VEGETATION THEME GROUP

Vegetative information collected included current vegetation, historical vegetation, potential natural vegetation, and lifeform. Vegetation information was collected at the broadscale (1kilometer (km)) and for subsample areas at the midscale (1:24,000). Current broadscale vegetation cover and structure types were classified from the Advanced Very High Resolution Radiometer (AVHRR) satellite imagery (1 km) dataset. Historic cover type and structure for the broadscale were compiled from numerous records such as early US Government land surveys descriptions. Potential vegetation types were determined by subdividing the Basin into warm/dry to cool/moist environments and associating the potential vegetation types and groups with them.
