Red Maple Seepage Swamp Forest (Southern New England-Northern Piedmont)
Where to Explore It
Red Maple Seepage Swamp grows in shallow basins saturated with water during spring and summer, from southern New England to the Piedmont of Virginia. By mid-spring, it’s impossible to miss the carpet of skunk-cabbage in the shade beneath red maple, ashes, and other trees.

More About This Natural Community
In spring and early summer, the Red Maple Seepage Swamp is carpeted with skunk-cabbage. At other times of year, it can be quite sparse, with widely scattered ferns. This fairly uncommon natural community occurs in swampy areas fed by groundwater. Look for it in saturated situations on slightly sloping hillsides, along small streams, or in depressions. In general, these swamps are not particularly species-rich. The canopy is dominated by red maple, and you’ll often also see green ash and white ash. Other trees might include tuliptree and swamp white oak. In the shrub layer, you may see common winterberry, northern spicebush, and sweet pepperbush (summersweet). In the field layer (low plants) look for skunk-cabbage in spring and summer, and cinnamon fern from spring to fall.
