The Quercus collection at Starhill Forest has been documented in the form of a digital herbarium. The images of the oaks in this database are of living trees within the collection (unless noted). Each entry has two photos:
1. A photo of fresh foliage with a scale bar against a black background
2. A photo of the entire tree with a two-meter scale bar

Some traditional herbarium specimen collected at the Arboretum are kept on file in the collection at Illinois College. They can be viewed upon request. There is not a pressed specimen for each of the plants in this digital collection. Requests for plant material, to view trees in the collection, or simply for more information, contact Alana McKean or Guy Sternberg.
