| Abstract: | This research aimed to evaluate elephant habitat conditions in the Sai Yok National Park, Thailand, using high-resolution Pléiades imagery and InVEST Model's Habitat Quality Assessment (HQA) model. Land use was also analyzed as an input in the model using feature selection via the Grey-Level Co-occurrence Matrix (GLCM) and classification using the Random Forest (RF) algorithm. The risk and vulnerability of the elephant habitat were analyzed using several corresponding indices to understand the spatial distribution of anthropogenic activities and point out the areas for immediate conservation needs. The research results show a rapid change in land use between 2013 and 2022, with forest cover significantly decreasing and cultivated land increasing. Habitat degradation index data indicates that changes in land use have resulted in a significant decline in habitat quality due to palpable human pressure. This study also highlighted the eastern boundary of the study region as a possible risk zone for elephant habitat, where the tourism sector is expanding. Despite the potential to improve local livelihoods, these economic activities would eventually negatively influence elephant habitats. The integration of decision support technology with the results provided by this study can help stakeholders and policymakers create sustainable land-use plans that are ecologically diligent.
