“A list of animals … could become tiresome, but it is necessary to grasp the true richness of nature. Think of it as not so much an inventory as a catalogue leading to compelling and interacting stories…” (Richard Fortey, 2016. The Wood For The Trees. The Long View of Nature from a Small Wood. Collins)
Here is a list of the creatures that have lived in or visited the smallholding in the North-West of Cumbria, where we have lived since 2001. The house and its curtilage date from 1856. We have about 4.5 acres, with sheep pasture (horse pasture until 2001); Victorian woodland; a beck – arising from at least two springs (‘sources’ on the OS map) at the base of the limestone plateau to the South – which flows through and has been used to create a pond; vegetable and flower gardens; plus lawns (some mown, some not). We have planted native trees to create woodland, scrub and hedges – in 2001 and in 2018; hazels and alder blackthorn in the ‘old wood’ to create an understorey; and wildflower seeds in the open areas of the 2018 wood.
A list, then. To understand the meaning of this list, this catalogue of lives, I work my way down slowly, taking time to allow a picture of each named creature to enter my mind; to hear the subject singing or calling, if that is what it does; to see them en masse, in a shape-shifting murmuration, or flitting through the hawthorns, or dotting the mud at the bottom of the pond.
For theirs are ‘Compelling and interacting stories’ – and I have written their names here so that I will not forget.

As for plants, it is true that ‘if you provide the right conditions, they will come’: cuckoo flowers, orchids, great burnett, and more, suddenly appearing to delight us. And the six-year old trees – particularly the apple trees – in the ‘Three-score years + 10’ 2018 wood are already being colonised by lichens. In time, as I grow better at identifying these complex organisms, I hope to include a list of lichens too – for they’re the epitome of ‘interacting stories’.
Postscript:The moorhens:
A few days after I posted this, I thought I was hallucinating – a moorhen wandered past the kitchen window. About a week later, there was a nest amongst the reeds. Then 4 eggs. But only one moorhen. However, the trailcam gave away their secret – there were, of course, two birds, who met up and changed places in the evening and night. There is now always one on the nest, the other occasionally seen in the boggy patch in the next-door field, or lurking at the edge of the pond. The brooding period is 20-21 days, so we look forward to seeing babies. Meanwhile, the mallard sitting on her nest on the island, just a couple of metres from the moorhens, has hatched 8 chicks after 28 days – and after a day pottering around the pond, has taken them away, who knows where? We wish them luck and a happy life. The diversity and number of invertebrates in the pond has no doubt had a set-back …
Today, World Book Day 2024, the paperback edition of my ‘Solway book’ is published. The hardback came out in 2020, during lockdown – which was not the best time to be bringing a book into the world! But despite that, I have received many, many comments – emails, contacts through the F&S website, letters, and invitations to speak about the book – from readers who have enjoyed finding out more about this little-known, little-researched and crooked finger of estuary and sea that divides and unites Scotland and England.
So, I invite you too to find out more, and to enjoy reading and dipping into The Fresh and the Salt: from geological timescales to present-day (and, perhaps, the future); from aerial view to the microscopic; from miners and navvies to ships’-pilots; from the silk-lined burrows of mudshrimps to fossil reptile footprints and the colours of sphagnum mosses. And then come and visit this beautiful and unusual area of NW England and SW Scotland, to enjoy its sweeping shores, saltmarshes, raised bogs and sculpted sandstone.
There are many reviews of the book, and extra material – photos, videos and more – on the related website. And the book can be obtained from any bookshop, or through various online shops.

There is a self-portrait of William Mitchell (1823–1900) in Maryport’s Maritime Museum [1], painted in 1899. Most of Mitchell’s other portraits are rather lacking in life, but he clearly knew himself better than his other subjects: the lower part of his broad face with its long, strong nose is hidden by a bush of white beard and moustache, his forehead by a soft-brimmed black hat, but he has a powerful and rather accusing stare. He arrived in Maryport, from County Down, when he was seventeen, one of many Irish migrants who were fleeing the famine at that time, and found work in the Engine Works of the Maryport & Carlisle Railway, painting the company’s coat-of-arms – its logo – onto the carriages and locomotives. He also started to paint maritime scenes, but he didn’t leave his job (by then he was Foreman Painter) with the M&CR for another twenty years, by which time his paintings had become popular and he was receiving many commissions.
‘Mitchell of Maryport’ is especially well-known for his maritime paintings – ships being built, ships at sea, sailing ships being pulled by a steam-tug, ships wrecked or in the process of being wrecked with their crew and passengers being saved. Portraits and caricatures, Lake District landscapes, Mitchell painted them too, many as commissions – but the maritime paintings are populated with people and animals, who catch the eye and make one laugh. There are men gesticulating, children with hoops, old men leaning against walls and chatting, young men sitting on the edge of the pier, legs dangling over the water as they fish, oblivious to the racket around them. There are gulls, mere hints of white wings and black heads, squabbling over detritus in the water or resting on floating branches.
The Launch of the Collingwood
However, it is the domestic mammals that I love most. Two dogs with open, snarling mouths are leaping towards a man who has raised a stick against them; a lad pulls at the man’s arm, trying to stop him. On the road above them, a large furry dog sits impassively watching the drama below. But the same two snarling dogs are in another painting, and this time the boy is missing, the man fights off the animals on his own.
In one of several versions of The Launch of the Collingwood [2] (which Mitchell himself copied from W. Brown – who may have been his mentor), two growling mastiffs are restrained from attacking in each other, their masters pulling them back and trapping them between their knees. Elsewhere, a small cheerful dog prances besides its owner. There are donkeys, pulling carts or patiently waiting between the shafts. There are horses, standing with hanging heads.
My favourites, though are the cattle. Why are there cattle standing or lying on the slipways? There was a long history of cattle being driven on foot over the shallow waths [3] across the inner Firth like that near Bowness, or across the River Eden, but here in the harbour, it becomes apparent that they have been passengers on a ship. The story is at first hard to unravel – there seems to be a dead cow floating in the water, its legs pointing stiffly at the sky. But a friend of mine pointed out that the gunwhale (the raised side of the ship that acts as a protective barrier) of the ship Gipsy has been lowered, and there are men standing there looking down. The (live) cow has been pushed off the ship – hence the great splash of water surrounding it – and will surely be guided to the slip, for nearby, there is a small skiff alongside which one of the two crew holds another cow as the boat is punted towards the shore. There are two versions of this painting, The Graving Bank, in Maryport’s Shipping Brow Gallery [4]: in one painting the cow has large horns, in the other it has no horns (its head is hard to make out – is it being towed backwards, held by its tail?) And as you would expect, there are many interested onlookers, standing or sitting on the harbour wall – you can almost hear their banter and their laughter. The owner is likely the man standing on the slip and waving his arms. The onshore cattle are unconcerned. My friend suggested that the cattle boat might have come from Ireland, and indeed it is labelled as such by maritime historian David Bridgwater in his interesting blog [5] about the ship-builders of Maryport: “The Brig Gypsy [sic] Discharging Cattle from Ireland onto the Graving Bank. With the Barque Airey ready for the broadside launching in the background in 1837.”
So many of Mitchell’s paintings encourage you to look closely, to enjoy the tiny details, and imagine the unfolding story. Not all his stories are amusing though: some are grim, like the demasted ship wallowing in the stormy sea and, potentially much worse, the wreck of the Danmark in the Atlantic. The passengers, who have been rescued by small, open boats from the SS Missouri, are crammed together, wet and cold and frightened. But at least we know everyone was saved. The description (in the former Maritime Museum) notes that ‘every soul was saved. 735 persons, 65 mere children and under 11 years, 22 mere babies under 11 months’. And above the terrified mothers, a basket containing 4 of the ‘mere babies’ is being swung down to the rescue boat.
Mitchell was born two hundred years ago, and his paintings of ship and ship-building at Maryport give us detailed and intimate views of life in the town in the 19th century. Yet the activities of the people and the animals are not so different from what they would be doing today, and we can unpick and enjoy their stories.
His obituary in the West Cumberland News notes that ‘He was very industrious, and according to the records which he kept, had painted over 10,000 pictures.’ He was also industrious in other ways: he had had three wives and (possibly) at least twenty children, and he was contemplating marrying again just before he died.

