This coastal strand community is found in extreme southeastern Florida, from St. Lucie County south to Dade County. Its composition is transitional between temperate and tropical communities. Stands characteristically contain <i>Serenoa repens, Coccoloba uvifera, Pithecellobium keyense</i>, and <i>Dalbergia ecastaphyllum</i>. Additional characteristic species include <i>Randia aculeata, Chiococca alba, Ernodea littoralis, Sophora tomentosa, Caesalpinia bonduc, Bursera simaruba, Metopium toxiferum, Chrysobalanus icaco, Ardisia escallonoides, Eugenia foetida, Myrsine floridana, Forestiera segregata, Schinus terebinthifolius</i> (exotic), <i>Casuarina equisetifolia</i> (exotic), and <i>Opuntia stricta</i>. In relation to the vegetation of similar environments just to the north of its range, stands lack several temperate taxa and contain more tropical ones. |

This Colorado Plateau mixed shrub assemblage occurs on steep, rocky colluvial slopes and bedrock canyon rims associated with mesas, canyons, benches, ravines, hills, hogbacks, escarpments and valley sides. Slopes are typically moderate and range from level to steep (0-70%), occur between 1238 and 1700 m (4000-5580 feet) elevation, and tend to occur on southerly to westerly aspects (less often east-facing slopes). Soils are shallow and rocky and range from rapidly drained clay loams to sandy loams derived from shales and sandstones. It tends to be slightly more mesic than most other talus type vegetation. Total vegetation cover is sparse, not exceeding 25%. It is characterized by a scattered mixture of shrubs, among which <i>Rhus trilobata var. trilobata</i> and <i>Ephedra torreyana</i> or <i>Ephedra viridis</i> are conspicuous and either dominant or codominant. As many as ten other species of shrubs may also be present, including <i>Amelanchier utahensis, Artemisia bigelovii, Atriplex confertifolia, Brickellia microphylla, Chrysothamnus viscidiflorus, Coleogyne ramosissima, Ericameria nauseosa, Eriogonum corymbosum</i>, and <i>Philadelphus microphyllus</i>. <i>Fraxinus anomala</i> is absent, and if <i>Pinus edulis</i> or <i>Juniperus osteosperma</i> are present, cover is less than 1%. Herbaceous cover is sparse and variable. Biological soil crust formation is rare on these active slopes. |

Lemna spp. Permanently Flooded Herbaceous Vegetation

This aquatic association of floating vegetation is known to occur throughout North America. Lemna spp. are the sole or dominant plants floating on the water surface. Lemna-dominated aquatic vegetation occupies wetlands that are permanently flooded, semipermanently flooded to seasonally flooded. Water chemistry is fresh. The standing water habitat is relatively shallow, generally less than 2-4 m (6.6-13.1 feet) and occurs as ponds, lakes, ditches, stock ponds, and backwater sloughs of river and stream channels. Standing water for much or most of the growing season is characteristic. Depth of the water is of no consequence to floating plants; they occur where the wind pushes them. Potamogeton spp., Sagittaria spp., or Persicaria spp. may also be present in Rocky Mountain ponds. While these later species are rooted submerged species, and technically not part of the strictly floating community, they do intermingle. Ponds in California may also include Spirodela spp., Azolla spp., and Wolffiella spp. Community composition may change hour to hour, yet the environment, only the top few centimeters of water, is homogeneous. Biomass can be abundant under eutrophic conditions. |
