| Abstract | ||
| We examined structure, diversity and importance value index (IVI) of tree species in dry forests of Binafun, Bonmuti, Letkole and Oelbanu, Mutis Timau Conservation Forest Management Unit, East Nusa Tenggara province, Indonesia. To obtain data on the composition and diversity of vegetation carried out through the analysis of tree species using sampling plots in a rectangular shape, with a size of 100 m x 100 m at 100 m intervals. Results of tree species list showed that there were 94 species belong to 45 families and 72 genera. Tree species richness ranged from 1.81 to 10.06, tree density about 166 individual/ha-545 individuals/ha and basal area ranged from 5.78 m2/ha to 27.79 m2/ha. Eucalyptus urophylla was the most abundant tree in the research sites (except Letkole) and well distributed. Species richness, density, Shannon–Wiener index and basal area are important factors in determining the tree species diversity in research sites. The results in this research should be useful to the dry forest management and conservation managers and researchers. | ||
