Assessment Rationale:

This species is found on Gran Canaria, where it is known from a single site in a degraded laurisilva forest. The quality of its habitat is declining, as there is a continuing use of the forest for agricultural purposes. This species is therefore assessed as Critically Endangered (CR) B2ab(iii). The creation of protected areas, restoration of the habitat and monitoring of habitat trends are required to establish the future status of the species.

Conservation Actions

Moliner Gomez et al. (2001) listed as Near to Extinction and Valido et al. (1999) proposed the species as Critically Endangered. This species is included as Vulnerable D2 on the Red List of Spain (Verdu and Galante 2006). They proposed the creation of protected areas and restoration of the habitat. Monitoring of future trends in habitat are required to establish the future status of the species.
