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). -

Episodic Death Across Species of Desert Shrubs

JOSEPH WRIGHT, AND HENRY F. HOWE 1Department of Evolution, Ecology and Organismal Biology, Ohio State University, 318 West 12th Avenue, Columbus, Ohio 43210-1293 USA 2Smithsonian Tropical Research Institute, Balboa, Republic of Panama 3Biological Sciences (m/c 066), University of Illinois, 845 West Taylor Street, Chicago, Illinois 60607 USA Abstract. Extreme events shape population and community trajectories. We report episodic mortality across common species of thousands of long-lived perennials individually tagged and monitored for 20 years in the Colorado Desert of California following severe regional drought. Demographic records from 1984 to 2004 show 15 years of virtual stasis in populations of adult shrubs and cacti, punctuated by a 55–100% die-off of six of the seven most common perennial species. In this episode, adults that experienced reduced growth in a lesser drought during 1984–1989 failed to survive the drought of 2002. The significance of this event is potentially profound because population dynamics of long-lived plants can be far more strongly affected by deaths of adults, which in deserts potentially live for centuries, than by seedling births or deaths. Differential mortality and rates of recovery during and after extreme climatic events quite likely determine the species composition of plant and associated animal communities for at least decades. The die-off recorded in this closely monitored community provides a unique window into the mechanics of this process of species decline and replacement. -
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. -
Effects of the Spatial Heterogeneity Formed by Ambrosia Dumosa on Individual and Population Growth of the Invasive Annual Grass Schismus Barbatus
EFFECTS OF THE SPATIAL HETEROGENEITY FORMED BY AMBROSIA DUMOSA ON INDIVIDUAL AND POPULATION GROWTH OF THE INVASIVE ANNUAL GRASS SCHISMUS BARBATUS. DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Susana Rodríguez-Buriticá ***** The Ohio State University 2009 Dissertation Committee: Approved by: Professor Maria M. Miriti, Adviser Professor Ralph Boerner Adviser Professor Elizabeth Marschall Evolution, Ecology and Organismal Biology Graduate Program Professor Karen Goodell ABSTRACT Natural ecosystems are exposed to numerous factors that determine their structure and dynamics. Although change is typically inherent in to biological systems, very few factors change a natural ecosystem as drastically as the arrival and successful establishment of non-native species. The impact of the Mediterranean grass (Schismus barbatus) in the southwestern U.S. exemplifies such dynamics. In my dissertation, I empirically and theoretically explore two components of Schismus invasion. First, native shrubs may promote Schismus invasion if Schismus benefits from the favorable growth conditions that shrubs provide. Second, Schismus may threaten ecosystem level properties if Schismus precludes establishement of shrubs. Thus Schismus may compromise the maintenance of Islands of fertility that favor growth of native plant community. To meet these objectives, I explore Schismus performance with respect to the location and size of one of the most abundant native shrubs in the Sonoran and Mojave Deserts, the Bur-sage shrub, Ambrosia dumosa. As a first approximation to the study system, I describe the natural distribution of Schismus with respect to the location of native shrubs (Chapter 1). Then, I examine factors that control Schismus-Ambrosia interaction using a three-year field experiment (Chapter 2), and subsequent ii characterization of soil nutrients changes around Ambrosia shrubs in the context of Schismus invasion (Chapter 3). -

Ecological Site R030XB139CA Shallow Dry Hill 4-6 PZ
Natural Resources Conservation Service Ecological site R030XB139CA Shallow Dry Hill 4-6 P.Z. Accessed: 09/27/2021 General information Provisional. A provisional ecological site description has undergone quality control and quality assurance review. It contains a working state and transition model and enough information to identify the ecological site. Figure 1. Mapped extent Areas shown in blue indicate the maximum mapped extent of this ecological site. Other ecological sites likely occur within the highlighted areas. It is also possible for this ecological site to occur outside of highlighted areas if detailed soil survey has not been completed or recently updated. MLRA notes Major Land Resource Area (MLRA): 030X–Mojave Desert MLRA Description: Major Land Resource Area (MLRA) 30, Mojave Desert, is found in southern California, southern Nevada, the extreme southwest corner of Utah and northwestern Arizona within the Basin and Range Province of the Intermontane Plateaus. The climate of the area is hot and dry with mostly hyperthermic and thermic soil temperature regimes and typic-aridic soil moisture regimes. Mean annual air temperatures are between 59-68 degrees F (15-20 C) with average summer maximum temperatures between 100-115 degrees F (38-46 C) and average winter minimum temperatures between 32-59 degrees F (0-15 C). This MLRA is within the arid climate zone however steep elevational gradients contribute to microclimates where semi-arid [mean annual precipitation is greater than 8 inches (200mm)] and hyper-arid [mean annual precipitation is less than 4 inches (100mm)] islands exist. Elevations range from below sea level to over 12,000 feet (3650 meters) in the higher mountain areas. -
The Relative Importance of Abiotic and Biotic Factors for Seedling Establishment in the Colorado Desert, CA DISSERTATION Present
The Relative Importance of Abiotic and Biotic Factors for Seedling Establishment in the Colorado Desert, CA DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Natasha Nicole Woods Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2015 Dissertation Committee: Maria N. Miriti, Advisor Peter S. Curtis Kristin L. Mercer Copyright by Natasha Nicole Woods 2015 Abstract Drought combined with warmer temperatures has caused extensive mortality in US southwest desert ecosystems. Disproportional mortality among long-lived shrub species can have dire consequences for community regeneration if novel recruitment is dependent on facilitated establishment. However, regeneration niches can be under biotic or abiotic control. My dissertation research examines mechanisms that control juvenile recruitment in the Colorado Desert, CA. Specifically I examine, seed and seedling responses to resources by partitioning those resources that are under direct biotic control based on the production and consumption patterns of standing vegetation, and those that are under abiotic control due to the effects of temperature and precipitation. By examining the relative importance of abiotic and biotic factors that affect plant recruitment, I can anticipate community stability in the face of natural or anthropogenic disturbance and if necessary offer strategies to mitigate species loss by identification of relevant variables to promote recruitment of target species. In chapter 1 I characterize the spatial and temporal distribution of nitrogen for three years at a long-term study site in the Colorado Desert. In chapter 2, I examine the capacity for dominant shrubs to serve as plant facilitators for seed establishment and use a greenhouse experiment to identify the distinct roles of light and nitrogen on seed ii germination.
