The objectives of the survey were to analyse structure mollusc communities in mining subsidence reservoirs that created as a result land over exploited hard coal seams and determine most predictive environmental factors influence distribution species. are located urbanised industrialised areas along Trans-Regional Highway, which has high volume vehicular traffic. They all have same sources supply but differ physical chemical parameters water. In total, 15 species recorded including four bivalve Among them Anodonta cygnea is classified Endangered according Polish Red Data Book Animals also Near Threatened European List Non-marine Molluscs. Eleven included on Molluscs Least Concern. Conductivity, pH concentration calcium associated with Canonical correspondence analysis showed Potamopyrgus antipodarum, Radix balthica, Physella acuta, Gyraulus crista Pisidium casertanum higher conductivity lower values. A. cygnea, anatina Ferrissia fragilis negatively influenced by these results this provide refuges for rare legally protected they play an essential role dispersal alien well.
