The Great West Hedge

The Great West Hedge was an innovative and challenging proposal to plant a protective and attractive hedge along the A4/Great West Way to filter out some of the pollution for pedestrians, cyclists, residents and schoolchildren. Providing more green, a wildlife corridor, and improved street scene, and potentially filtering out some of the road noise.

Run as a Living Laboratory it would provide a London-based proof of the benefits of green infrastructure along roads for the improvement of air quality.

It would have run from the end of the elevated section of the M4 at Chiswick through to the Hammersmith Flyover. The hedge would have run along both sides of the A4 from Chiswick roundabout to the Hammersmith flyover. Forty local groups (residents’ associations, churches, schools, nurseries) were involved.

Unfortunately, after several years in discussion with TfL, much of it extremely encouraging, it became clear that TfLwas not interested in taking this project forward.

Abundance planted 12 trees (11 of which have survived) and as a consolation prize to the community groups, TfL planted 20 trees (all of which died) and promised to sow wildflower verges, none of which have been sown to date.

What does it look like?

We want the Great West Hedge to be a Living Laboratory, where the local community can work in partnership with public bodies and organisations in helping develop and prove in a real life environment the benefits of hedges for reducing urban pollution as shown by research.
