This GIS dataset contains records of Lesser Horseshoe bats from known bat roosts. Records are presented in 1km resolution and contain a subset of attributes held in the NPWS Lesser horseshoe bat database. Some observations of non-targeted bat species have been recorded as well and are included in this dataset. Temporal coverage: 1978 to 2015.

The data is collected to determine and track changes to the national population of Lesser Horseshoe Bat to guide conservation efforts. This species is listed in Annex II and Annex IV of the EU Habitats Directive.

Provenance information	The data was collected from different types of count methods. Most data has been collected by NPWS rangers and staff, while the Vincent Wildlife Trust, independent ecologists and bat workers have also contributed to it. Data is to high quality. Records are added to the database on an ongoing basis. Count data are held in an MS Access database and were extracted and uploaded into the NPWS Species database. Checks of record locations against OSI Discovery series and Sixinch mapping were carried out prior to the upload and corrections were carried out where necessary in consultation with Bat Conservation Ireland. Recorder 6 validation rules applied. The records were then exported from the Species database as a polygon shapefile showing squares, with the side lengths of the squares corresponding to the precision in which the records were provided.
