Ecology of A Medicinal Tree Strychnos ligustrina Bl, in Dompu District, West Nusa Tenggara Province

ABSTRACT. Strychnos ligustrina Blume is one of the important non timber forest products (NTFPs) for medicinal purposes in Dompu District. Its existence in the natural habitat has been threatened by exploitation of local people. Local people are interested in domesticating the plant, but cultivation technology has not been developed yet. Ecological information is needed to support and guide the development and management of the plant. This study aims to investigate the site characteristics, distribution pattern, stand density, dominance and its association with other species. Nine sample locations had been set up in forest area of the Dompu District. The transect survey was used to determine spatial distribution of S. ligustrina. The environmental variables were measured in each sample location. The line plot sampling method was used for inventory of vegetation. The result shows that the species was distributed in forest area with the altitude of up to 300 m above sea level. The whole range of S. Ligustrina in Dompu District broadly experienced a dry climate with 5-6 of dry months and 1,032 mm of mean annual rainfall. S.ligustrina was able to grow on land that is physically strenuous and very varied soil properties. Stand density of S. ligustrina seedling and sapling were higher than that of pole and tree. Spatial distribution of the plant was clumped, and had a high positive association with Schoutenia ovata and Grewia koordersiana. S. ligustrina was not the most dominant species in its habitat, but conservation effort is needed because of its rarity.
