From Druridge Bay to Roman York, via the Lizard Peninsular

Most of our work focuses on Druridge Bay: monitoring how the communities of invertebrates change over the years in ponds at Hauxley, how the number of wetlands  at Ellington Farm (the new Crown Estates name for Blakemoor Farm) vary with rainfall and quantifying the carbon capture across different pond types throughout the Bay. The ponds and wetlands certainly bury more carbon than the other habitats such as pasture or arable fields, but we need to check if that holds true in different regions of the UK or else we can’t say much beyond just the detail we have for Druridge. Pete and Scott have been venturing further afield, first to the Lizard Peninsular in Devon where many of the wetlands are technically Mediterranean, at least in their plant life. Last week Pete was down in Yorkshire, with the Yorkshire Wildlife Trust taking sediment cores from small ponds on Askham Bog. The Bog is on the outskirts of York, and has long been used for peat digging and livestock, but retains a mysterious feel, especially amongst the denser scrub where a wrong turning can have you face to face with half wild horses. I don’t know which half is wild, though when I met them a few years back the front ends seemed plenty dangerous enough. Pete opted for cores from slightly less hazardous terrain, distinctive small rectangular ponds, some inside an enclosure which creates the undignified impression that he is a type of livestock.

 

The pond’s origins are uncertain, with some suggestions that these may be peat excavations going back as far as Roman York. The important criterion for selecting these sites is their small size. We want to characterise the carbon dynamics of smaller wetlands because these are the ones missing from carbon budgets, although such wetlands are ubiquitous and numerous. The Lizard and Askham Bog are lowland sites, to match the broad landscape of Druridge. We also plan to include some sites in Norfolk, which should add a hotter, drier biogeography into the mix. Lowland Northumberland, Yorkshire, Norfolk and Devon will make a good start to capture the variation in carbon burial around the country.  The differences between wetlands around Druridge Bay is striking. Regional variations from cool northern, to hot southern should only add to this mix

The hebridean inhabitants of Hauxley

Winter’s grip is loosening. The ground is still sodden, and scabbed over with dead flower stems and grass blades barely green from the cold but the air is full of bird song. The little birds have kicked off, finches  and buntings, tree sparrows and wrens. Work is well underway at Hauxley too, on the new straw build hide. The burning down of the old hide turned out to be a blessing. It was a beautiful wooden building, substantial and snug. I still treasure the strange grand opening breakfast as the great and the good of respectable Northumberland squeezed into its main room for scrambled eggs and bacon. With so many more people coming to Hauxley it rapidly became obvious that a bigger building would be better with classrooms and a cafe so that the bacon and eggs were not a one off.

The western edge of the reserve has been enlarged too now, following a land purchase and a flock of pretty Hebridean sheep are now at work grazing, or they would be if they did not follow any passer- by in the hope of a feed. They have the deepest brown wool, fluffed up akin to a Cruft’s poodle and propelled on delicate legs so that from a distance they appear to be animated woollen bobbles that have come adrift from a hat. The new land is largely stark grassland, but like so much nature conservation think ten or twenty years ahead. New woodland and scrub will form a rich fringe to the reserve and hopefully saline grassland can take over the inundated edges. Room for some new ponds too, perhaps larger, permanent ones in contrast to the shallow flashes and pools that already ring the car park. A mix is best. The winter flashes around the car park area riot of summer flowers but some deeper ponds would be good for submerged species such as Potamogeton pondweeds. Meantime the JCB started work levelling and preparing the brow where the old hide was incinerated. You can check progress on the Wildlife Trust’s special straw build Facebook group; the videos may by students from Hirst Park Middle school are a joy.

