Salix lanata (50% cover) dominates the overstory and Equisetum variegatum (90% cover) dominates the understory (Appendix 4). Salix lanata averages 0.9 meters tall, and Equisetum variegatum less than 0.3 meters. Carex membranacea and Equisetum arvense are common herbaceous associates, and Salix alaxensis and Salix glauca also occur in the overstory.
The one site sampled occurred on a recently deposited and frequently flooded portion of a floodplain at low elevations within the boreal forest zone of the park. The Carex aquatilis plant association occurs on wetter sites, and Picea glauca invades the drier sites.
