The Wych Elm

For some time, I've been interested to learn more about our native trees and I've set myself a little challenge to find individual examples and photograph them at different times of the year.

At the beginning of May I observed this tree in the wooded land just over my garden fence. It was still in bud then but has developed nicely during the month (readers should keep in mind that Spring comes later and nature makes a slower start in upland Redesdale). Using Collins Complete Guide to British Trees and Roger Phillips' Trees in Britain as my reference sources, it is clear that this is an Elm tree, I think a Wych Elm (Ulmus glabra).
