The objective of this study was to characterize the floristic composition of trees and shrubs of the Jaraguá State parkland (PEJ), contributing to the knowledge of its biodiversity. Reproductive botanic material was composed along three trails during a 12-month period. The field survey resulted in a flora of 262 native species, 153 genera and 55 families. legume family was the richest family (30 species), followed by Myrtaceae (26), Asteraceae (24), Melastomataceae (20), Lauraceae (16) and Rubiaceae (15). As mentio ned for early(a)(a) forest remnants in São Paulo metropolitan persona and surroundings, the PEJ flora is in a transition zone, where the master(prenominal) formation is the ombrophilous vague forest, but where species of seasonal semi-deciduous forest withal occur. Besides that, on that point is a completely different phytophysiognomy occurring in a region with rocky outcrops and low depth soils, in which cerrado species were found, and that deserves much sp ecific studies. In this site, the flora of grasses is the most abundant, and there argon also shrubs and trees sparsely distributed, many of them with low height and suberous trunk.
roughly specifically in this area there were 55 species of 41 genera and 18 families, from which 22 did not occur in the other sites visited. Asteraceae was the family with the higher number of species (15), followed by Myrtaceae (7), legume family (5) and Melastomataceae (4). Twenty exotic species were found along the trails. plunk for the fact that PEJ has a big area of secondary vegetation and that it is exposed to strong anthropogenic pressures, there were 14 species start to some threat category defin ed at the ordain red lists, reinforcing th! e importance of the Park for biodiversity conservation.
