Acoustic lures and harp traps expand our bat survey skills
Last week, as part of our ongoing CPD and survey innovation commitments, two of our Natural England licensed bat ecologists attended an advanced bat survey techniques training course in Sussex at the National Trust Slindon Estate.
Uniquely, this course is run via the not-for-profit Bat Conservation and Research Unit (BatCRU); something that particularly appeals to our conservation-minded ecologists. In essence, the trainees taking part in the course are also acting as researchers and funds generated from the training courses (alongside a grant from SITA) enable the BatCRU to undertake The West Sussex Bat Project with support from the National Trust.
The course has been running since 2013 and the overall aim is to use the data acquired from all the research to apply for a grant for large-scale bat habitat improvements in West Sussex, particularly for rare Annex II bat species (such as the barbastelle bats shown below) from the EU LIFE+ fund.

What bat survey skills did we learn?
For Diana Clark, Senior Ecologist at Baker Consultants and licensed at level 2 by Natural England, this was her first time on the week-long course. An experienced bat ecologist with many years experience as a consultant (and with local bat groups), Diana was keen to learn more about the use of advanced survey techniques such as mist nets, harp traps, acoustic lures, professional night-vision equipment and radio-tagging and -tracking, as well as research techniques such as ringing. Suffice to say Diana now has an excellent understanding of these methods, and when best to use them, and was lucky enough to get up close and personal with a couple of new (to her) bat species.
For Matt Cook, Senior Ecologist at Baker Consultants, this was actually his third time. Matt already holds a Natural England level 3 and 4 class licence to survey for bats using the above techniques, but is always keen to advance his knowledge further and study bat ecology in general; particularly when he can support the research being undertaken by BatCRU.

All bats and their roosts are protected from harm and disturbance at all times by EU and UK law and bats’ foraging habitats also receive some protection within the planning system.
For more information on how our advanced bat survey techniques can benefit your project or if you have any queries relating to bats and your project, please contact Matt Cook, Senior Ecologist.
The course Matt and Diana attended was devised and run by Daniel Whitby, Director of AEWC Ltd with additional support from Daniel Hargreaves of Trinibats. Both Daniel W and Daniel H are technical advisors to the Bat Conservation Trust and Natural England.
