Summary
Salt-tolerant coastal trees that protect shorelines and nurse young fish.
In depth
Adaptations: salt excretion, prop roots and pneumatophores for oxygen in waterlogged soils. They store large amounts of carbon, reduce storm impact and nurse juvenile fish. Lost at about 1 to 2 percent a year in many regions.
Dense roots trap sediments and slow waves. Mangroves store carbon in anaerobic mud. Shrimp farming drives losses.
Example: restoration projects in Vietnam reduced storm damage costs.
Mangroves are salt-tolerant trees and shrubs that grow in tropical and subtropical intertidal zones. Adaptations include prop or stilt roots for support, pneumatophores that stick up to take in air in waterlogged mud, salt-excreting leaves and viviparous seedlings that germinate on the tree.
They protect coasts from storms and erosion, trap sediment, filter pollutants, store huge amounts of carbon (blue carbon) and are nurseries for fish, crabs and shrimp. Threats include clearing for shrimp farms, development and rising sea levels.
Example: the Sundarbans in Bangladesh and India is the world's largest mangrove forest.
Key idea: protecting mangroves is cheaper and more effective than seawalls in many places.

How is Mangroves different from Deforestation?
Mangroves: Salt-tolerant coastal trees that protect shorelines and nurse young fish. Deforestation: Clearing forests destroys habitats, releases carbon and disrupts water cycles. Read both side by side and note what each one explains.
How should I study Mangroves step by step?
