Hundreds of knopper galls are scattered beneath the oaks in Nostell Park. On some you can see the way that the acorn has been transformed into the home and the food source for the larva of the gall wasp Andricus quercuscalis. The acorns have stalks, botanically penduncles, so these are the acorns of the common or pendunculate oak, Quercus robur.
It’s the asexual generation of this gall wasp that produces the knopper gall; the alternate sexual generation produces tiny galls on the male catkins of the Turkey oak, Quercus cerris. Turkey oak acorns have ‘mossy’ cups, that remind me of the furry Russian hat that Ivan the Terrible might have worn. There are several Turkey oaks at Nostell.
This species of bracket fungus is sprouting on deciduous stumps in the woods around the lakes.
Rabbit Mesh
The head gardener is adding wire mesh to the newly restored iron gate to the walled garden.
“Is that to stop the ducks getting in?” (It’s been a good year for the mallards on the nearby lakes).
“No, rabbits.”
“I worked on the film of Watership Down, so I’m always rooting for the rabbits.”
“There’s plenty of grass out there!”
