摘要
The knowledge on forest patches in rural properties allows. the application of a correct environmental administration, promoting their conservation and restoration in degraded areas. By using the softwares SPRING and FRAGSTATS, the landscape was characterized with emphasis on the patches of secondary Seasonal Semidecidual Forest, located in the municipal district of Carandai, MG, and the area around it, considering its evolution from the period of 1984 to 2007. It could be concluded that progressive increase in the total area of native forest occurred due to the appearance of new patches, and the individual area of each patch presented reduction tendency, what provided increase of the edge area, reducing the percentage of each patch which is the core area during the gap of the evaluated time. Despite the advantage of predominance of patches in simple geometric ways, with reduction of the edge effect, the quality of the landscape got threatened because it was predominantly constituted by small patches. The forest patches were still so distant one from the others (More than 200 meters), presenting small gathering tendency (result of the increase of the number of patches), however; still insufficient. Therefore, although the covering of native forest has presented increase of total area, in general, it lost in quality in the gap of the time considered.
