IUCN Status

Considered to be facing a high risk of extinction in the wild.

Vulnerable - Considered to be facing a high risk of extinction in the wild.


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species groups, such as vascular plants or vertebrates, updates proposed to the IUCN are shown, rather than the outdated, but currently-used status;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.

Distribution

Only in Genovesa Island.
