Berberis johannis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Berberis johannis faces significant pressure from habitat conversion as its montane forest ecosystems are cleared for agricultural expansion and livestock grazing. The species' restricted range in the Andean highlands makes it particularly vulnerable to localized disturbances, while climate change threatens to shift suitable habitat zones upslope beyond the species' adaptive capacity. Collection pressure for ornamental and medicinal uses may also impact remaining populations.
Habitat
Berberis johannis inhabits montane cloud forests and humid woodland edges in the Andean highlands, typically occurring at elevations between 2,500-3,500 meters. The species favors areas with consistent moisture and partial shade, often growing along forest margins and in secondary growth areas.
