*****A unique on the story of dinosaur extinction and its aftermath
The day an asteroid slammed into the Yucatán Peninsula some 66 million years ago is a strong contender for “the worst day in history”. The K–Pg extinction ended the long evolutionary success story of the dinosaurs and a host of other creatures, and has lodged itself firmly in our collective imagination. But what happened next? The fact that a primate is tapping away at a keyboard writing this review gives you part of the answer. The rise of mammals was not a given, though, and the details have been hard to get by. Here, science writer Riley Black examines and imagines the aftermath of the extinction at various times post-impact. The Last Days of the Dinosaurs ends up being a fine piece of narrative non-fiction with thoughtful observations on the role of evolution in ecosystem recovery.
Before delving in, a brief word on what is not in the book. Black does not discuss the history of the research that discovered evidence of an asteroid impact, such as the iridium spike and the crater. Nor does she go into the ongoing debate on the relative contributions of the asteroid and Deccan Trap volcanism. Instead, Black’s approach is to imagine a day in the life of the survivors at various time points post-impact: after an hour, a day, a month, a year, a century, all the way up to one million years. She focuses on the Hell Creek formation in western North America as it offers one of the clearest windows into the mass extinction and its aftermath. Most chapters have a short coda that looks at how life was faring elsewhere on the planet. Black’s style of choice is narrative non-fiction: she is resurrecting individual animals and imagining their lives. As she explains in her preface, to allow full immersion, she is not interrupting the flow of her story with notes and references, which are found at the back of the book. An extensive, 58-page(!) chapter-by-chapter appendix reveals her process and discusses what we know, what is hypothetical, and where she has speculated to smooth over the gaps in our knowledge.
Now, when this book was announced, just the prospect of dipping into the story of the disaster and the ensuing recovery already had me excited. However, The Last Days of the Dinosaurs surpassed even these expectations for two main reasons.
First, there are plenty of exciting new ideas and scientific findings here. Black’s interpretation of the impact will no doubt ruffle some feathers as it is particularly catastrophic. Forget the often-depicted idea of an asteroid seen streaking across the sky, Black writes, this thing came in fast at some 45,000 miles per hour (~20 km/s). Forget, too, the often-depicted drawn-out hunger winter for the surviving dinosaurs. I had not come across this idea before, but Black writes how a global heat pulse that lasted several hours fried anyone that could not crawl underground or stay submerged underwater. This is based on estimates of the amount of material ejected by the impact that, upon re-entry, heated the atmosphere to several hundreds of degrees centigrade. It would have ignited global wildfires. Finally, the impact injected vast amounts of sulfate aerosols into the atmosphere as the impact site was rich in calcium sulfate. The ensuing acid rain “might have effectively erased some of the slowly forming fossil record” (p. 256), explaining why fossils are hard to find in the layers around the K–Pg boundary.

Regarding the survivors, Black has plenty of interesting ideas too. As seen at other times and other places, there was a fern spike. A rapid initial proliferation of ferns is frequently seen in devastated ecosystems where plants have died. And why did birds survive? One novel idea is that the survival of beaked, but not toothed birds is part of the answer. “Maintaining a mouth of sharp teeth comes with a reliance on animal food. […] A consumer that feeds on other consumers has very little to survive on now. But beaked birds do not face the same constraints” (p. 117). With the extinction of toothed birds and pterosaurs, the beaked birds were poised for an evolutionary radiation. Something similar happened with the mammals. Black prominently mentions the idea that Elsa Panciroli promoted in Beasts Before Us, that “it was competition between mammals that limited the number of different forms and niches Mesozoic mammals evolved into” (p. 158). With the extinction of more archaic mammaliaformes, the placental and marsupial mammals would flourish.
The second reason the book surpassed my expectations is Black’s reflections on the process of evolution and its role in ecological recovery. This is where her prose sings in places. One thousand years post-impact “[…] there is no script for what’s about to unfold, no cast of characters that inevitably must be filled” (p. 142). One million years post-impact a reptilian resurgence seems unlikely, but “the rise of the mammals is anything but assured […] When a global disaster ends one evolutionary dance, shifting the tempo, another begins, with no certainty as to who will lead” (p. 182). She poignantly notes how the fossil record “is not in any way a complete record of life on Earth. It is a record of fortuitous burials” (p. 254). And on the process of evolution, she writes how variation and happenstance provide “the raw material for natural selection and other evolutionary forces to shunt down different pathways. Not that there is any intent to this. It’s a passive state, a constantly running routine that is merely part of existence itself” (p. 196). This is music to my ears and Black’s writing is one of the highlights of this book.

Writing about such an iconic event carries the risk of intense scrutiny. No doubt, some experts and other palaeo-nerds will disagree with some of the details presented here. I think her appendix is sufficiently explicit about where she speculates and where she has chosen not to hedge her bets on different explanations. I was willing to read the book in this spirit, as one possible interpretation of how things might have unfolded, though one that Black carefully backs up with scientific evidence. My quibbles are rather minor instead. One is that the book has no index, the other is that there are no notes to the appendix. Relegating the discussion of the underlying science to the appendix is a defensible choice. But not properly referencing the studies mentioned here is, to me, a minor blemish on an otherwise excellent book.
If you have any interest whatsoever in dinosaurs and their extinction, this book comes highly recommended. Her take on the topic, dipping into the extinction and recovery at various moments post-impact, is novel. I am not familiar with other books attempting this. As a bonus, I expect that many readers will come away with a better understanding of the process of evolution.
In The Accidental Garden, author Richard Mabey takes the reader on a journey through his own garden in Norfolk and explores the possibility of nature becoming humankind’s equal partner. He watches as his ‘accidental’ garden becomes its own director and reorganises itself in its own way, with ants sowing cowslips in their own patterns, roses serendipitously sprouting amid gravel, moorhens nesting in trees and other fascinating interactions.
Richard Mabey has authored 30 books since becoming a full-time writer in 1974, a number of which have won awards, including the East Anglia Book Award, National Book Award and Whitbread Biography Award. He sat on the UK’s Nature Conservancy Council in the 1980s, has been awarded two Leverhulme Fellowships and three honorary doctorates, and became a Fellow in the Royal Society of Literature in 2011.
We recently had the opportunity to talk to Richard about his most recent book, where we discussed his approach to garden ‘by’ wildlife and the challenges he faced, the extent to which nature can thrive itself when human involvement is minimised, projects that are currently occupying his time and more.
Can you tell us what inspired you to write The Accidental Garden?
I’ve been meditating on many of the book’s themes for a long while – the paradox of our seeming new respect for nature co-existing with an obstinate reluctance to relinquish control; our obsession with tree-planting, as if trees have lost the ability to reproduce themselves; the lust for tidiness over vitality. What sparked the book – and set it in the theatre of our own garden – was a Dark Bush-cricket singing at midnight from the hollyhocks on that hottest-ever day in July 2022. It sounded like an anthem of hope.

You mentioned in the first chapter that you try to garden ‘by’ wildlife as much as for it. Have you faced any challenges while using this approach, and what tips would you give to someone who wants to try and garden by the wildlife and biodiversity found in their own patch?
The Accidental Garden isn’t an advice manual. It’s a hesitant, personal account of what happened when we opened the gate to what I call ’parallel development’ in our space. We do what humans do in gardens, and allow other organisms to do what they want. Allow them to become subjects rather than objects, and effectively become fellow gardeners. So I left the bramble patch be, instead of digging it up to plant some runtish nursery-forced oakling. Result: Field Maple and Hazel saplings growing through its protective thorniness. I kick bare patches in the grass and see what self-seeds. Broomrapes, Heartsease and Bee Orchids have been among the surprise settlers. If you’re prepared to junk judgemental labels like weeds and pests there are very few challenges from this approach.
There seems to be evidence that, if left to fend for itself, nature can thrive and colonise without human involvement, as seen along the Dorset coast in the 1800s. What do you think humankind can learn from this going forward?
I’m continually amazed that we find nature’s ability to thrive and adapt surprising. How else could the planet have supported an abundance of life for billions of years before humans arrived on the scene? The natural world has never lost that enterprise and agility. Our reluctance to take advantage of this, to capitalise on adaptive solutions to environmental change, is a typically arrogant stance by our species, still stuck in its ‘dominion over’ mode, and our loss, as well as the natural world’s.
As you mentioned in one of your chapters, many people relish how non-native plant species can transport you to other places, while they also play a key role in garden biodiversity and over time can become at home in the UK, as seen with Snowdrops and Horse Chestnut. How do you think we can nurture the inevitable introduction of new species without this disadvantaging native plants?
The only visiting species we have any trouble with is Ground Elder, and otherwise our patch is developing into a resilient fusion garden. Native plants and animals form new communities with benign settlers. I’m writing this in May just feet from a large and dazzling patch of self-sown flowers that have established themselves in the gravel round the house, including Red Campion, Green Alkanet, Lamb’s Lettuce, Red Valerian, Hedgerow Cranesbill, Ox-eye Daisies. My interest is in the vitality and autonomy of this community (and its insect life – Hummingbird Hawk-moths are the stars!). But in terms of pure visual attractiveness it would match any herbaceous border. I’m also pleased by the way Turkey Oaks are regenerating in and beyond our patch of treeland, growing alongside the Wild Cherries and Ashes, and proving more resistant to deer browsing than English Oaks. Of course, many newcomers cause trouble away from their home ground. But in an environment that is being damaged so much by climate change, we need new species to keep a biologically rich tapestry of life here, in case our traditional species have trouble coping. ‘Nativeness’ has always had strict time limits, at both ends.

