N2 - Within the Wielkopolska National Park (W Poland) 225 species have been recorded, which accounts for 48% of thePolish bees fauna. Modern investigations have failed to confirm the occurrence of 44 bee species that were recorded in the Park in the 1930’s. Among them, 19 species occurred in habitats that were later transformed to a large extent, so these species could really have disappeared. However, 80% of the 44 species are still recorded in adjacent regions, so the changes in the fauna of the Park seem to be only local. Thanks to the extensive knowledge of the bee community of the Park, this is a good area for monitoring quantitative and qualitative changes in bee resources.
