This study aimed to describe the diversity of mollusk species in rehabilitated and natural mangroves. The research variables included of mollusk species and individuals (gastopods and bivalves). The method used was descriptive, with observational techniques. There were 39 species of mollusks and 16 families with 2,922 individuals. There were 39 species of mollusks and 16 families with 2,922 individuals. These included 34 species of snail groups (Gastropod) and 5 species of shellfish groups (Bivalve). In addition, the percentage distribution of mollukc species was 18% (8 species out of 39 species) with diversity index (H) 1,09, dominancy (C) 0,12, and evenness (E) 0,84 (natural), then (H) 1,22, dominancy (C) 0,08, and evenness (E) 1,85 (rehabilitation). In addition, species diversity index values in the two mangrove forests were 2.52 (Ruar Village) and 2.70 (Yenusi Village) in the "moderate" category. A total of 72% of mollusk individuals were found in mangrove forests of Yenusi village, and the remaining 28% were present in Ruar village. This showed good adaptation, considering that the presence of mollusk species and individuals in the mangrove rehabilitation area was higher compared to their natural habitat. This showed that rehabilitation greatly influenced species composition at rehabilitation locations compared with natural locations.
