Juniperus ashei Ozark Clifftop Woodland

This association includes <i>Juniperus ashei</i> woodlands occurring on rimrock bluffs and cliffs composed of dolomite (or possibly limestone) in the Ozark Highlands of the United States. These woodlands generally have a pure <i>Juniperus ashei</i> canopy with little other associated vascular flora. Lichens may be abundant on rocks and covering the ground. These woodlands are less diverse than the mixed <i>Juniperus ashei</i> woodlands that occur as glade complexes on less extreme sites in the Ozarks. |

Grasslands of the sod-forming alien species <i>Imperata cylindrica</i>. This community is usually essentially monospecific, dominated by a dense turf of <i>Imperata cylindrica</i>. Many areas occupied by this community are abandoned agricultural lands or other disturbed areas, but others include barrier island dunes. Scattered trees (particularly of successional species) may occur. |

This is a very broadly distributed association occurring in the major ranges of northern Utah, Wyoming, Idaho, eastern Washington and Montana into at least west-central Alberta. In drier climates it is a small-patch type, but with higher precipitation regimes; it can expand to large patches in valley locations. Elevations range from 1250 m in the north to 3355 m at the highest in the south. In the southern portion of this type's distribution, parent materials are largely alluvium, soils are loamy to silty in texture, derived from the local country rock, which ranges from sandstone to basalt to granitics in the vicinity of major batholiths. In the north, sedimentary and metasediments are the rule with silty clay loams and loams predominating. Mottling and rust pockets are found in many soil pits, indicating high water tables or subirrigation for a portion of the year. Subirrigation is reflected by landscape positions on lower terraces and stringers of lower order streams, toeslopes and side-hill seeps. Most of the indicator forbs present are associated with the decidedly rich end of the soil-nutrient regime. The canopy for the most part is open, the modal cover ranging between 40-60%, dominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i>. <i>Pinus contorta</i> is the major seral species in the middle Rockies, whereas in the northern Rockies <i>Pseudotsuga menziesii, Larix occidentalis, Pinus monticola</i>, and <i>Abies grandis</i> are additional seral species. The dominant aspect of the undergrowth is an abundance of medium to tall forbs, though shrub cover can at times approach 50%; shrubs are a more important component in the northern distribution of the association. Shrubs with the highest constancy and cover include <i>Ribes lacustre, Vaccinium membranaceum, Alnus viridis ssp. sinuata, Lonicera utahensis, Cornus sericea</i>, and <i>Menziesia ferruginea</i>. The graminoid component is negligible. Of the forbs diagnostic for the association four, <i>Streptopus amplexifolius, Senecio triangularis, Heracleum maximum</i> and <i>Mitella pentandra</i>, are distributed across the breadth of the type, though there are numerous ancillary high-constancy forbs spanning the type's range including <i>Thalictrum occidentale, Geranium richardsonii, Osmorhiza berteroi, Maianthemum stellatum, Orthilia secunda</i>, and <i>Arnica cordifolia</i> (or <i>Arnica latifolia</i> at higher elevations). <i>Aconitum columbianum, Saxifraga odontoloma (= Saxifraga arguta), Mertensia ciliata</i>, and <i>Mertensia arizonica</i> are wet-site taxa occurring with relatively high constancy in the southerly portion of the association. The forb component of diagnostic species is more diverse from central Idaho northward. |

This pond pine woodland occurs on the Atlantic Coastal Plain of North Carolina and Virginia. <i>Pinus serotina</i> is dominant or codominant with <i>Acer rubrum</i> in the canopy stratum. <i>Acer rubrum</i> and <i>Magnolia virginiana</i> are typically the most important subcanopy trees. Shrub densities are variable, from more than 80% cover to less than 50%. While not always dominant, <i>Ilex glabra</i> is a common and characteristic shrub in this type. Other common shrubs include <i>Lyonia lucida, Clethra alnifolia, Smilax laurifolia, Leucothoe racemosa, Gaylussacia frondosa (= var. frondosa), Vaccinium formosum, Persea palustris, Morella cerifera (= Myrica cerifera var. cerifera)</i>, and <i>Lyonia ligustrina var. foliosiflora</i>. Herbaceous diversity is very low, but <i>Woodwardia virginica</i> and <i>Osmunda cinnamomea</i> can be locally common. Other herbaceous plants include <i>Woodwardia areolata, Osmunda regalis var. spectabilis</i>, and <i>Listera australis</i>. Mosses, including <i>Sphagnum</i> spp., are often abundant in the saturated hummock-and-hollow microtopography. This community is variable in physiognomy, depending on fire frequency. Originally, most occurrences would have manifested themselves at most times as woodlands, with an open canopy structure. Many occurrences currently have denser canopy, up to and including a closed canopy structure. This type is closely related to the ~<i>Pinus serotina / Cyrilla racemiflora - Lyonia lucida - Ilex glabra</i> Woodland (CEGL003670)$$, which occurs farther south and has additional species, particularly <i>Cyrilla racemiflora</i>. |
