The transect method of soil survey was used to study the floral species and the soil and land characteristics in the multiple use zones in Mt. Isarog. The observation sites, which were based from the map produced by CARE Philippines, are located in Sto. Niño and Villaflorida, Ocampo, Camarines Sur; Payatan, Goa, Camarines Sur; Cawayan, Tinambac, Camarines Sur and in Panicuason, Naga City. The study determined the soil and other environmental characteristics at MINP multiple use zones; the existing floral species in the multiple use zones; land capability, soil fertility rating and soil suitability of the existing floral species, and generated land capability, soil fertility rating and soil suitability maps of MINP MUZs using the Geographic Information System (GIS). Most of the areas, particularly those located at the lower foot slopes, are generally fairly good land and classified as Land Capability Class De. This class denotes a land that requires very careful management and intensive conservation practices for safe cultivation. However, a small portion of the area located on the lower footslope in Sto. Niño is classified as Class Ce, which is a moderately good land but also requires careful management and good conservation practices because it is moderately eroded. The areas on the upper footslopes in the barangays of Payatan, and Villaflorida and Cawayan are classified as Class M because of the steep slopes and moderate to severe erosion. These areas are limited to pasture or forest use, but also require careful management.
