The spatiotemporal forest cover change is one of key factors determining the characteristics and processes in landscapes. The article analyzes long-term changes in the forest cover of the Central Russian forest-steppe from the mid-1980s to the first half of the third decade of the 21st century. The indicators of forest cover change, area and spatial characteristics of forested lands were studied on a network of 25 sites located within the region. The indicators included total forest area, average forest area, forest boundary length and forest density. Over a period of almost forty years, the average growth in forest cover in the region was 36 %, accompanied by an increase of 16.7 % in the average forest area and 40 % in the length of forested land boundaries. With an average increase in the number of forest areas in the region of almost 17 %, in some sites there was a decrease in their number due to the unification of forest areas in the process of their expansion and the advancement of boundaries. In most sites in the mid-1980s, the forest cover of the landscapes did not exceed 10 %, but during the study period, the share of those with forest cover from 10 to 30 % increased significantly. The increase in forest cover has led to a decrease in the variability of the spectral reflectance of the territories where forests have formed. A decrease in the coefficient of variation of reflectance was found in the visible, near and short-wave infrared ranges.
Keywords: forest area, forest cover, spectral reflectance, long-term changes, Landsat
