Accessioning and Exchange Policy
The University and Jepson Herbaria are constantly growing collections, reflecting the on-going growth in our knowledge of plant diversity and distribution. New acquisitions result primarily from 1) in-house staff and student collections, 2) standing exchange programs with other herbaria world-wide, 3) specimens sent as gift-for-identification to in-house researchers, and 4) gifts from a diversity of sources, especially non-academic professionals and native plant enthusiasts. The latter often serve as our most valued source of new records from under collected areas in the western United States.
In general, the Jepson Herbarium (JEPS) accessions only vascular plants from California, whereas the University Herbarium (UC) covers all plant groups world-wide. Gifts of California plants will be deposited in the Jepson Herbarium unless the donor specifies otherwise.
All exchange is through the University Herbarium. At present we are not soliciting new exchange programs, due to limitations in our capacity to generate and process outgoing material, consisting primarily of specimens from the western United States.
To minimize redundancy of specimens in the San Francisco Bay Area, we have a non-duplication policy with the California Academy of Sciences (CAS/DS). Exceptions are made for types and other particularly significant collections.
Because of limited specimen processing resources and storage capacity, specimens submitted for accessioning in the University of California at Berkeley herbaria should generally meet the criteria detailed as follows:
