    View State Conservation Rank Criteria
    Population Size

    Score0-1 - Moderate to Large: Population size is imprecisely known but is believed to be >10,000 individuals.

    Range Extent

    Score0 - Widespread species within Montana (occurs in 5% or more of the state or generally occurring in 6 or more sub-basins.) as well as outside of Montana.

    Area of Occupancy

    Score0 - High: Occurs in >25 Subwatersheds (6th Code HUC’s).

    Environmental Specificity

    Score0 - Low: Species is a generalist that occurs in a variety of habitats and/or is tolerant of disturbed or degraded habitats (C -Values of 1-4).

    Trends

    Score0-1 - Stable to Minor Declines:

    Threats

    Score0-1 - Low to Medium.

    Intrinsic Vulnerability

    Score0 - Low Vulnerability: Species does not have any unusual or specific life history or biological attributes or limted reproductive potential which makes it susceptible to extirpation from stochastic events or other adverse impacts to its habitat and thus slow to recover.

    Raw Conservation Status Score

    Score 0 to 3 total points scored out of a possible 19.

 
General Description
Perennial. Stems 20–40 cm long, the area below the stem node smooth and without small bumps, stem bases hard, scaly, and bulb-like. Leaves: blades mostly 2–3 mm wide, ligule about 1 mm long. Inflorescence a narrow panicle 5–12 cm long. Spikelets 2.5–3.5 mm long. Lemmas slightly hairy often towards the base only, awnless or awn-tipped, callus hairs very short or lacking (Lavin in Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).

Range Comments
Throughout the eastern flanks of the Rocky Mountains from NM to AL and east through southcentral Canada and sporadically to the very eastern U.S (Lavin in Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
