ALL 2017 SEASONAL RAPTOR CLOSURES ARE NOW LIFTED

Every year a variety of local crags are closed to protect nesting raptors. As climbers we should see it as a privilege that we can share these few crags with our winged friends, and an honor to let them have solitude to reproduce. It is only for half of the year, on a small fraction of the available nearby climbing terrain. Please help spread the word: do not climb on these formations during the closure period! As the season progresses and it is known which nesting sites are active, some of these formations are re-opened to climbing before the deadline. We work to keep this page current as those changes are made.

———————————————————————————————————

Each year from February 1 to July 31 some climbing crags are closed to protect nesting raptors. The closures help protect long-established raptor nesting territory, including vital alternate nest sites. Undisturbed access to multiple nest sites is important for birds of prey, especially early in the nesting season, to give them a chance to visit multiple nests during courtship and to select a site for the season, free of human influence.

“As part of a small team of volunteer climber-biologists, we install trail cameras on the cliffs before the nesting season and make observations to determine when and where the eagles choose to nest. Once nesting is confirmed by observations of incubation behavior and/or an egg, the USFS opens the other areas. Ongoing observations are used to keep track of the number of eagles fledged and sources of mortality. Once fledging is confirmed, the nest cliff is opened again to climbing. This is a collaborative effort built on trust and shared interest between the climbing community, biologists, and USFS, so please get the word out. (Knuckleheads who violate the closures to climb anyway, selfishly violate that trust, put the eagles at risk of nest failure, and face a hefty fine.)

Climbers played essential roles in the research and recovery of peregrine falcons and Sierra bighorn sheep, and brought the California condor back from the brink of extinction. It is our time to do our part again, and respect the closures when they are in effect, as golden eagles face an uncertain future because of threats from wind turbines, lead contamination, electrocutions, and habitat loss.”
