The Chico State Herbarium

Chico State Herbarium 120,000 Speciman - Lowell AhartChico State Herbarium 120,000 Speciman - Lowell Ahart
The Chico State Herbarium passed another minor milestone by accessioning its 120,000th specimen – see the number 120,000 stamped in the middle of the Herbarium logo on the lower left side of the sheet in the left photograph. This specimen is another fine example of the collecting and specimen mounting of Lowell Ahart – his collection number 21,434 from last summer.

Located in Holt Hall room 129, the Herbarium is the most complete repository of plant specimens from northeastern California. The emphasis is on the northern California flora, and includes a great number of rare, threatened, and endangered plant species. Established with specimens donated by the late Professor Vesta Holt in the 1950's, the herbarium now contains more than 107,000 dried and mounted plant specimens. The majority of samples are flowering plants, conifers, and ferns, but bryophytes, lichens, and especially slime molds, are also well represented. The herbarium is used extensively for identification of sensitive and other plant species by various agencies and individuals. Loans of herbarium specimens are made to any higher academic institutions who request them.

Facilities available to visitors to the herbarium include the use of high-quality dissecting scopes, a compound microscope, an extensive reference library, an internet-connected computer, an internet connection for personal computers, and, with suitable training, access to the collection of specimens.

Users of the herbarium facilities and collection are encouraged to make plant collections during their field excursions and donate them to the herbarium. This is how the collection grows and increases its utility and importance to the whole botanical community.

Making a donation to the
CSU Chico Herbarium has
never been easier!
