  • Western Juniper Expansion on Adjacent Disturbed and Near-Relict Sites
    Western juniper expansion on adjacent disturbed and near-relict sites By: Peter T. Soulé and Paul A. Knapp Soulé, P.T., and Knapp, P.A. (1999) Western juniper expansion on adjacent disturbed and near-relict sites. Journal of Range Management 52(5):525-533. Made available courtesy of Society for Range Management: http://www.rangelands.org/ ***Reprinted with permission. No further reproduction is authorized without written permission from the Society for Range Management. This version of the document is not the version of record. Figures and/or pictures may be missing from this format of the document.*** Abstract: We determined rates of western juniper (Juniperus occidentalis spp. occidentalis Hook.) density and cover change during the period 1951 to 1994 at 3 adjacent sites with nearly identical elevation, slope, aspect, soils, plant communities, and climate, but different land-use histories. The 3 sites are located in central Oregon at the confluence of the Deschutes and Crooked Rivers. Two of the sites are typical of central Oregon rangelands in that they have a history of anthropogenic disturbance including active fire suppression and domestic livestock grazing. The third site is a relict mesa that is a protected Research Natural Area and has experienced minimal anthropogenic impacts. We used large scale aerial photography to determine cover and density of western juniper in 1951, 1956, 1961, 1972, 1982, and 1994. We found that western juniper density and cover during the last 4 decades increased at all sites, with changes on the relict site similar to those on one of the disturbed sites. We suggest that even though 2 of the traditionally cited causes of western juniper expansion since the late 1800s (altered fire regimes, domestic livestock grazing) may have contributed to expansion on our disturbed sites, these mechanisms can not explain expansion on the near-relict mesa.

Land and Resource Management Plan Preface Crooked River National Grassland August 1989 The Crooked River National Forest Land and Resource Management Plan (Grassland Plan) was prepared in compliance with 36 CFR 219, based on the Forest and Rangeland Renewable Resources Planning Act (RPA) as amended by the National Forest Management Act of 1976, and in compliance with 40 CFR 1500 based on the National Environmental Policy Act of 1969. Because the Plan is a major Federal action significantly affecting the quality of the human environment, an environmental impact statement (EIS) was pre- pared The Plan provides direction for implementing the preferred alternative selected in the EIS. If any particular provision of this Grassland Plan, or the application of the action to any person or circumstance,is found to beinvalid, the remainder of the Forest Plan and the application of that provision to other persons or circumstances shall not be affected.

    Bull Trout Final Critical Habitat Justification: Rationale for Why Habitat is Essential, and Documentation of Occupancy Chapter 6. Coastal Recovery Unit—Lower Deschutes River Critical Habitat Unit 253 Bull Trout Final Critical Habitat Justification Chapter 6 U. S. Fish and Wildlife Service September 2010 Chapter 6. Lower Deschutes River Critical Habitat Unit The Lower Deschutes River CHU is essential to the conservation of bull trout because populations here are genetically diverse; have diverse life history expressions including fluvial, adfluvial, and resident populations with extensive connectivity within and outside the CHU; and are the most robust in this part of the Mid-Columbia RU. The Deschutes River basin contains a variety of representative habitats, including high Cascade headwater streams, glacially fed streams, spring systems, lake habitat, and mainstem river habitat. Maintaining and recovering these populations will ensure conservation of adaptations to these unique habitats, and adequate redundancy within this basin and relative to adjacent core areas (e.g., Hood River, John Day River, etc.). Protecting and maintaining all five of the Deschutes River basin’s bull trout populations will help ensure the long-term viability of these bull trout by protecting a geographically widespread distribution of unique but related bull trout (see Appendix 1 for more detailed information). The Lower Deschutes River Critical Habitat Unit is located in Wasco, Sherman, Jefferson, Deschutes, and Crook counties in central Oregon. The Deschutes River basin contains a variety of representative habitats including high Cascade headwater streams, glacially fed streams, spring systems, lakes, and mainstem river habitat. The Confederated Tribes of the Warm Springs Reservation (CTWS) own lands in this CHU.

The purpose of the statement is to disclose the probable environmental impacts for consideration along with economic and technical information in the decisionmaking process. Comments concerning the adequacy of this statement will be considered in the preparation of the final environmental impact statement. The comment period will end June Informal discussion sessions intended to assist you in reviewing and commenting on the draft EIS will be held at 7:00 p.m., May 251982, at St. Joseph’s Parish Hall, 150 East First St., Prineville, Oregon and at 7:00 p.m., May 26, 1982, at the Bend Riverhouse Motor Inn, 3075 North Highway 97, Bend, Oregon. Bureau of Land Management personnel will be available at both sessions to answer questions regarding the draft EIS analysis. The draft EIS may be incorporated into the final EIS by reference only. The final EIS then would consist of public comments and responses and any needed changes of the draft. Therefore, please retain this Draft EIS for use with the final. Comments received after the close of the comment period will be considered in the decision process, even though they may be too late be specifically addressed in the final environmental impact statement.

  • Mountain Quail Translocations in Eastern Oregon
    MOUNTAIN QUAIL TRANSLOCATIONS IN EASTERN OREGON Project Report: 2003 Rick Vetter 03 Michael Pope1, Faculty Research Associate Oregon State University Greg Jackle, Wildlife Biologist Oregon Department of Fish and Wildlife Dave Budeau, Upland Game Bird Program Coordinator Oregon Department of Fish and Wildlife Dave Zalunardo, Wildlife Biologist Ochoco National Forest Contact Information: 1104 Nash Hall, Department of Fisheries and Wildlife, Oregon State University, Corvallis, OR 97331 Ph: 541-737-4908 Email: [email protected] 2 Executive Summary Mountain Quail populations have declined in many areas of the western Great Basin, particularly across former ranges in southeastern Washington, western Idaho, and eastern Oregon. Strategies for restoring declining wildlife populations have been largely reactive with recovery programs typically initiated only after populations or suitable habitats reached critically low levels. Restoration plans were often implemented without a clear understanding of the life-history or habitat requirements of a species. Griffith et al. (1989) suggested conducting research and testing restoration techniques on species before populations reached crisis levels. Mountain Quail are an excellent candidate for translocations given the criteria proposed by Griffith et al. (1989). This species is highly productive with large clutches (10-12 eggs/clutch), and has a highly varied, mostly herbivorous diet. Currently, western Oregon has abundant and easily accessible populations of Mountain Quail that could be a source for re-establishing or supplementing populations in areas of eastern Oregon where populations are rare or have been extirpated. In 2001, the Oregon Department of Fish and Wildlife, the U.S. Forest Service, and the Game Bird Program at Oregon State University initiated a Mountain Quail translocation and research program for eastern Oregon.
