ABSTRACT

The Soraya Research Station is a critical forest research conservation area in Aceh Province. The forest area consists of essential and valuable tree species, including Dipterocarpaceae. This research aimed to determine the population structure and regeneration status of trees at the Soraya Research Station. The vegetation analysis was used for this purpose. The total height of each tree and the diameter at breast height (DBH) were also collected for population structure analysis. According to the research findings, the vertical stand structure in Soraya Research Station is dominated by stratum C, which is in good condition and forms an inverted J shape, with a decrease in the number of individuals as the DBH size increases. A total of 126 tree species with varying regeneration states were found. As much 40.47% (51 species) have new regeneration, 46.03% (58 species) have poor regeneration, 1.58% (2 species) have good status, 8.73% (11 species) have none status, and 3,17% (4 species) have fair regeneration. According to the findings, conservation efforts were urgently needed in this location due to regeneration problems.
