Pre-Pyrenean Grasshopper

Omocestus navasi

DecliningENEUENEU

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Omocestus navasi faces severe population decline due to habitat degradation from agricultural intensification and urban development across its limited Mediterranean range. The species' specialized requirements for specific grassland microhabitats make it particularly vulnerable to land-use changes. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency, which directly impacts the vegetation structure this grasshopper depends upon.

Threat summary

Habitat

Omocestus navasi inhabits dry Mediterranean grasslands and scrublands, typically found in areas with sparse vegetation and rocky substrates. The species shows preference for open habitats with specific microclimatic conditions, often occurring on south-facing slopes with well-drained soils.

Frequently asked questions

Why is Pre-Pyrenean Grasshopper classified as Endangered?
Pre-Pyrenean Grasshopper is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Omocestus navasi faces severe population decline due to habitat degradation from agricultural intensification and urban development across its limited Mediterranean range. The species' specialized requirements for specific grassland microhabitats make it particularly vulnerable to land-use changes. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency, which directly impacts the vegetation structure this grasshopper depends upon.
Where does Pre-Pyrenean Grasshopper live?
Pre-Pyrenean Grasshopper occurs in France, and Spain. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pre-Pyrenean Grasshopper?
The main threats to Pre-Pyrenean Grasshopper are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
