Did you know Yellowstone researchers study people in the park? Park staff like Jenni use a variety of tools, including trail counters, to learn more about visitation in popular areas of the park. While these trail counters might look like small cameras, they actually collect data by detecting body heat as people pass by them on a trail. This data helps us understand when sites are most crowded, how trail use changes throughout the year, and ultimately informs park management when making decisions regarding visitor use at a site.
