The River Thames and its tributaries are home to a diverse array of wildlife, and ZSL is working to conserve and enhance this biodiverse ecosystem.

We're enlisting the help of citizen scientist volunteers in our vital conservation work. Whether you can help for a few hours, days or months, there are a number of projects for you to get involved with throughout the year. 

In 2024, ZSL’s aquatic citizen science projects will include:

2024 Outfall Safari Training Sessions

Please sign up to one of our training sessions below to learn how to carry out bankside surveys to identify and score polluting outfalls and to sign up to a section of river to survey. More information can be found on the Eventbrite links below.

River Rom and Beam

Edgware Brook/Deans Brook/Silk Stream

Beverley Brook




What we need from you

You will be fully trained so experience is not necessary and all equipment is provided. All you need is wellies, a willingness to learn from our experts and a bit of spare time to take part - we provide the rest! 

All volunteers must be over 18. If you are interested in any of these opportunities, please register here for more information:

Unable to volunteer, but keen to help?

If you are unable to volunteer but would still like to support our conservation work in the Thames, then you can still help conservation scientists to understand how seals use a popular haul-out site in the Thames Estuary. Instant Wild relies on members of the public to identify seals or other species captured in images from camera traps placed at Hamford Water.

If you see a dead or stranded marine mammal, please inform the Cetacean Strandings Investigation Programme.
