Author interview with Richard Broughton: The Marsh Tit and the Willow Tit

Marking the first monograph for either species, Richard Broughton’s The Marsh Tit and the Willow Tit reveals the remarkable lives of these wonderful little birds. Compiling decades of personal research, as well as a detailed review of external studies from across both Europe and Asia, it explores each species’ taxonomy, food and foraging patterns, social organisation, challenges and conservation, alongside more than 150 illustrations, maps, charts and photographs.

Dr Richard Broughton is a research ecologist with a wealth of experience across birds, mammals, forests and farmland in Great Britain and Europe. He has studied Marsh Tits, Willow Tits and their habitats for over 25 years, and prior to this he completed a Master’s degree in GIS as well as a PhD in Marsh Tit ecology, before joining the UK Centre for Ecology & Hydrology in Cambridgeshire.

We recently chatted to Richard about his inspiration for the book, which challenges he faced when developing such a detailed study of these two species and more.

You have studied Willow Tits and Marsh Tits for much of your career. What initially captivated you about these charismatic birds, and what inspired you to write a book about them?

I had Willow Tits on my local patch in Hull when I was a youngster at school, and I had Marsh Tits and Willow Tits around my first office near Huntingdon when I started my science career. Both species were always a bit special and enigmatic – not so common that you saw them every day, but when you did it was like seeing parallel lives going on around you. They’re a lot like us, mostly preferring to live as couples in stable relationships, with busy social lives and a close attachment to their neighbourhood.

From a research perspective, Marsh Tits and Willow Tits are fantastic species to study. They are widespread from Britain to Japan, they’re territorial and they don’t migrate, so the same birds are present all year round and you can really get to know them – how they communicate, organise themselves within their communities and solve the problems of living in different types of woodland, it’s all really fascinating. And there’s so much that we still don’t know, with lots of discoveries to be made, but also some urgency. We don’t fully understand exactly why they’re declining in many areas, so the inspiration for writing the book was partly to bring together all that we know about their ecology and what pressures they’re facing. If Marsh Tits and Willow Tits are struggling, then we need to listen to what this is telling us about our woodlands and forests.

Both species have suffered severe range declines – how can the general public work to better support these birds amid habitat loss and climate change?

The main thing is to know where Marsh Tits and Willow Tits are still hanging on, and where they are declining – taking part in surveys and reporting sightings to the county recorders and BirdTrack are great ways of helping to monitor both species. Protecting and expanding their habitat is essential, but for that we need to know where they are, and in what numbers.

It’s also important to realise how we can unintentionally make things harder for Marsh Tits and Willow Tits when we do favours for their competitors. There is growing evidence that increasing numbers of Blue Tits and Great Tits could be harming Marsh Tits and Willow Tits by taking over their nests and dominating their foraging space. The vast scale of bird-feeding in gardens, woodlands and nature reserves is changing our woodland bird communities, and it really boosts the dominant species, which can then put extra pressure on Marsh Tits and Willow Tits. For this reason, it’s important to consider the unintended negative impacts of well-meaning interventions, such as bird-feeding and nestboxes, on more vulnerable species like these.

I was surprised to learn about the ineffectiveness of nest boxes in supporting Marsh and Willow Tit populations in relation to competition. Do you think this is also the case for other species across the UK, and what alternatives could we use to mitigate this issue?

The problem with nestboxes for Marsh Tits and Willow Tits is that they’re far more likely to increase the densities of their dominant competitors, especially Blue Tits. If you add more nestboxes to a woodland then you will get more Blue Tits, but Marsh Tits and Willow Tits don’t work that way.

This is because they have much larger territories, and you could fit 15 pairs of Blue Tits into a typical Marsh Tit or Willow Tit territory. These large areas contain enough natural nest sites for Marsh Tits and Willow Tits, and so these species are limited by the area of woodland habitat and not by tree cavities or deadwood for building their nests. As such, adding nestboxes cannot increase the numbers of Marsh Tits or Willow Tits like it does for Blue Tits.

This shows how it is important to fully understand a species’ ecology for any conservation actions to work. A better solution is to promote diverse, wilder woodlands that have plenty of opportunities for Marsh Tits, Willow Tits and other woodland species at more natural densities. If not over-managed, woodland can quite quickly develop enough nesting sites on its own.

Within the book you mention the woodland restoration projects being undertaken in Scotland, which are striving to establish woodlands to support native species, including Marsh Tits and Willow Tits. Can re-establishing these complex habitats truly help to encourage population growth? And what would be your main recommendations for large-scale restoration projects with these species in mind?

