Abstract : Woody climbers play an important role in overall plant diversity and carbon storage in a tropical forest. This study aimed at investigating woody climbers in tropical evergreen forests, in southern Vietnam. Forty-four survey plots of 2,500 m2 each were used for field data collection in four forest types experiencing different disturbances as rich (standing volume/SV>200 m3/ha), medium (100<SV≤200 m3/ha, poor (50<SV≤100 m3/ha), and very poor (10<SV≤50 m3/ha) forests. Twenty-six woody climbers were recorded with 17 species in rich, 20 in medium, 10 in poor, and 13 in very poor forests. Two species that appeared in poor and very poor forests are missing in rich and medium forests. The diversity Shannon–Weiner index (H’) and evenness (J) indices are in the order of reducing from rich forest (H’=2.37, J=0.83) to very poor forest (H’=0.92, J=0.57). Stem density and aboveground biomass (AGB) of woody climbers were significantly different among four forest types; 876 stems/ha in the rich forest, 1,246 stems/ha in the medium forest, 785 stems/ha in the poor forest, and 1,991 stems/ha in the very poor forest; AGB was 5,570 kg/ha in the rich forest, 9,444 kg/ha in the medium forest, 3,573 kg/ha in the poor forest, and 20,560 kg/ha in the very poor forest. It is concluded that previous disturbances significantly changed the diversity and structure of woody climbers by reducing diversity but increasing stem density and AGB in the forest with higher intensity of disturbance.
