Progress towards the recognition of ecocide as an international crime
A motion (motion 061), supported by the Wildlife trusts among other environmental groups, invites IUCN members to support the recognition of ecocide as an international crime. Supporters, including wildlife trusts CEO Craig Bennett, argue that recognition would ensure that no actor can cause severe, widespread or long-term harm to nature without facing criminal consequences. Proponents have argued for decades (including a notable 10-year campaign led by barrister and green ambassador Polly Higgins) that international recognition of ecocide as a crime is essential if we are to collectively mitigate global environmental crises and protect nature. The motion will be considered at the next IUCN World Conservation Congress, set to take place in Abu Dhabi, UAE, in October.
Restrictions on the use of lead ammunition in Britain
Almost all shotgun pellets and bullets containing lead are to be banned in the UK under restrictions which will be phased in between 2025- 2028. The persistence of the usage of lead in shooting has led to the death of an estimated 100,000 waterfowl each year, alongside countless other grit-eating birds, raptors and scavengers. The new restrictions have been welcomed by environmental groups and are consequent to a decades long campaign. The story up to this point was covered in British Wildlife Volume 36.4.

The global impact of chronic oiling
The Guardian and Watershed Investigations have revealed damning statistics which underly a lack of understanding of the extent of oil spills in global seas. Extensive research, through the analysis of hundreds of thousands of satellite images over a five-year period shows that only 474 of more than 90,000 oil slicks from ships were reported to authorities between 2014 and 2019. The figures suggest that the extent of anthropogenic oil pollution has been grossly underestimated.
Lost jellyfish rediscovered
A species of stalked jellyfish, Depastrum cyathiforme, that had not been seen anywhere globally for more than 40 years and had never captured on camera has reemerged in the Outer Hebrides.
Naturalist, Neil Roberts, took the first photographs of the thistle shaped jellyfish in 2023. Its rediscovery, revealed by British Wildlife magazine, has been confirmed by a follow-up search that successfully located another individual. Marine naturalists have called for further exploration to establish whether populations exist outside of South Uist, around wider Britain and mainland Europe.
Course attendees learning small mammal survey techniques at the Field Studies Council’s Preston Montford activity centre
In the lead-up to this year’s National Mammal Week (21st-27th April), NHBS was kindly invited by the Mammal Society a preview of their new Mammal Identification and Ecology residential training course.
The Mammal Society is an active charity and learned society dedicated to the study and conservation of all British mammals. Founded in 1954, the organisation plays a crucial role in promoting research, education, and advocacy for mammal conservation. The Mammal Society works closely with scientists, policymakers, and the public to gather data, inform policy, and raise awareness about the importance of preserving Britain’s mammals species. The society’s efforts are vital in addressing the challenges faced by mammals, including habitat loss, climate change, and human activities.

A golden ticket
I was fortunate enough to receive the golden ticket to this enriching experience – a preview of a new immersive, hands-on training course focused on British mammals. Heading to Field Studies Council (FSC) Preston Montford activity centre, I was looking forward to engaging with ecologists, conservationists, and enthusiasts, all united by their passion for conserving UK mammal populations. I was also excited to gain insights into the equipment and methods used for monitoring mammals and to enhance my own identification skills.
The training course aimed to introduce participants to the skills needed for mammal identification and help us familiarise ourselves with various monitoring methods. These skills are crucial for accurately tracking population trends, population movements, and the factors influencing changes in conservation status. With one in four mammal species threatened with extinction in Britain, gathering detailed data is more important than ever.
The FSC’s centre, surrounded by fields, woodland, ponds, and the nearby River Wye, provided an ideal backdrop for a mix of fieldwork and classroom-based learning. With the added presence of an evening bar, this was a most appropriate venue where course participants could exchange their thoughts and evaluations.
Diving into mammal identification
The course kicked off on Friday evening with a hands-on session preparing Longworth Small Mammal Traps. We strategically placed 40 traps in an area of mixed habitat (the more traps you put out the better the chances of success). We added hay to each trap and baited them with seeds and blowfly pupae to attract rodents and shrews. The next morning, our efforts were rewarded with the capture of a Wood Mouse and a Common Shrew. It was fascinating to learn about the shrew’s high metabolic rate and the importance of providing food in the traps.

