BRACKMANN, Cátia Eloísa  e  FREITAS, Elisete Maria de. Tree and shrub floristics of a fragment of the riparian forest surrounding Boa Vista Stream, Teutônia, Rio Grande do Sul State, Brazil. Hoehnea [online]. 2013, vol.40, n.2, pp.365-372. ISSN 2236-8906.  https://doi.org/10.1590/S2236-89062013000200007.

The riparian vegetation plays important roles in soil protection and ecosystem conservation. The aim of this study was to inventory the diversity of tree and shrub floristics in a fragment of the riparian forest at Boa Vista Stream, in Teutônia, Rio Grande do Sul State. To survey the species, we performed exploring rides around the fragment, once a month, from March to October 2012. Were identified 50 species, 47 genres, and 24 families. The richest family in species was Fabaceae, followed by Myrtaceae and Euphorbiaceae, following the standards of other surveys on riparian vegetation in Rio Grande do Sul State. Considering the size of the area, the degree of human disturbance in their surroundings, and the number of species in other riparian forest fragments studied in Rio Grande do Sul State, species richness is high. Most species have a wide geographic distribution in the State.

Palavras-chave : floristic diversity; floristic survey; riparian vegetation.
