Name: A.1625
Reference: EcoArt 2002
Description: This alliance occurs in the alpine tundra in the mountains of Colorado. Stands are found in the lower alpine zone between 3300-3410 m elevation on stable scree slopes, usually on southeast-facing slopes in warm, moist microsites. The ground is covered with rock and is snow covered in the winter. In this alliance ~Athyrium americanum$ is the dominant species. ~Ligusticum tenuifolium$ is a constant associate. ~Chamerion angustifolium (= Epilobium angustifolium), Mertensia ciliata, Carex ebenea$, and ~Luzula parviflora$ are often present in the herbaceous layer. Moss cover is very sparse due to the ~Athyrium americanum$ leaf litter that covers the ground surface.
