Distinctiveness (1=highest,4=lowest): 4 (nationally important)
All top-level predators are present and its rivers support all five species of Pacific salmon.  It also harbors large populations of bald eagles and snow geese.*

Conservation Status (1=most endangered, 5=most intact): 5 (relatively intact)
Although this is the part of Alaska that is most heavily-impacted by humans, it is still about 90% intact habitat.  Threats include logging and mineral extraction, and urban and residential development occurs near Anchorage and Palmer-Wasilla.*
