City of Boulder Lifts Seasonal Closures That Protect Sensitive Wildlife Habitats

This Wildlife Protection Effort Helped Local Birds of Prey to Produce Many Fledglings in 2017

Prairie Falcon

The City of Boulder’s Open Space and Mountain Parks (OSMP) Department today lifted seasonal closures protecting habitat that comprises some of the best areas in Colorado for nesting birds of prey.

This wildlife protection effort helped local birds of prey to produce many fledglings in 2017, including: six peregrine falcons, five prairie falcons and four golden eagles. This year, 42 volunteers logged more than 1,200 hours monitoring raptor nesting sites, providing important information that helps OSMP to better manage its wildlife habitat management efforts.

Learn more about how the City of Boulder protects raptor habitats and the city’s dedicated raptor monitor volunteers – some of whom served for more than 20 years – in a video series produced by OSMP Department and Boulder 8 TV.

OSMP today lifted these seasonal raptor closures surrounding Boulder:

  • Third Flatiron, including Queen Anne’s Head, W.C. Fields Pinnacle, 1911 Gully and the Ghetto, the East Bench & West Bench, the East & West Ironing Boards, The Fin, Green Thumb and Jaws.
  • The Matron
  • Shadow Canyon on both sides of the Shadow Canyon Trail.
  • The Mickey Mouse Wall
  • Skunk Canyon
  • Nebel Horn ridge and the area north of the Fern Canyon Trail
  • The Coal Creek area east of Highway 93 and near Marshall Lake. A parcel north of Coalton Trail remains closed to protect nesting burrowing owls.

OSMP also lifted several closures that protect grassland songbirds, whose populations are declining throughout the United States. Closures lifted today are:

  • Both sides of the Greenbelt Plateau Trail from the Community Ditch Trail to the Greenbelt Plateau Trailhead on Highway 128. Starting Aug. 1, guardians registered in the Voice and Sight Tag Program may walk their dogs off leash on the Greenbelt Plateau Trail.
  • The area north of Community Ditch Trail and west of Highway 93.
  • The area north of Flatirons Vista North Trail and west of Highway 93.
  • The area north of the South Boulder Creek West Trail, east of the Bluestem Connector and south of Shanahan Ridge.

 The department’s efforts to protect raptor and grassland bird nest sites rely heavily on the public’s cooperation, and OSMP thanks visitors for respecting closure areas.
