Wraysbury in the Mist, and Leafy Lichens

Willow Reflections in the Mist
Willow Reflections in the Mist

Well, after 7 Vole Patrol postings, and some very cold, wet and early mornings, I felt like enjoying a nature walk in the sunshine, away from Woodmice. But as I left town I found myself in fog, not too thick to be sure, but fog nonetheless.

I was rewarded, however, with the lovely sight of the willows along the lake seeming to float, isolated in the smooth sea of soft gray.

As the mist slowly lifted, a pair of Goosanders and a pair of Goldeneye (the male displaying, the female in tow a yard behind) could be seen through the mirk.

I couldn’t get away from the mammals, either. I was pleased to see not just the usual Muntjac prints along the path, but Roe Deer too.  A little way further, and there was a Wood Mouse hopping in a relaxed way across the path, before diving down its hole.

Among the birds calling were Green Woodpecker (finely), Great Tit, Song Thrush, Cetti’s Warbler. A Heron and a Parakeet flew overhead. Wood Pigeons and Carrion Crows watched warily.

The damp air had another good effect: the lichens looked wonderful, and even the bristly Ramalina were soft.

It was nice to see the lichens flourishing so close to London (and Heathrow): these little fungus/alga plants are very sensitive to pollution, and when I was a boy they were almost impossible to find anywhere near a city, so conservation stories can be happy.

All-round Amateur Dilettante Nature-lovers…

A reader of the RSPB’s members’ magazine, Nature’s Home, wrote in a letter to the editor that “If I had my time again I would try and be an all-round naturalist, instead of just a birdwatcher.” [Mike Strickland, Summer 2014 issue, ‘Your view’ page 13.]  Well, good on you, Mr Strickland. He went on to praise “such ‘all-round giants’ as Gilbert White and Charles Darwin.” White wrote the Natural History of Selborne, covering topics such as the swallows that flew round his nice house, how to get a garden growing (buy several cartloads of manure – literally – and use it to build a raised veggie bed), the doings of a hibernating tortoise, and whether swallows spend the winter underwater or in holes somewhere. Darwin wrote about everything from Galapagos Finches to earthworms and human emotions, with a lot of time on dogs, pigeons, barnacles and natural selection.

Clearly Mr Strickland had a point. If we’re going to be rounded naturalists, we need to observe whatever is around us – slime moulds and lichens, aphids and fireblight, hoglice and cuckoospit, not just the elegant courtship dances of Great Crested Grebes.

The editor assured Mr Strickland that “The study of other forms of wildlife has definitely become more mainstream with more and more birdwatchers also taking a keen interest in dragonflies, butterflies and moths. While other wildlife has been a feature of the RSPB magazine for quite some time, birds will definitely remain at its heart.”

The other forms of wildlife that, we learn, birdwatchers bother to look at are apparently dragonflies, butterflies and moths. That’s just two groups really – Odonata and Lepidoptera; both are large, day-flying, colourful, and conspicuous – just like birds, but without the feathers – differing only in being insects. Forgivable, I guess. They are, basically, the next best thing: easy to notice, out there when you want ’em (shame they don’t fly all year), and best of all, not too numerous.

I mean, suppose the average birder wanted to get into the beetles, the Coleoptera. They can be found all over the world, are quite often big and spectacular, don’t fly much, are generally black or brown, and are mostly so small you need a hand-lens or microscope, and are so numerous in species that you need to take them to the museum expert to get identified for you. Not terribly convenient, but definitely important.

The biologist J.B.S. Haldane is supposed once to have said, in response to a natural theologian who wondered what one could conclude about God from the study of nature: “An inordinate fondness for beetles.” Since there are about 400,000 species of beetle, one species in every four is a beetle, and a rational Martian visiting Earth would conclude that the planet’s ecosystem designer must have had six legs and a hard waterproof exoskeleton, presumably the joke that Haldane had in mind.

If we are going to be less species-ist than Haldane’s Coleopteran Creator, we need to cast our net wider than Aves, Odonata and Lepidoptera. The streets round here are planted with cherries, mainly; there are a few whitebeams, a rowan or two, a line of ash trees, and a few foreign hazels, they could be the American hazel, must check when they fruit.  Under the cherries, the observant naturalist can note that Shepherd’s purse, the delightfully named Capsella bursa-pastoris (guess the poor man had so little money, it could fit in those tiny capsules) is already in fruit, soon to scatter its miniature seeds, and April isn’t even over: weeds have to be quick to survive on dry ground, perhaps. The ash trees support a lichen flora which is far more diverse than the basic Lecanora conizaeoides (low grey scaly lichen, no English name) that survived the pollution of the twentieth century; the trees have circles of Common Orange Lichen (Xanthoria parietina) and little patches of a grey leafy Parmelia lichen. And it doesn’t just consist of birds and other conspicuous day-flying objects, either. If that’s all we know to look at, we’re definitely amateur dilettante nature-lovers. Amateur is the French for lover, by the way, and dilettante is the Italian for someone that takes (idle) pleasure in something, the word is related to ‘delight’. Curious that both words should mean “ignorant dabbler” in English. But curiously appropriate, perhaps.
