Flora vascular em unidades de conservação no município de Mato Rico, Paraná, Brasil

Abstract

Knowledge about Conservation Units is still scarce; about 71% of the area of conservation units in Brazil have less than 0.01 species records per km². The present study aims to characterize the composition of the vascular flora and the dispersion syndromes in three Conservation Units of the municipality of Mato Rico, Paraná State, Brazil. A total of 297 species were found, distributed in 213 genera and 79 families. Of these eight species are exotic. The main families were: Fabaceae (19 species), Asteraceae (15), Euphorbiaceae (14), Solanaceae (12) and Sapindaceae (10). In relation to the habit, herbaceous plants were predominant (44%), followed by shrubs (26.6%), climbing plants (22.2%), trees (20.2%) and subshrubs (20,5%). One fifth of the species had a variable habit. Terricolous plants were predominant (93%), followed by rupiculous (12.1%), epiphytes (6.4%), aquatic (2%), hemiparasites (1%) and 13% species presented variable use, being classified in more than one category. Zoochory was the predominant dispersal syndrome in the total flora (38%), followed by anemochory (35%), autochory (21%) and barochory (4%). We recommend the continuity of the floristic survey for these Conservation Units.
