  • 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).

    anran Forestry Department Food and Agriculture Organization of the United Nations GLOBAL FOREST RESOURCES ASSESSMENT COUNTRY REPORTS NITED TATES OF MERICA U S A FRA2005/040 Rome, 2005 FRA 2005 – Country Report 040 UNITED STATES OF AMERICA The Forest Resources Assessment Programme Sustainably managed forests have multiple environmental and socio-economic functions important at the global, national and local scales, and play a vital part in sustainable development. Reliable and up- to-date information on the state of forest resources - not only on area and area change, but also on such variables as growing stock, wood and non-wood products, carbon, protected areas, use of forests for recreation and other services, biological diversity and forests’ contribution to national economies - is crucial to support decision-making for policies and programmes in forestry and sustainable development at all levels. FAO, at the request of its member countries, regularly monitors the world’s forests and their management and uses through the Forest Resources Assessment Programme. This country report forms part of the Global Forest Resources Assessment 2005 (FRA 2005), which is the most comprehensive assessment to date. More than 800 people have been involved, including 172 national correspondents and their colleagues, an Advisory Group, international experts, FAO staff, consultants and volunteers. Information has been collated from 229 countries and territories for three points in time: 1990, 2000 and 2005. The reporting framework for FRA 2005 is based on the thematic elements of sustainable forest management acknowledged in intergovernmental forest-related fora and includes more than 40 variables related to the extent, condition, uses and values of forest resources.

Common name toyon, California Christmas berry, California-holly (Painter 2016); Christmas berry (CalFlora 2016). D. Taxonomic relationships Phylogenetic analyses based on molecular and morphological data confirm thatPhotinia is the most closely related genus (Guo et al. 2011). Photinia differs in having 20 stamens, fused carpels, and stone cells in the testa as well as occurring in summer-wet environments (Phipps 1992). E. Related taxa in region None. There is only one species of Heteromeles. The closely related Photinia is primarily tropical (Meyer 2008) and not in California. Toyon's taxonomic stability may be in part related to its reproductive mode (Wells 1969). F. Taxonomic issues The three varieties of H. arbutifolia listed above in cell I. B. are currently recognized in the USDA PLANTS (2016) database. G. Other One of the most widely distributed California shrubs. Also widely planted and well-known for its bright red fruits in winter. McMinn (1939) noted it had been planted widely in parks and gardens since about 1914. From the Greek words 'heter' for different and 'malus' for apple (Munz 1974).
