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! 

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)

Image by Ekaterina Chernetsova via Flickr

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)

Image by Gertjan van Noord via Flickr

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) 

A small white bird with a black head. Its legs and beak are a vibrant red and the wing tops are a light grey

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.

The NHBS Guide to Autumn and Winter Foraging

Foraging for food is an easy way to connect people of all ages with nature. Some of us may forage unknowingly while picking juicy blackberries in the summer months, and some of us may be unaware of the vast array of edibles around us throughout the year. Here we have selected a handful of items to forage through autumn and winter, highlighting where you can find them and their culinary uses.  

It is important to be certain of your identification, so if you are unsure, check all foraged foods with a professional as some plants have toxic look-alikes. Remember to forage responsibly by leaving plenty behind for wildlife and allow plants to set seed or spore for regeneration. 


Mushrooms and Fungi

Oyster Mushrooms (Pleurotus ostreatus)

Image by Sarah Ward via Flickr

Identification: With its distinctive appearance, this bracket fungus is instantly recognisable. It has an oyster-shaped cap, that can be white, cream, grey or tan in colour and measures up to 25cm across. The gills underneath can vary in thickness with age, but are generally white or cream in colour.  

Distribution: Oyster mushrooms can be found throughout the year in large numbers, but they are most commonly seen in the winter months growing on deciduous hardwoods, such as beech.  

Culinary Uses: Oyster mushrooms have a meaty texture and a mild, nutty flavour. They have a diversity of culinary applications and are often used to substitute meat due to their fleshy texture. They can be sauteed, stir fried, grilled and roasted, or used as an ingredient in soups, stews, risottos and pasta.  

Did you know? Oyster Mushrooms are carnivorous and can digest nematodes (microscopic, unsegmented worms).  

 

Velvet Shank Mushroom (Flammulina velutipes)

Image by Peter O’Connor via Flickr

Identification: Growing in overlapping tiers, Velvet Shank Mushroom caps can measure up to 7cm in diameter and 10cm in height. The caps are bright orange, with a pale edge and a darker area towards the middle, which interestingly becomes slimy to the touch in wet weather. The gills are broad and white, turning yellow with maturity and the stalk is fibrous and soft.  

Distribution: The dense clusters of this fungus can be found on dead and decaying broadleaved trees from late autumn to early spring. It is fairly common throughout the UK and can be found on the stumps and trunks of hardwood trees. The fungus shows a preference for elm, but can also be found on beech, oak and Hawthorn.  

Culinary Uses: Velvet Shank has a sweet, nutty flavour and a chewy texture. They are only edible once cooked, and can be used in soups, casseroles and stews, or can be preserved using oil or vinegar for use throughout the season. For improved texture, the skin and stalks should be removed during preparation. 

Did you know? Velvet Shank Mushrooms are one of few species that can be found in December because they can survive frost and being frozen solid.  

 

Beefsteak Fungus (Fistulina hepatica)

Image by Ancient Woods and Trees Project via Flickr

Identification: Also known as Ox-tongue Fungus due to its resemblance as a young fungus, this bracket fungus grows up to 25cm in diameter and 6cm in thickness. The upper surface is a deep red and it has a cream-coloured underside that is covered with small pores.  

Where/when: Beefsteak Fungus can be found from late summer to autumn and is common in broadleaved woodland. It can be spotted close to the ground on tree trunks and stumps, particularly Sweet Chestnut and oaks.  

Culinary Uses: This fungus has a marbled, rubbery texture and a slightly sour, acidic flavour. It can be eaten raw when sliced thinly but is more commonly cooked in larger chunks. During preparation, Beefsteak Fungus should be simmered for a little while to soften the flesh.  

Did you know? Beefsteak fungus will ooze a watery blood-like substance when cut. 

 

Nuts and Seeds

Chestnuts, Sweet Chestnut Tree (Castanea sativa)

Identification: Chestnuts grow on Sweet Chestnut trees; a large deciduous species which can grow up to 35m in height. It has long, toothed leaves that can grow up to 28cm in length and its flowers are long, yellow catkins. Sweet Chestnuts produce fruit cases that are covered in soft green spikes, and inside these cases are up to three shiny brown chestnuts.  

Distribution: Sweet Chestnut trees are mostly found in south-east England in woodlands, towns and gardens. The chestnuts begin to drop from October and can be found until early winter. 

Culinary Uses: Chestnuts can be baked, boiled, roasted, candied or stored in syrup. Before cooking, a cross should be scored on the bottom to prevent them from exploding. Once cooked and peeled, chestnuts can be used in cakes and stuffing and are often enjoyed as a festive treat.  

Did you know? In the UK, it is believed that Sweet Chestnut trees were introduced by the Romans as a source of flour. 

 

Walnuts, Walnut Tree (Juglans regia)

Identification: These seeds are foraged from the Walnut tree, a large, broadleaved deciduous species that can grow up to 35m in height. The bark of the Walnut is smooth and olive-brown in colour, which fades to grey as the tree matures. The pinnate leaves have up to nine pairs of leaflets, with one terminal leaflet at the end and the tree has long, yellow green coloured catkins. The brown, wrinkled walnuts can be found inside a green husk which splits as it ripens and can be picked from late autumn.  

Distribution: A common and widespread species throughout the UK, Walnut trees can be found on farmland, towns, parks and gardens.  

Culinary Uses: Walnuts are a popular snack and can be incorporated into several dishes, sweet or savoury. They can be eaten raw, roasted, fried or pickled.  

Did you know? Walnut leaves are said to smell of furniture polish when crushed.  

 

Hazelnuts, Hazel Tree (Corylus avellana)

Identification: Mature Hazel trees grow to around 12m tall and are easily identified by their leaves. They are soft to the touch, with a round shape, pointed tip and serrated edges. The flowers consist of yellow cylindrical catkins that hang in clusters from mid-February, giving way to the oval fruits which hang in groups of around four and are surrounded by leafy bracts. 

Distribution: Common and widespread across the UK, Hazel trees can be found in woods, hedgerows, parks and gardens. Hazelnuts are present from late August and are ready to harvest up to October when the husks are golden brown and begin to split. 

Culinary Uses: Once ripened in a dark, dry place, hazelnuts can be roasted or baked, and used to create stuffing, nut butters, pastry fillings and traditional festive confectionary.  

 

Plants and Trees

Stinging Nettle (Urtica dioica)

Identification: Stinging Nettles can be easily identified by their dull, serrated leaves that, along with the rest of the plant, are covered in small, stinging hairs that deliver an itchy sting when brushed. The stem is square, and the flowers are small and green, resembling catkins with no petals.  

