Boulder announces closures to protect nesting birds

Boulder is implementing several seasonal wildlife closures in order to protect bird nesting habitats and to provide adequate sanctuary for osprey, American bittern, burrowing owls and northern harriers to raise their young. Interior sections of some local parks will close, while trail access will remain open.

The following locations will be closed beginning Friday through Oct. 31 to protect nesting burrowing owls:

• 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.

Additionally, the following locations near the Boulder Reservoir and Sawhill ponds will close from Friday through Sept. 10, to protect nesting osprey, American bittern and northern harrier:

• 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.

Boulder‘s Open Space and Mountain Parks and Boulder Parks and Recreation departments may potentially lift these location bans if monitoring indicates that bird populations are not active in these areas. For more information and updates on bird area restrictions visit:
