A lot of attention is being paid to the initiative that will be on the Colorado ballot this year. The question is whether the state will reintroduce wolves to Colorado, and various interests are queuing up for a rancorous debate about whether the state should begin this process.

The neighboring state of Wyoming, though, has a decent wolf population, and one argument against the reintroduction measure is that the wolves will do the reintroduction on their own. They will simply walk down from Wyoming and enter Colorado on their own.

Well, yesterday, there was news that wolf tracks were spotted in the snow in the northwestern corner of Colorado. There have also been sightings. An elk carcass has also been found, and wolf howls have been heard. So it is very likely that some wolves are now roaming Colorado, and they may be establishing a pack.

However, this does not change the debate on the ballot question, because if it is passed, these wolves will likely be joined by others.

And, it makes something else more interesting. The ballot question is about gray wolves, but there were historically two subspecies of gray wolf that roamed Colorado.

The ones in Wyoming are Northwestern wolves, but Colorado was also the northern terminus for the Mexican gray wolf’s range. If this ballot question is approved, then a real discussion should be had about restoring Mexican gray wolves to parts of southwestern Colorado.

A huge debate exists about the wolf subspecies of North America, not just with the potentially coyote introgressed “species.”  A real debate exists about whether the Northwestern wolf is the same as the Southern Rocky Mountain wolf, which was also a fairly large wolf.  This also where you get these big debates about giant Canadian wolves with the anti-wolf opposition in much of the West.

What would happen is that you probably would have a gene flow between Northwestern wolves and Mexican gray wolves, and natural selection would favor those that had the adaptations to handle the local prey.

But this probably would cause lots of issues, because Mexican gray wolves are seen as such a unique subspecies that a whole line of them was euthanized for merely showing some dog-like characteristics.

So wolf taxonomy is always an issue with recovery, even if you leave out the domestic dog and coyote introgressions.
