Abstract. The article gives an assessment of the condition of natural forage lands of the East Siberian natural and economic region. This region includes the Republics of Buryatia, Tuva, Khakassia, Zabaykalsky and Krasnoyarsk Krais, Irkutsk region. Natural forage lands were zoned using materials of the agroclimatic, natural and agricultural, ecological landscape, soil and ecological, biogeochemical zoning, landscaping, environmental, ecological and geographical, soil and geobotanical maps, data of state land registration, library materials, statistical data of the Ministry of Agriculture of the Russian Federation and the Federal State Statistics Service. We also used the results of the previous zoning of natural forage lands of the country, library materials of the V.R. Williams All-Russian Fodder Research Institute and data of the Federal Land Inventory Service of Russia. On the territory of the East Siberian natural and economic region it were allocated 136 units of zoning, including 11 large (Arctic, Arctic and tundra, tundra and forest-tundra, northern taiga, middle taiga, southern taiga, deciduous-forest, forest-steppe, steppe and dry steppe zones and mountain areas), 34 medium (22 plains and 12 mountain provinces) and 91 small (49 plains and 42 mountain districts). Agricultural land occupies about 25 million hectares, or 6% of the area, including hayfields and pastures – 16.3 million hectares (3.5 million hectares of hayfields and 12.8 million hectares of pasture), or about 4% of the area and 66% of the agricultural land. Negative processes degrading the quality of agricultural lands of the East Siberian natural and economics region are erodibility (20% of arable land, 9% of pastures are erosion threatening, 31% of arable land, 12% of pastures are deflation threatening; overwetting (10% of hayfields, 4% of pastures); bogginess (11% of hayfields, 6% of pastures); stoniness of land (7% of arable land, 2% of hayfields, 24% of pastures). Most of hayfields and pastures are in need of improvement, including fundamental amelioration.
Keywords: agrolandscapes; natural forage lands; East Siberia; environmental condition of lands; rational nature management.
