click to update datacart
Name: Pseudotsuga menziesii / Festuca idahoensis Woodland Reference: NatureServe Biotics 2019 Description: This lower montane woodland association occurs in the central and northern Rocky Mountains from western Montana to northeastern Washington and south to western Wyoming. Elevations range from 915 to 2440 m (3000-8000 feet). Stands occur on mid to low slopes and benches on all aspects near lower tree line or on warm and dry sites at higher elevations. Soils are variable and range from silty loam to gravelly sandy loam derived from a variety of calcareous and noncalcareous parent materials. Surface rock usually is less than 10% but may be as high as 30% cover. The typically open tree canopy is dominated by <i>Pseudotsuga menziesii</i> alone or codominated by <i>Pinus ponderosa</i>. The tree canopy varies from savanna to closed and may include scattered <i>Juniperus scopulorum, Pinus contorta</i>, or <i>Pinus flexilis</i> trees. <i>Artemisia tridentata</i> shrubs are often prominent, but seldom have over 10% cover. Scattered <i>Amelanchier alnifolia</i> and <i>Ribes cereum</i> are often present. The dense to moderately dense perennial graminoid layer characteristically dominates the understory. <i>Festuca idahoensis</i> and <i>Pseudoroegneria spicata</i> codominate with <i>Carex geyeri, Carex rossii</i>, or <i>Leucopoa kingii</i> sometimes prominent. There is often a high diversity of forbs, but typically all have low cover except <i>Balsamorhiza sagittata</i>. The most common forbs species are <i>Achillea millefolium, Antennaria microphylla, Arnica cordifolia, Fragaria virginiana</i>, and <i>Geum triflorum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:29809-{F3B5EDB3-118C-42A1-9996-45DCF8969186} Plot-observations of this Community Concept: 4
