Oregon State University Extension Master Naturalist training is delivered in two parts. You must complete both parts.

Part 1: The Oregon Master Naturalist Online Course covers a broad range of natural history and natural resources conservation topics, and becomes the foundation for further training and lifelong learning. The material is delivered entirely online through an interactive website. Learn more by clicking here.

Part 2:  Ecoregion field courses offer you a chance to experience a more indepth study of a growing list of field courses we offer. These courses build upon the Online Course, are taught in the field by leading experts, and focus on one of Oregon's ecologically distinct regions. A typical course contains 6-8 all day classes.
