Founded in 1958, the High Plains Herbarium at Chadron State College (CSCN) houses over 60,000 plant specimens and is the second largest collection in Nebraska. Historically our focus has been on the vascular flora of the Nebraska Panhandle, southwestern South Dakota and eastern Wyoming, with special emphasis on the Nebraska Pine Ridge escarpment and Sandhills. We also have a strong representation of material from the central Great Plains, particularly Nebraska and Kansas as well as the Rocky Mountains. In recent years we have expanded our holdings to include over 2000 bryophyte and nearly 1000 lichen specimens, mostly from the Nebraska Panhandle. The herbarium also houses the personal herbarium and library of plantsman Claude A. Barr and the personal papers of ethnobotanist George Morgan, in addition an extensive historic pharmaceutical collection.
