Montana Master Naturalist


The goal of the Montana Master Naturalist Program is to increase natural history knowledge and promote awareness, understanding, and stewardship of Montana’s natural environment by developing a corps of well-informed citizens dedicated to conservation education and service within their communities. The core of this program is the Montana Master Naturalist Certification Course, which is approximately 45 hours of classroom and field time. The Montana Audubon Center is the home for this program in Billings and works with the Montana Natural History Center in Missoula to offer state-wide certification. Students who complete the course become certified as Montana Master Naturalists. To maintain their certification, Montana Master Naturalists are required to log 20 hours of volunteer service and participate in 8 hours of continuing education annually.


“The Master Naturalist class has truly enriched my life. I am more observant now than I ever was. How rewarding to know even more about the living things I share the environment with.” ~D.M., Billings Master Naturalist student 2018

This was an excellent course.  It left me wanting to learn even more, and gave me the resources to do so on my own.” ~M.H., Billings Master Naturalist student 2020

2023 Certification Courses

This course is designed for adults who want to deepen their knowledge of the natural world. We’ll explore everything from birds and insects to geology and plant ID. You’ll hone your naturalist skills as we practice journaling, animal tracking, and the art of observation.

We offer the course in two formats to fit your schedule:

  • An 8-month long course meeting two evenings a month from April – November with two Saturday field trips. This course structure will allow participants to learn about and observe the natural world across all the seasons with plenty of time for reflection and synthesis of new knowledge. We’ll cover a wide breadth of topics with the goal of giving you an essential foundation of skill and knowledge on which you can build.
  • A 5-day intensive course in June. Dates to be announced in April. To accommodate the compressed nature of the course we will focus on four main topics (identification of birds, insects, mammals and plants).

  • Assisting with any kind of natural history/biological survey (iNaturalist, eBird)
  • Participating in a Christmas Bird Count
  • Collecting monarch larval monitoring data
  • Monitoring water quality or macroinvertebrates
  • Collecting/interpreting biological data for any number of projects through SciStarter, Zooniverse, or other local or nationwide projects

Stewardship includes natural resource management activities. Examples include:

  • Removing invasive weeds
  • Helping develop a school forest management plan
  • Assisting with restoration (collecting native seeds, planting native species)
  • Improving trails to reduce erosion
  • Helping maintain a community native plant garden

Education includes the presentation and/or development of educational materials.  Examples include:

  • Assisting in teaching visitors about wildflowers at a nature center
  • Writing a Field Note or educational article for publication in a magazine or newsletter
  • Creating a brochure for a natural area
