Name: Leucopoa kingii Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alpine grassland alliance occurs in the central Rocky Mountains of southwestern Montana and adjacent Bitterroot Range in east-central Idaho. Elevations range from 2900-3600 m. Stands are found in parks in the upper subalpine zone and undulating alpine meadows and turf. Sparse stands dominated by Leucopoa kingii (= Festuca kingii) may occur on the rocky transition zones with fell-fields. Sites are dry, with nearly level to steep slopes. Aspect is typically on the warmer, drier southeastern to western slopes, but can include north-facing slopes. Sites generally have only moderate wind exposure. Soils are shallow to moderately deep, gravelly, well-drained and often with rock outcrops. The vegetation is characterized by a moderate to dense herbaceous layer dominated by Leucopoa kingii. Carex elynoides is codominant in some stands. Other characteristic species include Agoseris glauca, Cymopterus nivalis (= Cymopterus bipinnatus), Oxytropis campestris, Phlox pulvinata, Poa fendleriana ssp. fendleriana, Poa secunda, and Pseudoroegneria spicata. Mosses and lichens have low cover. Shrubs and dwarf-shrubs may include scattered Artemisia frigida, Artemisia tridentata, and Chrysothamnus viscidiflorus at lower elevations. Diagnostic of this alliance is the dominance of Leucopoa kingii in the herbaceous layer.  Accession Code: VB.CC.19045.LEUCOPOAKINGIIH Plot-observations of this Community Concept: 0
