Scientists have determined [from a long term stud] for the first time that Amazon’s waterlogged coastal mangrove forests, which are being clear cut for cattle pastures and shrimp ponds, store significantly more carbon per acre than the region’s famous rainforest.

The Brazilian mangrove forest fringes the entirety of the Atlantic Coast at the mouth of the Amazon, the largest river in the world with the largest mangrove forest. Although preservation of the Amazon rainforest has been the subject of intense awareness efforts over the last few decades, less attention has been paid to the Amazon mangroves….

….Mangroves are a group of trees and shrubs that live in tropical coastal intertidal zones. There are about 80 different species of mangrove trees. All of these trees grow in areas of waterlogged soils, where slow-moving waters allow fine sediments to accumulate. In these environments, mangroves sequester significant quantities of carbon that is stored for centuries….
