Never noticed anything different about the tree they've felled, so the question now is what was wrong with this tree, and are the other oaks, along South Vale and trees elsewhere in Harrow, in danger now as well? It's been reported from other areas of the country that privatised contractors are felling trees and replacing them with saplings, because it's cheaper than maintaining the old trees. Could that be happening in Harrow?