Distribution: Stinging Nettles are common and widespread throughout the UK and can be found in woodland, grassland, hedges, roadsides and wasteland from Spring to Autumn.  

Culinary Uses: The shoots and leaves of Stinging Nettles are extremely versatile in the kitchen and can be used in soups, risotto, pesto and popular herbal teas.  

Did you know? It is thought that roman soldiers rubbed their bodies with nettles to keep warm and promote good circulation.  

 

Hairy Bittercress (Cardamine hirsuta)

Identification: A small, annual herb in the mustard family, Hairy Bittercress grows to around 30cm in height. The compound leaves consist of small, rounded leaflets that are arranged in opposite pairs, forming a compact rosette close to the ground. The small, white flowers have four petals forming a cross shape and are around 1cm in diameter. The entire plant is covered in small, pale hairs.  

Distribution: Common and widespread year-round, Hairy Bittercress can readily be found in the cracks in pavements, patios, walls and gardens. It prefers damp, shady areas but may also be found in heathland, coastal areas and moorland.  

Culinary Uses: Although considered a weed, Hairy Bittercress has a wide range of culinary uses. It has a tangy, peppery flavour and can be used in salads, soups, salsa, or pesto, and can even be used to substitute cress and rocket. Picking leaves from the middle of the rosette is advised for the best flavour.  

 

Scots Pine (Pinus sylvestris)

Identification: Growing up to 35m in height, Scots Pine trees are easily recognised by their straight, unbranched trunk and conical crown. The needles are grey green in colour and are arranged in twisted, bunched pairs with orange scented flowers that mature into green cones.   

Distribution: Scots Pine are common and widespread throughout the northern hemisphere. Wild trees can be found in abundance in the Caledonian Pine Forest of Scotland and are widely planted elsewhere in the UK.  

Culinary Uses: Scots Pine needles can be harvested throughout the year to make pestos, soups and stews. Young pine needles can be used to make tea or can be infused with oils to harness their citrusy, lemony flavour. 

 

Fruits and Berries

Rosehips, Wild Dog Rose (Rosa canine)

Identification: Rosehips come from the wild Dog Rose; a thorny, scrambling shrub with pale pink flowers. The flowers have five petals and yellow stamens that give rise to oval shaped, green seed pods known as rosehips. These eventually ripen to a vibrant red and contain numerous small seeds covered in irritating hairs.  

Distribution: Dog Rose is common and widespread across the UK where it can be found year-round in hedgerows and woodland fringes. Rosehips appear around September after the rose has flowered, and last throughout the winter – they are ready to be picked when they feel plump and soft  

Culinary Uses: Rosehips can be used to make jams, jellies and syrup for cordials, tea and desserts. Rosehip tea is commonly brewed with citrus fruits, lemongrass, dried fruit and honey for a vitamin C rich drink. These berries have also been used to infuse vinegars for a fragrant salad dressing. Rosehips cannot be eaten raw and must be cooked before ingestion. The irritating hairs around the seeds should also be removed during preparation. 

 

Sloes, Blackthorn (Prunus spinosa) 

A branch with many bunches of purple blue berries

Identification: Sloes grow on the Blackthorn tree, a black-barked scrub that grows to around 7 metres. Blackthorn has spiny, black-purple twigs and oval-shaped, toothed leaves which have pointed tips and a tapered base. Blackthorn trees produce small, white blossom in early spring, before the leaves develop. The sloes, which are the smallest fruit in the plum family, are blue-black berries around 1cm across. They can be picked from September to December and are known for their acidic taste. 

Distribution: Blackthorn can be found in abundance in woodland, field edges and hedges throughout the UK.  

Culinary Uses: It is recommended to pick sloes after the first frost for the best flavour, however this can be replicated by freezing and thawing the sloes at home. The tart flavour of sloe berries is favoured for preserves, wine and sloe gin. Historically, sloes have also been used to make tonics and syrups as health remedies.  

 

Elderberries, Elder Tree (Sambucus nigra)

Identification: The Elder tree is a deciduous species which can grow up to six metres in height and is identifiable by its toothed, oval leaves. Each compound leaf has up to seven leaflets, arranged in opposite pairs with a single leaflet at the top. The flowers of this tree, elderflowers, bloom between May and June. Clusters of white, five-petalled flowers appear with prominent yellow stamens, and umbels of dark elderberries form in late August. 

Distribution: Elder trees can be found growing in a variety of conditions year-round, and are largely non-selective with their environment, which can include hedgerows, woodland, scrubland, grassland and urban green spaces.   

Culinary Uses: Packed full of antioxidants and vitamins, elderberries have been used for centuries to support human health. These dark berries can be used to make wine, syrups, jams, cordials and can be incorporated into cakes and crumbles. Please note that elderberries should always be cooked before eating to neutralise cyanide compounds present within the fruit.

Beyond the Cap: Is Mycology only about Mushrooms?

For many people, the mention of mushrooms conjures up images of stroganoff, druids, or damp housing. However, for those of us who are mycologically inclined, a vast kingdom of species, ecological interactions, and secondary metabolites awaits to boggle the mind. Fungi are everywhere, circulating through the air as spores, forming networks below our feet, and even influencing popular culture. But what is mycology?

The History of Mycology 

Originating from the Greek language, mycology translates to the study of fungus. The term was first coined in the early 19th century, but the study of fungi goes much further back. The Greeks pioneered written fungal observations, initially through records of poisonings. They were also the first to attempt to classify mushrooms (fungi), albeit as plants with missing parts, a narrative that persisted until the late 1960s when the fungal kingdom was first described. 

Since the Greeks, theories about fungi origins ebbed and flowed throughout written history. From a modern taxonomic standpoint, Linnaeus (the father of modern taxonomy who formalised binomial nomenclature) and his contemporaries were integral to mycology, describing groups (genera) that still exist today, such as Boletus and Agaricus – though these have been heavily adapted from the original classifications. However, at this time, mushrooms were still classified as plants within the subcategory of ‘Cryptogamia’, due to the lack of apparent sexual organs, a similar grouping to that of the Greeks. But is mycology solely concerned with mushrooms, colloquially known as toadstools, the enigmatic, ephemeral fruits of fungal species? 

The short answer is no. Once thought to be asexual plants, mushrooms are actually the reproductive structures of fungal species that form networks of organic strands called hyphae, collectively known as mycelium. When two sexually compatible hyphal strands from the same species meet, they twist and writhe, forming a knot. It is from this mycelial joint enterprise that the mushroom fruits, hence the term ‘fruiting bodies’.

