Numbers and distribution of Northern Lapwings breeding in Switzerland have undergone strong fluctuations over the last 150 years. In the 19th and at the beginning of the 20th century a decline to about 180 breeding pairs was noted. In the 1940s numbers started to increase again, when Lapwings began to nest on arable land. In the 1970s the population reached a peak with 1000 breeding pairs. In the 1980s a decline was observed again, which accelerated since the 1990s. In the most recent survey 2005–2008 only about 100 pairs (83–116) were found. This amounts to a decline of 78 % since the last national survey 1993–1996, carried out for the national distribution atlas. The number of 100 km2 squares occupied by Lapwings declined from 20.1 % to 6.6 % in the same period. In several regions Lapwings have completely disappeared. The decline was strongest in agricultural areas.
