This chapter describes the tall volcanoes and extensive lava flows that characterize the Northeastern Plateaus bioregion. This region represents California’s portion of the Great Basin. There are four basic fire weather patterns that can significantly affect fire behavior and natural ignitions in northeastern California during the May-to-October fire season. These are: the pre-frontal winds, lightning with low precipitation, moist monsoon, and strong subsidence/low relative humidity patterns. Additionally, the fire responses of important species and fire regime-plant community interactions in the sagebrush steppe, the lower-montane zone, the mid-montane zone, the upper montane zone, the subalpine zone, and the non-zonal vegetation are outlined. Changes to fire regimes have caused changes in plant community composition and structure, and wildlife habitat in many plant communities. Fire continues to be an important ecological process throughout the Northeastern Plateaus bioregion but its role has greatly changed.
