Macrozoobenthos is a group of important fauna in mangrove ecosystem. Mangrove rehabilitation is required to increase biodiversity and density of fauna, including macrozoobenthos. The aim of this research was to study influence of biotic and abiotic factors to diversity and abundance of macrozoobenthos. The research was conducted at natural and rehabilitated mangrove forest in Percut Sei Tuan, east coastal of North Sumatra. The results showed that density of macrozoobenthos were significantly correlated to the soil texture, soil organic carbon and pH. Besides, macrozoobenthos diversity was mostly influenced by stand basal area, salinity and silt proportion of soil texture.
