One of the Phoenix Zoo’s ongoing projects is wildlife conservation, where they work to maintain healthy local populations of everything from ferrets to springsnails.
One species of special interest for some zoologists is the Mount Graham red squirrel. There are less than 300 of these squirrels left in the world, most of which live in the Pinaleño Mountains.
Stuart Wells, director of conservation and science at the Phoenix Zoo, said work on growing the Mount Graham red squirrel population is a slow process. The squirrels have relatively small windows for breeding, but the zoo is confident they can eventually get the squirrels off the endangered species list.
