South East Rivers Trust (& the Wandle Trust)

Thames Catchment Community Eels Project is a partnership, led by Thames Rivers Trust, with Action for the River Kennet, South East Rivers Trust and Thames21.  We are working together to aid the long-term survival of the European eel.  Through new citizen science monitoring, we will be collecting and analysing robust data, which can then be used to make strategic decisions for future eel recovery projects. 

Our aim is to raise the profile of this Critically Endangered fish through education and engagement with local schools and communities.

Elver Migration Monitoring

We’re going to be working with an amazing bunch of volunteers to monitor the migration of young eels (elvers) on the River Ember, a side branch of the River Mole.

Recruitment of young eels has fallen significantly over the last 40 years so this monitoring is incredibly important to help them survive and thrive. The data collected at this site feeds into a project spanning the Thames, coordinated by ZSL. It provides essential information which helps prioritise and plan work across London and beyond to help these endangered creatures.

Between April and September our team of volunteers will be:

  • Checking the eel trap regularly
  • Counting, measuring and releasing any eels found
  • Uploading records to the ZSL website.

This gives us data on the number of young joining the adult population and can highlight the impact of barriers, one of the principle threats to eels in freshwater. No previous experience necessary and all equipment is provided but you must be over 16 to participate!

Check out the video below to see what’s involved. Contact for more information on how to take part.



Education Sessions

The South East Rivers Trust is offering a limited number of free assemblies and lessons as part of The Thames Catchment Community Eels Project. We will be bringing the European eel and the local river to classrooms in the River Mole area.

We are now taking bookings for the summer term. Sessions are linked to ‘Living things and their habitats’ and provide a valuable contribution to a range of topics such as Rivers or Climate Change. 

It’s fun and it’s free!

Community Talks and Guided Walks

 The South East Rivers Trust is also looking to deliver a number of guided walks and talks with local community groups in the Mole catchment.

We will introduce the species and talk about its incredible life cycle, before covering some of the threats it faces and what’s being done to help it. It is a great opportunity to raise awareness about the plight of the eel which is an incredibly fascinating creature.

If you’d like us to come and talk to your community group or run a guided walk with you, please email