Expanding woodland habitat is a good way to help buffer Marsh Tits and Willow Tits from population declines, as the losses in Britain are greatest in areas of more fragmented habitat. In Finland, too, logging and habitat loss is driving population declines. Increasing the amount of woodland reduces habitat fragmentation, which in turn helps birds to disperse across the landscape and provides space for more breeding pairs, so it can only help. The natural range of Willow Tits, and probably of Marsh Tits, once covered much of Scotland, and so restoring forest cover in that country could help to re-establish their populations.

Looking ahead, Scotland could eventually provide an important refuge for Marsh Tits and Willow Tits, being further from the intensive agriculture, urbanisation and more intense warming of southern Britain. We can look to other natural and regenerating forests in Europe to see what this restoration could look like in Scotland and elsewhere in Britain – varied tree density and structural diversity, lots of standing and fallen deadwood, and plenty of water in streams, pools and soils. Where we still have such places in Europe, like in Poland’s Bia?owie?a Forest, then Marsh Tits and Willow Tits both find places to live in different parts of the same woodland.

The Marsh Tit and the Willow Tit is very thoroughly researched and includes an extensive breadth of information. Did you encounter any challenges when developing such a detailed study of these two species?

I was lucky that there have been major studies of Marsh Tits and Willow Tits in Europe over the past century, and I have been involved with several of them in recent decades, so I was familiar with their findings. For other studies, it has never been easier to find and access published papers and reports online, and even to translate them automatically.

Nevertheless, it was still quite challenging to find many studies from Asia, which is where more than half of the world’s Marsh Tits and Willow Tits are thought to live, along with their closest relatives, the Black-bibbed Tit, Caspian Tit and Sichuan Tit. This is slowly changing, as more research is being done in China, Japan and South Korea, but there are still large gaps. In Europe, too, we still know relatively little about Marsh Tits or Willow Tits in some regions. Even in Britain, the recent discovery of a previously unknown population of Marsh Tits in the Scottish Borders shows that we still have things to learn!

What have been some of your favourite moments while researching this book? And did any of your discoveries surprise you?

It’s been a great pleasure to look back through all of the previous studies of Marsh Tits and Willow Tits and pay tribute to the dedicated researchers who spent so many years in the woods and forests, peering into the lives of these little birds. What shone through for me is just how connected the forest ecosystem really is. Marsh Tits and Willow Tits are part of a complex web of life, with some really surprising relationships. For example, Bison and Red Deer stripping bark from trees helps to create the cavities that are the Marsh Tit’s favourite nest sites. Meanwhile, Willow Tits forage on carrion from Wolf kills, which helps them to survive northern winters. At the other end of the spectrum, Marsh Tits and Willow Tits both drink nectar from blossom and might be significant pollinators of woodland shrubs, and they might also be seed dispersers for some woodland plants.

We’re just starting to understand these relationships, but in many parts of Europe they have been broken by the loss of forest species, such as large mammals. It’s exciting to think that nature restoration and rewilding could rebuild some of these ecological networks in our woodlands. Again, there’s still so much to learn about Marsh Tits and Willow Tits, but getting to know them opens a window into the wider forest ecosystem, and the more you look, the more you find.

Finally, what is occupying your time now? Are there new books on the horizon that you can tell us about?

I’m still monitoring my Marsh Tit population at Monks Wood in Cambridgeshire, coming up to 24 years of study, and I’m busy with interesting research at UKCEH on hedgerows, woodland regeneration, sustainable farming and nature restoration. In the past year I’ve been busy as the new Editor in Chief of the BTO’s scientific journal Bird Study, helping other researchers to publish their studies. I’m also still involved with research at the Biaowiea Forest in Poland, which always has exciting opportunities, and last spring I was there finding the nests of Marsh Tits, Willow Tits and Wood Warblers. The Wood Warbler is another declining woodland bird that has lots of really fascinating and surprising behaviour, and that’s another species that I think could be worth writing about.

The Marsh Tit and the Willow Tit is available to order from our online bookstore here.

This Week in Biodiversity News – 18th November

Extinction

A paper published over the weekend revealed that the Slender-billed Curlew is likely to be extinct, with the last sighting recorded in Morocco in 1995. Marking the first known global bird extinction from the Western Palearctic, this species was previously common across mainland Europe, north Africa and west Asia, with populations found nowhere else in the world. The confirmation of the loss of this species of curlew comes just a month after COP16 took place in Cali, Columbia, which focused on increasing efforts to halt the loss of flora and fauna.

Wildlife and environment

Deforestation in the Amazon has fallen by 31%, marking a nine-year low. Despite this, deforestation is still a concern for Brazil, and an area the size of Delaware was cleared within the last year. The Amazon is facing a different set of pressures as climate change progresses – severe drought has contributed to a significant 18-fold surge in wildfires, which is impacting much of South America, including the biologically rich Pantanal in Brazil.

