Species Richness and Composition of Vegetation in Logged Over ForestPT. BFI SOTEK, East Kalimantan

ABSTRACT

Forest degradation due to timber harvesting generates ecological changing including biodiversity. This study investigated the impact of logging activities on species richness and composition of vegetation. Heavily degraded forest (recently logged, all commercial trees at dbh of >40 cm were cut), lightly degraded forest (old degraded forest, ready for the next cuting cycle), and nearby protected forest (as control) were sampled. Result showed that species richness in the heavily degraded forest is lowest in all size classes. The lightly degraded forest has the highest species richness in the seedlings, saplings and trees size classes. While the highest species richness of the poles was in the protected forest. Species density of saplings and trees were highest in the protected forest, seedlings were in the heavily degraded forest and poles were in the lightly degraded forest. Dipterocarps species as commercial timber has highest composition in the heavily degraded forest forest in seedlings and poles classes. Dipterocarps species composition of saplings was highest in the protected forest and trees were in the lightly degraded forest. The lightly degraded forest and protected forest have the most in common species. Vegetation assesment in logged over forest should be carried out periodically to verify the impact and determine the appropriate management intervention to support forest sustainability.
