Between 2009 and 2010 Access Ecology carried out a range of surveys on behalf of Capita at MOD St Athans, nr Barry, South Wales.  These surveys were designed in two stages, aimed at determining bat activity levels in association with two very different groups of buildings in and around the active MOD base.

Capita  The first survey targeted actively used buildings on site, over 200 in total, with the aim of determining presence/absence for all buildings a swell as a site species inventory and the identification of key activity areas across site.  These surveys involved a large team of surveyors, carrying out nocturnal surveys (dusk, dawn and transect), supplemented by static recording at key points across the site. The data collected was used to inform the EIA for the site, and would, if works had gone ahead, provided the basis for mitigation needed in response to the loss of known roost sites.

The second project targeted over 30 disused Second World War personnel bunkers, scattered across the RAF base and in the surrounding countryside.  An innovative approach utilising Anabat remote recording bat detectors  was adopted, with each bunker being surveyed for a week at both the beginning and the end of the hibernation period, to ascertain if bats were using the sites as hibernation roosts. 

Anabats were chosen as access to many of the bunkers was not possible due to concerns over surveyor safety, with many bunkers unopened for many years.  Anabats could be positioned in such a way as to target openings in the bunker with the aim of recording any bats which may be active in and around the immediate vicinity.

Both surveys were completed on time and to the high standard that CAPITA expects, although ultimately the data remains unused due the suspension of the overall scheme.  Capita
