Mammal fact files

Click on the animal names below the pictures to learn more about the mammals that live in the United Kingdom.

Estimates of population sizes are taken from the Mammal Society’s 2018  report, ‘A Review of the Population and Conservation Status of British Mammals: Technical Summary’. There are eleven mammal species (either native or naturalised) that are at risk of extinction in Britain in the near future (within the next decade or three generations). These ‘Threatened’ species  are classified as: Critically Endangered (CR), Endangered (EN), and Vulnerable (VU). Four others are ‘Near Threatened’ (NT).
