Colorado officials plan to capture up to 15 grey wolves from British Columbia's hinterlands to help the Centennial State re-establish the predators' long-lost population.

Colorado Parks and Wildlife began an operation to capture up to 15 wolves in British Columbia and release the predators in Eagle, Garfield or Pitkin counties. The plan marks the second time Colorado will reintroduce wolves through its voter-mandated program to restore the endangered canines.

Colorado Parks and Wildlife staff started capturing a second round of gray wolves on Friday to be released in Colorado in the coming weeks.
