Discover what lies beneath your lawn

It is one of the world’s most precious natural resources and is vital for growing the food that we depend on for survival.

But how much do you know about the soils beneath your feet and the creatures that make their home there?

As milder temperatures begin to arrive, it’s the perfect time to discover the world beneath your lawn by taking part in the OPAL soil and earthworm survey.


How do your earthworm results compare?

A new feature on our website will show you how your soil and earthworm survey results compare to other sites across the country.

Our live results map now tallies up the number of earthworms you’ve counted and plots them against surveys submitted by other people.


OPAL releases new earthworm key

Help our scientists by identifying the earthworms in your garden or school playing field with our new, simple guide.

The free guide covers the seven most common species of earthworms in British lawns and recreation fields, helping you put names to the species you might find in your own back garden.


Help us fill soil survey gaps

A big thank you to to everyone who has submitted results for the soil and earthworm survey. Nearly 4,000 surveys so far!

Your results have helped us understand more about soil properties and the distribution of earthworms across the country.

However, there are some areas of the country where we have received very few surveys (see the map below), so we'd love your help to fill these 'gaps'.


Just can't get enough of those worms...

A brand new wildife group has just started up, dedicated to the humble earthworm. The Earthworm Society of Britain held a launch event in Hyde Park, London, testing all the different methods of worm charming.  You can see from the photo above that some worm charmers start very young indeed! As a World Worm Charming Championship competitor, of course I wouldn't miss this for the world!

We were testing 5 different methods of worm charming:
