Recognition in this program is a way to help convey the Scott Arboretum was established as a living museum, so we strive to and are expected to uphold professional standards and best practices in maintaining a curated ornamental plant collection in keeping with the Arboretum's mission, while residing on a college campus. It also will help convey we are not a typical college campus, given our collections of ornamental plants and educational programs have been developed to serve the public at large, not just beautify the college, and have been made possible by a variety of restricted endowment funds given solely for this purpose. Achieving accreditation is also a great way to convey to volunteers and donors we are worthy of their support and it will help us attract and retain talented staff members.

Becoming an Internationally Accredited Arboretum Level II shines a light on the environmental assets that the Town of Greenwich has and the historic significance of our community forest which includes both public and private land. Greenwich has over 100 trees listed in the Connecticut Notable Tree Project which includes CT's largest and most historic trees. With this richness of historic forest resources the GTC encourages our community to preserve our natural assets, practice stewardship of resources and to plant trees that future generations can enjoy.

Lillys at Ghent University
Accreditation by ArbNet is important for our garden for at least two reasons. First, this means an independent qualitative evaluation of our arboretum and garden, useful in our communication with both the general and more specialized public. Second, thanks to ArbNet we are able to contact a community of high-quality arboreta, useful for many possible reasons, from information on novel invasive species to exchanging specimens.
