Name: Picea engelmannii / Maianthemum stellatum Forest Reference: Western Ecology Working Group of... Description: This forest association is uncommon on lower slopes and benches in the montane and lower subalpine zones between 1525-2135 m (5000-7000 feet) elevation in the mountains of southwest and central Montana. Soils are gravelly loams to silts derived from calcareous and non-calcareous parent material. This type is characterized by a closed or nearly closed forest canopy. Pseudotsuga menziesii and sometimes Pinus contorta dominate or codominate seral stands. Picea engelmannii or Picea engelmannii X glauca become dominant in late seral stands. There is a moderately dense shrub layer dominated by Juniperus communis, Mahonia repens, Spiraea betulifolia, and Symphoricarpos albus. Calamagrostis rubescens, Carex geyeri, Arnica cordifolia, and Geranium richardsonii dominate the herbaceous layer. Maianthemum stellatum and Thalictrum occidentale are both diagnostic species and may have as little as 1% cover. This association is very similar in composition and abiotic parameters to Picea (engelmannii X glauca, engelmannii) / Galium triflorum Forest (CEGL000409), but this latter association occurs on moist to wet sites and has any two of the following forbs represented: Galium triflorum, Actaea rubra, or Streptopus amplexifolius. This association occurs on more mesic (collecting) positions than other adjacent upland types such as Picea (engelmannii X glauca, engelmannii) / Packera streptanthifolia Forest (CEGL000414), Abies lasiocarpa / Calamagrostis rubescens Forest (CEGL000301) or Pseudotsuga menziesii / Calamagrostis rubescens Forest (CEGL000429).  Accession Code: VB.CC.25298.PICEAENGELMANNI Plot-observations of this Community Concept: 0