Classroom insights and field adventures
Saturday was packed with classroom sessions in a room that had been kitted out with mammal skins, skulls, nests, owl pellets, droppings and publications. The morning session was devoted to gaining a deeper understanding of small mammals and their ecological roles. The afternoon session focused on herbivores, teaching us how to identify the six species of deer in the UK and recognise signs of Wild Boar presence, such as uprooted turf.
A highlight of the day was the field session, where we searched for signs of mammal activity. From tunnels through grass and soil to footprints, droppings and gnawed hazelnuts, the landscape was teeming with evidence of our furry neighbours. The evening session on carnivores was equally engaging, with discussions on the UK’s mustelids, the elusive Wildcat, and the controversies surrounding mammal persecution and reintroduction.
The evening concluded with a session on bats, followed by a thrilling field trip with bat detectors and thermal imaging monoculars.

Sunday morning saw us checking the results from our field monitoring equipment. The most challenging part for me was the classroom session on tracks and signs, where I struggled with a footprint quiz. Dissecting owl pellets was a unique experience, revealing the remains a Field Vole and a Common Shrew in the pellet I looked at.

The final session covered sea mammals, such as dolphins, whales and seals after which a weekend of comprehensive learning was rounded off with a course evaluation.
Post-event musings
The Mammal Society’s training course was an invaluable experience, combining hands-on fieldwork with insightful classroom sessions. I returned with a deeper understanding of the diversity and complexity of the UK’s mammals, as well as the importance of ongoing conservation efforts. Equally, I gained a refreshed appreciation for the profound knowledge and dedication of the members of the Mammal Society. I also learned about some handy wildlife recording apps, such as the Mammal Society’s own Mammal Mapper, and iRecord for all biological recording. Whether you’re a seasoned ecologist or a curious enthusiast, you’re sure to return from this training enlightened and motivated.
Often seen as mere picnic nuisances, the UK is home to a surprising variety of wasps, including both social and solitary species. While many of us will be familiar with the iconic black and yellow social wasps, numerous solitary species display incredible diversity in both form and behaviour. Distinguishing them can seem daunting, but key features like body shape, coloration, and reproductive behaviour can offer valuable clues.
Here, we’ll explore a selection of common wasp species, and some wasp families found across the UK, detailing their identifying characteristics and the typical habitats they can be found in.
Common European Yellowjacket (Vespa vulgaris)
Common wasp DSC_5493_edited-1 by Clifton Beard, via flickr.
Identification: Between 11-19mm in length with striking black and yellow stripes.These social wasps have six abdominal sections, each with one stripe, and there is a very distinguished waist between the thorax and the abdomen, which has black dots and rings. The species has a conspicuous face on a triangular shaped head with a black anchor or dagger shaped mark towards the base, and a pair of long, robust antennae. They have yellow cheeks and yellow legs.
Distribution: Widespread throughout the UK. Common Social Wasps can be found in almost all habitats, particularly grassland, heathland and woodland from mid-March to November.
Red Wasp (Vespula rufa)
Rote Wespe (Vespula rufa) by Frank Vassen, via flickr.
Identification: Growing up to 20mm in length, Red Wasps can easily be distinguished from V. vulgaris by reddish-brown markings on their upper back segments.
Distribution: Widespread, and frequently found in open woodland, moorland and hedge banks from the end of March until September.
Identification: Hornets are Britain’s largest social wasp species. Around 15-35mm in size. The abdomen is yellow and unbanded, with brown markings on the upper parts, while the thorax is black and reddish-brown. Their legs are a reddish brown – a characteristic that can distinguish them from Asian Hornets – and antennae are yellow or brown in colour.
Distribution: Widespread distribution and commonly found throughout England and Wales. Hornets can be found in many lowland habitats and are known to associate with ancient woodland, wood pasture and can be found in parks and gardens in more urban areas. Queens emerge from overwintering in early April, while workers can typically be seen from late June to November.
Identification: Typically smaller than native hornets, this invasive species can grow up to 3cm in length. Their abdomen is dark in colour with fine yellow stripes, and the fourth segment towards the base of the hornet is distinctly yellow orange in colour, while the thorax is entirely black or dark brown and appears velvety in texture. From the front, the head appears orange and the legs have yellow tips.
Distribution: Yellow-legged Asian Hornets were first recorded in England around 2016, after they were accidentally introduced from Asia. They have mostly been recorded in the south of England, particularly the South-east.
Wasp Families
The diversity of wasp families in the UK is vast and presents a significant identification challenge. In this blog, we have chosen to focus on a number of wasp families to demonstrate the wonderful diversity of this group.
Ichneumon Wasps

