Post-London Rivers Week 2026: Learning from nature – working with trees to improve rivers [FULLY BOOKED]

Join Dr Helen Moggridge on a post-London Rivers Week guided walk along the Old Lea, learning how we can use trees in rivers to return them to a healthier and more natural state.

Please join us for a guided walk along the Old Lea to learn about the essential role of trees in rivers and to demonstrate how we can use this understanding to restore our rivers to a more natural state. On this walk, you will discover the vital role that trees play in shaping our rivers and supporting wildlife (hopefully with some wildlife spots along the way!). The walk will demonstrate some of the natural features along the Old Lea and showcase some recent river restoration works.

The walk is aimed at anybody interested in their local river or with a general interest in nature and the environment.

The walk will be led by Dr Helen Moggridge. Helen is a river scientist, environmental consultant and former university lecturer, with academic research interests in river processes (especially trees in rivers) and river restoration.

We will walk the Old Lea around Hackney Marshes. The walk will be around 1.5km and will last for 1.5 hours, but please join for as long or as far as you wish! The walk will be fully outdoors, so please dress for the weather and bring some water and binoculars (if you have them). Strong footwear is recommended.

This walk is the second in a series of nature walks organised by the Rewilding the Old Lea project, supported by The Mayor of London and Hackney Council.
