MONTICELLO — Beginning Thursday the Bureau of Land Management’s Monticello field office will temporarily close three climbing walls during peregrine falcon nesting season.
The three walls include Reservoir Wall, Cat Wall and The Wall. Notices of the temporary closures will also be posted on the ground with signs at trailhead areas. All other walls, cliffs and climbing routes will remain open.
Peregrine falcons use shallow depressions on ledges, cliffs and even high-rise buildings to create nests. Pairs mate for life, and once they establish a nesting site, they may return to the same nest year after year. Minimizing human disturbance at critical times of the year aids in successful fledging.
Climbing routes will be reopened as soon as practical. Wildlife biologists will monitor the three climbing walls throughout the 2018 nesting season to determine which nest sites are active, which are not and when fledging occurs.Comment on this story
Typically, by late April or May, biologists can determine whether there are active nests in an area.
Walls without active nests will be opened at that time. Walls with active nests will remain closed until the young birds have fledged, usually in late July.
The peregrine falcon was removed from the Federal Endangered Species list in 1999. According to the BLM, peregrine populations in Utah continue to recover statewide, thanks in part to cooperation from the public and climbing communities in helping land managers protect nesting habitat during critical times of year.
