Grimpo Nature Notes – August & July 2010

Inspired by the extreme adventures of Bear Grylls my youngest was determined to have an adventure all of his own. Setting out to reconnoitre a likely spot for a bivouac [picnic] we headed for a nearby copse of trees. Along the way we skirted the headlands of a number of fields, there between the hedge and crop a few arable flowers put on a display. The most pleasing of the bunch being clumps of Field pansy. The Field pansy is an increasingly common annual wildflower finding easy purchase on arable and disturbed ground. Pansies can display a very wide range of colour variations, today we were treated to pale cream petals gently streaked with chocolate stripes.

The copse lay in a characteristic damp North Shropshire hollow, inevitably we were quickly covered in mosquitoes and beat an orderly retreat. But before departing the hostile wood I spotted a peculiar buttercup-like flower. The five petals were the usual glossy bright yellow but the thin straggling stems lacked rigidity making the plant crawl across the ground. A buttercup, yes, but neither Creeping, the gardener’s terror nor Meadow, but the Lesser spearwort. The scientific name being Ranunculus flammula, the first meaning ‘frog like’, and the second referring to the ‘flame’ shaped leaves. A good number of the buttercup family such as Lesser celandine like damp conditions which possibly explains the frog like appellation.


Elsewhere in the wood Soft rush and Broad buckler fern crowns sent up their varied spikes and fronds. Damp pocketed woodlands like this have been preserved against agricultural advance growing as they do on difficult to drain land. The hollows are the result of the action of a great ice sheet that over lay the North Shropshire and Cheshire Plain 10,000 years ago. Varied deposits of glacial till have left behind peat lands, mosses and meres. Over towards Baggy Moor this low lying landscape has proved the haunt of our smallest bird of prey, the Merlin. It has a characteristic low, fast flight hunting down small song birds. The breeding pair numbers in Shropshire have been less than double figures for a long time, so a sight of this skilled pilot is a thrill. The Merlin lacks the moustaches of its bigger relative the Hobby and has distinctive black streaks on its brown chest.

Our wetlands generate swarms of insects and their accompanying bird predators. Making our way to another likely jungle setting, swooping streamer tailed air athletes feasted. At first we marvelled at the Swallows, but our accolades were saved for the Swifts. Matt black and uncompromising in the power of their curving progress, we were spared the slightly unnerving scream they make when flying over the breeding colony. Elsewhere a deep blue Emperor dragonfly was mesmerising a wildlife watcher with its pulsing hunting patrol flight. The last few months have been better for butterflies, Ringlets, Meadow browns and Gatekeepers all flying in good numbers. The Ringlet appears quite dark in flight but up close the female carries the most delightful eyed spots on its wings, rather like a half dozen RAF roundels. A darkening sky forces most of these tender creatures to ground, today’s weather was mixed and thoughts turned to home.

We gathered the first blackberries on our way back,  fat purple drupes, sweet washed by a brief shower. Some of the runners were still in flower ensuring a long season of pies, crumbles and red stained lips. Closing the door behind us we began planning for our next adventure, maybe this time we’ll go out for the whole afternoon!


Happy Wildlife Spotting, best wishes, Pete.

Grimpo Nature Notes July 2010

PB had suggested I take a walk along the canal and down to visit the Aston Locks nature reserve. Very good advice I concluded after a delightful stroll beside the beautiful and diverse bankside flora. I had hoped to catch a flash of azure, as reports of kingfishers had been made from both Heath Houses and the Boneworks.   I was not so lucky either in hoping to see curlews on my visit though they are around, my first encounter being the frothy cream heads of the Meadowsweet, confirmed by its red stems. Meadow sweet was used in mediaeval times to flavour mead though it’s name over time evolved to reflect it fondness for damp meadows, various parts of the flower carry different scents from the honey tinged flowers and the sharpness of the leaves. In stark contrast further along I spied the drooping purple flowers of the Bittersweet, also known as Woody Nightshade. Despite an attractive climbing habit the Bittersweet leaves smell of burnt rubber and of course the red berries are poisonous.

Wildflowers adopt a fantastic range of forms to take advantage of soil, sun and water. Birds Foot trefoil or more commonly called Eggs and Bacon, tends to grow low on disturbed soils, its yellow and red tinged flowers making a show of a plain area of grass. Along the towpath it is joined by red and white clover, now past their best but still contributing a bobble head of colour. With my eye trained into to spot the yellows, I realised I was a little early for the full show of the water lilies but they were on their way, and a little late for the flag iris who’s bulging seeds pods were ripening on the stem. But just in time for the silverweed, the flower is mildly similar to buttercup but with a livelier edge to the keenly coloured petals.

