This study was carried out to clarify the properties of Arbuscular Mycorrhizal Fungi(AMF) from different types of land used at Sunbarjaya in Southern Sumatra, Indonesia. The soil samples were collected from primary forest (P.F. : Hopea mengarawan. H.sangal, and Dryobalanops spp.), secondary forest (S.F. : Daemonorops oblongata. H. ficus and H. calamus), coffee field (C.F. : Coffea robusta) and native grassland (N.G. : Imperata cylindrica) where were about 1,200,100,800 and 800 m above sea level, respectively. Sampling sites for C.F. were selected from three locations along the hillslope. There were four genera and ten species of AM fungal spores identified from the P.F., S.F., C.F., and bush soils of the Sunbarjaya areas. Glomus etunicatum. G. constrictum and G. aggregatum were found in all land uses. The total spore numbers of G. constrictum and G. aggregatum were much greater in the C.F. soils compared to other soils. But, the number of genera and species in the C.F. soils was low compared to the P.F. and S.F. soils. G. constrictum predominated in all soils and G. aggregatum only predominated in the C.F. soils.
