CNVC00078 is a boreal hardwood forest Association that occurs in Alberta, British Columbia (BC) and Yukon. It has a moderately closed canopy dominated by balsam poplar (Populus balsamifera) and/or trembling aspen (P. tremuloides), and a relatively diverse understory. The shrub layer is moderately to well developed and commonly includes prickly rose (Rosa acicularis), red-osier dogwood (Cornus stolonifera) and squashberry (Viburnum edule). A well-developed to dense herb and dwarf shrub layer that is dominated by field horsetail (Equisetum arvense) and/or meadow horsetail (E. pratense) characterizes this Association. Bluejoint reedgrass (Calamagrostis canadensis) is also typical in the Alberta and BC portions of the range. Tall bluebells (Mertensia paniculata) is also a common species. The moss layer is virtually nonexistent; instead the forest floor is typically covered in broad-leaf litter. CNVC00078 occurs on moist, nutrient-rich sites (often floodplains) in a region with a subhumid continental climate. It is an early seral condition that typically establishes after flooding, fire or harvesting.
