Justification of Red List category
This species has a small range and a moderately small population. The area of suitable habitat on Tenerife is increasing overall, which suggests that the population is also increasing, and the range is not severely fragmented. However, this species has a very small range which approaches the thresholds for Vulnerable under the range size criterion D2. Forest fires remain a serious and plausible potential threat and have the potential to cause a rapid population decline which would warrant the species being uplisted to Vulnerable or Endangered. The number of locations is believed to be higher than 5. The species is therefore assessed 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 Were appropriate action to be taken which reduces the risk of serious fires such that they no longer represent a plausible threat, the species may be eligible for downlisting to Least Concern in the future.