There are around 2,500 species of Ichneumon wasp in the UK. These small insects can vary in size but generally reach up to 1 ½ inches in length. They exhibit a wide range of colours and patterns, some with brightly coloured bands, and others with more subtle markings. Ichneumon Wasps can be distinguished by a slender sickle-shaped abdomen and a pair of long antennae, each with at least 16 segments. They have a narrow waist, long jointed legs and two pairs of wings. These parasitic wasps inhabit flower-rich meadows, gardens and woodland – they can often be seen around umbellifers or investigating vegetation and dead wood.
The UK is estimated to have 86 Gall Wasps, a group of well-studied parasitic wasps.This group gets its name for a unique reproductive behaviour where adults lay eggs in the soft tissues of trees, flowers and other plants, creating a gall as the larva develop. Usually on the underside of leaves, branches and around acorns, these wasps produce conspicuous galls on their host plant – interestingly, they usually only infect a specific species of genus, for example, Citrus Gall Wasps will exclusively parasitise citrus trees.After overwintering, the larvae will emerge in spring and can be seen throughout summer. They are typically under 5mm in size, shiny, and are black or brown in colour with a humped thorax and wings.
Cuckoo Wasps

Instantly recognisable by their brilliant metallic body colours in shades of blue, green, purple and red, these small chrysidids are also known as jewel or ruby tailed wasps. There are around 31 species of Cuckoo Wasp in the UK, which can be seen in sunny weather from April to October in a range of habitats; particularly in sandy soils around coastal areas, gardens and ancient woodlands. The group are often seen investigating the nests of other Hymenoptera species in order to reproduce – these parasitic species will enter the host nest and lay their own eggs in the host cells. Once hatched, Cuckoo wasp larvae will eat the eggs and larvae of the host species before restarting the cycle – hence the name ‘cuckoo’.

2025 marks the fifth year that NHBS has participated in Plantlife’s #NoMowMay campaign which encourages people across the UK to put away their lawnmowers and let their grass grow wild throughout the spring, with the aim of providing vital habitats for a wide range of species. As in previous years, we requested that the verges and lawns surrounding the premises be spared from mowing or strimming from late April and all through May to allow more plant species to flower.
We’ve seen good numbers of daisies, buttercups and Germander Speedwell alongside a handful of charming clover species including Red and White Clovers and Black and Spotted Medick. Ribwort Plantain, Common Vetch, Ox-eye Daisy and docks are adding height in places and a handful of common grass species are present and swaying nicely.
Common Spotted Orchid
We do have one beautiful Common Spotted Orchid flowering now as June begins, though sadly, there’s not been returning Bee Orchids this year, for the first time while we’ve been participating in the campaign.
There’s been a fair few bees, wasps, flies and beetles visiting the flowers, though invertebrate activity all round has felt somewhat diminished from previous years. Through May we had scattered sightings of Orange-Tip, Peacock and Tortoiseshell butterflies, and now as June is arriving Meadow Browns have emerged.
#NoMowMay is a fantastic initiative by Plantlife that has highlighted the importance of giving wild plants places to thrive through a crucial stage in their lifecycles and therefore enrich and advance the opportunities for pollinator species, and the wider web of life that depends upon green spaces, including us humans. It’s vital that spaces are left wilder for longer than May, and to encourage this, Plantlife are encouraging the public to let their lawns or grassy areas continue to bloom through June (and again, ideally beyond) with #LetitbloomJune! We’re hopeful that our lawn will be left to flower throughout the summer too.
Outside NHBS at the beginning of June 2025
At NHBS we offer a large variety of books for learning more about habitat maintenance, the importance of species who rely on the restoration and reinvigoration of wilder spaces and many helpful field guides for identifying who’s growing in and visiting your local park or garden!
NHBS is proud to celebrate its 40th anniversary, marking four decades of supporting those who work to understand, protect, and conserve the naturalenvironment.
History of NHBS
Founded by Bernard Mercer in 1985 as the Natural History Book Service, NHBS began as a mail-order supplier of ornithology books based in London. Our first catalogue was hand-crafted on a state-of-the-art electronic typewriter! Within two years, we evolved into a comprehensive natural history bookstore, committed to supplying all in-print literature on both natural history and science. Shortly after, we relocated to Totnes in Devon, and we have remained here on the edge of the River Dart ever since.
By the late 1980s, in response to customer demand, NHBS expanded its subject range to include habitat and species conservation, climate change, environmental assessment and more. In May 1995, we ventured online with the launch of our first website, and as digital communication grew, our website and email newsletters became increasingly important, leading to our final newspaper catalogue in 2005.
At the start of the new millennium, NHBS began expanding its range to include products such as bat detectors, trail cameras and moth traps,having recognised the growing demand for nature-based equipment. Today, we offer a comprehensive range of books and practical equipment for ecologists, researchers, educational professionals, and wildlife enthusiasts alike.
“Celebrating 40 years is a testament to the dedication and passion of our team and the unwavering support of our customers. We are committed to continuing our mission to provide the best resources and tools for those who strive to protect and understand our natural world.”

