Name: Aquilegia micrantha Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association is restricted to perennial seeps in crevices, ledges, and alcoves in sandstone canyon walls in western Colorado. Sites may be on inaccessible cliff faces or moderate to steep ledgy canyon slopes oriented to any aspect. Soils are sandy, poorly drained and often have a white salt crust on the surface. The underlying geology is usually sandstone or a fine conglomerate, and is often extensively exposed throughout stands of this association. Stands are often linear, following horizontal joints in the bedrock from which groundwater emerges. Changes in the seasonality, quantity or chemistry of the groundwater may result in changes in community extent, density and composition. The vegetation consists primarily of forb species, among which <i>Aquilegia micrantha</i> is always present and often patchily dominant. Other forb species that are often present include <i>Cirsium calcareum</i> and <i>Solidago simplex</i>, as well as the lianas <i>Toxicodendron rydbergii</i> and <i>Clematis ligusticifolia</i>. <i>Calamagrostis scopulorum</i> and <i>Mimulus eastwoodiae</i> are absent. Graminoids contribute little cover within the garden but may be more abundant in the plunge pools at the base of the cliff or the apron of eroded debris below the seep. Scattered shrubs and trees are often present, either within the garden or also rooted in the debris apron. Woody species vary from site to site but often include <i>Pinus edulis, Juniperus osteosperma, Fraxinus anomala, Cercocarpus intricatus</i>, and <i>Amelanchier utahensis</i>.  Accession Code: VB.CC.31964.CEGL002762 Plot-observations of this Community Concept: 0
