Florida's Everglades National Park and a rain forest reserve in Honduras have been removed from the UN's list of world cultural sites in danger after improvements in conservation programs, UNESCO announced on Monday.
The World Heritage Committee commended the United States "for its investment of scientific and financial resources to rehabilitate" the Everglades, which was put on the World Heritage List in 1979 and on the danger list in 1993.
The Everglades, a sanctuary for a large number of birds and reptiles, including threatened species such as the manatee, had been threatened by urban growth and pollution, as well as by the damage caused to Florida Bay in 1992 by Hurricane Andrew.
The committee also welcomed corrective measures taken by Honduran authorities to preserve the Rio Platano Biosphere Reserve, inscribed on the World Heritage List in 1982 and on the Danger List in 1996.
"These corrective measures were destined to relieve the site of encroachment by agriculture, timber trade and hunting," the committee said.
Rio Platano Biosphere Reserve is one of the few remaining tropical rain forests in Central America, home to an abundant and varied plant and wildlife.
Rio Platano also is home to 2,000 indigenous people, whose traditional lifestyles are threatened by encroaching settlements and agricultural development.
Meeting for its 31st session in the southern New Zealand city of Christchurch, the committee is reviewing the state of conservation at the 830 sites on UNESCO's World Heritage List.
