Here we are, week three of #30DaysMacro as part of #30DaysWild. This week, things took a fungal turn after thunderstorms burst onto the scene.
Day 15/30: a bumblebee feeding on purple loosestrife in a car park in West Sussex. I took two photos all day on the 15th, and this was one of them!
Day 16/30: another day where photo opps were scarce, but I saw this little solitary bee (maybe a Colletes?) on the oxeye daisies in my garden. These daisies have been a massive boost to invert life in my garden this year.
Day 17/30: this photo made me laugh – a meadow brown butterfly on common knapweed in a Wealden meadow in West Sussex. I didn’t notice the green swollen-thighed beetle hanging out below until I put the photo through Lightroom!
Day 18/30: storms have been the only source of rain recently, and they have been incredibly powerful. After some of that rain, I went looking for some life in the garden and found a common planthopper with a little droplet on their head. I see this as pushing the camera (Olympus Tough TG-6 compact) to the extreme due to lack of light and small size of the subject, and the results are great (though cropped and edited in Lightroom).
Day 19/30: on a lunchtime walk to stretch my legs I found this ashy mining bee foraging from one of the umbellifers that grow alongside my local river.
Day 20/30: things took a turn for the fungal on the 20th, as the rain gave a much-needed drink to the thirsty lichens in my local churchyard.
Day 21/30: the first of the summer/early autumn mushrooms, spindleshank, growing in the place where I learned what they are at Sydenham Hill Wood.
On Saturday 12th November I led a fungi walk for London Wildlife Trust at Dulwich Wood in south-east London. I only managed one photo on the day because I was working and leading the group around, but it was a pretty good one nonetheless.
When doing a pre-walk check I accidentally flushed a woodcock from the vegetation off the main paths. I never like to do something like that but they are so difficult to see, camouflaged down there in the leaf litter. It’s good to know they are still able to use to woods as a stop off on passage. It also suggests they are using woods nearby which have no public access, because this is one that has hundreds of thousands of annual visitors, so ones free of ‘disturbance’ must be even better.

This isn’t new in Dulwich. Local ornithologist Dave Clark once told me a story of a woodcock smashing through someone’s window and landing in their bedroom. Because woodcock migrate, often by night, they sometimes get it wrong. Their long bills and speed of flight also mean they will crack glass quite easily. The bird in question was scooped up and taken to a vet, from what I remember it survived and lived to fly another day.
There’s a really nice episode of the Golden Grenades podcast featuring woodcock that you can listen to here. It features Kerrie Gardner, a superstar writer, photographer and sculptor who is a friend of this blog!
On the fungi front, the mushrooms were very few and far between considering the time of year. There was a shaggy theme to what was there, in that two of the sightings were shaggy parasol and shaggy bracket. The most common species group were the bonnets (Mycena), along with small polypores like turkey tail and hairy curtain crust, which are all on decaying wood.

My sense is that the extreme heat and drought this summer, where temperatures reached 40C, has had a worse impact in smaller woodlands in places like London. More rural, larger woodlands are able to hold water and moisture more effectively, therefore being able to feed fungal communities far more easily. Those woodlands also have running water in the form of brooks, streams and woodlands that aid soil moisture. London’s woods look far drier in November than those in West Sussex, even after torrential rain.
It’s also very mild, around 15-18 degrees on the 12th November, which shows just how far-reaching climate change already is. The milder weather may mean mushrooms fruit for longer though, with the colder temperatures held off until maybe January or February. It’s just so hard to predict these days.
One interesting thing that a couple of people on the walk discovered was a species that was new to me. On a scaffold board used for steps, a small blue polypore (example photo above) was peeking out. Having seen it elsewhere on social media in the last week, I can confirm it was blueing bracket. I’m back there soon so will aim to get some *actual* pictures next time.
This autumn it will be 9 years since I first began photographing fungi. I want to share how I found a passion for these incredible organisms and show the first photos I ever took of fungi.
I owe thanks to several people for tuning me into the world of mushrooms. David Warwick, who led fungi walks for volunteers and the public for London Wildlife Trust at Sydenham Hill Wood, shared his knowledge with his fellow volunteers and helped me to gain an interest. That was where I learned about fungi and, over 7 years, had the opportunity to watch them pop up and fade away across the nature reserve.
Turkeytail
The biggest thanks of all go to Ashley White who was the Project Officer who managed the Wood when I was a volunteer. For anyone who has ever volunteered, you will know that the person who leads you is as important as the thing you’re volunteering to do. Ashley inspired many of us to follow our interests in many areas of conservation and ecology.
Velvet shank
My first real attempts to photograph fungi took place in November 2011 during a volunteer day. I used a Nikon D60, a 10 megapixel camera (the equivalent today is double that) that I was given as a birthday present in 2008. I had no editing software and the photos here are as they were taken in the camera, which you can probably appreciate.
Sulphur tuft
One of the more memorable images that I contributed to London Wildlife Trust was this happy bunch of sulphur tuft. This species is probably one of the most common in the UK. It’s toxic but charming to look at. I respect its ability to show up in the street and in all manner of other locations.