What was the most interesting finding that you came across while undertaking this journey with your own garden?
I think learning about eliasomes, the little parcels of fat on the ends of many seeds that are ants’ rewards for acting as beasts of burden. (They ferry the seeds to their hills and feed the fat globules to their grubs.) Our red ants’ hills are now like living standing stones and I like to think they are responsible for Cowslips now carpeting most of our grassland.
What do you hope the reader can learn from The Accidental Garden?
I’ve been astonished by the inventiveness of our fellow beings when allowed a little leeway to do their own thing. When we drop our paternalistic attitude, our belief that we know best what should live where. Gardens are often compared to theatres, with the gardener as writer, director, set designer rolled into one. Can’t they also be open stages where uninvited, unsupervised species and ancient processes of colonisation and decay can improvise their own landscapes? In the 20 years we’ve been here one half of our plot has transformed itself into a kind of common, with patches of treeland and open grass, and a total of over 150 wild plant species arrived largely of their own accord. A garden is only in the smallest sense a microcosm and metaphor for the planet. But in it it’s possible to glimpse larger lessons about neighbourliness and cooperation, and the fact that the natural world is not intrinsically a victim, in need of constant intensive care.
What are you occupying your time with at the moment? Do you have any other books in progress that we can hear about?
At my age I should be put out to grass. But I can’t stop thinking and scribbling. I’ve just finished an expanded new edition of my 1993 book on the cultural history of Nightingales, Whistling in the Dark, out next year. And I’m dogged by a fancy of tracing the wild thread in the art of nature (always my second subject) from the cave paintings in Derbyshire to Andy Goldsworthy’s spring-flower-enclosing snowballs. But maybe I should just be content to use my walking stick (my Instrument of Minimum Intervention) to scratch more patches in the grass.
The Accidental Garden is available to pre-order from our bookstore.
Unusual spring weather is affecting bird migrations. The Wood Warbler, Redstart and Pied Flycatcher migrate from sub-Saharan Africa to British oak woods every spring and depend on Oak Moth caterpillars to feed their young. In recent years, these caterpillars had already emerged and were pupating by the time the birds arrived, resulting in their chicks starving. This year, however, they are facing a new issue: as spring has been so wet and cold, many birds have not reached Britain yet, while those that have are having to search for food in cool weather and have not begun nesting. These shifts in long-term weather patterns are likely to continue to cause migration issues going forward due to their unpredictability.
The final Venezuelan glacier has been downgraded to an ‘ice field’ following large-scale glacial melt. This follows the loss of at least six other glaciers across the country in the last century due to an increase in global temperatures. In March 2024, researchers revealed that the Humboldt glacier had shrunk from 450 hectares to just two hectares. More recent observations show that, in the last two months it has reduced in size further to the area of just two football pitches. The latest projections suggest that between 20–80% of glaciers worldwide will be lost by 2100 as a result of climate change, with some of this loss already inevitable despite attempts to combat climate breakdown.

New record of Asian Hornet sightings threatens native pollination species. While Asian Hornets aren’t yet established in the UK, recent flooding and warm temperatures are increasing the risk of this species spreading across the country. Defra has warned that early detection and irradiation is the key to saving our native pollinator species who are known to feed on Honeybees. Since 2016, there have been 108 sightings of Asian Hornets, 56 of which were recorded last year alone. A further eight have been reported in the UK so far this year. Kent is on the front-line of the battle against this species with many of the UK sightings recorded in this county.
Pioneering project that makes eco-friendly concrete from crushed shells may be the answer to extreme flooding. A team at the University of Central Lancashire has developed an innovative, sustainable, permeable concrete made from recycled crushed scallop and whelk shells that would otherwise go to landfill when discarded by fishmongers. Trials are being undertaken in Blackpool to assess its effectiveness in gardens, footpaths and car parks, and early results are very positive.
Over 8,000 hectares of land ‘left to nature’ to increase biodiversity. This restoration project, run by Forestry England and supported by both Forest Holidays and the Government, will be implemented in four areas across the UK: Castle Neroche, Somerset; Kielder Forest, Northumberland; Newtondale, North Yorkshire and Purbeck, Dorset. The project aims to minimise human involvement, allowing nature to shape these forest landscapes itself. Andrew Stinger, The Head of Environment at Forestry England, stated that, although the team is uncertain how these areas will evolve once human activity is reduced, they are confident they will become more biodiverse with the help of reintroduction initiatives, aid flood mitigation, improve air quality, and restore soil health.

Study reveals that female Sea Otters are using tools to help preserve their teeth. Researcher Chris Law documented the moment that a female Sea Otter used a rock anvil to open the shell of its next meal, a type of behaviour which has previously been witnessed in very few animals. Further investigation revealed that, when there’s a decline in their preferred food, female Sea Otters have evolved to use tools to allow them to overcome their weaker biting ability when compared to their male counterparts, which allows them to consume alternative, larger prey without damaging their teeth.
Weevils are beetles belonging to the superfamily Curculionoidea. They are generally characterised by their elongated snout, or rostrum, although this is not present in all species. The similarly named Curculionidae family exist within this superfamily and contain the “true” weevils. These true weevils have long snouts and geniculate or sharply hinged antennae that end in small clubs. There are several other families of weevil including Belidae, the primitive weevils, and Anthribidae, the fungus weevils.
As of 2012, over 600 species of weevil had been recorded in Britain. The total number of species worldwide is unknown, but estimates suggest that there are between 40,000–97,000. They can be found in a variety of habitats including gardens, parks, woodland, farmland, heathland and wetlands. They are usually found on plants but they can also be found on the ground. Some weevil species, such as vine weevils and rice weevils, feed on grains and can become an infestation inside pantries and cupboards. They aren’t harmful to humans or pets but they can cause damage to stored foods as their populations grow rapidly once they are inside containers of flour or cereals.
Identification of weevils can be difficult in the field as many species look alike to the naked eye. A hand lens, specimen pots and a good field guide can help. There are several ways to look for specimens, such as using a sweep net or beating tray or simply searching by eye. However, as weevils are very small, often less than 6mm in length, it is important to be careful when surveying.
In this post we will look at some of the most commonly found weevils in the UK, providing some key identifying features and information on similar or confusion species.
Glossary
– Elytra – Protective wing-cases covering the hindwings (singular, elytron)
– Geniculate antennae – Antennae having elbows
– Pronotum – Section of the body directly behind the head
– Rostrum – Snout-like projection extending from the head
– Scutellum – Large triangular shield or plate located on the back
– Setae – Stiff bristle-like hairs (singular, seta)
– Striae – Longitudinally depressed lines or furrows (singular, stria)
– Tarsi – Foot or contact surface of the leg (singular, tarsus)
– Tibia – Fourth segment of the leg (from the body), located between the femur and the tarsus
Distribution: Widespread throughout Britain. What to look for: Black body mottled with small brown patches. Their elytra, the hardened forewings that serve as protective cases for the hindwings, have longitudinal grooves, or striae. Their pronotum is pebbled in texture. Similar species: There are several dark, grooved species, and the Large Pine Weevil (Hylobius abietis) is visually similar but has orange or creamy-yellow spots resembling bands and their elytra lack defined grooves.

