Mission & History
Our Mission
To restore, enhance and protect the tree canopy of the nation’s capital.
History
In the late 19th century, the quantity and diversity of tree species located in Washington earned the District the moniker “City of Trees.” However by the 1970′s, the urban forest once envied by other world capitals had waned.
Betty Brown Casey, a longtime area resident, was deeply moved after reading the Washington Post article “Mayor Working to Keep It Green“ profiling the staggering decline of the District’s urban forest. Satellite imagery showed that the number of acres of heavy tree cover dropped up to 64 percent in some parts of the city in two decades because of disease, development and natural attrition.
In 2002, Mrs. Casey established Casey Trees to augment and support the work of the District government in reforestation and tree maintenance efforts. We have since planted more than 10,000 trees across Washington D.C., educated thousands on the importance of trees and worked with community groups, professionals and elected officials to protect existing trees and add new ones.
