Bu Tinah is a tiny archipelago amid extensive coral formations and seagrass beds some 25 km (15.5 miles) south of Zirku and 35 (22 miles) north of Marawah in the United Arab Emirates. Found in the waters of Abu Dhabi, it is protected as a private nature reserve.

Bu Tinah Island, rich in biodiversity, lies within the Marawah Marine Biosphere Reserve with a territory of more than 4,000 km2. The biosphere reserve is the region's first and largest UNESCO-designated marine biosphere reserve. It has been a recognized UNESCO site since 2001. It is closed to visitors and fishing and the collection of turtle eggs are prohibited on Bu Tinah Island; the ban being enforced by patrols.

The waters of the Persian Gulf are among the most saline in the world, as well as among the warmest.

Bu Tinah’s thriving habitat is a unique living laboratory, with key significance for climate change research. This distinctive natural habitat with its shallow waters, seagrass beds and tall mangroves, set amid extensive coral reefs, hosts rare and globally endangered sea life. The island’s waters are home to the planet’s second-largest population of dugong, a large marine mammal that is globally threatened. Some 600 out of the estimated 3,000 dugongs in the country live in the waters around Bu Tinah and the creatures are listed as a species vulnerable to extinction by the IUCN.
