Subspecies and varieties with no assessed parent species

Source: IUCN Red List 2026-1 (CSV export) · 358 rows

The table below lists assessed subspecies and varieties whose parent species has no species-level assessment in the current release. The IUCN API lists subspecies and varieties under their parent species, so when the parent has no assessment, the only way to reach these taxa through the API is by already knowing their SIS id. Each row links to the taxon's Red List page.

Why it matters

Tools and users browsing through the API never encounter these taxa, even though their assessments exist and are published.

Suggestion

Add a species-level assessment for the parent (e.g., 'Not Evaluated') so the infraspecific taxa become reachable, or provide another discovery route to them.

Change since 2025-2

Down from 383 in release 2025-2 to 358 in 2026-1.
