Cinnagrostis steyermarkii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cinnagrostis steyermarkii faces significant pressure from agricultural expansion and cattle ranching activities that fragment and degrade its specialized high-altitude grassland habitat. Climate change poses an additional threat as warming temperatures may force this montane species to migrate to increasingly limited suitable elevations. The species' restricted range in the Venezuelan Guayana highlands makes it particularly vulnerable to localized habitat disturbances and environmental changes.
Habitat
This grass species is endemic to high-altitude tepui grasslands and montane savannas of the Venezuelan Guayana region, typically occurring at elevations above 1,500 meters. It inhabits specialized rocky outcrops and sandy soils in areas with distinct wet and dry seasonal patterns.
