Food for thought.

The Pacific Northwest region extends from Cook Inlet on the south coast of Alaska through coastal Alaska, British Columbia, Washington and Oregon to northern California. The important waterfowl habitats tend to be similar estuarine, riverine and forested wetland landforms throughout the region. However, the intensity of land use and future threats to waterfowl conservation are extremely different between, for example, the wilderness of Alaska and the urbanized Fraser River delta. Strategic plans for this region have been prepared in three sections: Alaska, British Columbia and the Pacific Northwest of the United States.
Importance to Waterfowl

The Olympic Mountains in Washington and coastal areas of the Outer Sound support the densest U.S. breeding population of harlequin ducks.

The Copper River Delta supports the world's largest populations of nesting trumpeter swans and dusky Canada geese.

More than 10 million waterfowl use the Yakutat, Stikine, Tsiu, Copper and Susitna flats in spring migration.
