Abstract
Research on the study of the diversity of mollusks in the mangrove forest area of Cengkrong Beach – Trenggalek has an important role in knowing the decline in the ecological function of mangrove forests due to exploitation. Exploitation that occurs is illegal logging of mangrove trees. The purpose of this study was to analyze environmental conditions through physico-chemical parameters, analyze the diversity of mollusks, and analyze the relationship between environmental conditions and the diversity of mollusks in the mangrove forest of Cengkrong Beach - Trenggalek. Sampling was carried out at three stations with 27 plots. Sampling using purposive sampling technique with the belt transect method then measures environmental conditions. Data analysis using regression test. The results showed that the conditions of pH, temperature, salinity were normal. The diversity of mollusks found was 13 species consisting of 11 species from the Gastropoda class and 2 species from the Bivalvia class. Furthermore, there is a significant relationship between environmental conditions and the diversity of mollusks.
