The document discusses the mission and goals of restoring, enhancing, and protecting the tree canopy of Washington D.C. It outlines Casey Trees' efforts through multiple rounds of a "Tree Report Card" to track progress towards a goal of 40% tree canopy coverage by 2032. The report card helped raise awareness and engagement from citizens and politicians, and impacted legislation to better protect and care for the city's trees. While an imperfect measure, the report card serves as a guide to track general progress over the long term towards the identified canopy coverage goal.
