Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin

The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...

Scientific Support of Salmon and Steelhead Reintroductions in Impounded River Basins of the Pacific Northwest

Salmon and steelhead populations in the Pacific Northwest were severely affected by hydropower development that occurred during the first half of the 20th century.  Impassable dams were constructed on many rivers throughout the region which prevented returning adult salmonids from accessing important habitats where spawning and rearing historically occurred.  In the past two decades...
