Refurbishing the Carousel Irrigation System
p REFURBISHING THE CAROUSEL IRRIGATION SYSTEM Marcello Nicoletti, Christina Steele, Mason Kolb Isa Bar-On, Advisor Buki Katz, Sponsor February 24, 2019 This report presents the work of WPI undergraduate students submitted to the faculty as evidence of completion of a degree requirement. WPI routinely publishes these reports on its website without editorial or peer review. For more information about the projects program at WPI, please see https://www.wpi.edu/academics/ugradstudies/project-learning.html Page | 1 Abstract This project aimed to refurbish the Southern Arava Research and Development Station’s non-functioning Carousel Irrigation System. We assessed each subsystem and completed a full system analysis to identify problem areas. This team was able to repair and suggest improvements to this machine, which enables the R&D Station with the power that will increase the success of local farmers in the global produce market. Page | 2 Acknowledgements This project would not have been possible without the opportunity provided to us by Buki Katz, manager of the Arava Research and Development Station. In addition, we would like to thank everyone else at the Station for always providing answers to our questions, especially Ehud Zeelim, Gilad Hurvits, and Daryl Gillett. Repairing the Carousel Irrigation System was made possible with the support Crystal Vision’s Ra’anan Shema and Muki Telman. Without their support, this project would not have reached its current level of success. We would also like to thank Professor Isa Bar-On for advising this project. Her steady guidance and thoughtful suggestions kept our group moving forward with new possibilities and ideas. -
Mammals of the California Desert
MAMMALS OF THE CALIFORNIA DESERT William F. Laudenslayer, Jr. Karen Boyer Buckingham Theodore A. Rado INTRODUCTION I ,+! The desert lands of southern California (Figure 1) support a rich variety of wildlife, of which mammals comprise an important element. Of the 19 living orders of mammals known in the world i- *- loday, nine are represented in the California desert15. Ninety-seven mammal species are known to t ':i he in this area. The southwestern United States has a larger number of mammal subspecies than my other continental area of comparable size (Hall 1981). This high degree of subspeciation, which f I;, ; leads to the development of new species, seems to be due to the great variation in topography, , , elevation, temperature, soils, and isolation caused by natural barriers. The order Rodentia may be k., 2:' , considered the most successful of the mammalian taxa in the desert; it is represented by 48 species Lc - occupying a wide variety of habitats. Bats comprise the second largest contingent of species. Of the 97 mammal species, 48 are found throughout the desert; the remaining 49 occur peripherally, with many restricted to the bordering mountain ranges or the Colorado River Valley. Four of the 97 I ?$ are non-native, having been introduced into the California desert. These are the Virginia opossum, ' >% Rocky Mountain mule deer, horse, and burro. Table 1 lists the desert mammals and their range 1 ;>?-axurrence as well as their current status of endangerment as determined by the U.S. fish and $' Wildlife Service (USWS 1989, 1990) and the California Department of Fish and Game (Calif. -
The Imperial Valley Is Located About 150 Miles Southeast of Los Angeles
The Imperial Valley is located about 150 miles southeast of Los Angeles. It is a section of a much larger geologic structure -- the Salton Trough -- which is about 1,000 miles in length. The structure extends from San Gorgonio Pass southeast to the Mexican border, including the Gulf of California and beyond the tip of the Baja California Peninsula. The surrounding mountains are largely faulted blocks of the Southern California batholith of Mesozoic age, overlain by fragments of an earlier metamorphic complex. The valley basin consists of a sedimentary fill of sands and gravels ranging up to 15,000 feet in thickness. The layers slope gently down-valley, and contain several important aquifers. The valley is laced with major members of the San Andreas Fault system. Minor to moderate earthquake events are common, but severe shocks have not been experienced in recorded history. The entire trough, including the Gulf is an extension of the East Pacific Rise, a zone of separation in Earth's crust. Deep sea submergence instruments have observed many phenomena of crustal formation. The axis of the Rise, hence of the Salton Valley as well, is a great transform fault that is having the effect of separating an enormous slab of North America, consisting of the Baja Peninsula and coastal California away from the mainland, with movement to the northwest and out to sea as a terranne.

Cover Crops for High-Desert Farming Systems in Idaho
BULLETIN 889 Cover Crops for High-Desert Farming Systems in Idaho Lauren Hunter, Christi Falen, and Amber Moore Introduction A cover crop is any crop grown to provide living ground cover. It can be planted with the main crop or in rotation with it. Growing cover crops is a best management practice to help minimize soil erosion, prevent nutrient leaching, provide nitrogen (N) for subsequent cash crops, suppress weeds, sequester carbon, increase crop diversity, and provide beneficial insect habitats. In Idaho, cover crops can be planted in spring, summer, or fall and rotated with a variety of crops, including barley, alfalfa, potato, sugar beets, beans, and vegetables. By planting cover crops, Idaho producers benefit from Figure 1. A cover crop mixture of canola, triticale, clover, and vetch the following: helps to scavenge nutrients, increase organic matter, fix N, and control weeds.

