First records of the greater white-toothed shrew Crocidura russula from Great Britain.

Abstract

The presence of the greater white-toothed shrew has been confirmed from two sites in the borough of Sunderland in North East England. These represent the first records of the species in Great Britain. Dated photographic evidence indicates that the species has been established in that area since at least 2015. Research is required to ascertain the extent of its current distribution in Great Britain and its impacts on native small mammals and ecosystems more generally.
