The distribution of Genus Hopea in Bukit Bakar Forest Eco Park, Machang, Kelantan

This study was conducted in a tropical rainforest in Bukit Bakar Forest Eco Park, Machang, Kelantan. The objective is to identify species from genus Hopea and to determine the aboveground biomass of genus Hopea with diameter at breast height (dbh) of less than 5 cm in Bukit Bakar Forest Eco Park. From the result of the distribution, the abundance and aboveground biomass of the Hopea spp. were calculated. A total of 5 sampling plots with measurement of 20 m x 20 m have been conducted in the study area. The entire Hopea spp. found in the study plot with diameter at breast height (dbh) of less than 5cm were identified. The abundance and aboveground biomass were also estimated. The total of 46 individuals from genus Hopea with diameter at breast height (dbh) less than 5cm were recorded and 7 species were identified. The Hopea spp. in the study area showed moderate diversity with Shannon Wiener Index, H’ value is 1.90, Shannon Evenness Index 0.95 and Simpson Index value is 0.86. The total aboveground biomass value for Hopea spp. in the study area is 44.90t/ha. The data of this study will update the baseline data information in Bukit Bakar Forest Eco Park Machang, Kelantan. This finding shows that it is important to conserve valuable trees of Hopea spp. for future sustainability.
