General Comments:

The common name black mangrove is a reference to the color of the trunk and heartwood. The plant excretes salt from its leaves, an adaptation to a saline environment. Pneumatophores rise above the substrate and make this an important plant for coastline erosion prevention. This is a protected plant and you may not trim back or gather propagules without permission.
