(Denver, CO) -- Oregon could be sending some wolves to Colorado. Colorado Parks and Wildlife is running into an unexpected problem with their plan to reintroduce wolves in some parts of the state. The agency is asking other states for the wolves that will be used in the effort. Idaho and Wyoming have declined Colorado's request for help, leaving Washington state, Oregon and Montana as possible sources. A C-P-W spokesperson says discussions are ongoing but adds that no agreements have been reached. The wolf reintroduction is supposed to begin by the end of this year.
