Figure 7 Total carbon stock of Abu Dhabi Blue Carbon (and candidate and associated) Ecosystems & Summary of carbon stock in Blue Carbon, candidate and associated ecosystems in Abu Dhabi.

How these values compare to non-arid regions Compared with other dominantly non-arid regions of the world, carbon stocks per unit area in Abu Dhabi are at the low end of the range. Typical ranges for total carbon stock are

270-2,200 tonnes/ha (mangrove) 115-480 tonnes/ha (salt marsh) 50-380 tonnes/ha (seagrass)

Although carbon values for Abu Dhabi’s Blue Carbon ecosystems are at the low end of the global scale, this carbon stock is likely to be the largest of any natural ecosystem in the emirate and should these ecosystems be destroyed, significant carbon dioxide (CO 2 ) would be emitted.
