Vouchering is the process of preparing materials for a dried specimen sheet for an herbarium. Usually a voucher is a pressed, dried, plant specimen that includes characters necessary for identification and a label detailing where and when it was collected. These specimens are mounted onto acid free paper and can last hundreds of years when protected from insect and environmental damage. Vouchering is an ongoing process; vouchers are often made by graduate student assistants and filed in either the UC or Jepson Herbaria on campus.
This work is proceeding in the context of preparing a customized instance of CollectionSpace for the UC Botanical Garden. Much of the work is being done by students in a class on campus.
