This community is found throughout the upper midwestern region of the United States and adjacent Canada, ranging to the Northeast, where it develops around spring heads and in broader areas of groundwater discharge. The peat layer is typically less than 0.4 m deep. Tree and shrub cover may vary, particularly from overhanging upland trees, but trees and shrubs rooted in the stand are less than 25% cover. Forbs dominate the community. <i>Symplocarpus foetidus</i> and <i>Angelica atropurpurea</i> are the dominant and indicative species in the Midwest; <i>Impatiens capensis</i> is characteristic in the East. Other forbs and ferns present include <i>Caltha palustris, Chelone glabra, Epilobium coloratum, Impatiens capensis (= Impatiens biflora), Pedicularis lanceolata, Pilea pumila, Saxifraga pensylvanica, Solidago patula</i>, and <i>Thelypteris palustris</i>. Graminoid cover is generally low, less than 25%, and may include <i>Carex bromoides, Carex comosa, Carex lacustris, Carex stricta</i>, and <i>Carex trichocarpa</i>. |

This alliance covers mixed loblolly-hardwood forests of primarily blackwater rivers of the eastern Coastal Plain and related small stream floodplains west of the Mississippi River. Stands are dominated by ~Pinus taeda$ with any combination of the nominal ~Quercus$ species (e.g., ~Quercus laurifolia, Quercus nigra, Quercus phellos$). Some stands could originate as ~Pinus taeda$ plantations, with subsequent ingrowth of the hardwoods. These situations confound the status of this alliance as distinct from its deciduous equivalent (A.292). See the description for the I.B.2.N.d ~~Quercus (phellos, nigra, laurifolia)$ Temporarily Flooded Forest Alliance (A.292)$$ which is very similar, but lacks a significant component of ~Pinus taeda$. This alliance perhaps uncomfortably combines natural, ecologically restricted situations (e.g., CEGL007548 of "sandy blackwater streams and on low, sandy terraces and levees in the Atlantic Coastal Plain") as well as more semi-natural or successional situations under less restricted or clearly defined conditions. |

This cattail community type is found throughout the Northern Great Plains of the United States and Canada. Stands occur in shallow (<0.5 m) or deep depressions, stock ponds, and seepy drainages. The vegetation is dominated by relatively pure stands of <i>Typha</i> spp., either <i>Typha latifolia</i> or <i>Typha angustifolia</i> or both. Many associates can occur, including <i>Eleocharis</i> spp. and <i>Sagittaria latifolia</i>. This type may simply be a less diverse variation of ~<i>Typha</i> spp. - <i>Schoenoplectus</i> spp. - Mixed Herbs Great Plains Herbaceous Vegetation (CEGL002228)$$ that arises in disturbed wetland areas. |

This association represents moist interdune flats codominated by some combination of <i>Muhlenbergia filipes (= Muhlenbergia sericea), Spartina patens, Rhynchospora colorata (= Dichromena colorata)</i>, and <i>Eustachys petraea</i>. Additional graminoids may include lesser amounts of <i>Andropogon glomeratus, Eragrostis spectabilis, Juncus megacephalus, Juncus scirpoides, Panicum virgatum</i>, and the exotic <i>Eremochloa ophiuroides</i>. Forbs may include <i>Centella erecta, Gaillardia pulchella, Heterotheca subaxillaris, Phyla nodiflora, Sisyrinchium atlanticum</i>, and <i>Solidago sempervirens</i>. A sparse (0-10%) layer of emergent shrubs, including <i>Baccharis halimifolia, Juniperus virginiana var. silicicola (= Juniperus silicicola), Morella cerifera, Sideroxylon tenax, Smilax auriculata</i>, and <i>Smilax bona-nox</i>, may also be present. In Florida this community occurs in narrow bands or swales alternating with higher ridges. These often fill with standing water after rains. In North Carolina and Georgia, it may occupy broader grassy flats between the outer dunes and the salt marsh on the inland side of barrier islands, as well as narrow dune swales. Succession to woody vegetation is indicated by increasing cover of <i>Morella cerifera (= Myrica cerifera)</i> or <i>Salix caroliniana</i>. |
