In 1986, the second Forest Dynamics Plot was initiated in peninsular Malaysia in a collaboration among the Forest Research Institute Malaysia, the CTFS/Harvard University, and STRI. Since the project's initiation, the National Institute of Environmental Studies of Japan has become a project partner. The plot is located in Pasoh Forest Reserve in lowland dipterocarp forest, a type of evergreen tropical moist forest. The area is aseasonal and has a flat terrain. The first census was completed in 1989, and two recencuses have been completed since then. This plot contains more than 800 species and approximately 340,000 trees. Many of the plot's species are commercially important and are the focus of intensive demographic study. Furthermore, analyses of the human uses of the Pasoh forest and economic valuations of forest resources based on Pasoh FDP data have been conducted.
