Peat swamp forest (PSF) is one of the most fragile and sensitive ecosystems that support various plants and animals. A study was conducted in Compartment 7 of Kuala Langat North Peat Swamp Forest, Selangor with the objectives of determining tree species composition and its diversity index. A 1-ha plot of size 500 m x 20 m with 100 subplots, each of size 10 m x 10 m was established. All trees with diameter breast height (dbh) of 5 cm and above were enumerated, measured and identified. Results showed that there were 103 species in 64 genera and 30 families. Euphorbiaceae was found to be the most diverse family with 6 genera and 11 species. The two most abundant species were Nothaphoebe coriacea and Gonystylus bancanus. The value of Shannon species diversity index, H` was 5.61 .a-log series gave a value of 28.54 which fell within the 95% confidence limits of 25.26 to 31.82 with x value of 0.97 (0.9x1.0), indicating that species diversity in this forest is on the higher side. Ten endemic species to Peninsular Malaysia were found here. Of these, Garcinia dumosa (rare) and two uncommon species, Popowia fusca and Vatica lobata were also recorded. Popowia fusca was a new record for Selangor. This forest houses nearly 4% of the total number of tree species found in Peninsular Malaysia. The stand density calculated was 1,025 trees per ha with trees in diameter class (5.0-14.0) cm being the most abundant.
