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.
