Mangroves: the coast's living defence
Tangled roots, salty mud and very few visitors. Mangrove forests are easy to overlook and among the most useful habitats on the coast.

Mangroves are trees that have learned to live where almost no other tree can: in salt water, in mud that floods twice a day. Their roots arch out of the water to hold the trunk steady and to breathe.
Those roots slow the tide. Sediment drops out of the water, the shoreline builds up rather than washing away, and the water that reaches the sea is clearer, which helps the seagrass and reefs further out.
A nursery for the sea
Between the roots, young fish and crustaceans find shelter from predators. Many species that are later caught offshore spend their first months here, so the health of a mangrove forest shows up, eventually, in a fisherman's catch.
When mangroves are cleared for building, firewood or ponds, the coast loses all of this at once: protection, nursery habitat and the carbon stored in the mud beneath them.
