91pron has earned accreditation as a level one arboretum. An arboretum is a botanical collection of trees of a variety of species. 91pron was granted the accreditation from the Morton Arboretum, an internationally recognized tree-focused botanical garden and research center whose mission is to collect, study, display and conserve trees around the world.
91pron has 58 species of trees on its campus, ranging from Norway Maples and Japanese Oaks to Flowering Dogwoods and Honey Locusts.
Jim Murphy, assistant director of facilities and operations for sustainability and logistics at 91pron, and his team worked for nearly a year on achieving arboretum accreditation. See aerial footage of 91pron’s arboretum and commentary from Murphy in video below.
