The complete proposed rule to list the Colorado butterfly plant was published in the Federal Register on March 28, 1998. The Endangered Species Act directs Federal agencies to protect and promote the recovery of listed species. Collection of listed plants on Federal lands is unlawful. In addition, proposed Federal projects and actions require review to ensure they will not jeopardize the survival of the species. For private and non-Federal landowners, consultations come into play only in cases where activities affecting listed species require Federal funding or permitting.
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. The U.S. Fish and Wildlife Service is the principal Federal agency responsible for conserving, protecting, and enhancing fish and wildlife and their habitats for the continuing benefit of the American people. It also operates 66 national fish hatcheries and 78 Ecological Services field stations.
