Project summary

Edit project overview to modify the project summary.

The Restoring Brent Rivers and Communities project engaged local people in areas of high social deprivation in Barnet, Brent, Ealing and Harrow. Together we restored and improved sections of the river habitats with the aim to also increase community well-being. We increased access to the river and its paths, collaborating with local communities on practical river repair workshops, celebrating and sharing successes.

We aimed at the rewilding of sections of the river Brent by creating new wetlands, planting native aquatic plants, removing wooden toe-board and helping the river meander more naturally in its channel.
