Name: Artemisia nova / Poa secunda Shrubland Reference: Western Ecology Working Group of... Description: This plant association is discontinuously distributed from southeastern Oregon to southeastern and central Idaho. It is purported to occur in California and expected to occur in northern Nevada and Utah. The association has been reported from a wide variety of habitats at elevations ranging from about 1525 m (5000 feet) on the Snake River Plain of eastern Idaho to 2745 m (9000 feet) in the Boulder Mountains of central Idaho. Stands are on shallow, rocky, and gravelly calcareous soils that are often, but not always, of volcanic origin. The plant association has not been formerly described in publications. Although it is often in mosaic with Artemisia tridentata or Juniperus spp. stands, this association does not support significant cover or reproduction of these species, nor perennial grasses other than Poa secunda. Some (but not all) stands may represent overgrazed stands of Artemisia nova / Pseudoroegneria spicata Shrubland (CEGL001424). Based on surveys of Juniperus osteosperma / Artemisia nova / Poa secunda in southern Idaho, adjacent Artemisia nova / Poa secunda stands are expected to have low amounts of other shrubs, such as Artemisia arbuscula, Chrysothamnus viscidiflorus, and Eriogonum microthecum. Other herbs to be expected in these stands include perennial grasses, such as Achnatherum spp. and Elymus elymoides, and forbs common on shallow soils, such as Balsamorhiza hookeri, Castilleja spp., Eriogonum spp., and Penstemon spp.  Accession Code: VB.CC.19054.ARTEMISIANOVAPO Plot-observations of this Community Concept: 0
