The city of Portland wants to take the eco-roof concept to a new level by transforming building rooftops into actual wildlife habitats.
An international eco-roof expert says it can be done.
Wednesday, Dusty Gedge, president of the European Federation of Green-roof Associations, took a tour of some of Portland’s green roof-tops. Gedge says Portland is internationally known for its traditional eco-roofs which help reduce annual storm runoff by about 70 percent. But he says, with a few modifications, the green roofs also provide a home to wildlife like insects and birds.
"Roofs are a really good place to put these dry riverbed habitats. In summer it's really dry. In winter its quite wet and there's an ecology and nature that likes that, and roofs are the perfect place to do that," said Gedge.
