    Title: Level III and IV Ecoregions of Oregon
    Edition: 1

Description  
    Abstract
    Ecoregions denote areas of general similarity in ecosystems and in the type,
    quality, and quantity of environmental resources; they are designed to serve
    as a spatial framework for the research, assessment, management, and
    monitoring of ecosystems and ecosystem components. By recognizing the spatial
    differences in the capacities and potentials of ecosystems, ecoregions stratify
    1999). Ecoregions are critical for structuring and implementing ecosystem
    management strategies across federal agencies, state agencies, and
    nongovernment organizations that are responsible for different types of
    resources within the same geographical areas (Omernik and others, 2000).
     
    The approach used to compile this map is based on the premise that ecological
    regions can be identified through the analysis of the spatial patterns and
    the composition of biotic and abiotic phenomena that affect or reflect
    differences in ecosystem quality and integrity (Wiken, 1986; Omernik, 1987,
    1995). These phenomena include geology, physiography, vegetation, climate,
    soils, land use, wildlife, and hydrology. The relative importance of each
    characteristic varies from one ecological region to another regardless of
    the hierarchical level. A Roman numeral hierarchical scheme has been adopted
    for different levels of ecological regions. Level I is the coarsest level,
    dividing North America into 15 ecological regions. Level II divides the
    continent into 52 regions (Commission for Environmental Cooperation Working
    Group, 1997). At level III, the continental United States contains 104
    ecoregions and the conterminous United States has 84 ecoregions (United States
    Environmental Protection Agency [USEPA], 2000). Level IV is a further
    subdivision of level III ecoregions. Explanations of the methods used to
    define the USEPA's ecoregions are given in Omernik (1995), Omernik and others
    (2000), Griffith and others (1994), and Gallant and others (1989).
     
    Oregon contains forested mountains, woodland- shrubland- and forest-covered
    hills, shrub- and grass-covered plains, agricultural valleys, glaciated peaks,
    volcanic plateaus, coastal headlands, marine terraces, beaches, playas and
    wetlands. Ecological diversity is enormous. The west receives plentiful
    precipitation during the fall, winter, and spring. The eastern 2/3 in the
    rain shadow of the Cascade Range and is much drier than the west. There are
    9 level III ecoregions and 65 level IV ecoregions in Oregon and many continue
    into ecologically similar parts of adjacent states (Bryce and others, in press).
     
    This level III and IV ecoregion map was compiled at a scale of 1:250,000. The
    western part was originally published as part of Pater and others (1998). The
    level IV lines in the Columbia Plateau and Blue Mountains were originally
    published in Clarke and Bryce (1997). Ecoregion boundaries in the remainder of
    Oregon depict revisions and subdivisions of earlier level III ecoregions that
    were originally compiled at a smaller scale (USEPA, 1996; Omernik, 1987).
     
    This poster is the product of a collaborative effort primarily between the
    USEPA Region X, the USEPA National Health and Environmental Effects Research
    Laboratory (Corvallis, Oregon), the Oregon Natural Heritage Program, the United
    Department of Agriculture-Natural Resources Conservation Service (NRCS)
    (formerly the Soil Conservation Service), and the United States Department of
    the Interior-Geological Survey (USGS)-Earth Resources Observation Systems
    (EROS) Data Center.
     
    The Oregon ecoregion project is associated with an interagency effort to
    develop a common framework of ecological regions. Reaching that objective
    requires recognition of the differences in the conceptual approaches and
    mapping methodologies applied to develop the most common ecoregion-type
    frameworks, including those developed by the USFS (Bailey and others, 1994),
    the USEPA (Omernik, 1987, 1995), and the NRCS (U.S. Department of Agriculture-
    Soil Conservation Service, 1981). As each of these frameworks is further
    refined, their differences are becoming less discernible. Regional
    collaborative projects such as this one in Oregon, where agreement has been
    reached among multiple resource management agencies, are a step toward
    attaining consensus and consistency in ecoregion frameworks for the entire
    nation.

Supplemental_Information
    Procedures_Used
     
    1)  All ecoregion and subregion delineations are digitized from the
    U.S.G.S. 1:250,000 base maps.  Prior to digitizing each base map must be
    initialized to orient the map and relate it in geographic coordinates to
    the surface of the earth.  When the registration tics are entered at the
    start of digitizing a transformation error of <0.003 must be achieved in
    order to insure a high level of registration accuracy.  The person
    responsible for digital data entry completes a data sheet describing
    coverage name, date of entry, and whether a topology for the coverage is
    established.
     
    2)  After each 1:250,000 base map has been digitized, a topology
    for each coverage is established.  This function creates unique identities
    for each polygon.
     
    3)  Next each base map is tested for polygon errors through an
    internal editing function.  Errors are corrected for unlabeled polygons,
    unclosed polygons, or polygons with more than one label.  Topology is
    reestablished for each coverage and tested again until no error are
    indicated.
     
    4)  The digital coverage is then plotted at the same scale as the
    original base map.  This coverage is overlaid on a light table with the
    original and visually inspected for replication of original lines with
    digitized lines.  Two individuals independently inspect the coverage for
    accuracy.

    Notes
     
    Level IV ecoregion lines were delineated by Sandy Thiele and David Pater
    on the paper 1:250,000 maps using a relatively thick marking pen (Sharpie
    like).  Digitizing was done directly off of paper.  Coast Range was
    digitized by Sue Pierson, Ogden, 1992.  Columbia Plateau was digitized by
    F. Faure, 1994, second revision digitized by S. Azevedo, 1995. Blue Mtns.
    were digitized by S. Azevedo, 1995. Puget lowlands, Willamette Valley,
    Cascades, East Cascade Slope, North Cascades and Klamath Mountains
    ecoregions were digitzed by S. Azevedo, 1995.
