Trends, long term survival and ecological values of hedgerow trees: development of populations models to inform strategy.
Defra project BD2111
The main objective for the study has been to develop a population model for isolated hedgerow trees in order to review, and if necessary amend, the 2006 HAP targets for hedgerow trees, in particular the number of young trees required to ensure that the isolated hedgerow tree population remains stable or increases. The second main objective was to collate and review existing information on the biodiversity value of hedgerow treeswith emphasis on invertebrates, comparing where possible the role of isolated hedgerow trees and lines of trees.
