MANGROVES....

Mangroves are trees and shrubs that grow in tropical and subtropical tidelands throughout the
world. Mangroves grow in areas that are frequently inundated with salt water due to tidal activity of gulfs, seas and oceans. Mangroves are able to thrive salt water inundation because of specialized rooting structures (such as prop roots and pneumatically), specialized reproduction (viviparous or live birth) and the ability to exclude or excrete salt. Mangroves grow exclusively in these tidal areas in large stands or groves to where these areas are referred to as their own ecological community, collectively called mangroves.

In Florida, mangroves include four tree species: red mangrove (Rhizophora mangle), black mangrove (Avicennia germinans), white mangrove (Laguncularia racemosa) and buttonwood (Conocarpus erectus). Each mangrove species has a different level of salt tolerance, which in part determines its location in tidal zones.