One of Britain’s rare mammals has been found in the Pembrokeshire Coast National Park. As an element of the park’s Cysylltu Natur project, which aims to protect 25% of the park’s northern section by 2025, dormouse nesting tubes were placed along areas of woodland on site. Licensed volunteers have discovered that dormice have inhabited the boxes, resulting in an exciting milestone in boosting nature recovery for the park.

Conservation

Two sites on the rivers Wear and Tyne are under consideration for saltmarsh restoration. Groundwork North East & Cumbria have applied for permission to undertake work in these areas to compensate for construction along the riverbank and heavy industrialisation in the area. The work will expand and restore existing habitat without removing waterside infrastructure – this restoration will slow the river flow and allowing sediment to build, in turn providing habitat for fish, invertebrates and other aquatic life.

The first of fourty-eight Local Nature Recovery Strategies (LNRS) has been developed for the West of England. The strategies are conceived by local authorities, communities, NGO’s and government agencies to identify focus areas for nature. These locally led, evidence-based plans were conceived to prioritise nature investment and target efforts for environmental restoration where it is needed most. LNRS’s will eventually be rolled out to cover all of England, helping to coordinate target action to meet biodiversity commitments.

Cairngorms National Park has launched an initiative to save one of Scotland’s most threatened tree species – Aspen. Partnered with Trees for Life, the Cairngorms National Park Authority will be mapping the health and location of existing Aspen populations, and the data will be used to guide the planting of new trees within the forest. Deemed one of Scotland’s most vital native trees, this once-common species has undergone extreme declines due to deforestation and overgrazing. It is hoped that the project can be used as a blueprint to roll out Aspen conservation across Scotland, securing biodiversity benefits for the environment.

Policy

Prime Minister Keir Starmer has revealed new climate targets for the UK. Announced at COP29 in Azerbaijan, the UK will now aim for 81% reductions in emissions by 2035. This new target updates a previous pledge of 78% made by the Conservative government, and comes after recommendations from the UK’s Climate Change Committee. This new pledge will help to support the UK’s move to net zero by 2050, and although the UK is currently running behind on delivering cuts, this new target will provide local economic growth and investment.

The Environmental Audit Committee will be examining the environmental impact of Labour’s planning reforms. This inquiry comes after an early pledge to build 1.5 million homes over a five year period. To do this, there are proposed changes to the national planning policy framework, which would enable the government to release land for housing development. The inquiry will question whether these reforms can maintain current levels of environmental protection, and is seeking views on the implications of these reforms on nature and the climate.

Author interview with Dr. Tim Reed: Protected Species and Biodiversity – A Guide for Planners and Ecologists

Protected Species and Biodiversity: A Guide for Planners and Ecologists is a comprehensive, accessible book that collates every key element required to gather and interpret survey data for protected species.

Progressing through individual species and group tables, and providing information on planning systems, biodiversity, government guidance and its interpretation, how to secure better quality data, biodiversity net gain and more, this guide also codifies what a planner can expect from an ecologist to ensure the effective safeguarding of protected species. As such, it is an essential reference guide for planners and ecological consultants alike.

Dr. Tim Reed has had a lifelong interest in the use of data quality and survey methods as a basis for credible decision-making by those whose actions influence landscapes and protected areas. This has included developing survey methods for waders on moorland, standardising nature reserve management plan formats, chairing development groups for national-level databases, and collaborating with the EU on data standards for directives. Over the past 20 years, Tim has helped major worldwide corporate companies establish biodiversity as part of their risk-management processes, while also working on public inquiries across the UK.

We recently had the opportunity to chat to Tim about what inspired him to write a book aimed at planners and ecologists, how Biodiversity Net Gain (BNG) could potentially affect protected species across the UK, the importance of technological advancements in accurate data collection and more.

Firstly, as someone who has spent most of their career working in planning and sustainable development, what inspired you to write this book?

Years ago, when working on immigration and extinctions in island bird communities, one of the things that impressed, but also worried me, was the extreme variability in the quality of data from year to year. Were the gaps in species records (apparent extinctions) real, or were they due to issues with data collection or recording? Moving onto protected areas and the related planning policy framework, the same problems with data quality surfaced there.

Later, when I began working on planning disputes it was clear that local planning authorities (LPAs) were staffed by good, but often overwhelmed, planners. A series of Association of Local Government Ecologists (ALGE) reports have confirmed this. ALGE reckoned there were issues of capacity (people/time) and competence (often limited specialist knowledge) that stopped LPAs doing what they wanted to do. These remain today.

Looking at the often frankly poor material dumped onto them by would-be developers, it was and is hard for planners to know how to address it, how to find out what’s needed, and where the gaps were and are. Suitable methods had been scattered across journals, books, and specialist documents, and were often hard to fathom. The absence of a recent one-stop synthesis of most of the material needed was the main driver for Protected Species and Biodiversity; trying to fill an acknowledged hole. The fact that Natural England and DEFRA’s guidance for Protected Species left much to be desired was a further problem. The idea of the guide was to try and provide an accessible way of seeing what needed doing. Something that would be suitable for planners, householders and developers’ ecologists alike – and for LPA planners to use and see if what had been claimed by applicants had been done properly, or not.

