Results of effectiveness studies are being communicated to decisionmakers as they plan the next round of recovery actions. The lessons emerging from these effectiveness studies will make future investments more effective, both in terms of cost and outcomes.
Example: Lessons learned about effective habitat restoration
For all estuary restoration projects, investigators documented the immediate use of newly created habitat by salmon and other species. For example, Skagit River restoration efforts added habitat to support an estimated 106,000 young Chinook salmon every year.
Lessons learned about effective habitat restoration are:
- To support habitat formation, ensure a source of sediment and the channel structure to retain it.
- Test new drainage infrastructure before removing old dikes.
- Control invasive plants so native plants can take hold.
Current effectiveness monitoring fact sheets and narrative summaries include:
- Keeping shellfish beds open by reducing fecal coliform bacteria (Samish Basin)
- Reducing stormwater pollution: Selecting the best wet-weather management actions (Seattle)
- Habitat restoration: King County re-establishing native forests on restoration sites
- Habitat restoration: Restoring tidal wetlands to support Chinook salmon (South Fork Skagit River Delta)
- Habitat restoration: Restoring tidal wetlands to support young salmon and reduce flood damage (Fisher Slough, Skagit River)
- Habitat restoration: Restoring tidal wetlands to support salmon (Snohomish River Delta)
- Habitat restoration: Creating natural habitat for salmon and other wildlife (Nisqually Delta)
