Navia graminifolia

Unknown

Overview

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

Navia graminifolia faces significant pressure from habitat degradation in the tepuis of the Guiana Highlands, where mining activities and infrastructure development fragment its specialized rocky outcrop ecosystems. Climate change poses an additional threat to this high-altitude endemic, as shifting temperature and precipitation patterns could alter the delicate moisture balance required for survival on exposed rock surfaces. The species' extremely restricted range and small population size make it particularly vulnerable to stochastic events and human disturbances.

Threat summary

Habitat

This bromeliad is endemic to the tepuis (table mountains) of the Guiana Highlands, specifically growing on exposed granite and sandstone rock faces and crevices at elevations between 1,500-2,800 meters. It thrives in the unique microclimate of these ancient geological formations, where it forms dense mats on vertical rock surfaces and benefits from frequent mist and cloud cover.
