One of the key driving forces in establishing green roofs as an element in new urban development was the Black Redstart Action Plan for London, England. Since its inception, more than 15,000 square metres of green roofs have been planned. A rare breeding bird in London, the Black Redstart depends on old vacant lots and brown land. Since brown land has been targeted for the regeneration in the capital of the United Kingdom, the species is threatened within the city limits. It is expected that the installation of green roofs, while spurring economic regeneration, would also maintain biodiversity. Enhancing awareness of the benefits of green roofs was made easier through the Black Redstart Action Plan developed by the London Biodiversity Partnership. Various organizations and individuals throughout England have contacted the London Biodiversity Partnership since the launch of its web site. There are great hopes that green roof technology will become widely used in London (and other cities) as a result of the work performed by the London Biodiversity Partnership. 25 refs., 1 fig.
