May 4, 2021 (MITCHELLVILLE, Md.) — The 125-acre campus of Collington Life Plan Community, a Kendal Affiliate in Mitchellville, Maryland, has been awarded Level One Accreditation as an arboretum by the ArbNet Arboretum Accreditation Program. Collington earned the accreditation for meeting ArbNet’s set of professional practice standards for arboreta and botanic gardens. The ArbNet Arboretum Accreditation Program is the only global initiative to officially recognize arboreta at various levels of development, capacity and professionalism.

Level One Accreditation aligns with Collington’s goal of labeling all trees within the arboretum and adding more walking paths. Plans for the arboretum also include hosting field trips for local students and youth groups, and tours for members of the community.

In addition to the Level One Accreditation, the Collington campus is now recognized as an accredited arboretum in the Morton Register of Arboreta, a database of the world’s arboreta and gardens dedicated to woody plants.

Collington’s campus provides the senior living community’s residents with a scenic environment for exercise and to find peace and relaxation in nature. Community members may walk through the campus’s grounds and observe more than 100 different species and varieties of trees.

“We at Collington are excited to receive this accreditation and for the prospect of further improving the arboretum through this recognition,” said Anne Gillespie, Collington’s CEO. “We hope to offer our residents new spaces to be outdoors and enjoy nature, and plan to expand the arboretum to welcome more members of the Mitchellville community. We deeply value the serenity that can be found on Collington’s campus, especially during these stressful times.”
