This floodplain community is restricted to a very small area of the province. Much of the original extent of this community has been converted to agricultural use and channelled for water management purposes. There are no verified occurrences within protected areas. This community occupies active floodplain sites over fluvial materials, with a high water table for part of the year. Soils are poorly drained Gleysols with a rich nutrient regime.
Sites are somewhat dry to wet and susceptible to cold air drainage.
This community is often adjacent to the Pinus ponderosa - Populus balsamifera ssp. Rhus radicans plant community. SW Structural stages 1-3 Selected references Lea, E.C., R.E. Maxwell, W.L. Harper and L. Bonner. Environ., Lands and Parks, Wildl. B.C. Meidinger, D.V. 1990.
