LumintaoRiver_RiparianVegetation_SurveyData_2026.xlsx

This dataset contains detailed survey data on riparian vegetation structure, floristic composition, diversity indices, and sediment accumulation along the Lumintao River, Occidental Mindoro, Philippines. Data were collected across eight transects representing a gradient from upper river reaches to the river mouth, encompassing areas with varying levels of disturbance and siltation. Contents include: Structural vegetation attributes: tree density, canopy cover, basal area, and diameter at breast height (DBH) distributions. Floristic composition: species lists, frequency, relative density, and Importance Value (IV) for trees. Diversity indices: Shannon diversity, Simpson diversity, and evenness for tree, understorey, and ground layers. Sediment measurements: sediment depth as a proxy for siltation and anthropogenic disturbance. Transect metadata: georeferenced sampling locations and site characteristics. The dataset supports analyses of floristic erosion, arrested succession, and the impact of sedimentation on riparian biodiversity. It can be used for ecological assessment, river management planning, and further comparative studies in tropical riparian systems.
