| dc.description.abstract | Shorea platyclados is categorized in critical status which is characterized by a population decline of at least 50% in the last ten years. S. platyclados (meranti bukit) is a commercially important woody tree species in Southeast Asia. This research was conducted to create a distribution map of the mother tree of S. platyclados and a description of its morphology, identify the distribution pattern of S. platyclados, and identify the population structure of S. platyclados in CA Martelu Purba. Field data collection was carried out using vegetation analysis techniques in the form of a combination of plotted lines and lines. Create coordinate points using the Global Positioning System (GPS) and record the morphological characteristics (canopy condition, stem straightness, stem roundness, and branch corner) of each stand of S. platyclados found at the location of the vegetation analysis. Analyze plant population structure based on plant density. Calculating the pattern of spread using a standardized mortality index. Based on the results of field observations, the presence of S. platyclados mother trees was spread fairly evenly in CA Martelu Purba with a total of 339 trees, the average morphological condition of S. platyclados was in good health and condition. Most of the tree canopy conditions were in canopy class 5, then the straightness value of the highest stem was assessed at 100%, the roundness of the stem was also still a lot in a round state. The most branching angles were in the group >70o. The distribution pattern of S. platyclados on seedlings and trees was uniform with Ip values of -0.16 and -0.53, at the sapling the distribution pattern was random with Ip = 0 and the poles were clustered with Ip = 0.02. Population structure of S. platyclados in CA Martelu Purba, showing an inverted J shape, indicating good regeneration. | en_US |
