Biodiversity
The Philippine tarsier is known to be one of the smallest primates, categorized as an endangered species in the area. This nocturnal animal has been sighted at the Bolusao watershed and adjacent San Isidro village. The avifauna of the Bulosao River Watershed Forest Reserve is virtually unknown, but it is likely to be similar to those of the other IBAs on Samar, the Mt Cabalantian-Mt Capotoan complex and the Mt Yacgun-Mt Sohoton complex. The extensive forests in this IBA therefore probably support important populations of several of the threatened and restricted-range species of the Mindanao and Eastern Visayas Endemic Bird Area.

Tourism
There are four waterfalls in the Bolusao watershed which lies within the Samar Island Buffer Zone. These falls are Amandaraga, Pangi, Amanjuray, and Ban-Awan Falls located in Barangay Bolusao. Amandaraga and Ban-awan Falls are the main source of the municipality's water system. Meanwhile, Amanjuray Falls is the alternate hydro-electric power source of Lawaan wherein a mini-hydro power plant is existent nearby.
