All about the Living with Mammals survey

Why count urban mammals?

Towns and cities are home to a surprising number of wild mammals: from pygmy shrews and pipistrelle bats, the weight of a twenty-pence coin, to heavyweights, such as badgers and deer.

Green spaces, and the wildlife they support, are important: they provide food, clean air and water, and make us healthier and happier. They protect our homes from flooding, and trees reduce the effects of pollution and heat waves. Counting our wild neighbours, and knowing how numbers are changing, tells us about the health of these green spaces.

Whether in a garden, allotment, a local park or churchyard, telling us what you see builds a bigger picture of the wildlife on our doorstep. It can tell us when a species is in trouble. Without the help of thousands of wildlife watchers, we wouldn’t have known hedgehog numbers had fallen by a third in urban areas in less than 20 years and acted to help them. Read more about what we have found out in past surveys.

How do I take part?

Living with Mammals 2020 will run from 30th March to 28th June.

To take part later this spring 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.

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.

We’d love as many people to take part as possible whenever they are able to in this period, and every record counts! And don’t forget to share your sightings on our social media pages.

Please check back here at the end of March to take part online. If you need a printed pack (including full instructions, survey forms and a simple Spotting Wild Mammals guide) please email your name and postal address to or by call us on 020 7498 4533.

Any questions?

Just email our survey co-ordinator with your queries or call us on 020 7498 4533.
