Rare in Montana. Currently known from two occurrences in the northwest portion of the state. Trend data are unavailable. The known sites do not appear likely to be negatively impacted or threatened from human activity at the current time.
- Details on Status Ranking and Review
Score3 - Vey Small: Generally <2,000 individuals.
CommentOne population was observed to only have several dozen plants. The other population was only described as locally common. Additional population information should be collected.
Score1 - Peripheral, Disjunct or Sporadic Distribution in MT: Widespread species that is peripheral, disjunct or sporadically distributed within MT such that it occurs in <5% of the state (<7,500 sq. miles or the combined area of Beaverhead and Ravalli Counties) or is restricted to 4-5 sub-basins.
Area of Occupancy
Score3 - Very Low: Generally occurring in 3 or fewer Subwatersheds (6th Code HUC’s).
Score1-2 - Moderate to High.
Score0-3 - Population trends are unknown.
CommentTrend data are unavailable. Habitat is remote and generally not subject to human disturbance but downward trends are possible due to dorought or warming conditions.
Score0 - Low: Impacts, if any, to the species are expected to be minor or insignificant (affecting <10% of populations) in severity, scope and immediacy.
Score1-2 - Moderate to High Vulnerability.

Running-pine is a low evergreen perennial with densely leafy, branched, upright shoots that are 5-8 mm in diameter including the leaves, arising from sparsely leafy, rooted, horizontal stems at the surface. Upright shoots have 2-4 low, ascending vegetative branches and a taller, terminal branch that usually bears a single club-like cone. Appressed to ascending green leaves are crowded on the branches in longitudinal rows of six or more. The leaves are 3-5 mm long by 0.4-0.7 mm wide, with smooth margins and pointed tips ending with hairs. A solitary (rarely 2) terminal cone is borne on an unbranched peduncle , 3.5-12.5 cm long, with sparse appressed leaves. The cone is 20-55 mm long by 3-5 mm long, and is composed of tightly packed sporophylls that are 1.5-2.5 mm long and gradually taper to a a hair tip. Kidney shaped sporangia are borne within at the bases of the sporophylls.
Producing spores in July.
Lycopodium lagopus is most closely related to L. clavatus. Both species have branched upright shoots, hair tipped leaves in rows of 6 or more, and cones on peduncles distinct from leafy branches. The latter differs by having more lateral spreading branches rather than ascending ones, longer, more spreading leaves, and 2-5 cones borne on a loosely branched peduncle. A hand lens may be needed for positive identification.
