The function of the Armstrong Arboretum can be divided into four areas: teaching, conservation, community outreach, and recreation.
The Arboretum provides an outdoor laboratory for use by faculty and students in Botany, Biology, Environmental Studies, Photography, Art, and other departments.
The Arboretum functions as a sanctuary for the preservation and conservation of plants. With collections of native and exotic flora, the Arboretum provides a model for environmentally sound urban landscape management.
The Arboretum allows the university to provide botanical and horticultural information to the community. Educational opportunities will be provided in the form of workshops, demonstrations, and tours. Booklets, maps, and plant guides allow the public to explore the Arboretum on their own.
The Arboretum provides a place where people of the University and the community may enjoy passive recreation in a beautiful setting. By walking through the collections or enjoying a stop on one of the many benches, visitors can renew themselves through contact with the natural world.
