2°58′55″N 102°18′47″E / 2.982°N 102.313°E The Pasoh Forest Reserve, a nature reserve located about 8 km from Simpang Pertang, Malaysia and around 70 km southeast of Kuala Lumpur. It has a total area of 2,450 hectares, with a core area of 600 ha surrounded by a buffer zone. Palm oil plantations surround the reserve on three sides while the other side adjoins a selectively logged dipterocarp forest. An average of 2 metres of rain fall each year, ranging from 1,728 to 3,112 mm.[1] In 1987, a 50 hectare forest dynamics plot was established in the reserve,[2] which began as a collaboration between the Forest Research Institute Malaysia, the Forest Global Earth Observatory (ForestGEO; previously Center for Tropical Forest Science),[3] and the Smithsonian Tropical Research Institute.[4] Three censuses of the tree population in the plot have been carried out, the first in 1989, and have counted about 340,000 trees belonging to 800 species in that plot.[4] The reserve has largely been destroyed by loggers and miners.[citation needed]
