The team planning and managing the arboretum development project is composed mostly of volunteers but includes some township staff. Several volunteers have related professional experience and credentials such as certified arborist, master gardener, and landscape architect. Almost all of the volunteers have been through a two-year series of classes and assignments conducted by the state forester. Some of the staff have also studied under the state forester and each has experience in some aspect of the needed work.

2. Should the team seek more volunteers? If so, how should they supervise them? Where should they seek additional volunteers?
