Executive summary

Atlas holds 153,658 mapped features and 37,971 observations in 31 datasets. The mapped mangrove canopy covers 480 ha in 237 polygons across 1 formation classes; Mangrove dominates with 100.0% of the area. The median patch is only 0.340 ha, while patches of 10 ha or more hold 47.0% 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.

Methods & limits

Areas and lengths are recomputed on the WGS 84 ellipsoid; units are harmonised (ha, m, %, UTC). The mapping is a single 2019 epoch; the source publishes no licence; field plots are a sample; scenario figures are illustrative assumptions. Cite the original publishers listed above.
