2. CLI Level II UTM Digital Data Enhancements

  CLI Level II UTM digital data have undergone the following
  transformation from their original Level I representation:

  a) The existing shoreline, which was previously not well
     defined for this layer, was removed.

  b) The data are now fully integrated with the corresponding
     CLI shoreline layer, i.e. the CLI polygons are no longer
     extended into the water.

  c) The data are projected to UTM.

  d) The CLI class and modifier codes have been combined.

  e) Additional computed variables are included to facilitate
     user interpretation of the data.

  f) A secondary attribute Component Table (CMP.DBF) is
     included and compatible with the ArcView Component Table
     Extension developed by Agriculture Canada.

  Note(s):

     i) The CLI shoreline is based on older edition
        topographic base maps which may no longer be current.

    ii) Strict adherence to the 6-degree UTM zone convention
        has been made during the projection of the data to
        UTM, i.e.:

         Zone 22 - all maps East of 54 W. Longitude
         Zone 21 - all maps between 54 and 60 W. Longitude
         Zone 20 - all maps between 60 and 66 W. Longitude
         Zone 19 - all maps between 66 and 72 W. Longitude
         Zone 18 - all maps between 72 and 78 W. Longitude
         Zone 17 - all maps between 78 and 84 W. Longitude
         Zone 16 - all maps between 84 and 90 W. Longitude
         Zone 15 - all maps between 90 and 96 W. Longitude
         Zone 14 - all maps between 96 and 102 W. Longitude
         Zone 13 - all maps between 102 and 108 W. Longitude
         Zone 12 - all maps between 108 and 114 W. Longitude
         Zone 11 - all maps between 114 and 120 W. Longitude
         Zone 10 - all maps between 120 and 126 W. Longitude
         Zone 09 - all maps West of 126 W. Longitude

        DO NOT ATTEMPT TO PROCESS OR VIEW DATA ACROSS UTM
        ZONES.

   iii) In the process of integrating the CLI shoreline with
        these data, every attempt has been made to conserve
        the look and contents of the printed CLI maps. To
        this end, a restricted small area dissolve procedure
        has been applied to the overlay results. We apologize
        if any of these small areas persists, or if small
        areas have been eliminated as a result of this
        procedure.

    iv) To reduce file sizes and the time for download, a
        mild coordinate reduction has been applied to the
        original lat/lon data before projection to UTM.

8.Narrative Description of CLI Ungulates

  In general, the needs of all ungulates are much alike:
  each individual and species must have a sufficient
  quality and quantity of food, protective cover, and space
  to meet its needs for survival, growth, and reproduction.
  The ability of the land to meet those needs is determined
  by the individual requirements of species or group of
  species under consideration, the physical characteristics
  of the land, and those factors, such as climate,that
  influence the plant and animal communities.

  The degree of limitation associated with each area
  determines its capability class. The subclass denotes the
  primary factor that causes the limitation.

  This classification system is based on two important
  considerations:

    Capability ratings are established on the basis of the
    optimum vegetation stage (successional stage) that can
    be maintained with good wildlife management practices.

    Capability ratings assigned do not reflect present land
    use (except in extreme cases such as heavily populated
    urban areas), ownership, lack or access, distance from
    cities, or amount of hunting pressure.

9.Detailed CLI Ungulates Class Descriptions

    CLASS 1  Lands in this class have no significant
             limitations to the production of ungulates.
             Capability on these lands is high. They provide
             a wide variety and abundance of food plants and
             other habitat elements.

    CLASS 1W Lands in this special class are Class 1 areas
             that are winter ranges on which animals from
             surrounding areas depend.

    CLASS 2  Lands in this class have very slight limitations
             to the production of ungulates.  Capability on
             these lands is high but less than class 1.
             Slight limitations are due to climatic or other
             factors.

    CLASS 2W Lands in this special class are Class 2 areas
             that are winter ranges on which animals from
             surrounding areas depend.

    CLASS 3  Lands in this class have slight limitations to
             the production of ungulates.  Capability on
             these lands is moderately high, but
             productivity may be reduced in some years.
             Slight limitations are due to characteristics
             of the land that affect the quality and
             quantity of habitat, or to climatic factors
             that limit the mobility of ungulates or the
             availability of food and cover.

    CLASS 3W Lands in this special class are class 3 areas
             that are winter ranges on which animals from
             surrounding areas depend.

    CLASS 4  Lands in this class have moderate limitations to
             the production of ungulates.  Capability on
             these lands is moderate.  Limitations are
             similar to those in class 3, but the degree is
             greater.

    CLASS 5  Lands in this class have moderately severe
             limitations to the production of ungulates.
             Capability on these lands is moderately low.
             Limitations are usually a combination of two
             or more of climate, soil moisture, fertility,
             depth of bedrock or other impervious layers,
             topography, flooding, exposure, and adverse
             soil characteristics.

    CLASS 6  Lands in this class have severe limitations to
             the production of ungulates.  Capability on
             these lands is very low.  Limitations are so
             severe that they are easily recognized; for
             example, soil depth may be negligible or
             climatic factors so extreme that ungulate
             populations are severely reduced.

    CLASS 7  Lands in this class have limitations so severe
             that there is no ungulate production.

10.Detailed CLI Ungulates Subclass Descriptions

  With the exception of Class 1, the classes are divided
  into subclasses according to the nature of the
  limitations, which determine the class.  In most cases
  the limitations do not affect the animals themselves, but
  rather the ability of the land to produce suitable food
  and cover plants.  For convenience the subclasses are
  placed in two main groups: those relating to climate and
  those relating to inherent characteristics of the land.

    Climate

    The following are used to denote significant climatic
    factors that may affect either the animals or the ability
    of the land to produce suitable food and cover.

    'A' Aridity - drought or aridity that adversely
        affects the habitat.

    'C' Climate - a combination of climatic factors acting
        to reduce favourable habitat, and the production and
        survival of ungulates.

    'Q' Snow depth - excessive snow depth that reduces the
        mobility of ungulates and availability of food
        plants.

    'U' Exposure or aspect - special climatic factors,
        such as exposure to prevailing winter winds,
        that adversely affect the animals or their
        habitat.

    Land

    The following subclasses are used to denote significant
    characteristics of land that limit its usefulness for
    producing suitable food and cover.  Some may also have a
    slight adverse effect on the animals.

    'F' Fertility - lack of nutrients in the soil for
        optimum plant growth.

    'G' Landform - poor distribution or interspersion of
        landforms necessary for optimum ungulate habitat.

    'I' Inundation - excessive water level fluctuation or
        tidal action that adversely affects the habitat or
        survival of ungulates.

    'M' Soil moisture - poor soil moisture, either
        excessive or deficient.

    'N' Adverse soil characteristics - excessive salinity,
        lack of essential trace elements, or abundance of
        toxic elements in the soil.

    'R' Soil depth - restriction of the rooting zone by
        bedrock or other impervious layers.

    'T' Adverse topography - either steepness or flatness
        of the land.

  Examples

    fertility limitations to deer production as shown:
    5**TF*D

    An area of which 70% is Class 4 for deer with
    limitations due to snow depth and topography and 30% in
    Class 3 wintering area for elk and moose with slight
    limitations due to snow depth: 4*7QT**3W3Q*EM

    An important wintering area for deer and mountain sheep
    of which 60% is class 1 and 40% is class 1 with slight
    limitations due to exposed bedrock as shown:
