A quantum leap was taken somewhere in 2016-17 when Kevin Browne introduced me to Google Scholar – and we were off to the races. Elaine Tulving deserves a special mention for her assistance in dealing with formatting issues, keeping printers working, filing hard copies, ignoring occasional foul language – occasionally falling prey to it herself, and occasionally livening things up with an exclamation of “oh come on now, you just made that word up!” Bob Theriault assisted in many ways and now has a lifetime job, if he wants it, entering these references into Zotero.

  • North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave
    North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave http://www.desertusa.com/desert.html In most modern classifications, the deserts of the United States and northern Mexico are grouped into four distinct categories. These distinctions are made on the basis of floristic composition and distribution -- the species of plants growing in a particular desert region. Plant communities, in turn, are determined by the geologic history of a region, the soil and mineral conditions, the elevation and the patterns of precipitation. Three of these deserts -- the Chihuahuan, the Sonoran and the Mojave -- are called "hot deserts," because of their high temperatures during the long summer and because the evolutionary affinities of their plant life are largely with the subtropical plant communities to the south. The Great Basin Desert is called a "cold desert" because it is generally cooler and its dominant plant life is not subtropical in origin. Chihuahuan Desert: A small area of southeastern New Mexico and extreme western Texas, extending south into a vast area of Mexico. Great Basin Desert: The northern three-quarters of Nevada, western and southern Utah, to the southern third of Idaho and the southeastern corner of Oregon. According to some, it also includes small portions of western Colorado and southwestern Wyoming. Bordered on the south by the Mojave and Sonoran Deserts. Mojave Desert: A portion of southern Nevada, extreme southwestern Utah and of eastern California, north of the Sonoran Desert. Sonoran Desert: A relatively small region of extreme south-central California and most of the southern half of Arizona, east to almost the New Mexico line.

  • Sonny Bono Salton Sea National Wildlife Refuge Complex
    Appendix J Cultural Setting - Sonny Bono Salton Sea National Wildlife Refuge Complex Appendix J: Cultural Setting - Sonny Bono Salton Sea National Wildlife Refuge Complex The following sections describe the cultural setting in and around the two refuges that constitute the Sonny Bono Salton Sea National Wildlife Refuge Complex (NWRC) - Sonny Bono Salton Sea NWR and Coachella Valley NWR. The cultural resources associated with these Refuges may include archaeological and historic sites, buildings, structures, and/or objects. Both the Imperial Valley and the Coachella Valley contain rich archaeological records. Some portions of the Sonny Bono Salton Sea NWRC have previously been inventoried for cultural resources, while substantial additional areas have not yet been examined. Seventy-seven prehistoric and historic sites, features, or isolated finds have been documented on or within a 0.5- mile buffer of the Sonny Bono Salton Sea NWR and Coachella Valley NWR. Cultural History The outline of Colorado Desert culture history largely follows a summary by Jerry Schaefer (2006). It is founded on the pioneering work of Malcolm J. Rogers in many parts of the Colorado and Sonoran deserts (Rogers 1939, Rogers 1945, Rogers 1966). Since then, several overviews and syntheses have been prepared, with each succeeding effort drawing on the previous studies and adding new data and interpretations (Crabtree 1981, Schaefer 1994a, Schaefer and Laylander 2007, Wallace 1962, Warren 1984, Wilke 1976). The information presented here was compiled by ASM Affiliates in 2009 for the Service as part of Cultural Resources Review for the Sonny Bono Salton Sea NWRC. Four successive periods, each with distinctive cultural patterns, may be defined for the prehistoric Colorado Desert, extending back in time over a period of at least 12,000 years.

It was conceived of your interests and concerns, born into law through your elected representatives, molded by your direct personal involvement, matured and refined through public conflict, interaction, and compromise, and completed as a result of your review, comment and advice. It is a good plan. You have reason to be proud. Perhaps, as individuals, we may say, “This is not exactly the plan I would like,” but together we can say, “This is a plan we can agree on, it is fair, and it is possible.” This is the most important part of all, because this Plan is only a beginning. A plan is a piece of paper-what counts is what happens on the ground. The California Desert Plan encompasses a tremendous area and many different resources and uses. The decisions in the Plan are major and important, but they are only general guides to site—specific actions. The job ahead of us now involves three tasks: —Site-specific plans, such as grazing allotment management plans or vehicle route designation; —On-the-ground actions, such as granting mineral leases, developing water sources for wildlife, building fences for livestock pastures or for protecting petroglyphs; and —Keeping people informed of and involved in putting the Plan to work on the ground, and in changing the Plan to meet future needs.

The Bureau of Land Management (BLM) prepared the PAiFEIS in consultation with cooperating agencies, taking into account public comments received during the National Environmental Policy Act (NEPA) process. The proposed decision on the plan amendment would add the GSEP site to those identified in the current COCA Plan, as amended, for solar energy production. The preferred alternative on the GSEP is to approve the dry cooling alternative to the right-of-way grant applied for by Genesis Solar, LLC. This PAIFEIS for the GSEP has been developed in accordance with NEPA and the Federal Land Policy and Management Act of 1976. The PA is largely based on the preferred alternative in the Draft Resource Management Plan·AmendmentlDraft Environmentallmpact Statement (DRMP-AiDEIS), which was released on April 9, 2010. The PAIFEIS for the GSEP contains the proposed plan and project description, a summary of changes made between the DRMP·AlDEIS and PRMP-AiFEIS, an analysis of the impacts of the decisions, a summary ofwritten comments received during the public review period for the DRMP­ AlDEIS and responses to comments.

  • Flat-Tailed Horned Lizard Rangewide Management Strategy, 2002 Revision
    Flat-tailed Horned Lizard Rangewide Management Strategy, 2003 Revision An Arizona-California Conservation Strategy Prepared and edited by the Flat-tailed Horned Lizard Interagency Coordinating Committee May 2003 EXECUTIVE SUMMARY The Flat-tailed Horned Lizard Rangewide Management Strategy has been prepared to provide guidance for the conservation and management of sufficient habitat to maintain extant populations of flat-tailed horned lizards (FTHLs), Phrynosoma mcallii, in each of five Management Areas (MAs) in perpetuity. The species is found only in southwestern Arizona, southeastern California, and adjacent portions of Sonora and Baja California Norte, Mexico. The USFWS proposed the species for listing as a threatened species on November 29, 1993. Human activities have resulted in the conversion of roughly 49% of the historic FTHL habitat to other uses, such as agriculture and urban development. Further evaluation of populations supported by remaining habitat is necessary. While initial evidence suggested that FTHL populations had declined in the Yuha Basin and northern East Mesa (Wright 1993; USFWS 1993), Wright (2002) recently found no significant trends in lizard encounter rates in Yuha Desert, East Mesa, or West Mesa from 1979-2001. The USFWS withdrew its proposed listing on January 3, 2003, based in part on protections offered by this Rangewide Management Strategy (RMS). The 1997 edition of the RMS established five FTHL MAS — four in California and one in Arizona. Surface disturbing activities are limited in these areas. Although land alterations in FTHL habitat outside of the MAs are not limited, mitigation and compensation measures are applied. One research area (RA) was also established to support research in an active off-highway vehicle (OHV) recreation area.