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

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

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

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

WILLOW GALL WEAVIL (Archarius salicivorus)
Distribution: Widespread in Britain. What to look for: A short, black weevil with a tapered body and long snout. Its antennae are midway along the rostrum. It has a paler underside and a small pale scutellum, the small section of the exoskeleton in the middle of the back between the pronotum and the abdomen Similar species: The Strawberry Blossom Weevil (Anthonomus rubi) is visually similar but has a less rounded appearance when viewed from above and a less barrel-shaped pronotum than the Willow Gall Weevil.
Large Pine Weavil by gbohne via Flickr (CC BY-SA 2.0)
LARGE PINE WEAVIL (Hyblobius albietis)
Distribution: Widespread. What to look for: This is a large dark brown weevil with orange to creamy-yellow patches on its elytra, which form bands. They have black or deep red legs with a distinct tooth on the femora and at the end of the tibiae. They also have eyebrow-like patches on their head at the base of their rostrum. Similar species: The Vine Weevil (O. Sulcatus, see above) is also dark with lighter patches, but these are brown and their elytra have more distinct striations. They also have a more distinctly ‘pebbled’ pronotum.
Caterpillars are part of the life cycle of moths or butterflies which is known as complete metamorphosis. This life cycle includes four stages: egg, caterpillar (also known as the larval or feeding stage), pupa (the transition stage) and adult (the reproductive phase). With over 2,600 species of moth and 60 species of butterfly in the British Isles, there are a large variety of caterpillars present in our countryside.
There are several stages of caterpillar growth called instars, during which the caterpillar sheds its skin as it grows. Colouration, size and patternation can vary between these instars. Additionally, species can have different variations of caterpillars, including different colour forms. Several species are listed below, grouped by key characteristics such as colour, patternation and features.
Hairy caterpillars
There are many ecological functions of hair-like structures on caterpillars including defence and camouflage. These hairs, called setea, can be almost invisible to the naked eye, while others make them easier to see. Two types of caterpillar hair can cause harm to humans and pets: urticating, which are itchy, non-venomous hairs that can irritate the skin, and stinging hairs, which are hollow spines that have poison-secreting cells that can cause a range of health issues if they enter the skin.
Knot Grass moth (Acronicta rumicis): Colour can vary between light gingery brown to near black, with patches of rusty brown hair and a broken line of white dorsal patches. They also have a wavy white line on their sides, broken with bright orange/red spots. They grow up to 40mm in length. Can be confused with the caterpillars of Brown-tail and Yellow-tail moths. Foodplants include Knot Grass as well as Broad-leaved Dock, plantains, Bramble, Hawthorn, Common Sorrel, heather, and Purple Loosestrife.
Fox Moth (Macrothylacia rubi): Very hairy, up to 70mm long, dark brown with an orangey stripe down the length of its body. Caterpillars in earlier stages of development may have distinctive orange or yellow bands. Commonly feeds on heathers, Bilberry, Creeping Willow, Bramble, Meadowsweet and Salad Burnet.
Garden Tiger moth (Arctia caja): Also known as the woolly bear caterpillar due its very long hairs. Grows up to 55mm long and has a dark red dorsal area with white tipped hairs,an orangey red underside, and small white markings along its sides. Feeds on a variety of herbacious and garden plants including Common Nettle, Broad-leaved Dock, burdocks and Hound’s-tongue.
Brown-tail moth (Euproctis chrysorrhoea): Can measure up to 30mm long, black with white markings down its sides and two distinctive orangey red ‘warts’ on its back near its tail. Be aware that its hairs are toxic to humans. Feeds on plants in the Rosaceae family including Hawthorn, Blackthorn, Plum, Cherry, Rose and Bramble.
Miller moth (Acronicta leporina): Up to 35mm long with very long white or yellow hairs that swirl to one side. The body is often a pale green to brown depending on the development stage but this can be hard to see under the hairs. Usually found on birch or Alder trees.
Pale Tussock moth (Calliteara pudibunda): Greenish yellow hairs with a black body showing through in bands between tufts. The hairs can vary in colour and can be white, brown or pink. They also have a tail tuft that varies in colour but is usually brown, pink or red. This can be absent in some individuals. The four, tussocky tufts on their dorsal are frequently white, brown or yellow. Feeds on a variety of broadleaved trees and shrubs including Hawthorn, Blackthorn, Crab Apple, oaks, birches and Hazel.
Sycamore moth (Acronicta aceris): Up to 40mm long with thick hair that is either yellow, brown or orange . They have bold white spots down their back, outlined in black, as well as tufts of dark orange or bright red hair on their back. Foodplants are most commonly Sycamore, Field Maple and Horse-chestnut.
White Ermine moth (Spilosoma lubricipeda): Approximately 40mm long with a red, orange or pale dorsal line. Caterpillars at later development stages are covered in spines that can be reddish brown, dark brown or even black.
Elephant Hawk-moth (Deilephila elpenor): Thick bodies that grow up to 8cm in length, usually dark brown but bright green forms also occur. The name derives from their smaller, trunk-like head that extends from its more bulbous neck. They feature a spiked tail and four eyespots, although the second pair can be less visible on darker individuals. Most frequently found on Rosebay Willowherb, Great Willowherb, other willowherbs and bedstraws.
Square-spot Rustic moth (Xestia xanthographa): Greenish ochre in colour, with pale lines on its back and edged with dark, long, slanted markings on its sides in a row. Mainly feeds on grasses, plantains and Cleavers.
Large Yellow Underwing moth (Noctua pronuba): Grows to a length of 45–50mm. Its body can be various shades of brown and green, with three lines down its back and dark patches on the inner side of the outer two lines – similar to the Square-spot Rustic. They also have darker sides with a lighter stripe above the legs. Feeds on a wide range of herbaceous plants and grasses including docks, brassicas, marigolds and Foxglove.
Dot Moth (Melanchra persicariae): These caterpillars can reach up to 45mm in length and can be different shades of brown and green. They have three pale, distinctive lines on the dark prothoracic plate behind their head, as well as dark and light chevrons along a pale dorsal line down their backs. Feeds on a wide range of herbaceous and woody plants including Common Nettle, White Clover, Ivy, Hazel, Elder and willows.
Many of these caterpillars can also have a green form.
Large White butterfly (Pieris brassicae): Pale green-yellow in colour with black spots along its body. Visibly hairy. Also known as a Cabbage White due to its preference for cabbages as a food plant.
Buff-tip moth (Phalera bucephala): Distinctive caterpillar with a trellised black and yellow patterning and covering of pale hairs. The face is black and has an inverted yellow V. When fully grown this caterpillar measures up to 75mm in length. Most frequently found on sallows, birches, oaks and Hazel.
Six-spot Burnet moth (Zygaena filipendulae): Caterpillars feature a series of yellow and black dots on a green or greenish-yellow body. Feeds on Common Bird’s-foot-trefoil or occasionally Greater Bird’s-foot-trefoil.
Small Tortoiseshell butterfly (Aglais urticae): Caterpillars are initially black but show increasing variation in colour, with many developing pale yellow lines down their back and sides (some, however, may remain pure black). They have small clusters of short yellow spines and are fully grown at 30mm. Usually found on Common Nettle leaves.
Mullein moth (Curcullia verbasci): One of the most striking and distinctive caterpillars to be found in Britain, they have a mixture of repeating black and yellow markings on a pale bluish-grey body. When fully grown they measure almost 50mm in length. Foodplants include mulleins, Common Figwort, Water Figwort and buddleias.
Box Tree moth (Cydalima perspectalis): Box Tree moths were introduced accidentally from south-east Asia and are a pest of Box trees. Caterpillars have green and black stripes running the length of the body, and the head is shiny black. Each of the body segments has white hairs and eyelike markings.
Peacock butterfly (Aglais io): Unlike the brightly coloured adult Peacock butterfly, the Peacock caterpillar has a velvety black body with small white spots and short spines on each segment. Most commonly feeds on Common Nettle and Hops.
Painted Lady butterfly (Vanessa cardui): Often found on thistles, Painted Lady caterpillars live for 5-10 days in a loosely woven silk nest inside which they feed continuously. They have dark bodies with pale narrow yellow-cream stripes. Particularly on younger larvae, spines can be alternating light and dark.
Marsh Fritillary butterfly (Euphydryas aurinia): Caterpillars are black and hairy and initially live in groups on a larval web which is woven on the bottom-most leaves of Devil’s Bit Scabious plants. Prior to pupation, at the end of April, caterpillars will finally disperse to live independently.
Red Admiral butterfly (Vanessa atalanta): Caterpillars are black and spiny with a yellow stripe down each side and fine hairs along the body. They can be tricky to spot as they use silk to bind nettle leaves together to make a protective tent inside which they feed.
Lime Hawk-moth (Mimas tiliae): Caterpillars are distinctive having a large green body with pale yellow streaks on each segment and a bluish ‘horn’ at the tail end. Turns purple a short time before pupation. Foodplants include Limes, elms, Downy Birch, Silver Birch and Elder.
Poplar Hawk-moth (Laothoe populi): A thick and chunky, bright green caterpillar with faint yellow lines running diagonally along the body. The tail end has a yellow ‘horn’ and some individuals have small, dark spots. Food plants include poplars, sallows and willows.
Privet Hawk-moth (Sphinx ligustri): Bright, lime-green caterpillar with white and purple stripes and a pale yellow spot on each segment. The tail end has a black curved hook. Usually found on Wild and Garden Privets, Ash, Lilac and Guelder-rose.
Eyed Hawk-moth (Smerinthus ocellata): Closely resembles the Poplar Hawk-moth caterpillar in that it is bright green with diagonal yellow lines. When mature it can be distinguished by its bluish tail horn. Foodplants include Apple, willows and sallows.
Speckled Wood butterfly (Pararge aegeria): Bright green with faint dark green and yellow stripes running longitudinally along the length of the body. Feeds on False Brome, Cock’s-foot, Yorkshire-fog and Common Couch.
Pine Hawk-moth (Sphinx pinastri): Dark green caterpillar with a brown stripe along the centre of its back and cream dashes that run either side of this. It has a brown head and a black tail horn. Feeds mainly on Scots Pine.
Bright-line Brown-eye moth (Lacanobia oleracea): Green caterpillar with a bright yellow line along its sides and tiny black spots. Found on a variety of herbacious and woody plants such as Common Nettle, Fat-hen, willowherbs, Hazel and Hop. Sometimes a pest of cultivated Tomatoes.
Hummingbird Hawk-moth (Macroglossum stellatarum): Caterpillars are mainly green and have a thick, cream-yellow stripe running along the sides with a white line above. The tail horn is black with a yellow tip when mature. Feeds on Lady’s Bedstraw, Hedge Bedstraw and Wild Madder.
Straw Dot moth (Rivula sericealis): Green caterpillar with two cream stripes running along the back creating a repeating hourglass pattern between them. Covered in long fine hairs. Not often seen, the caterpillars feed on a variety of grass species.
Silver Y moth (Autographa gamma): Relatively easy to identify as it has only two sets of prolegs (small fleshy stubs beneath the body) and a rear clasper which means it walks with an arched body. It has a green body with a series of white wavy lines which may be broken by pale circles in later instars. Feeds on a range of low-lying herbacious plants including bedstraws, clovers, Common Nettle, Garden Pea and Cabbage.
Kentish Glory moth (Endromis versicolora): Large green caterpillar with diagonal pale stripes on each segment. Usually found on Silver Birch and less often on Downy Birch and Alder.
Emperor Moth (Saturnia pavonia): Green with black hoops containing yellow wartlike spots. Common in scrubby places whether they often feed on heathers, Meadowsweet, Bramble, Hawthorn and Blackthorn, amongst others.
Angle Shades moth (Phlogophora meticulosa): Usually green but can be mixed with shades of brown and/or yellow. A fine pale line runs down the back and a pale band runs down the sides of the body. Foodplants include a range of herbaceous and woody plants such as Common Nettle, Hop, Red Valerian, Bramble and Broad-leaved Dock.
Swallowtail butterfly (Papilio machaon): Striking bright green caterpillar with black bands and orange spots. British Swallowtail caterpillars feed solely on Milk-parsley.
Cinnabar moth (Tyria jacobaeae): Easy to identify having bold gold and black stripes. Most commonly feeds on the leaves and flowers of Common Ragwort where they can be found in their hundreds.
High Brown Fritillary butterfly (Argynnis adippe): Black caterpillar with a checkered pale pattern and yellow/buff spines. Covered in fine black bristles. Feeds on Common Dog-violet and Hairy Violet.
Magpie moth (Abraxas grossulariata): Distinctive caterpillar with a creamy-white body, rows of black and white spots and an orange stripe that runs along the length of the body on the lower sides. Feeds on a range of deciduous trees such as Blackthorn, Hawthorn and Hazel as well as currant and gooseberry bushes.
Small Copper butterfly (Lycaena phlaeas): Slug-shaped caterpillar covered in tiny white hairs. Exists in two forms: a purely green form and a green and pink striped form. Main foodplants are Common Sorrel and Sheep’s Sorrel.
Comma butterfly (Polygonia c-album): Mainly coloured brown and black with a large white mark towards the rear end of its back. Preferred foodplant is Common Nettle.
Yellow-tail moth (Euproctis similis): Black caterpillar with a small hump behind its head. Two red/orange lines run along the back with a row of white markings wither side of them. They are covered in long black hairs and shorter white ones. Feeds on a wide selection of broadleaf trees and shrubs including Hawthorn, Blackthorn, oaks, roses, Hazel and willows.
Lackey moth (Malacosoma neustria): Large orange, blue and white striped caterpillars that are covered with fine orange hairs. Often feed in large groups on broadleaved trees and shrubs including Blackthorn, Hawthorn, cherries, Plum and Apple.
The 2024 SouthWest Marine Ecosystems (SWME) conference was held at the Plymouth Marine Laboratory in April. Running since 2007, the conference brings together organisations and individuals involved in research on and management of the marine environment to report on annual system changesin the south-west. The conference covers the oceanography, plankton, seabed and seashore, fish, seabirds, seals and cetaceans of the south-west. Alongside key trends and interesting occurrences fromthe past year, SWME also encompasses management themes: marine planning, protected areas, fisheries, water quality and plastic pollution. This year’s theme focussed on the interconnectedness of the environment and its management, demonstrating this connectivity through interaction and discussion between guest speakers. In this blog we provide a roundup of SWME 2024.
The first session began with a rundown of oceanography and weather conditions across the UK, setting the scene for our marine environment. The UK experienced an increase in mean air temperature and increased sunshine duration over winter. There was also a decrease in mean rainfall across the UK and record-breaking heatwaves – some of us may remember the scorching temperatures of June last year, a worrying 2–3°C anomaly.
From March 2024, a new bylaw prohibits the use of bottom towed gear in defined areas of 13 marine protected areas (MPAs). Hartland Point to Tintagel Marine Conservation Zone (MCZ), Cape Bank MCZ, Lands End and Cape Bank MCZ, South of Celtic Deep MCZ, Wight-Barfleur Reef MCZ, East of Haig Fras MCZ and Greater Haig Fras MCZ are the MPAs that will benefit from this designation in the south-west. Devon Wildlife Trust vocalised a desire for a ‘whole-site approach’ for MPAs in the region – managing the site in its entirety, not just where protected species or features are present.

