Throughout the historic distribution of wild salmon in the North Pacific, only Alaska and Russia’s Kamchatka Peninsula claim vast undeveloped watersheds that support healthy wild salmon populations. Alaska’s annual runs of wild salmon average more than 180 million. These fish sustain healthy wildlife, families and rural economies.
Yet Alaska is not immune to the development pressures that have strained salmon populations elsewhere in the North Pacific. With help from a range of private and public partners, the Conservancy is restoring salmon streams in the Tongass National Forest and in the Matanuska-Susitna Basin.
Every year, the streams of the Matanuska-Susitna Basin fill with hundreds of thousands of wild salmon. Ocean-bright chinook, coho, sockeye, pink and chum pour into the rivers, feeding everything from world-class rainbow trout, char and grayling to bald eagles, brown bears and people.
Though the headwaters of the basin include some of the wildest lands in the entire country, the lower watersheds of the basin comprise one of the fastest growing areas in Alaska. This growth can harm salmon-bearing waters.
The Conservancy and its partners are restoring once-lost habitat for wild salmon in Colter Creek, a tributary to the Little Susitna River. Colter Creek offers habitat for young coho and chinook salmon.
In 2008, the Conservancy:
Lush and verdant Prince of Wales Island is the nation’s third-largest island and its forests are a giant nursery for wild salmon. Its coastal rainforest, salmon streams and estuaries provide for a rich a subsistence tradition among Native Tlingit and Haida people. More than 100 inches of yearly precipitation recharge the waters where five species of salmon spawn.
Salmon provide the foundation for the entire system, but fifty years of large-scale logging and roadbuilding has left its mark on Prince of Wales Island. A transition toward sustainability is now underway: Salmon habitat restoration projects are allowing wild salmon to return to spawn and grow in streams where the quality of habitat had declined.
In the Harris River watershed, the Conservancy has worked with the U.S. Forest Service to restore significant portions of these salmon-bearing waters. In this highly productive four-square mile watershed, crews have rebuilt a river and its tributaries. This has included:
A series of landslides and other effects of erosion prompted the 2006-2007 restoration of Sal Creek, a coastal watershed on Prince of Wales Island. In this watershed, restoration crews:
A highway causeway built in 1964 blocked natural tidal flow through the north channel at Klawock Lagoon. This has impeded fish passage through the lagoon and caused a decline in beds of native eelgrass--a key nursery habitat for young fish.
