The Boulder Open Space and Mountain Parks department and the U.S. Forest Service will begin enforcing seasonal closures at numerous areas Friday to protect long-established nesting sites for predatory birds.
The areas being closed by the Forest Service are Security Risk, Eagle Rock, Blob Rock and Bitty Buttress in Boulder Canyon, according to a news release.
Boulder Open Space and Mountain Parks is closing the following areas, according to a news release:
Lefthand Canyon Palisades (The Buckingham picnic area will remain open.)
Mount Sanitas, First Buttress (The Mount Sanitas trail will remain open.)
Gregory Canyon Amphitheater
Designated parts of the Third Flatiron

The closed areas provide vital nesting territory for golden eagles and falcons, according to officials.
Signs will be posted at key access points for all of the closed areas in Boulder Canyon. Volunteers and Forest Service staff members will monitor the areas.
The city can issue trespassing violations that could result in 90 days in jail or fines up to $1,000 for those who do not respect the closures within Boulder's jurisdiction.
