Although widely used by ecologists, trail cameras are popular with naturalists, wildlife watchers and those who are simply curious as to what creatures can be found in their gardens. They allow us to monitor the wildlife around us without impacting their natural behaviours and can capture both images and video during the day and night, with the help of infrared imaging technology. Trail cameras are constructed to endure harsh outdoor conditions, including wind, rain and temperature fluctuations, making them robust and long-wearing.
With this technology we can observe wildlife that we may not otherwise be able to see. They allow us to watch easily startled species, like deer, or those that are nocturnal, like foxes. We can also record and observe a much broader, and more natural, range of behaviours without disturbance from humans.
Our colleague, Sabine, recently captured some excellent footage on two trail cameras around her home using the Num’axes PIE1060 Solar Wi-Fi Trail Camera and the Browning Strike Force Pro1080. The cameras were placed in her orchard, which has a small stream, and were left to record for around four months and one year respectively, capturing some exciting finds.
Here’s what Sabine found:
A pair of Magpies (Pica Pica) drinking and bathing in a stream, a natural behaviour which can easily be disturbed by human presence.
The Browning detected Roe Deer (Capreolus capreolus) during both the daytime and night time around the orchard. Deer are easily startled by human presence and trail cameras allow us to observe their natural, relaxed behaviours.
Another day and night comparison of Pheasants (Phasianuscolchicus). Videos recorded by the trail camera gave us a great insight into their breeding behaviours, not commonly seen in the flesh.
A possible BankVole (Myodesglareolus) emerging from its burrow. Usually sticking to their underground burrows, or dense surrounding vegetation, a carefully placed trail camera can even be used to capture the more unusual species found across the British countryside.
A Grey Squirrel (Sciurus carolinensis) perched on a fence post to have its morning meal of a large nut. Another example of natural, undisturbed behaviour of a typically wary species.

Planet Earth may have surpassed seven of its ‘planetary boundaries’. These boundaries are described as physical or biological systems and processes that contribute to the stability of life on Earth and its supporting functions. There are nine boundaries in total, which are considered breached when the process can no longer function – these thresholds have been reached with six boundaries, and number seven, ocean acidification, is close to its threshold. Breaching this seventh boundary would reduce the efficiency of the ocean as a carbon sink, threatening marine ecosystems and global survival.
London Mayor Sadiq Khan has launched a ten-year restoration plan to clean up London’s rivers. Inspired by New York’s Oyster project, the Mayor hopes that by encouraging Eurasian Otters, Water Voles, eels and mayflies throughout the capital, water quality will subsequently improve. Khan is also investigating the reintroduction of oysters, which were historically present in the Thames, as a means of cleaning the degraded environment.
Climate Crisis
Seabirds are having to fly further to find food sources due to the melting of sea ice in Antarctica. Researchers analysed the foraging data from over 2,400 trips made by seven South Georgian seabird species from 1992 to 2023. They found that receding sea ice in the region is impacting species like Albatross and petrels as they now have to travel greater distances in search of breeding grounds and food. The data suggests that altered patterns of food availability could impact the presence of these birds in certain ecosystems however, with sea ice at a record lows, further research is needed to better evaluate the long-term impacts on seabirds.
Young coral colonies bred using IVF technology have survived a record marine heatwave. These cultivated colonies were planted onto multiple reefs in the US and the Caribbean to restore degraded habitats in the region. Last year, the Caribbean experienced a mass bleaching event which resulted in significant losses of the reef– only 25% of older corals survived, however over 90% of cultivated corals remained healthy after the event, and researchers are hopeful that this technique may provide coral species with a greater chance of adapting to heat stresses over time.
Wildlife
The EU has made the first move toward legalising wolf culls. The proposal was put forward by the European Commission late last year, and this month member governments, including Germany and France, have voted in favour to downgrade the ‘strictly protected’ status of the Eurasian Wolf to ‘protected’ under the Bern Convention 1979. This amendment would allow the EU to revise the Habitats Directive to further ease the protection of the species, which currently permits culls only with specific authorisation in extenuating circumstances.
