- Bechstein's Bat Survey Project
Bat capture records collected using a harp trap and acoustic lure. This study aims to provide baseline data of the Bechstein's bat at a 10km resolution. The methodology, although targeted at Bechstein's bats also allows the collection of other bat species data at the same level.
- Field Survey
Numbers of bat passes counted in July with the aid of a bat detector along a roughly triangular route within a 1km square. Species presence records from this survey are included in this dataset.
- Hibernation Survey
Numbers of bats are counted at winter hibernation sites, and species identified.
- Nathusius' Pipistrelle Survey
Nathusius' pipistrelle presence is recorded with the aid of a broadband bat detector and audio recording device along walked transects around lakes in September.
- Natural England bat roost visit records from 2013 onwards
Records of bat roosts identified during visits by Natural England Volunteer Bat Roost Visitors (VBRVs) to dwellings, churches and public buildings. Zero counts are not included. This dataset is periodically updated with new records. Roost type has only been recorded in the dataset since April 2016.
- Roost Count
Surveyors count numbers of bats emerging from summer roosts at sunset on two evenings during the survey period. Surveyors choose their own roosts. A small number of counts are internal roost counts carried out under licence.
- The BCT/MTUK Bats & Roadside Mammals Survey
The distribution of bats and other mammals along roads in selected areas of England, Wales and Scotland.
- 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...
- Woodland Survey
Barbastelle presence in selected woodlands is recorded with the aid of a broadband bat detector and audio recording device along walked transects in July, August and September. This survey is funded by Natural England.
