CEGL005948 Baccharis emoryi / Distichlis spicata Wet Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Emory''s Baccharis / Saltgrass Wet Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This riparian shrubland association is found along the Pecos in southeastern New Mexico. It occurs along low-gradient rivers with sandy-bottomed channels of wide lowland valleys at elevations around 1120 m (3675 feet). Sites are typically riverbars and terraces where flooding varies from common to rare, but the groundwater is usually within 1 m. Soils are reported as weakly developed Aquic Torrifluvents with sandy textures. Baccharis emoryi forms an open-canopied shrub layer with a distinctively grassy herbaceous layer. Distichlis spicata is abundant and dominates the understory with a scattering of other grasses and forbs, including Muhlenbergia asperifolia, Sporobolus airoides, and, occasionally, Schoenoplectus pungens and other hydric indicators. Tamarix ramosissima can be a significant invader and shrub codominant.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is distinguished from others in the alliance by the prevalence of saltgrass meadow species, in particular Distichlis spicata and Muhlenbergia asperifolia. Associations of the ~Baccharis salicifolia Wet Shrubland Alliance (A0933)$$ described elsewhere in New Mexico and the Southwest are closely related. The New Mexico Natural Heritage Program has made Baccharis emoryi / Muhlenbergia asperifolia Shrubland a phase of this type.
