Waterway Survey

Numbers of Daubenton's bat passes counted with the aid of a bat detector along a 1km stretch of waterway in August. Species presence records from this survey are included in this dataset. GB data are from BCT's National Bat Monitoring Programme core-funded by the Joint Nature Conservation Committee. Northern Ireland records are from the All-Ireland Waterway Survey run by Bat Conservation Ireland and funded in NI by the Northern Ireland Environment Agency.
