Summary

Defines the key words used in the chapter so people know what the words mean. "Alternative courses of action" means all possible alternatives, not just the original goals or the agency’s usual authority. "Commercial activity" means business or trade, like buying and selling and things that help trade, but not museum displays of items. "Conserve/conserving/conservation" means using whatever methods are needed to bring a threatened or endangered species back to health so protections are no longer needed; examples include research, counts, law enforcement, protecting and restoring habitat, breeding, trapping, and moving animals, and in rare cases controlled taking. "Convention" means the Convention on International Trade in Endangered Species of Wild Fauna and Flora, signed March 3, 1973, and its appendices. "Critical habitat" means specific areas the species uses at the time it is listed that have physical or biological features needed to save the species and may need special care, and it can also include places outside the species’ then-range if the Secretary finds those places are essential; normally it does not mean the species’ entire potential range. "Endangered species" means a species in danger of extinction across all or a large part of its range, except insects the Secretary calls pests when protecting them would pose an overwhelming risk to people. "Federal agency" means any U.S. department, agency, or instrumentality. "Fish or wildlife" means any animal (for example mammals, fish, birds, amphibians, reptiles, mollusks, crustaceans, arthropods, or other invertebrates) and includes parts, products, eggs, offspring, or dead bodies or parts. "Foreign commerce" includes transactions between people in foreign countries, between people in different foreign countries, between a U.S. person and a foreign person, or between U.S. persons when the wildlife has moved outside the United States. "Import" means bringing or trying to bring something into any place under U.S. control, even if customs would not call it an import. "Permit or license applicant" means a person whose permit or license request was denied mainly because section 1536(a) was applied to a federal agency action for which they wanted an exemption. "Person" includes individuals, businesses, organizations, government officers and agencies at any level, and any other entity under U.S. jurisdiction. "Plant" means any plant, including seeds, roots, and other parts. "Secretary" usually means the Secretary of the Interior or the Secretary of Commerce as assigned under Reorganization Plan Numbered 4 of 1970; for enforcing import/export rules about land plants it also means the Secretary of Agriculture. "Species" includes subspecies and any distinct population segment of vertebrate animals that interbreeds when mature. "State" means the several States, the District of Columbia, Puerto Rico, American Samoa, the Virgin Islands, Guam, and the Trust Territory of the Pacific Islands. "State agency" means any state government body that manages or conserves fish, plants, or wildlife. "Take" means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to try to do any of those things. "Threatened species" means a species likely to become endangered in the foreseeable future across all or a large part of its range. "United States," when used geographically, includes all States.
