Abstract

We conducted a floristic survey of tree-shrub component in the Ecological Reserve Sanga da Bica, a urban forest fragment in Sao Gabriel municipality, Rio Grande do Sul, Brazil. The area with six hectares approximately of riparian vegetation it is a remaining composed of dense vegetation, well known for its history, historians say this place would have fallen Sepe Tiaraju. Considering the fundamental role and level of degradation present in riparian areas, this study aimed to know the floristic composition of tree-shrub component of the area. We founded 93 plant species at 40 plant families. The taxons most representative were Myrtaceae, Fabaceae, Asteraceae. Twenty exotic species have been identified, located near the edges of the forest fragment and in locations characterized by intense movement of people, their occurrence is probably attributable to the spread of seeds of exotic fruit species.
