Full Title

National Mammal Atlas Project, online recording


Public sightings of mammals in Britain, submitted via an online recording form.


Mammals in Britain are critically under-recorded. To address this, The Mammal Society is compiling a National Mammal Atlas, the first for over 20 years, which will provide a detailed, up-to-date picture of mammal distribution and abundance across the British Isles. Records will build the atlas and provide vital information about mammals over the last 15 years, to help us make informed conservation decisions for mammals.
