Abstract
Northeastern California landscape is a mixture of vast arid basins and uplands, and forested mountain ranges interspersed with both fresh water and alkaline wetlands. The entire bioregion is significantly influenced by the rain shadow effect of the Cascade Range to the west. Three ecological unit subsections are treated in this chapter: (1) Modoc Plateau Section (M261G), (2) northwestern Basin and Range Section (342B), and (3) extreme northern portion of the Mono Section (341Dk). The Cascade Range defines the western edge of the Modoc Plateau, and the Sierra Nevada defines the western boundary for the southern portion of the northwestern Basin and Range and Mono Sections. There is no one overriding feature that cleanly depicts this bioregion to the north and east as the political borders of the states of Oregon and Nevada, respectively, define the boundaries.
