Executive summary
Atlas holds 70,345 mapped features and 23,095 observations in 23 datasets. The mapped mangrove canopy covers 3,778 ha in 564 polygons across 1 formation classes; Mangrove dominates with 100.0% of the area. The median patch is only 0.357 ha, while patches of 10 ha or more hold 85.8% 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.
