Nocturnal Bat Surveys
Nocturnal surveys are performed by at least two bat surveyors to monitor for presence of bats emerging, or returning to,
the site. Nocturnal surveys also provide information about the level of bat activity around the property being surveyed. A minimum of two nocturnal
surveys have to be undertaken.
Bat detectors (echolocation receivers) and recording equipment are used to monitor and record bat activity. This allows later analysis to confirm the
bat species and their numbers.
Nocturnal surveys are only conducted during weather conditions that are likely to support bat presence. Advanced planning is necessary to ensure that
surveys can be undertaken within the development’s scheduled timescale.
Nocturnal surveys are undertaken from late April to early October.
If a bat roost is found then a licence may be required from Natural England in order for development work to proceed.
NKM Associates provides nationwide bat worker services and operates predominantly in Gloucestershire, Warwickshire, Worcestershire, Oxfordshire,
Herefordshire, West Midlands and Staffordshire.
