See 2006 closures below.

Since the 1960's, populations of raptors, or birds of prey, have declined dramatically nationwide. Loss of habitat, increases in pesticide use, and hunting have taken a great toll on their numbers. Recent restoration efforts, combined with stricter laws and key habitat protection, have stimulated a recovery of raptor populations across the country.

Rocky Mountain National Park contains excellent habitat for girds of prey. Golden eagles, kestrels, turkey vultures, peregrine and prairie falcons, and re-tailed and Cooper's hawks are especially suited to the park's craggy rock outcroppings.

Unfortunately, the same cliffs that lure raptors also attract rock climbers. The presence of climbers is likely to affect the nesting success of raptors.

n order for wildlife managers to gather information and ensure that raptors can nest undisturbed, specific areas within the park are closed temporarily to public use during nesting season. With you support and cooperation, birds of prey - superb indicators of an ecosystem's health - can thrive in Rocky Mountain National Park.

Initial closures occur in March and April, when raptors return to the region and scout for nesting sites. Areas containing general habitat preferred by raptors are closed during this time. Once raptors have selected nesting spots, the initial closures are lifted or adjusted. The specific areas which raptors choose for nesting sites are closed.

• Checkerboard Rock
• Lightning Rock
• Batman Rock
• Batman Pinnacle
• Thunder Buttress
• The Parish
• Alligator Rock
• Sheep Mountain
• Deer Ridge Buttress and Twin Owls
• Rock One

These closures include the named formations as well as areas extending 100 yards in all directions from these formations. The perimeter around Alligator Rock extends for 200 yards in all directions. Closures include all climbing routes, outcroppings, cliffs, faces, ascent and descent routes and climber access trails to the named rock formations.

WHEN: Effect on March 11 and will continue through April 30. These closures may be extended longer or rescinded at an earlier date if determined necessary.

The National Park Service is committed to preserving birds of prey. The same cliffs that attract raptors also appeal to climbers. The cooperation of climbing organizations and individuals is essential to the successful nesting of raptors in the park.
