This dataset contains species distribution, abundance and identity data of benthic invertebrates from Jervis Bay, NSW. Epifauna samples were obtained every 3 months for 3 years from 4 sites in mangroves and saltmarshes around Jervis Bay, between October 1988 and July 1991. Taxa identified comprised 28 species (20 molluscs, 7 crabs and 1 barnacle). Tatea spp. and Assiminea buccinoides were the most common gastropods around Jervis Bay. The data are part of the Jervis Bay Marine Ecological Study. NB - As the database has been lost, the only data still available are those published in the JERVIS BAY BASELINE STUDIES Final Report.
