Mission 2 - Worm detective

What's living below ground?  Earthworms and other ground-dwelling invertebrates are an essential part of the diet of many birds and mammals. We need you to take part in an experiment to tell us what’s living beneath the soil in your garden so we know how much of this vital food is available to other wildlife.

Some of the birds and mammals that rely on soil invertebrates to form the bulk of their diet are under threat. In particular, both song thrush and hedgehog numbers have halved in the last few decades. We hope to find out how the quantity of invertebrates varies from garden to garden around the UK, so we understand out how abundant this vital food source is in different garden habitats.
