Pruning, Habitat and Utilities

[treeseer]

Speaking of coronet pruning, a utility company in Australia uses a VTA program that places a value on wildlife habitat. It's company policy to NEVER remove a hollow, for instance--they accept the risk. Compromised trees with basal decay >33% are commonly managed with 10-30% reduction.

 

This is different from the Defect = Hazard = Removal mentality that used to guide utility tree management in the US. I'm wondering what role wildlife habitat has in UK utility tree management--any coronet cuts on trees near wires over there?
