Aspectos da vegetação do complexo lagunar: Nísia Floresta, Papeba, Guaraíra e arredores

Abstract

A complete survey of all the aquatic, marginal and adjacent area of the lake complex was made. Among the material collected we can detach: - the macroscopic aquatic plants, prevailing in each lake environment, in an attempt to show their influence through environmental agents; - the marginal plants, emphasizing their influence in the environment; - the plants in the adjecent area, taking in to consideration, the geomorphological as pect which encloses the complex (dunes, bar rier spits, alluvial plains and tablelands). The whole complex is threatened by great than ges due not only to natural as wen._ as to artificial factors. These factors probably favor the proliferation of aqua tic plants and the reduction of the fauna in the "Nisia Flo resta" lagoon, owing to ecological unbalence
