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 through April, May and June each year. To take part, all you have to do is record the mammals that you see each week 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 a printed pack (including full instructions, survey forms and a Spotting Wild Mammals guide) by emailing your name and postal address to or by calling us on 020 7498 4533.

You can chose any green space to survey, whether a garden, an allotment, a local park or other area that’s convenient to spend a little time at each week, but the site must be within 200 metres of a building.Any questions? Just email with your queries or call us on 020 7498 4533.
