The humble earthworm is valued by farmers and gardeners alike for its contribution to healthy soils. But if you dig two holes in a field, you can find earthworms in the soil from one hole but not the other. What controls the distribution of earthworms has remained a poorly understood question since the time of Darwin.
In this talk we’ll discuss whether finding earthworms in soil is a good indicator of a healthy soil, what factors control the presence of earthworms in soil and how many holes you have to dig to find an earthworm.
FSC Natural History Live webinars are free online learning experiences for adults, comprising of a 30-40 minute talk from a guest speaker, followed by a question and answer session. We host them on Zoom and we will send out joining instructions on the day of the event.

Tutor: Mark Hodson
Mark Hodson began his research career studying how magma chambers solidified below volcanoes in Greenland millions of years ago but his need for a job lead him into the world of soils. Research on cleaning up metal contaminated soils introduced him to the use of earthworms as indicators of “healthy soil” and he has been investigating various aspects of earthworm ecology ever since. @MarkEHodson

Bursaries and Subsidies
FSC BioLinks is an exciting project for FSC in the South East and West Midlands, bringing together existing volunteers with skills in biological recording and identification, and new volunteers.
This project provides subsidised training courses, learning opportunities and digital tools focussed on invertebrate identification for anyone involved or interested in biological recording, to build and strengthen the community.
Invertebrates provide us with many useful ecosystem services, like pollination and decomposition, which we cannot survive without but their numbers are declining. Few people know how to identify or record invertebrates meaning there is a lack of data
We are delighted to have been awarded a grant of £1.23 million from the National Lottery Heritage Fund for this project.
