Clustered Lady's-slipper (Cypripedium fasciculatum) Conservation Status Review
Review Date = 05/25/2012
Score1-2 - Small to Moderate. Population size is imprecisely known but is believed to be >2,000 individuals and <100,000 individuals.
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.

Score1 - Moderate: Generally occurring in 11-25 Subwatersheds (6th Code HUC’s).
Score0-2 - Stable to Moderate Declines:
CommentTrend data are largely unavailable. Habitat generally appears to be stable and it does not appear likely that severe declines have occurred, though it is possible that minor or moderate declines have occurred or may be occuring across the species' range in Montana.
Score1 - Medium: 11-30% of the populations are being negatively impacted or are likely to be impacted by one or more activities or agents, which are expected to result in decreased populations and/or habitat quality and/or quantity.
CommentLow levels of threats; Timber harvesting has the potential to negatively impact some occurrences and habitat.
Score2 - High Vulnerability: Very specific biological attributes, unusual life history characteristics or limited reproductive potential makes the species highly susceptible to extirpation from stochastic events or other adverse impacts to its habitat and very slow to recover.
CommentSpecies is intrinsicly vulnerable as a result of unusual life history or biological attributes, which makes it vulnerable to localized extirpation.
Score1 - Moderate: Species is restricted to a specific habitat that is more widely distributed or to several restricted habitats and is typically dependent upon relatively unaltered, good-quality habitat (C Values of 5-7).
