During the volunteer sessions at the Hoover Herbarium, people can take part in any number of activities. One of our primary responsibilities is mounting new specimens. This involves taking dried and pressed plants and glueing them to paper. When we mount plants, we do it in such a way that those specimens will last for hundreds of years. Each specimen is a physical record of what plants occurred where and when. Without this valuable information we wouldn’t know when a species goes extinct, expands or contracts its range, or where species occur. After mounting, the specimens are databased and geo-referenced. Then they are filed into the main collection. We have over 80,000 specimens at the Hoover Herbarium. We are also working on a SLO Voucher Collection, which will contain one representative specimen for each species in the county. Volunteers look through our specimens and pick the one that should be added to the Voucher Collection. Additionally, we are actively working on our moss and lichen collections. Volunteers can choose what aspects of the work they would like to participate in. Any and everyone is welcome. The Hoover Herbarium is located on the 3rd floor of the Fisher Science Building (33) in rooms 352 and 359.
