Overview

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

Prairie Koeler's Grass faces severe threats from habitat conversion of native grasslands to agriculture and urban development, which has dramatically reduced available prairie ecosystems. Invasive species competition and altered fire regimes further degrade remaining habitat quality, while climate change threatens to shift suitable growing conditions beyond the species' current range.

Threat summary

Habitat

Native prairie grasslands, dry meadows, and open slopes with well-drained soils, typically in areas with natural or managed fire cycles. Also found in disturbed grassland edges and restored prairie sites at various elevations.
