Join our Living with Mammals survey

Home // Get involved // Surveys // In your garden // Join our Living with Mammals survey

Wherever we live in the UK, we share the green spaces around our homes and places of work with wild species.  By carefully identifying and counting the mammals that live in and around built up land, we can begin to understand – and encourage – the biodiversity on our doorstep.

Understanding how the wildlife in our towns and cities is faring is essential if we’re going to improve the lot of our wild neighbours and that of ourselves too.

Take part in Living with Mammals next spring

The survey runs every April till June, so has finished for this year. All you need to do is keep an eye out each week for eight or more of the 13 weeks (they needn’t be all together) , recording the mammals you see and any signs they might leave behind, such as droppings or footprints.

Revisit this page next spring to take part online 

or contact us for postal survey pack (including full instructions, survey forms and a Spotting Wild Mammals guide) by emailing or calling us on 020 7498 4533.

To take part, you can chose any site – a garden or allotment, a local park or other green space – that’s convenient to spend a little time at each week. The site must be within 200 metres of a building. Any questions? Just email with your queries or call us on 020 7498 4533.
