Mangroves, often called “nature’s guardians of the coast” or “rainforests of the sea,” are remarkable ecosystems that straddle the boundary between land and sea, providing a myriad of ecological and socio-economic benefits.

Selecting the right location for planting sets the foundation for successful mangrove restoration efforts.
