LANDFIRE Vegetation

Landfire Existing Vegetation Height

Uses NLCD classes, and vegetation categories for grass, shrubs, and trees subdivided into several height categories.

  • Tree classes; 0-5 m, 5-10 m, 10-25 m, 25-50 m, and greater than 50 m, 
  • Shrub classes; 0-0.5 m, 0.5-1.0 m, 1.0-3.0 m, greater than 3.0 m,
  • Herbaceous vegetation classes; 0-0.5 m; 0.5-1.0 m, greater than 1 m.

 

Landfire Existing vegetation Type--Open as a DEM, categories displayed Use the VAT Grid display.  The existing vegetation type (EVT) data layer represents the current distribution of the terrestrial ecological systems classification developed by NatureServe for the western Hemisphere.  Categories defined in the metadata.
  • 2004, North American Warm Desert Sparsely Vegetated Systems
  • 2019, Great Basin Pinyon-Juniper Woodland
  • 2079, Great Basin Xeric Mixed Sagebrush Shrubland
  • 2082, Mojave Mid-Elevation Mixed Desert Scrub
  • 2087, Sonora-Mojave Creosotebush-White Bursage Desert Scrub
  • 2155, North American Warm Desert Riparian Systems
Landfire forest canopy height--categories displayed using Modify, Colors from Grid categories.

Only computed for forest, and does not include shrubs.  If you want to use this, you might want to remove the missing data (category 0).  The values are height in decimeters; half dozen categories (midpoints of class canopy heights in dm).

Forest Canopy cover--percentage of the pixel covered by forest cover, in 10 categories (0, 15, 25, 35, 45, 55, 65,75,85).  Also has non-forest data (0), and missing data
