VEGETATION: This coniferous swamp is dominated by northern white cedar (Thuja occidentalis) with a groundlayer dominated by cinnamon fern (Osmunda cinnamomea) and marsh fern (Thelypteris palustris). Other species include yellow birch (Betula alleghaniensis), black ash (Fraxinus nigra), speckled alder (Alnus incana ssp. rugosa), poison sumac (Toxicodendron vernix), royal fern (Osmunda regalis), fowl manna grass (Glyceria striata), a sedge (Carex pedunculata), a sedge (Carex gracillima), northern violet (Viola macloskeyi), wild sarsaparilla (Aralia nudicaulis) and jack-in-the-pulpit (Arisaema triphyllum). Several rare orchids occur in this habitat including the Ram's head lady-slipper (Cypripedium arietinum), a species listed as threatened by the State of Minnesota.
SOILS: Lupton muck (Typic Borosaprists), a very poorly-drained soil with an organic layer greater than 51 inches in depth (and can be many feet in depth). Landscape position is an ancient lakebed in the nearly level, sandy outwash of the Anoka Sandplain.
HYDROLOGY: Lupton muck is typically saturated to the surface. During September through May, the seasonal high water table can vary from 12 inches of standing water to a water table 12 inches below the surface.
