Project Team

The Portland Heritage Tree Podcasts were created by Caitlin Tholen, Joshua Justice and Ryan Wisnor as part of a Portland State University course on Portland’s Heritage Tree program. These podcasts explore a few of the many trees within the program as well as a few trees that are not officially designated. On this site, you’ll find not only the podcasts, but credits and further reading on the trees. A special thanks to Bruce Rash of KPSU for his assistance in recording these podcasts.
