BlueMX Aztlán Blue Carbon Project

The VCS 2842 PDD defines six initial activity instances across 5,417 ha, a larger proposed expansion, ex-ante carbon estimates and an annual nested-plot monitoring plan.

Project geography and imagery

The filed KML is mapped below. The regional satellite image is context, not evidence of restoration at a filed plot. PDD figures on physical pp. 11, 26 and 39 remain at source because reproduction rights were not established.

Filed geography

Six initial activity instances

The filed KML delineates six initial PAIs in Nayarit. Geodesic polygon area is about 5,424 ha; the PDD states 5,417 ha. Neither number is the wider 22,549-ha registry area field or proof of completed restoration.
