In an annual effort to protect several animal species, including nesting raptors and calving elk, Jefferson County Open Space rangers temporarily closed three public spaces — including parts of trails and climbing routes — this month. Two more areas will temporarily close March 1. Visitor services manager Mary Ann Bonnell said the closures affect only 11 of the more than 1,000 climbing routes and only 5.4 miles of the 236 miles of trails the agency oversees, leaving plenty of terrain to enjoy. “A lot of the reasons people come to our parks is to enjoy wildlife,” Bonnell said.
