Herbarium

The Yosemite Museum herbarium has significant regional holdings, with 8,000 specimens dating from the early part of the 20th century to the present. While most of the collections date from the 1920s to 1960s, it is an actively growing collection 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. Online access is available to the museum's herbarium through of the Consortium of California Herbaria (choose "YM (Yosemite N.P. herbarium)" as the source). Access is granted to researchers by advance appointment only. Contact the park's registrar for details.

Cars and campers in a meadow in Yosemite Valley.

Unrestricted camping is no longer allowed in Yosemite Valley because of damage it causes. The placement of campgrounds and campsites has changed over the past 75 years in response to a growing understanding of river dynamics, geologic hazards, and the park's natural and cultural resources.
