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

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):11

Use and Trade [top]
