Name: Purshia tridentata / Prunus virginiana Shrubland
Reference: NatureServe Biotics 2019
Description: This plant association is described from data collected in St. Anthony Dunes area, Fremont County, Idaho, within the Snake River Basalts ecoregional section. The plant association occurs in areas of stabilized sands, in a region of actively moving dune deposits. At these sites, stable sand deposits are estimated to be 1000 to 4500 years old. Soils are deep, fine- to medium-grained sands. Despite very low moisture levels during the dry season, soil moisture available to plants is apparently adequate, perhaps due to the low soil moisture tension of sand. <i>Purshia tridentata</i> and <i>Prunus virginiana</i> dominate the overstory of these deciduous shrubland stands. <i>Purshia tridentata</i> is typically abundant while <i>Prunus virginiana</i> is often common to well represented. <i>Ericameria nauseosa</i> and <i>Chrysothamnus viscidiflorus</i> may also be present. Associated grass species include <i>Hesperostipa comata, Elymus lanceolatus</i>, and <i>Leymus flavescens</i>. Important forbs are <i>Opuntia polyacantha, Balsamorhiza sagittata</i>, and <i>Psoralidium lanceolatum</i>.