Fungal Groups 

Boletus and Agaricus are prime examples of iconic toadstool-forming fungal genera. Once fully developed, the toadstool drops spores, either from pores (in the case of Boletus) or gills (as with Agaricus). These genera are members of Basidiomycota (the spore-droppers) that release spores to fall to the ground. The other major fungal group, Ascomycota, the spore-shooters, fire spores from specially adapted tissue into the wind. Fungi classified as Basidiomycetes do not exclusively form toadstools, there is a large variety of fruitbody formations, each with unique identifying features and characteristics. Examples include brackets, puffballs, earthstars, stinkhorns, corals, toothed fungi, jellies, rusts, and smuts. 

Ascomycetes, the spore-shooters, exhibit a similarly large variety of fruit body forms. Many ascomycete fruit bodies are considered cup fungi, such as the morel – a forager’s favourite. Cup fungi belong to the Pezizomycetes. This subgroup also contains truffles, which are prized by chefs, foodies, and mammals of various sizes. Other intriguing forms include saddle-shaped fungi, earth tongues, and club- and finger-shaped fungi.  

Ascomycete fungi are known for their propensity for parasitism and pathogenicity, such as the ever-fascinating Cordyceps (zombie ant fungus), made famous by The Last of Us, or Ergot (Claviceps Purpurea), a plant pathogen. Ergot is hallucinogenic when consumed by mammals and most famously caused a ‘dancing plague’ among villagers in the early 20th century. Some fungi do not produce hyphae and therefore do not form mycelial networks or fruit bodies. A famous example of an Ascomycete fungus that doesn’t produce spores, mushrooms, or mycelium is yeast (Saccharomyces). Yeast is unicellular and present in the air and has had a dramatic impact on human societies via bread and beer, a winning combination.

Lichens 

Lichens represent a fascinating intersection of biology, ecology, and mycology. These composite organisms are the result of a symbiotic partnership between a primary photo-biont, typically algae or cyanobacteria, and a fungal host. The photo-biont contributes photosynthetic sugars, while the fungus creates a stable environment for the photo-biont to thrive. This mutualistic relationship is an ingenious ecological strategy that allows both partners to survive in diverse and often extreme environments. Interestingly, as mycologists delve deeper into lichen biology, more complex partnerships are being discovered. Notably, 98% of the fungi associated with lichens belong to the ascomycetes, the group of spore-shooting fungi, and almost half of all ascomycetes participate in lichen formation.

Slime Moulds 

Let’s touch on slime moulds, another group commonly mistaken for fungi. These soil-dwelling amoeba, originally described as ‘fast-growing fungus’, were integrated into fungal evolutionary history until the 1970s. Slime moulds share similarities with fungi in their lifecycles and ecological niches, but despite their name and popular belief, they belong to a different kingdom altogether – the protozoan kingdom. It’s easy to see why they were once considered members of the fungal kingdom, as they ‘fruit’ under similar conditions and are often found on rotten substrates in damp forests.

The often-overlooked fungal kingdom has been a key component to the development of life on earth and is often cited as one of the drivers for terrestrial evolution. Alongside its significance in evolutionary history, this unique kingdom has also benefitted humans for millennia and is expected to play a vital role in future healthcare, farming and food security. In addition to these significant contributions to civilisation, fungi are a delight to stumble across in the wild and are an object of beauty and wonder for many. Whether you are a seasoned mycologist, budding enthusiast or a complete beginner, fungi are bound to captivate you with their peculiarities so why not head out this autumn, explore the forest floor, and see what you can find?

Wild and Wonderful: A Spotlight on Endangered Mammals in Britain and Ireland

This blog focusses on forgotten species; those that are extinct, endangered or just urban, small and under-recorded. With climate change, habitat loss and invasive species threatening our native mammals, highlighting their importance is vital in driving their conservation, so we have chosen to spotlight three of the UK’s endangered mammals, discussing their biology and characteristics, current conservation initiatives and what the future might look like for these animals.  


Eurasian Beaver (Castor fiber)

Habitat: Freshwater, particularly streams and rivers near woodland. 

Diet: Aquatic plants and grasses during warmer months, tree bark and shoots during winter. Preference for willow, Aspen, Alder and fruit trees. 

Conservation Status: Critically endangered in England, endangered in Scotland. 

Distribution: Free-range populations in the River Tay, River Otter and Knapdale, Scotland. Enclosed populations in Kent, Essex and the Forest of Dean. As of 2023, Scottish beavers have established 424 territories, housing up to 1,500 individuals. 

Breeding: Between December and April. Birth in early summer of up to six kits, sexually mature at two years old.  

Description: With distinctive orange, chisel-like teeth and a flat, scaled tail, beavers are instantly recognisable. Similar in size to a medium dog with shorter legs and a rounder body, the fur of a beaver ranges from brown to black. Once widespread in the UK, the Eurasian Beaver was historically persecuted for medicinal and cosmetic purposes. The species was hunted for fur, meat and the oil from its scent glands, resulting in extinction by the 1600’s. 

Did you know? High iron content in the enamel of their teeth gives them their distinctive orange colour. This addition provides the teeth the extra strength that is required for felling trees and eating.  

Conservation of Eurasian Beavers 

Beavers are talented ‘engineers’, able to transform wetland and freshwater environments. Through the alteration and modification of these habitats, beavers can create complex wetlands, ponds and nurture more resilient ecosystems. Their dams provide a natural filtration system for freshwater landscapes and water quality is shown to increase as it passes through dam complexes, helping to reduce diffuse pollution in the area. Through improved water storage, beaver activities can also maintain water flow to drought-ridden landscapes, increasing the habitat’s resilience to climate change related conditions.

Environments altered by beaver presence host significantly higher diversity compared to those without. Tree felling can shed more light onto aquatic areas, encouraging growth of wetland vegetation. Feeding on larger, fleshy plants can favour smaller, slow-growing species in the surrounding habitat, leading to more abundant, diverse plant communities in the long-term. Species richness and overall abundance of small mammals, amphibians and bird species are also found to be higher in areas close to beaver dams.  

After 400–500 years of local extinction, beaver reintroduction has been gathering traction in the UK.  There are a number of reintroduction projects trialling their release, including the 2009 Scottish Beaver Trial in Knapdale Forest (which introduced around a dozen beavers to over four hectares of land) and the Devon Beaver Project which introduced one family group to an enclosed area in West Devon. England’s first wild project, The River Otter Beaver Trial, was founded due to the discovery of wild beavers in the region. This 5-year project observed eight family units over 28,700ha and is seeking to demonstrate the effect of beavers on other wildlife, local landscapes, water flow, water quality and local communities. Further reintroductions across the country have established both wild and enclosed populations of this keystone species.  

