Executive summary
Atlas holds 29,614 mapped features and 23,095 observations in 14 datasets. The mapped mangrove canopy covers 415 ha in 443 polygons across 1 formation classes; Mangrove dominates with 100.0% of the area. The median patch is only 0.252 ha, while patches of 10 ha or more hold 15.1% 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.
