Abstract Acceleration land rehabilitation management of nickel post-mining in Sorowako has been main attention of PT. Vale Indonesia. This acceleration can be done by utilizing natural resources, especially microorganism’s indigenous endomychorrhiza. endomychorrhiza also called mychorrhizal arbuscula (MA) has got a lot of attention for its ability to form a mutualistic symbiosis with 80% - 96% of plant species. This study aims to determine the dominance of spores indigenous endomychorrhiza and its potential to accelerate land rehabilitation management of nickel post-mining, which is carried out in three phases; sampling rhizosphere, trapping spores, isolation and identification of spores MA types. The results showed that the dominance of genus indigenous endomychorrhiza in the area is Acalauspora sp (75, 06%).
