Whether you have upcoming new developments or are looking to enhance existing construction projects with wildlife habitat, you may have come across the term ‘woodcrete’, ‘woodstone’, or a variation of the name. This hardy material is commonly used in bird and bat boxes and is often favoured for its longevity and cost-effectiveness. Here we take a closer look at woodcrete, its properties and manufacturing to help you make informed decisions when beginning new construction projects.
What is woodcrete?
Originally patented by Durisol and developed for the construction industry, woodcrete is a building material composed of cement, wood fibres and water. The material is referred to by a number of names, though they are almost identical in composition – woodstone is a trademark registered by Vivara Pro and woodconcrete is the term used by Schwegler, Faunus and Unitura, all suppliers of woodcrete bird and bat habitats.

Woodcrete Properties
A long-lasting, durable material, woodcrete can last for decades. It is weather resistant, does not support fungal growth and unlike wood products, does not rot. It does not leak, warp or crack, making it the ideal long-lasting, secure material for wildlife habitats.
The breathability of the material reduces the risk of issues with condensation, helping to maintain a healthy environment for roosting inhabitants.
It has good insulative properties and creates a stable environment inside the box to shelter inhabitants from extreme temperatures – especially important for maternity boxes where young are resting.
More lightweight than concrete, with great durability and strength, this material is suitable for both built-in and mounted nest boxes. The rough inner surfaces provide texture for bats to cling to, and create a safer, more natural environment for nesting animals. Built-in boxes can also be incorporated into brickwork and can be rendered over to blend into the structure whilst providing habitat benefits for local wildlife.

Woodcrete Applications
Woodcrete is used as a construction material, as well as a variety of building and garden products, including artificial habitat products to support wildlife. These can include bat boxes, bird boxes, insect hides, bee bricks and hedgehog domes. Most commonly, woodcrete bat and bird boxes are available in built-in forms that are installed directly into the walls during the construction of new developments. These boxes are designed to cater to species subjected to habitat loss resulting from the development project itself, or urbanisation in the general area.
The material is made by chipping specially graded recycled waste wood and mineralising the chips to neutralise sugars. The chip is mixed with cement and water to create the woodcrete mixture, before being poured into moulds like regular concrete. These moulds are cured at high temperatures to ensure strength and weather-resistance and can take a considerable amount of time for the full curing process to take place.
The manufacturing of woodcrete products is a lengthy process which can cause longer lead times. We recommended ordering any woodcrete product as far in advance as possible to avoid delays.

Nest boxes can be an excellent way to support biodiversity and incorporate additional habitat into new builds or redevelopments. Some nest boxes are specifically designed to cater to certain species, while others are more generalist and are suitable for multiple species. Generally, bird nest boxes consist of a large internal cavity and an access hole in various shapes or locations depending on the target species. They can be made from a variety of materials, however, woodcrete (or woodstone, woodconcrete) is generally preferred due to its robustness, longevity and advantageous thermal properties.
As low impact, wildlife-friendly construction gains momentum, more choice is added to the market each day, and the range is extensive. We are pleased to offer the largest range of integrated nest boxes in the UK. Here we provide an overview of some of our bestselling models and their benefits.
Integrated Swift Boxes
Swift populations have declined over recent decades due to changes in roof design and the choice of materials used to construct our homes and public buildings. This species typically uses existing holes, cracks and crevices to build their nests, especially those in old buildings, so built-in swift boxes are recommended to provide areas for these birds to roost. These boxes provide large internal cavities within the brickwork that can be accessed by horizontally elongated, often downward facing entrance holes. As colony breeders, it is recommended to site multiple swift boxes together, situated with a clear flight path. The boxes should be installed at a minimum height of 5m on a non-south facing wall and should have no less than 40cm between entrance holes.
