14 of 9 themes have no data yet

Atlas holds no records for: Salt Marsh, Coastal Forests, Blue Carbon, Restoration Sites, Carbon Projects, Biodiversity, Land Use & Land Cover, People & Settlements, Wildlife & Habitats, Fire & Climate, Farming & Livelihoods, Mining, Oil & Licences, Surveys & Field Data, Boundaries & Reference. Seagrass and salt marsh would come from UNEP-WCMC global datasets; carbon projects from the Verra and Gold Standard registries; community projects from partner programmes.

Suggested action: Ingest the planned sources listed in the Source Catalogue, starting with Global Mangrove Watch, UNEP-WCMC seagrass and salt marsh, and the carbon registries.

Licence terms to be confirmed for 5 datasets

Licence terms are being confirmed with the publisher. Atlas holds the data for scientific and internal use and shows the original attribution, but cannot grant bulk redistribution rights.

Suggested action: Request written permission from WWF Kenya, KMFRI and KFS for redistribution and derivative products.
Evidence and method
datasets without licence

Most polygons are very small, but most area sits in large stands

32.5% of the 443 mapped polygons are under 0.1 ha, yet patches of 10 ha or more hold 15.1% of all mangrove area. Management and monitoring effort should focus on the large stands, while the small-patch tail needs checking against satellite imagery.

Suggested action: Prioritise field verification of large stands; review the sub-0.1 ha tail for mapping artefacts.

Net gain of mangrove since 1996

Global Mangrove Watch maps 300 ha of mangrove in Mauritius in 1996 and 445 ha in 2025: a net gain of 145 ha (48.2%), about 5 ha per year. This is the net balance of total mapped area; gains and losses inside the country can cancel out, so real loss may be larger.
