SOWED MEADOWS RENATURALIZATION ON RECULTIVATED AREA OF SULFUR MINE „JEZIÓRKO”

The terrain of the Sulphur mine of “Jeziórko” new Tarnobrzeg was recultivated by seeding grasslands on the larger part of the area. In 2014 phitosociological researches were conducted on the vegetation of the grasslands. The aim of the research was to determine botanical composition and indicate the plants that succeeded in the area. It was found that with years, botanical composition of grasslands was totally different form the original composition of seeds used. The changes lead to the re-neutralization of grassland swards which change from the areas which are regularly mowed. After a number of years without mowing, the plant associations were the same as on natural grassland ecosystems.
