Our 11-acre arboretum is located on JJC's 368-acre Main Campus, between the entrance and exit roads, adjacent to Houbolt Road at the main gate. It is a place where woody plants, trees, shrubs, and vines are grown for exhibition and study.
The college arboretum concept was originated by Dr. William M. Zales in 1975 as part of a master campus use plan. Upon Dr. Zales's retirement in 1999, the arboretum was renamed in his honor to recognize his contributions. The master plan includes development of nature trails, restoration of native ecosystems, such as the prairie, fen, various stages of forest successional types, soil conservation measures for the agricultural crop land, and management plans for the campus lake.
These continuing projects are managed by the JJC Natural Areas Committee, the Grounds Advisory Committee, and the college's building and grounds staff. In the spring of 2004, the JJC Foundation and Alumni Relations (The Office of Institutional Advancement) and the Natural Area Committee launched a new project called Trees for Tomorrow to raise funds for the continued development and maintenance of the arboretum.
Funds from the Friends of the Arboretum will be used to purchase and plant trees for the arboretum. These outdoor facilities are used and enjoyed by students both in and out of the classroom, as well as by faculty, staff and community members from throughout the district.
Trees for Tomorrow
Joliet Junior College invites you to become a member of Friends of the Arboretum, which works to improve and diversify the 11 acre arboretum at Joliet Junior College's Main Campus.
The Dr. William M. Zales Arboretum is intended to serve JJC students, faculty, staff, and the community as a unique educational resource. Dr. Zales retired from JJC in 1999 after having served the college for over three decades. The arboretum was named in his honor.
Please help us make JJC's arboretum the living laboratory Dr. Zales intended it to be. We would like to increase the number and diversity of plantings to include more than 200 species belonging to more than 100 genera in approximately 50 families. Our vision is to create a park-like setting with winding footpaths, benches, and educational information about the native and naturalized woody plants growing in the arboretum.
Your tax-deductible donation will allow you to become a member of Friends of the Arboretum and will enable the college to make the needed acquisitions to develop and maintain the arboretum well into the future. Trees will be added to the arboretum in the spring and fall seasons of each year.
To make a contribution, download a donation form and mail it with a check payable to the JJC Foundation.
