This tree which think is an Ash is definitely diseased and over the past few years has got worst with branches just dropping off periodically. It is situated right by a parking area for residents in a cul de sac at the top of a grass bank. The Cul de sac is in Blackmore Drive with houses 11 - 49. This has been reported before by this means and also phone, a few years ago and we have had no answer , nor has any work been done on the tree. Very concerned as such a large tree.
