Name: Festuca idahoensis - Hieracium cynoglossoides Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association is found on the 'boundary' between the eastern Cascade foothills and the Columbia Basin of south-central Washington and north-central Oregon. Stands occur at higher elevations than the Pseudoroegneria - Poa Zone in the Columbia Gorge, so it is colder throughout the year, wetter in winter and drier in summer. Soils are loams and silt loams, derived from loess, with a high content of volcanic ash. Fire may play a role in excluding shrub invaders. Little is known floristically about this grassland association except that is dominated by the medium-tall perennial bunch grasses Festuca idahoensis and Pseudoroegneria spicata, with a lower layer of Poa secunda. The perennial forb layer is floristically rich and probably abundant, with Hieracium cynoglossoides well represented and diagnostic. The shrub layer is typically lacking from most stands, and where shrubs do occur there is no one species characteristic of this association. A well-developed cryptogam layer is typical of undisturbed sites. Diagnostic of this grassland association is a floristically rich forb layer dominated by Hieracium cynoglossoides in a Festuca idahoensis- and Pseudoroegneria spicata-dominated grassland.  Accession Code: VB.CC.23694.FESTUCAIDAHOENS Plot-observations of this Community Concept: 0
