Hi to all Tree Surveyors!
20/11 Update: We are nearing completion of the tree survey but there are loads of gaps and dodgy identifications that we need to revisit especially with some of the conifers. In the new year it may be a good idea to have another get together e.g. at Kings Heath Park House and look at our results – what do you think?
Last week we recorded some interesting varieties of the native holly Ilex aquifolium. Round shaped or pyramidal, without prickles, with narrow or wide leaves and often with peculiar pimples on the bark (see pic attached). Slightly distracted by a rabbit being taken for a walk on a lead and a knife stuck into the ground by a tree (subsequently taken to the police station), we measured a lime with enormous leaves and oblique base that may be an American Lime.
The black spots on sycamore leaves are tar spot fungus Rhytisma acerinum (see pic attached) and are not related to black spot on roses.
12/11 Update: We had a productive mornings survey last week and raced around measuring hollies, planes, copper beeches, oaks, yews, mystery little plum like trees laden with lichens. A mystery lime had jagged leaves, some with 3 points rather than the usual heart shaped leaves and the plane trees seemed to be of two kinds – we need to study the books before all the leaves disappear!
The autumn colours are stunning at the moment – russet oaks and glowing beeches.
3/11 Update: At our last survey, we managed to cover the area next to the rose garden and continue with the trees near the allotments. It was cold and windy but in spite of freezing fingers we reached the 500th tree of the survey – an ash with the remains of an old nestbox (does anyone know when these were put in?) and with a girth of 234 cm. We also found oak, beech, hornbeam, yew and an old little tree that may have been a crab apple or a plum. We may also have found a midland hawthorn but this needs confirmation. Some interesting slabs of stone with two notches in each were arranged around a sycamore. I have emailed the picture of them (see attachment) to Phillada, the historian. She thinks they may have been part of the greenhouses that used to be part of the Henburys estate and used to be on the eastern edge of the rose garden but she did not know why there should be two notches. Does anyone else have any ideas?
All the best Ellen
PS apologies for not sending an update on our last October survey – we did very well and recorded 13 tree species in a small area once part of the Henburys estate. These included possible Sawara cypress, large leaved lime and hornbeam as well as a Golden Fastigiate Yew along with other yew trees.
