WDPCA Polygon Records

Live query snapshot from the official WDPCA polygon layer on ${comparisonSnapshot.date}.

${comparisonSnapshot.wdpcaPaSubset.toLocaleString()}

WDPCA Records Tagged As PA

This is the protected-area subset inside WDPCA.

${comparisonSnapshot.wdpcaOecmSubset.toLocaleString()}

WDPCA Records Tagged As OECM

These are the additional conserved-area records that extend beyond WDPA.

Legacy WDPA Polygon Records

The WDPA polygon count matches the WDPCA site_type = PA subset in the current live services.

Official Framing

\n Protected Planet describes the\n WDPCA service\n as the combined product for protected areas and OECMs. The legacy\n WDPA thematic view\n remains the protected-area-only subset.\n

\n IBAT also documents WDPCA as one of its core biodiversity source datasets:\n IBAT WDPCA dataset page.\n

Relationship To WDPA

WDPA: protected areas only.
WDPCA: protected areas plus OECMs in one product.
Practical reading: if you need continuity with older protected-area-only workflows, WDPA still describes that subset; if you need the broader protected-and-conserved-area picture, WDPCA is the better starting point.
Current live-service comparison on March 23, 2026: WDPCA = 306,669 PA records + 7,376 OECM records, while WDPA = 306,669 protected-area records.

How To Read The Map

WDPCA layer: official Protected Planet styling. It includes both protected areas and OECMs.
Legacy WDPA polygons: shown here as a magenta outline so the protected-area-only footprint can be compared against the broader WDPCA view.
Interpretation: where the WDPCA layer extends beyond the WDPA outline, you are seeing the newer protected-and-conserved-area framing rather than the older protected-area-only subset.
