Environmental and biological studies

Campos Gerais are a high ecological relevance area considered as priority for conservation as includes grasslands under strong anthropogenic pressure. Recent environmental restoration studies pointed to the functional groups instead of species in developing strategies for restoration. In this study the Alagados´s native grassland vegetation was characterized by functional groups as a subsidy for this restoration plans. Fortnightly samplings occured from 2009 to 2010 in a 9,4 ha area. It were collected 439 species belonging to 56 botanic families; the most richness were: Asteraceae (123), Fabaceae (45), Poaceae (42), Cyperaceae (24), Melastomataceae (17), Myrtaceae (16), Lamiaceae (14), Verbenaceae (12), Lythraceae (11), and Eriocaulaceae (9). The higher functional groups were chamephytes (44,4%), cryptophytes (25,6%) and hemicryptophytes (15,6%) selected mainly by the rough winter conditions in southern Brazil.
