This is on Laundress Green in Cambridge. They are cutting the trees back for the health of the people in the community. ‘Health and Safety’ regulations make the Council responsible for any damage the trees might do to people on public land.
And here you can see the danger against which they are guarding, all over Cambridge. Here is an example of a willow that gave up the ghost and cracked and broke.
It may be a Crack Willow. Perhaps next time I am near it I will take a guide and try to discover what exact species it is. Apparently in Britain, the most common are the White Willow (Salix alba), the Crack Willow (Salix fragilis) and the Osier (Salix viminalis). Look at the very informative Latin name of the Crack Willow… So that may be where I will start to learn a bit more.
I have always been confused by the Willow species, and especially because of Osiers and Sallows, and how some have broader leaves and some have whiter or blue-white leaves… and on and on with all that knowledge to be acquired.
