CEGL000704 Juniperus monosperma / Andropogon hallii Open Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: One-seed Juniper / Sand Bluestem Open Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is described from central and northern New Mexico on valley plains with deep, sandy soils. Juniperus monosperma is the dominant overstory species with canopy cover from 5-30%. Pinus edulis is absent or only occasionally present. Shrubs can be scarce or sometimes well represented but Psorothamnus scoparius is considered a diagnostic species for the association. Andropogon hallii and Muhlenbergia pungens are the diagnostic herbaceous species.
Diagnostic Characteristics: This juniper woodland has a grassy understory which includes Andropogon hallii and/or Muhlenbergia pungens. The shrub Psorothamnus scoparius is also present.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association appears to be very similar to ~Pinus edulis / Andropogon hallii Open Woodland (CEGL000774)$$ in its environmental setting and species composition. The exception is that ~Pinus edulis / Andropogon hallii Open Woodland (CEGL000774)$$ has both Pinus edulis and Juniperus monosperma in the overstory and lacks the shrub Psorothamnus scoparius.
