FLORISTIC OF AN AREA OF CERRADÃO WITHIN THE NATIONAL FOREST OF PARAOPEBA – MINAS GERAIS

Abstract

This research studied the floristic composition of an area of Cerradão, domain Savanna, in the National Forest of Paraopeba - FLONA, municipal district of Paraopeba-MG, Brazil (19°16’19"S e 44°24' 06"W). A total of 30 plots of 10 x 10 m in transects of 10 x 100 m, totaling 3,000 m² were installed. The distribution of transects were systematically along the track, spaced 20 m apart. 1172 individuals/ha were sampled, totaling 61 species, belonging to 53 genera represented by 30 families. The families with greater species richness were Fabaceae (Leguminosae) (10) and Vochysiaceae (5), followed by Rubiaceae, Sapindaceae, Myrtaceae and Bignoniaceae (4). Out of 61 species identified, 44 (72%) are considered accessory and only 17 (28%) peculiar of Savanna, evidencing that the species of forest formations found in the cerradão seem to occur out of their distribution limit, characterizing the cerradão as a transitional vegetation between the forests and the Cerrado, once the Cerrado stricto sensu behaves as a mosaic of peculiar and accessory species, which are superimposed, along all its domain.
