Earthworm Sampling Day

Biological Recording Company logo

Join like-minded people with an interest in recording wildlife observations for a day surveying earthworms. The specimens collected will help us to build up a a library of images for the Earthworm Image Recognition Project and generate earthworm species list for the site. All records will be added to the National Earthworm Recording Scheme database. Sampling earthworms involves conducting microhabitat searches and hand-sorting soil pit samples to collect specimens for identification by our trained earthworm recorders at a later date.

Participants will also be asked to take photographs of the earthworms that they collect and submit these to the Earthworm Image Recognition Project - an exciting collaboration with the UK Centre for Ecology & Hydrology to create and test an app that will attempt to identify earthworms using AI.

What will the day involve?

  • Practical experience using a variety of methods to survey and sample earthworms.
  • Practical experience in collecting and preserving earthworm specimens.
  • Contributing to an innovative project involving smartphone photography and AI
  • A chance to meet fellow like-minded people from a range of different disciplines.

Recording the UK's earthworms

All records generated through this event will be submitted to iRecord in order to share our findings with the site managers, the Local Environmental Record Centre and the National Earthworm Recording Scheme.

The photos generated will be shared with the UK Centre for Ecology & Hydrology and used to train an image recognition AI to assist farmers with earthworm identification.


This event will take place in at Woodhouse Farm near Marrick in North Yorkshire (DL11 7LD).

We'll be outside for the whole day so please bring suitable clothing for all types of weather and please bring your lunch and any snacks you will require with you on the day.

This event is delivered by the Biological Recording Company on behalf of Tees-Swale: Naturally Connected and is endorsed by the Earthworm Society of Britain

Tees-Swale: Naturally Connected is led by the North Pennines AONB Partnership and the Yorkshire Dales National Park Authority and is supported by the National Lottery Heritage Fund.
