EPA Level III Ecoregion
Northwestern Great Plains
720 native plants for the Northwestern Great Plains ecoregion (Billings area).
The Northwestern Great Plains roll across eastern Montana and Wyoming into the western Dakotas, taking in Billings, Rapid City, Casper, and Gillette. This is semi-arid shortgrass and sagebrush country, with hard winters, wide temperature swings, and long dry spells broken by sudden storms. Natives like blue giant-hyssop, golden prairie-clover, and plains beebalm are deep-rooted enough to ride out a dry summer with no irrigation at all.
Conditions: Clay and sandy soils over shale, 12–18 inches of precipitation, cold windy winters, hot dry summers punctuated by sudden storms.
Cities and areas: Billings, Rapid City, Casper, Gillette, Miles City, Dickinson.
