Assessment Rationale:

The Hierro Rock Grasshopper is endemic to El Hierro, where it occurs on steep rocky slopes. The information on habitats, population trends and threats is scarce, but it is probably common as its habitat is little affected by human activities. The species is therefore assessed as Least Concern (LC).

Geographic Range:

The Hierro Rock Grasshopper is endemic to the island of El Hierro, Canary Islands, Spain (Hochkirch and Görzig 2009). Even though the number of known sites of this species is low, it is assumed to be much more common as its ecology is likely to be similar as in related Arminda species on La Gomera, Tenerife and La Palma. Assuming that the species occurs throughout the island, the maximum extent of occurrence (EOO) is 371 km².

There is no information available on the population size of this species. However, it is probably quite widespread and common as it occurs in habitats that are little affected by humans. The population trend is unknown.

Habitat and Ecology

Information on the habitat and ecology of Arminda hierroensis is scarce, but similar to other Arminda species it seems to occur mainly on steep rocky slopes.

Major Threat(s):

Based upon its habitat preferences, it is assumed that no major threats caused by human activities affect this species. However, it might be affected by natural threats such as volcanism and avalanches.

Conservation Actions

No specific conservation measures are in place, although it occurs in protected areas. More research into its distribution, population trend, ecology and threats is needed.
