CEGL002684 Populus fremontii - Salix gooddingii / Salix exigua Riparian Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Fremont Cottonwood - Goodding''s Willow / Narrowleaf Willow Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This community occurs primarily in the Colorado Plateau, along the lowland river valleys of the Gila River Basin of New Mexico, and on Colorado River tributaries in Arizona and Utah. This type is characterized by tall trees of Populus fremontii and Salix gooddingii, with a shrubby understory dominated by Salix exigua. Other trees present include Alnus oblongifolia, Platanus wrightii, or Fraxinus velutina. Other shrubs that may be present include Baccharis salicifolia, Ericameria nauseosa, and Rhus aromatica. The non-native Tamarix ramosissima can be abundant. The herbaceous layer is usually well-developed with a diversity of native obligate wetland graminoids and pioneering forbs. Stands occur at elevations ranging between 1117 and 1525 m (3600-5000 feet). Stream gradients are low to moderate (0.3% on average), and channel substrates tend to be sands and gravels. Typically, it occurs on low- to mid-level sand and gravel bars within active stream channels that are at bankfull discharge stage or just above it and hence flooded from every one to five years. Soils are moist, well-drained Entisols that are either sandy throughout or sandy underlain by a gravelly matrix. They tend to be dry on the surface most of the year but are usually moist within the rooting zone of most species, particularly during spring runoff.

Classification Comments: The northern extent of this association is largely known from National Park Service inventory efforts in the Colorado Plateau. This is a mid-successional community that forms between the early herbaceous/shrub types on low bars following floods and the late-mature forest types of upper terraces, and is maintained by frequent flooding, especially in confined canyons. This type is closely related to both ~Populus fremontii / Baccharis salicifolia Riparian Woodland (CEGL000941)$$ and ~Populus fremontii - Salix gooddingii / Baccharis salicifolia Riparian Forest (CEGL002683)$$ (Muldavin et al. 2000a). All three types, in turn, are probably refinements of the Fremont cottonwood - willow type of Laurenzi et al. (1983) and Brown et al. (1979), and Populus fremontii / Salix gooddingii community type of Reichenbacher (1984) and Szaro (1989) documented for Arizona, and by Campbell and Dick-Peddie (1964) and Dick-Peddie (1993) in New Mexico.
This type is closely related to both the Populus fremontii / Baccharis salicifolia CT and Populus fremontii - Salix gooddingii / Baccharis salicifolia CT. These types, in turn, are probably further refinements of the Fremont cottonwood-willow type of Laurenzi et al. (1983) and Brown et al. (1979b), and the Populus fremontii / Salix gooddingii community type of Reichenbacher (1984) and Szaro (1989) documented for Arizona, and by Campbell and Dick-Peddie (1964) and Dick-Peddie (1993) in New Mexico.

Floristics: This type is characterized by young to middle-aged stands of Populus fremontii and Salix gooddingii, with a shrubby understory dominated by Salix exigua. Stands are moderately open to closed (40-85% cover). Saplings of Alnus oblongifolia, Platanus wrightii, or Fraxinus velutina may be common in the understory. Other shrub species that may be common but not dominant include Baccharis salicifolia, Ericameria nauseosa, and Rhus aromatica. In some stands, Tamarix ramosissima has invaded and is well-represented. The vine Clematis ligusticifolia can be a common species. The herbaceous layer is usually well-developed with a diversity of native obligate wetland graminoids and pioneering forbs. Of the 37 grasses and forbs recorded for the type, 14 are wetland indicators. The most common natives are Juncus torreyi, Paspalum distichum, Muhlenbergia asperifolia, Cicuta douglasii, and Equisetum laevigatum. Common non-native species present include Elaeagnus angustifolia, Tamarix spp., Bromus rubens, Bromus tectorum, Agrostis stolonifera, Echinochloa crus-galli, and Polypogon monspeliensis.

Environmental Description: This community occurs in lowland river valleys at elevations ranging between 1117 and 1525 m (3600-5000 feet). The stream gradients are low to moderate (0.3% on average), and channel substrates tend to be sands and gravels. Typically, it occurs on low- to mid-level sand and gravel bars and streambanks of active channels that are at bankfull discharge or just above and hence flooded from every one to five years. Soils are moist, well-drained Entisols that are either sandy throughout or sandy underlain by a gravelly matrix. They tend to be dry on the surface most of the year but are usually moist within the rooting zone of most species, particularly during spring runoff.
