Mojave National Preserve Management Plan for Developed
Mojave National Preserve—Management Plan for Developed Water Resources CHAPTER 3: AFFECTED ENVIRONMENT Introduction This chapter describes the unique factors that influence water resource management in the Preserve and the resources that could be affected by the implementation of any of the alternatives described in Chapter 2: Alternatives. The resource descriptions provided in this chapter serve as a baseline to compare the potential effects of the management actions proposed in the alternatives. The following resource topics are described in this chapter: • Environmental Setting • Cultural Resources • Water Resources • Wilderness Character • Wildlife Environmental setting and water resources are important for context and are foundational for water resource management, but are not resources that are analyzed for effects. Resource issues that were considered and dismissed from further analysis are listed in Chapter 1: Purpose of and Need for Action and are not discussed further in this EA. A description of the effects of the proposed alternatives on wildlife, cultural resources, and wilderness character is presented in Chapter 4: Environmental Consequences. Environmental Setting The Preserve includes an ecologically diverse yet fragile desert ecosystem consisting of vegetative attributes that are unique to the Mojave Desert, as well as components of the Great Basin and Sonoran Deserts. Topography The topography of the Preserve is characteristic of the mountain and basin physiographic pattern, with tall mountain ranges separated by corresponding valleys filled with alluvial sediments. Primary mountain ranges in the Preserve, from west to east, include the Granite, Kelso, Providence, Clark, New York, and Piute Mountains. Major alluvial valleys include Soda Lake (dry lake bed), Shadow Valley, Ivanpah Valley, Lanfair Valley, and Fenner Valley. -

Potential Impacts of Proposed Solar Energy Development Near the South Soda Mountains on Desert Bighorn Sheep Connectivity
1 Potential impacts of proposed solar energy development near the South Soda Mountains on desert bighorn sheep connectivity Clinton W. Epps1, John D. Wehausen2, Ryan J. Monello3, and Tyler G. Creech1 1Department of Fisheries and Wildlife, 104 Nash Hall, Oregon State University, Corvallis, OR 2White Mountain Research Station, University of California 3National Park Service, Biological Resource Management Division 25 February 2013 Report to the California Department of Fish and Wildlife, National Park Service, and Bureau of Land Management Summary This report evaluates implications of the proposed renewable energy project in the vicinity of the Soda Mountains relative to conservation of desert bighorn sheep (Ovis canadensis nelsoni) in the Mojave Desert of California. The proposed solar array would straddle Interstate 15 and cover areas between the North and South Soda Mountains, on the northwest edge of the Mojave National Preserve. Although the exact footprint of the project is not yet clear, the intensity of development within such solar arrays would likely prevent movement of bighorn sheep through project areas. Past bighorn sheep movement between the North and South Soda has been blocked by Interstate 15. However, restoration of this movement corridor may be possible by either 1) modifying existing locations where the Interstate crosses washes via bridges to create potential underpasses for bighorn sheep by enticing bighorn sheep to those areas, or 2) construction of an overpass structure as has been implemented successfully over Highway 93 in Arizona. To determine the importance of the affected area for restoration of bighorn sheep connectivity, we used network analysis of an empirically-derived connectivity model for desert bighorn sheep to evaluate short- and long-term consequences of restoring the Soda Mountains connection for gene flow and recolonization by desert bighorn sheep. -
Late Quaternary Stratigraphy and Luminescence Geochronology of the Northeastern Mojave Desert
ARTICLE IN PRESS Quaternary International 166 (2007) 61–78 Late Quaternary stratigraphy and luminescence geochronology of the northeastern Mojave Desert Shannon A. Mahana,Ã, David M. Millerb, Christopher M. Mengesc, James C. Younta aUnited States Geological Survey, Box 25046 MS 974, Denver, CO 80225, USA bUnited States Geological Survey, 345 Middlefield Road, MS 973, Menlo Park, CA 94025, USA cUnited States Geological Survey, 520 N. Park Ave., Tucson, AZ 85719-5035, USA Available online 8 January 2007 Abstract The chronology of the Holocene and late Pleistocene deposits of the northeastern Mojave Desert have been largely obtained using radiocarbon ages. Our study refines and extends this framework using optically stimulated luminescence (OSL) to date deposits from Valjean Valley, Silurian Lake Playa, Red Pass, and California Valley. Of particular interest are eolian fine silts incorporated in ground- water discharge (GWD) deposits bracketed at 185–140 and 20–50 ka. Alluvial fan deposits proved amenable for OSL by dating both eolian sand lenses and reworked eolian sand in a matrix of gravel that occurs within the fan stratigraphy. Lacustrine sand in spits and bars also yielded acceptable OSL ages. These OSL ages fill gaps in the geochronology of desert deposits, which can provide data relevant to understanding the responses of several depositional systems to regional changes in climate. This study identifies the most promising deposits for future luminescence dating and suggests that for several regions of the Mojave Desert, sediments from previously undated landforms can be more accurately placed within correct geologic map units.

