The Hidden Guardians of Washington's Roads A recent study published in 'Current Biology' has revealed an unexpected trend in Washington state: pumas are linked to a significant decrease in vehicle collisions involving deer.
According to the research, areas with puma populations have seen a 76% reduction in deer vehicle accidents. The study attributes this phenomenon to the altered behavior of local deer populations.
When pumas are present, deer tend to shift their activity patterns and avoid roads, resulting in fewer accidents.
