Radio telemetary allows bats to be followed as surveyors track their movements from dusk to dawn.  It is a valuable method used to locate seasonal roosts, commuting routes and foraging areas.  Applied to the appropriate situation the information can be extremely valuable.  For larger schemes such as EIA (Environmental Impact Assessments) and where rare bats could be affected by a development it is often a required method of survey. 

Over the years Colleen and Paul have accumulated 1000 hours each of experience radio tracking a range of bat species including over 15 colonies of Bechstein's and barbastelle bats. Information gathered through this process has been integral to the planning and site design of schemes such as wind farms, new town developments and conservation management plans.
