Over the past decades, as a result of the economic use of forests, the impact of fires and biotic factors, the forest cover has undergone significant anthropogenic transformation. In certain forest conditions, reforestation is delayed for a long period, which leads to the accumulation of non-producing forest lands. The aim of the work was to develop a methodology for determining the criteria for accessibility of forest areas for carrying out reforestation activities on the example of the territory of the Taezhinsky forestry of the Krasnoyarsk Territory. The area is dominated by deciduous plantations of average productivity. In the surveyed areas, natural regeneration is represented by soft-leaved species - birch and aspen of medium and large size categories from 1000 to 6000 pcs/ha. There is no natural regeneration of coniferous species. In these areas, it is necessary to create forest crops. The availability of forest areas for carrying out reforestation activities is limited by the transport, ecological and economic accessibility of forest crops. Within the boundaries of transport accessible quarters for carrying out reforestation activities, areas are identified that are suitable for soil and forest growing conditions for creating forest cultures with promising forest inventory characteristics not lower than grade III. The presented conditions correspond, first of all, to the green moss and forb groups of forest types. These plots constitute the second zone of silvicultural zoning, that is, an outstanding characteristic within the transport accessible quarters. The first stage of development includes forest areas of the II class of bonitet and higher, the second stage - III class of bonitet. Areas of quality class IV and below are reserved for natural reforestation.
