A Plenipotentiary Conference to Conclude and International Convention on Trade in Certain Species of Wildlife was held in Washington, D.C., February 12 through March 2, 1973. Its purpose was to prepare and adopt a convention on export, import, and transit of certain species of wild fauna and flora. Representatives and observers from 90 countries met in fulfillment of the recommendation stated in Resolution 99.3 of the U.N. Conference on the Human Environment, Stockholm, June, 1972. Included in this pamphlet are several items related to the conference: remarks made by Secretary of the Interior, Rogers C. B. Morton, on February 12; a message from President Nixon read by Secretary Morton that day; statements made on February 12 and March 2 by Russell E. Train, Chairman, Council on Environmental Quality, and head of the U.S. delegation; the report of the U.S. delegation; excerpts from the final act of the conference; text of the Convention on International Trade in Endangered Species of Wild Fauna and Flora; and statements from President Nixon and the U.S. Department of State for Senate approval of the Convention. The appendix lists endangered animals--species now threatened with extinction and those which may become so unless trade is subject to strict regulation. (BL)
