<P> The U.S. Fish and Wildlife Service claims the Cabinet - Yaak and Selkirk areas are linked through British Columbia, a claim that is disputed . U.S. and Canadian national parks, such as Banff National Park, Yellowstone and Grand Teton, and Theodore Roosevelt National Park are subject to laws and regulations designed to protect the bears . </P> <P> On 9 January 2006, the US Fish and Wildlife Service proposed to remove Yellowstone grizzlies from the list of threatened and protected species . In March 2007, the U.S. Fish and Wildlife Service "de-listed" the population, effectively removing Endangered Species Act protections for grizzlies in the Yellowstone National Park area . Several environmental organizations, including the NRDC, brought a lawsuit against the federal government to relist the grizzly bear . On 22 September 2009, U.S. District Judge Donald W. Molloy reinstated protection due to the decline of whitebark pine tree, whose nuts are an important source of food for the bears . In 1996 the International Union for Conservation of Nature moved the grizzly bear to the lower risk "Least Concern" status on the IUCN Red List . </P> <P> Farther north, in Alberta, Canada, intense DNA hair - snagging studies in 2000 showed the grizzly population to be increasing faster than what it was formerly believed to be, and Alberta Sustainable Resource Development calculated a population of 841 bears . In 2002, the Endangered Species Conservation Committee recommended that the Alberta grizzly bear population be designated as threatened due to recent estimates of grizzly bear mortality rates that indicated the population was in decline . A recovery plan released by the provincial government in March 2008 indicated the grizzly population is lower than previously believed . In 2010, the provincial government formally listed its population of about 700 grizzlies as "Threatened". </P> <P> Environment Canada consider the grizzly bear to a "special concern" species, as it is particularly sensitive to human activities and natural threats . In Alberta and British Columbia, the species is considered to be at risk . In 2008, it was estimated there were 16,014 grizzly bears in the British Columbia population, which was lower than previously estimated due to refinements in the population model . </P>