I had to reach for my plant book for the next few yards, a group of medium tall plants that all looked like nettles but the varying colour flower heads said different.  Finally I was able to distinguish Gipsywort, from which a fast black dye can be produced. Then White deadnettle, non stinging, propped up the left hand side of the stand of imitators. The square hairy stems of Purple loosestrife with its towering spike of red/pink whorls of flowers were next. Loosestrife derives its name from the Greek belief that it had a powerful calming effect on oxen.

Tangled through the plants invasive tendrils of Goosegrass or cleavers, bullied their way to the light. For such a vigorous plant it has such insignificant white flowers. I was pleased that as I moved towards the waters edge a finer and more delicate cousin of the Goosegrass was in flower, the Marsh bedstraw, it’s white four petalled blooms held by a thin tracery of stems and whorls of leaves. The bedstraws all have the characteristic whorl of leaves, along some of our local lanes I have seen the yellow flowered Lady’s bedstraw and in the Berwyns can be found the tiny Heath bedstraw.

Just before I turned for home I spotted a tuft of blue flowered plants which on closer inspection I recognised as Skullcap. The name derives from the shape of the flower which is reminiscent of a Roman soldier’s leather helmet. The skullcap ironically is a member of the same family as the deadnettles that had caused me problems earlier; we have another, Black horehound growing by the compost heap in the garden.


In other local gardens, treats from the last month include Bullfinches, Long tailed tits and broods of blue tits, fledging now, so fingers crossed. Finally an intriguing report of a Nightjar has been received near Threadneedle Street, this secretive nocturnal bird has a distinctive frog like call and a wide gaping mouth to catch moths on the wing.

As ever a jam packed month, make sure you spare at least one balmy evening to commune with nature at her brightest.  

Happy Wildlife Spotting, best wishes, Pete.

Last of the Summer Wine - Coalmoor

 Or maybe that should be ‘Last of the Summer Rain’. Our visit to Coalmoor last Friday (July 16, 2010) ended in a sudden downpour just as we arrived back at the mini-bus after a day’s surveying this Veolia owned site.

I call this post ‘Last of the Summer Wine’ because, sadly, it is the last of our organised summer excursions onto the green spaces of Telford & Wrekin with the Wrekin Forest Volunteers. We still have our summer BBQ on the Top of The World, however, this coming Friday so let’s hope the rain stays off for then - it’s raining as I write.

So we now await the Autumn/Winter programme that I guess Pete at SWT is already working on and simultaneously grappling, no doubt, with the funding for it and other projects.
.
Seems odd I know to be talking about winter in the middle of summer but then it doesn’t seem to bother Selfridges - I’ve just heard they’re already selling Christmas baubles! Now that’s got to be so wrong on so many levels. There should be a law against it championed by perhaps The Christmas Police or maybe The Crackers & Bauble Bobbies.

Here I go drifting off on a massive tangent again, so steep we all have to dig our finger nails in!

Coalmoor 160710 001

So… yes… the Coalmoor site is owned and run by Veolia the waste and recycling experts, part of which is being turned into a natural habitat with pools and woodland mainly interspersed around its perimeter. Which is what we were there for, of course, to see what flora & fauna were colonising this charming little spot.

There’s still a lot of work to be done and much of the central part had seen recent and necessary activity and is at the moment what I’d call ‘brown’. But around the edges we saw many promising signs including a fine Fallow Deer who poked his head over the hill-top to see what the commotion was about and then he was gone! Buzzards circled majestically overhead whilst Magpies squabbled endlessly and lots of little things were on the wing too.

Small Skipper, Ringlet, Meadow Brown, Green-veined White and Comma were amongst the butterflies recorded. And I managed to pot a rather worn moth - the Shaded Broad-bar.

A few weird and wonderful creatures were also enjoying life at Coalmoor such as these small larvae feeding on Alder.

Coalmoor 160710 010

It was Tony who led me in the right direction when he said he felt sure they were a species of Sawfly, prompting me to investigate further using that magnificent resource; the interweb.

Oh, by-the-way; not wishing to run too far behind the times my long-standing friend (I do wish she’d sit down) Vera Wayfrommer recently bought a laptop. I called round the other day to see how she was getting on. Confused would have been the nicest way of putting it. The terminology had sent her into a right tizz. She was just placing a small piece of cheese at the side of the keyboard mumbling almost incoherently about feeds and mice and complaining she didn’t realise she had to do this! There’s no hope. I left quietly.

Ooops! Have I digressed again?

