Conhecendo a flora herbáceo-subarbustiva do Parque Estadual do Mirador, Maranhão/Brasil

Abstract

Knowing the herb-subshrub flora of Mirador State Park, Maranhão / Brazil. We carried out a floristic study of the Cerrado stricto sensu flora of the Mirador State Park in the center-south region of the State of Maranhão , aiming to know the species that make up its herbaceoussubshrub vegetation and to compare its floristic richness with these of other areas of Brazilian Cerrado. We collected botanical materials in plots established inside and outside of the area, for a better representation of the flora. To assess the similarity between different areas of Cerrado, we selected published papers referring to herbaceous-subshrub vegetation of Conservation Unit areas and then assembled a binary matrix to perform the statistical analysis. The families with the highest number of species were Fabaceae (18), Cyperaceae (17), Malvaceae (7) and Arecaceae (6). Of the species catalogued in PEM, 47% were herbs, 41% subshrubs and 14% climbers. The other Cerrado areas showed low similarity with PEM, characterizing a floristic distinction between the areas
