Rewilding Cringleford

Cringleford is a Norfolk village lying about two and a half miles distant from the city centre of Norwich. It is an affluent suburb close to the university and hospital, and lies sandwiched between the Yare valley and the city’s southern bypass. Its remaining arable fields are ripe for development. 

About a decade ago the slow process of converting farmland into premium housing estates began. Access roads were inserted and three-bed houses built in streets with names like Dragonfly Lane, Chervil Close and Nightingale Drive. Everyone wants a bigger house with a double garage, and everyone also wants green space and access to nature.

Round House Way serves these estates and either side of it lies an area of green space. An aerial photograph on Google Maps shows a mosaic of bushes and grassland grown on land tumbled down from arable.

This ‘self-willed’ habitat has taken twenty years to develop its intricacy on what is essentially a housing company land-bank. But time has been called on this natural growth. This year the western side was swiped and shredded to ground level, in preparation for redevelopment [photo 1].

The eastern half remains. People might say “it’s derelict, it looks a mess - it’s a wasteland”. 

But what we find east of Round House Way is scrub land with a richly biodiverse fauna and flora – fruit of two decades of chance, natural elaboration. [photos 2 & 3]  An architecture of hawthorn, blackthorn, oak, rose, willow and bramble frames a herb-rich sward bumpy with anthills and the myriad craters of ground-nesting bees. A solitary cat ranges out from nearby houses, captivated by vole and shrew. Goldfinches flit among seed heads of teasel. Foxgloves and St John’s Wort star the grass. Toadstools shoulder up through the remnants of last-year’s matted vegetation. Processes of seed-time and decay are running their natural programmes at ground level; the loamy soil is bouncing back from the decades of agricultural treatment received from insecticides, herbicides and fungicides. Autumn is displaying a complex of yellows, browns, reds, russets and greens – falling leaf debris making the foundations for a future nutrient hoard. This land is owned by a housing company.

The planet is in a Biodiversity Crisis. How can we turn local development into an engine for restoring biodiversity? It requires political will at national and local level, and buy-in from the building companies. If an environmental impact assessment has been carried out at Round House Way it will have assessed impact on a set of prescribed species, but ignored the cumulative value of allowing a self-willed ecological community to develop true biodiversity over a twenty-year span.  A real natural asset has grown up and could be incorporated into local Green Infrastructure if the political will – and awareness – were there.

But soon the flail mowers will move in soon and all this biological richness will be obliterated. A new ground-zero will be set – but a greatly impoverished one.

I am not really asking for protection of the site – arguably any patch of land on this soil type in Cringleford could develop such biodiversity over a twenty-year time-span. I am asking for the biodiversity of such scrub lands routinely to be recorded and then evaluated in terms of their actual - and potential – assemblage value as ecological hotspots and corridors, and for this information to be translated into the planning process. I want all of this site’s biodiversity to receive greater consideration than the usual ecological consultants’ reports. This would require evaluation of the diversity of plants and invertebrates and not just vertebrates (Morris & Welch, 2023). The very early stages of abandonment of arable land can be highly productive for invertebrates (Fuller & Freeman, 2025). 

We know that scrub habitat is ecologically valuable. See, for example, a recent JNCC report which was written to inform government decision making (Mortimer et al, 2000). Scrub does pose challenges for practical management due to its successional nature, but its biodiversity value is absolutely clear. If there is a will to manage it properly it can revitalise the natural assets of urban and peri-urban areas such as Cringleford. It could be part of the invaluable reservoir of biodiversity which ensures the resilience of our nature networks in the face of climate change as well as the increasing pressure of human settlement. Scrub should be understood as contributing vital Green Infrastructure to development projects – provided it can be recognised and properly valued in terms other than financial ones. Round House Way East is a parish asset.

For example, a play area for children; a foraging terrain for birds; a place to go blackberrying and collecting sloes; a cherished wilderness; airspace for bats to hunt moths; a resource for dog-walkers and bird-watchers; a secure place to dig a nest burrow. [photo 4] Round House Way East is a former arable field which is busy rewilding. Can we support that process for future generations of humans, plants and animals?

Carstone and Chalk

'Carstone I will mention in order to abuse it" 

(Jacquetta Hawkes ('A Land', 1951).


