historical maps - Opis:
- The aim of this work was to present changes in the fragmentation of forest area characterised by a two−fold increase in forest cover during the last century. The Forest Area Density (FAD) indicator was utilised in order to determine the forest fragmentation for the raster analysis of numeric maps. Its calculation was made using GuidosToolbox software. The research covered 1862 km2 of a predominantly post−glacial area of the Ińsko Lakeland, located in the north−western part of Poland. At the end of the 19th century, forests occupied 273.0 km2 of this area, while at the beginning of the 21st century their area coverage increased to 612.5 km2. The observed increase in the forest cover was associated with changes in forest fragmentation, which was analysed using the FAD. When comparing the two surveyed periods on the synthetic result maps obtained by utilising the FAD method, visible changes can be seen in individual forest categories, which indicate a decrease in the fragmentation of forest areas. The use of fragmentation measures is justified because according to the data found in the literature, the recently observed increase in forest coverage in many areas of Europe does not always determine the decrease in their fragmentation. This verifies the legitimacy of using the FAD indicator in the context of ecological and economic assessments.
