Festuca idahoensis - Hieracium cynoglossoides Grassland | NatureServe Biotics 2019

Name: Festuca idahoensis - Hieracium cynoglossoides Grassland Reference: NatureServe Biotics 2019 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 <i>Pseudoroegneria - Poa</i> 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 bunchgrasses <i>Festuca idahoensis</i> and <i>Pseudoroegneria spicata</i>, with a lower layer of <i>Poa secunda</i>. The perennial forb layer is floristically rich and probably abundant, with <i>Hieracium cynoglossoides</i> 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 <i>Hieracium cynoglossoides</i> in a <i>Festuca idahoensis</i>- and <i>Pseudoroegneria spicata</i>-dominated grassland.  Accession Code: urn:lsid:vegbank.org:commConcept:30528-{61724664-DE8C-493C-8F5B-26DCAFCDA7F7} Plot-observations of this Community Concept: 0
