NotesMillions of dollars have been spent in enhancing habitats to aid recovering populations of salmon on the Oregon Coast. How well have enhancement projects done? Does there seem to be a relationship between restoration projects and salmon recovery? The author addresses these questions. ”My analysis showed that from 1994 to 2012 only 3 of the 21 independent populations from the ESU, the Alsea, Salmon, and Tillamook had statistically significant recovery. To evaluate the relationship between habitat restoration and coho recovery, I ran a correlation between the rate of recovery and the amount spent on restoration for each ESU population. The rate of recovery increased as total dollars spent on restoration increased, but it was a very weak relationship…” (from the Abstract) The author concludes by suggesting ways to improve restoration efforts.
