American scientists have found that the presence of mountain lions significantly reduces the number of road accidents involving deer, preventing thousands of crashes and saving millions of dollars, according to infohub.kz.
The study by a team of U.S. researchers revealed an unexpected economic and ecological benefit of these large predators. Analysis of data spanning several decades confirmed that the return of mountain lions to their historical habitats substantially decreases deer-related traffic accidents.
Mountain lions alter the behavior of ungulates, making them avoid open spaces and roadways. Additionally, the predators regulate deer populations, preventing overpopulation near infrastructure. According to the authors' calculations, restoring mountain lion populations in the eastern United States could prevent thousands of accidents, save human lives, and save hundreds of millions of dollars in vehicle repairs and medical costs.
The scientists emphasize that large predators serve as natural ecosystem regulators. The findings underscore the need to protect mountain lions and create wildlife crossings for safe animal passage across major highways.
