Sage.Dwarf-Shrubland.
Location: This map class was restricted to Chinde Mesa and its associated drainages. It occurred on the
steep slopes of the mesa.
Photosignature: This map class commonly occurred on deep, red clay soils. The shrubs appeared as
grayish green, small, regularly spaced specks. Salvia pachyphylla was not easily distinguishable from other
shrubs on the photos. Field data and locality information were used to determine the extent of this map
class in the Chinde Mesa area. This map class also had occasional Juniperus osteosperma and Pinus edulis
trees that appeared as large, globular trees that gradated from higher elevations.
