Cinnagrostis hirta
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cinnagrostis hirta faces significant pressure from agricultural expansion and livestock grazing in its native South American grassland habitats. Urban development and infrastructure projects have fragmented remaining populations, while altered fire regimes and invasive plant species further degrade the specialized grassland ecosystems this species requires. Climate change poses an additional long-term threat through shifting precipitation patterns that could alter the delicate moisture balance of its preferred habitats.
Habitat
Cinnagrostis hirta inhabits temperate grasslands and open savannas of South America, typically occurring in well-drained soils at moderate elevations. The species shows preference for areas with seasonal moisture variation and is often found in transitional zones between grassland and shrubland ecosystems.