Photography has always been a way for me to learn about much more than cameras. To identify the majority of species of fungi, you’ll need to undertake all manner of experiments that I am way too lazy/skilled enough for. I want to spend as much time outside in the company of the things I enjoy photographing. Too much time is already spent indoors. All these are excuses, I know.
Parachute
I think one of the most interesting things about fungi are their diversity. This doesn’t just mean there are a lot of species (over 120,000 accounted for on Earth, probably more than 1,000,000 in reality). It also means they appear in all kinds of places: leaf litter, holes in trees, the ground, the pavement, sometimes even inside your house. That’s not really what you want.
Brittlestems out of focus
After autumn volunteer days I would seek out fungi anywhere I could find them. I had begun to notice some growing down in the leaf litter. As you can see from the photo above, it’s difficult to take photos on the ground without a reticulating screen. Mine was fixed which led to classic images such as the above. These are brittlestems. Over the years at the Wood I would notice this family of mushrooms popping up in damp patches under leaf litter.
Fairy inkcap
Many of the mushrooms in an urban woodland like Sydenham Hill Wood are common species that can pop up after a decent amount of rain. These fairy inkcaps are often found at the base of steps. The steps in the Wood were constructed by volunteers using wooden sleepers, planks for the edges and then filled with gravel. These mushrooms like steps so much I have even found them growing in Clapham Junction station on steps! For those who don’t know, this was once one of the busiest railway stations in the world. Thousands of people rush up and down these stairs every day.
What’s not to love?
For all the negativity around nature conservation in Britain – and for me all contact with nature in the UK fosters a relationship with conservation – fungi gave me a sense of nature’s attitude of I will show up where I want, when I want. For anyone who has ever felt constricted by the physical environment we are forced to live in, nature is always looking to re-align it. As with fungi, it just takes time.

