The Curlew National Grassland comprises 47,000 acres of public land. It was originally established to improve the soils and vegetation. Historically the Curlew Grassland, in Southeastern Idaho, was inhabited by the Bannock and Shoshone Indian Tribes before the settlement of the pioneers. In the late 1800s and early 1900s, the Curlew Valley had a ranch on every 160 acres. When drought years of the late 20s and early 30s came, the land wouldn't support these homesteads. Many fields were badly eroded.
