Mangroves are salt-tolerant trees and shrubs that grow in the intertidal zone between land and sea in tropical and subtropical regions. They form complex ecosystems that provide coastal protection from erosion and storms. Mangroves have specialized adaptations for survival in salty, anoxic soils, including aerial roots and mechanisms for salt exclusion. They support rich biodiversity and serve as nurseries for many marine species. Mangroves also provide economic benefits through wood products, fisheries, and ecosystem services. However, they are threatened by conversion to aquaculture and agriculture.
