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. Pneumataphores 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. Valued as a shoreline stabilization plant. Can also be used for screening.

The Emerald Ash Borer (Agrilus planipennis)is a very destructive wood-boring beetle native to Asia. It was discovered in North America in July 2002, and has become established in Michigan, New York, Ohio and Ontario (Canada). Millions of ash trees have been killed in the northeastern US. Although the borer has not been detected in Florida (Dec. 2011), the presence of ash trees and the ongoing movement of wood, trees and cargo into the state make Florida an area where the beetle could potentially become established. Your help is needed to detect possible infestations so they can be quickly eradicated...if you see it, contact the Florida Division of Forestry. Shade tree.
