WRIA2 Recovery Plan Hypotheses
San Juans provide important nearshore and marine habitat for salmon San Juans provide forage for salmon Part of the challenge is understanding how salmon use different habitats at different times in their life cycle.

Measure of degradation or intactness at the shoreform scale. Processes Evaluated: • coastal sediment dynamics, • wind and waves, • tidal hydrology, • freshwater hydrology, • tidal channel formation and maintenance, • detritus potential, • solar radiation :Outcomes For each individual shoreform: sum of process degradation; normalized (sum divided by the # of processes); % of degradation; # of stressors; type of stressor.
Nearshore Process Degradation
Most impacted areas on ferry- serviced islands near urban growth areas, villages, marinas, bays, etc. Identify Priority Areas for Protection and Restoration Actions

Priority Salmon Recovery Regions Maps and Findings 1. Waldron / President Channel 2. Rosario SW 3. Juan de Fuca / S. Lopez 4. Haro Strait NE

Source: Friends of the San Juans 1. Waldron / President Channel Landscape Region
The top salmon recovery action for this region is protection. With virtually all shorelines ranked as top or medium protection priorities, restoration of the minimally degraded sites in this region is also a top salmon recovery priority for San Juan County. The Waldron Island and NW Orcas sections of this region are dominated by drift cell systems, while the Sucia Island and West Orcas Island regions consist primary of rocky shores and pocket beaches. Highest correlation with existing protection priorities. Significant public ownership. Highest sea level rise resiliency. 2. Rosario SW
Source: Friends of the San Juans 2. Rosario Channel SW Landscape Region
High percentage of protection priority shoreforms. Rocky shores, pocket beaches and drift cell systems. Nearly all shoreline ranked as high or medium protection priority (north) and areas of low degradation that are top restoration (and medium protection) priorities (south). Highly degraded shoreforms are extremely limited. Scattered public ownership. Significant overlap with existing restoration priorities for restoration projects along the east shorelines of Decatur. Second highest long -term priorities based on SLR resiliency, as well as one site (Decatur Island) where enhancement action can improve resiliency to sea level rise. 3. Juan de Fuca / S. Lopez
Source: Friends of the San Juans 3. Strait of Juan de Fuca / S. Lopez Landscape Region
Balanced combination of protection and restoration needs. Exclusively rocky shores and extensive pocket beaches. High percentage of high protection priority shoreforms. Multiple feasible priority restoration opportunities at pocket beaches with low degradations scores. While the majority of the region has degradation scores of zero or low, considerable areas of highly degraded shores also exist along Agate Beach, Barlow Bay and MacKaye Harbor. Some long term resiliency to sea level rise, primary smaller, dispersed intact or low degradation pocket beaches. There is some public ownership in the region. Some overlap with existing priorities, especially protection. 4. Haro Strait NE
Source: Friends of the San Juans
4. Haro Strait NE Landscape Region
Primary salmon recovery need in this region is restoration. Few fully intact areas (rocky western shore along Haro Strait). Highly diverse, with all shoreforms represented. Rocky shores the areas with minimal process degradation. Pocket beaches and drift cells are moderate to highly degraded. Substantial integrated restoration priorities, the largest amount of any region in the county, mostly concentrated at the northern half of the region (westcott, garrison, mitchell bays). Limited public ownership in this region, primarily located at English Camp National park. Many small sites resilient to sea level rise; a few protection and most restoration priorities, mostly on pocket beaches.
