Stephenson County Master Gardeners

Arbor Advocates

The  Arbor Advocates invite you to view the Don Opel Arboretum on the campus of Highland Community College. You are invited to enjoy it and the 68 trees and shrubs on this tree walk over and over again.

A group of the Stephenson County Master Gardeners, the Arbor Advocates, is working toward mapping and identifying all the trees included in the arboretum, as well as making the information available to the public online and in a new quality brochure.  The members of Arbor Advocates are currently focusing on the 68 trees and shrubs featured in the tree walk and are hoping to have that information available on the Extension website within a year.  The purpose of this group is to not only welcome the public to enjoy and appreciate the resources provided by the arboretum, but also to give people information about the trees and shrubs they might choose for their own yards and properties.

Come in spring to see the blossoms and buds emerge and experience the color of the awakening landscape. Stroll through the campus during summer to relax on one of the many benches placed conveniently under shade trees. In autumn the trees put on their final show of spectacular color – you won’t want to miss that. Return in winter to witness the interesting branch structure and bark details.


As with any natural setting we ask only that you take out with you whatever you bring in and that the trees and shrubs remain undisturbed. Enjoy!
