Thriving mangroves are key to the health of nature and effective climate action. It is estimated a total of 15.2 million hectares of mangroves are exist worldwide and their main distribution is in the tropical areas. Forty species of mangroves dominate approximately 75% of the world’s tropical coastlines between 25° N and 25° S. In certain locations, this range extends beyond these limits due to the movement of unusually warm waters from the equator. Source: Okinawa, … GLAS lidar altimetry data were collected globally from 2003 to 2009, providing the only global lidar canopy and height measurement, with sparse samples distributed across the globe. Maps of the three data products are provided for each of 116 countries. The distribution of mangroves has been mapped through the Queensland wetland mapping and more details can be found in the intertidal and subtidal mapping. The research, published in PNAS, found that mangrove poleward expansion and the changes in community … The total aboveground carbon stocks per country were calculated assuming a stoichiometric factor of 0.451 as the AGB conversion factor. Mangrove forests are among Earth's most threatened ecosystems, yet the human and natural causes of their loss have not been quantified at the global scale. Mangroves comprise several species of trees and shrubs that grow along sheltered intertidal shores, mainly in tropical & subtropical coastal waterways.