Looking Forward 

Reintroduction projects across the UK have been successful. Populations are breeding successfully and have been expanding their territories. However, there is cause for concern with the potential of conflicts to arise over land management.  It is likely that, with expansion, there will be human-wildlife conflict with landowners and other stakeholders in the future. The impact of beaver activities on the environment can cause flooding of pasture, risk to crops and the felling of trees can cause harm to livestock and structures. Natural England has advised a paced approach to beaver reintroduction, minimising impacts to land use, infrastructure, livelihoods or environmental features while maximising benefits for the environment. 

 

Water Vole (Arvicola amphibius)

Habitat:  Grassy banks along slow-moving rivers, canals and streams. Marshes, reedbeds, wet moorland, wetland.  

Diet: Grass and waterside vegetation. Wetland plants in spring and summer. Roots, rhizomes, bulbs and bark in autumn and winter. Occasional invertebrates. 

Conservation Status: Endangered in England and critically endangered in Wales.  

Distribution: Found throughout mainland UK. Absent from Northern Ireland and most offshore islands. Estimated population of 132,000, range and numbers have declined by 94% from historical populations. 

Breeding:  March–October. Breed in spring, producing up to four litters a year. 

Description: A small rat-sized rodent, the Water Vole has chestnut brown hair covering their entire body and tail, with a round nose and nearly hidden ears. This semi-aquatic rodent was historically widespread until the population saw a decline, resulting in nearly 90% reductions by 1998.  

Habitat loss, degradation and fragmentation are key drivers of Water Vole declines in the UK. General infrastructure development, along with urbanisation of flood plains, have resulted in extensive loss of habitat for this species. Partnered with loss of vegetation and trampling around freshwater banks from grazing livestock, large areas of freshwater habitat are now unsuitable for voles. The unintended introduction of American Mink (Neovison vison) has also been pivotal in the collapse of Water Vole populations across the UK. Initially brought to England for fur farming, escaped mink have predated heavily on this species.  

Conservation of Water Voles 

Through grazing activities on grasses and rushes at the water’s edge, Water Voles manipulate their habitats, much like beavers but on a smaller scale. This manipulation can make space for a new community of wildflowers and grasses, attracting a host of invertebrate species to an area. As a valuable prey species, elevating Water Vole populations can support predators in the surrounding environment. Barn Owls (Tyto alba), Otters (Lutra lutra) and Pine Martens (Martes martes) are examples of native predators that would benefit from the repopulation of Water Voles.

A number of regional wildlife trusts have undertaken Water Vole recovery projects to support their repopulation in UK waterways. These typically involve recording and monitoring existing Water Vole activity, habitat enhancement, coordination of mink control, and in some cases, reintroduction of the species: 300 voles in the Yorkshire dales, over 600 in Essex, 200 in Gwent and over 1,000 individuals in Kielder Forest. The Forestry Commission has also pledged to make changes in Kielder Forest; improving the landscape by refraining from planting trees on river edges, providing much-needed habitat. In order to protect Water Vole settlement, the species is protected under the Wildlife and Countryside Act (1981), the UK Biodiversity Framework, and is listed as a priority species on the UK Biodiversity Action Plan. 

Looking Forward  

Reintroduction efforts across the UK have had mixed results. A period of growth was observed following initial releases in Nottinghamshire, which has now slowed. Overall occupancy from 2006–2018 has declined by 23%. It is thought that the continued pressure of habitat loss and mink predation is preventing populations from settling successfully. Responding to the poor establishment of Water Vole populations, recovery projects are enhancing existing freshwater habitat and building new areas to establish populations. Breeding and release sites will also be created to facilitate the successful reproduction of Water Voles in a safe environment, away from predation. In addition to habitat enhancement, more widespread mink control is also expected.  

 

Pine Marten (Martes martes)

Habitat: Native woodland, conifer plantations. 

Diet: Small mammals, carrion, birds, eggs, fruit and invertebrates. 

Conservation Status: Critically endangered in England and Wales, least concern in Scotland.  

Distribution: Widespread and relatively common in Ireland. Populations recovering in the Scottish Highlands, some isolated populations in southern Scotland.  Populations in northern England and Wales are fragmented and small. Populations estimated at 1,600–8,900 in Britain and Ireland.  

Breeding: Mating season is during the summer months. One litter per year, born in March or April. Kits are fully grown at six months and sexually mature by three years old.  

Description: Often confused with mink, Weasels or Stoats, the Pine Marten is a fellow member of the Mustelid family. Characterised by its chocolate brown fur and a distinctive, uniquely shaped light-yellow bib around the throat and chest, this elusive species has a long, bushy tail and large, rounded ears. Around the size of a domestic cat, Pine Marten are larger than both Weasels and Stoats and can be distinguished from mink by their chocolate coat.  

Pine Marten populations underwent a major decline in the 19th century due to persecution by Victorian gamekeepers on sporting estates. Extensive habitat loss and fragmentation is another factor which contributed to the decline of these species in the UK.  

Conservation of Pine Martens 

The reintroduction of Pine Martens is favoured by many across the UK. The species is valued for their natural control of the invasive, non-native Grey Squirrel (Sciurus carolinensis), which can account for up to 14% of a Pine Martens diet. This predation allows the native, endangered Red Squirrel (Sciurus vulgaris) to take hold. Eradicating competition from Grey Squirrels, and reducing the risk of the squirrel pox virus, has allowed the Red Squirrel to successfully repopulate areas around Pine Marten territory.

The Two Moors Pine Marten Project, the South East Pine Marten Restoration Project, Back From the Brink  and Martens on the Move are programmes founded to support the expansion of Pine Martens in England. A total of 35 individuals have been relocated from Scotland to the Forest of Dean and the Wye Valley, and further reintroductions are expected to take place on Exmoor and Dartmoor National Parks later this year. Other projects aim to facilitate reintroductions through the enhancement of key habitats (Martens on the Move) or to undertake surveys and monitoring to inform on species distribution (Back from the Brink).  

By 2017, around 50 Pine Martens had been relocated to woodland in mid-Wales from their original home in Scotland. The population was radio tracked throughout the first year, which monitored their movement and behaviour. The group have established a viable population, breeding every year since reintroduction.  

Looking Forward 

The future of Pine Martens in the UK is promising. Monitoring of existing projects shows successful breeding and expansion from Scotland into Northern England. It is expected that more Pine Martens will be released in the Forest of Dean, in addition to an estimated 40 individuals to be released with the Two Moors Restoration Project in autumn 2024. It is hoped that, with further expansion, populations may link with Welsh Pine Martens, boosting connectivity and genetic diversity. 

