How will cheatgrass respond to projected changes in future climate?

Increasing temperatures and reduced summer precipitation are projected to favor expansion of cheatgrass (Bromus tectorum) at higher elevations.  The greater the change in summer conditions, the greater the expected shift in cheatgrass (Bradley et al. 2016).  Although cheatgrass will probably decline at lower elevations, red brome (B. rubens) already present throughout the Great Basin will possibly replace cheatgrass.
