Erysimum strictum

Local name: Vélar droit

Unknown

Overview

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

Erysimum strictum faces severe population decline due to habitat destruction from agricultural expansion and urban development across its limited Mediterranean range. The species is particularly vulnerable to quarrying activities that destroy its rocky habitat preferences, while invasive plant species compete for the specialized calcareous soil conditions it requires. Climate change poses an additional threat through altered precipitation patterns that affect the delicate moisture balance of its montane ecosystems.

Threat summary

Habitat

Vélar droit inhabits rocky slopes, limestone cliffs, and calcareous soils in Mediterranean montane regions, typically at elevations between 500-1500 meters. The species shows a strong preference for well-drained, alkaline substrates with sparse vegetation cover in semi-arid mountainous terrain.

Frequently asked questions

Why is Vélar droit classified as Endangered?
Vélar droit 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. Erysimum strictum faces severe population decline due to habitat destruction from agricultural expansion and urban development across its limited Mediterranean range. The species is particularly vulnerable to quarrying activities that destroy its rocky habitat preferences, while invasive plant species compete for the specialized calcareous soil conditions it requires. Climate change poses an additional threat through altered precipitation patterns that affect the delicate moisture balance of its montane ecosystems.
Where does Vélar droit live?
Vélar droit occurs in Åland Islands, Austria, Belgium, Denmark, Estonia, and Finland (plus 13 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Vélar droit?
The main threats to Vélar droit 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.
