Bat Survey Plymouth

What is a bat survey?


Bat ecological surveys detect when a bat is present or the likely absence of bats within the development area so that planning applications and the development process can proceed. If the survey for planning licence applications finds that there is evidence of bats in close proximity to a site, bat mitigation measures and compensation measures must be undertaken before any development work is permitted to proceed.

Bat activity in Plymouth

The active season for bats in Plymouth is at its peak during the summer months. Therefore, this is the best time of year to carry out survey work to determine the presence of roosting bats.

The many species of bat based in Southwest are Brown Long-eared bats, Common Pipistrelle bats, Natterer’s bats, Daubenton’s bats, Whiskered and Horseshoe bats.


Bat survey Plymouth: Types of bat survey

There are two types of bat surveys which can help you to discover which bat species are present, if any. The first is a preliminary roost assessment which involves an Ecology Consultant carrying out a site visit. Bat surveyors will carry out both an internal and external inspection of the building, looking for evidence of roosting bats, including insect feeding remains as well as bat droppings to produce a bat report.

The second type are nocturnal bat emergence surveys involve surveyors using bat detectors in an area of conservation in order to record and analyse bat calls. When the surveyors have completed a bat survey, they will operate either when bats are present and leaving bat roosts to forage (dusk emergence surveys) or when the bats return to their roosts (emergence and re-entry surveys) to determine the number of bats.
