Rockefeller, Jr. Memorial Parkway(Colorado State University. Libraries, 2025-06) Lemly, Joanna M., author; Laughlin, Lauren, author; Smith, Gabrielle A., author; National Park Service (Fort Collins, Colo.), publisherFens are groundwater-fed, peat-accumulating wetlands that form where the accumulation of organic material exceeds decomposition. While fens are common at northern latitudes, fens in the Rocky Mountains are relatively rare, small features that support numerous rare plant species. Little is known about fens in Grand Teton National Park (GRTE) and John D. Rockefeller, Jr. Memorial Parkway (JODR). While GRTE and JODR are managed for natural resource preservation and recreation, the parks have a history of other land uses and have seen increasing visitors in recent years. To better manage fen resources in GRTE and JODR, the National Park Service funded the Colorado Natural Heritage Program to create a map of potential fens within GRTE and JODR, visit potential fen polygons to verify their status as fens, and survey for rare fen-indicator plant species. The initial map of fens created in the winter of 2022-23 contained 906 potential fens covering 5,208 acres. Field sampling in the summer of 2023 verified 41 fens and 28 peat-accumulating wetlands. The revised map contained 1,016 acres of confirmed or highly likely fens, which were concentrated at elevations below 2,100 m in specific areas of the parks, including Lower Jackson Lake watershed and most of JODR. One hundred and twenty-seven populations of 23 rare fen-indicator plant species were observed either within or near confirmed fens. Rapid vegetation surveys were conducted in 38 confirmed fens. Most were basin fens, several of which contained floating mats, and seven sites were sloping fens. Vegetation composition was overwhelmingly native and indicative of excellent condition. Most sites were dominated by graminoids, specifically sedge (Carex) species, and some sites also contained willows (Salix spp.) and other low shrubs. Quantitative vegetation sampling was carried out in five sites for more precise estimates of species cover. Water chemistry measurements of pH and specific conductance were collected in the field at most sites, and water chemistry samples were collected at five sites for more detailed lab analysis. Water pH ranged from 4.86-8.65 and specific conductance ranged from 1 1105 μS/cm. Most fens were characterized as rich fens, with some considered poor fens and no sites meeting the water chemistry and vegetation classification of extreme rich fen. GRTE and JODR fens are exceptional resources that support numerous rare species. Management plans for the park units should protect and avoid impacting these special habitats and their species so they remain intact into the future.Item Open Access Inventory of fens in White River National Forest.

Libraries, 2021-03) Sovell, John, author; Colorado Natural Heritage Program, publisherThe primary objective of the monitoring effort is to compare skipper use (measured by the number of adult butterflies seen within a known area) of untreated lower montane forest with butterfly use in lower montane forest that has been thinned to reduce fire danger, which is expected to improve Pawnee montane skipper habitat.Item Open Access Pawnee montane skipper vegetation study for the Upper South Platte watershed protection and restoration project, September 2012(Colorado State University. Libraries, 2014-10) Sovell, John, author; Colorado Natural Heritage Program, publisherThe Pawnee montane skipper (Hesperia leonardus montana) (PMS) is listed as Threatened under the Endangered Species Act. To assist in evaluating the effects of forest restoration treatments, the USFS, USFWS, and Denver Water sponsored a monitoring program for the PMS. Annual monitoring began in August 2000, was conducted through 2013, and will continue into the future. Three forest restoration treatment areas (2000 treatment, 2002 treatment, and 2004 treatment) and a control area were designated for monitoring. The primary objective of monitoring is to compare skipper use of untreated lower montane forest with use in lower montane forest that has been thinned to reduce fire danger and that is expected to improve PMS habitat.Item Open Access Rocky Mountain National Park, Colorado 2001-2005 vegetation classification and mapping(Colorado State University.

Technical Service Center, publisherRocky Mountain National Park (ROMO) encompasses 417 square miles in north central Colorado, and lies on the eastern slope of the southern Rocky Mountains. This mapping effort is part of the National Park Services' national inventory and monitoring program and will provide core or "baseline" information that park managers need to effectively manage and protect park resources. This vegetation inventory was conducted in accordance with specified protocols and quality assurance standards.Item Open Access Sand Creek Massacre National Historic Site vegetation classification and mapping: a report for the Southern Plains Network(Colorado State University.

Libraries, 2016-04) Smith, Pamela, author; Greenwell, Amy Lavender, author; Colorado Natural Heritage Program, publisherNine species of state listed noxious weeds were mapped at PCD in 2015 and assessed for their threat level based on coverage, plant biology, surrounding land use and their potential to spread. The use of repeatable data is important to facilitate comparisons of weed populations over time. This report and the spatial dataset will provide a useful tool to develop weed mitigation strategies and invasive species control plans to comply with noxious weed regulations.Item Open Access Noxious weed survey of Peterson Air Force Base - 2014(Colorado State University. Libraries, 2014-12) Rondeau, Renée, author; Lavender-Greenwell, Amy, author; Colorado Natural Heritage Program, publisherIn the summer of 2014, the Colorado Natural Heritage Program (CNHP) mapped noxious weeds at Peterson Air Force Base (PAFB) east of Colorado Springs, Colorado. This was the second sample year, with 2003 the first (Anderson et al. 2003). The project was undertaken to provide the PAFB Natural Resources Manager with information contributing to the development of a formal Integrated Weed Management Plan ... Thirteen species of weeds were assessed on PAFB, one on the A list, eight on the B list, three on the C list and one on the watch list. Since the 2003 survey, three species increased, two were stable, three decreased, three were eradicated and two new species on the state noxious weed list were observed. (Source: Executive summary.)
