Assessment of Forest Health Using Biodiversity and Productivity Indicators in Gunung Sasak, West Lombok

The community forest of Mount Sasak plays a pivotal role in maintaining ecological functions while supporting community-based forest management. This study aims to assess forest health conditions in the Mount Sasak community forest, West Lombok Regency, using the Forest Health Monitoring (FHM) approach. The research was conducted from November 2024 to January 2025 in an area of approximately 477 hectares, with a sampling intensity of 1%, resulting in 12 cluster plots. Forest health assessment was based on two ecological indicators: biodiversity and productivity, measured using the Shannon–Wiener diversity index and basal area, respectively. The results indicate that the final forest health scores (FFHS) across cluster plots ranged from good to poor conditions. Overall, the forest health status of the Mount Sasak community forest was classified as moderate, with an average FFHS value of 2.65. These findings suggest that although certain areas exhibit favorable ecological conditions, more targeted and sustainable management efforts are required to maintain and improve forest health.
