Rosalia alpina

Overview

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

The Rosalia longicorn faces severe population declines primarily due to intensive forest management practices that remove dead and dying beech trees essential for larval development. Climate change compounds these pressures by altering montane forest composition and reducing the availability of suitable host trees. Habitat fragmentation isolates remaining populations, limiting genetic exchange and reducing colonization potential for new suitable sites.

Threat summary

Habitat

Rosalia alpina inhabits old-growth and semi-natural beech forests in mountainous regions of Europe, typically at elevations between 500-1,500 meters. The species requires mature beech trees with substantial amounts of dead wood, fallen logs, and sun-exposed dying branches where larvae can develop over 2-4 years.

Frequently asked questions

Why is Rosalia alpina classified as Vulnerable?
Rosalia alpina is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. The Rosalia longicorn faces severe population declines primarily due to intensive forest management practices that remove dead and dying beech trees essential for larval development. Climate change compounds these pressures by altering montane forest composition and reducing the availability of suitable host trees. Habitat fragmentation isolates remaining populations, limiting genetic exchange and reducing colonization potential for new suitable sites.
Where does Rosalia alpina live?
Rosalia alpina occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Rosalia alpina?
The main threats to Rosalia alpina 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.