Installed flush to the wall or can be rendered over
Long lasting and durable
Integrated Sparrow Boxes
House Sparrow populations have undergone significant declines in previous decades and remain in a vulnerable state in the UK. As colony nesters, this species would benefit from boxes that are installed close together, or a larger, terraced box with multiple connected chambers. These built-in sparrow boxes consist of a durable woodcrete housing with a discrete entrance hole and a large cavity chamber (or alternatively multiple chambers) for nesting.
Can be integrated into the build or fixed to external walls
Removable front panel
Multiple chambers
General Purpose Integrated Bird Nest Boxes
Built-in bird boxes have inclusive designs to cater for a number of bird species, and usually consist of a woodcrete nest box with a cavity space and a discrete entrance hole. These self-contained concrete nests are unobtrusive and are typically installed flush to the wall or can be rendered over for more pleasing aesthetics.
Can be integrated into walls and rendered over, or can be mounted onto external walls
Suitable for multiple species
Custom Integrated Bird Boxes
Bird boxes typically consist of a solid box made from insulating materials with an internal nesting space. They can be custom faced with a chosen brick type (or existing brick, wood, stonework or rendered finish) to allow for discrete installation and a better blend into the existing facade.

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.
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.
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.
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)
Image by Alaska Region U.S Fish and Wildlife Service via Flickr
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.
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.
In ten chapters, each dedicated to a different bird, this book travels the ocean paths along with them, looking at the way their bodies work and the strategies needed to survive in the most demanding environment on earth.
The second-generation Song Meter Mini Bat 2 is one of Wildlife Acoustics’ latest additions to the Song Meter range. This recorder offers improved battery life and weatherproofing, thanks to the new hinged enclosure. Learn more about the improvements and differences in this newer model here. Wildlife Acoustics have now gone one step further offering both AA and Lithium-Ion battery models of the Mini Bat 2. The Lithium-ion model holds 6 rechargeable 18650 lithium-ion batteries giving it 2.5 times more battery life compared to the AA model.
I took the Mini Bat 2 recorder and set it up for a week in June. As I was only recording for a week, the AA model was more than fit for purpose. I had two aims in mind; firstly, I wanted to see for myself how to deploy and use this newer model, and possibly more importantly, I wanted to discover which bats were living just outside the NHBS office.
Deployment
I set up the device using a 64 GB SDXC card and eight lithium AA batteries (other AA batteries are compatible but may offer shorter battery life). I chose to set up the recorder outside of our office on a nearby tree situated alongside the River Dart. I hoped that the presence of insects along the river would encourage bats to fly close to the recorder. However, I did experience some issues with this location which I will discuss later.
Recorder set up with batteries and SD card.
Like its predecessor, the Mini Bat 2 is configured using the free Song Meter app. Here you can select your preferred recording schedule and check the recorder’s status. Whilst in Bluetooth range, you can determine the currentstatus of the recorder, including SD card capacity, battery life, recording mode and number of recordings taken. I used a pre-set recording schedule to record bats from sunset to sunrise (subject to triggering).
Recorder status before deployment.
This model now helpfully features cable lock holes so that the unit can be secured – using a Python Lock I fixed the device to the tree and left it for a week to collect recordings.
What I found
By the end of the week, I had collected over 700 recordings. Despite this, very little battery life had drained and only 3 GB of storage had been used.
Recorder status after deployment.
I then removed the SD card and loaded the recordings into Kaleidoscope Pro. Unfortunately, I noticed a consistent disturbance present in all the recordings at around 20 – 30kHz. It was then I learned that the office has a ventilation fan, which unbeknownst to me, runs constantly (even at 3 am!). Not a bad reminder that when choosing your recording location to be aware of any possible noise disturbances.
Thankfully, this disturbance did not hamper my ability to analyse the recordings. Helpfully, Kaleidoscope Pro has an auto ID feature which allowed me to categorise the recordings by species. This feature compares each call pulse with reference libraries and generates a confidence interval from 0-1 called a “Match Ratio”. The more commonality a pulse shares with the reference data the higher the match ratio. I was delighted to discover that Kaleidoscope identified five different species just outside our office! My personal favourite being the Greater Horseshoe Bat, as we share a love of caves. Unfortunately, these species are now largely confined to south-west England and south Wales in the UK, so I feel very fortunate that I was able to record them.
