Abstract : Survey of biodiversity had intended to identify which species of wild fauna and flora, inhabit the area near the Lageado Hydroelectric micro hydro power plant that will go through the environmental licensing process to be reactivated. The study area encompasses 18.52 hectares and is located in the watershed of the Ribeirão Lavapés in Fazenda Lageado, Campus of the Universidade Estadual de São Paulo in Botucatu/SP. To estimate the richness and diversity of fauna was used the indirect method (records of footprints and droppings), allowing the registration of species with diurnal, crepuscular and nocturnal habits (WILSON et al., 1996). The floristic survey was accomplished through walking in the area, marking the known species and retiring samples of known not for traceability in laboratory of Botany. And still it was examined whether the water quality of the Ribeirão Lavapés according to the parameters described in Conama resolution 357/05 where he analyzed pH, OD, BOD, turbidity, alkalinity, total coliforms and fecal matter, suspended solids, nitrogen and phosphorus. Through remote sensing system free gvSIG, mapped the area of study and was drawn up the map of land use. In wildlife survey, between mammals and birds were found: Nasua nasua, Eira barbara, Hydrochoerus hydrochaeris, Dasypus novemcinctus; Penelope superciliari, Campephilus Falconet, Celeus flavu Tersina viridis, Thamnophilus doliatus, Aramides saracura, Synallaxis gujanensis and other. When the floristic survey 50 different species have been identified, among them stand out: Aloysia virgata, Sibipiruna peltophoroides, Holocalyx balansae, Gallesia integrifólia, Michelia champaca, Chrysophyllum gonocarpum, Caesalpinia férrea, Persea americana, Eugenia uniflora, Mangifera indica and Handroanthus spinosa, and others. In the mapping of land use were found the classes: native vegetation, water course, buildings, agricultural area and dirt roads and paved. In relation to water quality, only the parameters pH and turbidity are suitable according to the resolution Conama. Even with the low quality of the water of the Ribeirão Lavapés several species of mammals and birds are able to survive in this area. The presence of fruit trees is a good attraction for the fauna and avifauna that contribute in seed dispersal. With the mapping of land use, it was found that the riparian forest is at odds with the Conama resolution 303/2002 that in article 3 permanent preservation Area is the area located on marginal range, measured from the highest level, on horizontal projection, with minimum width of 30 meters to the water course with less than ten feet wide..