However, as populations continue to expand, there is an increasing risk of conflict. With greater human populations, greater infrastructure, and greater exposure to protected species, concerns may arise among the public. The species are known to find their way into chicken coops and pheasant pens, damaging livestock and causing conflict with local farmers. The Vincent Wildlife Trust, Natural England and NatureScot recommend sufficient Pine Marten monitoring, active engagement and open communication with stakeholders to mitigate potential conflicts before they arise.

The NHBS Guide to Summer Foraging

Foraging for food is an easy way to connect people of all ages with nature. Some of us may forage unknowingly while picking juicy blackberries in the summer months, and some of us may be unaware of the vast array of edibles around us. Here we have selected a handful of items to forage through spring and summer, highlighting where you can find them and their culinary uses.  

It is important to be certain of your identification, so if you are unsure, check all foraged foods with a professional because some plants have toxic look-alikes. Remember to forage responsibly by leaving plenty behind for wildlife and allowing plants to spore or set seed for regeneration.


Wild herbs

Garlic Mustard (Alliaria petiolata) 

Image by Daniel Jolivet via Flickr

Garlic Mustard, also known as Hedge Mustard or Jack-by-the-hedge, is a hairy herb in the mustard family. This plant has heart-shaped jagged leaves which emit a distinctive garlic odour when crushed, and has small, white flowers with cross-shaped petals. The species can grow up to 1m in height and can be found in woodland, hedgerows, cultivated land and on the borders of agricultural farmland. Each part of this plant is edible, but harvesting is best between March–April and July–September. Garlic mustard is best enjoyed before flower stalks develop, as this can create a bitter taste. The roots of this plant can be used as a substitute for pepper and horseradish and is said to taste like wasabi. The leaves have a garlicky flavour, and can be used as a replacement for traditional, store-bought garlic.  

 

Wild Garlic (Allium ursinum)

Wild Garlic (also called ramsons, bear garlic or broad-leaved garlic) is easily identified by its distinctive fragrance. When walking through areas of Wild Garlic, which are often found in large groups, you may catch a whiff of their characteristic garlic smell in the air. These areas are typically damp, shady woodland and can often be found with bluebells close by, as the pair have similar growing conditions. This plant can be seen from late winter till the end of spring, with flowers appearing in April/May. It has distinctive white, star-shaped flowers that grow in clusters. Their leaves are elongated, and when crushed release a pungent smell.  

With a milder taste than shop-bought garlic, this plant is suitable for use in pastas, pesto’s and soups and can be infused into oils and vinegars. Only the flowers and leaves are edible, so it is best to leave the root to allow for regrowth – it is also worth noting that younger leaves are better for cooking, as older leaves can create bitter flavours. This plant can be confused with the poisonous Lily-of-the-valley, so it is best to smell the leaves before consuming them – alternatives will not have a distinctive garlic smell.  

 

Wildflowers 

Elderflower (Sambucus nigra) 

Image by Kent Wang via Flickr

The Black Elder tree, a deciduous species, can grow to six metres in height and is identified by toothed, oval leaves. Each compound leaf has up to seven leaflets, arranged in opposite pairs with a single leaflet at the top. The flowers of this tree, elderflowers, bloom between May and June. Clusters of white, five-petalled flowers appear with prominent yellow stamens, and umbels of dark berries form in late August. Elderflowers can be found growing in a variety of conditions, and are largely non-selective with their environment, which can include hedgerows, woodland, scrubland, grassland and urban green spaces. Elderflowers have a long tradition of culinary use in the UK, using both berries and flowers for different purposes. Preserves, cordials, gins and puddings are all common uses of elderflower. The flowers can be eaten raw, but berries must be cooked before use. Elderflowers have a sweet and zesty taste and an aroma which is slightly lemony.  

 

Dandelion (Taraxacum officinale 

Image by Jonas Lowgren via Flickr

Although there are around 250 species of dandelion, here we refer to them collectively as they are difficult to distinguish from one another.  

An instantly recognisable British wildflower, the dandelion features a bright yellow composite flower crown on a bed of large, jagged leaves. These species are very common and widespread, popping up almost everywhere from parks and gardens to roadsides and meadows. The roots, leaves, flowers and buds of the dandelion can be used for food and can be harvested from early spring to late autumn. The roots can be used as a coffee substitute and are famously used in the Dandelion-and-Burdock drink. Leaves can be added to salads and the dandelion flowers are often used in cakes. You can also make beer from the entire plant.  

 

Fruit and berries 

Wild Strawberry (Fragaria vesca)  

Image by Michael Figiel via Flickr

A hairy, perennial herb in the rose family, the Wild Strawberry can be found from May to August. The species is indiscriminate of their growing environment and can be found in a wide range of areas – it is found naturally growing in woodlands, hillsides, meadows, hedgerows and urban green spaces. Wild Strawberries can be identified by serrated, trifoliate (three leaflets) leaves and white, five-petalled flowers with a yellow centre. The berries of a Wild Strawberry appear similar to that of commercial strawberries but are generally smaller and rougher. These edible berries can be foraged from June onwards to make teas, cordials and puddings or can be infused into vinegars and sauces. With a sweet and juicy taste, these fruits can also be used as garnishes or used in salads.  

 

Bramble (Rubus fruticosus) 

Image by Dwight Sipler via Flickr

A sure sign that summer has arrived, the Bramble is an iconic British summertime plant. This perennial shrub can be found up to 3m in height, featuring thorny stems which turn red with age and dark, jagged leaves. Come spring, a Bramble bush will have small groups of white or pale pink flowers with five petals. The fruit of this plant will appear up until autumn, with distinctive black, shiny berries. Ripening from green to purple-black, blackberries have a sweet, tart flavour. They are widespread in the UK and can be found in many habitats including woodland, hedges, fields and urban spaces. It is advised to pick blackberries away from busy roadways and paths to avoid pollutants and other contaminants. Picking from the upper half of the bush is also advised to avoid dog mess. The blackberry is a versatile fruit, with diverse culinary uses. It is commonly used to make jams, jellies and preserves but can also be used to make cordials and fruity teas.  

 

Mushrooms  

Chicken of the Woods (Laetiporus sulphureus)

Image by Doug Bowman via Flickr

Laetiporus sulphureus, named Chicken of the Woods, is a thick bracket fungus common in the UK. This fungus has bright yellow-orange clusters that fade to cream with age. The average cap can grow to around 45cm in width and is often found growing on the side of trees in broadleaf habitat between June and November. It is mainly found on oak trees, but can also be found on Yews, cherries, Sweet Chestnut and willow. It should be noted that if the fungus is found growing on Yews, or other poisonous trees, the fungus can cause sickness in humans. The firm texture of this fungus makes it a favorable alternative to chicken in vegetarian dishes, as the name suggests. It is often substituted in stews, stir fries, and marinated on skewers. When foraging, it is best to eat younger specimens to avoid a hard, leathery texture associated with older fungi. 

