CEGL001524 Artemisia nova / Festuca idahoensis Shrub Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Black Sagebrush / Idaho Fescue Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrub herbaceous association has been documented from only two drainages in Idaho, one in the southwest (Owyhee Uplands Section (342C), the other in the Little Lost River valley (Beaverhead Mountains Section, M332E), though it might be more extensive. There is no confirmation of this type occurring in Montana despite extensive searches within M332E. It is associated with limestone or dolomite-like parent materials that weather to shallow, well-drained and highly calcareous soils; information regarding its landscape setting and other abiotic param is lacking. Artemisia nova is the dominant shrub component and Pseudoroegneria spicata is the dominant grass; Festuca idahoensis cover is sufficiently high to indicate a more mesic moisture regime and distinguishes this association from the much more common ~Artemisia nova / Pseudoroegneria spicata Shrubland (CEGL001424)$$.

Environmental Description: It is associated with limestone or dolomite-like parent materials that weather to shallow, well-drained and highly calcareous soils; information regarding its landscape setting and other abiotic param is lacking.
Geographic Range: Its known distribution is from a small portion of the Beaverhead Mountains Section, but within the Idaho portion of this section there is abundant potential habitat. Very similar climate and substrates obtain within Montana and the ranges of all characteristic species extend into southwestern Montana (also part of M332E), but no occurrences of this association have been documented. Its occurrence in southwestern Idaho, as well, places it within a semi-arid climate with less than 11 in. annual precipitation.
