Análise espacial de fragmentos florestais nativos em uma empresa florestal

Abstract

The search for ecological knowledge about the forest fragments can improve the rural property management and the conservation of natural areas, in addition to be a tool for forest regeneration. For the ecology metrics calculation was used the computacional application QGis and the Landscape User Manual made by Brazilian Agricultural Research Corporation (Embrapa Forestry) with emphasis in forest native areas. The mapped fragments were divided into sized classes. In general, 1.691 forest fragments were foundin all the area, which the small fragments were found in greater number (1.373), representing only 1,8% of the forest analyzed area. However, large fragments between 100 and 500 ha were most important in area (44,3%), followed by fragments between 500 and1.000 ha (30,5%). The landscape metrics demonstrated high index of Habitat Interior (76,69%) and Edge (18,95%) in mapped areas. Large forest fragments were more significant in area, and the high index of Habitat Interior, demonstrated the relevance to thebiodiversity conservation.
