The Minidoka District is separated from the rest of the forest by the Snake River Plain, also known as Idaho's potato belt; snowmelt from the forest provides a steady supply of water to the plain. The Minidoka District is a part of the Basin and Range Province, and while much of the vegetation here is similar to the northern part of the forest, the presence of Rocky Mountain juniper is notable as well as is the occasional cactus plant. In these pinyon-juniper woodlands trees also include singleleaf pinyon, Utah juniper, and curl-leaf mountain mahogany. Idaho's rarest plant, the Christ's Indian paintbrush, is endemic to on upper elevations of Mount Harrison in the Albion Mountains in the Minidoka District. Davis' springparsley is also endemic to the Albion Mountains. Additionally, the forest contains potential habitat for the threatened Ute lady's tresses.
