Mangroves in the U.S.A are found chiefly in Florida where they dominate coastlines south of Latitude 29° N. Local native species include Avicennia germinans, Rhizophora mangle, Laguncularia racemosa and Conocarpus erectus. There are a small number introduced species to be found in southern Florida including Lumnitzera racemosa and maybe the odd tree of Nypa fruticans. There are also plenty of the introduced but now naturalised mangrove associate Schinus terebinthifolia.
Further to the north and along the shorelines of the Gulf of Mexico there are only scattered stunted and shrub communities of Avicennia germinans. But as conditions warm up, these northern occurrences are expected to consolidate further.
No native species are found on the North American west coast of U.S.A, but around Mission Bay and San Diego you may catch the odd remnant sighting of Avicennia marina introduced from SE Australia a few decades ago. There has been an active program to eradicate this occurrence.
