There is a Bryophyte distribution atlas for Staffordshire on the Staffordshire Ecological Record web site – staffs-ecology.org.uk . On the home page select Atlases from the main menu then Mosses and Liverworts from the dropdown. The atlas is searchable or you can select species from a dropdown. The maps have a first and latest record for the species. Although set up in 2006 the maps are updated with new records – sent in annually by the VCR.
