About the Arboretum

Cora Hartshorn Arboretum and Bird Sanctuary is a non-profit organization located in Short Hills, New Jersey. The property was willed to Millburn Township in 1958. In 1961 an Arboretum Association was formed to work with the Township in order to protect the area. The Cora Hartshorn Arboretum includes 16.45 acres of woodlands, 3 miles of trails, and a diversity of floral and fauna species. Our master gardener and woodland volunteers take great care to ensure that plant species indigenous to New Jersey are predominant. The Cora Hartshorn Arboretum provides many educational opportunities from school field trips, scout programs, family programs, adult workshops, summer camp, and more.
