Assessment Rationale:

The species is proposed as Vulnerable  (VU) D2, as it is restricted to a small area (3 locations with an area of occupancy of 12 km2) with disturbance from recreational activities leading to declining quality of habitat. However, given the abundance of the species and the fact that the habitat quality is not declining significantly at all sites, it is not considered to qualify for an Endangered category.

Geographic Range:

This species is endemic to the Canary Islands where it is restricted to a small region on the east coast of Gran Canaria.

Habitat and Ecology

This species inhabits the piso basal in dry conditions.

Major Threat(s):

The maint threat is the disturbance from recreational activities leading to declining quality of habitat.

Conservation Actions

Gomez Moliner et al. (2001) considered this species to be Vulnerable A2c (Version 2.3).  No actions were proposed other than conservation of the habitat. This species would benefit from limiting the impact of tourist activity and habitat monitoring.
