I MIDDLE PARK SAGE GROUSE CONSERVATION PLAN I MIDDLE PARK SAGE GROUSE CONSERVATION PLAN I. PREAMBLE Greater-sage grouse (Centrocercus urophasianus) are closely associated with sagebrush rangelands throughout western North America, and occur nowhere else in the world. Over the past 75 years, distribution and abundance of this species has markedly decreased throughout its historic range. Long-term viability of sage grouse populations is highly tenuous in at least 6 of the 11 states, and the 2 Canadian provinces, where they presently occur. Uncertainty and concern for the future of sage grouse has given rise to recent efforts to assess and ensure sage grouse viability throughout its range. Should sage grouse populations continue to decline, the bird will likely be listed as federally threatened or endangered under the Endangered Species Conservation Act of 1969. If so classified, involuntary restrictions could be placed on lands where sage grouse occur or would be expected to occur. Greater-sage grouse are native to Middle Park, an intermountain basin in Grand and Summit counties, situated in north-central Colorado. The historic range of sage grouse in Middle Park has decreased over time; there is likewise concern that population numbers have correspondingly declined. Because of increased concerns about the status of sage grouse in Middle Park, a group of concerned citizens and agencies formed a working partnership in the spring of 1999, known as the Middle Park Sage Grouse Committee (hereafter referred to as MPSGC) . This group is committed to developing a conservation plan, and to undertaking actions to stabilize and maintain a healthy sage grouse population in Middle Park. II. THE PLAN AND ITS PURPOSE The Middle Park Sage Grouse Conservation Plan (Plan) provides information on the sage grouse population and its habitat in Middle Park, and addresses issues and concerns related to the possible decline of sage grouse populations in the area. The primary objective of the Plan is to maintain a healthy and viable sage grouse population in Middle Park, and to prevent any long term decline in sage grouse numbers. Both public and private lands have traditionally provided significant sage grouse habitat in Middle Park. This makes it important to protect and enhance the quality of exisiting rangelands, while preserving the historic agricultural character of the area. Efforts to maintain a healthy sage grouse population in the Middle Park area will: 1. Identify and address major threats to the health of the sagebrush-grassland plant community which serves as the basis for a viable sage grouse population. i 2. Prioritize areas in which to concentrate conservation efforts, identifying critical habitats in need of protection or enhancement, such as sage grouse winter range, nesting areas, and brood rearing habitat. 3. Identify tools to protect and improve sagebrush communities. 4. Improve sagebrush rangelands through treatments identified. 5. Measure the response of sage grouse and habitat to treatments. 6. Identify funding sources for projects and monitoring. 7. Seek provisions to secure habitat for sage grouse in land use planning. III. GUIDING PRINCIPLES The collaborative process used by MPSGC is intended to guide resource management efforts related to sage grouse through the development of goals, guidelines, and the selection of conservation actions that may cross jurisdictional boundaries and land ownership patterns. Participation in the plan by private landowners is strictly voluntary. The following principles have been adopted to guide this process: 1. Promote public involvement in planning and decision making. 2. Maintain an atmosphere of cooperation among land managers, private landowners, and other stakeholders where everyone feels free to actively participate. 3. Implement conservation actions that meet the needs of sage grouse, while promoting stability of the agricultural lifestyle in Middle Park. 4. Respect individual views and values. 5. Implement conservation actions on a collaborative basis that have broad community support. 6. Seek efficiency and integration of efforts among partners. 7. Select conservation actions that also meet other land or resource management objectives. ii Table of Contents I.

AREA DESCRIPTION Sagebrush rangelands of the upper Colorado River drainage in north-central Colorado (Figure 1) are the focus of this Plan. Portions of Grand and Summit counties are included in this area, as is the extreme northeastern corner of Eagle County. Other than the area of the Colorado River downstream from Gore Canyon (Radium/Sheephorn), lands covered by this Plan lie within Middle Park, a high elevation intermountain basin. Middle Park has a

  • Southern Rockies Lynx Linkage Areas
    Southern Rockies Lynx Amendment Appendix D - Southern Rockies Lynx Linkage Areas The goal of linkage areas is to ensure population viability through population connectivity. Linkage areas are areas of movement opportunities. They exist on the landscape and can be maintained or lost by management activities or developments. They are not “corridors” which imply only travel routes, they are broad areas of habitat where animals can find food, shelter and security. The LCAS defines Linkage areas as: “Habitat that provides landscape connectivity between blocks of habitat. Linkage areas occur both within and between geographic areas, where blocks of lynx habitat are separated by intervening areas of non-habitat such as basins, valleys, agricultural lands, or where lynx habitat naturally narrows between blocks. Connectivity provided by linkage areas can be degraded or severed by human infrastructure such as high-use highways, subdivisions or other developments. (LCAS Revised definition, Oct. 2001). Alpine tundra, open valleys, shrubland communities and dry southern and western exposures naturally fragment lynx habitat within the subalpine and montane forests of the Southern Rocky Mountains. Because of the southerly latitude, spruce-fir, lodgepole pine, and mixed aspen-conifer forests constituting lynx habitat are typically found in elevational bands along the flanks of mountain ranges, or on the summits of broad, high plateaus. In those circumstances where large landforms are more isolated, they still typically occur within 40 km (24 miles) of other suitable habitat (Ruggerio et al. 2000). This distribution maintains the potential for lynx movement from one patch to another through non-forest environments. Because of the fragmented nature of the landscape, there are inherently important natural topographic features and vegetation communities that link these fragmented forested landscapes of primary habitat together, providing for dispersal movements and interchange among individuals and subpopulations of lynx occupying these forested landscapes.

Differences between no use and varying 19 degrees of snowmobile use (low, medium and high) on shallow (the operational standard of 30 20 cm) and deeper snowpacks (120 cm) were quantified and statistically assessed using 21 measurements of snow density, temperature, stratigraphy, hardness, and ram resistance from 22 snow pit profiles.

Zirkel Wilderness, Routt National Forest, Jackson County, Colorado We drove from home, I-70 to CO-9, to Kremling, Colorado. We turned west on US-40 to CO-14 at Muddy Pass, and traveled east on CO-14 to Hebron. At Hebron we found County Rd 24 and followed it southwest and then west about 8 miles to County Rd 5. We then went north and northeast about 7 miles to County Rd 22. We took County Rd 22 about 4 miles west and southwest to an unnumbered road. At that junction is a bunch of mailboxes for the cabins along the road up to the Rainbow Lake trailhead. About three miles up the road is the parking area and trailhead for Forest Trail 1130, or the Rainbow Lake Trail. The drive takes about 3 hours. It took us over four hours. About 3 miles in on County Road 22 an unmarked dirt road veers left, directly east, down and along the face of a steep hill into the valley on the right. The road is marked as the public access route. We took it and followed the road and public access signs into and through a farmer’s cattle corral, opening and closing his gates at each end, then around a hill north and then east to the end of the road. At the end of the road was a bare wooden platform that looked like at one time it would be the floor for a cabin.
