The survey begins!

Carrying out the soil surveyThe soil and earthworm survey has begun. You can now take part in one of the nation’s biggest public nature surveys and learn all about earthworms and the world they live in.

Your results will help scientists build a national record of earthworm populations and soil types across England.

Everything you need to take part, including full instructions and an earthworm identification key, can be found on the website.

Once you’ve completed the survey, upload your findings onto the OPAL website and you'll be able to view your contribution on our interactive map.

If you want to learn a bit more about earthworms before you head out into the field, check out our online earthworm guide, which includes profiles on all the earthworms being recorded in the survey.

We hope you enjoy taking part in this survey.
