Originally, the main point of this project was to reduce the chance of flooding. But the effort produced many other ecological, social and economic benefits as well, when Oregon‘s Tillamook Bay got a tidal wetland habitat restoration.
The project treated 443 acres of land (some of it quite watery) to improve salmon habitat and reduce flooding risk.
There were many additional effects, including a rise in real estate values.
A recent report shows how the benefits went beyond the original scope of the work.
Steve Dundas and Graham Shaw at Oregon State University did much of the study work. Listen to them describe it here.
