    DEDICATED TO THE PRESERVATION OF THE CALIFORNIA NATIVE FLORA NEWSLETTER Vol. 2, No. 3 June 1983 There wi 11 be no meetings in July and August. In lieu of field trips during the sumner, scouting trips to check on rare plant distribution will take place. Those who wi sh to become in- volved should contact Vince Yoder, -m 876-4275. President's message: Although we appear to be a little less active during the sumner, we should remember the need for our vigilance must continue unabated. And this can be expressed effectively in letter writing. The extent of the government's retreat from its duties to protect the lands from environmental destruction is appalling. The collective voice of CNPS members can be considerable when letters flood to legislators and officials at all levels of government. - The voiceof the people is still strong, but wemust keep shouting tobe heard. So take up pen and paper and keep the letters flowing, even in the sumne r . ---Vi nce Yoder FIELD TRIP REPORT The field trip of May 28-30 was an enjoyable experience for those who showed up. It was like another world as we had the Eureka Dunes all to ourselves, and only a helicopter broke the silence in the Last Chance Mountains. The small number in the group allowed flexibility for visit- ing rare sites. Among the interesting plants observed were: Astraqalus lentiqinosus var. micans (Eureka milk-vetch) Astragalus panamintensis (Cliff milk-vetch) Buddleia utahensi s (Utah buddleja) Cercocarpus intricatus (Little-leaf mahogany) Chaetadelpha wheeleri (Dune broom) Chamaesyce ocellata, formerly Euphorbia ocellata (Valley spurge) Cleome sparsifolia (Naked cleome) Cymopterus gilmanii (Gilman cymopterus) Dedeckera eurekensis (Dedeckera or July gold) Dicoria canescens ssp.

  • Winter Observations on the Colorado Desert
    MAR., 1902. ( THE CONDOR 37 In some respects the Oregon song sparrow is a remarkable form. It is darker than the races north and south of its range, and duplicates in coloring the sooty song sparrow of the Sitkan District. The races along the coast seem thus to alternate light and dark. But whilephea is nearly identical with ru@a in color, it is conspicuously smaller, and the ranges of the two are separated by several hundred miles. The present form occupies a strip along the coast from the northern limit of the redwoods (?) or at least from Rogue River north to Yaquina. The specimens from Crescent City are probably migrants as the breeding birds seem nearer deonensis (tho not precisely typical). The area ofi intergradation between cdeonen- sis and phcza is probably small, extending perhaps from Crescent City to Chetco R. (northern limit of Sequoia sempervivens). Lack of specimens prevents the exact determination of the limits of$hcPa at the north. I am indebted to Mr. Robert Ridgway and to Dr. C.

  • CDFG Natural Communities List
    Department of Fish and Game Biogeographic Data Branch The Vegetation Classification and Mapping Program List of California Terrestrial Natural Communities Recognized by The California Natural Diversity Database September 2003 Edition Introduction: This document supersedes all other lists of terrestrial natural communities developed by the Natural Diversity Database (CNDDB). It is based on the classification put forth in “A Manual of California Vegetation” (Sawyer and Keeler-Wolf 1995 and upcoming new edition). However, it is structured to be compatible with previous CNDDB lists (e.g., Holland 1986). For those familiar with the Holland numerical coding system you will see a general similarity in the upper levels of the hierarchy. You will also see a greater detail at the lower levels of the hierarchy. The numbering system has been modified to incorporate this richer detail. Decimal points have been added to separate major groupings and two additional digits have been added to encompass the finest hierarchal detail. One of the objectives of the Manual of California Vegetation (MCV) was to apply a uniform hierarchical structure to the State’s vegetation types. Quantifiable classification rules were established to define the major floristic groups, called alliances and associations in the National Vegetation Classification (Grossman et al. 1998). In this document, the alliance level is denoted in the center triplet of the coding system and the associations in the right hand pair of numbers to the left of the final decimal. The numbers of the alliance in the center triplet attempt to denote relationships in floristic similarity. For example, the Chamise-Eastwood Manzanita alliance (37.106.00) is more closely related to the Chamise- Cupleaf Ceanothus alliance (37.105.00) than it is to the Chaparral Whitethorn alliance (37.205.00).