Fungi says to me (not literally) that life does not stand still. Fungi are a part of life processes which have no end. Fungi are always building and feeding a new world whether we like it or not. Perhaps that’s what seeing those fairy inkcaps on the steps of Clapham Junction station taught me. We may be extinguishing a beautiful diversity of life on Earth, first with large, charismatic animals. But nature is complex, unknowable in its entirety, and it will never stop.
For seven years I volunteered and worked for London Wildlife Trust at Sydenham Hill Wood and Dulwich Wood in south-east London. These woods are the largest remaining remnant of what is known as the Great North Wood. During that time I soaked up a lot of information, conducting my own research into the cultural and natural history of the area. I led guided walks and gave public talks on as many areas as possible related to the natural and cultural history of the area. I have condensed much of that information into this blog post. An earlier version of this post was handed out to attendees to walks and talks on behalf of London Wildlife Trust. My knowledge of the entire Great North Wood, which Sydenham Hill and Dulwich woods are the largest remnant of, is not strong enough to ‘write a book on’, but I have posted about the history of One Tree Hill, another remnant, before. This is my whirlwind around these precious woods from the time of glaciers to present day.
Wildwood: 12,000 BC
The Dulwich woods are a collection of remnant ancient woodlands in south-east London, made up ofSydenham Hill Wood (a nature reserve managed by London Wildlife Trust), Dulwich Wood, Low Cross Wood, Hitherwood and Dulwich Upper Wood. The woods are generally known as Dulwich Woods or Sydenham Woods by local people, sometimes influenced by whether they are from the Sydenham side of the ridge in Lewisham or the Dulwich side in Southwark.
Parts of the Sydenham Hill and Dulwich woods are thought to have been covered by woodland since the first trees returned to Britain at the end last glacial period, some 14,000 years ago. The end of the UK glaciers came when climate change led to a period of warming. This warming melted the great ice sheets that had spread across the Northern Hemisphere and sat north of London. As the ice melted, the ensuing water created lakes, rivers and wetlands and the rocky debris carried by the retreating ice carved open valleys and new landscapes. While what is now the British Isles remained connected to continental Europe, the Thames was a tributary of the Rhine in Germany. Today, off Sydenham Hill runs the Ambrook stream, a tributary of the Effra, a ‘lost river’ which still enters the Thames at Vauxhall.
Trees spread by seed on the wind or with the assistance of jays (‘scatter-hoarding’), red squirrels and small mammals. This ‘wildwood’ provided habitat for returning wolf, bear, lynx, elk, beaver, otter and deer, along with birds, mushrooms, insects and wildflowers. Hunter gatherers followed their prey into this more hospitable landscape and made settlements in the woods by clearing trees and creating more open areas to live in.
By 6,500 BC the ice had melted to such an extent across Europe that sea levels rose and flooded the low-lying plain between Britain and Europe, creating the British Isles as islands physically separate from Europe. By the Neolithic period (4,000 BC) the wildwood had been much reduced and people exploited nature’s resources like never before. The growth of farming, developed in the Middle East and spreading through Europe, meant that populations were increasing and the hunter gatherer’s way of life was disappearing.

The Great North Wood: 500-1500 AD
The Dulwich woods are the largest remaining part of the Great North Wood, the early name given to what was left of the wildwood in south London by the Anglo-Saxon period (AD 410-1066). These remnant ancient woods straddled the clay ridge running from Honor Oak to Beulah Hill. The Romans had come and gone (AD 43-410), forging new roads and making use of the Great North Wood’s resources of oak, hornbeam and hazel, mining its clay for brick and pottery. It was the ‘north’ wood because it was north of Croydon, a thriving medieval market town. The Anglo-Saxons also wanted to differentiate between the Great North Wood and the Weald, another extensive woodland landscape that sits between the North and South Downs, running as far as Hampshire in the west and Kent in the east.
It was only later that placenames related to the woods began to appear: Selhurst and Brockley being two good examples. The use of ‘hurst’ at the end of a name indicates a wooded hill, possibly a place where timber was removed or used to some specific purpose, whilst ‘ley’ means a clearing or settlement in woodland. ‘Brock’ is the old English word for badger, an animal which still clings on today in secrecy. Names like Forest Hill are deemed artificial, though it likely refers to the wooded ridge of Sydenham Hill. The Great North Wood was no forest at all, unlike the New Forest, Ashdown Forest or Epping Forest, it was not created for the purpose of a royal hunting ground. ‘Norwood’ is arguably the single truest reflection of this ancient landscape. Penge is London’s only Celtic placename, meaning ‘the end of the woods’.

