With Oregon Master Naturalist Online, learn about natural history, ecology and natural resource management practices by studying many aspects of Oregon’s environment.

The Oregon Master Naturalist Program provides an opportunity to learn about natural resources through the study of scientifically sound information:

  • The natural history of plants
  • Animals
  • Habitats
  • Geology
  • The history and processes of landscape change
  • And the most relevant topics in present-day sustainable natural resource management

As a part of the program, you get to volunteer for natural resources programs, agencies, organizations, and other groups in their communities.

This research-based course is offered each year in January and September.


The Mission of the Oregon Master Naturalist Program is to develop a statewide corps of knowledgeable, skilled, and dedicated volunteers who enrich their communities and enhance public awareness of Oregon’s natural resources through conservation education, scientific inquiry, and stewardship activities.

"For me the pace and amount of material presented or made available for additional reading was just right.  Jason was on top of things when there was a computer glitch of any kind and promptly answered questions.   Overall, I am very satisfied with the course."
William Buckley, OSU ChemE 1967 
"I have already used the watershed portion of the course in my fellowship to help prepare for a presentation. Thanks to Jason and his organization and insightful comments."
Wendy Doerner
"Overall a lot of really great information presented in a way that made it easy to understand. Online courses were straightforward and not overly technical, with avenues to get more technical if interested. In-person courses were well organized and very informative; the speakers for each were excellent."
Diane Lang Oregon Master Naturalist Course
"I enjoyed the course materials immensely, especially all the added graphics, videos, and interesting additional online resources. I can only compliment the materials and pace of the course."

The course occurs over a 12-week period. The first eight weeks contain weekly modules, a final exam is available starting in week nine, and the last three weeks are designated as a catch-up period where no new content is presented. Participants should expect to spend roughly 6 hours each week on coursework.

The online course is designed to be taken first, as it is the core and introductory curriculum. Because there is no policy that says you have to take the classes in any specific order, you could take the ecoregion specialization course first. There is no time limit between taking the online course and the Ecoregion course.
