At least in Colorado it just means they want animals to hunt. But they also want to privitise all the land, use it for ranching, defund state efforts to protect natural areas, and expand fracking. They don't hike and they don't believe climate change exists despite it rapidly endangering those alpine animals.
It's the same kind of demonic fuck-fuck game they play with terms like "save the children" or "family values".
edit: Actually, I'm part of a ranger org with some 300~ members. Most of them are boomers and I've spoken with dozens of them. Not a single one has been a right-winger. They try to co-opt conservationism for their ranching and hunting, but even the most basic work of stewardship is so far beyond their capacity.
