City of Boulder to Implement Additional Seasonal Wildlife Closures on Friday, March 15

City of Boulder to implement additional seasonal wildlife closures on Friday, March 15 

The City of Boulder will implement several seasonal wildlife closures on Friday, March 15, to protect bird nesting habitats and help local populations of osprey, American bittern, burrowing owls and northern harriers to raise their young.

From Friday, March 15, through Tuesday, Oct. 31, the following locations will be closed to protect burrowing owls, which Colorado Parks and Wildlife has listed as a species of greatest conservation concern:

  • Cosslett/Knaus, south of Lookout Road and east of 75th Street.
  • Jafay/Lynch, north of Lookout Road and east of 75th Street.
  • Superior Associates and Kelsall, north of High-Plains Trail.
  • Dry Creek East, northwest corner of the Boulder Reservoir, east of 51st Street.  If no burrowing owl activity is documented, restrictions may change later in the season. Please visit https://bouldercolorado.gov/osmp/osprey-closures for updates. The Boulder Aeromodeling facility will remain open with modified flight restrictions.

The City of Boulder also will close locations near the Boulder Reservoir and Sawhill ponds from Friday, March 15, through Sunday, Sept. 10, to protect nesting osprey, American bittern and northern harrier – a species that is listed as a rare and declining species in Boulder County. These areas will be closed:

  • Axelson, northwest of the reservoir, west of 51st Street. Portions of this property will be closed.
  • Little Dry Creek East, southwest corner of the Boulder Reservoir, east of 51st Street.
  • Little Dry Creek West, west of 51st Street between the Boulder Reservoir entrance and the Eagle Trailhead.
  • Boulder Valley Ranch, west of 51st/55th, west of Eagle Trail and west of the Boulder Valley Ranch pond.
  • Coot Lake wetland, immediately west of Coot Lake. The trail surrounding the wetland is open with voluntary leash recommendations in effect.
  • The southwest corner of the Sawhill ponds property, located west of 75th Street between Valmont and Jay roads.

All designated trails near closures areas will remain open to help visitors view wildlife species as they thrive in their native habitats. Stay-up-to-date on these closures – along with recently instituted closures to protect golden eagles, peregrine falcons and other birds of prey – through an interactive map.

The city’s Open Space and Mountain Parks and Boulder Parks and Recreation departments will lift these wildlife closures if monitoring indicates nesting has not occurred or if no fledglings have been produced. The City of Boulder appreciates the cooperation of the public in protecting these wildlife areas.
