Following the increased protection for ancient and veteran trees in NPPF 2.0, Sylvan co-Principal Julian Forbes-Laird has designed and now makes freely available RAVEN: the definitive guide to Recognition of Ancient, Veteran & Notable Trees.
Based on widely accepted attributes published and promoted by the Ancient Tree Forum, RAVEN provides a simple and rapid tool for standard assessment of trees against recognised criteria. RAVEN rests on the presence or absence of determinative features, set within a process designed to reduce false positives whilst ensuring that genuine veteran (and ancient) trees are correctly identified.
RAVEN is free to use though JFL requires users to retain the copyright tag.
