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 Brent 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 restoration workshops, celebrating and sharing successes.

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

A series of river channel improvement were planned and delivered by the project. Thames21 officers and technical experts designed the schemes and secured the appropriate permissions from the Environment Agency and the Local Authorities. Much of the work has been carried out by volunteers with Thames21 support. In Quainton St Open Space, approximately 40m of hard engineering (wooden toe boarding) was removed to re-establishing natural banks and native plant communities. Eight large wood deflectors in a 500m longitudinal section were installed in the channel at in Burnt Oak Brook at Watling Park. The wood helps to re-energise low water flow patterns, improving habitat diversity and water quality during dry weather river flows. The logs were sourced from vegetation management work that took place at Quainton Street Open Space in January 2021.

Lessons learnt

Edit project overview to modify the lessons learnt.

The most significant challenge encountered was impact of the COVID-19 pandemic. The various lockdowns and meeting restrictions caused significant disruption to the planned community engagement and programme of volunteering activity. To mitigate this impact consultations were moved on to Zoom, social media, phone calls and emails. The classroom element of Thames21’s training courses were also move to on-line learning. This allowed the delivery of short and more flexible learning sessions that were supported by on-site, practical follow-up sessions. The new course structure, and the flexibility it offered was well received by volunteers.

As lockdown restrictions eased at the beginning of April 2021, Thames21 introduced a range of measures to allow the return of volunteering activity outside. This included: • Restricting the number of volunteers • Maintaining social distancing • Using extra hygiene procedures.