Examples of the recordings can be viewed as sonograms below.
The Song Meter Mini Bat 2 is an excellent ultrasonic passive recorder. The unit is compact and lightweight, making it easy to store and carry in the field. The set-up was easy thanks to the simple user interface on the Song Meter App, which you can easily navigate to configure and check on your device. The Bluetooth beacon came in useful throughout the week as it allowed me to see the battery life and SD storage without taking the device down.
The Mini Bat 2 has a highly sensitive ultrasonic microphone capable of capturing high-quality recordings up to 250kHz, covering a truly impressive ultrasonic range. The sonograms above show the clear and distinct waveforms created; characteristic of the different species recorded. The excellent recording quality also helps to simplify the sound analysis when using the auto ID function of Kaleidoscope Pro.
The Song Meter Mini Bat 2 is a great addition to the Wildlife Acoustics range and features many improvements over its predecessor. It’s easy set up and deployment, making it simple and engaging to use. With its improved weatherproofing and in-built Bluetooth beacon, the Mini Bat 2 is a brilliant choice for remote recording. Furthermore, the increased battery life means the unit can be used for short- and long-term surveys.
In summary, the Mini Bat 2 is a fantastic all-rounder with a wide array of configurations and capabilities making it an ideal recorder for both enthusiasts and researchers.
The range of integrated or built-in boxes designed for bats can be overwhelming. For new developments, or renovation projects, you may be searching for bat boxes to incorporate additional habitats into your build, and support species while providing new infrastructure. With an upturn in low impact, wildlife friendly construction, integrated bat boxes are becoming increasingly relevant in the construction sector. Bat boxes are designed to provide an appropriately sized, predator-free space for bats to roost or hibernate. They are often designed to be built-in to the building itself, whether this be roofing or brickwork and are unobtrusive, often hard to spot, and help to provide various species with a permanent roost.
There are 18 bat species in the UK, all of which use the same areas of buildings to roost in the absence of natural habitats – most commonly cellars, roofs and loose brickwork, among many more. In general, bat boxes should be placed between 3-6 metres high, in a sunny location with around 6-8 hours of direct sunlight. It is also best to avoid placing these in areas around artificial light. For built-in products, woodcrete (or woodstone, woodconcrete) is preferred due to its durability, longevity and good insulative properties.
Here we discuss integrated bat boxes, providing an overview of our selection of bat boxes and their benefits.
Types of Integrated Bat Boxes
Bat Tiles, Bricks and Panels
Tiles, bricks and panels provide bats with an access point to a suitable roosting space, whether this be within the roof, ridge tiles or a cavity area behind bricks and panels. They are designed to be incorporated into the build itself during construction or renovation and should be provided with suitable roosting cavities behind the access point, usually in the form of bat boxes or insulation-free cavity space.
Provides bats with an entrance to underfelt or open loft
Protection from heat extremes
Available in five traditional tile colours
Integrated Bat Boxes
Bat boxes are designed to cater for either crevice and cavity dwelling species through varying complexity or can occasionally be a hybrid design to encourage uptake from both groups. These self-contained roosts are unobtrusive and are typically installed flush to the wall or can be rendered over. Bat boxes can also be designed for hibernation and breeding, providing a well-insulated, larger space to accommodate breeding colonies and larger groups.
Bat boxes typically consist of a solid box made from insulating materials with an internal roosting space. They can be custom faced with a chosen brick type (or existing brick, wood, stonework or rendered finish) to allow for discrete installation and a better blend into the existing facade.
Available in a variety of facings to suit any existing brick, wood, stonework or aa rendered finish
Insulative properties
External Bat Boxes
An alternative to integrated habitat boxes, externally mounted bat boxes can be attached to trees, fences, or buildings and are typically made of woodstone or woodcrete. These versatile boxes can be designed for summer roosting, hibernation, or maternity roosting, varying in size to accommodate different species.

