Wetland Plants and Plant Communities of Minnesota and Wisconsin
V. SHRUB SWAMPS
Shrub swamps are wetland plant communities dominated by woody vegetation less
than 20 feet in height and with a dbh of less than 6 inches. Shrub swamps of
Minnesota and Wisconsin are categorized as shrub-carrs and alder thickets depending
on the dominant shrub species. Both occur on organic soils (peat/muck) as well
as on the alluvial mineral soils of floodplains.
Shrub swamps provide high value habitat for many songbirds, ruffed grouse,
American woodcock and small mammals, and may be particularly important winter
habitat for ring-necked pheasant, eastern cottontail, and white-tailed deer.