If the guide works, then the hope is that a better, more informed level of debate can take place. If so, better data will be provided and protected species and biodiversity will be the winners. The core methods section (Chapter 5) is suitable for protected species in England, Wales, Scotland and Northern Ireland.

Biodiversity Net Gain is a recent development in planning and land management. How do you think the introduction of this policy will affect protected species across the UK?

As I try to show in the last bit of the guide, BNG isn’t focused at all on protected species; delivery is still expected through protected species legislation. Yet, there is clearly a hope that BNG will sneak in more of all sorts of species, some of which may be rare or protected. Duffus et al (2024) have neatly shown that the score in the area-condition metric used by BNG isn’t related to either species richness or abundance. Instead, more information is needed, along with species surveys. If so, then they need doing well – and there is a debate to be had on that in the guide too.

This book emphasises the importance of collecting high-quality data for use in planning. As data quality improves, could there be a shift in our understanding of the UK’s condition? And could the true state of the UK’s biodiversity be worse than we initially thought?

Better knowledge, better use of standardised methods, and a better understanding of what the resultant data does or doesn’t mean, along with less use of unverified mitigation techniques: all will help us understand potential impacts of planning proposals on biodiversity a little bit better than we do now.

Better data might well show problems, but could also help in some circumstances by showing that some things are better than we thought, or by waving a flag before it is too late to act. Getting consistently reliable data will allow more meaningful actions at a local and wider scale.

Chapter 5 offers an extensive insight into the data local authorities should collate when conducting an in-depth evaluation of protected species. Did you face any challenges in keeping this section accurate?

Of course things do, and will continue to, change. Even when the first draft of the text was completed there were basic changes in NE/DEFRA guidance that required reappraisals and revisions. The species guidance was equally dynamic. So, yes, it was tricky keeping up to date. The role of the guide is to bring together what we knew at the time of writing in an accessible way. If things change dramatically, there may be a case for a revised version in 5-10 years’ time. But in the meantime, it is there and might as well help people trying to understand what needs doing, or where claims need contesting, and why.

How important do you think technological advancements, such as bioacoustic methods, will play in collecting more accurate data?

Technology is critical in helping us better interpret the environment. For example, I use a range of bat recorders, and recorders have got better, and more efficient with time.

Technological improvements are fine, but they still come with error terms. Knowing and stating the limitations of methods and data are critical to help us understand what we can and can’t do with a set of data. In Public Inquiries, I regularly saw untenable claims relating to bat data that rarely matched the reality of the technology used. Query this, and the case often began to fragment. eDNA has its own issues too. So, yes in principle to advances in technology, but yes also to clear health warnings and stated limitations in any planning submissions that use them.

What do you hope readers and practitioners will take away from your book?

The main message is that good data is key to an informed discussion between developers, opponents and planners. Being able to see what is needed, how it might be done, and why the precepts of BS 42020 (Biodiversity Standard) are core to the process. Openness, transparency and knowing what is needed will help us all – and biodiversity in particular. Poor data, bad methods and doubtful claims won’t help. If this guide helps LPAs pick some of those up, then it was worth writing.

Finally, what is occupying your time at the moment? Are you working on any other projects we can hear about?

Although now largely retired, I continue to write a blog on matters that interest me: serious and whimsical. I’m standing down now from Chairing a Friend’s Group for an island nature reserve. Having written the management plan for the site, the dim and distant origins of the island intrigue me, and there are plans in the pipework for a small book on the history and ecology of the island.

The NHBS Guide to UK Grassland Fungi

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

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

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

Groups

Waxcaps (Hygrocybe)

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

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

Size: 5-7cm

Club and Corals (Clavariaceae)

Yellow club fungus. — Yellow club fungus by Jo Graeser.

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

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

Size: 4-10cm

Wood Pinkgill (Entoloma rhodopolium)

Brown caps of wood pinkgill mushrooms (Entoloma rhodopolium) in Huntsville State Park. Texas. — Brown caps of wood pinkgill mushrooms (Entoloma rhodopolium) via Texas Mushrooms.

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

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

Size: 3-5cm

Note: Poisonous

Species

Earthtongue fungi (Geoglossum fallax)

Earthtongues - Glutinoglossum by Lukas Large, via flickr. — Earthtongues – Glutinoglossum by Lukas Large, via flickr.

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

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

Size: 2-7cm

Common Inkcap (Coprinopsis atramentaria)

Inkcap Trio by Derek Winterburn, via flickr.