Six o’clock, and the rooks and jackdaws are wheeling in the darkening sky, shrieking and cawing in a cacophony of sound, their attention focussed on the garden below. The football-rattle clatter of vigilant magpies adds another layer of sound. Like snowflakes, pale feathers drift down for several minutes from the sky. On the lawn, a female sparrowhawk struts amongst the pearly fluff of an exploded collared dove, and darts at the three magpies who are daring to challenge her for her kill. After a few minutes, they give up and fly away; the black corvids continue shouting from above, but then they too drift away in twos and threes, and the hawk is left alone, to tear beakfuls of flesh from her prey. She pulls at the carcase for nearly three-quarters of an hour, and when she has finished only a pale plate of feathers remains to hint at its meal.
Sparrowhawks regularly flash through the garden and over the field, the speed of their flight sometimes so fast as to register sub-liminally; collared doves, of which we have many, provide a good meal. The hawks seem uninterested in sparrows, although blue-tits make an occasional snack. (And now I discover, from the RSPB/DorlingKindersley bird book, that ‘males take tits and finches, females thrushes and pigeons’; a new and fascinating fact!) The local buzzards continue to harass the rook colony when the rooklings hatch, and occasionally a kestrel hovers, wings flickering, high above the ‘new wood’ where the voles reign. I am ambivalent about the voles: yes, we are honoured that they like to live and breed in the wilder areas – but they are less welcome when they destroy the flowers of the snakes-head fritillaries, or burrow in the soil of the greenhouse and polytunnel.
This has been the Year of the Mole, too, with mounds of soft brown soil being thrown up all round the small-holding – even, bizarrely, on the island in the pond. Hedgehogs have returned, snuffling loudly in the dusk and, thankfully, no longer seen in the day: whatever disease struck them down previously must finally have disappeared. The bats, pipistrelles, are numerous and active as before.
But this has been the first year that we have had no swallows nesting at all. Indeed, there have been only a few pairs in the village, and the house-martin numbers have plummeted. The tawny owls ignored the nestboxes (which made perfect homes for jackdaws instead) and seemed to abandon the village and its surrounds altogether – but last night, in late October, we finally heard a pair calling to each other in the distance. The good news is that a heron has often been seen flying ponderously overhead, and surely visits the pond when we’re not looking.
Mallard nesting
Yet again, a female mallard risked nesting among the grasses and reeds on the island in the pond, despite the proximity to the rookery. For four weeks she lay flattened over her eggs, barely visible apart from a vigilantly beady eye, until one day her enormous brood of 11 ducklings hatched and were seen rapidly scurrying after her in the shallow water of the droughty beck. Where did she lead them? Who knows!
One of the ‘No-mow’ areasAfter mowing and removing the grass
Various of the no-mow areas in the garden produced surprises this year: in two of them new orchids appeared, and small grasshoppers had flown in too. The wildflower areas near the pond and in the ‘new wood’ were rich in plantains, oxeye daisies, pink campion and clover, and the previously unimpressive patches of yellow rattle have spread and proliferated, the dry brown seed-pods rattling satisfyingly in the late summer.

The ‘new wood’, the ‘Three-score years + 10’ wood, was planted in February 2018.

It’s now in its sixth growing season, and continually delights and astonishes us: some of the birches and alders are at least 20 feet high, and the hawthorn thickets and hedge are rich and dense and protective.
Alders and birchesOne of the hawthorn thicketsTall birch near the firepit
Chiffchaffs, blackcaps, willow warblers, four species of tit, chaffinches and greenfinches, tree and house-sparrows, blackbirds and thrushes – all regularly visit; and the butterflies – orange-tips laying eggs on the proliferating cuckoo-flowers in Spring, and the red admirals, tortoiseshells and meadow browns in late Summer – make us thankful, yet again, that we decided to turn this area of pasture into mixed woodland.
Fearsome puss moth caterpillar
No poplar hawk caterpillars on the black poplars this year, even though adults were identified in the moth-trap: the tree was given a reprieve and grew almost unchecked, its leaves munched only by one fat, overly-dramatic, puss moth caterpillar in July. Insect life thrives amongst the longer grasses.

As in previous years recently, very dry conditions have struck in the Spring. In the garden, vegetables have struggled and the potato crop almost failed, producing only little bullets instead of large sweet-fleshed ‘Vivaldi’. As usual, the drought caused the springs and the beck to diminish, and the pond gradually to reduce to mudflats and a thin trickle of water for several weeks. Sadly, but as expected, this was unattractive to dragonflies. Impossible to know if the tadpoles survived to fully metamorphose, although we have subsequently seen medium-sized frogs, and even a couple of toads, amongst the vegetation. But an exciting ‘first’ was the arrival of two giant water-beetles, Dytiscus, who are presumably feasting on the gammarids and flatworms. Eventually, the rains returned, and the pond looks like a pond once more.
Dytiscus (bottom centre) from Furneaux’s ‘Life in Ponds and Streams’ 1911
And the rain benefitted the fruit, both soft and hard – it has been an exceptionally good year for apples, and for raspberries and red and black currants (not so good for the strawberries though, which became balls of soggy, grey mildew and, past their best as plants in any case, have been dug up).
Raspberry ‘thicket’ flourishing
As I write this, the hawthorns, wild roses, and guelder rose trees are laden with red jewels of berries and the local children have collected large bags of conkers. The ‘wild’ raspberry thicket continues to produce fruit. Flocks of fieldfares are chack-ing in the hedges, joined by the first of the redwings. The pinkfooted and barnacle geese are flying over in large skeins, wink-wink-ing and yelping to each other, coming here to escape the Arctic winter. Herring gulls cruise inquisitively overhead and, improbably large, swirl and settle on nearby fields where slurry is being sprayed.
During the biggest Spring tides of the year, often in September, the height of the water in the Solway Firth might change by almost 10 metres – that’s nearly 33 feet – during the course of one tidal cycle. And there are of course two tidal cycles each day, so twice a day an enormous volume of water, a mixture of salt and fresh (from the many rivers that empty into the Firth from both the Scottish and English sides), rushes in and out, and up and down the shores.
But every tide is different: some of the Spring tides may range from a high of about 8 metres down to a low of about 1 metre; and twice a month, in between the excesses of the Springs, are the mild and unassuming Neaps (for further explanation about tides see the first section of the post on tidal power [1])
Even more confusing, if you are planning activities on the Cumbrian Solway shore, is the difference in tidal range as you move NE towards the Upper Solway; here the estuary becomes shallower, its bed ever-changing due to the wandering channels of the Rivers Esk and Eden [2]. Here, too, the timings of high and low water are very different from those at, for example, Silloth further to the South-West: the great shallow bowl of Moricambe Bay and the bay between Bowness and Glasson Point take time to fill and empty (see ‘Bores on the Solway’ for more on this [3])
***
Two of my favourite Solway activities are leading low-tide shorewalks at Allonby Bay [4] and rowing in the Bowness Belle, a St Ayles skiff, on the Upper Solway at Port Carlisle. The first, obviously, requires very low Spring tides so that we have plenty of time to explore the honeycomb worm (Sabellaria) reefs [5] at the bottom of the shore. The second requires a good high tide so that we can launch the boat from the slipway or from the edge of the saltmarsh, without having to manhandle the boat trailer down a long stretch of squelchy foreshore.
For the shorewalk on April 23rd we took advantage of the Spring low tide to walk the surprisingly long distance down the shore to the Sabellaria reef, and spent time finding Breadcrumb Sponges, Burrowing Anemones, predatory Dogwhelks, tube-building Mason worms and the like.

