Tree Report Card
The Tree Report Card, now in its seventh year, is the only independent tree and tree canopy assessment of a major U.S. city. It measures the quantity and quality of Washington D.C.’s trees and tree canopy and public and private efforts to expand and sustain it. Each spring on Arbor Day we release a new report that provides data on our urban forest and helps to raise awareness and encourage others to get involved with helping to expand and sustain the District’s trees.

Tree Space Design
Tree Space Design: Growing the Tree Out of the Box covers design recommendations to provide street trees with adequate soil volume while maintaining sufficient space for pedestrian circulation. The document includes a matrix of soil volume recommendations and root-friendly design methods intended for inclusion in design standards and use in individual projects, with the goal of yielding larger, healthier trees, and minimizing damage to paved surfaces.
