Sax-Zim Bog Biome

The Sax-Zim Bog might be most familiar to you as a world-renowned bird watching location during the winter months. This is certainly true, but this vast set of ecosystems is incredibly biodiverse! With bogs, upland conifer forests, mixed forest, small and medium sized lakes, two major river systems, and an interesting geological history, the Sax-Zim Bog offers a lot for budding naturalists to enjoy during any season.

This training will take place right in the heart of the Sax-Zim Bog at the newly constructed Lois King Education Center at the Friends of Sax-Zim Bog Welcome Center. We will hope to spend a majority of our time together outdoors experiencing everything that this location has to offer in the context of Master Naturalist Training! There is no better way to learn about a biome than to get out and experience it firsthand and early fall can be great time to visit and learn about the Northwoods.

Participants should expect to be outside in a wide range of environmental conditions (light rain, warm temps, muddy conditions, etc). Expect some hiking to be done, primarily along gravel roads, level boardwalks, with mostly level terrain through the duration of the course. Restrooms and our meeting location are both accessible locations. With further questions about expectations for hiking, accessibility notes, or weather conditions prior to registration, contact course instructor FOSZB Head Naturalist Clinton Dexter-Nienhaus.

  • The course will run from 9 to 6:30 p.m. Monday through Friday from August 21 and ending August 25, 2023.

About the North Woods, Great Lakes course

This core course's training is tailored to Minnesota’s unique Laurentian Mixed Forest biome. The largest biome of the state, it covers over 23 million acres of northeast Minnesota. The region contains a multitude of landscapes, including swampland, bogs, vast forests, lakes and exposed bedrock.

North Woods, Great Lakes covers topics of geology, glaciers, water, wildlife, humans, ecology, and botany using a variety of teaching techniques, ranging from lectures, classroom discussions, field trips, fieldwork, small group work and readings.

Participants must complete the full 40 hours of training to become a certified Minnesota Master Naturalist Volunteer.

Each participant must complete a group capstone project. Participants will choose a capstone that they can complete before finishing the course.