In actual fact, the tide was not quite as low as predicted, as the barometric pressure was low [6].
Oyster lays at low Spring tide, Dubmill
Neverthless, we found plenty to look at and chat about, and on the way back up the shore looked at boulders coated with young mussels, and commented on the lines of wooden posts, near the upper intertidal area, that once supported cages of growing oysters.

One week later, April 30th, the tidal charts showed the Neap low tide would be rather feeble (see chart above), so I went back to make a comparison. There would have been no low-tide shorewalk that day! Low tide was now at about 2.2 metres above Chart Datum; the previous week it had been at about 0.9m – what a difference 4 feet makes!
Oyster lays at low Neap tide, Dubmill
Where we had guddled previously in the lagoons, the reefs and the large erratic boulder, Hanging Stone, that marks their edge were now completely invisible beneath the water. The posts of the oyster lays stood with their bases in the sea, so I was confined to the pebbly middle reaches of the intertidal shore. Nobody could have guessed what an amazingly diverse array of animals and their architecture lay beneath the quiet surface; nobody would even think to imagine what a busy-ness of feeding, mating, defaecating, and other behaviours, was happening out of sight.
(We spend some time on the lowtide shorewalks looking for clues about the animals’ behaviour when they were covered by the tide – identifying the trails, like mountain-bike tyre-marks, of ragworm species large and small; finding the green ‘blobs’ of their eggs and the yellow vase-shaped eggcases of dogwhelks; noting the sideways scurry-marks of crabs; and the thin strings of sandy Sabellaria poo that showed they were at the mouths of their protective tubes, and feeding…)
***
The Bowness Belle, a St Ayles skiff
In contrast, the row on the 30th had to be cancelled because launching the skiff at hightide at Port Carlisle would have been impossible, for the height of the full tide was at only about 1.5 metres, way down the shore and leaving the slipway and the edges of the saltmarsh high (if not quite dry).

A week previously on April 23rd the Firth had risen to more than 5 metres and by high water, the Firth was slopping over the marsh – making disembarking, and subsequent cleaning of the boat, much easier!

6. Atmospheric pressure: each millibar (now called a hectopascal) of pressure changes the height of the sea-level by 1 centimetre. The standard is set at 1013hPa – lower barometric pressure allows the water to rise higher; higher barometric pressure depresses the rise. If pressure varies between 950 and 1050 hPa the expected variation in sea level due to air pressure is between +63 cm and -37 cm around mean sea level. Wind and weather also affect the tides – strong onshore winds can drive waves further up the shore
“You can tell barnie poo from pinks’ poo because the pinks’ is greenish,” Frank bends down and points to the soft cylinders of pinkfoot goose poo that are scattered on the cropped turf. “Barnies’ are brownish. But they all have white at one end” (a white ‘paste’ of uric acid crystals, formed from excess nitrogen excreted from the caecum).
Barnacle geese grazing (at Caerlaverock)Goose poo
I’ve joined Frank Mawby for his WeBS count – the national Wetland Bird Survey – which he carries out every month, irrespective of the weather, on his ‘patch’ of Border, Calvo and Skinburness saltmarshes at the edge of Moricambe Bay.
When I arrived, three wildfowlers, dressed in camo jackets and caps and waterproof trousers were coming off the marsh, accompanied by their muddy dogs. It was the final day of the wildfowl shooting season [2]: one man had a couple of geese in his bag, but the others carried only their shotguns; they stood around, chatting cheerfully, before climbing into pickups and four-wheel drives. One of them stayed to chat to me while I waited – he knew all about the WeBS counts, he knew Frank (everyone knows Frank!); he was glad, but possibly also rather sad, that for the next six months he wouldn’t be getting up early to be out on the marsh at dawn …
South Solway Wildfowlers permitted here
We watched a kestrel swoop down into the marsh grasses then swerve up again to hover, a flicker of russet, by the gate. It was mid-February and still cold, but larks were singing, and there were trilling calls of redshank; a small murmurration of starlings took off from the field behind us, the flock shape-shifting before they dropped and settled once more.
Frank arrived, unloaded his telescope and tripod from the car, and we set off over the marsh. Frank is several years older than I am, and spry. For many years he was Site Manager of the North Cumbria NNRs for English Nature (now Natural England), and his knowledge and understanding of peatlands, birds and marshes is both practical and encyclopedic. He has been a driving force at Watchtree Nature Reserve since its inception after the foot-and-mouth epidemic of 2001, is President of the Carlisle Natural History Society, and over the years he has helped me with projects, blog-posts and my book [1]. I am rather in awe of Frank! Now, I’m trying not to seem wimp-ish as I look for easier spots to jump across the ditches; Frank meanwhile is carrying a bag, and the tripod on his shoulder (but he does have the assistance of two walking-poles).
Geese are grazers, partial to young sweet grass (and also, to the disgust of local farmers, young winter wheat and barley). Frank shows me the short, brighter spikes of Pulcinellia (Common Saltmarsh Grass) that are starting to push through the thin brown deposit of mud on the surface of the marsh. “It’s just shooting now, it’s a pioneer species. But fescue grass outcompetes it, and needs to be grazed down – I keep telling NE [Natural England] the marsh could hold 500 cattle instead of the 250 permitted.” In places the fescue has formed a dense thatch, which the cattle will ignore, and which smothers any Pulcinellia that would provide food for the geese.
Creeks on Calvo MarshCalvo at dawn in 2011The incoming tide
Our first stop to set up the ‘scope is Border Marsh. We’ve squished through mud, jumped creeks, avoided tussocks and reached the short green sward. There is a slight breeze; the tide is already rising but the mudbanks are still exposed each side of the Waver estuary.
Frank provides a constant commentary; he points out a little flock of dunlin lifting off and swirling about. “Can’t quite count the little beggars yet!” They settle again on the mud and potter about, and I do a quick count – but I’m way off the expert’s estimate of 300. “There’s 40-50 grey plover among them too. Dumpy little birds – distinctive in flight by that black area under the wing.” I count again, “in fives, then again in twos – they’re nicely spread out”. Both species are scurrying on the mud. This time my estimate is closer to Frank’s. He writes the numbers in his notebook.
Frank on the marsh by Moricambe Bay
The wildfowler had mentioned ‘pricked’ geese, not a term I had heard during my previous visits to the marsh [2]. I spot a couple of geese on their own, not feeding or resting but wandering around. Frank says they have probably been pricked –shot at, and hit by a few pieces of steel shot; damaged but not killed. It’s good to know that the use of lead shot has been banned on the estuaries, and over the wetlands for several years (but I was surprised because I thought lead shot had been banned everywhere – apparently not, and it is still causing deaths by poisoning of wild birds and other animals). A lone pink-footed goose flies over us, circling, calling as it flies: “Possibly its mate was killed or pricked, and it’s come back to look for it.” From tomorrow they will be safe, and before long they will fly back to the Arctic to breed.
The creeks are still dry-bottomed, with cracks in the mud; some are decorated with goose footprints. But the tide is now coming in, brown and scummy-edged, flowing fast, and we need to keep an eye on those creeks.
There are shelduck on the far side of the estuary and I look through the ‘scope for a clearer picture. They are handsome ducks, striking in their black and white and brown livery. Thirty barnacle geese come flying over from further inland, calling, ‘yapping’ – unlike the ‘wink, wink, wink’ of the pink-footed geese.
Now there are 300-400 dunlin on a far spit that projects from the Newton Arlosh marsh, a spit which has extended and grassed over in the past 10 years, Frank tells me. He laughs: “The things I thought might be birds over there are just clumps of samphire”.
To the North-West, across the Solway, the top of Criffel is hidden, decapitated by grey, flat-bottomed cloud. A band of lemon-yellow light is sandwiched between grey above the Scottish coast. Oyster catchers are probing, and redshanks are foraging along the edge of the incoming tide. They are all duly counted and noted. A patch of sunlight is moving towards us like a spotlight, lighting the scummy foam; the pale grass shines, and the white-painted houses at Anthorn emerge from the greyness. A lark burst into song above us. A rock pipit – a first for me – flits along the side of a creek. Where it is difficult to see the details of distant birds, Frank says he often relies on “their jizz” – their behaviour, as well as their outline and shape – to make a good guess at the species; he has had plenty of experience, as he’s been doing these WeBS counts on the Solway for 36 years.
The flow of the tide has stemmed, the estuary is in stasis; water slops softly in the creeks, waiting for the Bay to start to empty. We move on, heading West towards Grune Point and the next observation point at the boundary of Calvo and Skinburness marshes. There’s a fast-moving orange shape in the Bay beyond Grune: it’s one of the RNLI ribs, its bow raised as it speeds and turns, crew standing upright in their yellow suits. Sunday is their day for practising rescues.