Though bears loom large in our collective imagination, their flesh-and-blood counterparts are increasingly losing ground. Eight Bears, the debut of environmental journalist Gloria Dickie, draws on visits to key hotspots where Earth’s remaining bear species come into conflict with humans. By interviewing scores of people, both conservationists and those suffering at the paws of these large predators, this nuanced and thought-provoking reportage asks whether humans and bears can coexist.
The roots of this book go back to 2013 when Dickie started a master’s in environmental journalism and midway settled on bear-human conflicts in the Rocky Mountains. Since then, she has travelled to Asia and the Americas to see first-hand all eight extant bear species. The only obvious regions missing from her story are Alaska, Russia, and Europe, all of which have large populations of bears. Even so, she has visited a formidable list of destinations. As an aside here, kudos to both the stylish bear portraits by Arjun Parikh opening each chapter, and Dickie’s meticulous list of notes. The latter mentions the many people she has interviewed or corresponded with over the years and, for some sources, provides additional notes that are too detailed for the main narrative.
The first half of the book’s subtitle promises a look at the bear’s mythic past. Though there is mention here of the predominance of bears in northern hemisphere cultures, the so-called circumpolar bear cult tradition, and the rarely discussed role of the bear in Peruvian culture and history, this is a minor motif in the book. Much more can be and has been said about the cultural history of bears.
Instead, as seems unavoidable when writing about megafauna nowadays, the focus of Eight Bears is on the second half of the subtitle, their imperilled future. The outlook is grim and Dickie early on mentions that “almost everywhere I went, bears seemed to be a shadow of what they once were” (p. 8). Probably the biggest threat is habitat loss, followed closely by hunting and poaching. A historic combination of these two decimated North American bear populations under European settlement. Polar bears have become the poster children of climate change, though the disappearance of sea ice is yet another form of habitat loss. I would be remiss if I did not mention that several whistleblowers have argued that hunting poses a continued but underappreciated threat to polar bears. Asia is additionally home to some particularly grisly practices: sloth bears are beaten into submission to become dancing bears, and moon and sun bears are experiencing years of, what is effectively, surgical torture on bile farms. The former has been outlawed with a reasonable degree of success, the latter less so. From her descriptions, Dickie visits the same bile farmer and speaks to some of the same people that Nuwer interviewed for her 2018 book Poached. Little seems to have improved in the intervening years, unfortunately.
Though bears are usually at the losing end of human-wildlife conflict, Dickie does not avoid exploring the flipside. Many readers outside of Asia might be surprised to learn that the inappropriately named sloth bear is easily the world’s most dangerous bear. In India, more than 100 attacks every year kill or gruesomely injure predominantly poor, rural people, with Dickie seeking out some of the victims. In the USA, where grizzly populations are recovering, she speaks to ranchers and farmers who lose livestock to bears and frequently object that “liberal urbanites are the ones who want predators back on the landscape, but they aren’t the ones suffering the consequences” (p. 177). In Canada, she visits the remarkable tourist town of Churchill at the edge of Hudson Bay which is home to equal numbers of humans and polar bears. To keep people safe while avoiding lethal control methods as much as possible, it relies on an unprecedented amount of technology. Even so, human lives are at risk, and Dickie speaks to a woman who survived a mauling.
The chapters focusing on bears in the USA offer some of the most remarkable case studies of people attempting to live alongside bears. The century-long history of black bear management around Yosemite National Park offers “a full-scale experiment of all the ways people and bears can clash” (p. 153). After decades of park management doing things wrong (making a tourist attraction out of bears scavenging on garbage dumps, thus inadvertently training a generation of them how not to forage in the wild), they spent decades trying to do things right. A combination of bear-resistant food storage containers on campgrounds and strict enforcement of rules has trained tourists to be more mindful.
