Carex scirpoidea Alkaline Cliff Sparse Vegetation

This sparsely vegetated cliff association occurs in sub-boreal settings of northern New England, New York, and adjacent Canadian provinces, where weathering of calcium-bearing rock creates calcareous conditions. It is usually found above 305 m (1000 feet) elevation. The vertical cliffs may be composed of alkaline bedrock such as limestone, but this vegetation can also be found on cliffs where the matrix rock is acidic (e.g., schists or even granite), either where local inclusions weather to more nutrient-rich conditions or where fractures conduct more nutrient-rich seepage waters. These cliffs are mostly dry, but may contain small areas of seepy conditions, with associated floristic variation. The patchy vegetation is restricted to cracks and crevices, and can vary from well-vegetated to barren across the cliff face. It is a mixture of scrubby trees and shrubs, herbaceous plants, and bryoids. Characteristic woody plants include <i>Thuja occidentalis, Alnus viridis, Picea rubens, Acer spicatum, Betula papyrifera, Betula alleghaniensis, Ribes triste, Rubus odoratus, Sambucus racemosa (= Sambucus pubens)</i>, and <i>Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda)</i>. Herbs include some assortment of <i>Carex scirpoidea, Carex eburnea, Carex brunnescens, Trichophorum caespitosum (= Scirpus cespitosus), Aralia racemosa, Primula mistassinica, Primula laurentiana, Lobelia kalmii, Arabis lyrata, Saxifraga virginiensis, Saxifraga paniculata (= Saxifraga aizoon), Saxifraga oppositifolia, Saxifraga aizoides, Draba breweri var. cana (= Draba lanceolata), Pinguicula vulgaris</i>, and <i>Rhodiola rosea (= Sedum rosea)</i>. Characteristic ferns include <i>Cryptogramma stelleri, Asplenium trichomanes, Asplenium trichomanes-ramosum, Dryopteris fragrans, Cystopteris bulbifera, Cystopteris fragilis, Gymnocarpium dryopteris, Woodsia ilvensis</i>, and <i>Woodsia glabella</i>. <i>Dryopteris fragrans</i> and <i>Woodsia ilvensis</i> are more constant than the other vascular species. The bryoid flora can be diverse but is little documented outside of New Hampshire. Noted in the New Hampshire study were the calciphiles <i>Distichium capillaceum, Gymnostomum aeruginosum</i>, and <i>Tortella tortuosa</i>, and the circumneutral indicators <i>Amphidium mougeotii</i> (the most frequent of the indicators), <i>Diplophyllum apiculatum, Mnium thomsonii, Myurella sibirica</i>, and <i>Polytrichastrum alpinum (= Pogonatum alpinum)</i>. This association is differentiated from other northeastern cliff associations by the combination of a sub-boreal setting (as evidenced by the woody plants within and surrounding this vegetation: <i>Picea rubens, Alnus viridis, Acer spicatum</i>, etc.) and the presence of calciphiles such as <i>Dryopteris fragrans, Dasiphora fruticosa ssp. floribunda</i>, and <i>Campanula rotundifolia</i>. |

Dulichium arundinaceum Seasonally Flooded Herbaceous Alliance

accession code: VB.CC.18009.DULICHIUMARUNDI
|
Eastern Ecology Working Group of... |

|
This alliance contains basins, swales, moats of bog mats, and pondshores dominated by Dulichium arundinaceum. Communities in this alliance typically occur in basins of porous substrate where the water level drops significantly during dry years. Substrate is variously mucky or sandy. Typical communities also contain a mix of low grasses, sedges, rushes, and scattered shrubs. This alliance is wide-ranging and poorly known. |

This alliance consists of consolidated cliffs or unconsolidated bouldery talus dominated by ~Umbilicaria muehlenbergii$, in combination with other lichens. The only association currently defined in this alliance occurs on talus and exposed outcrops of Tuscarora quartzitic sandstone, at 1050-1400 m (3500-4600 feet) elevation in the central Appalachians, and it is dominated by ~Umbilicaria muehlenbergii, Lasallia papulosa$, and ~Melanelia stygia$. The highly acid, extremely quartzitic rocks support numerous crustose lichens. Crevices with slight soil development have ~Cladina rangiferina$, and very scattered vascular plants, such as ~Vaccinium angustifolium, Menziesia pilosa, Kalmia latifolia$, and ~Sorbus americana$, are established. |

Carex torta - Apocynum cannabinum - Cyperus spp. Herbaceous Vegetation

This herbaceous vegetation occurs on large coarse substrates deposited along medium- to high-energy river channels and, less frequently, exposed lakeshores with heavy wave action. Seasonal flooding and ice-scour maintain the open nature of these communities; generally, they develop in areas of the active channel that are exposed at low water or in drought years. Vegetation can be sparse to dense depending on degree of flooding and length of exposure. Characteristic perennial species that tolerate inundation and flood scouring include <i>Carex torta</i> and low <i>Salix</i> spp. Associated species tend to vary widely from site to site, can be diverse, and may be sparse; they include <i>Apocynum cannabinum, Verbena hastata, Symphyotrichum puniceum (= Aster puniceus), Doellingeria umbellata (= Aster umbellatus), Solidago rugosa, Solidago canadensis, Solidago gigantea, Calamagrostis canadensis, Phalaris arundinacea, Scirpus expansus, Scirpus cyperinus, Thelypteris palustris, Scutellaria lateriflora, Agrostis stolonifera, Dichanthelium clandestinum, Eupatorium maculatum, Eupatorium perfoliatum, Elymus riparius, Cyperus strigosus</i> and other <i>Cyperus</i> spp., <i>Eleocharis</i> spp., <i>Lobelia cardinalis, Onoclea sensibilis, Viola</i> spp., <i>Clematis virginiana, Polygonum amphibium, Polygonum hydropiper, Polygonum pensylvanicum, Polygonum sagittatum, Polygonum persicaria,</i><i> Polygonum punctatum,</i><i> Polygonum lapathifolium, Schizachyrium scoparium, Andropogon gerardii</i>, and occasionally <i>Sanguisorba canadensis</i>. Battered and stunted shrubs and trees can occur, including <i>Salix sericea, Salix eriocephala, Cornus amomum, Betula nigra, Populus deltoides</i>, and <i>Platanus occidentalis</i>. Nonvascular plants can be sparse, but where present can include <i>Bryum</i> spp. Invasive, exotic species can be problematic in these areas, especially <i>Tussilago farfara, Lythrum salicaria, Polygonum cuspidatum, Polygonum persicaria</i>, and in the southern portion of the range <i>Microstegium vimineum</i>. |
