ATTACHMENT SS2 REGION 2 SENSITIVE SPECIES EVALUATION FORM Species: Adoxa moschatellina L. / Muskroot, Moschatel / ADMO Criteria Rank Rationale Literature Citations Currently, there are 26+ populations of Adoxa moschatellina listed in the Black Hills, 1 • Fertig, 2000 1 B in Wyoming and 25 in South Dakota. There are 7 other known locations throughtout Distribution • FS Records within R2 Wyoming. The plant occurs in Colorado, but no information is available about its • Spackman et al., 1997 frequency and abundance. If Adoxa is found to be more frequent in Colorado, then the ranking could possibly be lowered to a C. Confidence in Rank High Widely distributed in the Rocky Mountains, the Northern United States and Canada. In • NatureServe, 2001 2 C regions where it has been ranked, it is usually S3, S2 or S1. The C rank is based on Distribution outside R2 distribution. In terms of abundance, if the plant warrants S3 – S1 rankings over much of its range, then a B ranking is appropriate for this criterion because it may be widespread but uncommon. Confidence in Rank Medium Adoxa moschatellina is a perennial, and possesses short rhizomes, so asexual • Great Plains Flora, 1986 3 B reproduction is possible. No information was found about seed or pollen dispersal. Dispersal • Watson and Dallwitz, 1992 - Capability The rarity of this plant is readily attributed to its very specific habitat requirements onwards. therefore seed and pollen dispersal are limited by habitat factors. • Larson & Johnson, 1999 Confidence in Rank Medium The populations in South Dakota tend to be small but there are moderate numbers of • Fertig, 2000 4 B them. The plant is said to be rare but locally common in the Black Hills. The Abundance in • Larson & Johnson, 1999 R2 populations in Wyoming are similar. No information is available for the populations in Colorado. Confidence in Rank Medium 5 D No information is available about population trends. • Fertig, 2000 Population Trend in R2 Confidence in Rank High In the Black Hills, Adoxa moschatellina occurs at high altitudes in cold air drainages • Fertig, 2000 6 B primarily on granite. The habitat in Wyoming is listed as moist, moss-rich limestone Habitat Trend • Larson & Johnson, 1999 in R2 cliffs and ledges in Engelmann Spruce and Douglas-fir habitat. The rarity of this plant is readily attributed to its very specific habitat requirements. Confidence in Rank Medium USDA-Forest Service R2 Sensitive Species Evaluation Form Page 1 of 4 ATTACHMENT SS2 Species: Adoxa moschatellina L. / Muskroot, Moschatel / ADMO Criteria Rank Rationale Literature Citations The habitat is vulnerable primarily because of the small population sizes at most • Fertig, 2000 7 B localities. Alteration of the habitat may eliminate the plant. Many sites are found in the Habitat Vulnerability Norbeck Wilderness Area therefore they are protected from certain management or activities. Modification Confidence in Rank Medium 8 D Plant is rhizomatous and may withstand some disturbance (what type or how much • Great Plains Flora, 1986 disturbance is unknown).
