Green Roofs Biodiversity (DC metro area)

As of November 2017, there are over 3.2 million square feet of green roofs in the DC area. That's over the size of 55 football fields! Help us inventory what species of plants, birds, insects and animals are thriving on our local green roofs. Please mark if your observation is "captive/cultivated", meaning it was planted intentionally. That will help us keep track of what's wild and not wild. menos ↑