Eight Bears becomes more thought-provoking as it progresses. Here is how it provoked mine. Dickie puts down several relevant dots on paper at different points in the book (mentioning human population growth, climate change, and the resource-hungry global supply chain) but she does not explicitly connect them to draw the contours of the larger challenge ahead. So, here be a tangent, and my attempt to connect those dots, triggered by her repeated interviewing of grizzly bear recovery coordinator Chris Servheen. Upon retirement in 2015, with grizzlies sufficiently recovered, he supported their delisting. However, by 2021, seeing how states were failing to manage grizzly populations “with maturity and grace” (p. 180), he changed his mind. This raises fundamental questions. What is the point of all our conservation efforts if we do not address the root causes that got threatened species in trouble in the first place? For me, books such as Abundant Earth and Alfie & Me have really driven home the point that, unless we change our relationship with the natural world and stop treating it as a bottomless larder, conservation is little more than a palliative solution, a stay of execution. If we restore animals to an increasingly degraded environment, to a human population that does not want to share the world with them, they will have to remain on permanent life support. To be clear, I do not think conservation is futile; it is vital. So long as it is not an end unto itself. We cannot lose sight of the bigger picture: a world hospitable to non-human animals. Servheen’s call for “maturity and grace” in the context of grizzly bear management can just as well be applied to our tenancy of this planet.

Even if you were to come away from this book without having your thoughts similarly provoked, Eight Bears is a mighty fine environmental reportage that is nuanced and well-researched. Given the often regional nature of books on bears and people, Dickie’s globetrotting overview of the challenges faced by all extant bears is very welcome.
‘Effectively protected’ land in England has declined to just 2.93%. With the government’s commitment to protecting 30% of Britain’s land and sea by 2030 fast approaching, campaigners warn that swift, direct action is needed to overturn these declines. Ocean protection has increased to 9.92% from last year’s 8%, however land protection has fallen to under 3%, less than last year’s estimate. Declines in land protection result from the diminishing condition of Sites of Special Scientific Interest (SSSI) due to climate change, pollution and overgrazing and conservation authorities agree that the UK government will need to take big steps over the next few years to meet 30×30 targets.
The UK Government has pledged £22b to support the development of two carbon capture and storage projects. Based in Merseyside and Teesside, these carbon capture projects will store carbon emissions from industry and energy production to help the UK meet its climate goals. This new industry is regarded as a key element in meeting targets around greenhouse gas emissions and is hoped to attract significant private investment as well as provide 4,000 jobs for local people. The captured carbon will be stored in deep geological storage in the North Sea and Liverpool Bay, with the hopes of removing up to 8.5 million tonnes of carbon emissions each year.
Botanists from Kew’s Royal Botanic Gardens believe there are around 100,000 plant species yet to be discovered across the globe. A study revealed 33 areas that are likely to contain great numbers of undiscovered species and highlights regions in which botanists should be concentrating their search for new plants. By increasing the rate of discoveries, scientists hope to better target conservation and preservation, and discover these species before they are lost to extinction. Of the 33 areas identified, most are in Asia and include Vietnam and the eastern Himalayas. Africa, South America, Madagascar, Colombia and Peru have also been identified as key areas of interest.
Satellite data analysis from the University of Exeter has reported greening across the Antarctic continent. Due to the acceleration of the climate crisis, plant cover in the region has increased more than tenfold over recent decades, expanding from just 1km2 in 1986 to nearly 12km2 in 2021. Comprised mainly of mosses and green algae, this greening leaves the continent open to invasive species colonisation from foreign visitors. Although still dominated by ice, the growth of vegetation in the region is cause for concern and could facilitate further soil formation due to an increased presence of vegetative organic matter.
Conservation
Pine Martens have been successfully reintroduced to south-west England. In September, fifteen Pine Martens – eight females and seven males – were released in undisclosed locations on Dartmoor National Park for the first time in 150 years. After being driven to extinction by habitat loss and persecution, this translocation will reinstate natural predator-prey interactions and processes. Next year, the project will turn its attention to Exmoor National Park to translocate another group of these elusive mustelids.
