I have been in love with nature as long as I can remember. Nature photography, birdwatching, lichens, fossils, orchids, mountains, insects, everything else. Conservation, gardening at home, community gardening. I've loved it all.

Scything the Gunnersbury Triangle Ramp

Scything and raking the ramp meadow. An Evening Primrose, still in flower on 23 October, has been left. The wooden rail has been replaced by a linear loggery of Birch and Willow posts, providing habitat for insects and fungi.
This Bank Vole nest was exposed by the mowing. The vole itself could be seen wriggling through the remaining grass and leaves, and we all had a brief but good view of it as it emerged, chunky dark brown body, short tail, and slow progress very unlike a woodmouse.
The next day … we saw this Bank Vole eating Mugwort seeds in the wildflower area with the apple tree, next to the tool hut.

Fantastic Fungus Foray at Gunnersbury Triangle!

Alick Henrici telling a few of the GT group about Fly Agaric (Amanita muscaria).
Boletus erythopus, a large brown mushroom and relative of the Cep, blue-staining when freshly cut. The colour is unprocessed , it really was that blue. Also called “Scarletina Bolete” and B. luridiformis.
All right, here you are. Amanita muscaria in all its glory

It was a beautifully sunny and warm late October day, and Alick was pessimistic. It had been far too dry for weeks and there would be very few fungi on the walk. But he admitted that children were very good at spotting mushrooms.

They were. We found 31 species,  more if you count the small Ascomycetes of the kinds whose fruiting bodies are little dots on rotting twigs.  Some indeed like the Fly Agaric and the Scarletina Bolete were large, colourful, and spectacular; others smaller and quieter, but often also beautiful, and all fascinating. None were stranger than Crepidotus mollis, the Peeling Oysterling, a bracket-shaped gill mushroom with a peeling cuticle, and an extraordinary jelly-like consistency revealed by gently stretching the cap, as shown in the photo.

Crepidotus mollis, a smooth thin cap with jelly-layer when stretched, found on path-edge log

Alick Henrici writes that he found four species new to the reserve during the Fungus Foray:

  1. Clitocybe phaeophthalma (aka C. hydrogramma); “nasty smell”
  2. Mycena crocata; “old specimen, unexpected but colours unmistakeable”
  3. Panellus stipticus; “a common late season species on wood”
  4. Pleurotus dryinus; “on Elder at post 6, not very common but often on this host”

Helen Wallis We’ll Miss You!

Helen Wallis on Frog Day a few years ago in Gunnersbury Triangle

Helen has worked for London Wildlife Trust for ten years, several of them as volunteer officer at Gunnersbury Triangle. She did the job with enormous energy and enthusiasm, and got the best out of everybody. Her frog day was memorable not just for her stripy green face but for the improv frog puppet show conducted behind the gate to the wheelbarrow store!

In her farewell interview for Wild London, she said “We also had amazing older volunteers who could turn their hand to anything” (thanks!) … “I really enjoyed working with them [of all types], because they taught me so much – we had volunteers who were experts in everything from butterflies, birds, and amphibians, through to the military application of animal camouflage” (thanks Helen, I know who that is!) … “Plus, I was always amazed at the sheer volume of practical management work they could get done.” (We know, we know.)

Helen, have a great time in your new job at Greenwich. We’ll miss you.

Lunar Underwing Moth in Gunnersbury Triangle

Lunar Underwing Moth from among the grassy tussocks in the Small Meadow

We carried on clearing brambles from the north bank and then the small meadow. The debrambling of previous years has helped, as there are far fewer large deep-rooted monsters than before, but we’ve still had plenty to do. I coppiced some Holm Oak, too.

We saw two or three of these Lunar Underwing moths (Omphaloscelis lunosa) among the grass. They eat grasses such as Yorkshire Fog and Annual Meadow-Grass.

Autumn Insects at Thursley Common

Black Darter – a dragonfly in late September, and a windy day too. The only other dragonfly about was the Common Darter, I saw two or three.
Woolly Bear caterpillar (of a Garden Tiger Moth) on one of the boardwalks.

Other insects seen included a few bumblebees and some moths scooting away in the strong wind, perhaps Silver Y.

There were only a few birds about; I saw some swallows, two stonechats, a crow, a jay, a gull, a chaffinch, and a finch-sized bird with a white rump flying into a tree, perhaps a bullfinch. Three mallard loitered on the Moat Pond.

A flash of yellow revealed some Gorse in bloom, alongside some fine purple Bell Heather.

The only fungus to be seen was a brown rollrim. A dead birch trunk was colourful with Common Orange Lichen.
