The museum's collections include vascular plants, invertebrates and vertebrates from the American West, Central and South America, and from throughout the world. It is open to visitors by appointment.
  
  The Museum was said in 1997 to hold the largest collection of frozen tissue samples (85,000) in the western hemisphere and has assisted in the study of emerging zoonotic pathogens such as the Hantavirus and the Lassa virus.
