Type Concept: This forest association is currently only known from Great Sand Dunes National Park and Preserve in Colorado, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association occurs in streambeds and drainage channels at 2710 to 3150 m elevation. Terrain is flat to gently sloping and southwest-facing. This palustrine type ranges from seasonally flooded to permanently flooded with moderately drained sandy loam soils. Litter and duff dominate the ground cover with a significant portion of wood and rock. This forested association is dominated by Populus tremuloides in the canopy and subcanopy layers with cover ranging from 30-50%. The tall-shrub layer is dominated by Salix drummondiana with 10-20% cover. Other shrub species that may be present include Acer glabrum, Lonicera involucrata, Rosa woodsii, Ribes spp., Rubus idaeus, and Sambucus racemosa. The herbaceous layer is sparse and generally includes both graminoids, such as Calamagrostis canadensis and Carex spp., and forbs, such as Actaea rubra, Artemisia franserioides, Fragaria virginiana, Geranium richardsonii, Heracleum maximum, Oreochrysum parryi, and Thalictrum fendleri.