Placed on the IUCN Red List in 2021, Swifts are now recognised as one of Britain’s most endangered bird species, having suffered a staggering population decline of around 60% in just 25 years. These incredible birds return to the same nesting site each year after migrating from a summer in Africa, however due to urban development and land use changes, their natural nesting sites are rapidly disappearing, which is accelerating their already concerning population decline.

In 2024, over 40 residents of two neighbouring streets in Swinton, Salford decided to take action and create their own ‘Swift Street.’ This community-led project saw the creation and installation of over 100 specialist nest boxes, providing essential nesting spaces for their local swift colony. The Swift Street initiative is part of a wider effort to transform Manchester into a Swift City and ensure the long-term survival of these endangered birds.
In this blog, resident Suzanne Pendleton and RSPB Community Engagement Officer Roshni Parmar-Hill tell us about their journey to create the largest Swift Street in the north-west of England.
My Swift Street Experience – Suzanne Pendleton
My name is Suzanne Pendleton, and I am a mum to two girls, Molly and Tess. I have lived in Houghton Lane in Swinton, Salford with them and my hubby for 30 years, and have been involved in the Greater Manchester Swift Street initiative since August 2024.
During lockdown, I started to value spending more and more time in our little garden as so many people did, and whilst I was outside, I spotted a number of birds zooming around, screaming and flying over our house. At first I wasn’t quite sure what they were, so I asked my friend Kathleen and she enlightened me that they were Swifts! Swifts are migratory birds, so when summer ended they left Swinton and headed back to Africa, but every year I eagerly anticipate their return.
Over time, my understanding of this species grew, and I learnt of their declining population numbers – whilst also developing a stiff neck constantly looking up to the sky to watch their incredible manoeuvres! I am privileged to live in a friendly community on Houghton Lane, so I messaged our community group and asked if anyone knew about our Swift population, or where they may be nesting. Initially we were unsuccessful in locating their nesting sites, however we struck gold in Spring 2024 with the help of the Swift Mapper appand discovered we had four nest sites on Houghton Lane and its surrounding roads.
In this time, I’d also discovered that there was another small colony located less that 1/4 mile away, and a resident of this local road got in touch to tell us that Roshni from the RSPB had been to visit their colony and help establish their Swift Street – she then asked if we would be interested in developing our own Swift Street on Houghton Lane. I think we are so privileged that these incredible urban birds choose to nest on our lane, and as their nesting sites are often threatened by redevelopment, having the means to install boxes provides us with a wonderful opportunity to support them.

This project has been a whole-community effort, superbly guided by the wonderful Roshni. With her incredible support and guidance, we used our community group to share the news of the development and launch of our own Swift Street, and we were overwhelmed by the local response. So many families were keen to support our Swift population, and we received requests for over 80 boxes. In January, we were blessed with some bright days, which allowed us to visit each home that had requested a Swift box and advise the families in selecting a suitable aspect and position for their box. As we chatted to more residents about the project I grew in confidence talking about Swifts, and increased my own knowledge too.
Roshni also gathered support from a local college who built our Swift boxes, whilst a local resident, Haldis, made our nest cups. Roshni and several Swift Ambassadors (volunteers who work alongside communities to raise awareness of Swifts and encourage positive action to protect them) then visited our Girl Guiding group to lead some Swift-themed activities which captivated the girls’ interest. They loved learning about the species and contributing to the project by painting our boxes with bird-friendly materials recommended by the RSPB. Saturday 8th March was our first installation day, and local roofer Ryan put up 25 boxes. Since then, we have now installed over 80 along the street, and we are ready for the first wave of our Swift populations to return!

