The study was conducted on two ski slopes situated on Jaworzyna Krynicka Mountain. One of them is located on south-east and the other on the eastern location. During the modernization of the slopes grasses and legumes mixture was seeded in three points on each of them. In the second year after sowing slopes were grazing by sheep 3 times. At the same time the floristic composition of the sward, sodding and yielding were estimated. Sown grasses as red fescue and tall fescue were present on all points in similar quantities. However, their participation in the coverage area was about 1/3 and smaller than the share of their seeds in the mixture. The share of sown perennial ryegrass and white clover in favourable habitats was similar to the share of seeds in the mixture. Evaluated ski slopes areas in the research points were characterized by good sodding and were classified as good pasture for sheep.
