IUCN Status

Not Evaluated - Not yet been evaluated against the criteria.

The IUCN Red List assessments presented here may deviate from the global IUCN listings for the following reasons:

  • for well-known species groups, such as vascular plants or vertebrates, updates proposed to the IUCN are shown, rather than the outdated, but currently-used status;
  • for poorly-known species groups, such as lichenized fungi, a general assessment is not currently possible, therefore the list presented here is the regional IUCN Red List for the Galapagos Archipelago.


Bioregions: Northern, South-eastern.

Galapagos island groups: Marchena, Santa Cruz.

South of Gulf of California to Peru including Galapagos Islands.
