CEGL000693 Juniperus deppeana / Bouteloua gracilis Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Alligator Juniper / Blue Grama Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: No Data Available
Diagnostic Characteristics: A juniper woodland wherein Juniperus deppeana is dominant with a scarce (<1% cover) or common (>1% cover) shrubby understory. Quercus grisea is scarce (< 1% cover).
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Two phases are recognized. The typic phase is slightly moister and cooler and tends to support more pinyon and Utah juniper than the mesquite phase. The mesquite phase is warmer and drier and supports a higher percent cover of mesquite (Stuever and Hayden 1997b).

Dynamics: Juniperus deppeana is well-adapted to survive most fires. It is capable of producing prolific sprouts/ suckers even after significant consumption of the above-ground portions of the plants. This allows Juniperus deppeana to quickly regain dominance on most sites. Mortality of this juniper is quite low following many severe fires. Bouteloua gracilis is generally top-killed by fires. The rhizomes are usually unharmed. Bouteloua gracilis is usually unharmed by fire during years with above normal winter and spring precipitation. Its response to fire varies from being harmed to almost unaffected to actually being increased by fire. Season of burning, soil moisture, temperature, plant community composition and fire severity are some of the factors affecting its responses. Recovery time ranges from 1 to 4 years or more depending on conditions.
