Pumas in Washington cut deer-vehicle collisions by 76%, study finds

A new study highlights the role of pumas on Washington's Olympic Peninsula in significantly reducing deer-related road accidents. The large carnivores alter deer behavior, pushing them away from highways and discouraging nighttime movement near roads. This behavioral shift has been linked to a 76% drop in vehicle collisions involving deer in the region. Researchers say the findings demonstrate the broader environmental and safety benefits that large carnivores provide to local communities. The study makes a case for coexistence with apex predators as a practical tool for public safety.
