Vegetation Structure and Composition on Rafflesia zollingeriana Habitat in Meru Betiri National Park

Abstract

Meru Betiri National Park (TNMB) has five forest formation, e.g. coastal forest, mangrove forest, swamp forest, rheophyte, and lowland rain forest. The study aims to analyze vegetation structure and composition on Rafflesia zollingeriana habitat and to map the distribution of trees in TNMB. Vegetation data, diameter at breast height, and canopy height obtained by using line-transect method and analyzed using vegetation analysis. The sampling method used purposive sampling. TNMB had 64 trees species with 1,366 seedlings and saplings, 257 poles, and 183 trees. Pancal kidang (Aglaia variegata) had the highest Important Value Index (IVI) amounting to 32.46%. The result showed that the community similarity index (IS) in two sample plots was 86.86%. Tetrastigma spp. is a liana as a host of Rafflesia zollingeriana, and only found pancal kidang, besuleh, welangan, magnolia flower, laban, and rauh trees.
