Through their thick networks of roots, mangroves provide coastal communities with a powerful defense against flooding and storms. In 2004, the Band La community in Thailand was spared the worst damage from a destructive tsunami because of its investment in mangroves. The resilience of the mangroves has gained the support of the national government and boosted local economies. Further, the restoration effort has brought endangered species back from the brink and helps to ensure the environmental integrity of the culture.
