  • Watershed Summaries
    Appendix A: Watershed Summaries Preface California’s watersheds supply water for drinking, recreation, industry, and farming and at the same time provide critical habitat for a wide variety of animal species. Conceptually, a watershed is any sloping surface that sheds water, such as a creek, lake, slough or estuary. In southern California, rapid population growth in watersheds has led to increased conflict between human users of natural resources, dramatic loss of native diversity, and a general decline in the health of ecosystems. California ranks second in the country in the number of listed endangered and threatened aquatic species. This Appendix is a “working” database that can be supplemented in the future. It provides a brief overview of information on the major hydrological units of the South Coast, and draws from the following primary sources: • The California Rivers Assessment (CARA) database (http://www.ice.ucdavis.edu/newcara) provides information on large-scale watershed and river basin statistics; • Information on the creeks and watersheds for the ESU of the endangered southern steelhead trout from the National Marine Fisheries Service (http://swr.ucsd.edu/hcd/SoCalDistrib.htm); • Watershed Plans from the Regional Water Quality Control Boards (RWQCB) that provide summaries of existing hydrological units for each subregion of the south coast (http://www.swrcb.ca.gov/rwqcbs/index.html); • General information on the ecology of the rivers and watersheds of the south coast described in California’s Rivers and Streams: Working

  • A CULTURAL RESOURCES INVENTORY and MANAGEMENT PLAN for SONOMA LAND TRUST's Lmle BLACK MOUNTAIN PROPERTY
    A CULTURAL RESOURCES INVENTORY AND MANAGEMENT PLAN FOR SONOMA LAND TRUST'S LmLE BLACK MOUNTAIN PROPERTY By Leslie E. Smirnoff A thesis submitted to Sonoma State University In partial fulfillment of the requirements for the degree of MASTER OF ARTS in Cultural Resources Management IlOffiaSiaco bson, J.D. Tliomas Origer, MA. Copyright 2009 By Leslie E. Smimoff ii AUTHORIZATION FOR REPRODUCTION OF MASTERS THESIS I grant pennission for the reproduction of parts of this thesis without further authorization from me, on the condition that the person or agency requesting reproduction absorb the cost and provide proper acknowledgment of authorship. Date: Street Address City, State, Zip A CULTURAL RESOURCES INVENTORY AND MANAGEMENT PLAN FOR SONOMA LAND TRUSTtS LITTLE BLACK MOUNTAIN PROPERTY Thesis by Leslie E. Smirnoff ABSTRACT PURPOSE OF THESIS: The aims of this thesis are to provide Sonoma Land Trust with a cultural resources management plan that will fit neatly both into any regulatory framework that may become pertinent and with Sonoma Land Trust's mission and future plans for the Little Black Mountain property. Additionally, this document outlines the resources present on the property and discusses potential impacts to them while recommending ways to preserve them. The purpose of a cultural resources inventory and management plan is often in fulfillment of regulatory compliance with the aim of protecting cultural resources. In this case, Sonoma Land Trust is not under any legal mandate to create a plan, but due to a number of known and unexpected cultural resources discoveries on the Little Black Mountain property t the necessity for a management tool that would aid in the preservation of these resources came to light.

  • The Role of Art, Abstract Thincking and Social Relations in the Human Evolution
    Muzeul Olteniei Craiova. Oltenia. Studii şi comunicări. Ştiinţele Naturii. Tom. 32, No. 2/2016 ISSN 1454-6914 THE ROLE OF ART, ABSTRACT THINCKING AND SOCIAL RELATIONS IN THE HUMAN EVOLUTION CORNEANU Mihaela, CORNEANU C. Gabriel Abstract. Before the appearance of Homo sapiens sapiens, some pre-human genotypes that lived on the Earth, left material evidence concerning different events of their social, behavioural or artistic manifestations. One of the earliest proofs is the use of objects from the environment as primitive tools to extract bone marrow, action probably achieved by a population of Australanthropus olteniensis in Romania (Tetoiu, Bugiuleşti, Oltenia, about 2,000,000 BC). Current studies show that pre-human species originated in the African Rift Valley, which provided optimum benefits to its evolution and diversity. Proto-oceanic environmental quality and diet (rich source of polyunsaturated long fibres) ensured brain development and human evolution. Several pre-human species (Homo habilis, H. naledi, H. erectus, etc.) emerged and lived in this area prior to their migration to other continents. Fire making and use, both for cooking and protection against weather and wildlife, was the essential factor for human evolution. Benefiting from the cooked food, pre-human beings had access to richer food resources, which led to the increase of the skeleton, and, implicitly, of the skull and encephalus. This made possible the development of practical utilities, followed by abstract utilities, such as thinking and intelligence. Sexual dimorphism, the presence of the gene FOX-P2 and the development of language, social and tribal life led to the arrangement of the living spaces, family.

  • Phase I Report
    PHASE I REPORT June 2005 Calleguas Creek Watershed Integrated Regional Water Management Plan This Integrated Regional Water Management Plan (IRWMP) is comprised of two volumes: Volume I: Calleguas Creek Watershed Management Plan Phase I Report Volume II: Calleguas Creek Watershed Management Plan Addendum Volume I is provided as a separate document and Volume II is attached. Volume II is intended to bridge the gap between the Calleguas Creek Watershed Management Plan and the requirements for IRWMPs found in the Integrated Regional Water Management (IRWM) Grant Program Guidelines (Guidelines). The two volumes, together, are intended to be a functionally- equivalent IRWMP document. The Guidelines were prepared by the California Department of Water Resources (DWR) and the State Water Resources Control Board (SWRCB) in November 2004 to provide guidance on the process and criteria that DWR and SWRCB will use to evaluate grant applications under the IRWM Grant Program. The Grant program resulted from the passage of Proposition 50, the Water Security, Clean Drinking Water, Coastal and Beach Protection Act of 2002. IRWM is discussed in Chapter 8 of Proposition 50. p:\05\0587108_cmwd_irwmp\attachments\attach3_irwmp\camrosa_only_preface.doc PHASE I REPORT June 2005 Table of Contents Table of Contents........................................................................................................................... i List of Tables...............................................................................................................................

  • Stormwater Management
    3.3 Stormwater Management 3.3 STORMWATER MANAGEMENT This section of the Technical Background Report describes the background, identifies general drainage patterns, existing and future conditions, and related issues in the planning area. The various sources used in the preparation of this chapter include county and local resources such as Ventura County Public Works Agency Watershed Protection District and City of Simi Valley. 3.3.1 Background The City of Simi Valley is located in the southeastern portion of Ventura County immediately adjacent to Los Angeles County. The developed portions of the City are situated primarily on the valley floor with proposed development extending up to the alluvial fans coming out of canyons. The valley is defined by the Santa Susana Mountains on the north and east and by the Simi Hills on the south. The Santa Susana Mountains separate the Simi Valley from the Santa Clara River Valley and Towns Fillmore and Piru to the north. The Simi Hills separate the valley from the City of Thousand Oaks to the southwest, and Moorpark Sphere of Influence separates the western limit.19 The major drainage course through the valley is the Arroyo Simi. The Arroyo Simi is approximately 11.7 miles in length. This major creek drains from the extreme limits of the watershed in the east and northeast, then westerly through the Las Posas Valley (As Arroyo Las Posas) to the Oxnard Plain (as Calleguas Creek) and the Pacific Ocean. Tributaries to Arroyo Simi from the Santa Susana Mountains on the north are (from west to east), Alamos Canyon, Brea Canyon, North Simi Drain, Dry Canyon, Tapo Canyon, Chivo Canyon, and Las Llajas Canyon.
