The National Park Service says the population of wolves occupying Denali National Park in Alaska is the lowest it has been in almost 30 years, with an aerial population survey conducted in March counting only 50 individuals. This is five fewer wolves than last year and the lowest number since biologists started tracking the Denali wolf population in 1986.
The population has been in decline for almost 10 years. In 2006, biologists estimated 116 wolves in the park.
