We plant, care for, and protect trees in the national capital region.
In 2001, Washington, DC’s tree canopy covered just 35% of the city. Over the years, we’ve made significant progress, planting more than 60,000 trees and setting an ambitious goal: to achieve 40% canopy by 2032. Through innovative programs and community partnerships, we’re working tirelessly to create a greener, healthier DC for generations to come.
