Analisis Vegetasi Hutan Pamah di Pulau Batanta, Raja Ampat, Papua

Abstract

ABSTRACT
Vegetation Analysis of Lowland Forest in Batanta Island, Raja Ampat, Papua. A vegetation
analysis of Batanta lowland forest has been made by setting up 17 plots of each 30-m x 30-m
distributed in 3 study sites were Yenanas (5 plots), Yensawai (7 plots) and Wailebet (5 plots).
All trees (dbh. e”10 cm) within all of 17 plots were measured, and determined their positions,
and identify their species. In total there were 171 tree species recorded within plots and
belonging to 108 genera and 40 families. Pometia pinnata was the most common species
followed by Anthocephalus macrophyllus, Pangium edule, Toxotrophis illicifolius, and
Koordersiodendron pinnatum. Almost all of common species such as Pometia pinnata,
Anthocephalus macrophyllus, Celtis hidebrandii and Intsia bijuga were observed as the
emergent and/or canopy trees. According to ordination analysis there were five community
types, Aporusa–Pometia, Antocephalus-Toxotrophis, Sterculia-Grewia, Ficus-Antocephalus,
and Duabanga-Pterocymbium communities. However floristic compositions varied among
plot sites, which might be a characteristic of vegetation of Papua and the nearby small islands.