Nature and the naturists: Druridge Bay as the last outpost before respectable Northumberland

Despite the many kilometres of written text in wildlife conservation manuals, or terabytes of e-text detailing how to manage sites, one subject which affects many a nature reserve is missing from the literature:  nature reserves and nudists. It is largely a coastal specialism, a bit like salt marshes and barnacles; I doubt there are many regular naturist spots on Cheviot.  However for anyone responsible for sand dune sites around the coast of Britain the sights you can see in sand dunes can be a source of problems. There have been some famous nature versus naturist clashes, Dawlish warren in Devon the most well known. A key point is that the naturists have often been there first, it is the conservationists who are the interlopers. Those of you who watched Robson Green’s  “More Tales From Northumberland” on the 16^th will have been treated to a flash of dune nudity as skinny dippers braved the North sea for what has now been established as a regular North East Skinny Dip, a charity fund raiser.  Cheeky, but not really naturists. However the Bay does have a longer standing, more discrete nudist scene. You’ll not see it sign posted or on TV, for it is not entirely respectable, not sanctioned nor tame. Which is part of the charm of the Bay. I regularly drive up to Druridge Bay and the journey north from Newcastle is an odd mix. All the way up, until beyond Lynemouth you are still in the gravitational pull of the industrial north east. Even if there isn’t the industry anymore, the culture and history has roots deep into the ground and the coal. With this culture a love of the countryside, but not respectable: pigeons and ferreting, rough shooting and angling. North of Amble respectable Northumberland begins, almost exactly with the area of Outstanding Natural beauty designation. In-between lies the Bay, a transition, scarred but created by industry, shifting with the tides, sinking over the coal seams, with silent smelters and anti-tank bocks. A contentious arc of very different opinions and delights.  Part of the bay’s character. The respectable skinny dippers are a fleeting presence: the Bay has other heritages too.

No vultures at Druridge Bay, but a trip to Martian Spain finds some familiar plants.

Pete, Scott and I have had the great good fortune of a trip to Huesca, in northern Spain, for the 6^th European Pond Conference Network meeting. Huesca retains its romano-medieval feel, as if the heat has kept it from expanding beyond the old city walls into the deserts to the south or Pyrenees foothills to the north. Take the desert road south and you come to the county of Monegros, which looks ideal as a film set for Star war’s Tatooine, but instead is known for its spaghetti westerns. The roadside services even affect a wild-west feel with wood balustrades and canopied terraces from which to keep an eye of strangers riding into town. There are at least 140 saline wetlands, called “salades”, pock marking the terrain, largely the result of solution of the limestone and gypsum topography, with the wind also blowing out the hollows. The aquifers are saline too, the hydrology and topography creating a remarkable scatter of salt wetlands deep inland, many of them part of a Natura 2000 designation. They have characteristic vegetation, salt loving xerohalophytes (dry and salt loving), including Atriplex species higher on the edges around the dissolved out drepessions, then distinct zones down to Salicornia patula as the final outpost before the salt crust. The Atriplex are the shrubs in the photo foreground above, the Salicornia the bright green clumps before the open expanse of the salades floor. If you walk down below the line of bluffs around the salades the further horizons cannot be seen and it is easy to this could be Mars with a little bit of gentle terra forming. The fine sediment crusts of the hollows are loaded with the eggs of specialist crustacean such as fairy shrimps, waiting for the rains, and vivid red darter dragonflies perch like sundials on the crackling vegetation. Superficially all very different from the verdant greens of north-east England’s coastline, with its sea frets and northern winds. However Atriplex and Salicornia are familiar species along our coast. Different species, yes, but the same zonation with Salicornia the outer pioneer on salt marshes at Holy Island and Alnmouth, whilst Atriplex species are all along the coast and in the fields at Druridge. However, in Northumberland, no vultures drifting casually overhead though, keeping half an eye on the unwary salades tourists, in we became mired in the cracking salt crust.

