Levantamento das Pteridophyta na Reserva Biológica das Perobas nos municípios de Tuneiras do Oeste e Cianorte, Paraná, Brasil

Abstract

The knowledge about Pterydophyta in the state of Paraná is still scarce, but this group of plants has great environmental importance, providing shelter and support for other plants. This study aimed to carry out the floristic survey of Pterydophyta and classify their ways of life in Semideciduous Forest stretches, with enclaves of Araucaria Forest in Reserva Biológica das located in Tuneiras do Oeste and Cianorte, Paraná. The weekly raids were conducted along trails, and approach within waterways and forest edges. They recorded 44 different species of Pterydophyta, distributed in 17 families and 26 generals. The Polypodiaceae family was the richest, registering eight species, followed by Pteridaceae with seven and Dryopteridaceae with five species. Together this families account 45.54% of all. Regarding the way of life, terrestrial species were most, registering 24; followed by epiphytes with 13 species; the arborescent, rupicolous and marsh reached two species and hemiepiphyte with only one. The presence of all forms of life gives the Reserve indicative of favorable environmental conditions such as shading and moisture.
