Padang Sugihan Reserve is one of sanctuary areas in South Sumatra Province becoming the natural habitat of Sumatran elephants. Nowadays, this areal reserve is going through destruction threat because of local society activities staying in surrounding sanctuary area. Illegal logging Maleleuca cajuputi and annual fire of vegetation in dry season have changed the vegetation structure in preserve area. Deforestation has affected on micro climate, decreased the supply of elephant food plants and reduced elephant home range. The vegetation destruction can minimize the elephant reproduction hatchability so that it can threat elephant conservation. This study aims to inventory the vegetation species involving species of elephant food plants in five community types growing in reserve area that is mixed swamp forest in along the edge of Padang river, community of secondary forest growing along several primary channels, Malaleuca cajuputi community, land grass community and swamp grass community along Sugihan river. The vegetation analysis had been conducted by using line transect method in square plots sizing 20 x 20 m (trees), 10 x 10 (stands), 5 x 5 m, 2 x 2 m (seeds), 1 x 1 (herbs and grasses). The results showed that there were 48 species of plants in mixed swamp forest and secondary forest that are 27 species as seeds till trees and 17 species as herb vegetation and 4 species as small plant. Mentaru (Schima walichii), Putat (Barringtonia spicata), Pelangas (Antidesma tetrandum), Leban (Vitex repens) as trees and stands, and Lempuar (Achasma megalocheilas), pakis (Nephrolepis exalata) as herb vegetation were the general species found in both communities. Plant species as elephant foods consisted of 14 species (seeds till trees) and 17 species as herbs. Malaleuca cajuputi was the dominant trees in this community type and almost there were none of another tree species. Herb vegetations were dominated by Belidang (Fimbristylis annua) and Ilalang (Imperata cylindrica). In the type of land grass and swamp grass communities, it was found 10 species that is almost all of them as elephant food plants, in which Belidang, Ilalang and Pakis Resam (Gleichenia linearis) dominated land grass communities and Kumpai Minyak (Paspalumconjugatum), Paspalum virgatum, kumpai tembaga (Paspalum fasciculatum) dominate the communities of swamp grasses
