Borneo's rain forests are also home to some extremely rare species of orchids, all highly valued for their exotic aromas and aesthetic beauty. Borneo's orchids are also endangered, a result of the loss of natural habitat from fire, forest damage, and illegal logging. Increased exploitation of the forests of West Borneo, including gold mining and illegal burning, has led to the certain extinction of hundreds of orchid species.
