how it works
- Get the Big Worm Dig survey booklet here. You can download it right now or request it to arrive in the post (limited supply, so first come, first served).
- Do your survey and jot the results down in your booklet. It should only take about 20 minutes or so.
- Upload your results and we'll pass them on to our earthworm experts for scientific analysis later in the year.
what will the survey tell us?
This survey will identify which of the UK's 10 most common earthworm species you have found. Very little is known about the distribution of British earthworm species, so the results you send in will all go towards improving our ecological knowledge of these hugely important creatures.
eg. Tiger worms
eg. Marsh worm, Square-tailed worm, Gilt‑tail worm
eg. Blue-grey worm, Grey worm, Green worm, Rosy-tip worm
eg. Lob worm, Black-headed worm