Butterfly Conservation have announced a ‘butterfly emergency’. This year’s Big Butterfly Count recorded the lowest ever numbers since the initiative began 14 years ago, with an average of seven butterflies per count, compared to last year’s twelve. Partially due to a wetter-than-average spring, late summer and a long-term downward trend, the results indicate a significant decline in British butterflies and day-flying moths. Butterfly Conservation has responded by urging the government to ban neonicotinoid pesticides harming these indicator species for good.
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?
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’.
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 generaare 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(ClavicepsPurpurea), 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 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.
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 keycomponent to the development of life on earth andis 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 andis 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?

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 endangeredmammals, discussing their biology and characteristics, current conservation initiatives and what the future might look like for these animals.
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 observedeight 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.
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.
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.
Each year, Butterfly Conservation urges the public to venture outdoors and record their local lepidoptera populations with the Big Butterfly Count – a UK-wide survey aiming to assess the health of butterflies and day-flying moths. The count involves recording the number and species of butterflies in a chosen area for fifteen minutes and uploading results to their official website.
There are around 130 day-flying macro moths and 59 species of butterfly in the UK. These highly sensitive animals are key indicators of environmental health and play a crucial role in pollination across the country. The latest State of the UK Butterflies report, an assessment on British butterflies, found that the group has declined by 80% since the 1970s. The Big Butterfly Count allows the health and trends of these species to be assessed, improving our understanding of their conservation and threats.
This year’s count took place between Friday 12th July and Sunday 4th August, and the results from nationwide counts can be found on Butterfly Conservation’s interactive map. Over 140,000 counts were taken during this time, recording nearly 1,000,000 butterflies. Gatekeeper (Pyronia tithonus), Meadow Brown (Maniola jurtina), Large White (Pieris brassicae), Small White (Pieris rapae) and Peacock (Aglais io) butterflies were the most recorded species across all data points, accounting for over 670,000 sightings.
This years count revealed the lowest numbers on record, and has led to the announcement of a nationwide ‘butterfly emergency’. On average, seven butterflies and day-flying moths were seen per count, half of last years average. This years count observed significant downward trends in the group, with around 81% of species showing declines, and 600,000 less butterflies recorded than last year (which equates to around a third of 2023’s total observations). 9,000 counts did not record any butterflies, which is the highest number recorded in the history of the count.
We participated in the Big Butterfly Count this year, and are excited to share our results below.
The National Trust has reached a significant nature target a year early. The charity strived to restore 25,000 hectares of crucial habitat across the UK by 2025, including peatland, woodland, wetland, meadow and saltmarsh, and succeeded in doing so in August this year. The restoration comes as a response to climate change and national conservation targets and seeks to expand meadows and woodland to create a connected network for wildlife.
Eighty Water Voles have been released to restore ancient landscapes in Cornwall. Considered ‘ecosystem engineers’ these mammals are known to positively impact soil health and plant diversity through grazing and enhanced nutrient transportation. The voles were released along the River Fowey to improve the surrounding wetland habitat created in 2022.Afurther 120 have been released near Megavissey, and more releases are planned for spring next year.
Three years of restoration work have seen the return of endangered birds in Hertfordshire.Work has come to a close on the Ashridge Estate, the largest woodland maintained by the National Trust – over 24 hectares have been restored by clearing dense areas of plantation, which has allowed more light to reach the ground through the canopy. Greater access to sunlight has improved biodiversity and the availability of food sources, andthe clearing will provide suitable conditions for many breeding birds, including Spotted Flycatchers which have been spotted on the estate after several years of absence.
Conservation
Conservationists are relocating Florida’s Queen Conches in a bid to support theirreproduction. This iconic mollusc has undergone significant declinesin recent years, accelerated by increasing ocean temperaturescausing lethargy and infertility for individuals residing in warmer, shallow waters. By relocating these gastropods to deeper, colder waters, researchers are providing new mating opportunities in a more suitable environment. Listed as threatened under the Endangered Species Act, this project is helping to ease reproductive pressures on this species.
In August, the UK government announced a goal to end all badger culls by the end of this parliamentary run. The newswas announced as part of a new scientifically–informed and evidence-based eradication strategy for bovine tuberculosis, which hopes to eradicate the disease by 2038. In the past decade, over 230,000 badgers and 278,000 cattle have been slaughtered, costing the taxpayer over £100m each year. Badgers will instead be vaccinated and released, and a dedicated task force will be formed to ramp up vaccination rates.
