The Puget Sound Institute has invited representatives from six major ecosystem recovery projects for a two-day workshop, May 14th and 15th in Seattle. Participants will represent Chesepeake Bay, Everglades, Long Island Sound, San Joaquin/Sacramento Delta, Columbia River Estuary, and the Louisiana Coast. The workshop is being organized by PSI Research Scientist Nick Georgiadis, and will look at ways that science can contribute most effectively to large-scale recovery efforts, including Puget Sound. Topics include challenges relating to scope, complexity and cost in large and complex systems.
