At Casey Trees our mission is to restore, enhance and protect the tree canopy of our nation’s capital.
Established in 2002, Casey Trees is an urban forestry nonprofit that connects people to trees and inspires communities to come together and take responsibility for the long term health of the urban environment. By working with volunteers and partners city-wide we plant, maintain, monitor and advocate for the trees of Washington D.C. to ensure that they stay healthy and abundant for generations to come.
Estimated at 50 percent in 1950, D.C.’s tree canopy declined to 35 percent in 2011. A Washington Post article chronicling this decline encouraged Betty Brown Casey, a longtime area resident, to establish Casey Trees to gain back the trees that it had lost.
The legacy of D.C.’s trees began in 1790 when President George Washington, an avid tree lover, hired Pierre L’Enfant to design its layout. L’Enfant’s plan envisioned a capital city graced by grand tree-lined boulevards and parks, and many of those elements may still be seen today. But, like all visionary public space plans, the hard part is the long-term commitment required ensure that it lives on.
Trees keep us cool, manage stormwater, and control pollution. They encourage outdoor activity, calm our nerves, and make our homes and streets beautiful. If you’re passionate about trees, sign up for a class, help us plant some trees in your neighborhood, or take advantage of the many volunteer opportunities we have available — it’s a lot of fun and a great way to meet people in The City of Trees.
