Perhaps the most unique attraction on Qeshm Island and the coasts of Persian Gulf for every domestic and foreign tourist is the floating mangrove forest. The forest goes underwater upon high tide and reemerges during low tide. Mangrove forest is made up of a tree called mangrove, which is called Timer in Sistan and Baluchestan, Toul in some southern parts of Iran, and Harra in Bandar Abbas. Arabs call it Shoura and Azam and its size varies from 3 meters to 6 meters. Its seed easily grows on the seabed. The seeds may also grow on the trunk of the parent tree before being detached from it to flow on the water. The salty water plant filters seawater retaining fresh water and repelling salt.
Mangrove forest displays high biodiversity and is a habitat for tropical birds. It is a haven for 150 various species of birds in cold seasons of fall and winter whose number sometimes exceeds hundreds of thousands. They include seagulls, cormorants, flamingoes, storks, pelicans, eagles and falcons. Apart from birds, mangrove forest is a good haven for a variety of other animals including various fish, sea snakes, crabs, clings, various frogs and even mammals. On the whole about 80 percent of aquatics in Persian Gulf spend their spawning time in the area of mangrove forest, which accounts for about 90,000 hectares. Apart from northwestern coasts of Qeshm, which host the bulk of Iran’s mangrove forest, they can also be found 3 km from Tiab port near Minab as well as in Jask region of Chabahar.