Anyway, little white fluffy caterpillars. Yes... turns out they’re White Alder Sawfly larvae - Eriocampa ovata - confirmed by the fact they were feeding on alder. The white fluffy stuff that covers them is something I haven’t come across before - it’s apparently called ‘flocculence’ and is a form of camouflage - makes them look like bird droppings. As they get bigger and closer to pupation the flocullence is shed and left dangling from the leaf. So there you go, every site we go to I find out something new, like how to use Graham’s monocular.

Coalmoor 160710 003

Actually that’s not me using Graham’s monocular, it’s Graham and he’s using his camera.

I didn’t realise we were so close to the power station but there it is with the cooling towers just poking above the tree-line.

Our foray brought many interesting flowering plants and grasses. Bristly Ox-Tongue and Ribbed Melilot to name but two.

And more caterpillars… these are the very common Cinnabar moth larvae on Ragwort.

And a 10-spot Ladybird.

Tea-break ran into lunch-break and then the dark clouds descended and we headed back to the bus.

Coalmoor is a very interesting site with lots of plant & creature potential over the coming years. Worthy of another trip next spring/summer.

Facebook

Did you know that Shropshire Wildlife Trust has its own Facebook page? Neither did I till Pete phoned me yesterday to ask if I could make a connection with our blog and forum. So I’ve done that and wondered if you’d like to join the group too? If you don’t have a Facebook page yourself you’ll need to set one up in order to connect but it’s free, quick, simple and painless. And if you already have an account then you just need to log in. This link will send you straight to the SWT group. Leave a message to say hello from the WuFuV's, etc.

Here’s the direct link:-
SWT Facebook Group (opens in a new window)

I will also place a link on the blog and the forum.

That’s all for now folks. Catch you all soon.

Grimpo Nature Notes from Pete Lambert


Grimpo Nature Notes July 2010

Recently my young family encouraged me to join them in a Canadian canoe trip down the Montgomeryshire Union Canal. Leaving the main waterway we diverted down a shady arm to fetch up in a long deserted basin and wharfage. The children called it the Rat Pool, I believe there was a bone factory there at one time, the rotting stumps of the docking stages the only evidence left of busier times. Hanging my hand over the side of the boat I could trail it through the warming water and more fun still scoop up tadpoles who were browsing on the broad water lily leaves that floated just below the surface.

Beneath the surface we could see water boatmen powerfully swimming to and fro. They have an adapted pair of legs with broadened ends like oars, to breathe some carry bubbles of air and some swim upside down surfacing occasionally to capture a breath. Busy above them cleverly skimming across the surface tension we spied Pond Skaters, Water Crickets and Measurers.

The real treat of this new water level perspective was the Mayflies, not only did they fill the sky in their adult flying form but there on the emerging vegetation we found the discarded skins of the aquatic larvae. Mayfly adults live so briefly, their ditched forms beloved of fish and painstakingly copied by anglers. Mayflies enjoy a long life span beneath the waters but above the un-feeding adults flourish so briefly earning the scientific name of Ephemeroptera. Amongst the emergent Mayflies we encountered Common Blue damselflies, many already joined in a romantic s-shaped breeding embrace clumsily still flying while guaranteeing the next generation’s place in the waterside calvalcade.

Earlier that day we had flushed a Heron lazily into the sky and on the more fly filled stretches were grateful for the work being done by the swooping feeding flight of swallows. A pair of swans hissed protectively as we gave them a wide berth and that evening whilst cycling at Rednal I stopped to take in the rising song of some very loud skylarks. The most exciting bird report over the last month was a Dipper at Weston Rhyn. This delightful chocolate brown and cream bird lives by rivers, foraging up and down it’s home reach. The Dipper has a unique ability to move about, even ‘fly’ underwater while looking for the aquatic invertebrates it feeds on. Dippers have declined in numbers in the UK due to declines in water quality affecting the range of river life available to eat, I do hope that these trends can be reversed. If you would like to set out to see your own Dipper a good start is the bridge parapet at Chirk and the clear waters of the Ceirog.

I am still getting reports of birds in houses, a lucky Blue Tit was carried to safety after entering one local home. Other features of the warmer lighter evenings include good views of feeding bats. We have Pipistrelles and Brown Long eared bats feeding outside the back door and an evening walk around Tedsmore lanes will also be accompanied by bats. Bats can be attracted to the back door by a low light which brings in insect prey and of course a well stocked wildlife friendly garden will also make a welcome feeding station for our most endangered British mammals.

I do hope you too find time to enjoy the summer buzz ,

Happy Wildlife Spotting, yours Pete.
