Although Myanmar exports millions of dollars of rattan cane each year, the last systematic treatment of rattans in this country was done over 100 years ago, and virtually nothing has been writ- ten about the collection and trade of this important forest resource. Here we report the re- sults from a study of rattans in the Hukaung Valley Tiger Reserve in northern Myanmar. A total of 15 species of rattan were encountered; seven species are new records for Myanmar and two species are new to science. Inventory transects revealed that the density of com- mercial rattans in local forests averages 40.5 canes ≥ 4 m long/hectare. Populations of all species appear to be actively regenerating. The current pattern of rattan exploitation, how- ever, is largely uncontrolled and will eventually lead to resource depletion unless some form of management is implemented. Key Words: Myanmar, Hukaung Valley, rattan, sustainable harvesting, non-timber forest products. Rattans are spiny climbing palms native to the Of special interest in this regard is Myanmar.