The Devon Maritime Forum stressed an urgency to address issues surrounding water quality in the south-west. They reported that no single stretch of river was found to be in ‘good’ overall health in 2023 – with quality impacted by agricultural run-off, sewage overflows, climate change and urban diffuse pollution.The UK Government has pledged to invest £1.6 billion to improve the water quality of rivers, lakes and coastal waters. Investments will be used to tackle storm overflow discharges, treatment works pollution and water resilience. South West Water will also be investing £70 million to upgrade infrastructure to reduce discharges in the region.
Analysis of plastic pollution showed that polyethylene was the most common material in plastic waste and marine litter fragments. To tackle the issue of plastic pollution on a global scale, the Global Plastics Treaty is under negotiation, and is expected to be legally binding by 2024. The treaty will address the full life cycle of plastic products and aim to end the pollution by these materials worldwide.
Key points:
Higher average winter temperatures and sunshine, with decreased rainfall were observed in 2023
A new bylaw will prohibit the use of bottom-towed gear in seven MPAs.
The UK Government has pledged to invest £1.6 billion to improve freshwater and coastal water quality
The Global Plastics Treaty will be legally binding by the end of 2024, intending to end plastic pollution
Organisms
Plankton researchers saw a higher abundance of salps (a barrel-shaped pelagic tunicate), consistent with a general increase in filter feeders over the past 30 years. There was also an influx of Barrel Jellyfish strandings across the south-west, with the species accounting for 27% (467) of the annual total of jellyfish sightings. A new method of plankton sampling has been developed, called Automated In-situ Plankton Imaging and Classification System (APICS). This new technology will help to determine the impacts of environmental changes on plankton, allowing for long-term, broad-spectrum measurements of the group.
New observations have improved our understanding of Basking Shark behaviour, revealing that this species may remain in UK waters throughout winter, instead of migrating south as previously believed. Blue Sharks were also caught more readily than previous years, exhibiting a higher catch per unit effort (CPUE), with over 1,000 caught off the coast of Looe, in Cornwall. The UK had its first sightings of Smalltooth Sand Tiger Shark, with a 10-foot individual washing up in Lyme Regis, Dorset. Typically seen in tropical and temperate waters, the discovery of this species in the UK is indicative of the effects of climate change on marine megafauna.Atlantic Bluefin Tuna have also been returning to the south-west with most sightings between July and February. There has been a marked increase in catch rate (over 5,000 were landed in 2023) which has prompted the introduction of fisheries plans (see below).

