The UCSC Herbarium houses approximately 10,000 vascular plants, algae, lichens, and bryophytes. The collection focuses primarily on specimens from within Santa Cruz County and the University of California Reserves but also contains collections from the rest of California and from other states and countries. The collection archives research and publication voucher specimens and is also a student education resource. Notable collections include those of R. Morgan (1969-2017), David Styer (Fort Ord National Monument, 2006-present), and Dylan Neubauer.
