Diversidade da flora vascular em unidades de conservação do Paraná: Mato Rico

Abstract

This study aims to contribute to current knowledge in three Conservation Units of Paraná: Municipal Ecological Stations of Cantú, Colombo and Juquirí. Three hundred and twenty species were recorded in the three Ecological Stations, distributed in 229 genera and 81 families. The five largest families are Asteraceae (25 species), Fabaceae (19), Euphorbiaceae (14), Solanaceae (14) and Sapindaceae (10) and together represent 26% of the vascular flora of the Ecological Stations. With the basis of forms of life, there was the predominance of herbaceous and shrub plants; and terrestrial species were predominant for the substrates use. The presence of ten threat species was recorded for the Paraná and Brazil. There were also nine exotic species, eleven of which were listed as invasive species in the state of Paraná. Analyzes of floristic similarity listed 1,160 species in eight study areas. The dendrogram of similarity shows the grouping of the three Ecological Stations studied, although the similarity index between them is low, less to 20%. These remnants have great importance, being indispensable to the programs of ecological restoration, formation of ecological corridors, control of exotic and invasive species, being realized to guarantee a state of conservation and preservation of the species.
