Could living near mountain lions, also known as cougars or pumas, actually make you safer? The idea sounds surprising because these powerful predators can inspire fear in communities that share their habitat. Yet new research suggests their presence may bring an unexpected benefit: fewer dangerous collisions between vehicles and deer and elk. Scientists found that mountain lions change how their prey uses the landscape, pushing deer into more remote areas and away from places with many roads. The finding offers a new look at how predators can influence human safety without directly interacting with people. The study examined five years of data from Washington State’s Olympic Peninsula. It suggests that living alongside large carnivores can sometimes produce benefits that communities may overlook. The study, led by Justin P Suraci and colleagues, is titled 'Large carnivores shape road safety through effects on prey space use' and was published in Current Biology in August 2026.
