The 2012 U.S. Forest Service Planning Rule defines Species of Conservation Concern (SCC) as “a species, other than federally recognized threatened, endangered, proposed, or candidate species, that is known to occur in the plan area and for which the regional forester has determined that the best available scientific information indicates substantial concern about the species' capability to persist over the long-term in the plan area” (36 CFR 219.9). This overview was developed to summarize information relating to this species’ consideration to be listed as a SCC on the Rio Grande National Forest, and to aid in the development of plan components and monitoring objectives. 3.

PEAK to PRAIRIE: BOTANICAL LANDSCAPES of the PIKES PEAK REGION Tass Kelso Dept of Biology Colorado College 2012

Mt. Olympus, mythological home of the Greek gods, Yosemite’s Half Dome, the ever-classic Matterhorn, Alaska’s Denali, and Colorado’s Pikes Peak all share the quality of compelling attraction that a charismatic alpine profile evokes. At the base of our peak along the confluence of two small, nondescript streams, Native Americans gathered thousands of years ago. Explorers, immigrants, city-visionaries and fortune-seekers arrived successively, all shaping in turn the region and communities that today spread from the flanks of Pikes Peak. From any vantage point along the Interstate 25 corridor, the Colorado plains, or the Arkansas River Valley escarpments, Pikes Peak looms as the dominant feature of a diverse “bioregion”, a geographical area with a distinct flora and fauna, that stretches from alpine tundra to desert grasslands. “Biodiversity” is shorthand for biological diversity: a term covering a broad array of contexts from the genetics of individual organisms to ecosystem interactions. The news tells us daily of ongoing threats from the loss of biodiversity on global and regional levels as humans extend their influence across the face of the earth and into its sustaining processes. On a regional level, biologists look for measures of biodiversity, celebrate when they find sites where those measures are high and mourn when they diminish; conservation organizations and in some cases, legal statutes, try to protect biodiversity, and communities often struggle to balance human needs for social infrastructure with desirable elements of the natural landscape. -
Denudation History and Internal Structure of the Front Range and Wet Mountains, Colorado, Based on Apatite-Fission-Track Thermoc

Kelley and Charles E. Chapin 2New Mexico Bureau of Geology and Mineral Resources, New Mexico Institute of Mining and Technology, Socorro, NM 87801 Abstract An apatite fissiontrack (AFT) partial annealing zone (PAZ) that developed during Late Cretaceous time provides a structural datum for addressing questions concerning the timing and magnitude of denudation, as well as the structural style of Laramide deformation, in the Front Range and Wet Mountains of Colorado. AFT cooling ages are also used to estimate the magnitude and sense of dis placement across faults and to differentiate between exhumation and faultgenerated topography. AFT ages at low elevationX along the eastern margin of the southern Front Range between Golden and Colorado Springs are from 100 to 270 Ma, and the mean track lengths are short (10–12.5 µm). Old AFT ages (> 100 Ma) are also found along the western margin of the Front Range along the Elkhorn thrust fault. In contrast AFT ages of 45–75 Ma and relatively long mean track lengths (12.5–14 µm) are common in the interior of the range. The AFT ages generally decrease across northwesttrending faults toward the center of the range. The base of a fossil PAZ, which separates AFT cooling ages of 45– 70 Ma at low elevations from AFT ages > 100 Ma at higher elevations, is exposed on the south side of Pikes Peak, on Mt. -

The journal was patterned after the journal Radiocarbon and covered isotopic age-dating (except carbon-14) on rocks and minerals from the Western Hemisphere. Initially, the geographic scope of papers was restricted to the western half of the United States, but was later expanded. The journal was sponsored and staffed by the New Mexico Bureau of Mines (now Geology) & Mineral Resources and the Nevada Bureau of Mines & Geology.

Chapter 4 the Denver Mountain Parks System 56
Chapter 4 The Denver Mountain Parks System 56 The Denver Mountain Parks System The Denver Mountain Parks The System 57 Chapter 4 The Denver Mountain Parks System 4.A. Systemwide Recommendations Recreation Recommendations Background Today, those who visit the Denver Mountain Parks (DMP) represent a broad cross section of people in demographics, where they reside, and how far they travel to enjoy these mountain lands. Visitors to the Mountain Parks are cosmopolitan – a true mix of cultures and languages. With the exception of African-Americans being under- represented, the Mountain Parks reflect the same diversity of age and ethnicity as occurs at Denver’s urban parks. Although visitors to the Mountain Parks represent the spectrum, many come from low to middle income households. Typically one third of those who visit either a Denver Mountain Park or another county open space park are Denver residents. Another third reside in the county in which the park is located. The last third are visitors from other counties along the Front Range, visitors from other parts of the state and nation, and international visitors. Together, mountain open space lands owned by Denver, Jefferson County, Douglas County, and Clear Creek County are used recipro- cally. Together, they are a regional Front Range open space sys- tem where each county provides its own lands and facilities for the enjoyment of its own residents, recognizing that these lands are also enjoyed by all visitors. The goal for Denver Mountain Parks is to provide the amenities and programs that take advantage of but do not diminish the valu- Red Rocks Park able natural and cultural resources and that meet today’s recre- ation needs and desire to connect kids with nature. -