Salmon numbers in England and Wales took a sharp decline in 2023. In a report by CEFAS and the Environment Agency, data showed that last year’s salmon stocks were at the lowest since records began in 1997 – declared catch in 2023 totalled 5,399, nearly 1,500 less than the year before. There are 64 principal salmon rivers in the UK (rivers which contain significant numbers), and only one of these is classified as not at risk. It is believed that climate change and polluted waterways are directly endangering these fish, as salmon are an indicator species for polluted waters.
The Welsh Government has announced its support for the reintroduction of Eurasian Beavers in Wales. With flood warnings becoming more regular across the country, the reintroduction of these animals could provide Wales with a nature-based solution to tackle water pollution and flooding through the creation of wetland habitats. The project is supported by over 90% of the Welsh population, revealed by a survey that was conducted by the Welsh Beaver Project who have been investigating the feasibility of reintroduction since 2005.
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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
Brought to you by the Sunday Times bestselling author Guy Shrubsole, The Lie of the Land discusses how a handful of wide-scale landowners are responsible for the destruction and degradation of our vital landscapes, painting a humbling picture of some of the most notable failures of land stewardship in Britain’s recent history. However, Guy also presents a glimmer of hope as he relays the stories of those trying to help nature recover, from small-scale farmers to community groups and individuals. In doing so he gives the public hope that we can all become custodians of the countryside once more.

Guy Shrubsole is a researcher, writer and environmental campaigner who previously worked as an investigator for Friends of the Earth, and is co-founder of the Right to Roam movement. He was Policy and Campaigns Coordinator at Rewilding Britain for a number of years and has published a number of books including Who Owns England? and The Lost Rainforests of Britain.
We recently had the opportunity to interview Guy about The Lie of the Land, where we discussed what inspired him to write this book, how the privatisation of land has affected its conservation and preservation, what he hopes the reader can learn from his work and more.
Firstly, can you tell us a little bit about what inspired you to write The Lie of the Land?
I’ve been thinking – and campaigning – about the issues in The Lie of the Land for some years. Witnessing moorland being deliberately set ablaze for the purposes of driven grouse shooting was an early spark; as was reading about the landowners who drained the Fens, and the vast wet commons that once dominated Cambridgeshire which teemed with fish, wildfowl and eels. In some ways The Lie of the Land is a natural sequel to my first book, Who Owns England? – taking its analysis that half of England belongs to just 1% of the population and looking at the ecological consequences of this.
Have there been any instances where private land ownership has benefitted the environment and increased its accessibility for the public, and if so, what can be taken from this?
Absolutely, I discuss in the book how there are some brilliant nature-friendly farmers and landowners doing great work – heroes like Isabella Tree and Charlie Burrell with their rewilding work at Knepp, or Jake Fiennes at Holkham, or James Rebanks in the Lake District. But I argue that we can’t simply rely on these few ‘good stewards’ to turn the nature crisis around on their own. We need to call out bad practice (as Fiennes does in his book Land Healer) and make all landowners more accountable to the public for how they’re treating the land. Look at how England’s peat bogs – a vast natural store of carbon and a crucial national asset in the fight against the climate crisis – have been mistreated by the 150 or so estates that own them and set fire to them each October. Look at the institutional investors who own great swathes of the Fens – organisations like the Church Commissioners – and how they continue to profit from what is essentially a ‘carbon bomb’, the wasted peat soils of the fenland losing fertility and carbon with each passing year.
The trouble is, a lot of estates and lobby groups for landowners hide behind the assertion that they are the ‘custodians of the countryside’, who can be trusted to look after it without the need for public oversight or pesky environmental regulations. But as James Rebanks says, “I’m a very proud defender of good farming, but the ‘custodians of the countryside’ argument only washes if we are genuinely doing that – otherwise it’s self-serving nonsense.”

What do you think needs to be implemented to increase the perceived viability of community land ownership and management, compared to privately owned spaces? And how do you think we can increase the quantity of community land ownership going forward?