Distribution and Seasonal Movements of Bendire's Thrasher in California
WESTERN BIRDS Volume 20, Number 3, 1989 DISTRIBUTION AND SEASONAL MOVEMENTS OF BENDIRE'S THRASHER IN CALIFORNIA A. SIDNEY ENGLAND, Departmentof Wildlifeand FisheriesBiology, University of California, Davis. California 95616 WILLIAM E LAUDENSLAYER,JR., U.S. D. A. ForestService, Forestry Sciences Laboratory,2081 E. SierraAvenue, Fresno, California 93710 The ecology and distribution of Bendire's Thrasher (Toxostorna bendirei)have been little studiedand are poorlyunderstood. Garrett and Dunn (1981:280) classifiedthe speciesas a "fairlycommon but very local summer resident on the Mojave Desert" in southern California. Californiabreeding populations are known primarily from the eastern Mojave Desert and scattered locations in and around Joshua Tree NationalMonument in the southernMojave Desert (Johnson et al. 1948, Miller and Stebbins1964, Garrett and Dunn 1981), areas frequently visitedby bird watchersand naturalists. However, recordsfrom other parts of the Mojave and Colorado deserts suggest that breeding populationsof Bendire'sThrasher may be more widely distributedthan currentlyrecognized. Also, the preferredbreeding habitat in Californiais relativelywidespread. This habitatis typicallydescribed as Mojavedesert scrubwith either JoshuaTrees (Yucca brevifolia), SpanishBayonet (Y. baccata), Mojave Yucca (Y. schidigera), cholla cactus (Opuntia acanthocarpa,O. echinocarpa,or O. rarnosissirna),or other succulents (Grinnelland Miller 1944, Bent 1948, Garrett and Dunn 1981). Remsen(1978) consideredthe total Californiabreeding population of Bendire'sThrasher to be under 200 pairs, and the specieshas been placedon the list of Bird Speciesof SpecialConcern by the California Departmentof Fishand Game (Remsen1978). It was placedon this list becausepopulations are smalland locallydistributed and believedto be threatenedby off-roadvehicle use, overgrazing,and harvestingof Joshua Treesand other speciesof yucca. In this paper, we report the resultsof a 2-year studyof the breeding- season distributionand movement patterns of Bendire's Thrasher in California. -
The New Water Czars by Daniel Kraker
The New Water Czars by Daniel Kraker A historic water deal could give an impoverished Indian community a path back to its roots — and turn it into one of the West’s next big power brokers Thirty miles south of downtown Phoenix, past the rugged South Mountains rising out of the city’s southern edge, past the acres of asphalt and the 10- lane highways, the city stops abruptly at the bone-dry bed of the Gila River. On the other side of the riverbed, where you might expect to find desert saguaro and cholla, emerald green farm fields blur into the horizon: perfectly flat rectangles laid out one after the other, separated by canals and irrigation Pima Indian Francis Jones irrigates cotton at ditches into a gigantic crossword puzzle-like grid.

Petition to List the Western Joshua Tree Under the California Endangered Species
BEFORE THE CALIFORNIA FISH AND GAME COMMISSION A Petition to List the Western Joshua Tree (Yucca brevifolia) as Threatened under the California Endangered Species Act (CESA) Center for Biological Diversity October 15, 2019 i Notice of Petition For action pursuant to Section 670.1, Title 14, California Code of Regulations (CCR) and Division 3, Chapter 1.5, Article 2 of the California Fish and Game Code (Sections 2070 et seq.) relating to listing and delisting endangered and threatened species of plants and animals. I. SPECIES BEING PETITIONED: Species Name: Western Joshua tree (Yucca brevifolia) as either a full species, or as the subspecies Yucca brevifolia brevifolia. II. RECOMMENDED ACTION: Listing as Threatened The Center for Biological Diversity submits this petition to list the western Joshua tree (Yucca brevifolia) as Threatened pursuant to the California Endangered Species Act (California Fish and Game Code §§ 2050 et seq., “CESA”). The western Joshua tree (Yucca brevifolia), long recognized as a subspecies or variety (Yucca brevifolia brevifolia), has recently been recognized as a full species distinct from its close relative, the eastern Joshua tree (Yucca jaegeriana). This petition demonstrates that the western Joshua tree is eligible for and warrants listing under CESA based on the factors specified in the statute and implementing regulations. Specifically, the western Joshua tree meets the definition of a “threatened species” since it is “a native species or subspecies of a … plant that, although not presently threatened with extinction, is likely to become an endangered species in the foreseeable future in the absence of the special protection and management efforts . .” Cal. -

Velas, Audubon California This report was supported with funding from the National Fish and Wildlife Foundation, the Morgan Family Foundation, and other private donors. © Copyright 2008 The American Ornithologists’ Union and Audubon California INTRODUCTION The California Condor (Gymnogyps californianus) has long been symbolic of avian conservation in the United States. Its large size, inquisitiveness and association with remote places make it highly charismatic, and its decline to the brink of extinction has aroused a continuing public interest in its plight. By 1982 only 22 condors remained, and the last wild bird was trapped and brought into captivity in 1987, rendering the species extinct in the wild (Snyder and Snyder 2000). At that time, some questioned whether viable populations could ever exist again in the natural environment, and whether limited conservation funds should be expended on what they viewed as a hopeless cause (Pitelka 1981). -