Wildlife
Five species of seabird have been added to the UK 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, followingpopulation declines due to a number ofpressures including climate change, habitat lossand unsustainable fishing. Over 30% of all British birds are currently on the list including Kittiwakes, Puffins and Arctic Skuas, among others.
Researchers have found promise in the medicinal plants used by critically endangered Western Lowland Gorillas in Gabon. The group studied the tropical plants eaten by gorillas in Moukalaba Doudou National Park and found four trees also used by localhealers. They are high in antioxidants and antimicrobials, and one tree is a promising candidate for tackling superbugs. All four species (Fromager trees, Fig Tree, African Teak and Giant Yellow Mulberry) show activity against a resistant strain of E. coliand contain chemicals with medicinal effects useful for treating a range of ailments.
Here in the UK, we have 11 species of grasshopper and 23 species of cricket (around ten of these being bush-crickets), both subfamilies belonging to the order Orthoptera. Although similar in appearance, the two can be separated by their antennae – grasshoppers have short, stout appendages and bush-crickets have longer, thinner antennae. Bush-crickets also have a larger body size than grasshoppers, growing up to 5cm in length, and females have a distinctive ovipositor used to lay eggs.
Here, we look at a few species of grasshoppers and bush-crickets found in the UK, detailing ways to ID them and where they can be found.
ID Notes: Up to 2.5cm in length. This grasshopper is usually a mottled brown colour, but can vary from brown to grey, orange and purple. It has barring on the sides, and a very hairy underside which is the most straightforward way to identify this species. It is winged and able to fly. Their song consists of short, single chirrups repeated at short intervals.
Distribution: Common and widespread throughout Britain. Common Field Grasshoppers can be seen from May to October on short vegetation in dry, warm days. They can be found in grassy areas including farmland, grassland, heathland, moorland, towns and gardens.
ID Notes: Up to 2.3cm in length. Meadow Grasshoppers are usually green in colour, with some individuals brown or pink-purple coloured (pictured above). The wings are often brown and are long in males, whereas female wings are short and do not reach the end of the abdomen. This species has distinctive black knees and a dark brown stripe running across the flank to the eye. They are similar in appearance to Common Field Grasshoppers, but lack a hairy underside, which can be used to distinguish them from one another. Their song is a burst of around ten chirrups, making a ‘rrr’ sound.
Distribution: Common and widespread throughout Britain. Meadow Grasshoppers can be seen from April to October in damp pastures with long grass. They can also be found in meadows, grassland, heathland and moorland.
Common Green Grasshopper (Omocestus viridulus)
Image by Billy Lindblom via Flickr
ID Notes: Up to 2.3cm in length. As the name suggests, this species is mostly green in colour, but males can also be olive brown. Lines on the shoulders are incurved and white or cream in colour. Common Green Grasshoppers are winged and can fly, but their wings do not exceed the body’s length. They produce a long, loud ticking song which can last for 20 seconds or more and is reminiscent of a fast-paced freewheeling bicycle.
Distribution: Common and widespread throughout Britain, although a little patchier in the lowlands. This species appears early in spring and can be seen from April to September. It can be found in coarse, moist grass in meadows, woodland rides, hillside pastures and farmland.
ID Notes: Up to 2cm in length. This small grasshopper is most easily identified by its antennae – males’ are club-tipped, and females’ have a thickened tip. The body has several colour variations including green, brown, grey and orange. Their song is a repetitive ‘zrr’ ‘zrr’ sound lasting around ten seconds before stopping abruptly.
Distribution: Widely distributed across the UK, but uncommon. Mottled Grasshoppers can be found from April to October in areas of dry, short grass with access to rocks or bare ground, including grasslands, heathland and old quarries.
ID Notes: Up to 1.7cm in length. This species is the UK’s only native, arboreal cricket. It has a slender, lime green body with a yellow-orange or brown strip running along its back. Both sexes are fully winged, with wings reaching the end of the abdomen. Females have a long, upturned ovipositor and males have a pair of shorter, rounded claspers. The males do not produce a song, but instead drum their hind legs on nearby leaves.
Distribution: Common, found in England and Wales. The Oak Bush Cricket is common in the midlands and the south but is absent further north. It can be found in the canopy of mature trees in woods, hedges, garden shrubs and other deciduous trees from June to November.
