Study Reveals Mountain Lions Adapt Nocturnal Habits to Coexist with L.A. Recreation

Mountain Lions in Greater L.A.: How They Cope with Human Activity

A recent study shows how mountain lions in the greater Los Angeles area adapt to living near people. The research highlights that these big cats adjust their activity to nighttime to avoid encounters with the over 18 million people who hike, bike, and run in their habitats.

Key Findings

• Mountain lions become more active at night in areas with high human recreation.
• The study covered regions such as the Santa Monica Mountains and Griffith Park over a seven-year period.
• The late mountain lion P-22, who lived in urban Griffith Park, was among the most nocturnal, indicating a strong response to human presence.

Why It Matters
Understanding how mountain lions balance their lives with human activity is crucial for coexistence. This flexibility may help prevent conflicts between wildlife and people.

The Weekend Effect
The researchers examined the “weekend effect,” where outdoor activity peaks during weekends. However, mountain lions do not react as expected to this pattern. They tend to avoid high-recreation areas regardless of the day of the week. Ellie Bolas, a researcher from UC Davis, suggested that mountain lions are already primarily nocturnal, making them less sensitive to these changes.

P-22’s Influence
P-22’s behavior helped shape the study’s conclusions. Living close to human development, he adapted by becoming very nocturnal, indicating that mountain lions are capable of adjusting their habits to stay safe around people.

This research provides hope for wildlife conservation, showcasing that mountain lions can thrive in urban environments by modifying their behaviors.