There are more creeks to jump, a barbed-wire fence to squeeze through, more rushes, more tussocks, and then we reach an extensive area where the gorse has been flailed and cut according to a conservation management-plan – to Frank’s annoyance as it was an important area for stonechats and linnets. We set up the ‘scope again on slightly raised ground, sheltered from the keen wind by the remaining gorse. “There are usually 60-70 curlews in this area,” he says, and at first we seen none, but later 24 are counted. Their trilling always thrills. Unusually, no cormorants are drying their wings on the posts of the WW2 target out in the Bay. Soon, they will return to breed and there will likely be a nest on every one of the posts.
Since the tide has stopped rising, and we’re no longer in danger of being cut off by over-topping creeks, we head down to the post-and-wire fence that edges the water – dropping down two tiers of the marsh [3] to spy on any birds that may have been out of sight on the lower tier. We find ducks, including pintails, and a half-dozen pinkfeet geese are wandering around. “They might have got a bit of shot in the wrong place, I can see some feathers scattered around”. There is the ongoing worry of the highly-transmissible avian ‘flu [6]. “With the amount of shooting in the last few days, it’s difficult to know whether the dead birds are from ‘flu or if they’ve been shot.”
Cormorants on the posts of the WWII target, Moricambe Bay (October 2018)
A small flock of dunlin and grey plover are resting at the edge of the marsh, but it seems likely that they are the same as the ones we saw earlier. We don’t want to count them twice. Over on Grune Point, ‘Spike’ will be doing the WeBS counts for the peninsula. And “there’s a couple who do the count on the other side of Moricambe Bay at Anthorn. But nobody does Newton Arlosh marsh – it’s a very long walk to the edge, and you can get in trouble there on the big tides.”
All around the British coast, once a month and whatever the weather, there are more than 3000 birders, with their telescopes and binoculars, counting the numbers of the wetland birds on their patch. These data are entered on a dedicated section of the BTO website, and the record goes goes back to 1947 (and was digitised in 1969).
According to the WeBS information [4], the term waterbirds ‘includes wildfowl (ducks, geese and swans), waders, rails, divers, grebes, cormorants and herons. Gulls and terns are optionally included.’ The data show ‘populations and trends in abundance and distribution. The network of sites legally protected for their importance to wintering waterbirds depends fundamentally on the WeBS counts.’
Annual summaries and newsletters can be downloaded from the BTO website [5]. For example, the newsletter for Autumn 2022 has an article on the effect of avian flu on the geese that migrate to the Solway during the autumn and winter (even now, in March 2023, dead geese are being washed up – thankfully in small numbers compared with a year ago). A map in the Annual Report for 2019/20 shows that the Solway Estuary has the seventh highest annual number of non-breeding waterbirds in the UK.
We’ve been out on the marshes for a couple of hours, and coffee-time is long overdue. I’m surprised to see how far we have wandered, and the walk back, with repeated detours to find narrower crossing-points of creeks, seems lengthy. Frank admits that he’s not sure how much longer he will carry on doing the surveys – the tripod and kit are heavy, the terrain is rough – and he wants to find someone else to train. We see a Little Egret in the distance, startlingly white against the drab late-winter colours of the marsh, and the kestrel is still hovering and hunting near the gate. Then we’re back at the cars and peeling off layers of waterproofs and fleeces, and finding our thermoses. WeBS count done for another month.

