Abstract

National Park plays important role in maintaining natural ecosystems such as freshwater ecosystems. Meru Betiri National Park is loacted in southern East Java, it covers two regencies, Banyuwangi and Jember. A recent survey was carried out in two resorts, Bandealit and Andongrejo, to study the diversity of freshwater gastropoda. We had collected 86 specimens which consisted of five families, seven genera, and nine species. Seven species were found from Andongrejo and four species were found from Bandealit. River in the Bandealit primary forest area had the highest diversity with four species. The relations between diversity and environmental conditions will be discussed briefly in this paper.
