To maintain their certification, Master Naturalists are required to complete 20 hours of volunteer service and 8 hours of continuing education each calendar year.

The goal of volunteer service is to strengthen local communities by improving natural areas and educating people of all ages about Montana’s natural environment. Many communities and organizations rely on citizen volunteers. In fact, a short supply of dedicated and well-informed volunteers is often cited as a limiting factor for community-based conservation efforts. Our Montana Master Naturalists help fill that gap, sharing their knowledge, curiosity, and expertise, giving thousands of hours a year to their communities.

The goal of continuing education is to help Master Naturalists continue to increase their understanding of Montana’s ecosystems, flora, and fauna–and it’s a great way to meet other naturalists and scientists, too!

Recertification Deadline: January 1.

If you graduated in 2021, your deadline is Jan. 1st, 2023.

If you graduate in 2022, your deadline Jan. 1st., 2024.


Did you lapse and need to recertify? We now have two ways for you to regain your certification. You can either 1) take the Master Naturalist course again, or 2) complete 30 hours of volunteering, plus 12 hours of continuing education, in one year.  The continuing education must be provided by classes or field days, not lectures. If your hours lapsed due to COVID, please contact Christine Morris, cmorris [at] montananaturalist [dot] org.

Criteria for Montana Master Naturalist volunteer service

The activity needs to:

  • occur in Montana unless you live out of state
  • be sponsored by an organization
  • be unpaid

Each volunteer service activity may fit under one of these categories:  Citizen Science, Stewardship, Education, Organizational Support, Other.

Citizen Science involves volunteers assisting with scientific research.  These projects usually involve gathering data and returning it to researchers.  Examples include:

  • 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
  • Assisting with an environmental education program for a school group (Boy Scouts, Girl Scouts, 4H, church group, etc.

Organizational Support projects include working to ensure the functioning of any conservation/environmental organizations. Examples include:

  • Preparing mailings
  • Answering phones
  • Computer work
  • Organizing a digital library

Examples include:

  • Project WET, WILD, or Learning Tree training
  • Plant or animal identification course or presentation
  • Water quality monitoring training
  • Montana geology or climate course or presentation
  • Volunteer orientation for a nature center

  • Because we have some great documentary film festivals in Missoula and elsewhere in the state, we will allow up to two continuing education hours from watching a natural history-focused documentary film at a film festival, ideally focused on Montana (or at least the West), and even better if there’s a discussion forum afterwards!
