Wetland Plants and Plant Communities of Minnesota and Wisconsin

Key To the Wetland Plant Communities


1A. Mature trees (dbh of 6 inches or more) are present and form closed stands (more than 17 trees per acre; more than a 50 percent canopy cover) on wet, lowland soils (usually floodplains and ancient lake basins).

1B. Mature trees are absent or, if present, form open, sparse stands; other woody plants, if present, are shrubs or saplings and pole-size trees (dbh less than 6 inches) less than 20 feet high and growing on wet, lowland, or poorly-drained soils, or in groundwater seepage areas.

1Buckthorns (Rhamnus spp.) may occur as dominant shrubs or small trees in disturbed shrub-carrs.