Woodland industry
The Dulwich woods have been patrolled or cared for by a warden since as early as the 1200s. One of the key industries was tanning, where the oak bark was peeled off and taken to the tanneries and soaked in with hides to make leather. From the 1600s to the mid-1800s it was the second largest industry in England. The tannery at Bermondsey was the destination for much of the woodland produce. Oak trees were harvested after some 80-150 years to build ships, therefore allowing the British military to ‘rule the waves’ and put the ‘Great’ in Great Britain, as some people say. Britain’s oaks ships were the upper hand in battles waged at sea against the Spanish, the Dutch and attacks against the Chinese mainland.
Britain’s isolation as an island protected it from land invasion after the Norman Conquest of 1066 and the end of Anglo-Saxon rule. The harsh strictures of Forest Lawand later royal protections for woodland meant that up until the Napoleonic Wars, the oak resources in England enjoyed some stability. To make one oak ship today would likely require the entire felling of Sydenham Hill Wood and Dulwich Wood combined, some 25 hectares of woodland. Needless to say there is no appetite for such. We should also remember that the Dulwich woods were never ‘forest’ in the Norman term, despite what the word means today.
Colliers were charcoal burners who lived in the woods, an industry of huge importance to London and local villages. Trees like hornbeam were coppiced or cut down to their stump to form multi-stemmed trees that could be harvested for wood indefinitely. The wood was stacked into a kiln, in this case made from clay, and burned to create charcoal. Other woodland products included poles, posts, bavins (bundles of twigs for firewood known also as faggots), birch twigs for brushes and withies (long, thin hazel shoots).

The Norwood Gypsies and other local characters
One of the more interesting local placenames is Gypsy Hill, in reference to a camp of ‘gypsies’ who were famed for their presence there. Margaret Finch was known as ‘queen of the gypsies’ and was visited by the Victorian middle classes to have their fortune told. It is said she was so ‘decrepit’ she could only ever crouch. Other notable dwellers within the woods included Samuel Matthews, the hermit who lived in a cave dug near where the Cox’s Walk footbridge is. He was murdered in 1802 for his wealth collected as a jobbing gardener in nearby properties. He was said to be a popular local figure but his murderer was never convicted.

Local literary figures include William Blake, whose vision of angels took place on Peckham Common, possibly after a visit to the Dulwich woods in the 1760s (and maybe the ingestion of some magic mushrooms?). At the bottom of Cox’s Walk the poet Lord Byron studied at Dr. Glennie’s above what was then the Grove Tavern pub in 1799. John Ruskin walked in the woods during the time of the Crystal Palace, lamenting the place of the building on the wooded ridge.

Enclosure: 1720-1830s
In the 1700s Acts of Parliament were put in place to remove common lands from public ownership and allow their sale and enclosure. Locally affected commons included Westwood or Sydenham Common which covered much of what is now Forest Hill, Dulwich Common which is best represented by the Dulwich and Sydenham Hill golf course, Dulwich College playing fields and Dulwich Park, and Penge Common which was enclosed as Penge Place and is now Crystal Palace Park. Sydenham Hill Wood did not exist at this time but was a series of coppices spread across the Dulwich woods in the form of Peckarmans Coppice, Ambrook Hill Wood, Lapsewood, Kingswood and Vicars Oak Coppice.
This seismic political shift has created the townscape and suburbs we see today in London. It is only through hard-fought planning battles, philanthropic foresight and good fortune that any of London’s commons still exist. The enclosures put in place the eventual development of the coppices known today as Sydenham Hill Wood. By the 1730s Cox’s Walk had been cut through an area known as Fifty Acre Wood from Sydenham Hill in order to attract visitors from the Sydenham Wells to the Green Man Tavern at the junction of Lordship Lane and Dulwich Common, site of the Dulwich Wells where natural springs rose. By the early 1800s Fifty Acre Wood had been grubbed out for farming, now forming part of the Dulwich and Sydenham Hill golf course and the Marlborough Cricket Club fields.

The Victorians: 1800-1900
Immense change came to Sydenham Hill and Dulwich with the construction of the Crystal Palace in 1854. In 1865 the Crystal Palace High Level railway was cut through the Sydenham Hill coppices. It took millions of people to the Crystal Palace’s Great Exhibition until its eventual closure in 1954, after the Palace had burned down in 1936. The Cox’s Walk footbridge was constructed over the railway line to allow the continued use of the pathway. The Crescent Wood tunnel, which plugs the southern end of Sydenham Hill Wood, was closed to the public in the 1990s due to Health & Safety concerns and later it was designated as a registered bat hibernation roost due to the presence of brown long-eared and pipistrelle bats using the crevices in the old brickwork.
In the early 1860s the construction of large villas along the Great North Wood ridge running from Forest Hill to Beulah Hill began. The coppices of Sydenham Hill Wood were separated into smaller plots of land and sold on 99-year leases by the Dulwich Estate. The residents of these houses were wealthy, with some houses accommodating more than 20 people, in this case servants for the families. Lapsewood House was home to Charles Barry Junior, the designer of newer Dulwich College, North Dulwich Station and St. Peter’s Church next to Cox’s Walk. Another house, Beechgrove, was lived in by Lionel Logue in the 1930s and ‘40s, the speech therapist characterised in The King’s Speech. A garden folly was constructed with Pulhamite, a material patented by James Pulham, in the grounds of Fairwood. The cedar of Lebanon which still remains was in the grounds of the Sydenham Hoo and can be seen as a sapling in Victorian illustrations of the garden.