[2] See section on Wildfowling in Chapter 9 of The Fresh and the Salthttps://thefreshandthesalt.co.uk/chapter-nine/. I’ve been out twice on the marshes with a wildfowler, talked to others, and also talked to people who ‘oversee’ it on the Scottish and English sides. Note that wildfowling is closely regulated, through the issuing of licences, in England; less so in Scotland. Whatever your own views, it is a subject that is not ‘black or white’ – there are nuances, and my own opinion was better-informed, and altered, after my conversations. The final chapter of The Fresh and the Salt goes into some detail…
“Grubby seagulls.” The words are engraved on a pale slab on Maryport pier, in an unusual and beautiful italic script.
Why “grubby”? There are gulls perched on the metal posts that edge the quay. There are gulls pecking amongst the pebbles and wrack along the muddy margins of the estuary. But they aren’t grubby – coastal gulls are clean, whether Greater Black-backed, Herring Gulls juvenile or adult, Black-headed or even Little Gulls.
Gulls on the old oyster-lines, with Criffel in the background across the Solway
Growing up in Cornwall, in the ‘fifties and ‘sixties, it was rare to see gulls inland. When they did gather on the fields, my parents would always say, “Must be a storm at sea”. Gulls would also appear at ploughing-time, to forage in the newly-exposed soil. But it has become usual now to find gulls way inland, apparently just as at home in towns and cities as on the coast. They have been lured by rubbish tips and dustbins, by fields sprayed with slurry, and by plentiful urban nesting-sites on the rooftops and chimneys. Even far from the coast, in Oxfordshire, gulls circle over the city. Their habits have become ‘grubby’.
Worse, they spread bacterial diseases like Salmonella in their faeces, which can enter the water supply [1,2 ]. In the 1980s my colleague Pat Monaghan, and her research team at the University of Glasgow’s Zoology Department, looked at ways of protecting the city’s water from roosting and defaecating gulls: the most effective deterrent was to broadcast recordings of the birds screaming in distress as though they were being attacked. Out for a run around the reservoirs at Milngavie, I was occasionally shocked out of my mindless pounding by those harsh, panicked calls; in the early days of the experiment, gulls would lift off from the banks and the water, but it became apparent that, with time, they grew accustomed to their invisible compatriot ‘crying wolf’.
Greater Black-backed gull
My own interest in gulls as conveyors of disease started early, linked to my growing enthusiasm for parasitology, or more specifically helminthology, the study of parasitic worms. My undergraduate summer project was on the prevalence of parasitic worm larvae in periwinkles, Littorina littorea, on the shore, and their pathological effect on the snails. When infected snails were dissected, dozens, sometimes hundreds, of larvae spilled out into the dish: pale and almost transparent or orange with carotenoids, depending on the species. There were sausage-shaped redia larvae, filled to bursting with the next, dispersive larval stage, the cercariae. And there were cercariae ready to leave, oval-bodied with tails, those of the colourless Cryptocotyle lingua with its black eye-spots easily distinguished from the orange Himasthla secunda. When ready, they would burst out of the snail and swim away to find a new ‘host’, usually a rockpool fish, on which to encyst – and wait. For parasitic worms, life-cycles are complicated matters [3], games of chance [4 ] – so the more offspring they can produce, the more likely it is that they will succeed to propagate their species; and if this means waiting, semi-dormant, to be eaten by a suitable host, so be it. So a gull, paddling in the shallows, catches and eats a small fish, and the parasite encysted in the fish’s skin is stimulated by the warmth and digestive juices in the gull’s gut to grow and develop into an adult worm. When fertilised, the worm’s eggs embryonate and pass out in the gull’s faeces; they hatch, and these newly-hatched miracidia larvae infect a snail.
Winkles, Littorina littorea; the two large ones might well be parasitised
Even now, I note with interest where gulls are congregating on intertidal rocks and, where possible, I go there to check for Littorina. I look for unusually large snails – the parasite larvae often cause gigantism – and pull the snail quickly off the rock, trying to catch sight of its foot before it is hidden beneath the shield-like operculum; if the foot is orange-brown instead of white, the periwinkle is almost sure to be infected. But gulls, and humans, can eat parasitised periwinkles without fear, for the larvae still need that next stage, the encystment on a fish, to become infective
Surprisingly, for Herring Gulls seem ubiquitous, the numbers of several species of gull are in decline; Herring Gulls are on the Red List, Greater Black-backs on Amber [5 ,6]. One likely reason for their decline is the change in management of council rubbish tips – formerly an easy source of food – which have been covered over for years; but another suggestion is that it might also be due to the reduction in fish waste thrown out from trawlers, due to the quota system [7]. (The increase in predation on chip- and pasty-eating tourists doesn’t seem to be slowing the rate of decline.) Figures for the effect of the 2022 H5N1 Avian Influenza epidemic – which has killed thousands of sea-birds including skuas, gannets, guillemots and barnacle geese – are not yet available for gulls, although anecdotal reports for this Solway area seem to suggest that few dead gulls have been found (but listen to more about this Highly Pathogenic H5 virus and its effect on birds on the BBC Inside Science podcast [8]).
The ‘Gullery’ at Rockliffe Marsh, where gulls’ nests are protected by fencing to keep the cattle out
Gulls are intelligent, like crows, and can work out ways of accessing food – pasty-grabbing aside. They prise mussels off rocks and then head for an area of smooth hard ground – a tarmac road, a carpark, the stony surface of a pier – and fly high and release the shellfish. If the two valves of the shell do not break apart or crack, the gull will fly down, pick up the mussel, and repeat the trick until it’s able to extract the soft edible contents with its hooked yellow beak. Recently, when looking down into the clear water of Loch Shieldaig, I was delighted to see the pale orange globes of several sea-urchins, Echinus esculentis, half-hidden amongst the gently-swaying wrack. There had been a full moon a couple of nights previously, and the spring tides had a large rise and fall: at low water, an urchin was clearly visible across the bay, attached to the side of the rocky reef where the seals hauled out. On the following day, as the tide dropped, I watched a herring gull paddling intently by the reef, its head cocked to one side. Then it took off and rose almost vertically before plummeting, head first, into the water – emerging with an urchin held awkwardly in its beak. Weighed down by the cumbersome object, it flew towards the shore and then rose again to drop its prey down onto the shingle. For the next half-hour it ripped at the shattered urchin, pulling out long streamers of innards; walking round its feast, peering, pecking, gulping.
Less successful was the attempt of two adult herring gulls to steal a half-loaf of stale bread from our bird-table. Gulls, mostly herring gulls, regularly fly over our small-holding in North-West Cumbria, usually above the tree-tops, yet constantly checking out our field and the rookery for opportune snacks. Surprisingly, unlike their furious response to the buzzards, the rooks pay them no attention and in twenty-odd years I have never seen a gull take a rookling or descend to ground level, even though they scavenge on the adjacent slurry-sprayed pastures. But that lump of bread was clearly irresistible. One gull had landed on the roof of the barn across the yard; another flew low to make a preliminary recce. The bird-table was close to a tall yew, and was attached to metal railings that were topped with curlicued spikes. Over and over, the gulls took turns in trying to drop down then level out and angle their flight to avoid the hazards, side-slipping, even hovering; over and over they failed, returning to the roof to fidget, heads tilting, eyeing up the problem. It took them more than twenty minutes to admit defeat; I admit to disappointment too, because I was looking forward to seeing how they dealt with the weight and awkward shape.
On a still day the air over the field climbs upwards in an organised spiral, invisible to humans. On the flat plane of the ground we cannot feel it, but up there, coasting slowly, a single gull senses that stirring. She spreads her wings, tilting them to capture the full power of the lift; with the smallest of adjustments, she relaxes into the thermal, allowing herself to be carried upwards, in ever-rising loops. No other gulls had been present, none in view. But within minutes, they appear, singly or in groups, edging their way into the current; rising, stiff-winged, and quietly. There has been no calling, no vocal communication – yet, somehow, distant gulls have seen one of their kind allowing herself to be carried upwards, into a space where they all can play. And so they fly in to become part of that silent spiral, playing with the air, allowing it to lift them effortlessly, without moving their wings. It is easy to imagine that they might close their eyes, embraced by this three-dimensional world. But soon the thermal tilts and carries them sideways; the current falters. The gulls’ dreams are broken, and the birds angle their wrists and fly away, singly and in groups.
To see gulls overhead, and to watch their observant flight; to hear them calling: this always makes me happy and invokes a sense of longing, perhaps because it takes me back to my childhood near the Cornish coast. Henry Wismayer, reviewing Keltner’s book on ‘awe’ and what it means [9], notes that ‘one recurring motif … is that it precipitates “ego death,” the dissolution of the self.’ I clearly remember that the first time I experienced an overwhelming feeling of awe (although I would not then have called it that) was when I was about seven years old, and looking down at the Looe estuary in the slanting pink light of dusk, taking in that whole, inter-related scene of the water, the fishing-boats and houses and the wooded hills, and telling my father that I wanted to be ‘broken up and scattered in little pieces’ (the dissolution of self) so as to be part of that scene – like the gulls that were beating out towards the sea, their wings glinting.
How can one recover that sense of awe in today’s frenetic world of short attention-spans and clamouring discourse? Can I, as a writer and a former practising scientist, step outside the need to observe and to comment and to explain? Wismayer again: ‘The tension between awe and science could never be fully reconciled because, in the end, ambiguity was awe’s operating principle.’ [8] Perhaps the suspension of disbelief and the suppression of ‘ego’ has become too hard.
Meanwhile, I try to keep my eyes, and mind, open. As Mark Cocker wrote, when reviewing my ‘Solway book’, ‘Like a hungry gull, Ann Lingard explores [the] shoreline for every living detail that catches her eye.’ [10 ]. Mostly, away from the mudflats and marshes, I manage to stay fairly clean.

Again, we didn’t gain final approval, but it stimulated the setting up a committee (for which I was a consultant) to develop ideas for a full-scale exhibition about parasites. Ideas and plans were well-advanced – but in the end, funding was unavailable! (I think dinosaurs were the winners.)