We need to give communities the power to take ownership of more land, for starters. That means introducing a Community Right to Buy in England, like the one they’ve had in Scotland for the past twenty years – a set of powers that has led to communities buying up half a million acres of Scotland. I visit one such community buyout in the book, Langholm Moor – a former grouse moor that was bought by the people of Langholm a couple of years ago: they’re now turning it into a nature reserve. No more moorland burning, no more predator persecution: they’re going to re-wet the peat bogs and are allowing birch and rowan to naturally regenerate up the hillsides.
We need to have that opportunity in England, too. And the good news is, the new Labour government announced in its first King’s Speech that it will introduce a Community Right to Buy in England. But we’ll have to campaign hard to make sure it happens, and that landed interests don’t water it down. And we need to unlock our own imaginations, to start to dream bigger about how communities could take control of land and manage it for nature. As the Scottish land reform campaigner Alastair McIntosh has written, community ownership of land “creates a new constellation of possibility.” Let’s reach for the stars.
I particularly enjoyed your last book, The Lost Rainforests of Britain, and it really opened my eyes to the remarkable habitats around us that many people, like myself, never knew existed. Do you think landowners are aware of the importance, in some cases rarity, of the land they own? And how has the privatisation of the UK’s rainforests affected their conservation and preservation?
Thanks! I think an increasing number of landowners and farmers are now aware of temperate rainforests – after writing Lost Rainforests, one of the loveliest messages I got was from a Devon sheep farmer who had discovered the very rare Hazel Gloves fungus growing in an old hazel grove on her farm. And it’s been really encouraging to see such snowballing momentum to bring back Britain’s rainforests since the book was published – like the Wildlife Trusts announcing rainforest restoration projects from Skiddaw in Cumbria to West Muchlarnick in Cornwall, and the Cornish landowner Merlin Hanbury-Tenison doing great work on his farm at Cabilla.
Unfortunately, not all landowners recognise the importance of the habitats they own – even sometimes when they’ve been officially ‘notified’ of their existence through the land being designated as a Site of Special Scientific Interest (SSSI). In the book I tell the story of the landowner who destroyed part of the River Lugg SSSI – and how his example is sadly only one of many instances since the first SSSIs were designated in the 1950s. Ultimately, if we’re to protect our remaining habitats, I think we cannot only rely on voluntary initiatives by enlightened owners, but have to give precious habitats strong legal protections – and make sure our environmental watchdogs, like Natural England, have real teeth.
What do you hope the reader can learn from your book?
I hope that readers get angry about the problems, take inspiration from the suggested solutions, and get out there and campaign for them to become reality!
The final chapter of your book details your 10-step proposal. At which point during the writing process did you develop these, and how did these recommendations adapt and evolve throughout the researching and writing process of The Lie of the Land?
In all of my books, I aim to set out clear political recommendations – for me the point of writing is not just to interpret the world, but to change it! From the outset I had quite a clear sense that all my recommendations in The Lie of the Land would be about how we can democratise decision-making over land, make landowners more accountable and give all of us a greater say over how land is used. That, to me, seems to be our last, best hope of turning the nature crisis around.
My own feelings of optimism about fixing this mess we’re in were definitely boosted by the conversations I had, and site visits I made in the process of researching the book. There are loads of communities yearning to look after land, loads of river guardian groups blowing the whistle on river pollution, and plenty of examples from other countries – and from our own nation’s history – of how we can protect and restore nature and do a better job than we are currently. But we need some policy changes at a national level to unlock these energies and scale them up. As William Gibson (allegedly) once said, ‘the future is already here – it’s just not very evenly distributed.’
Are you working on any other books or projects that we can hear about?
Steady on – I’ve just written this one! Currently I’m enjoying meeting with lots of people across the country to get the ideas out there – and I am campaigning hard for these policy changes. I also work with the Right to Roam campaign (you can join our mailing list at www.righttoroam.org.uk). But I definitely would like to write more books in the future!
The Lie of the Land is available from our bookstore.
