Location of Katchal Island
Katchal island, which recently suffered a loss of 90% of mangrove cover due to the Indian Ocean Tsunami, is located in Nicobar Island.

Impact of the Indian Ocean Tsunami
The Indian Ocean Tsunami that struck in 2004 caused significant damage to the mangrove cover on Katchal island. The tsunami waves inundated the coastal areas, leading to the destruction of a large portion of the mangrove forests.

Significance of Mangrove Cover
Mangrove forests play a crucial role in coastal ecosystems as they provide protection against natural disasters like tsunamis and cyclones. They also serve as breeding grounds for various marine species and help in maintaining water quality.

Efforts for Restoration
After the devastation caused by the tsunami, efforts have been made to restore the mangrove cover on Katchal island. Various organizations and government agencies have initiated reforestation projects to replant mangrove saplings and rejuvenate the ecosystem.

Importance of Conservation
It is essential to conserve and protect mangrove forests not only for their environmental significance but also for the livelihoods of local communities that depend on these ecosystems for resources like fish and timber. Sustainable management practices and community involvement are key to ensuring the long-term health of mangrove ecosystems.
