Description
Flooding is the major factor of succession along the riparian system. After an extreme or catastrophic flood, the first dominant species to re-establish are the alder and bluejoint. In areas where aggradation has occurred, the plant community may be dominated by paper birch and devils club. With time and little disturbance, white spruce will begin to re-establish.

Description
Within the Mixed Forest/Meadow Flood Plains ecological site, there are areas characterized by hummocks. These hummocky soils support willows (Salix spp.) and bluejoint grass (Calamagrostis canadensis) predominantly. Barclay's willow (Salix barclayi) is the primary willow noted on this site, but otehr willows and woody species do occur in the community. Grasses and forbs provide major cover in the understory. Low spaces between hummocks are commonly dominated by bryophytes (Drepanocladus and Calliergon). Black spruce (Picea mariana) and cottonwood (Populus balsamifera) are scattered across the ecological site but are not a component in this community.
