Topography in this area dominated by steep slopes, 60% area located on altitude between 0-499 m, 35% on altitude 500-1000 m and 5% above of 1000 m. Wai Ndae River, flow pass through this area and emptied into Sawu Sea (Butchart et.al.1996, Gatur et.al.2000, Trainor & Lesmana 2000).
Butchart et.al.(1996) found Wallace's Hanging-parrot Loriculus flosculus on altitude between 450-980 m, in groups up to 20 birds.