Rat eradication has been hugely successful for a number of seabirds. On Lundy, Manx Shearwaters and Puffins have responded positively and have seen population increases in 2023, and Storm Petrels have recolonised the island. Razorbills and Guillemots are also recovering well and are breeding successfully without predation from rats. The south-west has luckily missed the worst of avian influenza, although some small gulls and terns were affected in Dorset last summer. However, Kittiwakes are having local productivity issues which is prompting concern, and several species of gull are experiencing significant declines: Herring Gulls, Lesser Black-backed Gulls and Great Black-backed Gulls have all experienced losses over 40%. The English Seabird Conservation and Recovery Pathway (ESCaRP) report was published at the start of 2024, highlighting the sensitivity of seabird species to a range of pressures. Vulnerability assessments were conducted to inform the recovery pathway, and the report has made recommendations for conservation measures to address negative impacts.

There are concerns over the impacts of climate change on Humpback Whales. Increasingly, we are seeing individuals which are choosing not to migrate and are instead remaining in UK waters. Researchers believe that these animals are not undertaking seasonal movements due to a lack of food resources during winter – demonstrating that decreased productivity at the base of the food chain can cause issues further down the line for other marine organisms.
Key points:
New technology will provide a greater understanding of the impact environmental change may have on plankton
Atlantic Bluefin Tuna and shark sightings have increased in the south-west, including the Smalltooth Sand Tiger Shark, never previously recorded in the UK
Rat eradication programmes have been hugely successful in protecting seabirds
Kittiwakes and a number of gull species are experiencing declines
Climate change is thought to be impacting Humpback Whale migration
Industry
The Crown Estate have announced plans to develop more offshore wind farm projects, generating an additional 4GW of electricity to contribute to the 50GW by 2030 goal. This additional capacity could power up to four million homes, contributing to the UK target of net zero by 2050. Large, floating platforms have been proposed to enable deployment in deeper water – installation further offshore provides more reliable wind resources, generating more power for the same installation on-shore. There have been assessments to prepare for the deployment of extensive offshore wind in the south-west – with pre-consent surveys run by The Crown Estate. Celtic Sea Power, owned by Cornwall Council, is supporting offshore roll-out and has identified areas for data collection in the region. There are three project development areas where aerial, geophysical, acoustic and LiDAR surveys are taking place to improve data collection, accelerating the programme. The Poseidon Project was established by Natural England to provide a sensitivity map across the EEZ (exclusive economic zone –a surrounding area of 200 nautical miles offshore, where the nation has jurisdiction over resources) through digital aerial surveys. Collecting detailed information on seabirds, marine mammals and habitats, the project aims to improve models of abundance and distribution for key species which may be impacted by offshore development.

Sardine and Anchovy stocks are reported to have had a good year, continuing to support fisheries in the south-west, while Sprat fisheries have slowed due to insufficient stock size and 0-group fish (fish in their first year of life). We can see that new fisheries are emerging in the region (e.g. Atlantic Bluefin Tuna quota of 39 tonnes), while other, more traditional stocks are declining (e.g. Edible Crab). Five fisheries management plans have been developed for bass, King Scallops, crab and lobster, whelk and non-quota demersal species – these plans are put in place to deliver sustainable fisheries while minimising negative impacts on marine species. Dogger bank SAC, The Canyons MCZ and Inner Dowsing, Race Bank and North Ridge SAC were protected from damaging fishing activity in 2022 by prohibiting trawls, seines, dredges and bottom towed gear – this bylaw seeks to protect cold-water coral reefs, seabed, sandbanks and biogenic reef.
Key points:
Offshore wind development is being accelerated by better data collection and availability, supporting the UK in reaching renewable energy targets
Some traditional stocks are declining, while new fisheries are emerging
Five fisheries management plans were introduced
Four areas of conservation concern were protected to prohibit bottom towed gear
This year’s conference was an enlightening insight into the marine ecosystem in the south-west and highlighted some inspirational conservation work undertaken by several organisations, and individuals, dedicated to this environment. The SWME YouTube channel has a selection of webinars and further information on the conference can be found on the SWME website.
The UK is home to seven native species of amphibian. Over the winter, these frogs, toads and newts have all been hibernating, but it will soon be time for them to venture out to their breeding ponds and pools. If you’re lucky, you will be able to spot them when you’re out and about.
In this blogpost we will provide you with some of the key characteristics of each species which will help you to identify exactly what you’re looking at. For those of you who are keen to find out more, we have also provided a list of field and identification guides at the bottom of the page.
Newts
Newts are members of the salamander family and have a lizard-like body shape. They are semi-aquatic, spending part of the year on land, returning to the water in spring to breed. Eggs are laid in the water where they hatch into tadpoles and then proceed to develop front and back legs, along with gills for breathing. They leave the water in late summer once their gills have been lost.
The three species of newt which are native to the UK are the Smooth Newt (Lissotriton vulgaris), the Palmate Newt (Lissotriton helveticus) and the Great Crested Newt (Triturus cristatus).
Smooth Newt:
Look for the pale spotted throat. Image by gailhampshire.
• Size: Grows to around 10-11cm in length. • Colour: Males brown/olive; females light brown. Belly is usually yellowy orange with black spots. The throat is pale with darker spots. • Skin Texture: Smooth • Habitat: Spring to early summer in ponds and pools (frequently found in garden ponds). Late summer under logs and stones near to water. • Other notes: The male has a wavy back crest during the breeding season.
Palmate Newt:
Look for the pale throat without spots and a dark stripe through the eye – this can help you to distinguish it from the smooth newt. Image by Laurent Lebois.
• Size: Grows to around 7-11cm; slightly smaller than the smooth newt. • Colour: Males olive brown; females yellowish brown. The throat is white/pale pink and does not have spots or speckling. The eye has a dark stripe running horizontally through it. • Skin Texture: Smooth • Habitat: During the breeding season (early March to late May) in shallow ponds, often in heathland bogs. During summer in woodland, ditches and gardens near to water. • Other notes: During the breeding season, the male palmate newt has a ridge running along its back and a tail which ends in a filament. Its back feet are also webbed.
Great Crested Newt
Much larger than the smooth or palmate newt, the male has a large crest which is broken where the tail meets the body. Image by Chris H.
• Size: Up to 15cm in length. Females may be even larger than this. • Colour: Dark brown or black with white/silver dots on sides. Underside is orange with black spots. Pale throat. • Skin Texture: Warty • Habitat: March to May in deep ponds with vegetation. Great crested newts often range further than smooth or palmate newts during the summer and can be found in gardens, ditches and woodland. • Other notes: The male has a very distinctive crest during the breeding season which is broken at the point where the tail meets the body. The crest also has a silver stripe.
Frogs
Frogs are short-bodied, tailless amphibians that largely lay their eggs in water. These eggs hatch into aquatic larvae, known as tadpoles, before metamorphosing into froglets and then adults.
There are two native species of frog in the UK: the Common Frog (Rana temporaria) and the Pool Frog (Pelophylax lessonae).
Common Frog
Keep an eye out for dark patches behind the eyes and dark barring on the back legs. Image by Erik Paterson.
• Size: Adults grow to 6-9cm in length. • Colour: Olive green to yellow-brown. Usually spotty or stripy with dark patches behind the eyes and darker barring on hind legs. • Skin Texture: Smooth and moist. • Habitat: From late February to early October in all sorts of ponds and pools. Common in gardens. • Other notes: Moves by hopping. Common frogspawn is gelatinous with black embryos and tadpoles are initially black but turn speckled brown. (This is a useful way of distinguishing them from toad tadpoles, which remain dark until development).
Pool Frog
• Size: Adults grow to 6-9cm in length. • Colour: Usually brown with dark spots. Light yellow back stripe. • Skin Texture: Smooth and moist. • Habitat: Currently only present in localised spots in East Anglia. • Other notes: Males have prominent vocal sacks on the side of the mouth.
Toads
Toads are characterised by dry-looking, warty skin and short legs. They usually move via a lumbering walk, as opposed to the hopping motion used by frogs. As with frogs, most toads lay their eggs in water. These hatch into tadpoles before growing legs and metamorphosing into the adult form.
Within the UK there are two native species of toad: the Common Toad (Bufo bufo) and the Natterjack Toad (Epidalea calamita).
Common Toad
The common toad moves with a lumbering walk and has distinctive bulges on the back of its head. Image by stanze.
• Size: Females grow up to 13cm whilst males are smaller and usually reach only 8cm. • Colour: Brown to grey-green. Paler on the underside. • Skin Texture: Dry-looking and warty. • Habitat: From late February in damp, shady spots near to breeding ponds. During the summer in woodlands, gardens and fields. • Other notes: The common toad has amber eyes with a horizontal pupil. Moves with a lumbering walk or small hop. Eggs are laid in strings in a double row. Upon hatching the tadpoles are dark and, unlike frog tadpoles, remain so until they develop.
Natterjack Toad
The natterjack toad has a yellow stripe down the spine. Image by Bernard Dupont.
• Size: Females grow up to 8cm whilst males are slightly smaller. • Colour: Pale brown/green, often with brightly coloured red or yellow warts. Yellow stripe down the spine. • Skin Texture: Dry-looking and warty. • Habitat: Coastal dunes and lowland heath, often in open, unshaded habitats. The natterjack toad is very rare in the UK. • Other notes: The natterjack toad has amber eyes with a horizontal pupil. Moves with a running motion, rather than hopping. Lays strings of eggs in a single row.

