Alaska occupies a unique role in the conservation of migratory birds in the Pacific region and beyond. As a breeding ground, Alaska is a northern apex for many species of birds that come north for long daylight hours and a burst of plant and animal life that supports successful breeding. Alaska is also a crossroads for arctic birds that breed in Canada and Russia. Migrations to and from Alaska link breeding grounds with winter ranges across the Americas, eastern Asia and Australia, and even Africa.
At one time or another in their annual cycles, 501 naturally occurring bird species are found in Alaska. The diversity and abundance of Alaska’s birds is supported by a large latitudinal range of landscapes from Arctic tundra to subarctic tundra, boreal forest, and temperate rain forest. The sheer size of Alaska- with a landmass of 570,000 square miles and 33,900 miles of shoreline-sustains all, or a large proportion of, some species and populations of birds.
Fortunately, most of Alaska’s bird habitats are unaltered and large expanses of the richest areas are included in within existing conservation units such as refuges, parks, and forests. Thus, the primary conservation challenges in Alaska are to maintain the quality and quantity of bird habitats while minimizing the impacts of growth and development, resource extraction and climate change. Warming of terrestrial and marine habitats is pronounced in Alaska, especially in northern areas, and emerging trends indicate that ecosystem changes will have significant effects on the ranges and diversity of birds.
The Pacific Birds Habitat Joint Venture has included southern and western Alaska since 2001, and has encompassed all of Alaska, including interior boreal habitats and arctic habitats, since 2009.
