Nathusius’ pipistrelle presence is recorded with the aid of a broadband bat detector and audio recording device along walked transects around lakes in September.Sampling Description
Quality Control
The records have been verified through sonogram analysis by BCT staff. The dataset has been checked using NBN Record Cleaner.Method steps
- 1km transects are walked around lakes on up to two evenings in September. Continuous recordings are made from broadband bat detectors (mostly frequency division but sometimes time expansion and full spectrum sampling) and Nathusius’ pipistrelle calls are identified through post-survey sonogram analysis. Transects are divided into 10 walks interspersed with 10 four-minute stops so there are 20 sampling locations in total. TotalOccurences is the number of sampling points at which Nathusius’ pipistrelle presence was confirmed.
Taxonomic Coverages
Geographic Coverages
Lakes throughout the UK. The grid refs provided typically refer to a roughly central point on the lake rather than the exact location of bat records. Lake sites are selected by volunteers from a selection of nearby sites allocated by BCT staff and the survey does not provide complete coverage of the UK.
