Forterra has official partnerships with the cities of
Everett,
Kent,
Kirkland,
Redmond, Seattle, and Tacoma in leading stewardship projects at city parks and urban forests. Public volunteers and volunteer Forest Stewards work with cities and Cascade Land Conservancy in implementing 20 year plans to protect urban forests from invasive plants. On November 2, 2011, Cascade Land Conservancy officially changed the organization's name to 'Forterra' (meaning 'for the earth') in order to reflect the organization's changing goals. As Washington State's largest conservation and stewardship organization, the 'Cascade' in the name did not reflect the statewide work area. 'Land Conservancy' likewise no longer embodied the purpose of the organization. == Green Seattle Partnership ==
