Executive summary
Atlas holds 131,999 mapped features and 37,971 observations in 26 datasets. The mapped mangrove canopy covers 8,111 ha in 4,458 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 70.1% 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.

Spatial clustering
Global Moran’s I = 0.173 (z = 3.1, p = 0.002). Hot-spot cells (Gi*, ≥95%): 9; cold-spot cells: 6.

Methods & limits
Areas and lengths are recomputed on the WGS 84 ellipsoid; units are harmonised (ha, m, %, UTC). The mapping is a single 2019 epoch; the source publishes no licence; field plots are a sample; scenario figures are illustrative assumptions. Cite the original publishers listed above.
