Name:
Populus fremontii Great Basin Riparian Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance contains riparian woodlands dominated by <i>Populus fremontii</i>. Individuals of <i>Populus fremontii</i> are scattered or occur in groves and may reach 30 m in height and 2 m in diameter. Other species that may occur in the canopy/subcanopy include <i>Baccharis salicifolia, Celtis laevigata var. reticulata, Fraxinus berlandieriana, Fraxinus velutina, Juglans microcarpa, Populus deltoides ssp. wislizeni, Prosopis glandulosa, Prosopis pubescens, Prosopis velutina, Salix amygdaloides, Salix exigua, Salix gooddingii</i>, and <i>Salix lasiolepis</i>. The understory of most examples has been considerably altered by grazing and other factors, thus the composition and cover of the native understory are difficult to ascertain, but frequently consists of shrubs and small trees (1-5 m tall). The herbaceous stratum varies in composition and coverage but is characterized by mixed annuals and short-lived perennials. Some areas have high amounts of <i>Tamarix</i> spp. and other exotic invasive trees. This woodland alliance occurs as small isolated stands or as linear bands that parallel stream channels on alluvial fans, in lower canyons in desert mountains, and valleys with dependable subsurface groundwater that varies considerably during the year. In the southwestern U.S., it occurs in western New Mexico, throughout Arizona, lower elevations of Utah, southern and central Nevada and just into the eastern desert of California.