It’s been an absolute honour to be involved in this project, and I feel so lucky that our community can do something practical to support our local Swifts.

I’ve been so privileged to work alongside individuals as passionate and energetic as Suzanne whilst bringing the Swinton Swift Street project to life. This truly is a community endeavour – proving that, to misquote a famous phrase ‘it takes a village to save a Swift’. From Suzanne’s tireless recruitment of her neighbours’ support along her street, and the hard work of her Girl Guide pack painting and waterproofing the nest boxes, to the students of independent skills provider The SkillCentre in Trafford who constructed the boxes, it’s been a joy to see so many people pull together to take positive action for nature.

The screaming calls of migratory Swifts are what first drew Suzanne to this species and fostered her connection. If we want to keep welcoming them back screeching overhead every summer, then they need our help now more than ever to create and protect safe nesting habitats. This incredible species travels a whopping 3400 miles to reach the UK from East Africa every year – crossing 25 countries over the course of 4 weeks in their journey to reach us. Swifts spend most of their time in the air – feeding, sleeping and even mating all whilst in flight! – only landing to nest, which is where Suzanne and her neighbours come in.
Swifts return to the exact same nesting spot every year, but increasingly these nesting sites have been hit by property renovations and the removal of old buildings. This has contributed to a 62% decline in Swift numbers between 1995 and 2020, and the species have now been added to the UK’s Red List of Birds, meaning its amongst our most endangered. However, with the installation of over 80 nest boxes on Suzanne’s street, we intend to grow another new urban Swift colony and build on wider ongoing work to develop Manchester into a Swift City. This project is supported by the expansion of our network of brilliant ‘Swift Champions’ who are leading the development of nesting sites at scale, manufacturing swift boxes and raising people’s awareness and engagement of the project and species through walks, talks and workshops.