Why not? This orangey-coloured Norfolk sandstone does not look attractive on its own nor does it combine attractively with other materials. It presents a burning, gingery face to the world and does not weather gracefully. It outcrops between Hunstanton and the Nar valley, where several quarries - such as Snettisham and Middleton - specialise in producing blocks of 'big carr' for masonry or 'small carr' for hardcore or shillet walling.  


The Carstone is at its finest and boldest in the famous geological layer-cake of Hunstanton Cliffs. It underlies the Red Chalk and Grey Chalk and forms a sort of solid biscuit base for those more mellow, pastel layers. Its only fossils are worm burrow traces, and it is laced with liesegang rings: patterns of dark and light cementation brought about by migrating iron compounds. Here, it looks like a sort of industrial slag. 



The only way the Carstone can achieve aesthetic lift-off is probably as a crude pigment. It is so gritty that its iron oxide is a chore to extract for creating home-made paint, but its bold, uncompromising colouration lends itself to astonishing, disharmonious juxtapositions in the landscape. At outcrop it colours the soil a rusty brown and on Hunstanton beach it yields a brown, exotic-looking sand. Hawkes called its effects 'strident': sometimes stridency is needed to shock us out of our visual complacency. Consider this photograph taken in the Snettisham Carstone Quarry.

Grey Chalk is as different from the Carstone as cheese. It is indeed it looks like a type of moon-cheese, with a glimmering and dulcet milkiness which is readily ground into lime and - in the right circumstances - can be cut into blocks of stone known as clunch. The Grey Chalk and overlying White (Upper) Chalk span over 40 million years of time. They were deposited on the seabed in a world which was much hotter than our own and had a much higher percentage of atmospheric carbon dioxide. Hawkes calls the Chalk the 'prime creation of later Cretaceous times'. Indeed, the carbon dioxide went into the skeletons of countless billions of planktonic marine organisms whose lime-rich remains rained down through the water and were laid down as calcium carbonate mud. The Chalk now forms ancient seabed deposits as far afield as Russia and Kansas as well as the White Cliffs of Dover.

Unlike the White Chalk, the Grey Chalk does not contain flints. Instead, it has a variety of body fossils such as echinoids and bivalves and is composed of various horizons of harder or softer texture. It has been extracted in a series of quarries along its outcrop, as at Gayton and Hillington. Where they intercept the groundwater, flash ponds may result on the quarry floor and surprise the eye with a tropical turquoise-blue.

Clinging On

As the human world reels under the malign influence of Coronavirus, my thoughts turn to Cretaceous barnacles. 

This sudden interest in extinct cirripedia is prompted by a paper published a month ago by Professor Andy GaleNew thoracican cirripedes (Crustacea) from the Cretaceous of Europe and North Africa.[1] It announces the discovery of new extinct genera and species of barnacle. There are two sorts: the acorn/wart-type (sessile) barnacles familiar from rocky shores and the stalk-type (pedunculate) 'goose barnacles' sometimes found attached to drift wood. 


I have never really thought about these crustacea before. They are easily overlooked - that is until you gash your hands or feet on them at the seaside, or eat them in a Portuguese restaurant. What crystallises my interest in them now is that one of the Zeugmatolepadid family now bears my name: Subsecolepas holtwilsoni. It is a lepadid barnacle - one of the stalked type. My thanks go to Andy for the honour. I think i
ts taxonomic status is:
Phylum - Arthropoda
Clade - Mandibulata
Clade - Pancrustacea
Subphylum - Crustacea
Class - Maxillopoda
Infraclass - Cirripedia
Superorder - Thoracica
Order - Pedunculata
Suborder - Scalpelliformes
Clade - Thoracicalcarea
Family - Zeugmatolepadidae
Subfamily - Martillepadinae
Genus - Subsecolepas
Species - holtwilsoni 
Andy Gale is one of a very small band of palaeontological researchers active in the field of fossil cirripedes. Their most illustrious forebear is Charles Darwin. Thomas Withers was active from 1910 to the 1960s, and catalogued the fossils specimens at the Natural History Museum, London. " There can be no doubt the Wither's 'Catalogues' are to fossil lepadomorph and verrucomorph barnacles what Darwin's 'Monographs' are to Recent barnacles."[2] Andy has been one of the most prolific cirripede researchers in recent decades, focusing on the Cretaceous Chalk and publishing many papers. He says that S.holtwilsoni is common in chalk of the Upper Campanian stage in the UK, and that 400 fossil specimens have been found at various old pits in the Norwich area. He named it after me for helping him dig in these pits and for having been involved in their conservation, including Keswick, Catton, Cringleford and Whitlingham.

