Peter Shute wrote: "By "green roofs", do you mean green in colour, or roofs
with solar panels on them?" in response to Jim Tate's e-mailon the "Brisbane
River terns" chain.Jim will undoubtedly reply for himself, but just for the
wider readership it may be of interest to highlight the interest in the
utilisation of urban rooftops for augmenting the natural environment (or
countering negative impacts on the environment) in Britain and Europe.
Undoubtedly this is because of the much greater percentage of urbanised land.
It has spawned a movement variously known as the "greenroof movement" - (or the
related "brownroof movement") which aims to persuading the developers of urban
buildings to incorporate natural vegetation and soils/gravels on the rooftops
of new buildings. I have placed to links below (or phrases to enter into Google
or other search machines) - one UK focussed and the other a European focussed
link. The photo image which appears on the Home page of the first link i
s of a modest demonstration of the philosophy which is a shelter built in a
demonstration sustainable garden built at the London Wetland Centre (where I
act as a volunteer guide). The two sites show many images of buildings with
green roof treatment.One of the most spectacular examples that I have seen is
the roof treatment of the hotel at Uluru, although that was obviously intended
for landscape blending purposes - but with terrific plantings of desert flowers
amd shrubs (or at least it was n the 80s). The links:
