Executive summary
Atlas holds 297,487 mapped features and 294,959 observations in 91 datasets. The mapped mangrove canopy covers 3,000 ha in 913 polygons across 1 formation classes; Mangrove dominates with 100.0% of the area. The median patch is only 0.178 ha, while patches of 10 ha or more hold 80.2% of the area. 0 ha (0.0%) lies within 10 km of the LAPSSET development footprint.
Single mapping epoch (2019). Areas are geodesic hectares recalculated from geometry.

Recommendations
High 8 of 9 themes have no data yet
Atlas holds no records for: Seagrass, Salt Marsh, Blue Carbon, Land Use & Land Cover, Wildlife & Habitats, Fire & Climate, Farming & Livelihoods, Surveys & Field Data. 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.
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.
High Licence terms to be confirmed for 77 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.
Action: Request written permission from WWF Kenya, KMFRI and KFS for redistribution and derivative products.
Medium Most polygons are very small, but most area sits in large stands
45.9% of the 913 mapped polygons are under 0.1 ha, yet patches of 10 ha or more hold 80.2% of all mangrove area. Management and monitoring effort should focus on the large stands, while the small-patch tail needs checking against satellite imagery.
Action: Prioritise field verification of large stands; review the sub-0.1 ha tail for mapping artefacts.
Low Net gain of mangrove since 1996
Global Mangrove Watch maps 2,590 ha of mangrove in Republic of the Congo in 1996 and 3,084 ha in 2025: a net gain of 494 ha (19.1%), about 17 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.
