The purposes of this research were to evaluate the potency, habitat physics condition and distribution of pasak burni (Eurycoma longifolia Jack) on natural forest in Orangutan Research Centre Gunung Leuser National Park North Sumstora. The location of this research was situated in the elevation of 100 - 500 m ou above ses level with surging topography.
'The results of this research indicates that the highest population of pasak buri (Burycoma longifolia lack) was in seedling phase, with density value was 8.4 individual/ba and frequency value was 0.206. Population density highest found in the elevation of 200 - 204 m on above sea level (0.006 individual/m) Distribution pattern of pasak bumi (Eurycoma longiolia Jack) was in grouping
pattern. This be showed by the value o' (10.42) = & (20.6). The significant test
