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.|
