A3803 Populus fremontii - Fraxinus velutina - Salix gooddingii Riparian Forest & Woodland Alliance

Type Concept Sentence: This alliance consists of riparian woodlands dominated by Populus fremontii or Salix gooddingii often with Fraxinus velutina. It occurs along streams and rivers of the warm Sonoran and Chihuahuan deserts and southern edge of the Colorado Plateau, in Arizona, southeastern California, southern Nevada, southern Utah and southwestern New Mexico and northern Mexico.

Common (Translated Scientific) Name: Fremont Cottonwood - Velvet Ash - Goodding''s Willow Riparian Forest & Woodland Alliance

Colloquial Name: Fremont Cottonwood - Velvet Ash - Goodding''s Willow Riparian Forest & Woodland

Hierarchy Level:  Alliance

Type Concept: This alliance consists of riparian woodlands dominated by Populus fremontii or Salix gooddingii often with Fraxinus velutina, although there are many associations and stands without ash. It occurs along streams and rivers of the southwestern U.S. in Arizona, southeastern California, southern Nevada, southern Utah and southwestern New Mexico and northern Mexico, and is limited to the warm Sonoran and Chihuahuan deserts and southern edge of the Colorado Plateau.

Diagnostic Characteristics: Riparian areas dominated by Populus fremontii, Fraxinus velutina, and/or Salix gooddingii in the Sonoran and Chihuahuan deserts and southern edge of the Colorado Plateau of southern Arizona, southern New Mexico, and northern Mexico.

Physiognomy and Structure: Tall, cold-deciduous trees.

Floristics: Stands are dominated in the overstory canopy with Populus fremontii, Salix gooddingii, and/or Fraxinus velutina. Understory shrubs include Baccharis ssp., Celtis laevigata var. reticulata, Salix spp., Vitis spp., and many others. Herbaceous understory is often dominated by grasses such as Distichlis spicata, Sporobolus airoides and Muhlenbergia rigens.

Dynamics:  Stands are reliant on flooding for reproduction and a shallow water table for maintenance.
Environmental Description:  This alliance occupies riparian areas and seeps, generally with coarse alluvial soils. The water table is generally not more than 1 m below the surface, but changes seasonally.
Geographic Range: This alliance is found in the Sonoran and Chihuahuan deserts and southern edge of the Colorado Plateau of southern Arizona, southeastern California, southern Nevada, southern New Mexico, and northern Mexico.
