Zusammenfassung (Deutsche Fassung)
The Ornithological Working Group of Recklinghausen District surveyed the population of Lapwing in 2016. The results are compared with a survey in 2003/2004. The population decreased from 391 to 161 territories, or by 59 %. The number of occupied grid cells also decreased by 59 %. For the ordnance survey maps 4309 and 4310, which cover parts of the Coesfeld and Unna districts, data from a survey in 1989/1990 were taken into account. While the population here only marginally decreased between 1989/1990 and 2003/2004, the decrease was much larger between 1989/1990 and 2016 (81 %) and 2003/2004 and 2016 (80 %). The decrease of the number of occupied grid cells here was 74 and 67 %, respectively. The number of breeding pairs per occupied grid cell in Recklinghausen district went down from 3.6 in 2003/2004 to 2.9 in 2016. The highest numbers of Lapwing pairs can be found in the wet meadow sites and nature reserves of ‘Rhader Wiesen’ and ‘Hervester Bruch’ in Dorsten and, with lower numbers, in specialised crops such as potato fields.
