There are approximately 13,135 to 16,635 grey wolves and approximately 90 to 110 red wolves living in the United States. The biggest population of grey wolves is in Alaska, where approximately 7,700 to 11,200 wolves reside, according to the Wolf Conservation Center.
Wolves live across the continental United States, except in the Northeast, where the population is officially zero. Grey wolf populations are declining because of the destruction to their habitat and persecution by humans. Hunting grey wolves is legal in several states.
The Alligator River National Wildlife Refuge in northeastern North Carolina is the only place where red wolves live in the United States. They are under Federal protection because they are one of the world’s most endangered animals of the canid family. Approximately 178 red wolves live in captivity.
