Year: 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.
