Florística e Ecologia de Samambaias e Licófitas como Indicadores de Conservação Ambiental

Abstract

The objective of the research was to characterize the floristic diversity and ecological patterns of ferns and lycophytes Ecological Park Gunnar Vingren as elements bookmarks environmental conservation. Floristic composition and ecological standards for the way of life, type of substrate and habitat was analyzed. 12 families, 22 genera and 28 species being Palhinhaea cernua (L.) Franco & Vasc were recorded. The only representative of the lycophytes. Pteridaceae, Dryopteridaceae and Polypodiaceae had the highest number of species and Thelypteris Schmidel, Elaphoglossum Schott ex J. Sm, Didymoglossum Desv. and Microgramma C. Presl and more species. The form of epiphytic life was dominant in 46.5% of the species; the most common type of substrate corticícola with 46.5% and floodplain forest with 32% of total species. The unique composition of species in a given habitat contributes to indicate the level of disturbance in conservation and environment, so necessary for environmental planning of the Park
