Progress to dateProgress to date
7 million native oysters spread at 80 sites since 1999
1 acre of tidelands in Liberty Bay enhanced with shell in 2005 and 2006
Pilot enhancement in Henderson Inlet
5 acres of enhancements planned in 2007

1. Habitat Enhancement 1. Habitat Enhancement Emerging as Key StrategyEmerging as Key Strategy
Enhance substrate with shell near existing populations where substrate is too soft to support settlement
This enables remnant population to recolonize historic areas AND
Maintains genetic integrity of local population

2. Seeding in Select 2. Seeding in Select LocationsLocations
In the absence of genetic information, seeding is only pursued in areas where there is clearly no larval production and no local population to trigger a comeback – and then only if there is a population relatively nearby.

Oyster restoration in the lower intertidal is the missing link in salmon recovery efforts
Quantitative monitoring data on ecological benefits of oyster restoration is essential to securing money

Geographic area within which restoration can occur is tightening in the absence of genetic information
Until remnant populations are located, restoration is at a standstill in San Juan Islands and the North Sound.

Restoration ImperativeRestoration Imperative
We need a system that is productive, full of life and capable of sustaining us.
- Looks vs. Substance
Oysters are an essential part of that system.

Why oysters and Why oysters and restoration matterrestoration matter
Improve the ecosystem (filtration, habitat, food)
Give people an incentive to protect clean water and habitat
Make the resource REAL – people need to experience the productivity of Puget Sound to value it.
