Great Basin Naturalist


Artemisia tridentata/Symphoricarpos oreophilus and Symphoricarpos oreophilus/Artemisia tridentata plant associations were studied in northeastern Nevada. A 60-stand reconnaissance followed by a detailed study of 37 stands differentiated five important habitat types using an association table approach. Data reduction with DECORANA and TWINSPAN also described five plant associations that were differentiated by species occurrence and geographical distribution. All stands were found at elevations between 2,200 and 3,100 m in areas where snow accumulates and is late to melt. Stands are found on 15 families of soils that are relatively deep, often skeletal, dark colored, and productive. The dominant perennial grasses included Agropyron spicatum, Agropyron trachycaulum, and Festuca idahoensis.
