— The city of Portland has grand aspirations of taking the green roof concept to a new level by turning the vegetative structures into wildlife habitats, according to KGW-TV
Though green roofs undoubtedly are more welcoming to wildlife than conventional roofs, experts say that, with minor modifications to current green roof models, Portland rooftops can be havens to birds, insects and other living organisms, the story stated.
Dusty Gedge, president of the European Federation of Green Roof Associations
, said: "Roofs are a really good place to put these dry riverbed habitats. In summer, it''s really dry. In winter, it''s quite wet and there''s an ecology and nature that likes that, and roofs are the perfect place to do that."

Director Bob Sallinger envisions one day transforming the warehouse rooftops that line the Columbia Corridor
into acres and acres of biodeverse rooftop grasslands, the story noted.
The city of Portland has set a goal of achieving 49 total acres of green roofs by 2013 and, to entice residents to buy into the plan, they are offering credits of up to $5 per square foot to any home or business owner that builds one, the story added.
