Flora of the Private Reserve of Nature Patrimony (RPPN) Carneiro Farm, Lagamar, MG, Brazil

Abstract

The creation of nature reserves in Cerrado is important to maintenance of representative areas of this bioma and to development of studies about its flora and fauna. This study aimed to characterize the physiognomies and the arboreal and bush flora of the RPPN Carneiro Farm, located in the region of Lagamar, MG (17º57'-17º59'S and 46º45'- 46º48'W). Data was collected between November 2002 and November 2003. The similarity of flora was valued using the Sorensen index. The RPPN included gallery forest, semideciduos dry forest, cerradão and cerrado. The gallery forest is not very representative and occupies 1.7% of the RPPN. In this formation 37 species were found (23 exclusive) and 19 families. The most representative families were Fabaceae (7), Moraceae (6) and Euphorbiaceae (4). Semideciduos dry forest occupies 21.7% of the area and presented 100 species (53 exclusive) and 35 families. Fabaceae (15), Melastomataceae (11) and Myrtaceae (10) were the most important families in this formation. Cerradão, due to disturbances occupies only 4.1% of the RPPN. In this habitat 34 species were found (five exclusive) and 23 families. The families most representative were Fabaceae (5) and Myrtaceae (3). The cerrado, the most representative physiognomy of the RPPN, occupies 54% of area. This formation presented 169 species (144 exclusive) and 46 families. Fabaceae (22), Asteraceae (18) and Malpighiaceae (15) were the most important families. The flora of RPPN was different among its habitats because the Sorensen index found was less than 0.5 in all comparisons. The variety of habitats found in the RPPN Carneiro Farm and the richness of the flora of its formations make this reserve very important to the maintenance of biodiversity in the region of Lagamar.
