Name: Poa nervosa - Achnatherum lettermanii Grassland
Reference: NatureServe Biotics 2019
Description: This plant association occurs at elevations between 3230 and 3450 m (10,600-11,300 feet) and on slopes that are generally less than 15%. The landscape relief is most often concave which lends itself to favorable soil moisture conditions despite the southerly aspects preferred by this community. The soils are deep, well-drained loam with gravel and sand present in the subsurface as well. Parent material for this association is sandstone. In this community, <i>Poa nervosa</i> has approximately 15% cover and <i>Achnatherum lettermanii</i> 11% cover. Associated species include <i>Festuca brachyphylla, Phleum alpinum, Poa fendleriana, Trisetum spicatum, Achillea millefolium var. occidentalis, Agoseris glauca, Erigeron peregrinus, Erigeron simplex, Hymenoxys hoopesii, Polygonum bistortoides, Packera crocata</i> and <i>Viola nuttallii</i>. This classification is based on three stands found in the southeastern and south-central portions of the White River Plateau in Colorado. This community has only been documented in Colorado.
