- Аннотация: A grazing project is under implementation since 2015 in the Tula region, near the Gurovsky quarry of HeidelbergCement Rus LLC. The project aims to restore a meadow in an abandoned arablefield intended for limestone mining in 2025. The soil from this meadow will be used for the remediation of the quarry, which is being developed now. The restoration of biodiversity shouldstrengthen the ecological functions of the natural meadow community. This will increase soilfertility, which will be used to restore the currently developed quarry.In 2015, the main part of the experimental plot was ploughed up and then grassed. We appliedseveral methods of meadow restoration:- year-round grazing by livestock (10 Shetland ponies per 10 hectares of a 10-year-old poormeadow and 20 Kazakh white-headed cows per 42 hectares of sown grasses) and feeding it withhay collected from the natural meadow,- extended over time mosaic mowing of grass in hayfields (30 ha),- sowing hay from natural meadows on parts of hayfields (1 ha),- planting target species and sowing them in hayfields.The number of plant species increased in the pony pasture from 69 to 103 species, in the cowpasture from 109 to 136 species, and in the hayfield from 104 to 137 species.The average aboveground plant biomass was 3.7 t/ha in the parts of the hayfield sown with hayfrom the natural meadow, 2.0 t/ha in the rest of the hayfield and 3.0 t/ha in the cow pasture. Forcomparison, it was 3.2 t/ha in a natural meadow. The average hay yield in the Tula region in 2016was 2.1 t/ha.The fastest restoration is in the plot mown for hay, sowed with the seed mixture from the natural meadows. The invasive species Solidago canadensis and Erigeron annuus damage the meadows under restoration. The vegetation of the experimental plot belongs now to the basal andderivate communities of the Molinio-Arrhenatheretea class.
