An urban oasis that is a botanical collection serving as a resource for research, education and the region's agricultural heritage that draws the community, including students and faculty, to become inspired to support its mission.

Arboretum Accreditation Program

ArbNet created its Arboretum Accreditation Program to establish and share a widely recognized set of industry standards for the purpose of unifying the arboretum community. The program includes four levels of accreditation recognizing arboreta at various degrees of development, capacity and professionalism.

In 2017, the Fullerton Arboretum achieved ArbNet’s Level IV accreditation. We became one of three arboreta in the state of California and one of 28 arboreta in the world to achieve this level of accreditation. As part of California State University, Fullerton, the Fullerton Arboretum collaborates on research with faculty, engages with other institutions on conservation projects and has an extensive tree collection with an associated database. Our nursery helps to propagate, conserve and safeguard our collections and other threatened plants. The Fullerton Arboretum’s living collection is home to many important plants, including rare, threatened and endangered species, specimens collected from the wild and cultivars of historical significance, including our nationally recognized citrus collection.



The Joint Powers Agreement ended December 3, 2020, making the Fullerton Arboretum a fully integrated department within the self-support division of Extension and International Programs at CSUF.
