Lumbricidae in the Process of Monitoring of the State of Land Reclamation of Former Sulphur Mine in Jeziórko

The aim of the research was to rate the advancement of the naturalisation process that concerned the area recultivated after the sulphur mine in Jeziorko. It was rated by analising the diversity of populations of earthworms from chosen five spots (field I, II, X, XX and XXI) differentiated in terms of time and direction of reclamation. Earthworms were obtained by the mixed method, according to Zajonc. The results were analyzed statistically. On the field II reclaimed for the longest period in forest direction, there were all 7 species of Lumbricidae found, and on field X (shorter reclamation) - 5 of them. In the open spaces of fields I, XX and XXI, representatives of the examined group were not presented. On field XX and XXI, earthworms were preserved only within individual old trees (Malus Mill., Populus L. poplar) growing in this area even before the period of land degradation by the sulfur mines. Within the crowns of these trees, poor clusters consisting of 1 or 2 species of earthworms were discover (A. rosea and/or A. caliginosa)
