Black Mangrove (Avicennia germinans) is very widely distributed along tropical silty seashores of Bermuda; throughout most of the West Indies; in the southeastern U.S. along both coasts of northern Florida to the Florida Keys, Mississippi, Louisiana, and Texas; along both coasts of Mexico south along Central America to Ecuador, northwestern Peru, the Galapagos Islands, and Brazil; and along the west coast of Africa. (Little and Wadsworth 1964)
The Black Mangrove (A. germinans) is distributed along the tropical and subtropical coasts of the American continent, the Caribbean islands, and West Africa. Three geographical units can be defined, including east Pacific (American Pacific), west Atlantic (American Atlantic and Caribbean), and east Atlantic (West Africa) (Nettel and Dodd 2007)
Avicennia germinans is a widespread mangrove species occupying the west coast of Africa and the Atlantic and Pacific coasts of the Americas from the Bahamas to Brazil and Baja California to Peru (Dodd et al. 2002).
Black Mangrove reaches its northern limit in the northern hemisphere in Florida, Louisiana, and Texas, where in recent decades it has been moving northward into temperate salt marshes typically dominated by the salt marsh grass Spartina alterniflora. In Louisiana marshes, Black Mangroves were historically restricted to the southernmost barrier islands and beaches by winter freeze events. However, in recent years freeze-free winters have facilitated a noticeable expansion of Black Mangrove northward into Spartina marshes. Nearly two decades of warm winter temperatures in coastal Louisiana have facilitated this northward expansion. (Perry and Mendelssohn 2009)
