Name: A.1237
Reference: EcoArt 2002
Description: This alliance is described from partially stabilized dunes and sandhills in southeastern Idaho. Stands occur in areas of actively moving dune deposits, from a few to more than 100 m to windward from the rear of active dunes. Elevations range from 1525-1800 m. Soils are sand, from a few centimeters to over 4 m deep, left behind as the dunes advance. Despite very low moisture levels during the dry season, some moisture is always available to plants. Generally these deposits are less than 40 years old. Stands have a sparse herbaceous layer (17-25% cover) dominated by the strongly rhizomatous perennial grass ~Leymus flavescens (= Elymus flavescens)$ and the perennial forb ~Psoralidium lanceolatum (= Psoralea lanceolata)$. Diversity and cover are low. Other species may include ~Machaeranthera canescens (= Aster canescens), Oxytheca dendroidea (= Eriogonum dendroideum), Eriogonum deflexum$, and ~Achnatherum hymenoides (= Oryzopsis hymenoides)$.