 

Giant Puffball (Calvatia gigantea) 

Image by Maja Dumat via Flickr

Giant Puffballs are an astonishing sight when found in the wild. Their distinctive white, spherical silhouette can reach up to 90cm in diameter. This fungus has a soft, spongy texture inside, and a thick, velvety texture on the surface. A stemless variety, this plant is found directly on the ground and is often found in small clusters or ‘fairy rings’. As the fungus ages, it becomes browner in colour, compared to the firm, white flesh of young specimens. Giant Puffballs can be found in meadows, open pasture and woodland from July to September. They are widespread in the UK but are localised in habitat. This fungus is popular with vegetarian dishes – its firm, thick texture makes it a great substitute for chicken. It is often pan fried like steak, roasted or breaded and fried.

The NHBS Guide to UK Common Garden Beetles

Beetles are insects that form the order Coleoptera, meaning ‘sheath-winged’. They get their name from the adaptation of their front wings which have formed tough protective cases called elytra.  This gives them an armour-like appearance while protecting the delicate wings underneath.  

As one of the most diverse groups across the world, there are over 400,000 species – more than 4,000 of these can be found in the UK. In this post we will look at some of Britain’s beetles, detailing their key features and where to find them.  


 Rose Chafer (Cetonia aurata 

Rose Chafer by Hedera Baltica via Flickr

Conservation status: Common 

Distribution: Widespread across the UK, but scarce in number. Most common in southern England. 

Identification: This large beetle is instantly recognisable by its iridescent emerald green carapace. Up to 2cm long, this broad beetle will often have white streaks across its wing case, which can occasionally appear purple or bronze in colour. The underside is covered in fine, pale hairs and there is an obvious ‘V’ shape on its back where the wing cases meet. 

Where to find them: Grassland, woodland edges, scrub and farmland. Rose Chafers can also be found in towns and gardens, where they are considered a pest. You can find them between May and October when they can be spotted in sunny weather.  

  

Cock Chafer (Melolontha melolontha) 

Image by Frank Vassen via Flickr

Conservation status: Common 

Distribution: Widely distributed across the UK, more common in the south of England. 

Identification: The UK’s largest scarab beetle, the Cock Chafer can grow up to 4cm in length. It has rusty brown wing cases with a black body and brown legs. Its underside is covered in fine, pale hairs and it has a pointed tail. It has distinctively large, fan-like antennae that can be used to distinguish the sex – males have seven feathers and females have six. 

Where to find them: Meadows, farmland, grassland, woodland, heath and moorland, and gardens from April to July. These insects are mostly seen after sunset, where they can be found near streetlights and bright windows.  

 

Stag Beetle (Lucanus cervus)

Conservation status: A globally threatened species, the Stag Beetle is listed as a priority species in Schedule 5 of the Wildlife and Countryside Act 1981.  

Distribution: Nationally scarce. This species is mainly found in south-east England. It is most abundant in the Thames Valley and Hampshire and is locally common in some areas of the south-west.  

Identification: A spectacular insect, the Stag Beetle is recognised for its antler-like mandibles. Males can grow up to 8cm, while the females grow to 5cm and have smaller mandibles. Both have a shiny black head, thorax and legs with chestnut-coloured wing cases.  

Where to find them: They can be found from mid-May to late July in woodland, hedgerows, parks and gardens. Although usually found on the ground, males can be seen in flight during sunset on hot summer evenings.  

 

Lesser Stag Beetle (Dorcus paralellapipidus) 

Image by Guy-F via Flickr

Conservation status: Common 

Distribution: Found throughout England and Wales. 

Identification: Smaller than their threatened cousins, the Lesser Stag Beetle grows up to 3cm in length and can be distinguished by smaller mandibles and knobbed antennae. Although similar in shape and colour, this species has a broad head and matt black wing cases.  

Where to find them: Hedgerows, woods, farmland, grassland, towns and gardens from May to September. They can often be found basking in the sun on tree trunks and can be seen flying near bright lights at night. 

 

Rosemary Beetle (Chrysolina americana) 

Image by Katja Schulz via Flickr

Conservation status: Common 

Distribution: Widespread in the UK, particularly in south-west England. Distribution is patchier in Wales, Scotland and Northern Ireland.  

Identification: A small, shiny beetle growing up to 1cm in length, the Rosemary Beetle is a striking metallic green with orange and purple stripes. The head and thorax are mostly green with some red markings, and the legs are a brown-red.  

Where to find them: Rosemary Beetles are found year-round but are commonly spotted between April and September. The species is closely associated with Lavender, Thyme and Rosemary. 

 

Wasp Beetle (Clytus arietis) 

Image by Frank Vassen via Flickr

Conservation status: Common 

Distribution: Widespread across the UK, less common in Scotland.  

Identification: A narrow-bodied longhorn beetle, this species has a long, black body with yellow horizontal stripes. The Wasp Beetle has short brown antennae and brown legs. 

Where to find them: Wasp Beetles can be found in farmland, woodland, hedgerows, parks and gardens between April and July.  

 

Red Soldier Beetle (Rhagonycha fulva) 

Image by Hedera Baltica via Flickr

Conservation status: Common 

Distribution: Widespread in the UK. 

Identification: Growing up to 1cm in length, the Red Soldier Beetle is small and narrow. It has a rectangular body that is a vibrant orange red with black tips to the wing cases. Their orange legs are tipped with black feet and they have long antennae.  

Where to find them: This species can be found from June to August, usually on open-structured flowers such as daisies and Cow Parsley, in grasslands, hedgerows, woodland, parks and gardens.  

 

Red-headed Cardinal Beetle (Pyrochroa serraticornis) 

Image by Frank Vassen via Flickr

Conservation status: Common 

Distribution: Widespread in England and Wales. 

Identification: A mid-sized beetle growing up to 2cm in length, the Red-headed Cardinal Beetle has a vibrant orange-red head and wing case. Its legs and antennae are black, the latter long and toothed.  

Where to find them: Adults can be found in woodland, hedgerows, farmland, parks and gardens from May to July. 

 

Devil’s Coach Horse Beetle (Staphylinus olens) 

Image by Frank Vassen via Flickr

Conservation status: Common 

Distribution: Widespread in the UK. 

Identification: The Devil’s Coach Horse, easily recognised by its scorpion-like stance when threatened, is a medium-sized black beetle growing up to 3cm in length. It has large, powerful jaws and a long, thick abdomen. The body is covered in fine black hairs and the wing cases are very short.   

