This ecoregion section occupies low elevation rolling slopes and flatlands derived from glacial processes like outwash plains and moraines. Elevations range from 0-1000 meters, with soils formed primarily from glacial sediments. Extensive wetland systems and poorly drained depressions are common, as well as black spruce (Picea mariana) forests. Bottomland spruce forests comprised of white spruce (Picea glauca) and poplar (Populus spp.) are frequent along rivers, as well as thickets of willow (Salix spp.) and alder (Alnus spp.). Permafrost and wildfires are rare.