Collecting samples at Keswick, 2015


I have not visited any chalk pits lately. Britain today is in emergency 'lock-down', and I feel sorry for city-dwellers cooped up in flats and terraced houses. At least I have an extensive wildlife garden to ramble in, and I also enjoy exploring the meaning of our geological heritage.

Crustaceans of the Campanian seas are a great imaginative diversion - a dépaysement, as the French say. Geology and palaeontology call us out of our own time and down into the profound depths of planetary and biological evolution. I try to imagine the lifeworld of the extinct species that now bears my name.  


Here are photos of the type specimens of S.holtwilsoni, variously sourced from chalk pits at Keswick and Cringleford, and all are now archived in the Natural History Museum. They show elements of the set of hard, calcareous plates which enclose the head of the barnacle.

Stalked barnacles from JG Wood: 'The Illustrated Natural History'; Routledge, London, 1863

Darwin's drawing of a Middle Jurassic stalked barnacle Pollicipes concinnus,
as found attached to the shell of an ammonite.[3]


Contemporary stalked barnacles attach themselves to floating objects, particularly driftwood, turtles and ships. According to Andy Gale, S.holtwilsoni and other Zeugmatolepadids probably had a similar lifestyle, attaching to the shells of free-swimming ammonites and seabed-dwelling inoceramid bivalves as well as floating wood.[1, p.245] There must have been a steady rain of their plates falling into the carbonate-rich mud of the sea floor, perhaps 100 to 500 metres down.[4] 

The Campanian stage spans from 83.6 to 72.2 million years ago.[5], and chalk of this age is well-represented in Norfolk and Suffolk. I have visited many quarries of this period in the Gipping valley and Norwich areas. At Keswick and Cringleford I helped clear the chalk exposures so that Andy Gale could record the geological succession and take samples. The samples are treated with glauber's salt and freezing in a repeat process until the miniscule fossil fragments - echinoid spines, bits of coral, fish scale, shell, etc - are freed from their chalky matrix and can be examined under a microscope.

The contrast between the physical reality of an old chalk pit, with its crumbly, scrub-infested chaos, and the clarified world of knowledge compiled by over 150 years of scientific research into the Chalk is remarkable. We now know much about the Earth's geography during the Campanian, for example that Europe was an archipelago of islands.[6] We know much about biodiversity and details of climate and chemistry.[7; 8]

All this is wonderful, radical stuff to explore during COVID-19 lock-down. Like astronomy, geology has the power to frame human life against an almost infinite scale of time and space. Like pedunculate cirripedes, we cling for a few seasons to our floating attachment points and then - like them - our debris will inevitably find its way to the metaphorical sea floor. Perhaps only our names, inscriptions and genetic coding will survive us, for a century or two at most. The history of taxonomic revision makes clear that not even species names backed up with diligent taxonomic description may be proof against time.

Norfolk Island Pine

There's a Norfolk Island Pine (Araucaria heterophylla) sapling on the 6th floor at County Hall, Norwich. 

It is not looking particularly happy, but I'm told it is a lot happier here than in its previous location downstairs in the foyer. A gift to the County Council from a well-wisher, it was given a home by the Environment team last year when a decision was taken to remove all potted plants from the foyer.



I am delighted to make the plant's acquaintance. It is a member of the Araucariaceae, a family of primitive conifers with their evolutionary roots over 200 million years ago, in the late Triassic period. The Araucariaceae once thrived around the globe, including Europe, but since the great extinction event at the end of the Cretaceous, about 65 million years ago, they are only native to the southern hemisphere. Members include the monkey puzzle tree (Araucaria araucana) which makes spectacular forests in Chile, the towering New Zealand kauri (Agathis australis) which produces kauri gum, and the extraordinary Wollemia nobilis, a living fossil discovered in a remote Australian ravine in 1994. They are thought to have diverged from a common ancestor in the early Cretaceous period.[1]

The plant has an upright stem covered with pointed, scale-like leaves towards the top and bristling branches that emerge radially. It has an aromatic, resinous smell. I can imagine a small Composognathid dinosaur hiding behind it.


