Threats or limiting factors
Threats include coal mining and oil and gas exploration, ORVs, cattle grazing and trampling, damage from wild burros, and highway construction. The most serious threats at this time are coal mining and gas exploration and cattle grazing. Most sites have 2-3 threats per site (USFWS, 2013). Cattle and range improvements effect 90% of known occurrences. Includes: direct physical injury and mortality in individuals, vegetation disturbance, soil removal disturbance, erosion, and disturbance to pollinators (USFWS 2013).