The returning wild: 1950-present day
The advent of the First and Second World wars brought irreversible change. Traditional woodland management was extinct and the Victorian boom was over. Many of the houses were nearing the close of their leases in the 1950s and by 1980 all of them had been demolished. Local people had been entering the grounds of the old houses and the disused railway line since the 1950s. The landscape was returning to woodland as trees began to retake the gardens and railway cutting with no intervention taking place from either the Dulwich Estate or Southwark Council. In 1981 London Wildlife Trust were formed and by 1982 Sydenham Hill Wood had been designated as a nature reserve. This was after fraught and long lasting battles involving Southwark Council, the Dulwich Estate and local people spear-headed by London Wildlife Trust, the Dulwich and Sydenham Societies and the Horniman. London Wildlife Trust are now lease holder of Sydenham Hill Wood and each of the former mansion grounds running along Sydenham Hill. Today the Trust, Southwark Council and the Dulwich Estate are working in harmony to protect the natural heritage of the Sydenham Hill and Dulwich woods with the support of volunteers.
The woods are experiencing historically high numbers of visitors, with data suggesting that over 100,000 people step through each year. It is a critical time for people to access and understand our green spaces due to the dislocation many feel from nature and the impending threats of climate change and species loss. Sydenham Hill Wood is one of the most important green spaces in London for the story it can tell about human impacts on the land, challenging our concepts of what is natural and normal. Its 10ha has seen it all, surviving through all that our species has thrown at it in over 10,000 years of human history. It bears those scars but its wildness remains. Who knows what it will see in the next 100 years.
Last year I was commissioned to write this piece about the four seasons in Sydenham Hill Wood. Woodlands are beautiful, yes, but the lives of their inhabitants are not as gentle or pleasant as we might like to think. Here are my four dispatches.
Spring
Along the trackbed of the disused railway wild garlic grows. It’s a remnant of the wood’s ancient lineage, its deep green is welcome refreshment on a grey spring afternoon such as this. Every so often you find other indicators of the wood’s age. Wood anemone are growing in isolated clumps and English bluebells, too, some hybridising with the Spanish garden variety. The hornbeam standing along the track is another pointer to the old age of Sydenham Hill Wood.
Above our heads is another species sure to have been breeding here for some time. There are three tawny owl chicks sitting in the top of a large ash tree not yet in leaf, and through the bare branches we have a clear view of them. They snuggle into their plump, downy coat of feathers, calling to their parents, with rasping voices you might not expect them to make.
The wood’s bird community is watching, not least because the tawny owls are the top predator in the wood and one of the chicks’ parents is nearby trying to make a kill. Last week we found a crow’s head by the pond and it now appears likely that the adult tawny that spawned the trio above is the culprit. The birds know it too: there is an anxious din of woodland birds – woodpecker, crow, robin, great tit, blue tit, ring-necked parakeet, nuthatch – as the rufous adult tawny emerges from its hiding place.
The chicks are further along than expected, they move one at a time over our heads and closer to mum or dad, their spread of primary wing feathers giving them a tactile appearance, each like a finger. The parakeets are the most successful in bothering the young owls as they shriek and dive around them, the vibrancy of these exotically coloured birds muted by the task, on a dour afternoon in the spring wood.
Summer
The leaves of trees under torchlight are sticky with honeydew, a little like our faces, damp with sweat and bothered by mosquitoes. I swat them away. The wood is perspiring, wet with aphids. The air is thick with the funk of wild garlic that has flowered and gone. Stars are appearing in the ocean of night sky. A dot of light moves across the expanse. Is it a satellite?
