[摘要] Mahagony (Swietenia macrophylla) is an important tree in USU campus as greenline and education forest and as much as 1054 trees were found here. The method of Forest Health Monitoring (FHM) is one of the ways to assess the health status of the tree. The objective of this research was to evaluate the health status of mahagony trees in the USU campus area. 1054 trees were evaluated for their health using FHM Methods. FHM method was applicated through a series of tree damage observation. This study showed that 9 types of damage were found in this research, those were cancer (0,47%), konk or decayed further (1,99%), open wound (0,37%), brum (0,66%), broken and dead branches (25,33%), brum in canopy (0,75), crown dieback (0,75%) and leaves damage (25,33%). Result showed that 372 tree (35,29%) was in healthy condition, while 531 tree (50,34%) was in moderate damage and 148 tree (14,07%) was in serious damage. Based on the Level Damage Index, most of the health status of mahagony trees in USU campus was moderate, it indicated that maintenance activities were required to prevent greater damaged.
