YM - Yosemite National Park (YM)

Yosemite National Park Herbarium is a significant regional collection, with 8,000 specimens, dating from the early part of the 20th century to the present with the bulk of specimens dating from the 1920s to the 1960s. This is an actively growing herbarium, with over 3,000 vascular plant specimens added in the last ten years. The herbarium is a valuable component of the park's museum collections and is an essential tool for resource management: fire management, exotics programs, and vegetation management. It is also a valuable source of information to the scientific community about Yosemite's complex flora. Access to the collections is granted to researchers by advance appointment.
