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 . No other international program of accreditation exists that is specific to arboreta. Any arboretum or public garden with a substantial focus on woody plants may apply. Accreditation is based on self-assessment and documentation of an arboretum’s level of achievement of accreditation standards, including planning, governance, number of species, staff or volunteer support, education and public programming, and tree science research and conservation. The entire program is free of charge.
