Assessment Rationale:

The species is only known from six locations in a small area of the Anaga Mountains (area of occupancy of 48 km²), in an degraded forest area which requires habitat conservation, management and restoration in order to protect the species. This species is listed as 'Sensitive to habitat disturbance' on the Spanish Red List by Gomez et al. (2001). Actions recommended include the provision of a protected area for this area of Anaga mountains. The species is considered as Vulnerable (VU) B2ab(iii).

Geographic Range:

This species is endemic to the Canary islands where it is restricted to Tenerife, known only on the northern slopes of the Anaga Mountains. Only known from northern slopes so restricted to this area.

Population:

This species is thought to be stable, as it mostly occurs in protected area of Laurisilva and Fayal-Brezal in the Anaga mountains.

Habitat and Ecology

This species lives in the edges of the laurisilva forest degraded with small bushes of tree heather (Erica arborea). It is restricted to this vegetation on steep slopes.

Major Threat(s):

Impact of forest management on the laurisilva zone over less than 50% of the area leads to some decline of the habitat.

Conservation Actions

The habitat requires conservation, management and restoration in order to protect the species. This species is listed as 'Sensitive to habitat disturbance' on the Spanish Red List by Gomez et al. (2001), but is not on the register of Endangered Species for Canary Islands, nor the Spanish Red List (Verdu and Galante 2006) and there is no legal protection. Actions recommended include the provision of a protected area for this area of Anaga mountains.
