Dendang B, Handayani W. 2015. Structure and composition of forest stands in Mount Gede Pangrango National Park, West Java. Pros Sem Nas Masy Biodiv Indon 1: 691-695. The Mount Gede Pangrango National Park is one of the biosphere reserves in Indonesia, for the protection of life support system, preservation of biodiversity and ecosystems, as well as the sustainable use of natural resources and ecosystems. Continuity of these functions is determined by the presence of vegetation and required the management system based on the analysis of vegetation. The research objective was to determine the structure and composition of vegetation, especially trees, in a part of the Mount Gede Pangrango National Park. This study used quadratic plot, with a transect length of 100 m and 20x20 m2 plot for observation of trees stage, 10x10 m2 plot for poles, 5x5 m2 plot for saplings and 2x2 m2 plot for seedlings. The results were analyzed using Importance Value Index, diversity index of Shannon-Wiener, Shannon uniformity index and dominance index. The survey results known there were 25 species of trees at various growth stages. The upper strata of stands were dominated by Altingia excelsa. Most of the trees have a diameter class from 10 to 35 cm) found in most of A. excelsa (35 trees/ha). Altingia excelsa (IVI=127.8%) were the dominant species at the trees stage, Villebrunea rubescens (IVI=116.3%) at the poles stage, Laportea stimulant (IVI=34.7%) at the saplings stage and Cestrum aurantiacum (IVI=73.8%) at the seedlings stage. Polyosma integrifolia have a regeneration prospect positively, with numbers of seedlings and saplings dominate the structure of vegetation growth. Diversity index (H ') of trees at each growth stages were nearly steady (0.765 to 0.901). Dominance index (C) of trees at each growth stages was low (0.128 to 0.214). These dominance index values indicated the dominance ability of each species in the community was balanced relatively, thus the diversity preservation can be maintained. Uniformity index (e) of trees at each of growth stages was low (0.372 to 0.432), showed the high species composition.
