U.S. Congress in Fiscal Year 2016. Ecology The Experimental Oculina Research Reserve preserves the Oculina Banks, a reef of ivory bush coral (Oculina varicosa) off the coast of Fort Pierce, Florida. In 1984, a 92 square-nautical-mile (316 km2) portion of these reefs was designated the "Oculina Habitat Area of Particular Concern". In 1994, the area was closed to all manner of bottom fishing and was redesignated as a research reserve. In 2000, the marine protected area was expanded to 300 square nautical miles (1,030 km2) and prohibited all gears that caused mechanical disruption to the habitat. The city is also known for its large manatee population. Marina Due to the devastation caused at the Fort Pierce City Marina by hurricanes Frances and Jeanne in 2004, FEMA mandated a plan to ensure that the rebuilt facility would be protected from future such events before FEMA would release funding for the repairs. Starting in 2012, construction began to create 12 artificial barrier islands including oyster beds, lime rock artificial reefs, mangrove fringes and coastal dune. The "core" of the islands was constructed of TITANTubes, sometimes referred to as geotextile tubes or geotubes, manufactured by Flint Industries and covered by a coastal marine mattress and then armor stone. The project was completed in 2013 after six years of planning, permitting and construction and a cost of $18 million. Climate Fort Pierce has a humid subtropical climate, with hot, humid summers and warm, drier winters. Demographics 2020 census Note: the US Census treats Hispanic/Latino as an ethnic category.
