Acarospora socialis in the Joshua Tree National Park (California, U.S.A.) Map collection Acarospora socialis. Photo by Jana Kocourková Kerry Knudsen, Kocourková Jana* *Czech University of Life Sciences Prague, Faculty of Environmental Sciences, Department of Ecology, Czech Republic © 2012 Abstract – Results of research on biodiversity and distribution of Acarospora socialis in the Joshua Tree National Park (Mojave Desert, California) confirm previous knowledge that the species is a common species in southern California. It is probably the most common lichen in Joshua Tree. The map of distribution of A. socialis in Joshua Tree is presented. We compiled a detailed list of records based on GPS data. Key words – Acarospora socialis, lichens, distribution, mapping, Joshua Tree, Mojave Desert Authors – Kerry Knudsen1, Kocourková Jana2 1The Herbarium, Department of Botany & Plant Sciences, University of California Riverside, California 92521, U.S.A. – e-mail: [email protected] 2University of Life Sciences Prague, Department of Ecology, Faculty of Environmental Sciences, Kamýcká 129, Praha 6 – Suchdol, CZ – 165 21, Czech Republic – e-mail: [email protected] Acarospora socialis H. Magn. DESCRIPTION. – Knudsen 2007. WORLD DISTRIBUTION. – Western North America. SUBSTRATE. – Non-calcareous rock, rarely soil and wood; on basalt, gneiss, and granite in Joshua Tree. NOTES. – Acarospora socialis is a common species in southern California occurring on the Channel Islands, in the Peninsular Ranges, and in the Transverse Ranges from low to middle elevations. It extends north in to central California and into the Basin and Range, Sonoran and Mojave flora. It is probably the most common lichen in Joshua Tree. Acarospora socialis occurs in the Mojave and Sonoran Deserts.
California Dreaming

California Dreaming Department of Geology and Geological Engineering University of North Dakota Spring Break Field Trip Guidebook 2006 1 Preface and Itinerary This guidebook was prepared by students who accompanied Dexter Perkins on a trip to California in March 2006. It is really a combination of two different trips, together designed to provide a view of a "cross-section of Earth's crust." There are probably too many stops described here for a single trip, but we present them in an order that is feasible if you have two weeks or so of time. day 1 Arrive in San FRancisco, pick up cars, and proceed north to the first stop at the Ring Mtn. Open Space Preserve in Tibuon. Here you will see various lithologies associated with ophiolites. Continue on to camp in one of the parks near Bodega Bay – Doran Beach is especially nice. day 2 Start with a visit to the classic blueschist locality at Ward Cr., near Cazadero. See additional references listed below. Then, in the afternoon, visit the eclogite/blueschist on the beach just north of Jenner. Return to campground for the night. day 3 Drive south 5 hours to a campground near Pinnacles National Monument. The Pinnacles Campground on the east side of the monument is nice but expensive. (Alternatively, rustic camping is free in the Clear Creek Rec. Area near the New Idria serpentinite – approach from the south). Be sure to drive Hwy 1 south of Bodega Bay all the way south, rather than going inland. Stop at Pt. Reyes along the way, if time permits.
Joshua Tree National Park Geologic Resource Evaluation Scoping

JOSHUA TREE NATIONAL PARK GEOLOGIC RESOURCES MANAGEMENT ISSUES SCOPING SUMMARY Sid Covington Geologic Resources Division 12/15/03 Executive Summary In a Geologic Resources Evaluation scoping meeting held at the headquarters of Joshua Tree National Park (JOTR) in Twentynine Palms, California, May 1, 2003, the scoping meeting participants identified the following geologic resources management issues. 1. Desert crusts and desert pavement are being threatened by social trails near climbing sites and by OHV use. 2. Groundwater levels are being impacted by adjacent development, especially south of the park. 3. Groundwater quality is being impacted by urban development from greater Los Angeles. 4. Surface water quality and quantity is threatened by lowering of groundwater levels, invasion by non-native plants species, air pollution, and deposition from Los Angeles. 5. Seismicity is an important issue impacting health and safety, surface water flow from springs, and the siting of park structures. The Joshua Tree area is seismically active. 6. Mineral extraction and abandoned mineral lands (AML) has resulted in metal contamination, health and safety issues concerning open adits and shafts, and concern for bat habitat. 7. Soils are being impacted by the influx of nitrates and contaminants from urban areas and potentially from the proposed Eagle Mountain landfill. 8. Paleontological resources have not been adequately inventoried and are being threatened by loss, mainly from erosion. Introduction The National Park Service held a Geologic Resources Evaluation scoping meeting at the headquarters of Joshua Tree National Park (JOTR) on Thursday, May 1, 2003. The purpose of the meeting was to discuss the status of geologic mapping in the park, the associated bibliography, and the geologic issues in the park.

Abstract: After adjusting for synonyms and misdeterminations, 279 species in 89 genera are documented herein for the Mojave Desert. This catalog is based on species lists reported in nine peer reviewed publications and includes a general overview of the Mojave Desert in terms of climate, environmental sensitivity, vegetation, and geology. It also includes brief information about each of the eight general collection areas (two papers cover the same study area), as well as a summary discussion of the Mojave Desert lichen flora.

But that is where he spent three weeks tracing the origins of the world’s only known natural example of a quasicrystal — an exotic type of structure discovered in 1982 in a synthetic material by Dan Shechtman, a materials scientist at the Israel Institute of Technology in Haifa who netted the 2011 Nobel Prize in Chemistry for the finding.

PRAISES FOR THE AUTHOR’S DESERT BOOKS Your books open the doors to show visitors (and employees) how to safely and respectfully journey into the amazing landscapes of Death Valley. Having worked in many other national parks, I have seldom seen other books that so single-handedly establish the culture of the backcountry. Your passion for this place is inspiring. This is a superb book that provides a large amount of exceptionally useful information about Death Valley. The author writes with true passion for his subject clearly borne of extensive, first-hand experience. I have read it from cover to cover, and it is probably the best hiking book I have ever read. You have inspired many hikers, walkers, readers and loafers with your poetry about the desert. Your words travel across each page and form trails to new and exciting adventures. So many people love and appreciate what you have written. A must-have book for any desert rat. This book covers an incredible amount of information and detail that will serve me for years to come and many more visits. I can’t tell you how much Hiking Death Valley has meant to my fam- ily...it was really the impetus to get up numerous washes and into canyons that we otherwise probably wouldn’t have pursued. Your books truly amaze me. Your books sit on my shelf, but not for very long because I keep thumbing through them trying to figure out my next adventure. If you are considering going to one of the areas on which he has writ- ten a guide book, do yourself a huge favor and get any of his books.
