The reference community is the Ponderosa Pine-Pinyon-Juniper/Oak/Bluestem-Muhly Community. It is characterized by a dominance of ponderosa pine. Associated trees include pinyon pine, alligator juniper, oneseed juniper, and Gambel’s oak. Big bluestem, little bluestem, yellow indiangrass, Muhlenbergia species, and needlegrasses are common warm and cool-season grasses. The south facing aspect prevents closed canopy forest from occurring.
The Ponderosa Pine-Juniper/Oak/Bluestem-Muhly Community is a post-fire community in an early to mid successional stage. Most tree and shrub cover is reduced. Wavyleaf oak will be a part of this community since in rapidly resprouts following fires. Shade intolerant warm-season grasses and will dominated the herbaceous layer with scattered forbs.

The Ponderosa Pine-Pinyon-Juniper/Oak/Threeawn Community is characterized by a low cover of grasses and increased woody shrubs and trees such as juniper and pinyon pine. Unpalatable grasses are common. Other grasses composition will fluctuate depending on grazing intensity.
The Ponderosa Pine-Juniper/Oak/Threeawn Community is a post-fire community in an early to mid successional stage. Most tree and shrub cover is reduced with the exception of wavyleaf oak which rapidly resprouts following fires. Depending on fire severity, pinyon pine can be absent due to its fire sensitivity.
