First ever blue carbon in Seychelles mangrove ecosystems

An assessment of blue carbon in mangrove ecosystems of Seychelles has been undertaken for the first time and is now published.

Seychelles holds 2,195 ha of mangrove forests, with ∼80% of them found on the UNESCO World Heritage and RAMSAR sites of Aldabra, a protected coral atoll.

 Seychelles mangrove ecosystems store 688,091 ± 18,353 tonnes of organic carbon (or 2.5 million tonnes CO2e) and an average of 477.0 ± 16.2 tonnes of carbon per hectare, with 70% of their total carbon stocks stored in their soils.

Aldabra holds the highest total carbon stocks, accounting for 67% of Seychelles’ mangrove carbon, despite having a relatively shallow soil organic layer due to the dominance of limestone and coral. 

Seychelles currently protects ∼85% of its mangrove extent including Aldabra and Port Launay, a Ramsar site on Mahe Island.