A local Cumberland councillor, who sits on the Board of the cross-border Solway Firth Partnership, often refers to the Cumbrian coast as being the ‘soft side’ of the Firth, in contrast to the rockier Scottish, side. And once you have travelled North-East from Maryport, the softness and malleability of the Cumbrian coastline is very apparent: shingle slides into sand, which slips into mudflats, backed by dunes or saltmarshes.
During high spring tides and stormy weather, the brown, sediment-laden waves pound against the margins, shifting the sand, gnawing at the mudflats and pummelling the edges of the saltmarshes. Year by year – and more so now that ‘extreme’ weather events are occurring – the border between land and not-land is shifting. The coast road from Maryport to Silloth is continually being threatened, and is sometimes closed to be cleared of pebbles and seaweed or – in the worst cases – have its seaward side shored up. The loss of the coast road is a major inconvenience; the potential loss of houses and shops a disaster for human lives and livelihoods. So how can they be protected from the force and height of the water?
Mangrove swamps would be effective and a very pleasant and interesting addition to the Solway coast … but meanwhile saltmarshes certainly do their bit to dissipate the force of the waves. Leaving aside these natural (and importantly, carbon-sequestering) coastal defences, the usual answer is ‘hard engineering’, the construction of unnatural defences using concrete or rocks.
Around the British archipelago’s coast, horrifyingly large volumes of cement, requiring massive costs in quarrying, crushing, transport and the use of energy have been poured and moulded into various types of defensive wall to hold back the sea. Some of these constructions are more effective than others, as illustrated in a simple set of experiments in a wave tank by researchers at the Jeremy Benn Pacific Trust (JBA Trust). In the video, which is on YouTube, the researchers set up different shapes of hard engineering at one end of the tank, and then measure the volume of water that has overtopped the defences after 5 waves. For example, for a ‘beach with a sea wall’, the overtopping volume is 50ml; for a wall with a sloped revetment, like the new concrete defences at Dubmill Point, considerably more – 125ml;
The sloped concrete revetment by Seacroft farm, Dubmill Point, during a stormy high tide
for a wall with a stepped revetment – just like the steps on the long promenade at Silloth (see below) – 100 ml.
The ‘stepped’ promenade at Silloth
But, for a wall with a recurved top – rather similar to that of the concrete promenade at Maryport – no water overtops the defences in the research tank. (I’m not entirely convinced by the reality of this, having got soaked by spray on Maryport prom, during a stormy high tide!)
The (slightly) recurved top of Maryport promenade
And also at the high end of protection against the tank’s waves are gabions – wire cages of boulders – and rock armour (only 5ml overtopped). This a very nice demonstration of how the rocks reduce the energy and therefore eroding power of the waves, breaking up the flow and forcing it in many different directions simultaneously.
Away from the wave-tank, bunds of gabions and rock armour have been constructed along vulnerable stretches of the Cumbrian Solway coast from Whitehaven to Allonby Bay, to Skinburness and Grune Point.
Intact gabions at Crosscanonby (left); displaced and damaged gabions at Crosscanonby (top) and at Dubmill Point
But the wire gabions, containing smaller stones, that protected the historic saltpans and the coast road at Crosscanonby, were severely damaged – ripped apart and their contents scattered – by one of the winter storms; in their place the defences have been repaired during the past year with boulders of a harder rock, an igneous dolerite probably from somewhere along the Whin Sill (my thanks to geologist Ian Francis for the identification).
Dolerite rock armour being put in place at Crosscanonby, 2022
The use of dolerite is a new departure, because nearly all of the other stretches of rock armour are of limestone – and this is where rock armour becomes fun. Fossils! Corals, solitary and colonial; crinoids; brachiopods; and ‘trace fossils’ – they are all there, if you have the patience and courage to clamber amongst the boulders to search.
Trace fossils at Parton
I first became aware of fossils in limestone rock armour some years ago when I stopped at the shore-side carpark at Parton, just North of Whitehaven; these were ‘trace fossils’, traces left by an animal rather than of an animal. Imagine, say, a polychaete worm or a bivalve mollusc that lives in a burrow in the sand. It’s sedentary, staying put in one place, so, rather than roaming around on the surface to look for food (and exposing its own vulnerability as prey), it waits for food to come to it. In the case of the polychaete, the worm extends its crown of tentacles like a net in the water, or sweeps its tentacles over the surface of the sand around the burrow. The burrowing bivalve, on the other hand, has a muscular tube, the siphon (rather like an elephant’s trunk in its mobility and sensitivity) which hoovers up food particles from the sand around its burrow. These feeding movements could leave the sort of arcs of indentation that are seen in the Parton traces. What class of animal left the fossilised traces of its feeding? It’s impossible to tell although geologists, hedging their bets, often refer to the marks as ‘zoophycos’.
Limestone rock armour, North Shore, Whitehaven
At North Shore beach, Whitehaven, the fossils in the rock armour are even more impressive. As I scrambled over the rough, pale boulders I was asked a couple of times what I was doing by local dog-walkers, who were then surprised and impressed when they saw the (previously unnoticed) fossils of solitary and colonial corals. There were thick bands of colonial corals; there were curving longitudinal sections, and the packed circles of colonies broken transversally. It was easy to imagine the colourful masses of the little filter-feeders extending their tentacles to capture food borne by the incoming tide. Here too were pale curved sections through the dished shells of brachiopods, sometimes solitary, sometimes clumped together by the currents of the warm Carboniferous sea, to lie on the sediment surface.
Whitehaven: crinoids, brachiopods, and solitary and colonial corals
Further along the shore, there is a sudden sharp demarcation where the limestone blocks have been replaced by boulders of pink Shap granite, studded with large shining crystals; perhaps there was a BOGOF on a few truckloads of the stone.
Shap pink granite armour
But there is more limestone rock armour a little further North-East, dumped in an attempt to protect the Maryport golf course at Netherhall from being eaten by the sea: more fossil corals, brachiopods, and sections of ‘sea lilies’, crinoid echinoderms. Here, too, are piles of bricks and broken concrete, tossed aside contemptuously by the waves.
Dubmill Point; the shuttered farmhouse, and debris thrown across the road
Further up the coast again, to Dubmill Point at the north end of Allonby Bay, to huge sloping revetments of concrete, which have been repaired and extended yet again; despite this, the stormy waves throw large pebbles and sand onto the coast road, and hurl spray high over the farmhouse on the Point. You pass the ‘Road Closed’ signs at your own peril.
North of Dubmill: a mixture of groynes, concrete ‘steps’, and 2 types of rock armour
The concrete gives way to rock armour again, in which fossils are scarce. On a sunny day a few summers ago, I noticed a figure in a skin-coloured bathing suit (perhaps) sunbathing against the radiating warmth of the stones.
And so to Skinburness and the finger-like promontory of Grune Point that protects the western edge of the shallow expanse of Moricambe Bay. Here the rock armour is a tumbled line of large limestone boulders, some with a thin red crust and speckled with rusting iron-rich nodules.
Grune Point; limestone rock armour; half-buried groyne; and limestone pebbles on the beach
The shore here is dazzlingly white in the sunshine, and glimmers even on a dark and cloudy day, for it is covered in pebbles of limestone that have been churned and cleaned by the waves. The pebbles are round and smooth, and too numerous to have been broken off and eroded from the large boulders; they are likely the ‘quarried cobble’ referred to in the Cumbria Coastal Strategy for Silloth to Skinburness (see note below).
Grune: a thin iron-bearing crust; pebbles on the shore containing corals
As with all this rock armour, I try to discover where the limestone was quarried, and when it was brought to the coast; indeed, how the rocks and pebbles were placed in situ – for there are often no roads, and clearly barges were not used. It has been – so far – almost impossible to discover these simple facts [but see important note below], despite asking the County Highways Department and highways representatives on Borough Councils. But Grune Point is part of the Solway Coast AONB and, as I expected, the former Manager, Dr Brian Irving, knew the answer: the rock came from the large limestone quarries at Rowrah, and was deposited in the late 1990s… But that is all I learnt. Yet to know its geographical origins within the county would be to know more about the geological history of the stone, and to be able to guess at the reasons for the inclusions of iron ore and different species of animals.
Whatever their origins, the piles of limestone boulders at the top of Cumbria’s ‘soft’ shores look incongruous; but perhaps it helps to think of them as a man-made complement to the ring of limestone that surrounds the rocks of the Lakeland Fells.

