The number of breeding pairs fluctuated between 19 and 31 (average = 25.7). The highest number of pairs was observed in 1980. Complete data about the breeding succces are presented in appendix 1. We observed a rapid decline in the number of breeding pairs through the 1990s. The probable reason for the decline was the break down in the national farms system and which resulted in a cessation in grass cutting and the removal of cows from pastures.}, type={artykuł}, title={Wieloletnia dynamika liczebności oraz sukces lęgowy bociana białego (ciconia ciconia) w kolonii we wsi Kłopot nad Odrą = Long-term dynamic of white stork population and breeding success in colony in the village Kłopot near Oder, west Poland}, keywords={3 Międzynarodowa konferencja "Ochrona i rekultywacja terenów dorzecza Odry: zrównoważona gospodarka zasobami naturalnymi" (24-25.06.2004)}, }
