The improvement in the conservation status of several terrestrial snails endemic to the Canary Islands is the result of a joint project developed by the Loro Parque Foundation and the CanBIO project, in collaboration with the International Union for Conservation of Nature and the University of La Laguna, and co-financed by the Government of the Canary Islands. After more than a decade without updated information, this work has made it possible to reassess numerous species and adjust their threat category on the IUCN Red List, reflecting real progress in their conservation.
Hemicycla mascaensis
This species, endemic to Tenerife, has improved its conservation status from Critically Endangered (CR) to Near Threatened (NT), thanks to new information on its distribution and population status.
Monilearia arguineguinensis
Endemic to Gran Canaria, this species has been downlisted from Critically Endangered (CR) to Endangered (EN) after its situation was found to be more favourable than previously estimated.
Vitrinula festinans
Endemic to La Palma, this species has been downlisted to Vulnerable (VU) following the rediscovery of previously unknown populations.
Hemicycla efferata
Also endemic to La Gomera, this species has improved its status from Critically Endangered (CR) to Near Threatened (NT).
Napaeus arinagaensis
Also endemic to Gran Canaria, this species has improved its status from Critically Endangered (CR) to Vulnerable (VU), reflecting greater population stabili.
Canariella ronceroi
Endemic to La Gomera, this species has been downlisted to Vulnerable (VU) thanks to new population data.
