Abstract

The research was conducted in October 2019 in the Bukit Tangkiling Nature Reserve, Central Kalimantan, aiming to find out the type composition, the community structure, and vegetation diversity. This research method is a survey with combination method and carried out purposively in sampling with total sample plots of 60. The results showed that there were 58 species of plants (6 species unidentified) which included 11 species of understorey, 32 species of seedlings, 32 species of saplings, 31 species of poles, and 38 species of trees. Vegetation at the level of seedlings, saplings, poles, and trees in the Bukit Tangkiling Nature Reserve is dominated by Acacia mangium, while the understorey is dominated by nut grass and thatch. The similarity index of vegetation communities between two locations ranged from 41.860 - 73.684%, while that between growth rates ranged from 32.558 - 7.143%. Plant communities have diversity values (H’), richness values (R), and evenness values (E) ranging from low to moderate. The horizontal stand structure has different exposed diameters, forming an inverted “J” curve and is concentrated in diameter class 1019.99 cm, while vertically the individual population is concentrated in high class 5 - 9.99 m.Keywords: Composition, Heterogeneity, Similarity, Stand structure

Abstract

Landfire is one of the main factors of peat forest degradation. This work aims to look for species composition, vegetation structure, and post-fire species diversity. This research is situated in a peat forest area at an administrative zone of Desa Tumbang Bulan, around Sebangau National Park of Central Kalimantan being burned in 2015. The research is conducted using a quadratic plot. The observed parameter includes the species composition of stand structure and its ecology characteristics, i.e. Diversity Index, Richness Index, Evenness Index, and Similarity Index. The result showed the vegetation species in the research site are 101 species classified into 52 families which spread in many levels, i.e. seedling, sapling, pole, tree, and bottom plant. Pandanus sp. and Combretocarpus rotundatus are among the species of tree and bottom plant habitat with the highest NPJ. The index diversity, species richness, and evenness of this habitat range from low to high index value, while the inter-site and inter-growth levels of community similarity are low in general. The horizontal stand structure in the research site had a different exposed diameter that resembles the upside down of the "J" curve and concentrated on 10-<20 cm class diameter.