The creeping up on red darter dragonflies time of year

 

Red Common Darter dragonflies, Sympetrum striolatum,  may not have the glamour of their bigger brethren such as piratical Emperor Dragonfly or gaudy Southern Hawkers but there is an everyday charm and confiding jauntiness to them that conjures up August (...with an ominous hint of approaching autumn too). They are fond of basking on wooden fences and tables in the sunshine and they soon circle back to their perches if you disturb them. Creep up carefully and you can get very close. Often they waggle their heads, sometimes holding an inquisitive sideways look at you as they try to work out what you are. Their huge eyes, made up of lots of separate single facets called ommaditia, are very good for detecting movement as the shadow you cast crosses from each facet to the next. If they are not in the mood for being crept up on they will depart but they seem to appreciate the warm days of high summer as much as we do and mostly can’t be bothered. Their larvae are rather squat, sprawling critters, again lacking the submarine menace of the larger species. Instead they clamber amongst the debris and submerged plants in ponds.  There are several very similar species of red darters, including migratory rarities such as the Red-Veined Darter, but this far north most of them are the Common red. this one has the typical large yellow splashes on the side of the thorax which are a good ID tip. Black Darters turn up along the Bay sometimes too: they are small and fidgety compared to their red cousins. Darter Dragonflies will last long into the autumn if the days stay warm, but right now are busy enjoying the sunshine, whipping in tight, dog-fighting circles as males vie for supremacy or hovering briefly on the look-out for a mate. Autumn can wait.

"The small gilded fly doth lecher in my sight" (King Lear, nature lover)

Nature is famously good for us, with talk of “green gyms” (marketing speke for a walk in the countryside) and mental health.  The verdant green of a spring time woodland or flower strewn verge are a delight. I am less sure about the darkened woods of late summer as the leaves strip out all light or the wilder moors: Wuthering Heights, The Hound of the Baskervilles and Lorna Doon are not set high on the moors by accident. Nonetheless Druridge Bay has that overwhelming calm of sea and sky that King Lear could have done with instead of contemplating flies out in the storm. I have always assumed the “small gilded fly” he observed were Long-legged Flies, Dolichopodidae, perky, iridescent inhabitants of damp vegetation and exposed mud. They do a lot of letchering in sight (green bottles do not, so I’m ruling them out). The sun has brought out the more conspicuous Dolichopodiae in skipping, fizzing mobs. Most are very tricky to identify but one is not, Poecilobothrus nobilitatus, on account of the white wing tips of the males. These frantic suitors whirr and fan their wings to females, then hop and skip back and forth over the object of their amorous attention. However since they all tend to crowd together in the drying puddles and rims of the ponds the mob is a constant agitation of distracted flirting and collisions. As each fly shifts and twitches new neighbours jump into view so within seconds they seem to have lost sight of their intended.  They are also easily distracted trying to yank midge larvae out of the mud which they chew up with macerating mouth parts.  If you approach to abruptly the whole mess of flies scatters but lie down to watch and they will soon return to their choice patch of mud for another round of dancing.  They are flies of high summer’s hot days as the ponds dry down to squirming mud and a delight to watch.

The burnet moths cyber noir day out

The July warmth has unleashed a very special day along the dunes around the Druridge Bay Country Park; the burnet moths have hatched. They are not rare nor unfamiliar, but well worth the time to creep up and admire. The newly emerged are shimmering black winged, whilst their bodies are the deepest sable fur. Vivid red spots blotch their wings, five or six spots per forewing depending on the species. Antennae stand proud, a filigree segmented hook of which the finest blacksmith would be proud. They seem slightly out of place on the dunes, dressed for Frank Millar's Sin City. Seen against the yellow of Birds Foot Trefoil or gaudy purple-pink of the Bloody Cranesbill, the burnet moths add to a remarkably colourful dune-scape. Maybe the Burnets are more fin de siècle Gustav Klimt that contemporary cyber noir. The males whirr, slightly clumsily, low through the marram stems or cluster on thistles. They can detect a female in her cocoon even before she emerges and the males wait around to mate even as she hauls herself out. Here are a pair with the females white cocoon as their foot hold. They shimmer in the sun. The high summer butterflies are also out in force. Common Blues fizz  past, the more tentative Small Heaths flitter away from out under your feet and Ringlets bob low amongst the stems as if on the end of invisible strings. Walk the dune path south of Druridge Bay Country Park and you will find these beautiful insects in abundance. The burnets do not last long, their extraordinary looks maybe burn out too soon, befitting their vanity, which deserves your attention.
