Snipe survey of key sites in Britain in 2006

Quality Control

In order to verify records and validate the dataset, the data have been mapped and thoroughly checked. Geographical checks have included comparing the distribution with that shown in the published paper and ensuring that records with the same area name are located close to each other.

Method steps

1. Breeding snipe were surveyed in all fields at each site on three visits using standard methods of maximum counts of birds heard displaying to estimate abundance (O'Brien & Smith 1992). In order to verify records and validate the dataset, the data have been mapped and thoroughly checked. Geographical checks have included comparing the distribution with that shown in the published paper and ensuring that records with the same area name are located close to each other.

This survey covered 8 regions throughout England and Scotland. Historical data were collected in the early 1990s and the aim of the 2006 survey was to resurvey those sites that contained at least one drumming or chipping (displaying) snipe in the previous survey.

All records in this dataset are collated with summary 100m grid references of central grid reference points for sites surveyed
