Assessment Rationale:

This species has a relatively restricted extent of occurrence of 400 km2. Even though it is found in 16 locations at the moment, urbanisation is an ongoing process in the area and thus might affect the habitats of several subpopulations. Thus, the quality of the habitat, number of locations, number of sub-populations or the number of mature individuals are probably declining, further monitoring of the status is urgently required. Therefore, it is assessed as Near Threatened (NT), almost qualifying for Vulnerable (VU) B2ab(ii,iii).

Geographic Range:

This species is present on Gran Canaria, where it is widespread in the northern parts of the island. However, the subpopulations are separated, which results in a fragmented area of distribution.

There are no data on the population size or trend. The population is thought to be stable.

Habitat and Ecology

This species lives in the humid parts of the local pine forests (Pinar) and in the relics of Laurel forests (Laurisilva), which is restricted to the northern parts of the island. Furthermore it is found in Fayal-Brezal, in deep barrancos, and in humid anthropogenic habitats.

Major Threat(s):

Potential threats to this species are destruction of the habitat by quarrying, urbanisation, road construction or by other reasons. Fragmentation is partly caused by increasing urbanisation and overall land use. Urbanisation is an ongoing process in the area and thus might affect the habitats of several subpopulations.

Conservation Actions

Only few subpopulations are under local conservation schemes. Monitoring is suggested to follow the population trends of this species. Valido et al. (1999) estimated its status as LR/lc (low risk).