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

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

Size: 3-7cm

Note: Poisonous

Petticoat Mottlegill (Panaeolus papilionaceus)

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

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

Size: 6-12cm

Common Earthball (Scleroderma citrinum)

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

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

Size: 4-10cm

Common Parasol (Macrolepiota procera)

Parasol Fungi by Bernard Spragg, via flickr.

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

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

Size: 10-25cm

The NHBS Guide to UK Bracket Fungi

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

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

Chicken of the Woods (Laetiporus sulphureus) – also known as Sulphur polypore’

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

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

Size: 10-40cm

Hen-of-the-Woods (Grifola frondosa)

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

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

Size: Up to 70cm

Turkeytail (Trametes versicolor)

Turkeytail Fungi (Trametes versicolor) by Jo Graeser.

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

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

Size: 4-10cm

Beefsteak (Fistulina hepatica)

Identification: This bracket fungus can be pink, red or brown in colour, with a light underside full of pores that turn red with age. Featuring a slightly inflated edge that flattens as it matures, Beefsteak fungus is moist to the touch and produces smooth, round, pale pink spores.

Distribution: August to November. Usually found in broadleaved woodlands on oak trees.

Size: 6-25cm

Birch Polypore (Piptoporus betulinus) – Also known as the Razorstrop fungus

Identification: Birch Polypore is a common bracket fungus that grows exclusively on birch trees. It has a rounded, brown-white cap with a rubber or leather-like texture and white pores on its underside.

Distribution: It can be found year-round on the lower trunk of birch trees and fallen birch branches.

Size: 10-20cm

Dryads Saddle (Cerioporus squamosus)

More Dryad's saddle. — Image by Andrew Hill via flickr.

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

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

Size: Up to 70cm

Southern Bracket (Ganoderma australe)

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

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

Size: Up to 60cm

King Alfred’s Cakes (Daldinia concentrica)

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

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

Size: 2-10cm

Horses Hoof (Fomes fomentarius)

Horse Hoof Fungi, Knole Park, Sevenoaks, Kent. — Image by Nigel Turner via flickr.

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

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

Size: 5 to 45cm

Parasol Mushroom by S. Rae via flickr. — Parasol Mushroom by S. Rae, via flickr.

In the early stages of the average mushroom-enthusiast’s journey, there comes a time where you begin to consider where you can take the interest of fungi further. Maybe you have identified all the mushrooms in your garden and want to learn more, or maybe you’ve even been intrepid, foraging and sampling some of the edible species out there, and are left wanting more. What ‘more’ looks like to some people becomes growing your own mushrooms, making spore prints, creating your own ink from the dripping tops of an inkcap mushroom, or perhaps you may want to look down a microscope to explore the sub-perceptual world of fungal microscopy, and that’s what these books aim to facilitate.

However you choose to flesh out your interest, the books below provide an excellent guide to the next steps in mycology.

Radical Mycology: A Treatise on Seeing and Working with Fungi

Radical Mycology is an awesome book in a very biblical sense. it inspires awe and in a more modern sense it is simply really, really cool. This book is a single man’s knowledge of all things fungi, distilled into 646 pages of rich prose, instruction and guidance. It moves through topics, that many other books have tackled in single volumes alone, in sections such as ethnomycology, culture, cultivation, medicine (*see footnote) and lab work, and does so in a way that doesn’t feel clunky or dense. I don’t think there is a topic in mycology that isn’t covered by this book in some way, and that to me makes it a unique treasure trove of knowledge. A field guide it is not, being quite large and very heavy, and it is not trying to pretend to be anything other than a treatise on the world of mycology. Filled with activities and projects that you can do yourself, it is not a passive book. It gets you interacting with and manipulating fungi, working with them in a way that you would not otherwise, and for that I think it is highly recommended for every reader, from the beginner to the professional. And if none of that takes your fancy, there is even a section on mushroom–related puns and a printout–and–play boardgame!

Growing Mushrooms at Home: The Complete Guide to Knowing, Growing and Loving Fungi

A more focussed look at cultivation and less dense than Radical Mycology, this book is primarily aimed at beginners who are looking to expand their knowledge of cultivation in its many forms, and is filled with simple, easy to follow text and beautiful images of mushrooms. It is designed to be accessible, so I would wager that this title is not suited for those of you with more experience in the field. But, for a first foray into mushroom cultivation this might be the book for you.

Organic Mushroom Farming and Mycoremediation: Simple to Advanced and Experimental Techniques for Indoor and Outdoor Cultivation

Organic Mushroom Farming and Mycoremediation takes a deeper dive into the same topic as the previous title. The book spans from easy projects that you can do at home with very little resources, to more advanced techniques that even the most experienced mycologist would enjoy having under their belt. The book also touches on mycoremediation (using mushrooms to improve the environment, from pollutants etc.), which is a wholly worthy topic on its own and will open your eyes to the potential for individuals to change the world for the better. After all, anyone who’s anyone in mycology has tried growing mushrooms on their old clothes, right?

