CEGL001126 Rosa woodsii Wet Shrubland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Woods'' Rose Wet Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This shrubland occurs in the foothills and plains of Montana, Idaho, Nevada, and eastern California. Elevations range from 650-2490 m. Stands occur in floodplains and on alluvial terraces along rivers and streams, on hillsides below springs, and in ravines and swales where overland flow from snowmelt and summer thunderstorms provides additional moisture. It can also occur on disturbed sites with little moisture, such as steep south-facing hill slopes. Sites are flat to moderately steep. Floodplain sites are temporarily flooded, well-drained with no perched water table. Soils range from sandy loams to silt loams. Stands typically have a moderately dense short-shrub layer which Rosa woodsii dominates. Some stands have moderate cover of Rosa acicularis, Symphoricarpos occidentalis, or Toxicodendron rydbergii. Other shrubs can include Artemisia tridentata and Ribes aureum. Some stands have an herbaceous layer dominated by the exotic grasses Poa pratensis or Bromus tectorum and the weedy forb Cirsium arvense. Other common herbaceous species include perennial graminoids, such as Elymus glaucus, Leymus cinereus, Carex spp., Juncus arcticus ssp. littoralis, and Muhlenbergia racemosa, and the forbs Achillea millefolium, Ambrosia psilostachya, Artemisia ludoviciana, Fragaria virginiana, Galium boreale, Geum macrophyllum, and Solidago canadensis.

Floristics: Stands typically have a moderately dense short-shrub layer which Rosa woodsii dominates. Some stands have moderate cover of Rosa acicularis, Rubus idaeus, Symphoricarpos occidentalis, Symphoricarpos oreophilus, or Toxicodendron rydbergii. Other shrubs can include Artemisia tridentata and Ribes aureum. Some stands have an herbaceous layer dominated by the exotic grasses Poa pratensis or Bromus tectorum and the weedy forb Cirsium arvense. Other common herbaceous species include perennial graminoids, such as Elymus glaucus, Leymus cinereus, Pseudoroegneria spicata, Carex spp., Juncus arcticus ssp. littoralis (= Juncus balticus), and Muhlenbergia racemosa, and the forbs Achillea millefolium, Ambrosia psilostachya, Artemisia ludoviciana, Fragaria virginiana, Galium boreale, Geum macrophyllum, Selaginella densa, and Solidago canadensis.

Dynamics:  Rosa woodsii appears to thrive on disturbance. One stand in Montana developed on a dry, southwest-facing slope after a hot fire. Other stands occur on floodplains that experience active flooding.
Environmental Description:  This shrubland is found in Montana, Idaho, Nevada, and eastern California at elevations ranging from 650-2490 m. Stands occur in floodplains and on alluvial terraces along rivers and streams, on hillsides below springs, and in ravines and swales where overland flow from snowmelt and summer thunderstorms provides additional moisture. Stands also occur on moderately steep upper slopes with southwest aspects. Sites are flat to moderately steep. Floodplain sites are temporarily flooded; they are also well-drained and do not have a shallow water table. Soils range from sandy loams to silt loams (Hansen et al. 1995). This association is considered marginally riparian (Manning and Padgett 1995) and often occupies sites on the upland fringe of riparian systems.
Geographic Range: This dwarf-shrub association is known from the foothills and plains of Montana, Idaho, Nevada, eastern California, and potentially Saskatchewan.
