Assessment Rationale:

Even though the Palma Rock Grasshopper has not been recorded very often on La Palma, it is assumed to be more widespread and the population is probably large. It does not appear to be threatened by human activities and it is therefore assessed as Least Concern (LC).

Geographic Range:

This species is endemic to La Palma, Canary Islands, Spain (Hochkirch and Görzig 2009). Its extent of occurrence (EOO) is between 450 and 700 km² and its area of occupancy (AOO) is estimated to be between 50 and 200 km².

Major Threat(s):

The habitat of Arminda palmae is currently not threatened by anthropogenic changes, but by the volcanic activities of La Palma.

Conservation Actions
