Four conservation methods were compared on grassland unused for 30 years as follows: 1. control; 2. one cut, herbage mass was spread for mulch; 3. one cut, herbage mass was removed; 4. two cuts, herbage mass was removed. Experiments were carried out on a hilltop and hill slope. The highest increase in the total number of grass shoots was characteristic of the control on both parts of the hill. At the end of the conservation period, 38 herb species were identified in the trial. Treatments 1 and 2 were richer in floristic diversity (27-33 species) than the treatments 3 and 4 (20-25 species). The treatments on the hill slope had a more diverse species composition than those on the hilltop. The proportion of legumes in the herbage mass increased from 0 to 27.7% in the swards where cut herbage was removed.
