Biodiversity is the basis of the state of an ecosystem and our entire planet. This study aims to assess the soil profile’s effects on the native flora species on mount Kasunogan. The research was conducted on the west ridge of mount Kasunogan in Barangay Aclan, Nasipit, Agusan del Norte. Flora species of shrubby trees were assessed along with the soil profile on the area. The researchers established three quadrants where leaf and soil samples were taken for assessment. The botanical expedition on mount Kasunogan recorded 37 native flora species. The Malatambis was present on all quadrants, while other species occurred only in one or two quadrants. These flora species have characteristics that allowed them to thrive on the mountain. The soil was determined acidic, and nutrients like potassium, phosphorus, and organic matter mostly ranged from low to moderately low. Planting Falcata, Narra, and Agoho should be considered since these species can withstand intense exposure to sunlight and acidic soil. However, exotic plant plantations must be well studied because there were no exotic plants around in the area.
