Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Spiranthes magnicamporum
Taxonomic Comments: Spiranthes magnicamporum, by definition, is a stable diploid species within the S. cernua complex. The Spiranthes cernua complex is notorious for hybridization and, although ecologically isolated within their sympatric ranges, a hybrid race of S.magnicamporum and the sand prairie ecotype of S. cernua occurs in the Chicago region. (Catling, 1982)

NatureServe Status

Global Status: G3G4
Global Status Last Reviewed: 04Jul2016
Global Status Last Changed: 04Jul2016
Ranking Methodology Used: Ranked by inspection
Rounded Global Status: G3 - Vulnerable
Reasons: Widely distributed in the central United States, and into south eastern Canada, with disjuncts in the southwest and southeast United States. Favors dry grasslands with limestone bedrock near the surface. Locally infrequent in Huron County, Michigan, but individuals are often scattered. There are greater than 100 occurrences across a large range.

NatureServe Global Conservation Status Factors

Range Extent Comments: Eastern Great Plains, Great Lakes and Midwest regions, with disjunct populations in Utah, Colorado, New Mexico and Alabama-Mississippi (Luer 1975). Also into Ontario and Manitoba (Kartesz unpublished data 1995).

Number of Occurrences: 81 to >300
Number of Occurrences Comments: Extant populations of Spiranthes magnicamporum occur in: Alabama (36--3A-ranked, 1C, 1D; 10 counties) Arkansas (1D), Georgia (6), Illinois (43 counties), Iowa (6 records, but listed S3), Kansas (12), Kentucky (13--3A, 7B, 1C, 2D), Louisiana (1), Michigan (approximately 100 occurrences --ranked S3S4-- in 7 counties), Minnesota (25 records in 16 counties), Missouri (2 counties), Ohio (30--1A, 2B, 3C, 7D), South Dakota (10--1A, 1B, 1C, 3D), Wisconsin (14 counties), Ontario (approximately 50). (Ranks listed were assigned to EORs by individual states and all may not align with compiled RANKSPECS.)

Population Size Comments: Occurs as widely scattered individuals. Plant thrives in Huron County, Michigan where limestone bedrock is close to surface. Locally frequent along Saginaw Bay, Michigan; more rare inland in Great Lakes region (Case 1987). Populations can vary in size from year to year. Identification may be confused with S. cernua, creating an underestimation of occurrences for S. magnicamporum.

Overall Threat Impact Comments: Threats include forest succession, soil disturbance or compaction, loss of habitat to agriculture, overgrazing.

Short-term Trend: Relatively Stable (<=10% change)

Intrinsic Vulnerability Comments: Able to colonize mildly disturbed calcareous habitats (Case 1987).
