Natural forest dynamics. I. Homogeneity of species distribution
This study was carried out on a randomly chosen 10-ha (200 × 500 m) forest area within the 50-ha Demography Project area of the Forest Research Institute Malaysia (FRIM) in Pasoh Forest Reserve, Negri Sembilan, Malaysia. The 10-ha study area contained 13 950 trees of 5 cm dbh and larger with a total...
