NatureServe Status

Global Status: G4
Global Status Last Reviewed: 12May2005
Global Status Last Changed: 08Feb1994
Rounded Global Status: G4 - Apparently Secure
Reasons: The species' large overall range and the number of known populations suggest that the taxon is not in immediate danger. However, the small size of most populations, their isolated nature, and the presence of conflicting land uses warrant concern for the species' long-term survival throughout its range.
Nation: United States
National Status: N4

U.S. & Canada State/Province Status
United States California (S4), Colorado (S3S4), Idaho (S3), Montana (S3), Oregon (S3), Utah (S1), Washington (S3), Wyoming (S3)

Other Statuses

NatureServe Global Conservation Status Factors

Range Extent Comments: Washington to central California, and scattered throughout the Rocky Mountains in Idaho, Montana, Wyoming, Utah, and Colorado (Camon and Arnett 1991). It is reported to occur in southern British Columbia but apparently no longer occurs there, or was incorrectly reported as having occurred there (Brownell & Catling 1987).

Area of Occupancy: Unknown 4-km2 grid cells
Area of Occupancy Comments: Area of occupancy is unknown.

Number of Occurrences: > 300
Number of Occurrences Comments: Of the 8 states where this species is reported, only one, California, does not actively computer track occurrences. Three states give it a state rank of "S3", four give it an "S2" and one an "S1". There are over 300 occurrences reported from Oregon (ORNHIC 2002). In 1997, 36 precise locations documented in 7 counties in Colorado.

Population Size Comments: As of 1997, the estimated total number of individuals in Colorado was 10,000. Populations in Wyoming tends to contain relatively few individuals (Fertig 2000). Oregon's plant numbers around 4500. No plant numbers are known for California, Idaho, Montana, Utah, and Washington.

Number of Occurrences with Good Viability/Integrity: Many (41-125)
Viability/Integrity Comments: In Oregon, there are 10 occurrences with 100 or 100+ plants noted. Wyoming notes that most populations contain relatively few plants but there is one with 1000 (WYNHP 2002). It is assumed that among the 5 other states, not including Utah, that there will be a total of at least 30 more populations with 100+ plants.

Overall Threat Impact: High
Overall Threat Impact Comments: This species is threatened by timbering, road construction, development, fire suppression, and collecting (Fertig 2000). Surface disturbances and canopy elimination may also negatively affect this species

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Plants in Wyoming are possibly decreasing due to loss of habitat caused by logging. Recent findings may suggest that the species is more widespread in Wyoming than previously considered (Fertig 2000).

Long-term Trend: Decline of 30-50%
Long-term Trend Comments: Plants in Wyoming are possibly decreasing due to loss of habitat caused by logging. Recent findings may suggest that the species is more widespread in Wyoming than previously considered (Fertig 2000).

Environmental Specificity: Moderate. Generalist or community with some key requirements scarce.
Environmental Specificity Comments: In CA, this species is mostly found in serpentine seeps and along streambanks.
It has been hypothesized that a species of fungus associated with deer or elk feces is required for seed germination. Cypripedium fasciculatum occurs in habitats that burn with some regularity (at least historically). The taxon may be able to survive a low intensity underburn, but not high intensity fires in areas where fuel loading is unnaturally high as a result of decades of fire suppression (WANHP 2002).

Ecology & Life History
Help
General Description: Clustered Lady's-slipper is a perennial with densely hairy, solitary stems, which are 5-20 cm tall and arise from a rhizome. There is a single leaf wrapped around the base of the stem and one pair of sessile, opposite leaves located near the top of the stem; these leaves are broadly elliptic to oval-shaped and are 4-8 cm broad. The 2-4 flowers are tightly clustered at the top of the stem, and each is subtended by a green, lance-shaped bract. The 3 narrowly lance-shaped sepals are 12-25 mm long and greenish brown to purplish with purple lines or spots; the lower 2 are united nearly to the tip. The 2 upper petals are similar to the sepals in shape and color; the lower petal is pouch-shaped, shorter than the sepals, and greenish yellow with brownish-purple margins and often a purple tinge. The ovary and mature capsule are densely hairy.
Technical Description: Plants perennial, stem 0.5-2 dm tall, lanate-pilose, usually with a single sheathing bract near ground level, a pair of opposite leaves at to well above midlength, and often 1 or 2 lanceolate bracts near the inflorescence; obtuse to slightly acute; flowers (1) 2-4 in a rather tight cluster, subtended by conspicuous greenish bracts as long as the densely pilose ovary; sepals lanceolate-acuminate, 12-25mm long, greenish-brown or greenish-purple and usually purple-lined or -mottled, the lower pair fused completely or free at the tips only; petals similar to the sepals but usually somewhat broader; lip depressed ovoid, shorter than the sepals, greenish-yellow with brownish-purple margins and often with purplish tinge; staminodium 2.5-3 mm long, about equalling the longest lobe of the stigma (Hitchcock et. al 1969).
Diagnostic Characteristics: Cypripedium fasciculatum is a distinctive orchid which is easily identifiable in flower and fruit. Its leaves appear to be opposite but they are actually subopposite, joined to the stem almost but not exactly in the same spot about midway up the stem. Species in the genus LISTERA resemble this orchid but are much smaller, have prominent hairs, and flowers arranged in an elongate inflorescence.
Duration: PERENNIAL
Terrestrial Habitat(s): Forest - Conifer, Forest/Woodland
Habitat Comments: C. fasciculatum is found on ultrabasic soils, granitics, schists, limestone and quartz-diorite. Populations have been reported from rocky to loamy soils in damp to dry sites. They are found in mixed evergreen, mixed conifer, and Douglas-fir forests and in pine and black oak stands. Populations are generally found in areas of from 60 -100% shade provided by tree canopy or shrubs (Rice 1984).
