Experienced Bat Survey Experts  

Our use of the latest advances in bat survey equipment allows us to identify bat species both in the field and during post-survey data analysis. 

We use GPS-enabled bat detectors for transect surveys which allows us to successfully map bats during walked activity surveys on Google Earth Pro, and GIS software. We use a range of thermal imagery and infra-red data captures across our roost surveys having invested heavily to ensure we are at the forefront of the field. 

Our Natural England, Scottish Natural Heritage, and Natural Resources Wales licensed bat ecologists have extensive experience in completing European Protected Species Mitigation Licence (EPSM) applications for a range of development types and scales involving a range of bat species throughout the UK. 

Our ecologists undertake initial daytime assessments as part of our bat survey of buildings and trees. This helps us assess their potential to support roosting bats. We then follow this up with pragmatic yet robust advice to fully investigate the situation. 

Our Ecologists are also available to deliver on site toolbox talks, supervision of tree felling, demolition, and/or building works under licence.

Daubenton's Bat (Myotis daubentonii): Named after the French naturalist Louis-Jean-Marie Daubenton, this bat is known for its habit of hunting over water, using its large feet to scoop up insects from the surface. It is found near rivers, canals, and lakes.

Common Noctule (Nyctalus noctula): The common noctule is one of the largest bat species in the UK, with a wingspan of up to 45cm. It prefers open habitats such as woodlands, parklands, and farmland, and is known for its distinctive fluttering flight pattern.
