| Abstract: |
In landscapes of the eastern U.S.A., deforestation and reforestation are continuing processes. To better understand these processes, we documented the change in density and size of forest islands within individual landscape types of central New York. Thirty-one 30-kml sample landscapes were subdivided into 1-ha cells, and the cells were classified according to five land uses - forest, other natural vegetation, agriculture, urban, and water. Sample periods were 1938, 1959, and 1978. Using a cluster analysis, sample landscapes were grouped according to seven landscape types - urban, suburban, agricultural-urban, agriculture, transitional-urban, transitional-agriculture, and forest. The intensity of landscape use determined the frequency of fragmentation, elimination, consolidation and emergence of forest islands. The suburban landscape type had the highest rates of fragmentation, elimination, and emergence. In contrast, the forest landscape type had the lowest rate for those processes but had the highest rate of consolidation. By conducting such spatial and temporal analyses, regional managers can gain insight into how the individual attributes of landscapes might change through time under different management regimes. |
