Current conservation issues
At its last session (Merida, 1996), the Committee noted significant progress made with regard to acquisition of land, refinement of ecological indicators, and generous Federal and State allocations of financial and human resources, but decided to retain this site in the List of World Heritage in Danger due to continued prevalence of threats. In response to the Committee's call to the State Party to share knowledge and experience gained through the restorative effort, the Park authorities are planning to convene an international seminar, in November 1997, to which representatives of other internationally important wetlands, including those which are designated as World Heritage, are expected to be invited.
Analysis and Conclusion
The Committee may review new information expected to be available at the time of its session and decide whether Everglades National Park should be retained in the List of World Heritage in Danger.

VII.22 Everglades National Park (United States of America)
The Committee recalled that at its last session (Merida, 1996), it noted significant progress made with regard to acquisition of land, refinement of ecological indicators, and generous Federal and State allocations of financial and human resources, but decided to retain this site in the List of World Heritage in Danger due to continued prevalence of threats. In response to the Committee's call to the State Party to share knowledge and experience gained through the restorative effort, the Park authorities convened an international seminar, in November 1997, to which all western hemisphere World Heritage site managers were invited.
The Centre informed the Committee that a site monitoring report on the Everglades National Park was provided by the State Party on 25 November 1997, which indicated progress in the organization, planning and implementation of the ecosystem restoration projects in the region since the last report reviewed by the Committee in December 1996. In addition, significant amounts for ecological research and the purchase of land were made available by the Government.
After discussing whether the site could be removed from the List of World Heritage in Danger, the Committee noted that the Delegate of the United States of America indicated that the site is still under threat despite significant progress made. The Committee congratulated the Government of the United States on its progress and commitment and decided to retain Everglades National Park in the List of World Heritage in Danger.

Detailed List of SOC reports
Inscription on the Danger ListYear: 2010
Threats to the Site:
The property was re-inscribed on the List of World Heritage in Danger, on the request of the State Party, due to concerns that the property's aquatic ecosystem continues to deteriorate, in particular as a result of:
- Alterations of the hydrological regime (quantity, timing, and distribution of Shark Slough inflows);
- Adjacent urban and agricultural growth (flood protection and water supply requirements that affect the property's resources by lowering water levels);
- Increased nutrient pollution from upstream agricultural activities;
- Protection and management of FloridaBay resulting in significant reduction of both marine and estuarine biodiverstiy.
Year: 1993 -2007
Threats to the Site:
The site was inscribed on the List of the World Heritage in Danger in 1993 after the park's Superintendent informed the Committee of extensive damage to Everglades' ecology due to a number of causes including:
- nearby urban growth,
- pollution from fertilisers,
- mercury poisoning of fish and wildlife,
- a fall in water levels caused by flood protection measures.
In addition, on 24 August 1992, Hurricane Andrew altered much of Florida Bay and its ecological systems and destroyed the park's visitor centre.
The threats indicated are listed in alphabetical order; their order does not constitute a classification according to the importance of their impact on the property.
Furthermore, they are presented irrespective of the type of threat faced by the property, i.e. with specific and proven imminent danger (“ascertained danger”) or with threats which could have deleterious effects on the property’s Outstanding Universal Value (“potential danger”).
