Population estimates and changes in abundance of breeding waders in Northern Ireland up to 2013

Capsule The third survey of breeding waders in Northern Ireland showed large declines in the abundance of Eurasian Curlew, Northern Lapwing and Common Snipe since 1987.Aims To estimate the size of the breeding populations of selected breeding wader species in Northern Ireland in 2013 and population changes since previous surveys in 1987 and 1999.Methods Complete surveys of all potentially suitable breeding habitats were undertaken in randomly selected 2 km squares in each of 146 land-dominated 10 km squares across Northern Ireland. Square selection and a two-visit field method replicated previous surveys conducted in 1987 and 1999.Results Northern Ireland breeding populations of Eurasian Curlew, Northern Lapwing and Common Snipe were estimated to be 526 (±95% CI: 252–783), 860 (277–1545) and 1123 pairs (527–1782), respectively. These estimates represent significant declines in abundance of 82%, 89% and 78% respectively since 1987.Conclusion Breeding populations of Eurasian Curlew, Northern Lapwing and Com...
