The Difference of Macro-Benthic Diversity in Riparian Vegetation and less Vegetation Area

Abstract

Bedengan a secondary forest area is located in Selorejo village, Dau subdistrict, Malang. Riparian landscape in Bedengan area occur degradation caused by human activities that make areas in Bedengan as citrus plantation and camping area. This study aimed to compare benthic macroinvertebrate community structures between riparian vegetation and less riparian vegetation on camping area Bedengan Stream. The sampling sites were divided into five types of the stream: less vegetation area (pool and current) and riparian vegetation area (pool, current and riparian). There are 21 taxa founded in Bedengan stream that distribute 10 taxa can be found in less vegetation (9 taxa in current area and 6 taxa in pool area) and 20 taxa can be found pada area vegetation (10 taxa in current area, 14 taxa in pool area, and 17 taxa in riparian area). There are 21 taxa founded in Bedengan stream that distribute 10 taxa can be found in less vegetation (9 taxa in current area and 6 taxa in pool area) and 20 taxa can be found pada area vegetation (10 taxa in current area, 14 taxa in pool area, and 17 taxa in riparian area). The habitat character will determine the abundance of benthic macroinvertebrates in this context the more species in a location the better the quality of the habitat.