I'd like to have a specimen of A.heterophylla. It is not hardy in the British climate, so it would have to be kept in a plant pot then brought indoors in autumn. However, it is said to be fast growing and can reach a height of over 50 metres. I may have to think twice about the idea!![2]

Flat field - Ancient oak

22-4-2017

The parish of Bressingham (south Norfolk) is hardly a hilly place, but it does have 'upland' and 'lowland' areas. Its uplands are the gently rolling till plateau north of the A1066 turnpike; its lowlands are the flatlands of the Waveney valley lying south of the road. The one given over to clayland arable farming; the other to pasture and woodland on relict valley fenland.

Prof Tom Williamson (University of East Anglia) gave a walking talk today on the parish's cultural landscape history. The event was hosted by the fledgling Bressingham History Group, courtesy Linda Holly, and was enjoyable and well attended. I contributed a geological dimension to the discussions.

Apart from the congenial company, two features of the walk were outstanding.

Firstly, the view south from Fen Street. A long, narrow field - flat as a runway - leading the eye south towards woods known as Horse Fen and the hidden River Waveney. It looks a suitable pasture for sheep. The BGS map tell us this field is underlain by peat. If so, what we see today are the dried-out and shrinking remnants of the thick mattress of decayed swamp woodland and fen vegetation which has covered this land for most of the last 10,000 years. Our ancestors cut turf here and went wildfowling. According to Faden's map of 1797 it used to be part of Bressingham Fen. Today, drainage has reclaimed much of the the land for farming, and it is a remarkably flat expanse of pasture. It owes its long, thin shape to the historic pattern of 18th and 19th century enclosures in the Fen. This can be seen in the early 19th century tithe map. Four of the old fields have now been knocked into one.

Secondly, the view of an immense, ancient oak tree in a clayland meadow at Valley Farm.


The tree has a stalwart trunk and colossal boughs, and is as stag-headed as the horns of Herne. It must be over 500 years old, as Tom suggested. It is truly an ancient, Mediaeval being, worthy of veneration. I wonder when the crown began to die back. Perhaps the field was ploughed for agriculture in one of the World Wars? Nevertheless, I am impressed that the occupants of Valley Farm have come & gone over the centuries without significantly interfering with this extraordinary tree. I am reminded of the celebrated Winfarthing Oak, sited only a few miles away, once the largest in England, which finally died in the 20th century. What makes people preserve such trees rather than fell them for firewood?

Horse Fen field and the Valley Farm oak - the one smooth and the other craggy - are phenomena of the parish; both are products of human cultivation, and both have stories to tell about Norfolk's landscape history.

Hockham Mere

9-12-16

My friend Julia B and I met yesterday at Great Hockham for a wilderness expedition.

Julia is researching a book on Doggerland, the inhabitable land area in the North Sea basin which was drowned as sea levels rose at the end of the last glacial period, the Devensian. Its landscape changed from tundra to forest, then marsh and finally sea, in a process that spanned the transition from the Devensian into our own Flandrian warm period, roughly from 10,000 to 7,000 years ago. This ancestral land is now out of reach of our exploration: we needed somewhere else to experience elements of its vanished wilderness.

Is it possible to talk of 'wilderness' in Norfolk? Other countries have tracts of land we can easily label wilderness - areas defined by the lack of human habitation or disturbance, graced with plant and animal communities and geomorphological processes that operate in ways unshaped by human agency. 'Tis true, we are hardly likely to encounter wolves or frost-shattered peaks in Norfolk - let Ansel Adams picture them for us - but I think the intertidal zone is implicitly wilderness. We have some 90 miles of coastline at the land/sea interface, where the fluxes of wind, waves and tides shape the sand and shingle without reference to humans, and plant and animal lifeworlds may create their biological meshes of meaning undisturbed.

