AB Damar agroforests are multi-species, multistrata agroforestry systems made up of a mosaic of individually owned and managed plantations in Indonesia. Damar (Shorea javanica) is the main species used for resin as well as timber. Other species include fruit trees, leguminous trees and other trees which are left to regenerate naturally as long as they do not compete with the economic trees. The functional ecology and optimal management of such complex agrororest is not well known. This paper gives a first account of long-term measurements that have been carried out for six years. The following regressors were used to predict yearly girth increment: crown position, crown form, species group, initial girth and competition index.
