TREE AND LIANA ENUMERATION AND DIVERSITY ON A ONE-HECTARE PLOT IN PAPUA-NEW-GUINEA

Enumeration of a one hectare plot at 900 m a.s.l. in Papua New Guinea revealed 693 individuals of 228 tree and liana species greater than or equal to 10 cm DBH. A 0.1 hectare subplot contained 302 individuals o f 106 species 2.5 less than or equal to DBH < 10 cm. Lauraceae, Morace ae, and Myristicaceae were the most important families in both size cl asses. This site is very diverse compared with other tropical forests, and like other species-rich sires worldwide, it has high a seasonal r ainfall and high rates of natural disturbance.
