I think the rise in coyote pops has more to do with price and less people out trying to kill them.It actually is at least partially about management skills. We simply forgot how to manage predators for a while and are now being forced to deal with new predators in places they have not been before and numbers like we have never seen. This isn't just about bears, but also lions, wolves, coyotes, etc.. There used to be few wolves in the US, now they have populations from the great lakes to Mexico with sightings in places like Iowa, Kansas, South Dakota, etc... That all happened in the last 20 years. Even Coyote populations are booming recently as more are living in urban areas where they are not harassed like they can be in rural areas.
Predators have risen in numbers substantially the last 2 decades and it's time our game managers catch up. I understand they are somewhat hindered on griz but the other species like black bear, lions, wolves, and coyotes are within their control for the most part so they have nobody but themselves to blame.
the season here on yotes is open 365 so I don't know what else they could do short of bounties.
wolves are still out of their control ,simply because , while many buy a tag, very few actually target them.
same actually goes for blackbear and lion.
most hunters carry a just in case tag but do not really hunt them.
