Dinadiawan River Protected Landscape
The Dinadiawan River Protected Landscape is a protected area covering the stretch of the Dinadiawan River from its headwaters in the Sierra Madre mountain range to its mouth on the Philippine Sea coast of the village of Dinadiawan in Aurora province, Philippines. The park covers an area of 3,371.332 hectares (8,330.74 acres) and includes its surrounding forested mountains, waterfalls and springs in Dipaculao municipality. It is composed of 2,645 hectares (6,540 acres) of forested area, 323 hectares (800 acres) of grassland, 151 hectares (370 acres) of forested shrubland, 144 hectares (360 acres) of cultivated area, and 108 hectares (270 acres) of the Dinadiawan River. Its forest cover consists primarily of dipterocarp trees like tanguile, mayapis, white lauan, red lauan and bagtikan. It serves as a habitat of wild fauna such as the Philippine deer, Philippine long-tailed macaque, Philippine warty pig, spotted wood kingfisher and pygmy swiftlet.
