Executive summary
Atlas holds 139,661 mapped features and 37,971 observations in 27 datasets. The mapped mangrove canopy covers 20,124 ha in 5,140 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 87.4% 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.
