Bowlin et al. (1992) did research on the reproductive biology of this species. Over 50 species of insects were found foraging on flowers of this species, about half of them native bees, and eighteen of the different species of ants, which were found foraging on pollen in the flowers (Bowlin 1992). Seeds can be produced both by selfing and outcrossing, but only with the aid of insect pollinators (Bowlin 1992).
Large numbers of individuals over a small range and restricted to a very specific habitat. Known from 19 occurrences with threats at almost every location; some occurrences are reported to be extirpated (Reveal 2003).
Threats include habitat conversion to agriculture, residential development, off-road vehicles, gas and oil exploration (USFWS 1988).
Six meta-populations consisting of a total of 20 sites are now known; estimated total population for the species is ca. 45,000-50,000 individuals (USFWS 1988).

Bureau of Land Management, Uncompahgre Basin Resource Management Plan and Record of Decision: July, 1989. This plan completes the designation process for Fairview RNA/ACEC. This plan prohibits surface occupancy of the RNA for oil, gas or mineral extraction, but not grazing or utility facilities. Grazing will continue unless studies determine the plants or potential habitats are being damaged. (BLM 1988, 1989)
