Generated 13 November 2026, 02:58 from live Atlas data
Executive summary
Atlas holds 374,330 mapped features and 295,035 observations in 92 datasets. The mapped mangrove canopy covers 212,245 ha in 5,630 polygons across 1 formation classes; Mangrove dominates with 100.0% of the area. The median patch is only 0.089 ha, while patches of 10 ha or more hold 98.9% 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.