Chapter 1 of the Solway Review, on Coastal Change, includes links to pdfs of the Cumbria Coastal Strategies, Technical Appraisals: this might sound dull, but the documents are very interesting, looking at the type of coast, the attempts to mitigate damage, and with discussions about possible future work. The PDFs for Maryport to Dubmill, and Silloth to Grnue, are especially worth downloading.
Dry stone wallers need to be pragmatists, building around or over problem areas, or incorporating boulders too big to move.
A ‘jumping wall’, Orton in the Westmorland Dales
At Bents, near Newbiggin-on-Lune on the edge of the Westmorland Dales, red sandstone and pale limestone are strikingly juxtaposed. Huge rounded knolls and whalebacks of faded red-brown sandstone, mottled with white lichen, push up out of the moorland and pasture. And running alongside them, over them, around them, leaving narrow paths beside them, occasionally incorporating a boulder’s bulk in the boundary, is the purposeful line of a limestone wall; a barrier between the grazed green farmland and the moor. The wall is tall and well-fettled, built of shallow, sharp-edged plates of limestone; it is a double wall, with large flat through-stones, and coping-stones that are tightly-packed and tilted. High and solid, it is a daunting challenge even for adventurous sheep.
BentsBentsBents: unused limestone
At the eastern end, near Bents farm, names have been carved in the sandstone boulders. Many are weathered and, part-obscured by lichen, are difficult to read; the beautifully-engraved J Smith (or is it Smillie?) Bolland dates back to 1888; other names are even older.
Nearby, layered shelves of limestone – the origin of the stones for the wall – peep out of the eroded side of a hill. Here it’s easy to see the dramatic mix of the two types of rock, the Ashfell Sandstone Formation, which is part of the Great Scar Limestone Group. According to the information on the Cumbria GeoConservation website, “ The Ashfell Sandstone Formation is interpreted as the deposits of a river-delta system that spread into the shallow carbonate seas that covered this area during the early Carboniferous. Thick sandstone layers, like the one at Bents, may represent sands deposited in large river channels or as offshore sand bars. The reddish colour is due to the presence of iron oxide and suggests deposition near an arid shoreline.”
Limestone outcrop above the sandstoneUsing the sandstone for the wall
Where the limestone wall jumps to the top of a Bents boulder, the waller has incorporated chunky sandstone blocks to give the free end extra stability and majesty: limestone and sandstone intermingling their organic and inorganic origins.
Not far away, next to Natural England’s Great Asby Reserve , we are looking for something marked on the OS map as ‘Thunderstone’. On our left, a rubbly, part-tumbled limestone wall, and the clatter and growl of an approaching, as-yet hidden, quad bike. The noise stops, there is some muttering and swearing, and a man, round-faced and with thick brown hair, dressed in a mud-smeared jacket, appears by a gap in the wall. Although surprised to see us, he grins and asks, ‘All right, then?’, and we chat about the weather, and how the yows will always break down the walls. ‘Look at this!’ He gestures at the fallen stones, which he has come to fix. ‘See, it’s just bloody rubble round here – no good for walling.’ It’s true, on this stretch the limestone is fragmented and irregular, and the wall is only a single layer thick and barely four feet high: a determined tup could send it flying. We ask about the thunderstone and are told, ‘it’s just along there, you’ll see it on the corner’. And so it is, a smoothed, rounded boulder with the wall built around and on top of it. It’s a little underwhelming in terms of size, but its provenance is greater – an ‘erratic’, a boulder that was once caught up in the ice of a moving glacier; a boulder that was seized from another area, a different type of rock – Shap granite – carried away and dropped where it didn’t belong; and now incorporated in a dry stone limestone wall. [2]
‘Thunderstone’ in a wall near Great Asby Scar
Although it might seem odd that the farmer’s wall was ‘bloody rubble’ compared with the grandeur of the nearby and more recent wall around the Great Asby Scar Reserve, this reflects the properties of the local rock – wallers use the rock that is ‘to hand’. The pavements on the Scar are themselves very varied in structure and appearance, depending on how the limey skeletons were deposited and subsequently eroded. This new wall around the Reserve’s perimeter is nearly two metres high, built of blocky stones, with two layers of projecting throughs, and sturdy, slanting coping stones. It is a text-book example of ‘how to build a dry stone wall’.
‘Dry Stone Walling, a practical handbook’ [1] makes surprisingly gripping reading! I read it at breakfast and over lunch, enjoying the technical terms and their local variations, showing diagrams to my husband (who has done a fair bit of walling himself).
‘Dry stone walls are semi-flexible structures,’ Brooks and Adcock explain, ‘with the stones settling over time. The basic principles involved in building a dry stone wall are aimed at reducing the potential for movement during this settlement.’
The wall that encloses the Great Asby Reserve Great Asby Reserve wall: a ‘textbook’ example of walling
So there are the footings, which support two faces of stone courses; these are held together with throughs that straddle the wall, connecting one face with the other, ‘tying the two faces together in a single unit’ and stopping them bulging outwards. The interior of the wall is filled with rocks – without the filling (also known as packing or hearting), the face stones would settle inwards and the wall would collapse into the centre. Finally, a row of coping or topping stones caps the wall, weighing down and bonding the faces below, and protecting them and the filling ‘from the weather, animals and people’. The angle of each vertical face to the horizontal is the ‘batter’, for which a frame or template is sometimes built. There are many variations in style or height or shape, depending on the local stone and what is required of the wall – sheep (especially Herdwicks) are more agile than cattle and need a higher barrier.
Waller Arthur Robinson talks with humour about long stones and flat-sided stones, and the ‘golden rule’ of wall-building, placing the stones “one over two, and two over one” in a delightful ‘Countrystride‘ podcast with Mark Richardson [3].
Meandering wall near Great AsbyMeanders near Potts Gill, Little Asby
The Great Asby walls are tall and ‘tight’ – they march across the moor with straight lines and sharp corners, but walls nearer to the road are freer and more curvaceous, as they drop down into the shallow valley. Walls wiggle to avoid obstacles, such as sinkholes or springs or patches of bog. In areas where there is a shortage of stone and the wall is only one stone thick, wiggles might also be constructed to give the wall strength, against the lateral pressure of the wind. (Such sinuously-wiggling walls, usually built of brick rather than of stone, are known as ‘crinkle-crankle’ walls.)
Last summer, while walking past Opinan, near Laide on the NW coast of Scotland, we stopped to chat to a woman who was clearing vegetation off a single-thickness drystane wall right by her house. The stones there were sea-worn boulders, balanced apparently precariously on each other, and she said that she had been told that because the wall looked unsteady, with gaps revealing the view on the further side, sheep would not climb it. (Our conversation led, of course, to Herdwicks – for it turned out that the woman, who had lived there for 30 years, originally came from Cumbria.) In their book, Brooks and Adcock also refer to this style of wall: ‘Single dyking is surprisingly stable, but looks so unsteady that all stock, including the notoriously adventurous black-faced sheep, are supposed to be deterred from climbing it’.

