Founded in 1988 by dendrologists Alan Mitchell and Victoria Schilling (née Hallett), its success is due to a network of enthusiastic volunteer measurers. The database is an important tool in helping to locate champion trees, protect them, monitor their growth and their success in relation to their surroundings, study the associated wildlife and their historic management, and support work to propagate rare or exceptional specimens. Trees are measured using the American Forest system, whereby a points value is calculated based on the circumference of the trunk, and the height and the average spread of the crown. Anyone can nominate a tree, and most trees are nominated by non-specialists. Nominations are sent to the national register of big trees (or to the state registry in the USA); once a nominations is received, field work begins to confirm the tree’s size before it can be declared a champion.
