High conservation value forest approach on palm oil sustainability management brings heterogeneity in landscape perspective, but ecologically it may susceptible for amphibians community conservation, due to habitat fragmentation that may act as dispersal barrier, through matrix permeability and corridor effectiveness. Objective scientific observation on impact of agricultural activity on amphibians dispersal could be used to help mitigation efforts. This research aimed to analyze amphibians diversity similarity on landscape elements, analyzing amphibians dispersal by proving amphibians diversity correlation with distance from core area on corridor and matrix, comparing direct/non direct link corridor to core area and upstream/downstream diversity, and distribution spread and dispersal ability at landscape elements. Visual Encounter Survey (VES) with transect design method was conducted in Core Area, matrix and corridor. Total 1055 individual Found at site consist 5 Family, 9 Genera and 27 species, there are no significantly different in amphibians diversity due to distance correlation to core area, direct/non direct link and upstream/downstream corridors but significant on core area-matrix distance correlation. Almost all forest specialist has limited distribution to core area and corridor and aquatic species suggest capable to survive than terrestrial species through to dispersal ability in landscape element. corridors only effective working for aquatic species and habitat fragmentation effect is vary in each species.
