Changes in the forest cover after intense logging in southern taiga of the russian federation

Specific features of the forest cover formation after industrial timber cutting during a period of 50 years in southern taiga spruce forests (Kostroma oblast) are described. The statistical analysis of the forest use intensity, the forested area, and the dynamics of the age and species structure of forests was performed. Plans of forest stands obtained for five inspections and taxation databases of 1954 and 1997 were also used. The potentialities of analyzing the structure of forest mapping units using means of overlay in the geoinformation system are considered. Parameters for distinguishing forest compartments were calculated. The dynamics of these parameters reflect the natural development of forest, effects of adverse environmental factors, economic history of the region, and specific features of individual interpretation of the survey materials in forest management.
