Name: Populus deltoides / Ericameria nauseosa Forest
Reference: Western Ecology Working Group of...
Description: This association is found in the San Juan River basin in northwestern New Mexico. The type is found in wide lowland valleys at elevations ranging from 1410 to 1840 m (4625-6025 feet). It usually occurs on high, elevated, dry terraces situated well above the active channel (discharge ratios >5.0), that are rarely flooded (every 25-100 years). Occasionally it occurs on lower alluvial terraces that are more frequently flooded. Soils are dry with no evidence of aquic conditions within 1 m and are either sandy Inceptisols (Fluventic Ustochrepts), reflecting some soil development on the higher terraces, or less undeveloped sandy or sandy and rocky Entisols (Typic Ustifluvent). This type is characterized by open to moderately closed canopies of mature Populus deltoides ssp. monilifera or Populus deltoides ssp. wislizeni, with a shrubby understory dominated by Ericameria nauseosa (= Chrysothamnus nauseosus) and other facultative upland shrub species (one obligate wetland species, Salix exigua, has been recorded for the type). Preliminary data suggest that the herbaceous layer is relatively low in diversity (17 species) and represented by scattered bunch grasses including Sporobolus cryptandrus, Sporobolus airoides, and Aristida purpurea. Seven out of 30 species recorded for the type are exotic.
