This topic always amuses me.
Wolves don't know which state they're in. There is plenty of habitat in Colorado to support wolves, not to mention the largest elk herd in the world. Wolves travel a great deal. Reintroducing wolves in CO will only speed up the process that started when they reintroduced wolves in Yellowstone, and for that matter, there were wolves in Yellowstone before the reintroduction in small numbers. People need to consider how much these animals travel and how they form new packs. As packs grow, juveniles leave and start new packs. Yes, they affect elk behavior. An animal with no natural predator will behave very differently. They displace elk, as
@mtmuley said. And they eat elk. A lot of elk. 20+ per year per wolf is a good average.
But this idea that we have to "take matters into our own hands" is impossible. Whether or not they voted to reintroduce wolves, they would expand into CO and beyond eventually. They will go where the food and habitat exist to support them. Shooting them out of existence doesn't work, even where it is legal. Love or hate them, they're here to stay now. Not just in MT, WY, ID, OR etc... They'll fill in the gaps without any help
