Mangrove Habitat and Coastal Species Welfare

Mangrove forests are critical nursery habitats for marine species, and their loss to aquaculture and development removes welfare-supporting resources for thousands of marine animals.

Key Facts

Mangroves cover 14 million hectares globally but have declined by 50% in the last century
Shrimp farming has destroyed vast areas of mangrove in Southeast Asia
Mangroves provide nursery habitat for 80% of commercially important tropical fish species
Storm surge protection from mangroves reduces flood damage to coastal communities
Carbon sequestration from mangroves is 3-4 times higher per hectare than tropical forest

Welfare Considerations

Mangrove loss creates welfare harms for marine species throughout their life cycles: juvenile fish lose the sheltered, nutrient-rich nursery habitat that provides refuge from predation and abundant food. Species that depend on mangrove nurseries for early life development face lower survival rates in waters without this habitat. The welfare cascade from mangrove destruction extends from juvenile fish survival through to adult population health, affecting the welfare of millions of individual fish across the food web.

What You Can Do

Avoid farmed shrimp from regions with high mangrove conversion rates
Support Wetlands International and mangrove conservation organisations
Advocate for mangrove protection requirements in aquaculture permitting
Choose seafood from sources demonstrating low mangrove impact
Donate to mangrove restoration projects in key biodiversity areas
