Assessment Rationale:

This species is known from a restricted area on the north-east part of Tenerife (extent of occurrence of 100 km2), but it is known from 16 locations. Its range is currently under pressure because of rapid and increasing urban development (city of St. Cruz de Tenerife). It is therefore considered to be Near Threatened (NT), almost meeting criteria B.

Geographic Range:

This species is endemic to the island of Tenerife. It lives in the southern parts of the island (southern slopes of Anaga Mountains, St. Cruz).

Population:

Habitat and Ecology

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

Major Threat(s):

This species is declining due to urbanisation, as well as quarrying close to the city for building stone, road construction.

Conservation Actions

Roughly one third of the population is under local conservation. Enlargement of existing protected areas is needed, and the further development of the city of St. Cruz has to be regulated.
