Name: Populus fremontii - Salix gooddingii / Baccharis salicifolia Riparian Forest
Reference: NatureServe Biotics 2019
Description: This is a lowland forested riparian association known from the Gila River watershed in New Mexico and potentially occurs elsewhere in southwestern New Mexico and southern Arizona. It occurs in lowland river valleys at elevations ranging from 1220 to 1410 m (4000-4625 feet). Stream gradients are moderate (0.3-0.9%), and channel substrates gravelly or finer. Occurring on low- to mid-elevation bars within and along channels, flood-recurrence intervals vary widely, but typically range between two and five years. Some site are considerably higher in the floodplain and are rarely flooded (25-100 years). Soils are young, weakly developed Entisols that are commonly sandy with a cobbly matrix. Others, particularly those of higher terraces, are sandy or loamy throughout. The soils are generally dry on the surface most of the year, but they may be periodically moist within the rooting zone (40-150 cm). The vegetation of this association is characterized by young to middle-aged stands of <i>Populus fremontii</i> and <i>Salix gooddingii</i> with moderate to closed canopies (usually greater than 60% cover). <i>Celtis laevigata var. reticulata, Fraxinus velutina, Juglans major, Juniperus monosperma</i>, and <i>Platanus wrightii</i> can occur as subcanopy associates, but are never dominant. <i>Baccharis salicifolia</i> is well-represented to abundant in the shrub layer and is diagnostic. Other shrubs are scattered and may include <i>Amorpha fruticosa, Ericameria nauseosa, Rhus trilobata</i>, and <i>Salix exigua</i>. The herbaceous layer can range from sparse and species-poor to well-represented and species-rich, but variable. A total of 54 grasses and forbs have been recorded for the type, 7 of which were wetland indicators. The most common were <i>Hydrocotyle verticillata, Schoenoplectus pungens, Phyla lanceolata, Juncus arcticus ssp. littoralis</i>, and <i>Muhlenbergia asperifolia</i>.
