Bonnetia rubicunda
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Bonnetia rubicunda faces significant pressure from habitat conversion as montane forests are cleared for agriculture and cattle ranching across its Venezuelan and Guyanese range. Mining activities, particularly gold extraction in the Guiana Highlands, directly destroy tepui summit vegetation where this species occurs. Climate change poses an additional threat as rising temperatures force montane species to migrate upslope, potentially eliminating suitable habitat on isolated tepui summits.
Habitat
Bonnetia rubicunda inhabits montane forests and tepui summit vegetation in the Guiana Highlands, typically occurring at elevations between 1,000-2,500 meters. This species is endemic to the unique sandstone table mountains (tepuis) of Venezuela and Guyana, where it grows in nutrient-poor, acidic soils characteristic of these ancient geological formations.
