Above ground biomass after 39 years logging in Kintap Research Forest, South Kalimantan

Abstract Land degradation causes the fragmentation of forest areas. The can be in form a decrease species diversity and carbon storage an area including logged-over This study aims to obtain stand abundance, basal area, potential above ground biomass that used estimating natural recovery Stand measurements were carried out 3 different areas with distance plot from road as differentiating factor. measurement parameters include tree species, diameter, height smallest diameter being 10 cm. Making plots at each location covering 1 ha observation sub-plot measuring 20 m x (400 m2). Estimation allometric model compiled by Brown, Ketterings, Basuki. results showed reached 190 tones/hectares – 290 tones/hectares. is mostly contributed trees more than Trees cm accounted for 50% total biomass. condition indicates silvicultural technique maintaining remaining stands after felling are very necessary accelerating growth small-diameter so succession occur quickly.
