Daftar Isi:
  • Kabesak (Acacia leucophloea) is a particular plant species and recognized to have important benefits to the local people of Timor Island. The people of Timor Island use kabesak leaves as animal feed in the dry season and kabesak wood is used as building materials and furniture. The purpose of this study was to determine the stand and site characteristics of kabesak in the western region of Timor, Indonesia. The means of density, frequency, dominance, and importance value index were analyzed. The results showed kabesak stand structure in secondary forest land, grassland, and shrubs, as well as garden showed the J-inverted shaped, which implies that natural regeneration was a proper continuation. Kabesak had significant associations with a few plants’ species, both negative and positive types. The result of regression analysis of the principal components showed that the contribution of edaphic factor influences the population density of kabesak. Silt fraction and phosphorus content were found to have the highest positive effect on the density, while sand fraction and sodium content were found to have the highest negative effects of kabesak. A test for altitude with Tukey test (α = 0.05) reveals that kabesak from 0-300 m a.s.l., 300-600 m. asl., 600-900 m a.s.l. were not different from each other, while altitude >900 m a.s.l. was significantly different from the other groups.
