 In 2009 a detailed study by The Bat Conservation Trust of 10 counties took place to determine the range of the Bechstein's bat and in 2010 a lactating female Bechstein's was discovered in Grafton Wood, an Ancient Wood originally part of the Forest of Feckenham and jointly owned by the Worcestershire Wildlife Trust and Butterfly Conservation, suggesting that there was a breeding colony in the wood or close by.The following year Bechstein's were again found at Grafton Wood and also at Trench Wood, also in Worcestershire .The People's Trust for Endangered Species are funding further research work at Grafton Wood.