ID Notes: Up to 2.1cm in length. This species is typically reddish to dark brown, with occasional yellow green through the abdomen and a paler area along the top of the thorax. It has very small forewings and long, hair-like antennae. Females have a large, upcurved ovipositor.
Distribution: Fairly common in central and southern England and Wales, where it can be found in woodland, hedgerows, grassland, farmland, towns and gardens. It can often be spotted in large numbers around bramble patches, where they are basking in the sun.
Roesel’s Bush Cricket (Metrioptera roeselii)
Image by Charlie Jackson via Flickr
ID Notes: A short-winged and usually flightless species, Roesel’s Bush Crickets are typically dark brown or yellow in colour, sometimes tinged green. They have a green face, slightly orange legs and a cream-coloured margin to their thorax, with two or three yellow spots on the side. Their monotonous song is recognisable for its long, mechanical sound.
Distribution: Common, found mostly in the southeast of the UK, but currently expanding its range north and west. This species can be found from June to October in rough grassland, scrub, salt marshes and damp meadows.
ID Notes: This large bush-cricket can easily be distinguished by its size, growing up to 7cm long. It is a vibrant green with an orange-brown stripe running the length of its back. Their wings are typically longer than the abdomen, and females have a long, downward curved ovipositor. This species has a loud, long song which sounds like a high-pitched sewing machine running continuously.
Distribution: Common throughout south England and Wales. It can be found from May to October in scrub, woodland, grassland and heathland, with a preference for light, dry soils.

If you look under logs, stones or through piles of leaf litter, you may find a Myriapod (a type of arthropod with many legs, related to insects and spiders). Although these misunderstood animals may strike fear in some, these invertebrates play a vital role in maintaining our ecosystems. One of their main roles lies in nutrient cycling, where they feed on organic matter and detritus, breaking materials down into a simpler form and thus releasing nutrition back into the soil. They also play an important role, both as predators and prey, in the ecosystem’s food chain and are often celebrated for their effectiveness as a natural biocontrol agent.
The UK has more than 50 species of centipede. This group are generally carnivorous and have around fifteen pairs of legs, with one pair present on each body segment. They have large forcipules, a pair of pincer-like, modified front legs that are used to inject venom into their prey. There are around 65 species of millipede in the UK, which can be distinguished by their shorter, more clubbed antennae, the absence of forcipules and their tendency to have two pairs of legs on most body segments.
Here, we look at a few species of centipede and millipede that can be found in the UK, detailing ways to ID them and where they can be found.
ID Notes: Also known as the Brown Centipede, Lithobius forficatus is one the largest centipede species in the UK, growing up to 3cm in length. They have long, thin segmented bodies that are a reddish-chestnut brown colour. Each segment has one pair of legs, with 15 pairs in total. They have long antennae and an elongated pair of back legs, giving the illusion of a second pair of antennae at the rear of the body. This species is best identified by thorned projections on the outer edges of the 9th, 11th and 13th segments.
Distribution: Very common and widespread across the UK. This species can be found year-round but is most numerous in spring and autumn. They can be found in a variety of habitats, including woodland, grassland and gardens, and will spend most of the day nesting in soil or sheltered areas under stones, bark or dead wood before emerging at night to hunt for prey.
ID Notes: Similar in colour to the Common Centipede, Lithobius microps is a ground-dwelling species that is usually chestnut brown in colour, although red and orange varieties can also be found. It is much smaller than its common cousin, reaching around 1cm in length, and its 15 pairs of legs are slightly shorter and paler than those of the Common Centipede.
Distribution: Fairly common in the south of Britain. This fast-moving species can be found year-round in gardens and bare soil in rotting wood and under rocks and stones.
ID Notes: Measuring up to 3cm in length, this small, yellow-brown centipede is easily distinguished by the banding on its legs – these alternate pale and dark, are usually brown in colour and are more obvious on the rear pairs. It has a dark band running centrally along its back and much larger jaws when compared to other Lithobius species.
Distribution: Widespread and common in the UK. It can be found year-round living under stones and decaying plant matter during the day, and is commonly found in garden compost heaps.