Half the world’s estuaries have been altered by humans, with 20% of estuary loss occurring in the past 35 years alone as a result of urban or agricultural land expansions. Ninety percent of this has occurred in rapidly developing Asian countries, whereas very little estuary loss has been noted in higher income countries within the same period. This is because waterway alterations in these higher income countries were made many decades prior during their own urban development stages. With much of the world now trying to undo this damage and rewild urbanised areas, countries are now investing in programmes to return these areas to wild mudflats and salt marshes which will increase climate resilience, replenish aquatic populations, reduce flood risk and aid nature’s recovery.

The introduction of new diseases via open import systems are destroying EU trees and crops, with outbreaks on the rise once again. This comes after a mutation of one of the major killers of Olive trees in Italy, Xylella fastidiosa, was detected in America and is now wiping out US vineyards alongside its Italian counterparts. New data has revealed that an average of 70 foreign plant diseases were introduced to the EU between 2015–2020, despite legislation being enforced to prevent their spread in 2016, and scientists are holding open systems accountable. According to international protocols, only 2% of imported plants travelling through open systems are inspected for the presence of diseases, meaning that an alarming number of plant pests may be brought into the EU undetected. Although some pathogens are harmless in areas where ecosystems have evolved alongside them, they can be deadly when introduced to a new area. As global temperatures continue to rise, the problem is only likely to get worse.
Conservation
A UK study has proven that wilder gardens boost butterfly population numbers, with long, uncut grass likely to almost double butterfly abundance. This research, co-authored by the head of science at Butterfly Conservation, recorded a 93% increase in butterflies in gardens within farmed landscapes who did not cut their lawns, while gardens in urban areas noted an 18% rise in population numbers. These wilder habitats attract species whose caterpillars live and feed on the grass, provide greater quantities of nectar that are necessary for butterfly survival, and create important breeding habitats, which subsequently increases population numbers. The study advises that long grass should be left until late September or early October before cutting as some species require longer grass nearly all year round.

Music featuring the sounds of nature earn royalties that will be donated to environmental causes. This new initiative, launched by the Museum for the United Nations, will recognise nature as an official artist on major music streaming platforms. A share of the royalties earnt when these songs are played will be donated to environmental causes and initiatives who are working hard to protect nature for the future. Nature itself will also have its own artist page on Spotify which will showcase ambient recordings of nature’s sounds, with 70% of the profits from these tracks funding conservation programmes.
The south coast’s only breeding Osprey pair have laid a fourth egg. These birds became the first nesting Ospreys on the south coast for 180 years after their reintroduction seven years ago. They returned to Poole Harbour in late March after their migration to West Africa and laid their first egg on the 15th April 2024. As female Ospreys usually only lay 3 eggs due to the challenges of feeding 4 young, researchers were surprised to find a fourth, but due to the exceptional job the pair did while caring for 3 chicks in 2023 they have high hopes for success this season.
Common Eastern Bumblebee queens have adapted so they can survive underwater for up to a week during hibernation, which is thought to be responsible for the species’ continual population stability, despite a third of all other bumblebee species currently in decline. This study was conducted as a result of water leaking into containers housing hibernating queens; results revealed that over 80% of the bees survived when submerged for up to seven days. Scientists noted that these findings are unusual as most overwintering insects cannot cope when submerged in water. However, it is hoped that this flood tolerance will help the species continue to thrive in the wild.

