This PDD is for the Nayarit restoration project VCS 2842, not BlueMX’s wider Mexico portfolio or separate conservation initiative. The registry and PDD differ on some project details; both readings are kept visible.

The Verra record and public PDD were reviewed. Filed forecasts, boundaries, tenure and benefits are presented as design claims, not verified outcomes. The initial area differs by one hectare between PDD and registry; registry and PDD crediting periods, annual estimates and Ejido counts also differ. PDD maps and figures remain at source; project gallery images are published on the BlueMX Mangrove profile by Ma Earth.

Filed estimates are ex ante. They are not verified removals or issued credits.

Where the registry and PDD differ, both source readings are shown and the difference remains open.
