CEGL005485 Populus fremontii / Tamarix sp. Ruderal Riparian Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Fremont Cottonwood / Tamarisk species Ruderal Riparian Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This ruderal riparian community is likely to be widespread throughout the range of Populus fremontii within the southwestern United States. This deciduous woodland is characterized by a sparse to open canopy of Populus fremontii with an open to very dense tall-shrub layer of Tamarix chinensis. Few other shrubs attain substantial cover due to the competitive nature of Tamarix chinensis, but they may include Forestiera pubescens, Salix exigua, and Ericameria nauseosa. Herbaceous cover is very sparse and may include Artemisia dracunculus, Acroptilon repens, Distichlis spicata, Distichlis spicata, Oxytenia acerosa, and Sporobolus airoides. Stands occur in linear patches on streambanks and terraces, channel beds and river islands at elevations ranging from 1169-1536 m. Slopes are flat to gentle (not exceeding 3% grade), and substrates are composed of new alluvium.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is largely known and described from National Park Service inventory efforts in the Colorado Plateau. Due to low conservation priority and stand density, this community is under-sampled rangewide, but is likely to be widespread within the range of Populus fremontii.

Floristics: This deciduous woodland is characterized by a sparse to open canopy of Populus fremontii with an open to very dense tall-shrub layer of Tamarix chinensis. Few other shrubs attain substantial cover due to the competitive nature of Tamarix spp., but they may include Forestiera pubescens, Salix exigua, Baccharis salicifolia, and Ericameria nauseosa (= Chrysothamnus nauseosus). Herbaceous cover is very sparse and may include Artemisia dracunculus, Acroptilon repens (= Centaurea repens), Distichlis spicata, Distichlis spicata, Oxytenia acerosa, and Sporobolus airoides.

Environmental Description: Stands of this ruderal riparian Populus fremontii woodland are reported from the southwestern U.S. from Green River in the Colorado Plateau, south to middle and lower Colorado rivers (Hunter et al. 1985, Szaro 1989, Von Loh et al. 2002, Lynn et al. 2003). It likely occurs elsewhere in scattered locations along disturbed reaches of rivers and streams within the distribution ranges of Populus fremontii and Tamarix spp. Sites are restricted to streambanks, river islands, terraces and floodplains.
Geographic Range: Stands of this ruderal riparian Populus fremontii woodland are reported from the southwestern U.S. from Green River in the Colorado Plateau, south along the middle and lower Colorado River and tributaries. In the Colorado Plateaus it has been documented from Canyonlands National Park, Glen Canyon National Recreation Area, and Ouray National Wildlife Refuge.
