Pittsburgh’s Urban Tree Canopy in National Geographic

Pretty cool, from National Geographic. Pittsburgh is highlighted with some other big player cities.

42% tree cover tops the list of the 9 featured cities.

A significant portion of hillside around the world’s former steel capital has variously been mined, logged, and built upon. But with the passage of time, much of it has been naturally reforested. This new-growth forest and the city’s four large parks make for a patchy canopy, so local environmental organizations have enlisted volunteers to plant 20,000 trees in recent years. The expanded urban forest removes 532 tons of air pollution every year.
