species of the Ganoderma genus and fruits on most deciduous trees from April to August. 

Size: Up to 60cm 

 

King Alfred’s Cakes (Daldinia concentrica)

Identification: These fungi present themselves in the form of hard, round lumps roughly the size of a golf ball and are a matt, pinky-brown colour when young. As they mature, they darken to a coal colour and become shiny in appearance. The outer surface is solid but cracks easily, while the inside of the fruit is easily identified by black and grey concentric rings that are darker than the flesh. King Alfred’s Cakes are also known as coal fungus as they can be used as kindling or firelighters. 

Distribution: Can be found year-round in deciduous woodland, especially on fallen Beech and Ash branches. 

Size: 2-10cm   

 

Horses Hoof (Fomes fomentarius) 

Horse Hoof Fungi, Knole Park, Sevenoaks, Kent.

Identification: As evident from the name, this species of fungi is typically shaped like a horse’s hoof, with a pointed top and wide bottom. Featuring concentrated ridges across its exterior and with a fleshy, fibrous inside, their blunt, rounded margin is often cream or yellow. Although they can vary from silvery-grey to black in colour, most specimens are shades of brown. Small circular pores under the bell start off cream in colour and darken to brown once the fruit has matured. On occasion, some Horses Hoofs appear in more of a traditional, flat bracket shape. 

Distribution: Can be found growing year-round on weak, living or dead hardwood deciduous trees, particularly Birch. 

Size: 5 to 45cm 

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.

Birds of Conservation Concern Red List: Species Spotlight

In September, five species of seabird were added to the UK Birds of Conservation Concern Red List. Arctic Tern, Great Skua, Leach’s Storm Petrel, Common Gull and Great Black-backed Gull have joined the list of species most in need of conservation. Each of these species has experienced population declines due to pressures including climate change, avian influenza and habitat loss. Over 30% of all British birds are now on the Red List; the most recent additions joining Kittiwakes, Puffins and Arctic Skuas, among others. An alarming ten out of 26 UK seabirds now feature on the list.   

In this blog we shine a spotlight on these seabirds and explore the threats that have resulted in their addition to the Red List.  


Leach’s Petrel (Hydrobates leucorhous)

Identification: Leach’s Petrel is a Starling-sized bird with a wingspan of up to 48cm. This burrow-nesting seabird is mostly black in colour, except for a white rump with a black line running through it. The wings are angled, with darker wingtips and a lighter coloured ‘V’ over the wingspan and the tail is dark and forked.  

Distribution: Most sightings of this species are recorded around coastal headlands and sea-watching hotspots during autumn. The UK has an estimated 48,000 breeding pairs which can mostly be found on remote offshore islands (particularly in Ireland and Scotland) before migrating to the tropics over winter.  

Threats: Leach’s Petrel was added to the Red List due to population declines and localised breeding concerns. It is thought that more than half of the UK’s population resides at fewer than ten sites, areas which carry the risk of predation by introduced mammalian predators as well as avian predators.  

Fun fact: Leach’s Petrels spend most of their time offshore, close to deeper waters beyond the continental shelf, before returning to underground nests at night.  

 

Common Gull (Larus canus)

Identification: A medium-sized gull with a wingspan of up to 130cm. This species is similar in appearance to the Herring Gull but is smaller in size. It is mostly grey from above, with a grey back and upper wings. The underside, head, tail and body are white. The small bill and legs of the Common Gull are yellow-green in colour and, up close, a red orbital ring can be observed around the iris. Their call is a high-pitched ‘kee’ or ‘kee-ya’ sound.  

Distribution: There are approximately 49,000 breeding pairs of Common Gull in the UK, which breed in the north and west of Britain and Ireland. They are generally widely distributed throughout the country but are found with the highest densities on the eastern side of Scotland. Predominantly a coastal bird, this species has a preference for upland areas and can be seen in towns along the coast throughout the year. 

Threats: Severe declines have been observed over the last 25 years, with over half of the breeding population lost during this time. These losses are due to a number of factors, including predation, habitat loss and degradation.  

Fun fact: Despite its name, this bird is scarcer than other gull species and is found in lower numbers.

 

Great Black-backed Gull (Larus marinus)

Identification: A thick-set, very large gull with a powerful beak. Great Black-backed Gulls are easily recognised by their black upper wings and an impressive wingspan of up to 167cm. The head, neck, tail and underside are white and there are visible white edges to the upper wings in flight. This species has pale pink legs, and a distinctive large yellow beak with a red spot on the underside towards the tip.  

Distribution: There are around 17,000 breeding pairs of Great Black-backed Gull in the UK which can be seen throughout the year in coastal locations. This species is found across the UK but has high densities around the northern Isles and south-west Ireland.  

Threats: Populations of Great Black-backed Gull have declined by an estimated 50% since 1985, brought on by suspected declines in food availability in their natural habitat, habitat loss and threats from entanglement and development.  

Fun fact: The Great Black-backed Gull is the largest gull species in the world. 

 

Arctic Tern (Sterna paradisaea)

Identification: A small, slender seabird with a wingspan measuring up to 85cm. The Arctic Tern is a white bird with a black cap and grey wings. It is streamlined in shape and has a deeply forked tail with long streamers. The legs and pointed beak are red in colour and their calls are hard and repetitive, with a ‘kee-arr’ sound.  

Distribution: There are approximately 54,000 breeding pairs in the UK that can be seen in good numbers around Shetland and Orkney. Arctic Tern can be seen from April to September in Britain, breeding coastally in the north.  

Threats: Arctic Tern populations have undergone long-term declines for several reasons: habitat loss, human disturbance in breeding and feeding habitats, impacted chick survival by avian influenza, and declines in Sand Eels, a critical food source. 

Fun fact: The Arctic Tern has the longest migration of any tern – this species breeds in the Arctic and travels south to summer in the Antarctic.  

 

Great Skua (Stercorarius skua) 

A mottled brown bird standing on long grass. It has a dark grey beak and legs. It is a brown bird with mottled white, yellow, gold and black
Image by Kjetil Rimolsronning via Flickr

Identification: A large, dark brown bird with a wingspan up to 140cm. Great Skua are heavy in build and almost black in colour when viewed at a distance, with white flashes on the wing visible in flight. Up close, their plumage is streaked with black, brown, white and yellow and their bills and legs are black. They have a distinctive gull call – a harsh ‘hah-hah-hah-hah’ sound.  

Distribution: Great Skua can be seen around British coastlines throughout the year, with most sightings documented between April and November. This species is known to breed on northern islands, including Shetland and Orkney during the summer months.  

Threats: Great Skua populations have been severely impacted by avian influenza, resulting in at least 2,500 deaths of Scottish birds since 2022.  

Fun fact: Considered ‘pirates of the sea’, Great Skuas are predatory birds and will hunt small birds, rabbits and rodents.
