Abstract
Abstract Mangrove association mollusks was one of the indicator to describe the status of mangrove ecosystem’s health. This research aimed to analyze the condition of mangrove rehabilitation based on the composition of association mollusks compared with non-rehabilitation area which resulted from a natural succession. It held on July 2019 at mangrove conservation area Bagek Kembar, West Lombok. Data collection method used stratified random sampling by placed some plots sized 1x1 m randomly in a larger plot (10x10 m) which have been determine randomly before. The result showed that there are 24 species of association mollusks which belong to 11 families found in these area. The abundance of mollusks in natural and rehabilitation mangrove was different which is in a row 50.2647 ind/ m 2 and 88.4 ind/ m 2 . Cerithidea cingulata has the highest abundance among the other species with the number of abundance 48.8 ind/m 2 in non-rehabilitation ecosystem and reach 29.17 ind/ m 2 in rehabilitation area. Based on this research, the condition of mangrove conservation Bagek Kembar still categorized as non-stable condition for supporting the survival of mangroves associated mollusks.