Wind, sand and razor shells on Titchwell beach.

We also have wilderness at the micro-level: life with its processes, unmediated and raw, at the levels of cell and leaf, in every wood, field or garden, under every stone, in every lump of rotting wood. There are beings for whom this spatial level is their life's horizon, and I imagine it is pure wilderness down among the grass roots in my lawn - the selfsame lawn I walk or picnic on. Wilderness is the landscape that belongs to the Germanic vill or wild, the Latinate desierto, selvaggio or sauvage. The word enfolds, in English, a sense of the alien, empty and untamed. At its heart is wildness.


We carry wildness in ourselves, for instance in our blood flow, breathing, dreams and borborygmus which have their own strange, untameable life-logic, even though we know them to be truly and organically ourselves. There is also wildness we experience in others when we realise that they are simply 'not me'; they have their own life-logic which may overlap with our own but it is radically Other and different, perhaps alien. It could be a friend, a neighbour or a bird. We find they are partly 'me' - but mostly not.

Thus, our perception of wilderness may have its roots in the radical Otherness of a landscape: we are forced to meet it on its own terms and not ours. We may be able to find resources and affordances within it, places of identity, attachment and utility, but it remains - at its core - essentially 'other' and wild.

Our expedition had prehistoric wilderness in mind - specifically any evocative traces of the lost life-world of Doggerland to be found in the Hockham area. Its task would be both dreamwork and a perceptive attention to the present landscape through which an imaginative experience of the late glacial and early post-glacial landscape might become possible. The result would be writing.
'A text of nature writing is a representational model of the meaning relations that a writer has perceived in the environment under specific conditions, determined by the time, location, and the biological and cultural abilities of the perceiver.' [1]

As a 'representational model', nature writing is a translation from the Otherness of nature, as we experience it, into the selfhood of words. We go outward into Otherness: we return to Ourselves. In the case of Doggerland we are dealing with a world of plants, animals and human life which can no longer be directly experienced. Translation may risk going awry and descending into ungrounded phantasmagoria that have the ring of fantasy but not of vital truth. What we need is eye-opening places where what is experienceable today and what was experienceable 10,000 years ago can come together and bear fruit: the fungi and berries of lifeworld visions.

Suppose we wanted to experience a Devensian environment today we'd need to go north, to the Arctic. The last ice age lingers there, clinging to the circumpolar zone in the face of the planet's encroaching hyper-warmth, along with its refugees the snow buntings and musk oxen, beetles and midges, pingos and permafrost. My studies tell me this part of Norfolk is awash with physical (and even some biological) evidence for life in the Devensian.

If we wanted to experience an early Flandrian environment we'd need to go north-east, to visit the low-lying landscapes around the Baltic, for example Soomaa in Estonia, where bogs and boreal forest go hand in hand; landscapes of birch and pine, beetle and midge, lake and moraine. The marshy, forested land at Frost's Common and Cranberry Rough, Hockham, has a similar aspect, though no longer inhabited by wolf, elk and lynx.

For Doggerland itself, scientific research has begun to lay bare the geography using remote sensing and sampling techniques[2].We are beginning to chart the layout of drowned estuaries and low hills, fens and plains, on the seafloor and beneath it. We know about the kinds of plants and animals present, and the timing of the submergence. We now have details of this lost, low-lying landscape available to us in words and maps. It probably looked rather like parts of Norfolk.

For understanding the people of Doggerland, we could draw on the experience of the hunting & gathering peoples of the northern forests, coasts and tundras. They are the ones who grappled in deed and myth, in actions, words and songs, with the realities of life in this kind of environment. This would complement the traces of local Mesolithic occupation. Perhaps some of the people settled at Hockham were refugees from Doggerland. What language, stories and skills did they bring with them?

Hockham Mere

Our expedition was focused on the western side of Hockham parish. It included Frost's Common, an area pockmarked with a concentration of ponds. As a digital terrain map shows, the land slopes hence gently westward into a broad basin area, a shallow sump for water draining from the glacial sands, gravels and clays which underlie it. This is the area called Cranberry Rough, the site of an ancient lake known as Hockham Mere. Its muds were investigated by researchers in the 1940s, who cored down and recovered samples to a depth of 30 ft (9 m). They were able to show that the Mere holds a sedimentary sequence going back to the end of the last ice age, with a fossil pollen sequence to match[3]. 

