Cushion fungus

The cushion fungus (Phellinus pomaceus) usually occurs on the branches of cherry or plum trees, wild and cultivated.  I found this one on a dead branch of cherry in the old tree nursery near post 16 in Filnore Woods. 

It gets into the tree via a wound of some sort, and makes the branch brittle so that it may snap off.  Not so good, you may think but on the other hand it does a good job of clearing up dead cherry and plum trees.

Hedgehogs

Did you cook a hedgehog accidentally on bonfire night?

A typical bonfire heap of sticks and twigs and autumn leaves is just what hedgehogs are looking for for their winter hibernation place or 'hibernaculum'.  So it's a good idea to either build the bonfire immediately before you set light to it, or look underneath.

Alternatively, build a heap of sticks and leaves specifically as a hedgehog hibernaculum.

I haven't seen a hedgehog in Thornbury for about 30 years, but one of our volunteers, Paul, says he has seen them in his garden recently.  Their population is in steep decline nationally, plummetting from an estimated 30 million in the 1950s to only 1.5 million now.

Nobody is sure why but it could be any or all of these:

(a) loss of hedgerows and permanent grassland - at Filnore we are trying to reverse the trend in a small way

(b) less prey - slugs, snails, earthworms, centipedes, millipedes, etc - because of pesticides

(c) smaller, tidier gardens with fences, which makes it harder to move around and find food 

(d) habitat carved up by new roads and buildings isolates small populations of hogs, which makes them more vulnerable to local extinction.

Apparently they are good swimmers, but can get stuck in garden ponds if it's hard to climb out.

Nov 21st  is The Day of the Hedgehog.  The People's Trust for Endangered Species is holding its annual conference for hedgehogs in Telford - I mean about hedgehogs.


Here's a link to Avon Wildlife Trust's hedgehog booklet - how to build hoghouses, how to feed hogs, how to make your garden hog-friendly.

Frilly Fern

At Filnore Woods we have a lot of Hart's Tongue Fern (Asplenium scolopendrium).  It has flat undivided leaves with slightly wavy edges.  I should say 'fronds' for a fern -  they're not strictly leaves from a botanical point of view.  It's the only British fern with undivided fronds.

A hart is a male red deer and the specific name 'scolopendrium' according to wikipedia, is the latin word for centipede.  This is because the brown spore cases on the back of the leaves once reminded somebody of centipede's legs.

Hart's tongue is a woodland fern and prefers alkaline or limey soils, or rocks including walls.  So if you see it you can be fairly confident the soil is over limestone and therefore alkaline. 

But in the photo below, this particular specimen, growing in the old tree nursery, has extraordinarily frilly fronds.

Oh the wondrous variety of nature!

Apples and Pears

In the tunnel of the old Northavon tree nursery we have a number of unusual trees including crab apples, which have now shed their fruit. 

 It won't be wasted:  birds, small mammals and the last of the insects will relish this feast.

And up near the memorial limes at post 3, the wild pear trees we planted seventeen years ago are also fruiting

Not very tasty for humans but another feast for the inhabitants of Filnore Woods.

Wondrous dewy webs in the autumn sunshine

Not always easy to spot because of their habit of hiding under leaves, many spider species are at their peak.  Many of the males will have died from exhaustion (you know how it is) but females will be preparing to lay their eggs in a cocoon of silk to overwinter, and hatch into spiderlings in the spring - as orphans, sadly. 

Webs show up well on misty mornings when the dew clings to them.

Quite often the Garden Cross Spider will sit in the centre of her web, waiting for an insect to fly into the trap.

Until the killer frosts come.  

Goodbye, spiders, until next year.

Mellow yellow

Just couldn't resist snapping this young aspen in its autumn plumage.

And the cherry near post 2 has also laid a startlingly yellow carpet of leaves.

Actually it's not strictly 'post' 2;  the number is painted on the cherry tree.

While I was snapping, the breeze released a fresh fall of leaves.  Unfortunately my camera was not fast enough to freeze them clearly in mid-flight but that's what the yellow blobs are in this last photo.
