Growing on the edge of land and sea, mangrove trees are adapted to an amazing range of environmental factors; they cope with changing salt levels, low soil oxygen, and ever-changing water levels. They protect shorelines against tsunamis and cyclones. Extensively illustrated, Field Guide to the Mangrove Trees of Africa and Madagascar identifies all the species found in Africa and provides a valuable insight into how they contribute to conservation, coastal defence systems, as a shelter for aquatic species, and as an important habitat type in its own right.
