Location of Mangrove Forests
Mangrove forests exist between 25º north and 25º south for the most part. The main amount of their biomass is in this range, and the few exceptions to this are inconsequential. They exist on the borders of land and water, along the coastlines of many tropical peninsulas and islands. Mangrove forests account for 75% of the coastal vegetation in tropical and sub-tropical regions around the world. Because of the fact that they can only exist along the shorelines of land and salty water, their biomass is rather limited.
The red here represents the growth of mangrove forests. As you can see on the map shown above, they grow in the mid-latitude range in tropical and sub-tropical climates. A huge amount of the overall growth is in the Pacific region, especially around the borders of the islands of Indonesia and Thailand. Mangrove swamps tend to grow the most in locations that haven't been ravaged or developed by humans.
