Assessment Rationale:

This species is endemic to the island of Tenerife. This species is recorded from 9 locations and 14 sites, the extent of occurrence is 400 km2, however, the area of occupancy is quite limited to 36 km2. However, part of the species distribution occurs in a a protected area, and hence the threats related to the increasing urbanisation (and the resulting decrease in habitat quality and availability) affect half of the population. This species is therefore assessed as Vulnerable (VU) B1ab(ii,iii)+2ab(ii,iii).

Geographic Range:

This species is endemic to the island of Tenerife. It lives on the east coast of the island. This species is recorded from nine locations and 14 sites, the extent of occurrence is 400 km2, however, the area of occupancy is only 36 km2. The distribution area of the nominal subspecies is severely fragmented (half of the sites known for this species are impacted).

Habitat and Ecology

This species lives in the dry temperate shrub vegetation (Piso basal).

Major Threat(s):

Potential threats to this species are destruction of the habitat by quarrying, urbanisation, road construction. This particularly concerns the nominal subspecies, which lives in the fast developing south-eastern coastal area around St. Cruz de Tenerife. The subspecies C. f. beata is not affected since it lives in a protected area on the southern slopes of the Anaga mountains.

Conservation Actions

The subpopulations of the subspecies C. f. beata lives in a protected area on the southern slopes of the Anaga mountains. The nominate subspecies is not protected.
