Hazel dormice are not the sort of mouse you would usually find inside a church – but you might find them in churchyards or cemeteries.
Dormice used to be widespread throughout much of Britain but their population has diminished significantly over the past century. Their distribution has been generally reduced to the southern parts of England and Wales due to changes in woodland management, farming practices, loss of hedgerows and the fragmentation of woodland. They are now a European Protected Species and a UK priority species. The People's Trust For Endangered Species coordinates a national monitoring programme for the species, and has reintroduced populations to some counties and run training courses in dormouse-friendly woodland and hedgerow management.
