This association occurs in a variety of landscapes and hydrologic regimes across the range of the association. It is known from the northern Great Basin of Nevada, into southeastern Oregon, across the Snake River Plain of southern Idaho, and into Montana. Stands occur from low-elevation (1128 m [3700 feet]), wide floodplains in foothill canyons of high order streams, to low order, moderate-gradient (5% or more), perennial and intermittent streams in relatively narrow V-shaped foothill valleys at mid-elevations (1402-2438 m [4600-8000 feet]). Stands are also known from headwater spring and seep-fed channels. The association typically occurs on stable sites, such as low to moderately high stream terraces (sometimes over 1 m above water table) with silty, sandy, or clayey soils derived from alluvium. Typically found as late-seral, dense, and nearly impenetrable thickets, stands of this association are characterized by mature <i>Salix lucida ssp. caudata</i> about 7 to 8 m tall (with 60 to 90% cover), over an understory of 20 to 50% cover of <i>Rosa woodsii</i> (often most dense in canopy gaps). <i>Ribes aureum, Salix lutea</i>, and <i>Prunus virginiana</i> are commonly associated but with lesser cover than the diagnostic shrubs. While herb species diversity can be moderate, the dense shrub cover prevents light from reaching the soil surface resulting in relatively low cover in the herbaceous layer. <i>Galium triflorum, Maianthemum stellatum, Solidago</i> spp., and <i>Urtica dioica</i> are the most frequently associated forbs, while common graminoids include <i>Carex nebrascensis</i> and <i>Poa pratensis</i>, mostly in moister microsites. This association is probably a late-seral association that forms when floodplain terraces supporting other <i>Salix lucida ssp. caudata</i> associations become drier after natural or disturbance-induced stream channel incision. Because <i>Rosa woodsii</i> often occurs on higher and drier terraces, especially where livestock grazing occurs, it can invade the understory of <i>Salix lucida ssp. caudata</i> stands forming this association. |

Limestone Cobble - Gravel Great Lakes Shore Sparse Vegetation

The limestone cobble - gravel Great Lakes shore type is commonly found along the shorelines of the northern Great Lakes in the United States and Canada. Stands occur between bedrock exposures. Cobble lakeshore is interspersed with pavement lakeshore or low cliff. These cobble - gravel lakeshores support a sparse vegetation. Deep accumulations of large cobbles tend to quite dry and are nearly unvegetated, while shallow accumulations of small gravel and cobbles, especially when mixed with a moist sandy substrate, tend to support denser and more diverse plant cover. The most frequently encountered species include <i>Clinopodium arkansanum (= Calamintha arkansana), Campanula rotundifolia, Carex viridula, Juncus balticus, Juncus dudleyi, Populus balsamifera, Argentina anserina (= Potentilla anserina)</i>, and <i>Oligoneuron ohioense (= Solidago ohioensis)</i>. |