Whether you are planning a construction project, are in the middle of a new–build or are looking to update an existing structure, you may be exploring options for providing bat habitats. We have an extensive range of bat boxes available on our website, in a variety of formats and materials. Here we explore thedifferent types, how they may be used and where they can be installed.
Bat Box Material Properties
Bat boxes are constructed with a variety of materials, each with differing properties.
Most commonly used for external boxes, wood is lightweight with good thermal properties for inhabitants. However, it does rot without treatment and therefore does not last as long as other materials.
Woodcrete (also named woodstone or woodconcrete) is a very durable material with exceptional thermal properties and is often the material of choice for built-in boxes. It can also be used externally and can last several decades once installed.
Eco-plastics are used to create lightweight boxes, typically designed for external use. They have good weather resistance and longevity, although less durability.
Concrete is exceptionally durable and is used for built-in boxes. It has good thermal properties but due to its weight, is unsuitable for external mounting.
Maternity Boxes
Typically larger in size with multiple internal chambers, maternity boxes are designed to support breeding colonies by providing a well-insulated roosting space for raising young.
These boxes are mostly made for external installation but are also available in a built-in format which is installed into the brickwork and can be rendered over.
Since these boxes are mostly available in an external form, they can be installed once construction has taken place. Built-in boxes should be fixed during the construction process and installed directly into the brickwork.
An FSC certified crevice box, suitable for roosts or maternity groups.
Bat Tubes
Bat tubes are longer internal cavities with multiple sections or crevices. These are often made of woodcrete and are available in modular versions which can be connected in the facade allowing for side-by-side or a longer tower format.
These boxes come built-in and are incorporated into the building’s brickwork during exterior wall construction where they can be rendered over.
A modular option available in multiple depths and styles for crevice and cavity species.
Bat Bricks
Constructed to industry standard size, bat bricks have a dome-shaped access hole to allow bats into a suitable cavity.
These products are designed to be incorporated into the brickwork of a building, whether this be a new build or an existing structure under renovation, and are available in standard colours enabling them to seamlessly blend into existing walls. When installing bat bricks, it is important to ensure that a chamber free from insulating material is available behind the access brick to allow bats to safely roost.
A standard-sized brick available in red, golden and brown colours.
Access Tiles and Panels
Similar to bat bricks, these tiles provide an access point to open roof space or the underfelt of the roof, allowing bats to roost in confined spaces beneath the tiles. They can be installed within the roof or ridge tiles during construction, or they may be used to replace tiles on existing structures, and are available in multiple colours to blend seamlessly into existing tiles.
Bat access panels are also available to provide bats access to a roosting site, and are particularly advantageous for renovation projects with existing roosting colonies. These panels can also be rendered over, and can be installed at any point during construction.
Access tiles and panels require an insulation-free cavity behind the product to provide roosting space.
A woodconcrete access panel with an overall depth of just 8cm for easy integration.
Bat Box
These boxes are available as external or built-in designs and consist of a simple box with an entrance hole and varying interiors. Bat boxes can come in a range of forms, and can have one large, single cavity or a multi-chamber interior and can cater to both crevice and cavity-dwelling bats. There are also hybrid options, where a box is designed with cavities for multiple species, for example a box may cater to bats and Swifts.
Built-in boxes are designed to be installed among the brickwork and can be rendered over. External boxes can be mounted to trees, fences and buildings with the appropriate fixings. It is important to consider the weight of an external box before mounting, more lightweight boxes (made from wood or plastic for example) can be fixed to trees, but heavier woodcrete boxes should be fixed to a solid structure.
Features a single internal cavity that is suitable as a summer roost.
Rocket box
Rocket boxes are large, pole-mounted habitats that provide a large roosting area over multiple chambers. Typically made with a plastic shell, these boxes allow for 360 movement and are available with both crevice and cavity designs.
Rocket boxes are external and do not attach to any part of the building. They are particularly useful when there are no suitable trees for external boxes, and a wall mounted box is undesirable. They have also been used to provide an alternative roosting site near building works.