Growing Gourmet and Medicinal Mushrooms: A Companion Guide to the Mushroom Cultivator

No list of mushroom cultivation books would be complete without a title by Paul Stamets – and this one is no exception. A dated publication now, owing to its original publishing in 1988 and subsequent re-prints in 1994 and 2000, have meant this this book has taken a back seat to the new shiny covers in the field. However, this has not dulled its brilliance at all, and it remains one of the most influential books on mushroom cultivation. The book contains foundational knowledge on mushroom cultivation for the amateur grower and is still held in high regard by anyone with a slight interest in modern mushroom cultivation. A must read and a true introduction to mastering the art of mushroom cultivation.ng mycologist.

* ‘Mushroom medicine’ is a term used often in fungal–oriented literature, and sometimes quite liberally. I would be remiss to note that processes, procedures and purported effects are anecdotal and not always backed up by peer–reviewed empirical research, and in a lot of cases research is ongoing. This is not to say it is not true, it’s to say that more research is usually needed. Be aware of the legality of foraging mushrooms in your area and remember, don’t munch on a hunch! Always ID your mushrooms and if you are not 100% confident consult a professional.

This Week in Biodiversity News – 4th November

Climate Crisis

Concern is mounting over the lack of progress made at COP16. After the historic agreement in Montreal which established targets to reform subsidies and to protect 30% of the planet by 2030, COP16 has revealed that participating nations are not on track to meet these targets outlined in the agreement. In order to reach 30×30, we must designate protected land equivalent to Brazil and Australia combined, and an area of the sea larger than the Indian Ocean. The second week of negotiations has shown little concrete progress on any of these targets, and a slow implementation of these international agreements risks another decade of biodiversity loss.

The UK’s largest supplier of farmed salmon has reported the biggest mass die-off in a decade. Mowi Scotland, a supplier to large supermarkets in the UK, has reported the loss of over one million fish in one production cycle. The supplier has attributed the loss to a rise in sea temperatures, exacerbated by the climate crisis, which give rise to jellyfish blooms – these harmful blooms can cause injury to farmed salmon, risking health issues and fatalities.

Conservation

The final phase of a £4.5 million rodent eradication project is underway on Rathlin Island, Northern Ireland. The island hosts one of the UK’s largest seabird colonies, including Puffins, Manx Shearwaters and Kittiwakes. Seabird species are suffering heavily from rodent predation, and Puffins alone have declined by 74% over a twenty year period. In October, the last of over 6,700 rodent traps were deployed across the 3,400 acre island and over the next seven months, conservationists and volunteers will continue to work on the eradication programme, which will come to an end in 2026.

West European Hedgehogs have been classified as ‘near threatened’ under the IUCN red list. Their populations have suffered significant declines over recent decades and are believed to have halved in more than 50% of its native countries, including the UK. A 2022 study found that British hedgehogs declined up to 75% in rural areas due to growing environmental pressures, including agricultural intensification and urban expansion. Further population declines could see this species under risk of extinction.

A project to remove invasive Stoats from Orkney has seen positive results in the islands biodiversity. The Orkney Native Wildlife Project began in 2019 to remove non-native Stoats which pose significant threats to ground-nesting birds and an endemic vole species. The project is the largest Stoat removal attempted anywhere in the world, with over 6,500 animals removed to date, and has helped to boost wildlife across the island – compared to 2019, curlew and Oystercatcher nest success is three times higher, Hen Harrier nesting success is at its highest, and Orkney Vole activity has increased by 200%.

Environment

More than one third of tree species are facing extinction. Over 38% of the planet’s trees are threatened in 192 countries, outweighing the cumulative number of threatened birds, mammals, reptiles and amphibians. Compiled by Botanic Gardens Conservation International (BGCI) and the International Union for the Conservation of Nature (IUCN), the work of over 1,000 scientists contributed to the assessment of the conservation status of trees. It found that logging, land clearing, pests and diseases were the greatest threats to the group, which could have a cascading effect on other animal and plant species that rely on trees for survival.

Two Bison calves have been born in Blean Woods. As part of the Wilder Blean Bison Project, managed by the Kent Wildlife Trust and the Wildwood Trust, a small herd of European Bison were introduced to woodland in Canterbury, Kent. Three females and one bull were released in 2022 to boost biodiversity and improve the resilience of the environment in the face of climate change. The birth of these calves now brings the herd to eight members, and conservationists hope that the group will continue to expand and benefit the biodiversity of their environment.

Top 5: Acoustic Recorders

Many animal groups use sound to communicate, whether this be for mating and courtship, navigation or general intraspecific communication. These sounds can come in the form of croaks, songs and calls, and are produced by a wide range of animal groups including amphibians, birds, mammals and insects.