  • Habitat Selection of the Desert Night Lizard (Xantusia Vigilis) on Mojave Yucca (Yucca Schidigera) in the Mojave Desert, California
    Habitat selection of the desert night lizard (Xantusia vigilis) on Mojave yucca (Yucca schidigera) in the Mojave Desert, California Kirsten Boylan1, Robert Degen2, Carly Sanchez3, Krista Schmidt4, Chantal Sengsourinho5 University of California, San Diego1, University of California, Merced2, University of California, Santa Cruz3, University of California, Davis4 , University of California, San Diego5 ABSTRACT The Mojave Desert is a massive natural ecosystem that acts as a biodiversity hotspot for hundreds of different species. However, there has been little research into many of the organisms that comprise these ecosystems, one being the desert night lizard (Xantusia vigilis). Our study examined the relationship between the common X. vigilis and the Mojave yucca (Yucca schidigera). We investigated whether X. vigilis exhibits habitat preference for fallen Y. schidigera log microhabitats and what factors make certain log microhabitats more suitable for X. vigilis inhabitation. We found that X. vigilis preferred Y. schidigera logs that were larger in circumference and showed no preference for dead or live clonal stands of Y. schidigera. When invertebrates were present, X. vigilis was approximately 50% more likely to also be present. These results suggest that X. vigilis have preferences for different types of Y. schidigera logs and logs where invertebrates are present. These findings are important as they help in understanding one of the Mojave Desert’s most abundant reptile species and the ecosystems of the Mojave Desert as a whole. INTRODUCTION such as the Mojave Desert in California.

  • Birds of the California Desert
    BIRDS OF THE CALIFORNIA DESERT A. Sidney England and William F. Laudenslayer, Jr. i INTRODUCTION i \ 1 The term, "California desert", as used herein, refers to a politically defined region, most of i which is included in the California Desert Conservation Area (CDCA) designated by the Federal Land ; and Management Act of 1976 (FLPMA). Of the 25 million acres in the CDCA, about one-half are i public lands, most of which are managed by the Bureau of Land Management (BLM) according to the "980 P California Desert Conservation Area Plan mandated by FLPMA. The California desert encompasses those portions of the Great Basin Desert (east of the White and lnyo Mountains and A south of the California-Nevada border), the Mojave Desert, and the Colorado Desert which occur " within California; it does not include areas of riparian, aquatic, urban, and agricultural habitats . adjacent to the Colorado River. (Also see chapters on Geology by Norris and Bioclimatology by E3irdsI4 are the most conspicuous vertebrates found in the California deserts. Records exist for at least 425 species (Garrett and Dunn 1981) from 18 orders and 55 families. These counts far exceed those for mammals, reptiles, amphibians and fish, and they are similar to totals for the entire state -- 542 species from 20 orders and 65 families (Laudenslayer and Grenfell 1983). These figures may seem surprisingly similar considering the harsh, arid climates often believed characteristic of I desert environments. However, habiiats found in the California desert range from open water and h marshes at the Salton Sea to pinyon-juniper woodland and limber pinelbristlecone pine forests on a few mountain ranges.

Related taxa in region Adenostoma sparsifolium Torrey, known as ribbon-wood or red-shanks is the only other species of Adenostoma in California. It is a much taller, erect to spreading shrub of chaparral vegetation, often 2–6 m tall and has a more restricted distribution than A. fasciculatum. It occurs from San Luis Obispo Co. south into Baja California. Red-shanks produces longer, linear leaves on slender long shoots rather than having leaves clustered on short shoots (lacks "fascicled" leaves). Its bark is cinnamon-colored and in papery layers that sheds in long ribbons. F. Taxonomic issues The Jepson eFlora and the FNA recognize A. f. var. prostratum but the taxon is not recognized by USDA PLANTS (2016).

  • 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.