Where to find them: Devil’s Coach Horse Beetles can be found from April to October in hedgerows, grassland, farmland and gardens. They require damp living conditions and are often found under stones and in compost heaps. 

 

Violet Ground Beetle (Carabus violaceus) 

Image by Guy-F via Flickr

Conservation status: Common 

Distribution: Widespread in the UK. 

Identification: Growing up to 3cm in length, the Violet Ground Beetle has a distinctive metallic violet colouring running along the edge of a black thorax and smooth wing cases.  

Where to find them: Violet Ground Beetles can be found from March to October in woodland, grassland, moorland and urban areas. They are frequently found under logs and stones.   

The NHBS Guide to UK Shore Crabs

A charismatic highlight of any rock-pooling session, crabs are both diverse and wonderful. Here we have a selection of the most common crabs in the UK, detailing their habitats and how to identify them. 


Velvet Swimming Crab (Necora puber) 

Image by Guy F via Flickr

Conservation status: Common, non-threatened. 

Where to find them: The species is widespread throughout the UK and can be found year-round on rocky shores at low water. They are found more frequently on sheltered shores and prefer rocky substrates.  

Shell Width: Up to 10cm.  

ID: Also known as the devil crab, the Velvet Swimming Crab has short hairs covering its body, giving the animal a velvety appearance. The crab is blue in colour, but is covered by a reddish-brown pubescence masking the overall hue – they do, however, have visible blue lines on their legs, and blue tips on their claws. The carapace is flattened and has five pointed ridges on either side of the eyes. A fast-moving and aggressive crab, it has distinctive, bright red eyes that give it its alternative name. Pincers are of equal size, and the rear legs are flattened to be used as paddles.  

 

Edible Crab (Cancer pagurus) 

Image by Guy F via Flickr

Conservation status: Common, non-threatened. 

Where to find them: Edible Crabs can be found year-round on rocky shores across the UK. The species is often found hidden under rocks and boulders but can also be found on mixed coarse ground and on muddy sand offshore.  

Shell width: 10-25cm, averaging around 15cm.  

ID: A large species, the Edible Crab is also known as the brown crab for its colour – they can be brown to reddish-brown, bearing white patches and young specimens can have a purple-brown carapace. They have a thick, oval-shaped shell with a distinctive ‘pie crust’ edge. Also recognised by the black tips to their claws.  

 

Spiny Spider Crab (Maja brachydactyla)  

Image by Guy F via Flickr

Conservation status: Common, non-threatened. 

Where to find them: Spiny Spider Crabs, also known as European spider crabs, can be found from January to December on rocky areas. They are common on the south and west coasts, but are largely absent from northern England, Scotland and the North Sea.  

Shell width: Up to 20cm. 

ID: Known to be the largest spider crab in Britain and Ireland, they are instantly recognisable for their long legs resembling a spider. They have a distinctively spiky carapace, often covered with algae giving it a hairy, green appearance. The shell has an oval shape, broader at the back and narrower at the front. It has longer, more pronounced spines on the border of the shell, and the rest is covered by smaller spines. They are mostly orange in colour, but have been found in red, yellow or brown varieties.  They have two distinct frontal spines which are sandwiched by two small eyes. The legs are covered in hair, with the first pair bearing small claws.  

 

Common Hermit Crab (Pagurus bernhardus) 

Image by Guy F via Flickr

Conservation status: Common, non-threatened. 

Where to find them: Common Hermit Crabs can be found year-round on rocky shores and sandy substrates along the UK coast. They are most easily found in rock pools at low tide, particularly after storms and turbulent weather, where they can be dislodged and are more easily visible.  

Shell width: Varies according to body size, which can measure up to 4cm in length. 

ID: The largest and most common of the 15 hermit crab species, these crabs live inside the empty shells of sea snails, commonly whelks and periwinkles. Their body is reddish-brown in colour, with a larger right pincer. Their claws are strong, and are covered in uniformly distributed granules, with two rows of larger granulations starting at the base of the claw, converging towards the middle. The species is associated with Calliactis parasitica, a sea anemone which lives on their shell in a symbiotic relationship.  

 

Shore Crab (Carcinus maenas)

Conservation status: Common, non-threatened. 

Where to find them: Shore Crabs are found year-round in rockpools. They may also be found while crabbing in shallow waters and are particularly abundant in estuaries and salt marshes.  

Shell width: Up to 9cm. 

ID: The species is slightly green in colour, but can also be found with orange and red carapaces and yellowish spots on the abdomen – varied colouration can be attributed to life cycle stages, and juvenile Shore Crabs specifically can have significant variance in colour. The broad carapace has five teeth on each side of the shell, and three scalloped lobes between the eyes.  

 

Masked Crab (Corystes cassivelaunus)

Conservation status: Common, non-threatened. 

Where to find them: A small burrowing crab, the Masked Crab can be found buried in sandy substrates on the lower shore. They are found along most of the British coastline and are particularly abundant in the south and west of the UK. 

Shell width: Up to 4cm. 

ID: Masked Crabs have an elongated oval carapace with long antennae, often the size of their body. Their colour can range from reddish brown to yellow and the lateral margin of the carapace has four distinct spines. The claws are twice the length of the carapace, although females have smaller pincers.  

 

Broad-clawed Porcelain Crab (Porcellana platycheles) 

Image by Guy F via Flickr

Conservation status: Common, non-threatened. 

Where to find them: Can be found January to December across the UK, although with sporadic distribution. They can be found under rocks and small boulders on rocky shores.  

Shell width: 1.5–1.8cm. 

ID: A small crab covered with long hairs, the Porcelain Crab can be grey to greenish-brown with an off-white underside. They have large, broad front claws that appear to be slightly flattened and two long antennae. The fifth pair of legs are smaller and often concealed, resulting in the illusion of only three pairs of walking legs. Due to its size and impressive camouflage, this species can be hard to spot.  


It can be truly fascinating to sift through rock pools, finding the weird and wonderful creatures that our environment has to offer, but it is important to remember best practices when investigating our wildlife. To look for crabs safely, approach them from behind to avoid pincers, opt for a net for safe retrieval and hold the crab firmly, without squeezing, to ensure that it does not fall whilst handling. When you are finished, remember to leave everything where you found it, replace any rocks that you may have turned over during your search and return crabs to the same body of water you found them in.  

The NHBS Guide to UK Weevil Identification

Weevils are beetles belonging to the superfamily Curculionoidea. They are generally characterised by their elongated snout, or rostrum, although this is not present in all species. The similarly named Curculionidae family exist within this superfamily and contain the “true” weevils. These true weevils have long snouts and geniculate or sharply hinged antennae that end in small clubs. There are several other families of weevil including Belidae, the primitive weevils, and Anthribidae, the fungus weevils.