ID Notes: This millipede grows to around 2.5cm in length, with a width of 4mm. It has a long, flat body with around 20 body segments, each containing between one and two pairs of legs. It is orange-brown in colour and has numerous off-white coloured legs.
Distribution: Widespread and common in the UK. They can be found in almost any environment in which millipedes occur, with frequent sightings in woodland under dead wood and leaf litter.
ID Notes: Up to 3cm in length, this species is one of the largest millipedes found in Britain. It is thick and cylindrical in shape, usually dark brown to black in colour. It has orange coloured stripes running the length of its body on its back, but these can sometimes appear as a series of orange patches.
Distribution: Common and widespread throughout Britain and Ireland. The Striped Millipede can be found year-round in meadows, fields and woodland under leaf litter and logs. It is also known to climb on walls and trees to feed on algae and can be found during the day.
ID Notes: The White-legged Snake Millipede can grow to around 6cm in length. It is tubular-shaped with a shiny black body and contrasting white legs, of which there are around 100. Immature millipedes are brown, often with pale, longitudinal stripes down the back. It has a pointed telson (legless tail segment) at the end of its body.
Distribution: Common and widespread in the UK. This species can be found year-round in most habitats containing millipedes, including woodland and gardens, or areas with rocks or rotting vegetation to provide cover.

Britain’s rarest plant has been rediscovered in Britain for the first time since 2009. Having been declared extinct after a 22 year absence, a single Ghost Orchid was recently discovered by Richard Bate who has spent the last 30 years searching for it, marking the end of the plant’s lengthy absence. The location of this rare specimen will remain concealed to protect the delicate flower from trampling and poaching, while scientists work to protect the orchid from natural predators and grazing animals.
DNA analysis is helping to eradicate the American Mink from East Anglia. This invasive species has been decimating Britain’s Water Vole and seabird populations since the 1970s, and authorities are now utilising DNA technology to manage their population. Using this key technology, the Waterlife Recovery Trust can estimate relatedness between individuals, identify how far animals may have travelled and pinpoint access routes to remove re-entry points, thus eradicating populations within the project area. The trust has successfully cleared East Anglia of this invasive species, and have seen no signs of mink reproduction in the core project area, resulting in a distinct increase in Water Vole presence.
The world’s fish stocks are in a worse state than previously thought. Research suggests that the scientific recommendations informing fisheries policy are too optimistic and that more global fish stocks have collapsed or are overfished than originally estimated. The study suggests that around a third of ‘maximally sustainably fished’ stocks are actually overfished, which can lead to phantom recoveries where declining stocks are thought to be recovering. The study calls for simpler, more conservative stock assessments and management that are quantified based on realistic models.
Wildlife
An RSPB survey has revealed a hotspot for a threatened species. Data collected from April to June across East Yorkshire and Lincolnshire has found 420 breeding pairs of Redshank on the Humber Estuary, a hotspot for these threatened birds. With a total population of 22,000, this environment holds around 2% of the entire population and is now considered a highly important area for this species of conservation concern.
A network of wildlife charities is calling for the release of beavers across the UK. Following a successful summer of breeding, the trusts have seen an upsurge in kit sightings throughout the UK, sparking a call for further management and strategy surrounding the species. These organisations are calling for the government to produce reintroduction strategies to facilitate their return across the UK and are urging authorities to allow illegally released beavers to remain in their release sites, of which there are over 1,000 in Scotland.
Environment
Countryside river testing reveals pharmaceutical pollution across the UK. Researchers from the University of York tested 54 locations and revealed contamination at 52 sites, with the most common pollutants including antidepressants, antibiotics, antihistamines and diabetes treatments, among others. The study found that rivers in the Peak District were more polluted than samples taken in London, with a total of 29 active pharmaceuticals detected in the region. This discovery marks concerns for antibiotic resistance, human health and concern for the health of freshwater organisms residing in the waterway.
Alongside House Martins and Swallows, Swifts are losing suitable nesting habitat at an alarming rate. Through changes to roof design and structure, nesting sites are becoming increasingly rare. This has contributed to the widespread decline of this species which has seen them added to the UK Red list.
