In 2003 staff at the Skagit River Systems Cooperative found higher then typical rearing of chinook salmon in small quiescent Embayments in the Whidbey Basin. This led to the pocket estuary hypothesis, which has driven restoration planning in the nearshore and development of an extensive body of work (see:Nearshore habitat planning for salmon recovery). Successive work in observing juvenile salmon use of estuaries (see: Evaluating Salmon Rearing Limitations in River Deltas) has suggested that during large out-migrations, limited space in deltas results in fish seeking habitats in the nearshore. Regulatory work to quantify nearshore habitat services as part of the Puget Sound Nearshore Habitat Conservation Calculator encouraged the reconsideration of the evidence that describes patterns of non-natal rearing of salmon along River Deltas, Beaches, Embayments, and Headlands. This led to PSEMP support for an evidence synthesis project as part of the Science Sprints to Support Regulation effort, which incorporated use of this wiki.
