Bonnetia cordifolia
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Bonnetia cordifolia faces significant pressure from habitat conversion as tepui summit ecosystems are increasingly fragmented by mining activities and infrastructure development. The species' extremely restricted range on isolated mountaintops makes populations particularly vulnerable to climate change, as warming temperatures force suitable habitat zones upward with nowhere left to retreat. Fire regimes altered by human activity pose an additional threat to the specialized shrubland communities where this species occurs.
Habitat
Bonnetia cordifolia is endemic to the unique tepui (table mountain) ecosystems of the Guiana Highlands, specifically occurring in montane shrublands and rocky outcrops on isolated summit plateaus. These specialized habitats are characterized by nutrient-poor soils, high rainfall, and frequent cloud cover, creating distinct microenvironments that support highly endemic flora.
