Sumba Island, located in the southern part of EastNusa Tenggara, about 100 kilometers south of Flores Island, is 250 kilometers long with a total area of 10,845 square kilometers.
It is formed from volcanic crust fragments and limestone. The geological formation of Sumba is different from other islands in Nusa Tenggara, which originally derived from volcanic rock. The dry season in Sumba occurs between May and November.
The annual rainfall is estimated between 500 millimeters and 2,000 millimeters. Sumba has four types of forest (Banilodu and Saka, 1993). The deciduous forest is found along the rivers and lowland areas, while the semi-evergreen forests grow in the hilly areas, where the humidity is lower. The true evergreen forest is in area with higher humidity, about 700meters above sea level. Another type, the elfin forest, is found on Mount Wanggameti at 1,050 meters to 1200 meters above sea level.
Now, only 11 percent of Sumba Island is covered with forest, mostly in the south. The forest is home to a great variety of fauna, much of which isendemic to Sumba………….
