> An estimated 528 wolves resided in the Greater Yellowstone Ecosystem as of 2015. As of December 2021, there are at least 95 wolves in the park. Eight packs were noted. This count marks a decrease of 23% from 2020 but is close to the previous decade's average end of year count (2010-2019 average = 94.5).

> Within Yellowstone National Park, no hunting of wolves is allowed. Outside the park, Montana, Idaho, and Wyoming regulate and manage hunting. Because wolves do not recognize political boundaries and often move between different jurisdictions, some wolves that live within the park for most of the year, but at times move outside the park, are taken in the hunts

So there's a clear evolutionary advantage for wolves that do recognize political boundaries. I wonder if that has long-term effects on wolf-pack territories.

Wasn’t there an article about exactly this topic a few years ago or am I crazy? Feels weird to do a tweet thread about it without even a reference to it.

Main purpose of these type of tweets are to go viral and get more followers. Hence no citing articles or anything useful like that..

> From 1995 to 1997, 41 wild wolves from Canada and northwest Montana were released in Yellowstone

That's more than 14 (digits swapped?), but still not a lot from a genetic health standpoint. Seems like there's some exchange with other populations in the Northern Rocky Mountains, who in turn mate with wolves from Canada, so it might be just fine. But it's a bit weird for the article to even mention the issue, only to then get lost in a tangent about one prevalent mutation.
