National Mammal Week, by the Mammal Society, is an annual celebration of Britain’s wild mammals, and the people working to monitor, protect and restore populations of these vital species.
Mammals are all around us, playing a vital part in balanced and resilient ecosystems, but are usually out of sight and out of mind due to their secretive and often nocturnal lifestyles. As a result, mammals require records for scientists and conservationists seeking to ensure their future. You can help with that!
By taking part in the Mammal Discovery Challenge throughout National Mammal Week you’ll help collect vital data on mammal populations, while having fun and learning about the fascinating wildlife on your doorstep.
How to get involved in the Mammal Discovery Challenge
There are loads of ways to discover the mammals in your local landscape - anyone can be a citizen scientist! Register your interest in taking part in the challenge to receive information and inspiration leading up to, and throughout, National Mammal Week.
Use free toolkits to detect and record mammals in your garden, schoolground or local greenspace. Look out for the Society's free online training events in April to prepare for a busy week of mammal recording!
- Learn how to spot, ID and record the mammals visiting your patch
- Recognise and record the signs of mammals - tracks, burrows, feeding signs and droppings
- Make a footprint tunnel and use our guide to detect which mammals have been visiting
- Use trail cameras to capture your nocturnal visitors going about their business
Share your discoveries via the Mammal Society's free Mammal Mapper app or by emailing them to [email protected].