Acoustic recorders allow us to listen to these sounds, whether this be for surveying and monitoring, or just for enjoyment. This non-invasive monitoring method allows us to gather data from an environment without disturbing wildlife, and some recorders are designed to be extremely sensitive, enabling users to capture sound from great distances. From these recordings we can identify species, analyse distribution, abundance, ecological community composition and even behaviour and can use the data to inform landscape management.

Author interview with Ursula Clare Franklin: Mission Penguin

Following the loss of her husband, Ursula Franklin embarked on a mission to see and photograph every species of penguin in their natural habitat. In this breathtaking book, join Ursula on expeditions to some of the most remote places on earth, from the Falklands to Tristan da Cunha and Antipodes Islands, in search of these much-loved birds. Interspersed with stories from Ursula’s adventures, each chapter explores a different species of penguin, detailing their identifying features, the ever-increasing threats they’re facing, and the conservation efforts needed to ensure future generations can experience the wonder of these animals.

Ursula Franklin is a keen wildlife photographer who grew up in Yorkshire, and is now based in Somerset. She developed a keen interest in photography when she was a child and her wonderful husband supported her passion until his sudden death in 2012. As a way to process her grief and heal, alongside her husband’s constant encouragement for her to ‘do something with her photography’, Mission Penguin was born.

We recently had the opportunity to talk to Ursula about her expedition, how she thinks we can we work to protect these vital species in the future, her favourite memories throughout this journey and more.

Having travelled around the world and seen every species of penguin in every habitat, which species surprised you the most and why?

Like many people, I had always associated penguins with snow, so it was amazing to discover that some species breed in forests, others in the desert and one species even at the equator. The species that really surprised me, however, and for a totally different reason, was the Royal Penguin. This species breeds on Macquarie Island, and in the north of the island are the rusted remains of huge digestors which were once used to extract oil firstly from seals and then when they ran out, penguins. Millions of King and Royal Penguins were slaughtered leaving just a few thousand birds when the barbaric practice was finally stopped. Having suffered years of persecution by man, I marvelled at how trusting the birds were. As I sat on the beach, groups of Royal Penguins waddled up to me, inquisitively studying my boot laces, camera bag and equipment. They were so curious and seemed utterly fearless. It was hard to imagine humankind betraying such trust. Luckily, over the last 100 years, their numbers have steadily increased and in 2022 they were finally taken off the list of near-threatened species (IUCN red list). Hopefully they will continue to increase despite the human-induced climate change crisis.

You were lucky enough to witness the full, daily lifecycle of a number of penguin colonies by watching them from dawn until dusk, and I particularly loved the photographs of the Gentoo penguins on Saunders Beach at sunset. What does the typical day in the life of a penguin look like?

A day in the life of a penguin varies hugely depending on the time of year, especially during the breeding season, or when moulting. At other times of year, the birds spend their time foraging in the open ocean. During their annual moult, which usually lasts around 3 weeks, they are no longer waterproof so cannot go into the ocean to feed – instead they must stay on land living solely off their fat reserves. The breeding season is when they spend time on both land and sea. For most species, males and females share incubation of the egg/s and often take it in turns to go foraging to feed the hungry chick/s whilst the other parent stays to protect it/them. With some species, as the chicks get older, they are left in a crèche, or some stay in a burrow, allowing both parents to go to the ocean to collect food for their increasing appetites. The birds often leave at dawn when foraging, and the length of time they are away depends on how far they must swim to find food. For some species, warming ocean temperatures have shifted prey populations further from the colony leading to chick starvation and mass breeding failure. When the parents do return with food, some species engage their older chicks in long food chases before finally stopping to feed them. This is done to build up the strength of the chicks prior to fledging and is hilarious to watch. The adults then stay with their chicks at the colony overnight before the whole process starts again early the next morning.

You travelled around the world and have seen so many different places as a result of this project – what was your favourite memory and why?

This is such a hard question. I could say the very beginning of the mission on the Antarctic Peninsula with the sighting of my first penguin – this was a Chinstrap Penguin and has since become my favourite species, probably because the black strap under their chin makes it look as if they are smiling. Or I could go to the very end of the mission at Snow Hill Island with the Emperor Penguin colony, which was like being on the film set of the movie Happy feet and a very fitting and emotional accomplishment of Mission Penguin.

My favourite travel destination, however, is the Falkland Islands. With fewer than 4000 people, beautiful coastlines and over one million penguins of five species I’m sure you can understand why. My favourite island is Saunders Island and my favourite location there is ‘the neck’. The accommodation is very basic and although small can technically sleep 8 in 4 sets of narrow bunk beds. Incredibly, on my last visit, my friend Hazel and I were the only occupants – apart from the penguins of course! What a joy and privilege to be the only humans sharing their world and a memory that will stay with me forever.

