Cougars Lower the Risks of Car Crashes by Hunting Deer
The presence of cougars around roads cutting through forests or around a development edging up to the woods, the researchers found, made deer avoid these areas, leading to fewer accidents.Cougars—also called mountain lions, panthers, or pumas—are native to the Americas. But due to habitat loss and hunting their range in North America dropped off considerably following European colonization. Now, cougars are mostly found in the western US states and a small part of Florida.Deer, on the other hand, have flourished.
