Bonnetia ptariensis

Unknown

Overview

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

Bonnetia ptariensis faces severe threats from climate change, as its high-altitude tepui habitat is extremely vulnerable to warming temperatures that force species upslope with nowhere to retreat. Mining activities and infrastructure development on the tepuis pose additional direct habitat destruction risks. The species' extremely restricted range on a single tepui summit makes any disturbance potentially catastrophic for the entire population.

Threat summary

Habitat

This species is endemic to the summit areas of tepuis (table mountains) in the Guiana Highlands, specifically occurring in high-altitude shrublands and rocky outcrops above 2000 meters elevation. It inhabits the unique sandstone plateau ecosystems characterized by nutrient-poor soils, high UV exposure, and frequent cloud cover.
