As of 2010 those of (non-Hispanic white) European ancestry accounted for 57.9% of Florida's population Out of the 57.9% the largest groups were 12.0% German (2,212,391) 10.7% Irish (1,979,058) 8.8% English (1,629,832) 6.6% Italian (1,215,242) 2.8% Polish (511,229) and 2.7% French (504,641) White Americans of all European backgrounds are present in all areas of the state in 1970 non-Hispanic whites were nearly 80% of Florida's population Those of English and Irish ancestry are present in large numbers in all the urban/suburban areas across the state Some native white Floridians especially those who have descended from long-time Florida families may refer to themselves as "Florida crackers"; others see the term as a derogatory one Like whites in most other states of the southern U.S. they descend mainly from English and Scots-Irish settlers as well as some other British American settlers. .

The Everglades hosts 1,392 exotic plant species actively reproducing in the region outnumbering the 1,301 species considered native to South Florida the melaleuca tree (Melaleuca quinquenervia) takes water in greater amounts than other trees Melaleucas grow taller and more densely in the Everglades than in their native Australia making them unsuitable as nesting areas for birds with wide wingspans They also choke out native vegetation More than $2 million has been spent on keeping them out of Everglades National Park, With the rise of sea levels that occurred during the Pleistocene approximately 17,000 years ago the runoff of water from Lake Okeechobee slowed and created the vast marshland that is now known as the Everglades Slower runoff also created an accumulation of almost 18 feet (5.5 m) of peat in the area the presence of such peat deposits dated to about 5,000 years ago is evidence that widespread flooding had occurred by then. 4 Formative and sustaining processes There are three species of trees that are considered mangroves: red (Rhizophora mangle) black (Avicennia germinans) and white (Laguncularia racemosa) although all are from different families All grow in oxygen-poor soil can survive drastic water level changes and are tolerant of salt brackish and fresh water All three mangrove species are integral to coastline protection during severe storms Red mangroves have the farthest-reaching roots trapping sediments that help build coastlines after and between storms All three types of trees absorb the energy of waves and storm surges Everglades mangroves also serve as nurseries for crustaceans and fish and rookeries for birds the region supports Tortugas pink shrimp (Farfantepenaeus duorarum) and stone crab (Menippe mercenaria) industries; between 80 and 90 percent of commercially harvested crustacean species in Florida's salt waters are born or spend time near the Everglades.
