6/18/25: USFS has been monitoring Lime Canyon for nesting peregrine falcons, and a pair has established a nest. The active nest site is found in the “Endless Wall & Magic Forest areas. They request not climbing there.

2023: the nesting peregrine falcon pair at Lime CC are in full swing & a temporary area closure surrounding the nest was now in effect until 8/1/23 or rescinded earlier. Information is posted at the site. Climbing is not affected at other areas in Lime CC as a result of this temporary area closure, including at Endless Wall in the Jellystone & the north end of the canyon. Specific to the Endless Wall, the closure begins about 75' R of Fruit of the Linen extends about 2000' up the main canyon to a point about 180' north of the overhead powerline.

In 2022: the closure ended. During monitoring, a tech saw no falcons/young on the cliffs or nesting area seen earlier that season. An adult flew around the main canyon & was calling. The young were able to fly, & the family was in the area but not nest dependent.

In 2022: from P. Nyland - the peregrine falcons returned in 2022 to nest in Jellystone, Lime CC. Thus, White River NF closed the area depicted in the attached Forest Order, effective 6/9-8/1/22.

2 peregrine falcons nested here in 2020 during a similar closure. In 2021, falcons did not nest in this area & a closure ended.

2 were attending a nest. During my last monitoring, both birds were highly agitated until I backed away from the cliff edge. The nest was in a location visible from access & climbing routes at the Endless Wall & Magic Forest. In 2020, climbing was possible at the Endless Wall during the nest & nest-departure phases, but that year the nest location made the pair & their young reactive & vulnerable to humans.

The closed area includes the cliff faces, cliff tops, climbing routes, & access routes to Magic Forest & Endless Wall. The cliff tops were in the closure, b/c we saw peregrines perched there. Closure info is posted at the start of the access from FR 400. Closure ended Aug. 1.



Older: as of 6/20/21, after speaking with P. Nyland, NF Biologist, the study to date showed no evidence of nesting. As a result, the NF anticipated no raptor nesting closures. If evidence of raptor nesting is found, the situation could change, but for now Lime CC & the nearby areas are open.

The White River NF proposes to establish a 5 year reg., a “Special Order,” restricting human occupancy surrounding a peregrine falcon nest site during the nesting period in Lime CC, Eagle County, Aspen-Sopris Ranger District, potentially from May 15 to July 31 each year based on nesting.

The proposed Special Order extends a short-term restriction from 6/1-8/1/20 after monitoring showed an active nest for the fourth year from 2016-20, & within the past two years in close proximity to popular climbing routes. The cliffs of Lime CC are unique & have the specific resources needed for local peregrine falcons to nest, lay eggs, & rear young. During this life stage, adults & young peregrine falcons can be disturbed by humans.

It is our intent to protect the area surrounding the nest site using science-based peregrine falcon information & monitoring. As possible, the restriction may allow for climbing & other human presence where this does not interfere with local peregrine falcons to nest, lay eggs, & rear young. As possible, the area to be restricted would immediately surrounding the nest site & adjusted in location if the birds shift their nest site during the 5 year restriction period. The proposed Special Order would be lifted on or before Aug. 1, depending on the status of the nest & the peregrine falcons present, & the Special Order would remain in effect until rescinded or until 8/1/25, whichever event occurs first.
