Barbastelle (Barbastella barbastellus) Bat Distribution Model (2011)
The purpose of this data capture was to use a multidisciplinary approach to fill current knowledge gaps in the ecology and conservation requirements of a rare bat, the barbastelle (Barbastella barbastellus). Spatial modelling was used to evaluate the environmental parameters that dictate where the species is able to persist in the UK and to identify areas of high conservation value. The purpose of this data capture for Countryside Council for Wales was to assess and predict the distribution of the species around Wales. The models were created and used my Matthew Zeale, a PhD student at the time. The PhD findings from the models indicated that B. barbastellus is highly dependent on large areas of native mature woodland and is limited in its distribution predominantly by summer climate, although a number of other environmental factors also appear to be important. The data collation and survey undertaken by experienced bat biologist. The results were later submitted as part of a PhD Thesis.

Matthew Zeale (PhD student from Bristol University) investigated the value of using species distribution modelling (Maxent) for facilitating the identification of Barbastella barbastellus maternity colonies within woodland areas. Two models were developed. Firstly B. barbastellus species distribution was modelled at the UK-wide scale to identify suitable regions in which to conduct searches for maternity colonies. A second model was developed to predict the species' presence or absence within woodlands in a study area in south-west Wales. The predictions made by the latter model were ground-validated by surveying 30 woodlands for B. barbastellus presence using acoustic monitoring and trapping methods. Analysis of the model's performance showed that it predicted B. barbastellus presence/absence to a high degree of accuracy.