The largest snake that ever lived has been discovered in Western India, measuring up to 15m long and weighing a tonne. The fossil of the Vasuki indicus snake was discovered in a mine in western India and included 27 vertebrae, a few of which remained in the correct anatomical position. Scientists concluded that it would have lived in marshy swamps around 66m years ago during the Cenozoic era and, due to its size, it would have been a slow-moving ambush predator who attacked its prey through constriction.
Join author Kat Hill on a journey across England, Scotland and Wales to explore 15 remote bothies, and uncover the beauty, history and stories of these wild shelters. In this stirring book of adventure, peace, wilderness and refuge, she intertwines her own story of heartbreak and new purpose, while taking into consideration the environment, what we owe to it, and why we all crave escapes into the remote.
Kat Hill by Nicholas J. R
Kat Hill is a Senior Lecturer in History at Birkbeck College, London, and her current research project is focusing on questions of landscape, people, and heritage in the bothies of the Scottish Highlands, as well as non-conformist religious communities in Europe, America and the Global South. She holds a PhD from the University of Oxford in 2011, where she also received a British Academy Postdoctoral Award, and she authored the prize-winning book, Baptism, Brotherhood, and Belief: Anabaptism and Lutheranism, 1525-1585.
We recently chatted with Kat about what inspired her to write this book, how technology is changing the bothying experience, what she thinks the future holds for bothies and more.
Firstly, could you tell us a little bit about yourself and how you came to write a book about bothies?
I’m a writer and researcher living on the northern tip of the Isle of Skye. If I am not reading or thinking up project ideas, I am either out in the hills or beavering away at my other role, working with local communities for Highlands Rewilding. In my past life I was an academic historian (as well as an international Brazilian Jiu Jitsu competitor), but last year I took voluntary redundancy from academia to pursue my writing and creative practice more fully, as well as aiming to do something good for the world in an age of climate crisis and environmental breakdown. That need, to work on something to do with the living world, was part of the inspiration for writing Bothy. I’d grown weary of academic life, and London in particular, my personal life was a mess, and I felt disconnected and unsettled. And then I got invited to a bothy, Cadderlie to be precise, on the edge of Loch Etive.
When I first went to Cadderlie, I never intended to write a book about bothies. But I loved the whole experience, and the more I found out about them, the more drawn I was to these shelters. They embodied so many things I was interested in – landscape, our connection to place, environmental histories, material histories of people and the living world, and just generally being active and outside. Finally, the plans I had for quite some time to change direction and escape the life I was living came to fruition. Especially with that weird caesura that Covid provided, I had space to make notes and think, and in that time, I found the ability to write in a way I had not thought possible. I did an MA in Environmental Humanities alongside my job, kept chipping away at the work and was lucky enough to find an amazing agent. This book is not a memoir per se, though there’s quite a bit of my life in it, but I would say it’s a personal response both to the challenges of my own life and to the crises we see around us.
Were there any authors or books in particular that inspired you when you set out to write Bothy?
There’s a real mix of things that shaped my writing, as I am sure is the case for any writer, but one of the things I most enjoyed in the process was taking inspiration from an eclectic mix of authors and books. Too many to name, but I’ll give a flavour. Nature and travel writing has always felt like such an obvious go to. I remember my mum introducing me to Patrick Leigh Fermor’s A Time of Gifts when I was younger and his combination of learned observation and vivid writing about the world captivated me. Other travel writing like Steinbeck’s Travels with Charley always spoke to me. As for more recent nature/travel writers, I love Cal Flyn’s work, Rebecca Solnit, Judith Schalansky’s books, and Nick Hayes’ Trespass, and I have immersed myself in environmental writing from so many people. To name a few – Robin Wall Kimmerer, Anna Tsing, Kathleen Jamie, Robert Macfarlane, and Andri Snær Magnason.
But there were also personal elements to the book, and so when I was thinking how you deftly discuss your life and its meaning, it was to writers such as Deborah Levy, Amy Liptrot and Helen Macdonald that I turned. Fiction and literature shaped the work, too, novels like The Overstorey or Ursula Le Guin’s novels, short stories and essays. And I’ve always loved poetry, though I am not sure I am bold enough to write it for others – although, who knows? – and countless collections sit on my shelf, from Edna St. Vincent Millay to Alice Oswald, Rainer Maria Rilke to Liz Berry.
At the heart, too, I have always drawn inspiration from my academic background and academic writers, mainly historians and archaeologists, for example Natalie Zemon Davis, Tim Ingold and Jane Bennett, but also philosophers. If you don’t know Timothy Morton’s book Dark Ecology, then I highly recommend it. I also always looked to those whose work is accessible beyond the world of scholarly writing. I was given a great lesson in that by my academic mentor Lyndal Roper, a historian of sixteenth-century Germany, and at the back of my mind was always the sensitive, layered, textured approach she had to writing about past lives.
People find solace and healing in all sorts of activities and all manner of things. Why do you think bothies were the thing that helped you at a time when you needed it?
It was a particular mix of things that made bothies so meaningful for me. I’d not been to Scotland much before Cadderlie, so part of it was being able to spend time outdoors and simply be active in beautiful landscapes. I grew up in Shropshire, so especially when I went to the Welsh bothies it felt like I was rekindling a connection to the younger version of myself. But they also stirred the historian’s interest in me because in the bothies there are visitor books which are left for anyone to sign, and these are a startling, intriguing record of ordinary lives. Given the chance to write a poem, draw a doodle or write out a life history, most people do. I’ve worked so often with archival documents that give hints of past lives and material histories of human stories that these felt like such a rich source.
I felt an immediate connection to the people on these pages. And I loved that, because bothies arrived in my life at a turning point, when I needed that connection. It was a funny, difficult time personally for me when I found bothies. I was struggling with what direction to take, and I am not going to lie, the previous decade had been dark, difficult, and filled with depression and anxiety. On the outside everything looked great. I was doing really well in my academic career, I was living in London in Hammersmith, I was competing in, and winning, BJJ tournaments all over the world. But underneath was a bone-deep exhaustion. The long aftermath of a divorce and then the trauma of a difficult, fractious, toxic relationship had taken its toll. I found bothies as I came out of that. I entered a new relationship and prised myself away from the life that was making me unhappy, I loved some of the anonymity yet intimacy that bothies gave – you never know who’s going to be there which produces a strange kind of bond with fellow travellers- and the respite they provided from normal rhythms of life was welcome. You have to lead a pretty simple life with only camping gear and what you carry with you, even if that retreat into plain living is a manufactured choice.
This process for me wasn’t sudden and revelatory. One thing I talk about in the book is that you don’t just go out into nature and find a cure. But there’s little doubt that the company of the living world (and finding time for connection, consideration, and above all perhaps, play) is soothing and healing. Everyone’s bothy experience will be different but for me, in these places, I was able to reshape myself after a difficult decade as someone who was once again creative, outdoorsy, adventurous, a nature lover, kind to others- someone who was happy.

Do you think that technology and social media have changed the bothying experience?
For example, now you can discover the details and locations of individual bothies online and then use a GPS to find your way there with ease. I never knew bothies before they were on Google maps, blogs and Instagram, so that’s always been my experience of the bothy world. But it’s certainly easier to find them now than it was in the 1970s or 1980s. It’s a different world, but I guess the key question for lots of bothy users is whether that alters or fundamentally destroys the bothy experience. Some would say yes, and I understand the frustration. Influencer posts about the same tourist spots in the world are wearying. And there is a very important debate to be had about responsible access to landscapes and environments, or the damage we can do as tourists. Working as I do in the rewilding sphere part of the time, I am often at the sharp end of these conversations about the tensions between human and non-human interests in a place, local and non-local needs.
However, I also don’t think that all of the online stuff is bad in the bothy world. To survive, they need to be used and a new generation is part of that. Bothies are rooted in the desire for access to the countryside and in the working class ‘revolution’ for leisure and recreation in the hills that followed World War One. Expensive hotels and fancy tours were out of reach for working young men and women who suddenly had a bit more time for leisure, but bothies were free. So I find the private club notion of bothies, of pulling up the ladder after you, more than a little problematic as it seems to go against the idea of access and the right to roam.
Some bothies have shut due to claims of overcrowding and parties – though I have never really seen raucous behaviour myself – but it’s all too easy to blame people without a voice as the culprits. Without labelling all landowners as evil either, this is really a debate about rights to the outdoors, access and how we develop responsible, caring relationships to landscapes. I think bothies can be part of that.
Some bothies remain secret and I, for one, am not going to plaster them over the internet. But I have seen so many young people with a copy of Geoff Allan’s Bothy Bible in hand, loving the outdoors, and that makes me happy. I am sure information sharing has changed the experience of bothying but nothing is ever static in the world. Indeed, perhaps it’s a particularly human thing to be nostalgic for the moment just past, to get misty eyed about days gone by, rather than live in the present moment and to enjoy that for what it is. It makes me think of a line from an Office US episode from Andy Bernard: ‘‘I wish there was a way to know you’re in the good old days before you’ve actually left them.’
How important do you think isolation is to the spirit and experience of the bothy?
There’s a really touching story, I talk about in the book which comes from a bothy visitor book entry. A man has returned to a bothy which he used to come to with his wife, their last trip of such a kind before she died of cancer. For him, as for so many others, the bothy may be relatively remote and cut off from some of the comforts of modern life but it’s not isolation per se that makes it special. It’s fellowship, companionship, love. Of course, there is a kind of isolation. But isolation from what is the key, as it’s not from people and places in a secluded wilderness, often quite the opposite as you will normally meet a new acquaintance. Some people do love being in a bothy alone and I have had delightful, quiet evenings by myself or with just a friend, but also plenty of entertaining nights with strangers.
But even when you are alone, you aren’t really isolated because you are connected to the place around you, from the bothy mouse to the howling wind, to bellowing stags to querulous birds. Besides, bothies only exist because these were, and are, lived, worked landscapes. To imagine you are in an isolated wilderness is to do them a disservice.
What do you think the future holds for bothies? Will they forever be old stone buildings, or will they evolve to include less traditional and/or newly built structures?
I’d say bothies already are evolving in new ways and there are some new MBA bothies opening up, more cottages reclaimed and restored. I’d like to think there will always be stone bothies withy smoky walls and wooden floors because they have given me so much. But the bothy idea has been taken in many different directions: such as artistic residencies run by Bothy Project, or the wonderful Taigh Whin bothy and house run by partners Sarah MacLaren and Sophie Howarth, which offers low-cost holiday accommodation for people working for the common good – carers, community workers, teachers. This place (the house of gorse, it means) is a beautiful reimagining of the idea of shelter and connection in a bothy.
And then there’s the luxury tourism bothy which is pretty far away from a traditional bothy, but I guess in some ways draws on the ideas of simplicity and shelter. The idea of a hut, a shelter, a shieling is malleable and changing but also speaks to a basic need for refuge or rest. So, the idea continues to have power, increasingly so perhaps in a fractured and complex world. And there’s a future to the bothy there, not just a past. The delicate balance of past and present is at the heart of bothy life, the retreat from modernity whilst knowing that this retreat is in some way dependent on the contrast the simple life provides with the contemporary. If there was no city or phone signal to escape from then I think bothies would be a whole different prospect.
That’s why I think there’s a future for humble bothies of the stone wall variety, alongside the fancier versions, as they have lessons to give us about what matters. They ask us to question what we need, what makes us happy, and what we can do without.
Finally, what is occupying your time at the moment (professionally and/or personally)? And can we expect more books from you in the future?
Life has been really busy, professionally and personally. I’ve just moved to Skye so I am enjoying settling into the new house: filling up bird feeders, painting walls and walking to the beach. In between writing and reading, I have a part time role as a community engagement co-ordinator for Highlands Rewilding so I have been learning more and more about the practical implications of changing land use, climate change and the delicate balance between people and places.
I don’t think I can ever imagine not writing though, so there’s plenty of scribbling too, some articles and grant pitches but also new book ideas. There will definitely be another book! Having moved about 15 times in ten years, it’s wonderful to have a home again and that’s starting to shape my writing too. When I was working in academia, I did a tonne of research on Amish and Mennonite migrations, so maybe there will be something about home and finding our place in this world.
I am also embarking on a multiyear interdisciplinary project with photographer Nicholas J R White on places of shelter and refuge across the world, places where people stay for a short while. We’ve just got back from the Shiant Isles in the Minch, a beautiful place. Soft in summer, I imagine, but we were there at the time of the season’s changing when there’s still harshness in the air, winds cold, seas wild and sun shining. It’s already provided lots of food for thought. I am also out in the US later this year for a fellowship at the IAS at Princeton, so I might find my way up to some fire lookouts à la Gary Snyder and Jack Kerouac.
So, lots to keep me busy. Life is starting to settle again. I am in a happy place, surrounded by loving people. And I might even start some BJJ classes again.