The Mere
probably existed in some form until Tudor times before being drained with a network of ditches. 19th century maps show this reclaimed land as swamp woodland and rough pasture, with the eastern part set aside as a Poor's Fen allotment; altogether it covered some 190 acres (76 ha). Patches of worked flint near the western end and traces of charcoal in the lake muds are evidence of occupation by Mesolithic hunters & gatherers, more than 7,000 years ago. There is a Roman road, the Peddar's Way, tracking nearby, and the vestiges of a deserted railway line cutting across it. The southern half of the site is managed by the Forestry Commission, and so theoretically it is publicly- accessible. Until recently almost all Cranberry Rough was covered with woodland, but a programme of publicly funded works has now cleared trees and bushes from the southern half of the site, revealing a flat tract of boggy pasture. The oozing, privately-owned core of
its northern half is swamp carr, pristine and impenetrable.

We parked that car near the entrance to Fire Route 83, and entered the forest. We followed our own trackless path.


Frost's Common

'Maa iidse tiigid'
'The land of ancient ponds'

Deadened by crowding trees, the sounds of traffic on the A1075 are muffled and soon die away. Frost's Common has an extraordinary power of dépaysement, of taking one elsewhere - in this case somewhere boreal and strange. I have been in similarly odd, crumbly forests in Sweden where the delightful and the sinister are woven together equally. An attractive variety of broad-leaved and coniferous trees presides over a complex of brooding ponds; the tracks of deer (and some bigger animals) are woven here and there over the earth; in some places dense mats of dead bracken mask a jumble of rotten trunks. Mosses, lichens and fungi abound. Time passes and - pixie-led - one finds oneself going in green circles, for one cluster of ponds looks much like another. One steers by instinct - or the sun, if its position can be discerned.

Reflections

Geologically speaking, the land at Frost's Common is a mosaic of sands and chalky clays, and the ponds are probably relict lithalsa or pingo landforms. Fourteen thousand years ago the ground here would have been swollen with permafrost ice. The surface layers would melt in summer then refreeze in winter. Patches of water-bearing sand in the subsoil would swell up and form large blisters of ice, with freezing and thawing happening on a seasonal basis. At the end of the ice age these active frost mounds became permanent ponds. There must be fifty such ponds and wet depressions surviving at the Common. It is a landscape ravaged by periglacial pox.


'Piirneva niiske luht'
'Bordering a damp meadow'

The hummocky terrain of Frost's Common gives way, on its western side, to an open area surrounded by forest. It is less a glade than a rough, tussocky, damp heath. The ground undulates with a few ground-ice depressions, and is sporadically studded with willow, hawthorn and gorse. It seems to be a tract of clear-felled forest that was not replanted. It is not attractive, but does have a very strong sense of place about it. Many years ago, in the Åland Islands of the Baltic, I waited at dusk for elk (Alces alces) to emerge in such a place as this. Stepping into the open here, one is aware that other eyes may be watching.







'Ja tume männimets'
'And a dark forest of pine trees'

The damp meadow gives way to patchy, mixed woodland of oak, pine, poplar and willow. This in turn gives way to regular pine plantation. Passing through it means treading underfoot a spongey carpet of dead needles; one's horizon is reduced to a brown world of spiky and straight-planted bole corridors; one's hearing is hushed and closeted. Vestiges of freedom still remain in the tree tops, however, where occasional titmice twitter and flit, and breezes may ruffle greenery in the topmost twigs. Our attention is mostly on the ground. We stumble over half-buried snags. We find a startling splash of chrome yellow slime, a creeping myxomycete. We notice the landscape's resources, its tracks, trails and signals. Deer droppings; scraps of egg shell; the tang of a fox; tufts of foxglove or fern. Overhead, away above the tree tops, passing pigeons and carrion crows. The trees are mostly young, perhaps 20 years old, but have none of the casual spontaneity of youth: they are already dry, serious characters. It seems a human body could lie here, in the silence at their feet, buried beneath a steady rain of needles for decades before being discovered. But I suspect my imagination is running away with me here: the foxes would soon make it their own and the crows would strip what remained, leaving just wreckage. The place is more populated than it seems, and there are large, fresh-looking animal tracks meandering among the pines, evidence of other-than-human wills contributing to making the place.


