Sadly, states that study cougars generally do it to verify supply and demand levels for hunters

NGPC suspended the opportunity for sport hunting of mountain lions in 2015. We applaud them for doing that, but sadly studying lions in Nebraska is just a prequel to providing recreational opportunity for those that enjoy killing cougars. There has never been scientific evidence that promotes sport hunting of mountain lions- that says we must do this. The evidence that is collected simply allows the agency to maintain a population that can provide a sustainable number to be killed.

Most mountain lion research conducted by states is to enable hunting.
