Residents have said the wolves are hungry, increasingly desperate and a potential threat to children. "The wolves don't have enough caribou to eat, so they have to search for something else. Where the wolves are camping out now are houses that have little 7- and 10-year-old children," said Cindy Beamer, general manager of the Isanotski Corp., which represents Alaska Natives on the 1,571-square-mile island. State officials have said they are obligated by law to maintain a healthy enough caribou herd to provide subsistence hunting of the animal for Unimak residents, who also depend on fishing. While there were 1,200 caribou on the island in 2002, there were fewer than 300 during the official count in 2009. State officials in court Monday presented the results of a survey conducted Sunday that showed only an estimated 250 caribou surviving.
