Coloradans who are not happy with the wolf reintroduction plan are trying a new tactic, one that has the potential to change the course of the wildlife landscape: another popular vote.

The Middle Park Stockgrowers Association says they feel like they are "back at square one" when it comes to their opposition to the reintroduction of more wolves in Colorado.

It just became glaringly clear to me and to thousands of other people that this law was just not working for many stakeholders in the state."

Colorado advocates file ballot measure to repeal wolf reintroduction program, citing economic harm and threats to food security.

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.
