The Emily Johnson slide collection at the University of Arkansas provided the majority of the images of fungi used on the web site, but additional images were provided by a number of other individuals. These included Peter Katsaros, Dan Guravich, Bill Roody, Eleanor Yarrow, Emily Johnson, and Henry H. Mashburn.

Virtually all of the other images (trees, habitats, etc.) on the web site were obtained during the course of visits to NCR parks by S. L. Stephenson.
