Since 1988 the Arboretum has been an official part of the college, while retaining much of its participatory character and relying heavily on volunteer contributions from within and outside the college to fund its work projects, notably students and faculty in Environmental Studies courses and, since 2001, by the Arboretum Manager, Joe Clements.