A male tawny owl calls from acres away. We blow through a hazel whistle carved in a fashion to mimic the owl, and the bird itself responds in kind, edging closer and closer to us after each play of the whistle, its voice becoming clearer: What’s the time Mr. Owl? Now there is no foliage between us and anxiety stirs. We decide it’s better to stop in case the tawny thinks we’re another male. They are renowned for their aggression in protecting territory.
With the wood under the spell of darkness, the industrial world is reduced to a dreamy wash. Beyond the lining of trees could be an endless wildwood or an open pasture – the imagination runs free in the absence of engines and electric light. Some centuries ago the old woodland was felled and turned into farmland that skylarks, corn bunting, lapwing, turtle dove and cuckoo would have colonised. These birds are now absent from land that is used for cricket, golf and rugby.
From the glade’s sleeping bed of rosebay willowherb the great ghost of a hawkmoth ascends. I swoop the child’s pond-dipping net I am holding towards the monstrous insect, bringing the net and my knees to the ground. I carefully peel it away from the grass, revealing only shadows. The mysteries of the night wood remain.
Autumn
We’re sitting around the moth trap again tonight. A large flock of crows are returning to a roost in the direction of Dulwich Park. There’s something about vast movements of crows, it gives the sense of an ending. In old times this would have been the signal to down tools at the close of a day labouring, ‘when the crow flies’, as they used to say.
The insect numbers have visibly dropped since summer but the pipistrelle bat hunting just above our heads shows there must be enough for them to eat. The twilight is metallic blue, stars are lanterns in the sky untouched by trees.
We’re surrounded by oak woodland, with smatterings of birch, ash, willow and hornbeam. We can only hope the darkening wood conjures something beautiful for us to behold. The leaves around us are soon to fall and even in this fading light you can sense the change, nature exhausted after the sex of spring and summer’s heat. A hobby flies the same path as the bat, catching a moth in midair.
Night falls. Nocturnal mammals begin their movement through the leaf litter, their sound much bigger than they actually are. A moth has been drawn to the bulb of our moth trap and we retrieve it in a clear plastic pot. It’s medium-sized, purple and mustard in colour. It’s the barred-sallow. This moth has evolved to match the leaves of autumn, but it’s early, many of the trees are still verdant green. We release the insect and it disappears into the dark.
Winter
A slender pathway cuts through the ground layer of ivy, most likely to have been forged by a train of foxes. A large ash has been pulled down by the wind, the underside of the ivy leaves wrapped around it are a fresh colour, like the flesh of a lime fruit. To the side a den has been made with string tied to the rotting logs that rest against a tree in a tepee form. Sometimes people spend a night in the wood and so the sign of a tent or den surrounded by food packaging and drinks bottles is not unusual. There isn’t much litter to be found tonight, other than things the ivy has subsumed, bottles or cans taken in by the soil or blown over from the road. Spiders make a home for themselves in empty bottles and the woodlouse is a common inhabitant of an old shoe. Now the leaves of premature bluebells peek through the earth and we take care not to trample.
We come upon a clearing around a large yew tree, the soil cleared of ivy and plant life by the acidity and shading of the tree’s needles. The trunk is rippled and worn like an old doll’s limb. It’s one of a line of yews that would have been a hedge in the grand Victorian garden that was once here. The villas were built in the 1800s, but too grandiose to last, they were abandoned during the Second World War and, deemed unsafe, were eventually bulldozed into the earth. The ground dips to reveal the whitish bricks of a wall and a trail of broken glass. Behind us is a group of silver birch trees, quarantined amidst layers of ivy and the yew. These birch look like they’re waiting for something.
The other side of the wall shows a support structure for the terrace of the old Victorian villa, where the slow life of the woodland has been allowed to resume. A blackbird calls in the canopy and a great tit sings its winter song down in the woodland glade. The sun is setting low through the slope of trees. It’s time to go home.
