Spring Migrants at Thursley Common

Eriophorum angustifolium, Bog Cotton, a plant of wild, wet and rugged places

A bright, breezy, and much cooler day (16 C, not 29 any more) was just perfect for a visit to Thursley. Perhaps many of the dragonflies decided not to fly: I saw one Common Darter and (I think) one Brown Hawker, and nothing else, so anyone who went along hoping to see the Hobbies hawking for dragonflies by the dozen will have had a wasted trip (and indeed I saw several extravagantly camouflaged types with gigantic telescopes standing about looking very bored).

But everything else was in full swing. A Cuckoo called from the pinewoods. A Curlew gave its marvellously wild, bubbling call from the open marsh. A Dartford Warbler gave me the best view ever of its rufous belly and long tail, as it sat low in a scrubby Birch, giving its rasping anxiety call repeatedly. I enjoyed the view through binoculars. By the time I remembered to take a photo it was half-hidden again.

A Stonechat gave its scratchy call from a small Birch, then hopped up to some Pine trees (so, a distant shot).

A few Chiffchaffs called from the woods; plenty of Whitethroats sang from the regenerating Birches that are encroaching on to the heath. A Green Woodpecker gave its fine laughing call.

So I heard three warblers today to add to the four yesterday, so seven singing warblers in 24 hours, a little bit special.

The lichen flora on the heath was quite beautiful, with Usnea beard lichen, leafy Parmelia, bristly Ramalina (all on old Heather), and elegant Cladonia potscourer, cup, and stalk lichens (three species).

A Linnet sang from the top of a Birch. Goldfinches twittered and flitted about.

And on the path out, a Hobby leapt from a tree right in front of me, where it had been sitting watching the bog pools,  waiting for dragonflies to come out and display themselves. It flew round and up, then circled, soaring, away to the south. Perhaps it was the one the twitchers had been waiting to see flying all morning.

Wonders of Wakehurst Place … and Loder Valley

Wakehurst Place is Kew Gardens in the countryside of Sussex, glowing on a cool but very sunny April day with spring all around: cowslips, primroses (pin and thrum, some antique school botany coming back to mind), bluebells, dog’s mercury, wood anemone; and a fine chorus of birds, with chiffchaff, blackcap, song thrush, blackbird and an assortment of noisy pheasants and wood pigeons for good measure.

Everything was coming into new leaf or into bloom: some plants like this Oak tree were doing both at once.

Being Kew, there are some very special plants about, not least the one-step-from-extinct Wollemi Pine from Australia, here growing happily with odd-shaped cones of both sexes in the English countryside.

In the attached Loder Valley nature reserve, a special treat: the Purple Toothwort, a parasitic plant in the Broomrape family, scarce in Britain and a new plant for me. It wasn’t present as a lone stalk: there were good big clusters of it on a steep clayey bank. I’m not sure what it was parasitising, though at this time of year it must surely be a woody plant, and brambles were close by.

By a gatepost, a large and fresh wild arum seemed to deserve its country name Lords and Ladies, standing gracefully fresh.

Back in the park, the silver birches perfectly set off the sea of bluebells.

Great trailing beards of lichen draggled down an oak trunk: it’s a rare sight in Europe, and all the more surprising in Sussex, not far from the pollution of Gatwick airport. Perhaps the prevailing winds keep the air clean, but in that case why are lichens so few in Hampshire and the southeast generally?

The park contains the extraordinary Millennium Seed Bank, complete with windows onto the world of toiling botanists, drying seeds and elegant specialised equipment – a gadget for pouring agar into stacks of Petri dishes, among others, and a dramatic selection of the world’s most bizarre seeds, like the very large and remarkably bottom-like Coco de Mer. It’s not one of the seeds in the seed bank just yet, as it is ‘recalcitrant’, refusing to be dried out so it can survive for centuries – it just dies instead.  Love stronger than death, or something.

Primroses by the River Usk

Having by good fortune been able to get away for a few days, we drove down to Monmouthshire and had a fine walk from the mediaeval stone bridge at Llangynidr along the beautiful River Usk.

The path had been damaged by the floods, but now the waters have receded the path is surrounded by primroses, celandines and wood anemones in delightful combination: specially good to see near a path, as so many wild primroses have vanished into thoughtless people’s gardens in England.

The River Usk – the Welsh name is from the same root as Whisky (Uisge), meaning simply ‘water’ – swirled over little rapids, a pied wagtail hawking for flies from the midstream rocks. Apparently the river names Exe and Wye share this origin; while Avon also just means ‘river’. In the days when people lived by just one river and rarely walked further than the nearest market town, ‘the river’ must have been a sufficient name.  As well as these etymologies, Tolkien would have liked the gnarled Old Forest oak trees beside the river, very mossy at the base, gripping the sandstone rocks with their roots.

Lichens grew to good size in the clean air. A piece of beard lichen (Usnea) had fallen from a branch on to the path; common cup lichen Cladonia conoiocraea grew on a mossy wall.
