Our Story

Casey Trees is a Washington D.C. based nonprofit, established in 2002, to restore, enhance and protect the tree canopy of our nation’s capital.

Trees do more than keep us cool, manage stormwater, and control pollution. They encourage outdoor activity, calm our nerves, and make our homes and streets beautiful. In fact, they enrich our lives in ways we are just beginning to understand.

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.

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 in 2002 to gain back the trees that it had lost.

By working with public and private 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.
