This species was discovered in 1997, and since then the area where it occurs has undergone continuing transformation for agricultural purposes, which has resulted in an estimated 30% population loss in a short period (six years). Therefore the species is listed as Vulnerable.
Previously published Red List assessments:
2002 Vulnerable (VU)
2002 Vulnerable (VU)

Population [top]

Population: This species is known from two locations, with 21 very fragmented subpopulations each comprising only a very small number of plants (5–20 each). The plants are very scattered on prairies. Since its discovery in 1997, several subpopulations were destroyed by agricultural activity. This decline in extent of occurrence has happened very rapidly.
Current Population Trend: Decreasing