Limestone is rarely used in single-thickness walls – it’s more usual to use tougher stone like granite (as at Kippford on the Scottish side of the Solway) – but on the fellside amongst The Clouds near Ravenstonedale, there are scrappy limestone walls, some single, some built from stones cleared from the fields around the now-derelict Harry’s House. Many of the walls not ageing well, and are strung about with posts and wire.

I’ve written elsewhere about the grikes and clints of my local limestone pavement at Clints Crags, but it is the dry stone walls along the northern approach that I love most. They urge me to examine them, carefully; there is a strong sense of human stories, and of the wallers’ understanding of the stone and the land around them. The walls each side of the narrow, grassy, occasionally boggy, track differ markedly from each other, indicative of different wallers for different landowners.
The track to Clints
On one side a stretch of wall is intact, constructed of chunky blocks and with large coping stones. There is an unusual pit, looking man-made rather than a natural sink-hole, in the field beyond. The fraying blue twine that fastens the nearby metal gate to its sandstone stoop has been chewed by the sheep to make a tangled knot, so I climb over, and poke around in the shallow, rectangular depression in the field. It has clearly been a small quarry, hacked out by the wallers as a source of stone: water-worn vertical joints and horizontal layers have presented the limestone in handy blocks, ready for prising out and manoeuvring to the wall.
On the way to ClintsThe ‘quarry’ in the fieldThe quarry
Further along the track, and abruptly, the copings vanish and the courses of stones on the face are loose and ill-fitting. In places the wall is scarcely double, more of a hybrid with a double base and single upper part; many of the stones are thin and flaky. Not all are limestone – there are broken pieces of terracotta floor tiles, still with cement adhering; there are occasional small round ‘erratics’ of grey granite; and other stones coated with a red crust, which I can’t identify.
The wall on the left had been a low jumble of stone, but now it gains height and becomes tight and topped. It wiggles sharply – and when I climb up to look, I see that the waller has had to divert around a sinkhole. Further on, the wall rises and falls, taking its footing on a small hummocky outcrop.
The neat wall on my right now degenerates into little more than a hopeful boundary. Sheep and the weather and old age have taken their toll on its integrity. In the field beyond, a Border Leicester tup, long-legged and Roman-nosed, stares at me imperiously from where he is standing possessively by two Swaledale ewes. I wish him ‘good morning’ and stare back, and then the light glints on something smooth and out-of-place in the interior of the tumbled wall: not a bone, but the stem and part of the bowl of a clay pipe.

The RSPB’s Campfield Reserve near Bowness on the Upper Solway is a perfect place for a writing workshop, especially if you want to ‘experience’, think about, and write about saltmarshes; they form a land- and sea-scape that most people probably do not consider as particularly interesting or important. Saltmarshes are, according to poet Norman Nicholson, ‘neither land proper, nor sea proper’.
My third ‘saltmarsh writing workshop’ was held at Campfield in mid-September, timed to coincide with a low spring tide so that we would have plenty of time to explore the marsh and mudflats without having to worry about the incoming sea.
As always, my reason for running the workshop is to encourage writers to see saltmarshes in a new way, and hopefully begin to understand why they are so special – and to find a way of conveying this to other people, in their writing and conversation. The key to this is, to use Attenborough’s important statement: ‘No-one will protect what they don’t care about; and no-one will care aboutwhat they have never experienced’. Saltmarshes need our protection.
It was a day of changing patterns of light, a shifting beam that picked out fields in Scotland, pale ochre bands of sand that floored the estuary, the far-distant glimmer of the Firth, the partly-demolished towers of Chapelcross. We spent time outside – and returned mid-afternoon to watch the now high tide reaching up through the creeks into the marsh – and time inside, in the Wetlands Centre’s meeting room. It was a day of laughter, and the exchange of ideas and viewpoints (nine people offering nine completely different ways of viewing the saltmarsh and mudflats), some intense work – plus a rescued jellyfish, and a water-filled welly. I introduced everyone to some new words, too – and was asked if I could make a list so that the anyone who wanted could refer back to them, and perhaps use them in their writing.
I also agreed to post some images as aides memoires, and some links to articles that were mentioned. So, here we are, some words and pictures…
The marsh:
Some words that we used: accretion, erosion; stratification and history, ‘stories’; ‘topping tides’ and ‘mucky tides’; tiers, and pioneers; ‘merse bergs’; creeks and dubs.
The fractal edge, intercut with creeks; and the expanding marsh at Rockcliffe between the Rivers Eden & the Esk. For more on my gyroplane flight, see this post.

A ‘classic’ saltmarsh has three tiers, formed as it grows outwards (accretes) and upwards, gathering and trapping and compacting sediment. The new edge, next to the estuary, is stabilised by the growth of pioneer plants like samphire, Salicornia, and the ‘invasive non-native’ grass, Spartina (it originally came from America) which trap sediment between their roots and in the ‘stationary layer’ of water at their base.

The different tiers have characteristically different vegetation, the less salt-tolerant species at the top (like gorse, rushes); many of the flowering plants (salt-tolerant ie halophiles) are in the middle layer, flowering at different times of year (only a few asters were in flower when we were there).

Sediment is deposited over the years, decades, even centuries: each layer tells a story – of weather, climate, sea-level, human activity.
The tops were once this high above the surface: Rockliffe marshBuried fences at Grune PointTree-trunks and baulks of timber, carried up to the top of Rockcliffe marsh during winter storms
But the crenellated edges of the marsh – the creek-mouths and the dubs (‘pools’ or hollows) – dissipate the energy of the waves. Saltmarshes are an important intermediary between the water and the land.

Human activity on the saltmarshes includes farming – the grazing of livestock during the summer months. On the Cumbrian coast, marshes are divided into stints, the grazing of which is auctioned each year.

Wildfowling is permitted on Calvo & Border Marshes and Rockcliffe on the English side, between September-February; permits are necessary and the numbers and species of birds regarded as targets are strictly regulated. The rules are different on the Scottish side, although tightly regulated at Caerlaverock, for instance. See the final chapter of The Fresh and the Salt for a discussion of this (nuanced) topic.

The mud:
Microphytobenthos (MPB): the bacteria in the top layer of the mud and the marsh, which migrate up and down depending on the amount of light and the state of the tide. Photosynthesis – using, thus ‘storing’, carbon dioxide – the top layer of bacteria and the middle layer of cyanobacteria need light and oxygen; sulphide-using bacteria in the black, anoxic layer, do not, and do not photosynthesise.
Mudshrimps (Corophium), mudsnails, ragworms, and lugworms – live in or on the mud.

Tides and tidal bores:
We touched on this briefly: bores on the R Nith, the R Wampool, and up near Burgh marsh, for example There are images and weblinks in this blogpost, and videos of the bore on the R Wampool here (scroll down to the bottom of the page).

Discussions and insights into ‘new nature writing’: just a few references here (there are more recent articles too, but mostly ‘re-inventing the wheel’ – the topic has been around for a while and it’s easy to get bogged-down).
This is now a topic of major importance: bacteria and plannts sequester carbon dioxide, taking it out of the atmosphere, during photosynthesis, and as they die and are buried, so that carbon is stored. Damage to saltmarshes (like damage to peatbogs) releases the stored carbon again, as carbon dioxide. Many efforts are being made to map the extent of marshes around the coast, and to protect and restore them where possible.
Hopefully, after our writing workshop and discussion, you’ll now understand a bit more about the drama and dynamics and uniqueness of the saltmarshes, and will stand up for them when they are under threat.
And spread the word in your conversations and writing; pass on your experience. Remember, ‘No-one will protect what they don’t care about; and no-one will care aboutwhat they have never experienced’.