As Suzanne and her neighbours now prepare for a special Swift Homecoming Street Party to officially declare it a Swift Street and welcome their bird’s home, all eyes will be fixed on the skies for a glimpse of the street’s feathered residents moving into their new addresses…
Orchidaceae, a family boasting over 28,000 species worldwide, are renowned for their intricate beauty and fascinating adaptations. These perennial plants exhibit a remarkable diversity of forms, even within species, with flowers featuring three sepals and three petals, one of which often forms a distinctive lower lip (the labellum) which is an important identification feature. They rely on diverse pollination methods, often involving intricate relationships with insects and fungi, and are highly specialised to survive in specific habitats.
The UK is home to 57 native orchid species, ranging from common meadow flowers to prized rarities. This blog explores a group of these British orchids and provides information on both their identifying characteristics and distribution in the UK.
Identification: Bird’s-nest Orchids are incredibly distinctive and are named for their unique root system that resembles a bird’s nest. They have no leaves, and do not have chlorophyll, so they rely on nutrients provided by mycorrhizal fungi in the soil.
The cylindrical spike grows up to 50cm in height and can carry up to 100 yellow-brown flowers that smell like honey. The sepals and upper petals are short and form a fan-shaped hood at the top of the flower. At the base is a broad, long lobe that is forked in the middle, and at the base of this lip is a shallow cup of nectar which is used to attract small insects for fertilisation.
Distribution: This species has a scattered distribution throughout the UK but is locally common in southern England and Northern Ireland. Bird’s-nest Orchids can be found in mature woodland, especially those with beech and Yew, in southern England and typically flower from early May to late June.
Identification: This distinctive orchid has two variations: early flowering and late flowering forms, which exhibit subtle differences in flower colour. This orchid is conical to cylindrical in shape and features densely packed, deep-purple flower buds. These flowers have dark purple-red sepals and pale petals, including a four lobed white lip with red-purple spots.
Early Flowering Form: Grows up to 10cm tall, with a closely packed flower spike bearing up to 50 small flowers. The sepals and upper petals form a tight, darkly coloured hood, which appears red-brown when the flowers first open and quickly fades as the bud matures. It has a long white lip with two rounded side lobes, and a bluntly forked central lobe. Early flowering forms have a strong, sweet scent and are pollinated by flies.
Late Flowering Form: Typically found between 8 and 15cm in height. Late flowering form flowers have shorter, blunter lobes and the red colouring on the hood remains strong even with maturity. The edges of the lip are usually flushed with colour, which can spread over the whole lip in some cases.
Distribution: Formerly widespread throughout the UK but has undergone declines in the north and midlands. It is now found in a few localities, mainly in southern England, on chalk and limestone grassland and meadows. Early flowering forms bloom mid May to mid June. Later flowering forms bloom late June to early August.
Identification: Greater Butterfly Orchids can grow up to 60cm in height. The plant consists of a tall spike of up to 40 greenish-white flowers in a loose cluster. The overall flower structure is similar to Lesser Butterfly Orchids and has ovate lateral sepals with a wavy edge like the wings of a butterfly. The upper sepal and petals form a broad, green-white hood and a long, translucent lip has a green tip. At the base of the stem, there are two large, shiny leaves that are blue green in colour and elliptical in shape.
Distribution: Widespread throughout the UK, but most common in southern England. Found in meadows, open scrub, grassland and ancient woodland on chalk grassland or calcareous soil. Flowers from late May to late July, where they emit a powerful scent at night and are pollinated by moths.
Identification: Up to 70cm in height, the spike is either pyramidal or cylindrical in shape and can host up to 70 flowers at a time, all various shades of pink, purple and on occasion, white.
The flowers are slightly scented and are pollinated by a range of insects but are particularly attractive to day-flying moths. They have a three lobed lip with a larger, more triangular central lobe that is marked with a pattern of dark pink spots and stripes. The lateral sepals are spreading, and dorsal sepals and upper petals form a loose hood at the top of the flower. All petals and sepals are marked with dark pink lines and dots. It has spotted, narrow basal leaves that form a rosette at ground level.
Distribution: One of the most common and widespread orchids in the UK, but is absent from much of Cornwall, Devon and northern Scotland. They can be found in a range of habitats, including woodland, dry grassland, wet meadows, marshes, man-made road verges and railway embankments. Common-spotted Orchids can be found in flower from mid-May to early August.
Identification: This species is named for the pyramid shape of its flower spike during early growth stages, before it matures into an elongated, cylindrical shape. The flower spike grows up to 60cm in height and is densely flowered with up to 100 flowers at a time. These can be pale pink, to reddish pink in colour and have a sweet vanilla-like scent. The lower lip is divided into three lobes, which can vary in shape, and the sepals and upper petals form a tight hood over the flower. Pyramidal Orchids have up to four grey-green, narrow basal leaves.
Distribution: Common and widespread in England and Wales. It can be found on grassland and sand dunes on chalk and limestone soils, and grows well on human-made habitats, including road verges and roundabouts.
Identification: These distinctive plants have a flower that resembles the body of a bumblebee – a pattern that has since lost significance in the UK, so this species relies on self-pollination.
It grows between 10-50cm in height, and each plant can develop up to seven good-sized flowers. At the base of the stem, there is a rosette of five to six grey green basal leaves – these sit at ground level and have two sheathing leaves that grow upwards on the stem. The distinctive, velvety lip has three lobes – the central section is slightly convex and the side lobes form two small humps. It is rich maroon to purple-brown in colour, with grey and pale-yellow markings. The three wing-like sepals are pink and have a central green vein. Upper petals are brown and cylindrical in shape, forming the antennae of the bee.
Distribution: Found throughout Britain, although scarce in Cornwall, north Devon and Scotland. Bee Orchids can be found on dry chalk and limestone grasslands, calcareous dunes and roadsides or waste ground. Flowers from early June to late July.
Identification: This fascinating species has evolved to resemble an insect in order to attract pollinators. Fly Orchids can grow up to 60cm in height and can bear up to 15 flowers on a spindly stem. The flower has a velvety texture and is dark purplish brown in colour with an iridescent blue band in the middle of the lip. The lip is long, with two short side lobes, and a central lobe that is notched at the bottom. At the base, there are two coloured patches that resemble eyes, with the same velvety texture. The flower has three sepals that are pointed, yellow green in colour and stiff. The thin upper petals are dark purple or brown and resemble antennae.
Fly Orchids typically have three to four dark green basal leaves, that are shiny on the surface and have blunt tips.
Distribution: Widespread throughout the UK, but populations are declining and are fairly scattered in northern England and north Wales due to habitat loss. Fly Orchids can be found in deciduous open woodland, open scrub, grassland, quarries and roadside banks on chalk and limestone soils, and flowers from May to early June.
Identification: A distinctive purple flower on a tall spike. Early Purple Orchids can grow up to 60cm in height, and are easily recognisable by their pink-purple flowers and spotted leaves. The flower spike is oval or cylindrical, carries up to fifty flowers at once on a dense cone-shaped cluster, and has darkly spotted, glossy basal leaves that form a rosette on the ground.
Their sepals spread upwards, and the lip is broad with three lobes and lightly crinkled edges. The centre of this broad lip is paler in colour, and features darker coloured spots over the surface. Upper petals and sepals form a hood at the top of the flower, which has a sweet honey-like scent, that quickly turns unpleasant (likened to tomcat urine) as the flower matures. Flowers do not produce nectar and are pollinated by a variety of bees.
Distribution: Early Purple Orchids can be found throughout the UK, with very scattered groups or complete absence in some regions due to habitat loss and agricultural management. These orchids are found mainly on chalk and limestone soils, in woodland, grassland, rocky cliffs, road verges and embankments. Flowers first appear in spring, typically from early April to early June.
Identification: Common Twayblades can be readily identified by a pair of broad, round or egg-shaped basal leaves that are flush to the ground. The hairy flower spike can grow up to 50cm in height and contains up to 100 clustered, green flowers that are likened to small people – the upper petals and sepals form a hood over a long, yellowish-green forked lip which resemble legs. They have a slightly musky scent and are pollinated by small insects including wasps, beetles and sawflies.
Distribution: Common and widely distributed throughout the UK. Common Twayblades can be found on grassland, deciduous woodland, dune slacks, road verges and chalky soils. Flowers from late April to early August.

