Abstract : A comprehensive assessment to determine species composition of a logged-over dipterocarp forest in Kahupian, Sogod, Southern Leyte was conducted as contribution in documenting vegetation in remaining dipterocarp forest patches of the Philippines. The species composition was described by way of Braun-Blanquet (1964) methodology. The study had three sampling sites. Ten plots per sites were taken, at plot size of 20m x 20m and total area of sampled stands of 1.2ha. A total of 154 species, in 60 families and 104 genera, were recorded in the inventory. Of these, 131 are tree species and 23 are non-tree. The 131 tree species belong to 44 families and 84 genera. The 23 non-tree species were in 17 families and 22 genera. The highly represented tree families were the Dipterocarpaceae, with 13 species. Tanguile (Shorea polysperma), mayapis (Shorea palosapis) and white lauan (Shorea contorta) were the most frequently dominating and widespread within the site. The Jaccard similarity index in comparing the 3 sampling sites was 0.39 to 0.44, which indicated less than half of the species occurred commonly in any two sites. This suggests high variation in species composition from site to site and that intensive and extensive data collection is needed before a final assessment on floral diversity in Southern Leyte should be attempted.
