The Ahart Herbarium is open to the public!
Current hours are Fridays 9:00 am to 5:00 pm.
Visitors accessing campus facilities must comply with the CSU Chico vaccination policy.
The Ahart Herbarium allows scientists, students, state agencies, and visitors to see and examine more than 115,300 North State plants, dating from the pre-1930s to today. This living laboratory and historical archive helps us study regional plants, identify rare species, and recover genetic information—it is a critical resource as our changing climate rapidly reshapes local ecosystems.
