Abstract


As a source of water, river is very important to be maintained and preserved, both its quantity and quality, because for almost all activities of the Indonesian people do require clean water primarily as a source of drinking water. Up to now, there is no monitoring of riparian vegetation in the upper watershed conservation as a sustainable river management. The purpose of this research is to develop a conservation model in upper  watershed of Brantas River based on riparian vegetation bioindicator, to realize sustainable river management. This study used survey method to observe riparian vegetation as bio-indicators of river environmental quality. The research was done by exploring physic and biology aspects of the Brantas River’s environmental conditions.  The result of this research showed that riparian vegetation diversity with Order 61 plants, 71 familia and 188 species shows good diversity. Riparian vegetation in terrestrial ecosystems is an important zone to regulate the flow of the movement of nutrients and energy. Important Value Index of riparian vegetation was more than 10% represented as vegetation phytosociology  was quite good. The main constituent of ecosystems Riparian were Lithocarpus sundaicusEngelhardia spicataEucaliptus albaOmalanthus giganteus, Pinus merkusii, Rouvolfia serpentina, Melastoma candidum, Oplismenus compositus, Pennisetum purpureum, Polygonum barbatum, Rouvolfia serpentina, Rubus molucanus, Rubus rosaefolius, Tetrastigma dichotomum, and Tithonia diversifolia. As whole, based on riparian vegetation, Brantas River’s quality was in a good condition.
