Also, is there a reason problem GYE or Northern Rocky bears aren't moved around to promote pop growth, or non-problem bears for that matter? I mean if the goal is to use GYE as a "bear well" why not catch a couple of dry sows every year and drop them off in the Belts, Bridgers, Cabinets, Anaconda, Etc.
Yes, there is a reason. Reason being that when the Gbear was listed, the states, in this case Montana, worked with the USFWS to determine what was the required range and populations to be considered "recovered." That was a negotiation, to some degree with MT at the metaphoric gun point, with the negotiation being that MT (and other states) would make huge changes to management activities within the agreed upon geographic areas deemed necessary for a viable and recovered population.
Now, some who do not like how that was negotiated, want to change it and will litigate to get the outcome they want. And their request to move bears to newly identified places that will be "socially unacceptable" (USFWS term) and areas with high conflicts of other human activities is not only reneging on the deal that was struck, but will cause an uproar of a high degree.
The USFWS is comfortable with their science and the fact they and their partner-states have fulfilled the requirements for a viable and recovered Gbear population. They are not going to risk credibility by moving problem bears to places where it was negotiated to be excluded from the Primary Conservation Area.
