Dedicated to protecting Washington’s forested parks, natural areas and communities.

A community-based solution focusing on stewardship of our urban forests & parks

Healthy forested parks and green spaces have the power to strengthen neighborhoods, provide safe access to nature and offer numerous benefits to our cities. A coordinated regional effort, Green City Partnerships, restores and cares for our urban parks. Working today to protect and enhance the many benefits these forests and natural areas provide.

tackling a growing problem

In 2004, the Green City Seattle Partnership began in response to many of our parks and natural areas being infested with invasive plants, preventing a new generation of trees from growing. Forterra and the City of Seattle recognized the opportunity to drive change and increase community benefit by working together to restore and maintain Seattle’s 2,500 acres of forested parkland. Developing a 20-Year Strategic Plan designed to get the job done.

a regional network

Building on the success of the Green Seattle Partnership, Forterra replicated and modified this model, building similar community-based stewardship programs around the region – creating a network of 14 Green Cities. Together they log over 115,000 volunteer hours at more than 1000 events each year.

green city partnership goals

  • Improve the quality of life, connections to nature, and enhance forest benefits in cities by restoring our forested parks and natural areas
  • Galvanize an informed and active community
  • Ensure long-term sustainable funding and community support

Restoring our urban parks requires a partnership and coordinated effort

These unique partnerships bring together thousands of community volunteers, local governments, businesses and Forterra to create a sustainable network of healthy forested parks and natural areas throughout the region. Green City Partnerships help urban communities in the Puget Sound region effectively steward their natural open spaces.
