TreeAH (tree assessment for heritage status)

TreeAH is a method of assessing whether trees are sufficiently important to be assigned heritage status. Its purpose is to help tree managers and all others interested in trees to systematically assess the suitability of trees for heritage designation. Its basic principles are common to heritage tree identification around the world and it can be applied internationally, with local modifications.

TreeAH is currently undergoing field testing in a number of countries and Version 7 is published below as a working draft for review and comment until more detailed versions are available.
