The Bureau was informed that no new information was received with regard to the two natural World Heritage sites of the United States of America, namely the Everglades and Yellowstone National Parks, and that up-to-date information on the state of conservation of those two sites, based on reports requested from the State Party by 15 September 1998, and expected to be received by then, will be submitted to the twenty-second session of the Committee to be convened in Kyoto, Japan, during 30 November – 5 December, 1998.