Trackway
The myxomycete

Corridors of forestry brash

We navigate westwards through the forest, until the pines loosen as the ground becomes wetter. Birches and willows step in once more. They mark the eastern margin of the former Mere. We reach a gate from which, 1000 years ago, we might have surveyed wild water and fen.  


Cranberry Rough


'Siin on sissepääs suur raba'
'Then the entry to a large swamp'

We are walking across the old lake ground and its soggy, partly-drained successor. Dark, peat-rich soil has been mechanically stripped of encroaching trees to reveal a wetland in the remaking. Cattle have poached the ground into a black chaos of wet potholes which we step through to reach a balk of higher ground which runs westward across the site. This will be our only access route.




Like hunters, our senses take in the layout of woodland and water bodies, the direction of the wind, the evidence of bird and animal life. At each step we evaluate threats and resources, check our orientation, adjust our thoughts to the terrain and to each other. We find we are not alone.

This marsh is alive with living things that shy in our presence - the birds. They are signs in our wilderness, and we in theirs. Geese, ponderous and clamouring as they rise. Herons, craking. An explosion of teal in a whirr of wings that peels off the marsh, swings round then refocuses farther off, each bird dropping back with a white splash to water. And distant, about 800 yards away, the eye discerns what look like aurochsen - ochreous cattle, hairy and over-horned - pasturing on what the swamp has to offer by way of December's dying herbage. If we want to reach cross the Mere and find the place where the Mesolithic flints were found we shall have to pass them.

Courage fails me. I am unnerved by the aurochsen and the birds. We are standing exposed in a chilly emptiness. Is it wilderness or nature reserve; public or private space? It's only two o'clock but daylight seems already to be fading.

I notice that I have lost or misplaced my mobile 'phone. I want to retrace my steps - our steps - to look for it before the light fails, and Julia agrees. 
We turn back.


The return

'Suur raba,
Piirneb tume männimets,
Siis niiske luht,
Ja maa iidse tiigid'.

'A large swamp,
Bordered by dark pine forest, 
Then a damp meadow
And a land of ancient ponds'.

Walking back, our attention is on the ground, on little details, as we walk; they become the thread back through the labyrinth of our expedition: back across the great swamp - through the forest of pines - across the damp meadow - between the ancient ponds. We revisit our walk's geography in reverse, following my memory's representation (such as it is). I recognise my boot-prints. I remember where I stood to watch a pair of carrion crows. We cross the same beast paths; navigate between the same boles (or just about). I notice a patch of yellow slime. Here is the place among the damp pine needles where we picnicked on green olives, boiled eggs and black chocolate. I recall the crossing of a clearing or the skirting of a pond; the place where we doubled certain bushes, or stepped over a fallen trunk; a pile of droppings or a feather. It is extraordinary how vivid some memories are: I find myself able to retrace tracks and relocate localities we were at two hours earlier. The hunter/gatherer in me is impressed: I am an asset to the tribe.

Back at the car park I find my mobile phone buried safely in a bag, so all is well there. This story poses some awkward questions about the quality of my memory. Perhaps I'm not such an asset after all. However Julia has been discovering the landscape and taking notes about it, and I am pleased to have been her guide.

I have since learned that the yellow myxomycete is Fuligo septica, a species with a strange Fenno-Scandinavian mythology: said to be the vomit of troll cats or, in Estonia, the leavings of the demon Kratt. Each society in each age interprets natural phenomena in its own way. Today, in 2016, the texts books can tell me a lot about the biology of slime moulds, and I find the idea that troll cats may roam the Hockham Woods an appealing one. However, the most important thing seems to me that Julia and I encountered this strange organism together here – out in the heart of a Norfolk wilderness – much as our ancestors, some 9,000 years and perhaps 500 generations ago, might have found it on a pine forest floor in old Doggerland – a landscape now submerged by more than time.

Seal on heita pilku kulla kõnnumaal'.
'There is a glimpse of gold in the wilderness'.

How would our ancestors have named this thing?
