## About

Forterra has worked on land and community in the Puget Sound region since 1989. Its Green Cities partnerships with Seattle, Tacoma and other cities put volunteers to work planting native trees and clearing invasive plants in urban forests and parks. Its events page lists volunteer days, and its grants support community restoration projects.
