Seasonal Closure Protects Peregrine Falcons

Dunlap, CA., April 8, 2008.  The area within 1/4 mile of Chimney Rock in the Hume Lake Ranger District, Giant Sequoia National Monument, Sequoia National Forest is now closed to all entry.  The area is a traditional nesting site for Peregrine falcons, a species endangered in California.  The closure will remain in effect until August 15 or when nesting concludes and the birds leave the area.

Historically, peregrine falcons nested on the cliffs in the Chimney Rock area until the 1970s, when DDT caused nest failures that led to their disappearance.  In 1993, peregrine falcons were found using the cliff north of Chimney Rock.  Disturbance by humans threatened the nesting success of the birds. 

To avoid abandonment of the nesting site, a seasonal closure was implemented.   Monitoring by volunteers and biologists has found regular use of the area and a need for seasonal closures since that time.  In 2006, Peregrine falcons nesting on Chimney Rock successfully fledged a chick for the first time in recent history.
