Abstract

Three slopes of 100 m long are defined in young secondary forest with gentle and slightly steep slopes. In each part of the slope, we built 1 (one) PUP of 20m x 20m which is consisted of 3 (three) Sub PUPs of 10m x 10m to represent the density of sparse, medium and dense understorey and 1m x 1m of sub-PUPs for litter harvesting. A total of 18 (eighteen) PUPs, each 54 (fifty four) Sub PUPs and Sub sub PUPs were made in this study. The HPFU area is dominated by young secondary forest coverage with gentle and slightly steep slopes. The C reserves of herbaceous understorey is greater than that of woody plants. C reserves of all components studied in the gently sloping area are greater than the steep ones. The largest C reserves is found in leaf litter for all slope positions except for a slightly steep lower slope, the largest C reserves is found in finer litter. The total C reserves of understorey and young secondary forest organic litter in HPFU 933.4 tonnes and 95.9% are stored in litter.
