The results showed that in area of Wangkang Hill found as many as 16 species of natural orchids, with details of all types are epiphytic orchids. The number of individuals is 165 orchids. The index of species diversity (H') is more than one that is 1,103 and for each altitude ranges from 0.766 - 0.966, with the largest species diversity occurs at altitude of 300 - 345 m asl.
