Abstract
Growing empirical evidence suggest that spawning salmon populations provide measurable nutrient flows back to riparian forest systems, further complicating the dilemma of optimizing harvest management of both timber and fisheries in salmon-rearing watersheds. Such a co-dependent relationship between these two high-value resources begs reconsideration of existing resource management strategies, where frequently timber production is prioritized. Here, I review recent research on salmon benefits to forest growth, all of which focus on the Pacific Northwest region of North America and the endemic timber and salmon species. Additionally, I consider the implications from this ecological co-dependency for existing timber harvest and conservation payment policies. As an example, I apply them to the findings by Zorbrist and Lippke (2007) on Oregon and Washington riparian timber harvesting limits for fish protection, whose economic analysis predict that such restrictions decrease soil expectation value for small landowners.
