Adirondack Rock Climbing Route Closures

Pergrine Falcon

Peregrine falcons, an endangered species in New York State, nest on cliffs in the Adirondack Mountains. The population of peregrine falcons has steadily grown since the DEC undertook hacking programs in the Adirondacks in the late 1970s.

Cliffs with known peregrine falcon nesting sites are monitored annually throughout the Adirondacks. Rock climbing routes with active nest sites are temporarily closed to prevent any disturbances that might interfere with the successful raising of the young peregrine falcons.

The closure of climbing routes is based on a number of factors, primarily the route's proximity and visibility to a nesting site. Each situation is unique and a specific distance from the nest site can not be used to make a closure determination. DEC's priority is protecting an endangered species; however, attempts are made to maximize the opportunities for climbing at the same time.

At the beginning of the season DEC closes whole or large portions of cliffs where peregrine falcons have regularly nested. This allows them to choose a nesting site without any being troubled by climbing activity. They often choose a site quickly and begin nesting earlier, than when the cliff's were subject to climbing activities. Climbers benefit because an earlier nesting start results in an earlier fledging of the young and therefore the closed routes are re-opened sooner.

July 31, 2015

All rock climbing routes in the Adirondacks are now open. DEC appreciates the patience and understanding of the rock climbing community. DEC is completing the tally of the number of falcons fledged from Adirondack nest sites. Those figures will be provided here at a later date.
