Pinega State Reserve is located in the Northern taiga subzone of European Russia. Forest management in this territory started at the beginning of the XX century. Several large burnings were documented in the studied area over the last 200 years. Clear-cutting of the territory now occupied by the nature reserve started in 1960s. In the buffer zone they have been continued till present days. Detection of burned areas occurred before 1975 was performed by updating old maps based on Landsat imagery of 1988 and 2001 by means of discriminant analysis. Detection of areas disturbed after 1975 was carried out by classifying Landsat images of the synthesized image pairs for 1975–2014. A disturbance map of the reserve vegetation over the past 200 years was compiled by combining layers obtained by these two methods. Both core and buffer zones of the reserve have been considered in the present study. Till the beginning of the XXth century, the only kind of large-scale disturbance in the territory was forest fires. Results of image interpretation along with historical data enable dating individual disturbances. The obtained spatial data allow determining areas affected by disturbances in different periods and revealing tree species composition of forests emerged in these areas.