As of 2012, over 600 species of weevil had been recorded in Britain. The total number of species worldwide is unknown, but estimates suggest that there are between 40,000–97,000. They can be found in a variety of habitats including gardens, parks, woodland, farmland, heathland and wetlands. They are usually found on plants but they can also be found on the ground. Some weevil species, such as vine weevils and rice weevils, feed on grains and can become an infestation inside pantries and cupboards. They aren’t harmful to humans or pets but they can cause damage to stored foods as their populations grow rapidly once they are inside containers of flour or cereals.

Identification of weevils can be difficult in the field as many species look alike to the naked eye. A hand lens, specimen pots and a good field guide can help. There are several ways to look for specimens, such as using a sweep net or beating tray or simply searching by eye. However, as weevils are very small, often less than 6mm in length, it is important to be careful when surveying.

In this post we will look at some of the most commonly found weevils in the UK, providing some key identifying features and information on similar or confusion species.

Common UK Weevils
Vine Weavil by AJC1 via Flickr (CC BY-SA 2.0)

VINE WEEVIL (Otiorhynchus sulcatus)

Distribution: Widespread throughout Britain.
What to look for: Black body mottled with small brown patches. Their elytra, the hardened forewings that serve as protective cases for the hindwings, have longitudinal grooves, or striae. Their pronotum is pebbled in texture.
Similar species: There are several dark, grooved species, and the Large Pine Weevil (Hylobius abietis) is visually similar but has orange or creamy-yellow spots resembling bands and their elytra lack defined grooves.

Green Immigrant Leaf Weevil by Tim Worfolk via Flickr (CC BY-ND 2.0)

GREEN IMMIGRANT LEAF WEEVIL (Polydrusus formosus)

Distribution: Widespread, increasing population.
What to look for: A metallic green species with round scales and pale antennae that end in a dark club. Their elytra are longitudinally striated and do not have any setae (stiff structures that resemble bristles). Older specimens may be darker in colour as their scales can wear off, showing their black under-colour. Their legs have some metallic green covering but with an orangey under-colour.
Similar species: There are several visually similar species, therefore specimens need to be examined closely. Identification in the field may be difficult.

Pea Leaf Weevil by Danny Chapman via Flickr (CC BY 2.0)

PEA LEAF WEEVIL (Sitona lineatus)

Distribution: Widespread in England and Wales.
What to look for: This is a buff species with dark longitudinal stripes that can appear dark brown or reddish. Its rostrum, or snout, is very short, unlike those of many weevil species.
Similar species: There are several similar Sitona species. Identification in the field may not be possible and dissection is often needed to confirm species.

Acorn Weevil by Lukas Large via Flickr (CC BY-SA 2.0)

ACORN WEEVIL (Curculio glandium)

Distribution: Widespread, more common in the south of Britain.
What to look for: The Acorn Weevil is a brownish-rust colour with darker markings on its elytra. It has a long, striking rostrum and a paler scutellum.
Similar species: Very similar to Curculio nucum but can be distinguished by the shape of the antennal club which is more elongated and narrow than that of C. nucum.

Nettle Weevil by Danny Chapman via Flickr (CC BY 2.0)

NETTLE WEEVIL (Phyliobius pomaceus)

Distribution: Common in England and Wales, rare in Scotland.
What to look for: A black beetle covered in metallic, bluish-green scales, which are oval. There is a prominent tooth on the front femur.
Similar species: There are multiple similar species in the Phyllobius genus. The Nettle Weevil is the only one with oval scales.

Cabbage Seed Weevil by Gilles San Martin via Flickr (CC BY-SA 2.0)

CABBAGE SEED WEEVIL (Ceutorhynchus obstrictus)

Distribution: Fairly widespread in England and Wales.
What to look for: The Cabbage Seed Weevil has a round grey body with grey legs. They are covered in small, white scales. They have a long, curved rostrum and small, bent antennae. If disturbed, this weevil will fold its rostrum and legs against its body, resembling a small pebble.
Similar species: Several other Ceutorhynchus species are very similar to C. obstrictus but they can be distinguished from some by the colour of their tarsi, the last part of the insect leg, which are black to dark-brown rather than reddish-yellow. C. Obstrictus also lacks a tooth on the hind femora.
Synonym: Ceutorhynchus assimilis, Cabbage Seedpod Weevil.

Willow Gall Weavil by Line Sabroe via Flickr (CC BY 2.0)

WILLOW GALL WEAVIL (Archarius salicivorus)

Distribution: Widespread in Britain.
What to look for: A short, black weevil with a tapered body and long snout. Its antennae are midway along the rostrum. It has a paler underside and a small pale scutellum, the small section of the exoskeleton in the middle of the back between the pronotum and the abdomen
Similar species: The Strawberry Blossom Weevil (Anthonomus rubi) is visually similar but has a less rounded appearance when viewed from above and a less barrel-shaped pronotum than the Willow Gall Weevil.

Large Pine Weavil by gbohne via Flickr (CC BY-SA 2.0)

LARGE PINE WEAVIL (Hyblobius albietis)

Distribution: Widespread.
What to look for: This is a large dark brown weevil with orange to creamy-yellow patches on its elytra, which form bands. They have black or deep red legs with a distinct tooth on the femora and at the end of the tibiae. They also have eyebrow-like patches on their head at the base of their rostrum.
Similar species: The Vine Weevil (O. Sulcatus, see above) is also dark with lighter patches, but these are brown and their elytra have more distinct striations. They also have a more distinctly ‘pebbled’ pronotum.

The NHBS Guide to UK Caterpillar Identification

Caterpillars are part of the life cycle of moths or butterflies which is known as complete metamorphosis. This life cycle includes four stages: egg, caterpillar (also known as the larval or feeding stage), pupa (the transition stage) and adult (the reproductive phase). With over 2,600 species of moth and 60 species of butterfly in the British Isles, there are a large variety of caterpillars present in our countryside.

There are several stages of caterpillar growth called instars, during which the caterpillar sheds its skin as it grows. Colouration, size and patternation can vary between these instars. Additionally, species can have different variations of caterpillars, including different colour forms. Several species are listed below, grouped by key characteristics such as colour, patternation and features.

Hairy caterpillars

There are many ecological functions of hair-like structures on caterpillars including defence and camouflage. These hairs, called setea, can be almost invisible to the naked eye, while others make them easier to see. Two types of caterpillar hair can cause harm to humans and pets: urticating, which are itchy, non-venomous hairs that can irritate the skin, and stinging hairs, which are hollow spines that have poison-secreting cells that can cause a range of health issues if they enter the skin.
