Field Description
Main ID Information
Title Vegetation Cover for Calumet and Virginia Study Areas
Filename cvegcov.shp, vvegcov.shp ( 'c' is abbreviation for Calumet study area, 'v' is abbreviation for Virginia study area)
Abstract Vegetation cover types for the Calumet and Virginia stockpile study areas were determined by aerial photo interpretation and field checks during fall 2000. Vegetation types were delineated for stockpile areas using 1995 and 1997 color-infrared aerial photographs with a scale of 1:15,840. Major forest vegetation cover types were aspen-birch, conifers and open areas. Size class and density determinations were made on forested covers to distinguish merchantability and open areas.
Place Keywords Stockpile, Mesabi Iron Range, Virginia, Calumet, Minnesota
Theme Keywords vegetation, stockpile
Time Period of Content Vegetation covers determined from air photos dated 1995 and 1997; and from field checks in 2000.
Parent Theme StkpCint and StkpVint, shapefiles of stockpile outlines used as boundary for vegetation data
Spatial Extent of the Data Parts of Itasca County and St. Louis County near the cities of Calumet and Virginia, respectively.

Purpose Vegetation was classified to help estimate potential value of forested stands and to determine where tree cover may impede access to potential stockpile aggregate areas.

vegtyp_map text, 10 Vegetation cover types as seen on the project plates
"ASPEN <5" Aspen-Birch, 1-5 inches dbh - Aspen-Birch is major species component of forest canopy, with over 50% canopy cover and majority of trees over 1 inch, but less than 5 inches diameter at breast height. (I.e., dbh). Generally considered non-merchantable.
"ASPEN >5" Aspen-Birch, over 5 inches dbh - Aspen-Birch is major species component of forest canopy, with over 50% canopy cover and majority of trees over 5 inches dbh. May be merchantable.
"CONIFER <5" Conifers, 1-5 inches dbh - Conifers (pine, spruce, balsam fir) are major species component of forest canopy, with over 50% canopy cover and majority of trees over 1 inch, but less than 5 inches dbh. Generally considered non-merchantable.
"CONIFER >5" Conifers, over 5 inches dbh - Conifers (pine, spruce, balsam fir) are major species component of forest canopy, with over 50% canopy cover and majority of trees over 5 inches dbh. May be merchantable.
"OPEN" Open - barren, open water, grassland, shrub, or tree reproduction area (less than 1 inch dbh); or any forest canopy with less than 50% cover.
