Ecoregions

Northern Basin and Range

The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats.

Key Habitats

Aspen Woodlands

Aspen (Populus tremuloides) woodlands are woodland and/or forest communities dominated by aspen trees with a forb, grass, and/or shrub understory. Aspen woodlands also occur within conifer forests.