Swifts return to Britain and Ireland from April, following a lengthy flight from Africa. Before leaving in August, Swifts must mate, lay and incubate their eggs. Nest boxes provide Swift colonies with the perfect site to raise their young – boxes should ideally have a large internal cavity with an elongated entrance hole, either at the bottom or downward facing. Swift nest boxes should be placed under the eaves of a building, on walls at least five metres in height. Since these birds nest in colonies, multiple nest boxes or boxes on neighboring houses are ideal for attracting more Swifts.
Here, we look at a selection of nest boxes suitable for Swifts, highlighting the benefits of each design.
Key materials
Wooden nest boxes are preferred by many. This lightweight material is breathable and provides excellent insulation for nesting birds, helping to protect them from temperature extremes between seasons. Typically used for external boxes, harder wood types provide a fair level of robustness and longevity when at least 15mm thick and help to prevent predator access to the nest. The main drawback of wooden nests is the maintenance they require – they should be monitored to ensure the wood remains in good condition, and care taken in choosing wood treatments as many can be harmful to nesting birds.
WoodStone and Woodcrete are almost identical in composition, but Woodcrete is a patented material by Durisol. The material is made from a blend of wood and concrete to produce long-lasting, very durable boxes which can last for decades. It has good insulative properties and creates a thermally stable environment inside the box to shelter inhabitants from extreme temperatures. This material is offered for both built-in and mounted nest boxes but is more often used for built-in boxes due to its weight, which is heavier than wood or eco-plastic. WoodStone is typically more expensive than other materials and requires thoughtful design to improve ventilation to prevent the buildup of moisture in the nest.
Certain components of a bird box may be made with eco-, or regular, plastic. A low-cost option, plastic is more lightweight than Woodcrete, and provides more longevity than wood. This weather resistant material is easy to maintain and is often sourced from recycled plastics. Nest boxes featuring eco-plastic require careful design to mitigate issues with insulation and ventilation. This material is, however, less durable and provides little resistance to predators or extreme temperatures.
This built-in box provides Swifts with a thermally stable, secure nesting space. Woodstone is a durable, long-lasting material that is perfect for new builds.Because it is constructed to standard brick dimensions, this nest box can be rendered over to better blend into constructed walls.
This box provides nesting birds with ample nesting space in a single internal cavity. Woodstone material improves the thermal stability and longevity of the box, while maintaining breathability. This build-in box is also suitable for sparrows, Starlings and other small urban birds.
This built-in box from Unitura is designed to be mounted in eaves and soffits and features a sloped nesting board to allow for mounting at multiple angles. The box has one wood-concrete entrance for extra durability, and a durable plywood box for longevity. This nest box has two nesting bowls to encourage colony nesting.

This robust nest box is constructed entirely of woodstone, ensuring a long-lasting, enduring design and thermal stability throughout the year. A rear entrance provides easy access for cleaning, and a downward facing entrance hole discourages other small garden birds from occupying the nesting space.
This nest box has a single cavity for nesting Swifts and an elongated entrance hole. The wood–concrete material ensures a climactically stable, long-lasting environment for generations of Swifts and a sloped roof ensures adequate drainage.
This robust nest box provides a single compartment for nesting Swifts, with excellent insulation for stability in extreme temperatures. An oval entrance hole and sloping roofs help to exclude Starlings and encourage Swift settlement. Designed to be placed under eaves, the mounting plates and openings are on the sides to allow close-fitting insulation.
Available with left and right-hand side entrances, this box provides nesting Swifts with an underside entrance and landing ramp for easy access. The wood construction is naturally fungal and insect repellent and provides nesting birds with a well-insulated, stable environment.
A hybrid box designed to house both Swifts and bats, the Kiki nesting box provides a thermally-resistant environment suitable for both groups. The compartment that is allocated for Swift nesting has a forward-facing entrance. The durable, long-lasting design can have a lifespan up to 25 years.
Constructed with an upcycled material made from recycled waste insulation, this double-chambered swift box is 100% resistant to moisture and has a long lifespan of up to 25 years. It is lightweight and simple to construct, making it a worthy addition to an existing structure. The excellent thermal properties, and downward-facing entrance, make this an attractive nesting choice for visiting Swifts.
An unobtrusive nest box, the Manthorpe Swift Brick provides nesting birds with a long-lasting, secure nesting site. This nest box is designed to sit inside the insulation cavity of a building, helping to create a thermally stable environment. This brick is available in six colours to blend into existing brickwork.
