Great Basin - Ecology

Ecology

Although mostly within the North American Desert ecoregion, portions of the Great Basin extend into the Forested Mountain and Mediterranean California ecoregions. The semi-arid areas of the Forested Mountain ecoregion include the White Mountains and Inyo Mountains. Extending north of the 42nd parallel north, the Northern Basin and Range (ecoregion) has its southern border at the highest shoreline of the Pleistocene Lake Bonneville. The south edge of the Central Basin and Range ecoregion is in Nevada, north of the south edge of the Great Basin section.

In phytogeography, the Great Basin is within the Great Basin Floristic Province of the Madrean Region in southwestern North America, part of the Holarctic Kingdom of the northern Western Hemisphere.
