OPAL Soil and Earthworm Survey

The OPAL Soil and Earthworm Survey needs citizen scientists to collect and separate earthworms and to examine the surrounding soil properties.

Earthworms are extremely important and play a vital role in recycling plant nutrients and aerating the soil. By taking part in this survey you’ll help improve our knowledge of earthworms and the soils they live in.

Everybody can take part in the soil and earthworm survey - all ages and abilities. It’s simple, fun and you’ll be contributing towards valuable research.

This is one of five OPAL surveys across England to learn more about the state of the environment. Anyone can get involved. The studies are open to all ages and abilities, and your contribution will be important in helping scientists build up a picture of England’s natural environment.
