The violation of plant-soil surface during the de-velopment of mineral resources in the High North require subsequent resurfacing technogenic dis-turbed lands. The article describes the features of a turf-protective layer on the surface of the tundra us-ing perennial grasses and biological remediation techniques. Empirically derived data on the qualita-tive and quantitative charac- teristics-forming sod coating characteristics of growth and development of the root system of plants in permafrost condi-tions, identified transising species and varieties of perennial grasses to combat water erosion. The details set out the conditions and methods of the research. When analyzing the results of research to use charts and tables. Fast creation of a layer of sod sown perennial grasses effectively reduces the passage of surface horizons of the soil-forming rocks in the thixotropic state and reduces the kinet-ic energy of the water flow. Especially intensive formation of turf-protective cover was observed in the first three years. The progressive increase in the qualitative and quantitative characteristics of the artificially created protective layer was observed at the grass-roots of grasses. This was due to the advent of the third year of life, in addition to the de-velopment of vegetative and generative more: grass began to form viable seeds, germinating in the following years. In upland grasses seed repro-duction throughout the studies was observed. Their weak turf properties were also due to the low densi-ty of grass and weak winter hardiness. For the pro-tection against water erosion damaged land surface proposed the creation of the sod layer by seeding the grass-roots of perennial grasses meadow grass and red fescue with simultaneous application min-eral fertilizers in a dose N60P60K90.
