India’s first Marine Wildlife Sanctuary and first Marine National Park were created here in the Gulf of Kutch in 1980 and 1982, respectively. The sanctuary covers 458 sq km, of which the park covers 163 sq km. The sanctuary lies in the inter-tidal zone, between the lowest and highest tide levels, the area that lies below water in high tide, and is exposed during low tide.
This gives us a chance to observe the richest diversity of marine habitats in the country, including saline grasslands, marshy areas, rocky shores, mudflats, creeks, estuaries, sandy strands, coral reefs, and mangroves. The latter two are an essential part of not only the local environment, but also the stability and diversity of the planet; they are unfortunately severely degraded in many parts of the world. During the Tsunami in 2004, the few areas that were still protected and had mangrove forests intact made it dramatically apparent how important this was, in comparison to the areas that were open and vulnerable.
Coral reefs
Some of the finest coral reef fringe islands are found at Pirotan, Narala, Ajad and Positara, often a surprise even to Gujaratis.
Coral is made of millions of colorful little animals called polyps, bound together by algae and other plants, in a variety of intriguing shapes and formations. The polyps breath out carbon dioxide, while the binding plants release oxygen, with a high nutrient turnover equivalent to a tropical rainforest. The rock-like formations provide shelter and safe breeding grounds for various tiny marine species in hiding from larger predators.
Poshitara, near Dwarka is a heaven for marine enthusiasts.
