Mangrove forests were once generally dismissed as swampy wastelands. Planners, scientists, and coastal dwellers have now come to value them as the remarkably diverse and important ecosystems they are. Mangroves, seagrass beds, and coral reefs work as a single system that keeps coastal zones healthy. Mangroves provide essential habitat for thousands of species. They also stabilize shorelines, preventing erosion and protecting the land — and the people who live there — from waves and storms.
Keystone of a coastal ecosystem
Mangroves, seagrass beds, and coral reefs are often found together and work in concert. The trees trap sediment and pollutants that would otherwise flow out to sea. Seagrass beds provide a further barrier to silt and mud that could smother the reefs. In return, the reefs protect the seagrass beds and mangroves from strong ocean waves. Without mangroves, this incredibly productive ecosystem would collapse.
"Mangroves are like the kindergarten, seagrasses are the secondary schools, and coral reefs are the high schools and colleges for fishes! And, once [the fishes] graduate from university, they return to kindergarten to spawn."
