ArbNet Arboretum Accreditation is valid for five years, after which you can renew your accreditation for no charge.

Before your five-year accreditation period has lapsed, ArbNet staff will proactively reach out to you several months in advance to notify you of your upcoming renewal due date. It is important that you always notify ArbNet staff of contact changes at your organization to prevent lapses in communication resulting in your accreditation expiration.

ArbNet will send you a personalized link to your application form that will be prepopulated with the information you submitted on your most recent application. The renewal form will then ask for any changes to your materials, staffing, or management practices that could affect whether you meet accreditation standards, or if your arboretum has advanced your practices and expanded institutional capacity, and whether you are eligible or interested in upgrading your accreditation to a higher level.
