Artemisia nova / Poa secunda Shrubland | Western Ecology Working Group of...

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, with a disjunct occurrence in western Colorado. 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 to 2745 m (5000-9000 feet). Stands are on shallow, rocky and gravelly calcareous soils that may be of volcanic origin or derived from limestone. Although it is often in mosaic with <i>Artemisia tridentata</i> or <i>Juniperus</i> spp. stands, this association does not support significant cover or reproduction of these species, nor perennial grasses other than <i>Poa secunda</i>. Some (but not all) stands may represent overgrazed stands of ~<i>Artemisia nova / Pseudoroegneria spicata</i> Shrubland (CEGL001424)$$. <i>Artemisia nova / Poa secunda</i> stands are expected to have low amounts of other shrubs, such as <i>Artemisia arbuscula, Artemisia tridentata ssp. vaseyana, Chrysothamnus viscidiflorus, Eriogonum microthecum</i>, and <i>Tetradymia canescens</i>. Other herbs to be expected in these stands include perennial grasses, such as <i>Achnatherum</i> spp., <i>Koeleria macrantha</i>, and <i>Elymus elymoides</i>, and forbs common on shallow soils, such as <i>Balsamorhiza hookeri, Castilleja</i> spp., <i>Eriogonum</i> spp., <i>Petradoria pumila, Phlox</i> spp., and <i>Penstemon</i> spp. Its presence in Colorado may represent another <i>Artemisia nova</i> association that has been degraded by grazing until only <i>Poa secunda</i> and <i>Koeleria macrantha</i> remain.  Accession Code: VB.CC.34321.CEGL001423 Plot-observations of this Community Concept: 0
