Justification of Red List category
This species has a small range and a moderately small population. The taxon F. t. polatzeki of Gran Canaria is rare and highly threatened, but the area of suitable habitat on Tenerife (the majority of the range) is increasing overall, which suggests that the population is also increasing, and the range is not severely fragmented. However, forest fires remain a serious and plausible potential threat and have the potential cause a rapid population decline which would warrant the species being uplisted to Vulnerable or Endangered. For this reason, the species is classified as Near Threatened. Were appropriate action to be taken which reduces the risk of serious fires such that they no longer represent a plausible threat, the species may be eligible for downlisting to Least Concern in the future.
