A catalyst for ecosystem recovery

The University of Washington Puget Sound Institute provides analysis, research and communication to inform and connect the science of ecosystem protection.

The big picture: Our comprehensive approach

Ecosystem management in Puget Sound has become increasingly complex. Scientists now recognize that what happens on the land is intricately tied to the health of the water. We face climate change and unprecedented population growth, and researchers have identified thousands of different human-caused pressures on the ecosystem. Given limited resources, how can managers and policymakers make informed decisions about where to focus their recovery efforts?