A bird table is a great way to provide supplementary food sources to local bird species, especially during harsh winter months, and offers a delightful window into the lives of our local birdlife. This added food source can have significant positive impacts on the overall health, condition, and breeding success of bird populations in the UK, but with this support comes the responsibility of ensuring a clean and healthy feeding environment. Feeders can quickly become breeding grounds for harmful bacteria, encouraging the spread of diseases such as avian trichomoniasis and avian influenza, so it is important to understand how to keep them clean.
In this blog, we detail how to clean and maintain garden bird tables and feeders throughout the year, and highlight the importance of good hygiene for bird conservation in the UK.
Maintaining good bird table hygiene to mitigate the spread of disease is of growing importance. British birds are under significant pressure from habitat loss, land use change and increasing urbanisation across the country – and conditions like avian trichomoniasis, a contagious disease partly responsible for widespread declines of Greenfinches in the UK, can be easily spread through contaminated food dropped by infected birds. Proper bird table hygiene can not only mitigate the spread of disease, but can also minimise the attraction of pest species like mice and rats, which pose a risk to human health through the transmission of zoonotic diseases.
Disease prevention extends beyond simple cleaning – positioning bird tables away from perching or roosting areas minimizes contamination from falling debris or excess faeces, andprioritizing designs that attract smaller songbirds can also reduce the concentration of larger, messier species like pigeons. Replacing older tables, which typically have a lifespan of around five years, also ensures that damaged or difficult-to-clean surfaces don’t become persistent reservoirs for pathogens.
Daily maintenance is essential to prevent the accumulation of harmful bacteria and mould:
Dispose of any uneaten food on bird tables– seed mixes and mealworms in particular should be disposed of after 24 hours
Check over the suet balls or birdseed in your feeder to ensure that it is safe to eat
Thoroughly sweep the table surface or wipe over the feeder pegs to remove debris, droppings and loose food
Monthly
A monthly deep-clean is important to prevent disease transmission in your garden, especially during wetter, colder months:
Disassemble any removable parts for a separate, more thorough cleaning
Scrub each part with a stiff brush and a solution of soapy water or diluted bleach to eliminate harmful bacterial or fungal growth, ensuring that any cracks and crevices are thoroughly cleaned
Rinse all components with clean water to remove any residual cleaning agents
Allow the parts to air dry completely in the sun before reassembling and refilling with food
End of season
At the end of the season, a comprehensive ‘full service’ of your bird table or feeder should be undertaken:
Thoroughly inspect the table or feeder for damages and repairs – whether this be splintered wood,cracks and splits,or loose screws. Repair or replace as needed
Consider repainting or treating table wood with a wildlife-friendly, non-toxic wood preservative or paint to safeguard against weathering and decay
Ensuring your bird feeder is in a good state of repair minimises the risk of injury by garden birds and ensures that the table can be easily cleaned to minimise any bacterial or fungal growth.
Well-maintained bird tables and feeders can directly impact the health and well-being of our local avian populations. By implementing a routine of daily, monthly, and end-of-season cleaning, you can minimise the risk of disease transmission and provide a safe feeding environment for local birds.

