Richard Bell's nature sketchbook since 1998
A micro-hike around the arboretum and conifer plantations at Newmillerdam this morning. I got a surprise when I saw a tiny invertebrate trundling by as I focussed on algae on a tree trunk. I couldn’t see it at all with the naked eye but it no doubt ran for cover from the glaring light of the eight LEDs of my mobile microscope.
Flaky bark and even flakier tree recognition: I take a closer look at the tree that I photographed on Friday and, although the bark is flaky, it isn’t as flaky as that of London Plane: it’s Horse Chestnut, which probably explains why the bark is so polished; it’s been climbed by generations of conker collectors.
At this time of year, the swelling buds are almost as distinctive at the autumn conker fruits. The bud scales are red-brown and sticky and beneath them are the shield-shaped scars where last year’s leaves were attached.
The lenticels that dot the twigs are raised pores which allow for gaseous exchange.
