Berberis bicolor

Unknown

Overview

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

Berberis bicolor faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development in its native Andean cloud forest regions. Overgrazing by livestock has degraded the understory vegetation where this shrub naturally occurs, while climate change is shifting the altitudinal zones of suitable cloud forest habitat upward beyond the species' current range.

Threat summary

Habitat

Berberis bicolor inhabits Andean cloud forests and montane scrublands at elevations between 2,500-3,500 meters. The species thrives in the humid, mist-shrouded understory of these high-altitude ecosystems, particularly in areas with well-drained soils and partial shade.

Why is Berberis bicolor classified as Endangered?
Berberis bicolor 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. Berberis bicolor faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development in its native Andean cloud forest regions. Overgrazing by livestock has degraded the understory vegetation where this shrub naturally occurs, while climate change is shifting the altitudinal zones of suitable cloud forest habitat upward beyond the species' current range.
Where does Berberis bicolor live?
Berberis bicolor 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 Berberis bicolor?
The main threats to Berberis bicolor 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.
