Earthworm Sampling Day

There are 33 species of earthworm living freely in soils in the UK. They are vital to the economic health of our country, as they are crucial for soil health, food production, waste decomposition and even flood mitigation. Despite their importance, we know so little aboout their distributions.

Come along for a hands-on day of earthworm surveying with fellow nature enthusiasts. You'll help search for and collect earthworm specimens, contributing to generating valuable data to build a species list for the site. Our survey methods include exploring different microhabitats and hand-sorting soil samples to gather specimens, which will later be identified by trained earthworm recorders. All records will be added to the National Earthworm Recording Scheme, helping to expand our understanding of these important soil creatures. No experience is necessary—just bring your curiosity and a keen eye for wildlife.

• Fieldwork experience in undertaking soil pit sampling surveys to assess soil-dwelling earthworm species.
• Hands-on experience of undertaking microhabitat searches to find above-ground earthworm species.
• Practical experience in collecting and preserving earthworm specimens.
• Recording environmental and ecological data required for the generation of earthworm species occurrence data.
• A chance to meet fellow like-minded people from a range of different disciplines.

• This event is aimed at adults only. 
• It’s free to attend and no previous experience is required as earthworm sampling methods will be taught to all attendees on the day. 
• Attendance is free, but booking is essential as spaces are limited.
• This event will involve the collection, preservation and killing of earthworm specimens for identification purposes.
• 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.
• All records collected will be submitted to iRecord in order to share our findings with the site managers, Local Environmental Record Centre and the National Earthworm Recording Scheme.

Welsh Harp (also known as The Welsh Harp, Welsh Harp Open Space or alternatively, Brent Reservoir) is a Site of Special Scientific Interest (SSSI) and Local Nature Reserve (LNR) in North London, on the boundary of the boroughs of Brent and Barnet. Originally built in the 1830s to provide water for London’s canals, the site comprises 170 acres of open water, marshes, woodland and grassland. It is recognised as one of the most important bird breeding areas in Southern England. The varied habitats also support a range of other wildlife. Find out more here:
