FIRE ECOLOGY OR ADAPTATIONS:

Poverty oatgrass has adapted to fire by tillering and establishing from seed after top-kill [32,34,42].

Fire regimes for plant communities and ecosystems in which poverty oatgrass occurs are summarized below. For further information regarding fire regimes and fire ecology of communities and ecosystems where poverty oatgrass is found, see the "Fire Ecology and Adaptations" section of the FEIS summary for the plant community or ecosystem dominants listed below.
