The low numbers and limited distribution of this herbaceous plant contribute to its vulnerability to natural and human-caused disturbances and environmental stresses. Further reduction in the number of plants could affect its reproductive capability and the genetic diversity of the species. Two populations of the Colorado butterfly plant occur on F.E. Warren Air Force Base in Wyoming. In 1990, a research natural area was established to include all the known, naturally-occurring populations on the base. Additionally, various agreements have been implemented to provide protection to the plant on the base and it is the intent of the Service to meet with private landowners and develop further agreements.
Native plants are important for their ecological, economic and aesthetic values.
Plants play an important role in development of crops that resist disease, insects and drought. At least 25 percent of prescription drugs contain ingredients derived from plant compounds, including treatments for cancer, juvenile leukemia, heart disease and malaria, and medicines to assist in organ transplants. Plants are also being used to develop natural pesticides. A species is deemed to be threatened if it is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range. The Endangered Species Act directs Federal agencies to protect and promote the recovery of listed species.
