There are 63 species of mammal recorded in Cornwall  which include 5 endemic species found on the

Isles of Scilly such as the rare Lesser White-toother Shrew (Crocidura suaveolens), known locally as the Scilly Shrew. 

ERCCIS has a long history working with local recording groups like the Cornwall Mammal Group, the Cornwall Bat Group, and the Marine Strandings Network to encourage recording at local community level and raise awareness of mammals found in Cornwall. 


The Mammals of Cornwall and the Isles of Scilly atlas published in 2013 is an excellent guide to any recorder or mammal enthusiast. With 56 species accounts (including 12 of the more commonly recorded marine mammals) with distribution maps, descriptions, tracks and survey, ecology and biology accounts this guide has so much to offer experts and novises alike.