Having witnessed first-hand the negative effects of both climate change and human activity on penguin colonies, and their respective habitats, how can we work to protect these vital species in the future?

Penguins are key indicator species for the health of our oceans and the effects of global warming. Although there are no penguins naturally occurring in the Northern Hemisphere, our everyday actions here will ultimately filter down to the Southern Hemisphere and affect these animals.

One of the most threatened penguins is the African Penguin, and research suggests that this species could become extinct in the wild by 2035 unless we act now. Whilst we have little influence on African governments regarding marine ‘no-take’ zones, limiting coastal development, (oil refineries etc) can still help. For example, all of us can reduce our use of plastics (especially single use), and switch to renewable energy sources.

For more direct and immediate help we can also sponsor penguin nest boxes. African Penguins naturally lay their eggs in burrows which are dug out of layers of guano (bird poo!) laid down over hundreds of years. In the 1800’s most of this guano was collected and shipped to the UK to be used as fertiliser. As a result, there has been a 99% decline in the population over the last 100 years. As land temperatures continue to rise, penguins now nesting out in the open air are either dying from hyperthermia or abandoning their nests to save themselves, leading to mass breeding failure. Carefully researched and crafted nest-boxes that replicate the conditions of a guano burrow are proving effective – to help visit the Saving Penguins website.

A shortage of suitable nesting sites mean breeding African penguins are exposed to the full heat of the sun often with disastrous consequences.

Photographing every species of penguin is no small feat, especially alongside a full-time job! What were some of the biggest challenges you faced and what did you learn along the way?

When I announced to a friend that I was going to photograph every species of penguin in their natural habitat, I had no idea how many species there were or where they could be found. My research took me to places that I had never even heard of and to say many of them were ‘off the main tourist route’ would be an understatement! Simply getting to the required and often incredibly remote locations was definitely the first challenge. Many of these are also found in the roughest oceans in the world, and I suffer dreadfully from sea sickness. Needless to say, I was often very unwell but even that could not detract from the awe and wonder of these amazing expeditions. Once at the location, sometimes I only managed fleeting glimpses of just a few penguins of that species so not many photographs, but I appreciate how very lucky I was to actually see and photograph every penguin species on the first attempt.

The weather also presented significant challenges (especially the wind), and trying to photograph from a Zodiac (Rigid Inflatable Boat) while being tossed around in large swells was at times nigh on impossible. I also needed to keep my equipment warm in Antarctica and dry in the humidity of the Galápagos. Sunshine, although lovely in itself, also made photographing black and white birds more difficult than normal in terms of achieving correct exposure. I certainly learned to tolerate imperfections but also became a better photographer along the way. I also witnessed firsthand how tenacious and resilient penguins are – characteristics that we can all learn from.

The strong wind blowing the crests of these Moseley’s rockhopper penguins also made photographing them more challenging.

Mission Penguin came to fruition as a result of loss and grief, and throughout the book I found it heartwarming to read about the healing effects of your expeditions. How important do you think nature is in healing from grief, and what are the benefits of spending time exploring the natural world?

Nature is indeed an incredible healer. I have lovely memories of my mother taking us out on nature walks when we were young as we didn’t have much money, and nature was all around us and free! I think from that age I learned to appreciate the wonder of nature and delight in simple things, so when grief struck, getting out in nature and reconnecting with life and beauty was essential to my healing. Nature stimulates all of our senses which certainly helped me to feel fully alive even in the context of death. What inescapable joy to hear the birds singing, see the dappled light in a woodland glade, smell the flowers, taste the salty sea air, and hug a tree! Being immersed in the natural world really helps to put things into perspective and to feel part of something much greater than ourselves. In nature I feel fully grounded which gives me an inner peace and the strength to keep going, one step at a time.

What’s taking up your time at the moment? Are you working on any other projects or planning any upcoming expeditions that we can hear about?

Following the completion of Mission Penguin I have spent more time delighting in the natural world on my doorstep. In the last couple of years, I have finally taken up gardening, which my husband would have found hysterical having tried to persuade me all our married life! My focus however is gardening with wildlife in mind, and I think we would have had very different definitions of a ‘weed’! I am also rewilding one large area and quickly learned the hard way that rewilding is not the same as letting things go wild! I am still taking lots of nature photographs and readers can see more of my images here.

As well as writing the book, I started giving talks on Mission Penguin to local groups and this quickly expanded to other topics as they keep inviting me back for more. I now have about 6 talks in my repertoire so that is keeping me busy as well as continuing with my singing – another fabulous activity for wellbeing.

I am a firm believer in making the most of every moment. We only have one life, so live it well. Fill it with friends, joy, laughter – and of course, penguins.

Material Guide: Woodcrete

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.

Manufacturing process

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.
