Very hot, dry summer.
Some or most trees suffering mild drought stress (no wet winter and late, wet spring).

Some or most trees with some depletion in crown density due to loss of dysfunctional leaf due to drought then rain.
22
Survey limitations
Brambles and ivy on trees and around bases restricted access. Removed but painstaking and slow.
23
Brambles, holly and other shrubs and trees restricted visual inspection of crowns and branches, directly by obscuring but also by restricting movement of surveyor around trees.