Applications
Underwater drones, or ROUVs, provide an alternative, accessible tool for ecological and scientific research. Their applications extend far beyond observation, enabling researchers to conduct detailed ecosystem health evaluations, monitor invasive or threatened species, and perform habitat inspections – all with the capability to collect samples for off-site analysis. From assessing the source of underwater pollution, to conducting biodiversity surveys, these drones provide high-resolution imagery and real-time data, facilitating well-evidenced conservation action. Their ability to perform targeted water and physical sampling allows for detailed analysis of aquatic environments, which can reveal insights into aquatic biodiversity and ecosystem health.
Outside of its ecological applications, this technology has potential in search and rescue operations, item recovery, hull and dock inspection and energy facility inspection.

In early November, NHBS colleague Dan volunteered with Chagford Conservation Group and the Chagford Parish Council to regenerate public grounds for wildlife – find out about his volunteer work below.
When strolling through your local public green space, take a moment to consider its value—not just as a recreational space but as a haven for wildlife. Behind the trees, shrubs, and ponds lies a delicate balance that requires care. Who ensures these spaces thrive for the benefit of both people and nature?
As you dig into the depths of your mind for answers and speak to fellow locals, you’ll discover that your local wandering patch has a past, present and even the future.
My front door patch, Padley Common, in Chagford – Dartmoor, has a variety of most of the above. Deciduous woodland, grassy fields aligned with stone walls and tree banks, areas with bracken and gorse, an area thick with young trees, streams and even some boggy areas.
One cloudy but warm November morning I joined the Chagford Conservation Group to help clear an area that was taken over by young willow and silver birch growth. Reading this with conservation specs may cause a frown. Cutting trees for conservation? The purpose of this venture, commissioned by Chagford Parish Council, was to restore the grounds to more favourable conditions for butterflies. Under the direction of Devon Wildlife Trust personnel, we cleared young willow and silver birch growth from the common. These trees, if left unchecked, would outcompete light-loving wildflowers and raise water uptake, drying out the damp grasslands needed by marsh fritillaries. This species depends on devil’s-bit scabious for its larvae. Its population in England has declined by 66% since 1990. Maintaining open, flower-rich meadows not only benefits butterflies but supports a host of other pollinators and insects.
Under the direction of Devon Wildlife Trust personnel, the Chagford Conservation Group and the Chagford Parish Council volunteers rolled up their sleeves and cleared a section of the common.
The cleared trees didn’t go to waste. They were repurposed into leaky dams that were fitted into streams that run through the common. These benefit the landscape in surprising ways as they allow water to pass through but slow its flow, reducing erosion and flood risk downstream. By creating side pools and wet areas, leaky dams also provide habitat for amphibians and aquatic insects.
With three organisations involved and so much goodwill from the local community, the day’s work saw the clearing completed and a series of leaky dams constructed. It was striking to see how effectively conservation targets can be achieved when vision, organisation, and community support come together.
Next time you wander through your local patch, take a moment to imagine its potential for wildlife. What small changes could make a big difference? Remember, with the right plan and a collective effort, even a single day’s work can transform a space—creating benefits for nature and leaving a legacy for future generations to discover as they explore their local patch’s story.
February 2025 update:
Last weekend I joined a local volunteering group for some more work on the same site – clearing brambles and gorse to enable new growth. On checking the leaky dams, I was delighted to see that pools created by these were now full of frog spawn!
June 2025 update:
Butterfly Conservation have now completed a survey of Padley Common and found 3 times as many marsh fritillaries as last year. All the efforts in clearing and pulling up of tree saplings have made it much more attractive for butterflies. The weather may have had a positive effect too, but Butterfly Conservation assume the work done has made an impact.
