Proposed Actions

UKBAP Signposting Actions:

1. Maintain ancient tree resource - ensure there will be continuity in age structure, without losing well lit bark habitat on veteran Oaks.
2. Nutrient deposition is a problem, since it requires acid bark (sic).  Action should be to reduce this in any area containing ancient trees - many but not all of these will be in the priority habitat.
