We choose to advocate because we believe in the idea that trees are more than the obvious benefits they provide and, because of this, they need someone to be their voice in government. At the very soul of our advocacy efforts lies the belief that our city is better because of trees and that all who live, work or visit the District need access to nature. Simply put, we speak for the trees, because they don’t have the voice to speak for themselves.
