Name: Arctostaphylos uva-ursi / Pseudoroegneria spicata Dwarf-shrubland
Reference: NatureServe Biotics 2019
Description: This is a minor, small-patch to linear type described from the east slope of the Rocky Mountain Front and is also found on very similar environments throughout the montane zone of southern Alberta. It is characteristic of relatively thin-soiled, well- to rapidly drained and exposed sites that are inferred to be moderately to highly wind-impacted (downslope Chinook winds). Sites are predominantly convex ridgelines with gentle to steep southerly exposures. The inventoried elevation range is from 1342 to 1875 m (4400-6150 feet), though based on reconnaissance information, it is known to span an even broader range. <i>Arctostaphylos uva-ursi</i>, with widely variable cover (10% to 75%), is dominant or codominant in the dwarf-shrub layer (height &lt;50 cm); other consistently present shrubs of this layer are <i>Juniperus horizontalis, Juniperus communis, Dasiphora fruticosa ssp. floribunda</i>, and <i>Rosa</i> spp. Extremely browsed specimens of <i>Amelanchier alnifolia</i> are always present. <i>Pseudoroegneria spicata</i> dominates the herb layer, though its cover is also highly variable (averages about 30%). The only other graminoids having a presence in half the stands are <i>Festuca campestris</i> and <i>Festuca idahoensis</i>; their cover generally does not exceed 5%. The forbs with highest constancy include <i>Galium boreale, Achillea millefolium, Hedysarum sulphurescens, Campanula rotundifolia</i>, and <i>Anemone multifida</i>; only rarely do any of the forbs attain as much as 5% cover, and the lifeform itself comprises less than 15% cover.
