Our latest in-house training course, run by Senior Ecologist Matt Cook (BSc (Hons) MSc MCIEEM), covered advanced bat survey techniques including using harp traps and acoustic lures.
After an initial training session on advanced bat surveys including Natural England class licensing back at the office, our terrestrial colleagues set off into the wilds of Derbyshire (or Carsington Water, as it is popularly called) for some field training in the use of harp-traps and acoustic lures.
This latest in-house training was a very informative and hands-on session, with five different species of bat caught under licence: Daubenton’s bat, whiskered bat, Brandt’s bat, brown long-eared bat and soprano pipistrelle. This allowed for close examination of common bat identification features such as size, ears and tragus, and the presence or absence of a post-calcarial lobe. Being able to identify a bat in the hand is important for our ecologists working with these protected species.
Beyond this, there are other benefits that ‘advanced’ survey techniques can bring to our clients and their projects; for example:
- These techniques can assess where key flight-lines and bat activity hotspots are on a site, ensuring that mitigation measures are evidence-based;
- They can remove many of the limitations of bat detectors, especially for quiet and cryptic species, by allowing identification of species, sex and an assessment of breeding status;
- They can often be more cost effective than ‘traditional’ alternatives, as they can reduce the amount of time needed in the field; and,
- Overall, important information about bat assemblages on a site can be gathered to help maintain the Favourable Conservation Status of these European Protected Species.
Additionally, development of these skills sets us apart from other consultancies, as very few have the in-house expertise to conduct these types of surveys.

About Matt Cook
Matt is an experienced bat ecologist, holding Class licenses 1 to 4, and with a range of survey and reporting experience. Matt’s passion for all things bat-related extends outside work, where he has been actively involved with local bat conservation groups since 2008. Matt has also been coordinating the Bat Conservation Trust National Nathusius’ Pipistrelle Project in the region for the last two years (read more about this here).
There are 17 resident breeding species of bat in the UK and all bats and their roosts are protected from harm and disturbance at all times by EU and UK law. Bats’ foraging habitats also receive some protection within the planning system. Bats can typically be surveyed between April and October using a variety of different survey methods.
