Peregrine Falcons Thrive in Yosemite Through Rock Climber Collaboration

A unique partnership between climbers and conservationists has doubled the number of breeding pairs over 15 years.

The number of peregrine falcon breeding pairs in Yosemite has increased from 8 in 2009 to 17 in 2024.
Climbers helped rescue fragile eggs from cliffs, leading to the successful hatching of 385 chicks since 2009.
Targeted climbing route closures have been implemented to protect nesting sites without significantly impacting park visitors.
The Peregrine Falcon Protection Program balances wildlife conservation with recreational activities in Yosemite.
The use of DDT had previously decimated the peregrine population, leading to their endangered status in the 1970s.
