This 'tallgrass' community is dominated by <i>Sporobolus silveanus</i>, with lesser amounts of <i>Tridens strictus</i> and <i>Paspalum floridanum</i>. Typically there is a distinct stratum of low-growing species including <i>Dichanthelium linearifolium, Dichanthelium aciculare, Dichanthelium oligosanthes var. oligosanthes, Aira elegans, Eragrostis hirsuta</i>, and <i>Eragrostis capillaris</i>. Areas which have been mowed or overgrazed may have <i>Andropogon ternarius, Rudbeckia maxima, Marshallia caespitosa</i> or scattered woody species such as <i>Maclura pomifera</i> or <i>Juniperus virginiana var. virginiana</i>. This community occurs on loamy, low pH upland soils classified as Alfisols. Low, circular mounds called mima or pimple mounds dot the otherwise flat to gently rolling landscape in the northeastern portion of the Blackland Prairie in eastern Texas. |

Fallugia paradoxa - Rhus trilobata Shrubland

This shrubland association is currently only known from El Malpais National Monument in New Mexico, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association occurs between 2010 and 2325 m (6600-7630 feet) in elevation on gently rolling lava plateaus. Substrates are mainly derived from McCarty's lavaflow, though occasionally from Bandera or Hoya de Cibola flows. Ground cover is dominated by rock with litter or gravel occasionally well-represented. In this shrubland, stunted and depauperate <i>Pinus edulis</i> and <i>Juniperus scopulorum</i> individuals may be scattered, along with occasional <i>Pinus ponderosa</i> and <i>Juniperus monosperma</i>. Shrubs are the main component of the association in frequency and abundance (ranging up to 40% cover). <i>Fallugia paradoxa</i> is the most frequently occurring and abundant shrub (at all sampling sites); <i>Rhus trilobata</i> occurs as frequently but is not as abundant (relative cover about 2%). A strong component of other mesic shrubs such as <i>Forestiera pubescens, Holodiscus dumosus</i>, and <i>Ribes cereum</i> is characteristic of this association. The herbaceous layer is not abundant, with a mean cover of about 6%; forbs usually predominate. <i>Bouteloua gracilis, Bouteloua curtipendula, Elymus elymoides</i>, and <i>Schizachyrium scoparium</i> are the most frequently occurring graminoids, though cover of any individual species is low. Forbs can range as high as 20% total cover, with <i>Heterotheca villosa</i> the most common species found, followed by <i>Artemisia carruthii</i>. |

Schoenoplectus maritimus - Schoenoplectus acutus - (Triglochin maritima) Herbaceous Vegetation

accession code: VB.CC.36758.CEGL002227

Midwestern Ecology Working Group... |

This community type is found in the northeastern Great Plains of the United States and Canada, on sites that are flooded for much of the growing season, including prairie potholes and the margins of streams and lakes. The soils are typically medium to fine-textured and moderately saline to saline. This is an emergent wetland consisting predominantly of medium-tall graminoids. Shrubs are very rare and forbs are not abundant. The canopy of vegetation is often dense, but may be only moderate on more saline sites. <i>Schoenoplectus acutus (= Scirpus acutus)</i> and <i>Schoenoplectus maritimus (= Scirpus maritimus)</i> are typically the most abundant species, either individually or together, in this community. <i>Schoenoplectus maritimus</i> is typically more abundant on stands with higher salinities and may form virtually monotypic stands, while <i>Schoenoplectus acutus</i> tends to dominate on moderately saline sites. Other species commonly found in moderately saline stands include <i>Juncus balticus, Scolochloa festucacea, Schoenoplectus americanus (= Scirpus americanus), Schoenoplectus tabernaemontani (= Scirpus tabernaemontani), Triglochin maritima</i>, and <i>Typha latifolia</i>. <i>Triglochin maritima</i> can also grow on the drier edges of the more saline stands. |
