Indus River Delta–Arabian Sea mangroves

The Indus River Delta-Arabian Sea mangroves are a large mangrove ecoregion on the Arabian Sea coast of Sindh Province, Pakistan, and the Gulfs of Kutch and Khambhat in Gujarat, India. The mangroves are the seventh largest mangrove forest in the world.

The Indus River Delta forms a vast alluvial fan composed of mud flats interspersed with channels and fringed with mangrove forests. The delta has gotten significantly smaller in the 20th century as development and coastal management practices reduce the resilience of the delta. The delta had 16% cover by mangroves in 1990, and has decreased by 10% by 2017.

Much of the forested area has been destroyed and the remaining parts are threatened, in part because practices like dykes make the land no longer suitable for mangroves, and encroachment by communities harvesting mangrove wood. Other threats include pollution and oil spills from the city of Karachi.
