An innovative 200 square metre green wall on a central London Tube station wall designed to trap pollution on one of London’s busiest roads, was unveiled today.
The visually stunning green wall has taken just a month to install and, as well as having practical environmental benefits, is an attractive leafy addition to Marylebone Road.
It features a total of 15 plant varieties crafted into a multi-coloured and patterned design. Studies across Europe and the USA have shown the potential of vegetation, including trees and plants, to trap PM10. The air quality benefits of this wall will be monitored by scientists from Imperial College London.
Tree Exchange is part of a new initiative encouraging Londoners to gather seeds to grow new trees – for their own patch or community, or to offer to other neighbourhoods who need them.
Simply fill in the online form to list your spare trees or place a trees wanted advert if you need trees for a community project. Londoners can then search the Tree Exchange using the search function or by filtering the Tree Exchange by London borough.
To fill in the 'Give Away' or 'Wanted' form, simply click on the 'POST AN AD' button. Please note that it can take up to 2 working days for your advert to appear on the Tree Exchange.
Tree Exchange is a free-tree community initiative and no money should be involved in the exchange of trees.
