Landscape Characteristics on Forest Health Measurement Plots in Several Forest Functions

Abstract

Abstract The assessment of tree damage aims to measure the level of tree damage so that the tree damage assessment can measure the level of disturbance to trees so that they can know the condition of the forest and know what happens in the future. This study aims to determine the landscape characteristics in the cluster of health measurement plots in three forest functions (production forest, conservation forest, and protection forest). The stand damage index for the cluster plots was collected, and perform spatial analysis, which included stand damage in the cluster plots based on landscape characteristics (road distance, slope, and elevation). The tendency of damage due to reach from the road tends to damage other stands. Significant damage occurred in conservation forest rather than protection forest and production forest with a percentage value of 98%. Slopes have a reasonably substantial damage effect-the higher the hill, the more damage to the stand. The gradient of 25-40% (steep) has a significant impact on protected forests with a percentage of 85%. Altitude does not matter much where low height causes considerable damage-substantial damage to production forests <500 masl.
