Cephalanthus occidentalis - Decodon verticillatus Shrub Swamp
Reference:
NatureServe Biotics 2019
Description:
This buttonbush swamp occurs in the northeastern United States. These swamps experience prolonged or semipermanent flooding for much of the growing season, with water tables receding below the soil surface only during drought or very late in the growing season. They occur in a variety of environmental settings, including backwater sloughs or oxbow ponds, wet swales in floodplains, pond and lake borders, and small, isolated depressions where water levels recede very slowly, such as those with perched water tables. The substrate is typically loose muck. <i>Cephalanthus occidentalis</i> is dominant and often monotypic. Occasional associates depend on the environmental setting and most often occur in drier areas. They include <i>Vaccinium corymbosum, Rhododendron viscosum, Acer rubrum, Cornus</i> spp. closer to upland borders, or <i>Acer saccharinum, Fraxinus pennsylvanica</i>, and <i>Viburnum dentatum</i> where adjacent to floodplains, or <i>Decodon verticillatus, Chamaedaphne calyculata</i>, and <i>Spiraea alba var. latifolia</i> in more stagnant basins. Herbaceous species tend to be sparse but can include <i>Glyceria canadensis, Dulichium arundinaceum, Carex stricta, Scirpus cyperinus, Thelypteris palustris, Leersia oryzoides, Acorus calamus, Alisma plantago-aquatica, Polygonum</i> spp., <i>Sparganium</i> spp., and floating or submerged aquatic species such as <i>Lemna minor, Potamogeton natans</i>, and <i>Nuphar variegata</i>. Bryophytes, if present, cling to shrub bases and include <i>Warnstorfia fluitans, Drepanocladus aduncus</i>, or <i>Sphagnum fallax</i>. In disturbed areas, these wetland may be invaded by <i>Lythrum salicaria</i>.
