Assessment Rationale:

This species is restricted to Madeiran islands where it is found at widely scattered locations in the coastal regions of Madeira. It is often abundant at sites. The present population abundance, number of sites, the widespread presence over the island and its presence in degraded habitat, suggests that this species is not highly threatened. The mainland populations are susceptible, given the multiple threats causing habitat degradation and impact of non-native species. However, the species is currently viewed as Least Concern (LC), based on current habitat and threats.
