This small herbarium consists primarily of specimens from south-central Nevada collected on federally controlled lands focusing on the Nevada National Security Site. There are just under 8,000 specimens collected primarily from 1960-1990. Dr. Janice Beatley was the originator of the collection and several Botanists have contributed records over the past 50 years. The U.S. Department of Energy provides support for maintaining the collection to assist with environmental work at the Nevada National Security Site.
