O článku:
Changes of landscape configuration, especially in the forest landscape, have raised concerns about habitat fragmentation and its impact on biodiversity. Effective conservation measures require knowledge about the factors that cause the forest fragmentation and about their effects. Landscape metrics based on remote sensing data can assist in quantifying the fragmentation process and in assessing habitat quality of the remaining forest. The CORINE Land Cover (CLC) databases represent appropriate input data that characterize the landscape in Slovakia in 1990 and in 2000. Therefore, the purpose of this study was to present the fragmentation assessment using the CLC databases. Quantification of indices: number of forest patches, mean patch size, total forest area, percentage of study area occupied by forest, total forest edge, forest proportion and forest connectivity based on both vector and raster data is presented in order to document the state and changes of forest area and its configuration. The study areas consist of 4 administrative districts situated in the northern part of Slovakia. Our results document not only the decrease of forestland in the period 1990-2000, but also a remarkable decrease in proportion of the core forest area. On the other hand, the area of the forest edge, forest patch and perforated forest categories increased.
