The mountain range of Kayapa is watershed of five Dams namely: Ambuklao Dam, Pantabangan Dam, Magat Dam, San Roque Dam and Binga Dam. Almost all mountains are covered by pine tree and some endangered Forest Trees like almaciga, narra, etc. Flowering plants are also growing well in the forest. However, because of lack of awareness, residents are gathering some flowering plants esp. wild orchids. Other forest products like almaciga, narra are being cut down and sold to furniture. This is the result of weak enforcement of environmental laws and lack of environmental awareness.