Is There Any Evidence of Mega-Lake Manly in the Eastern Mojave Desert During Oxygen Isotope Stage 5E/6?
Quaternary Research 57, 177–179 (2002) doi:10.1006/qres.2001.2299, available online at http://www.idealibrary.com on REPLY Is There Any Evidence of Mega-Lake Manly in the Eastern Mojave Desert during Oxygen Isotope Stage 5e/6? I am pleased to have the opportunity to defend and clarify the implication that Ku’s dates are more reliable than those of my hypothesis regarding the extent of the Blackwelder stand of Hooke and Lively (see Hooke and Dorn, 1992) is debatable, Lake Manly during marine oxygen isotope stage 6 (OS6). Let given that both use the -counting technique and thus may suffer me start by addressing a couple of general points. from problems with U migration. First, with reference to the pejorative prefix “mega” in Enzel Salt Spring Hills shoreline. Enzel et al. maintain that this et al.’s comment, let me put the size of the lake under discussion shoreline is cut into colluvium and, at its southeastern end, into in perspective. If water were to fill Death Valley to the 90-m alluvial fan deposits. I agree with the former. On the other hand, level today, the surface area would be 1600 km2 (Meek, 1997), air photos, a map in Anderson and Wells (1997), and my own whereas the area Hale proposed, based on overflow at Ash Hill observations do not support the interpretation that it is cut into an pass, would have been 8000 km2 (Hale, 1985). The surface alluvial fan at its southeastern end. Even if further study shows area of the OS6 lake proposed in my paper is 2800 km2, less that it is, however, Enzel et al.’s statements about the age of than half the size of Hale’s lake and less than twice the size a the fan unit are misleading (1) because they are based on dates 90-m lake would have were it to occupy the valley today. -
Biological Goals and Objectives
Appendix C Biological Goals and Objectives Draft DRECP and EIR/EIS APPENDIX C. BIOLOGICAL GOALS AND OBJECTIVES C BIOLOGICAL GOALS AND OBJECTIVES C.1 Process for Developing the Biological Goals and Objectives This section outlines the process for drafting the Biological Goals and Objectives (BGOs) and describes how they inform the conservation strategy for the Desert Renewable Energy Conservation Plan (DRECP or Plan). The conceptual model shown in Exhibit C-1 illustrates the structure of the BGOs used during the planning process. This conceptual model articulates how Plan-wide BGOs and other information (e.g., stressors) contribute to the development of Conservation and Management Actions (CMAs) associated with Covered Activities, which are monitored for effectiveness and adapted as necessary to meet the DRECP Step-Down Biological Objectives. Terms used in Exhibit C-1 are defined in Section C.1.1. Exhibit C-1 Conceptual Model for BGOs Development Appendix C C-1 August 2014 Draft DRECP and EIR/EIS APPENDIX C. BIOLOGICAL GOALS AND OBJECTIVES The BGOs follow the three-tiered approach based on the concepts of scale: landscape, natural community, and species. The following broad biological goals established in the DRECP Planning Agreement guided the development of the BGOs: Provide for the long-term conservation and management of Covered Species within the Plan Area. Preserve, restore, and enhance natural communities and ecosystems that support Covered Species within the Plan Area. The following provides the approach to developing the BGOs. Section C.2 provides the landscape, natural community, and Covered Species BGOs. Specific mapping information used to develop the BGOs is provided in Section C.3. -
