      False easting: 600000.000000
      False northing: 0.000000

      Planar coordinates are encoded using coordinate pair.
      Abscissae (x-coordinates) are specified to the nearest 0.000000.
      Ordinates (y-coordinates) are specified to the nearest 0.000000.
      Planar coordinates are specified in meters.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

    CF 
    Constructed feature: Buildings, structures, roads
    DX 
    Dwarf shrubland: Land on which the shrubs dominate the vegetation and their cover is greater than 10%. Shrubs are generally less than 20 inches (.5 meters) in height. Trees, if present, have a canopy cover of less than 10%
    FL 
    Forestland: Land in which the tree layer is represented by individuals generally over 16 feet (5 meters) tall that are woody perennials and usually single-stemmed. The trees form a canopy cover of 10% or greater. (NOTE: When stands classified as FL are harvested, they will NOT be recoded to another land cover code such as DX or SX even though the vegetation height is altered. We can identify these stands through other fields.)
    FX 
    Forbland: Land on which 50% or greater of the vegetation canopy cover is composed of broad-leaved herbaceous plants other than grass or grass-like plants.
    GX 
    Grassland: Land on which 50% or greater of the vegetation canopy cover is composed of species of the Gramineae, Cyperaceae or Juncaceae families (grasses, sedges and reeds).
    NX 
    Barrenland: Land on which disturbance frequency, ground surface characteristics, or potential site capability inhibits the establishment of a closed canopy forest. Examples are lava flows, mud flows, glacial outwash, periodically inundated flood plains, landform failures such as slumps, avalanches, talus slopes, rock, cinders.
    QX 
    Aquatic: Land on which grasses, grass-like plants or forbs are structurally supported by water year-round or seasonally and may be either rooted or not rooted in substrate. Land in which the herbaceous lifeform layer qualifies as aquatic but which supports either a tree or shrub layer having a canopy cover of 10% or greater will be classified under treeland, shrubland or dwarf shrubland.
    SN 
    Snowfield/glacier. Land covered by permanent snowfield or glacier.
    SX 
    Shrubland: Land on which the shrubs dominate the vegetation and their cover is greater than 10%. Shrubs are 20 inches to 16 feet (.5 to 5 meters) tall and have a non-arborescent form. Trees, if present, have a canopy cover of less than 10%.
    WX 
    Open water: Land which is covered by water year-round and which may support free-floating vegetation (full support by water and not rooted in substrate), if vegetation is present at all. Permanently flooded lands lying below the deep-water boundary of wetlands, where water is the medium within which the dominant organisms live, i.e. deep-water habitats. Examples: Ponds, lakes, rivers, streams, estuaries, reservoirs below draw-down area.
    YX 
    Herbland: Land on which grasses, grass-like plants or forbs dominate the vegetation. The shrub and/or tree layer, if present, is less than 10% canopy cover for each lifeform layer. Includes meadows (wet and dry), bogs, fens, etc.

    LAND_USE
    Land use. Land use classification divides the land surface into categories based on the way the land is used (green tree retention, special habitats, buildings, etc.). This is a multiple entry field.

    PLANT_ASSC
    Plant association. The potential natural plant community, defined as discrete, recurring collections of plant species which maintain stable populations over a long period of time. In some cases, only a general classification of plant association is known for a polygon. These polygons are coded with a 2-character code and general description. Codes beginning with "A" will be migrated to "land use." Codes ending in C0 (zero) were sometimes coded as CO in the database. This error will be corrected, but queries for that information need to include CO and C0.

    Date: 20000714 (change 1 of 8) 
    The VEG table exists in both Oracle and INFO databases. It was originally developed from queries of the district VEGIS database (oracle) and then transferred to INFO and attached to the VEG layer in GIS. Most attention was given to populating the following fields: yr_origin, size_class, land_use, land_cover, and activity. No attempt was made to ensure that all other fields were populated. This forestwide coverage was compiled from district data July, 2000. Forestwide coverages are compiled from district information as needed, on average every 6 months. The currency of data for individual polygons varies across the forest depending on district update and edit cycles.  This cover was built at a map scale of 1:24000.

    Date: 09/21/2007 (change 4 of 8) 
    It was discovered that the OWNERSHIP field was not populated for a variety of stands across the forest, including most of the MR district.  This is because OWNERSHIP is derived from the VEGIS database, and it's not populated for those stands in the database.   To fix this, as a short term solution, on the gis dataset, I selected all veg stands where ownership was null (did not incude stand = 9008000, or stands outside proclaimed wil boundary). Points were created from polygon centroids. Points were overlayed with ADMN polys to capture the owner value for each point.  Points were then joined to VegetationStand and the owner value transferred to OWNERSHIP.
