Salt marsh ecosystems can be found around the globe between the tides in protected coastal waters. Moving from the poles to the equator, their distribution is bounded by the subtropics (25šN and 25šS latitude), where salt marshes give way to mangrove ecosystems (Chapman 1977, Greenberg et al. 2006). They are found on all continental coasts (excepting Antarctica), and in temperate regions (from 66.5šN and 66.5šS to the subtropics) are most extensive along the Gulf of Mexico and southwestern Atlantic coasts of North America, totaling 15,000 square kilometers.