Passionate naturalist, author and illustrator David Wege has led an exciting 30-year career in international bird conservation. Now sharing the joy of tracking through teaching, he aims to encourage others to deepen their connection with the world around us.
For his latest work, he has turned his attention to mammals and has created Mammal Tracks of Europe. After rediscovering his passion for tracking, David hopes to inspire others to engage with the art through his latest work. This book includes the tracks of 72 European mammals, with detailed drawings and portraits of each species.
We recently had the chance to chat with David about how he first became interested in tracking, why he included Homo sapiens in his new mammal tracks field guide, what he’s currently working on and more.
This unique field guide features a broad selection of European mammals. What criteria did you use when choosing which species to include?
I set out with the intention of creating a mammal tracks guide that anyone could take out into the field, anywhere in Europe, and identify the tracks they were looking at. This meant including all of Europe’s larger terrestrial mammals, including the Arctic species from Scandinavia (such as Wolverine, Arctic Fox and Muskox), and the species that have ranges just into the Mediterranean countries (like Crested Porcupine and Egyptian Mongoose). So, all larger European mammals that you are likely to find tracks of are featured.Even the domesticated species that, as trackers, we often find the tracks of– such as cats, dogs, cows, sheep and Alpacas! The small mammals (such as the mice, voles and shrews) are not covered quite as well, but all species for which we have track photos are included. The end result, is a book with the tracks and trails of an incredible 72 European mammal species.
Creating a book that anyone can use meant making it accessible to people right across Europe. So, each species is represented by a small portrait of the animal; is identified by its scientific name; and its common name is given in eightEuropean languages. As well as helping people navigate the book quickly, I think the species portraits make sure that we keep the connection between tracks and the animal that made them.
Tracking is increasing in popularity acrossEurope and is being used more and more as we rewild areas and reintroduce species in the region. My hope is that this guide will help encourage more people to connect with mammal tracks and engage with the conservation movement, wherever they are.
Why did you choose to include Homo sapiens in the field guide, and why were these tracks presented first?
Humans are part of nature.We’re mammals just like every other mammal in the book, so presenting ‘human’ in exactly the same way as our mammalian cousins – as Homo sapiens, a species that also makes tracks – seemed important. Connecting with nature starts with us recognising our place within it, so ‘human’ on Page 1 is a nod to our place as equals among other animal beings. There’s a practical aspect to this too. As a teacher passing on tracking knowledge to others, using our human hands and feet as a reference point for where toe pads, nails, palm pads, heels, carpal pads etc. are, is a great way for people to learn and relate to the track morphology of other mammalian beings. Human hands and feet (and the tracks they create) are a wonderful baseline against which we can start comparing the tracks of other species.
Instead of written descriptions, the field guide uses drawings as a primary aid to identification. What challenges did you face in illustrating the guide?
The guide really does have very little text and relies on drawings to do the talking – to be a graphic reference when you’re out in the field. I wanted to create precise representations of tracks for each species – to let the illustrations communicate all that was needed in a true ‘to be used in the field’ field guide. A noble desire, and easily said, but there really are many challenges.The first of which arises from the fact that no two tracks in the mud, sand, clay or snow are the same, so which one is best to illustrate? To overcome this, I ‘traced’ (electronically, on a tablet) as many track photos as possible to build up (as near as possible) a perfect average. This hopefully compensates for the vagaries of different substrates. Drawing from track photos means that those imagesneed to be good too!They have to be taken from directly above, with not too much shadow, and with a scale or ruler in the photo. When you start drawing from photos it really makes you appreciate which are good (and useful/usable) and which are not. Once I had my ‘good‘ track photos, I started drawing– trying to keep strictly to what I was seeing in the tracks. This has hopefully resulted in illustrations that allow people to pick out the identification features that are most noticeable to them.
Another challenge is that some of the species I’ve illustrated are rare, or from parts of Europe I have not been tracking, so I have had to rely on track photos shared generously by other trackers. It is definitely harder to illustrate a track that you’ve never seen in the field yourself – it’s difficult to get a ‘feel’ for the essence of it, but I think I’ve managed to create good representations of tracks for all the mammals.
Where did your initial interest in animal tracking come from, and how did you begin your journey into this field of study?
I was totally hooked on tracking as a child when my parents gave me a book–Nature Detective by Hugh Faulkus. However, without a tracking mentor, I actively pursued my other passion of birds and birdwatching – a passion that I still have and that led me to a successful career in bird conservation with BirdLife International. Then, about tenyears ago, I chanced upon a tracking mentor in John Rhyder (author of Track and Sign, and one of Europe’s foremost trackers), and have been learning from him and teaching with him ever since. We have just finished a book together titledBird Tracks: a field guide to British species. Tracking just seems like a natural component of being in nature for me. Wandering in nature means intuitively noticing who was there, doing what and when, which birds are calling or singing, what plants are emerging or flowering (and so much more). Reading the tracks is just a part of this awareness, although I’m still learning how to balance an awareness of tracks on the ground with noticing birds up in the trees!
What will be next for you? Are there any plans for more tracking guides?
One of the many wonders of tracking (by which I mean reading and interpreting the tracks and signs that animals leave on the landscape) is that there is always more to learn. Animals constantly surprise and we’re often discovering new behaviours revealed in tracks and signs. I’m still learning but I also have the privilege of teaching the art and science of tracking to others. So, I will be spreading the tracking joy, with my book in hand, to people who can hopefully then use the skill to connect to nature, or apply their tracking skills to help monitor, conserve and restore wildlife. This book was designed as a resource for people across Europe, but I would like to see my track and trail illustrations used for local or national field guides that might then be accessible to a wider audience. Anything to help encourage nature connection through tracking.
