MIT Treepedia, using Google Street View to determine the extent of a city’s “green canopy” of trees, at least those visible along the roads. The website currently has a demo for 10 cities, but it seems that Green View Index comparison between a great many of the world’s cities is planned…

“we will continue to grow this database to span cities all over the globe. What does your green canopy look like?”

Sadly it seems that Birmingham is to cut its tree cover, literally. The city’s bosses plan to bow to terrorism and to cut down 25 old trees in the city centre. Obviously they’ve never read “The Scouring of the Shire” by a certain famous Brummie (who went to school just around the corner) nor learned its lessons.
