Assessment Rationale:

The Tenerife Laurel Bush-cricket (Canariola willemsei) occurs in forests of Tenerife and La Gomera. Its extent of occurrence (EOO) is between 619 - 1,500 km², and its area of occupancy (AOO) is between 12 - 500 km². Even though the currently known number of locations is small (three), it is believed to be wider distributed. As it is close to qualify as threatened under Criterion B, it is assessed as Near Threatened. Further research on its taxonomy, population size and trend, habitats and ecology and threats is needed.

Geographic Range:

This species is endemic to La Gomera and Tenerife (Canary Islands, Spain) (Bland et al. 1996). Its known extent of occurrence (EOO) is 381 km², but its distribution is poorly documented and it may be more widespread. The maximum estimate of its EOO is 1,500 km². The known area of occupancy (AOO) is 12 km², with a maximum estimate of 500 km².

Habitat and Ecology

Canariola willemsei is an arboricolous species that occurs in laurel forests. Its altitudinal range is 500 - 1,100 m.

Major Threat(s):

The threats to this species are poorly understood. It may be threatened by increasing wildfire frequencies, but also by natural causes such as volcanism and landslides. The number of localities based upon the threat of wildfires is three, but it is probably wider distributed.

Conservation Actions

There are no specific conservation actions in place for this species, but large parts of its habitat occur in protected areas. Research on its taxonomy, ecology, distribution, population trend and threats is needed.
