The Puget Sound Pressures Assessment, or PSPA, offers a tool to better understand the pressures on the Sound’s freshwater, marine-nearshore, and terrestrial resources. It also helps us to identify the critical ecosystem vulnerabilities that should be addressed if we are to achieve sustainable, long-term protection and recovery.

To support shared learning and collaboration among partners and across projects, the Partnership has developed two taxonomies describing the sources of pressure and related stressors on the Puget Sound ecosystem.

In 2014 the Puget Sound Partnership finished the first PSPA evaluation using a methodology developed by advisors from the Partnership Science Panel. The 2014 PSPA involved a systematic, expert-based evaluation of the potential effects of stressors identified in the PSPA on identified ecosystem endpoints, such as habitats, species, or ecological processes.
