Geospatial Analysis and Mapping of the Habitat Suitability of Aquilaria Species in Mt. Hamiguitan Range Wildlife Sanctuary, Davao Oriental, Philippines

Geospatial analysis reveals that precipitation is the most influential factor determining habitat suitability for Aquilaria species, with moderate suitability covering 7,199.09 hectares in Mt. Hamiguitan Range Wildlife Sanctuary. The study identified two species, Aquilaria cumingiana and Aquilaria malaccensis, with varying abundance across elevations ranging from 1,171 to 1,480 meters above sea level. Using Multi-Criteria Decision Analysis (MCDA) with Analytical Hierarchy Process (AHP), researchers mapped suitability layers based on precipitation, elevation, soil type, slope aspect, vegetation cover, and distance to streams. The model achieved an overall accuracy of 94.11%, providing critical insights for conservation efforts in this UNESCO World Heritage Site.
