Green Cities Research Alliance
Urban Natural Resources Stewardship

Sustainable cities through science, policy, and action


More than 80 percent of the Pacific Northwest region’s population lives in urbanized areas. Green Cities Research Alliance is the result of collaboration between the USDA Forest Service and the University of Washington. Program studies focus on the social and environmental situations where people live, learn, work, and play. The purpose of the studies is to understand the role of trees, parks, and vegetation in an urban setting. This knowledge will help us to create more sustainable urban areas and more livable cities.

Guiding Principles

In early 2009, U.S. Forest Service and University of Washington scientists conducted informational interviews with about a dozen key organizations and agencies in the region. Many research needs were discussed, leading to a set of guiding principles that address both the process and purpose of the research program:

  • Integrate biophysical and social sciences
  • Explore effects of population growth and landscape change
  • Focus on outcome-based research questions that are “bottom-up"
  • Work across the landscape gradient from urban to wildland areas
  • Study the connections of human and natural systems
  • Promote relationships among science collaborators, in the region and nationally

Research projects fall into six content areas that address Forest Service national and regional strategic research needs:

  • Urban Natural Resources Stewardship and Restoration
  • Ecosystem Services
  • Urban Landscape Assessment
  • Public Health
  • Environmental Justice
  • Water
