Mahogany ranks as one of the world's finest timbers and it will probably be commercially extinct by 1990. The dramatic decrease in trade of true mahogany as well as a switch to previously untapped resources since the early 1970s reflects a general pattern of over-exploitation of tropical rainforests. The lack of mahogany cultivation and a move into other, unrelated mahoganylike, primary rain forest hardwoods, such as meranti and red lauan, emphasises an inevitable and irreversible decline for many hardwood forests. The authors give a summary of historical and current trade patterns in mahogany as part of a pilot study initiated and sponsored by ffPS in 1982.
