Course Description

The MMNP course is a year-long, in-depth exploration of natural history. Following graduation, Maine Master Naturalists are ready to introduce others to Maine’s natural world.

Next Course

In light of uncertainty related to the pandemic, we regret that the 2021 course, scheduled for Wells Reserve, will be postponed until 2022. Please check back in summer 2021 for more information about the next course. 

Time Frame

The course runs from January through October. Typically, classes occur twice a month: one weekday evening and one Saturday of class and field work.


The Maine Master Naturalist course moves to a new location each year with the long-term goal of making the training accessible throughout Maine. Courses have been offered in Augusta, Belfast, Blue Hill, Bridgton, Ellsworth, Falmouth, Holden, Lewiston, MDI, South Paris, Waterville and Wiscasset. While the program’s goal is to serve more areas in Maine, the volunteer instructors and organizers are limited in how far they can travel to get to class.  Anyone in conceivable driving distance of a course should seize the opportunity to apply.

The board is now working on future courses and will post locations here as soon as plans are in place. The 2020 class is underway in Waterville. In January 2022, a course will begin at Wells Reserve at Laudholm. The application will be available here on September 1, 2021. Applications will close October 15, with admission decisions released by November 15.

Applications are not being accepted at this time.

Planning, Instruction, and Support

MMNP is an all-volunteer organization.

  • Board members plan the courses, establish the curriculum, and oversee all of the course operations.
  • Course coordinators handle all the details of the course including liaising between the course location and the board, arranging for instructors, and supporting mentors and students.
  • Instructors give their time generously to teach the students and to support the mission of the organization.  Some instructors are members of the MMNP community while others are outside experts.
  • Mentors assist students during the course. All are Maine Master Naturalists who have previously completed the course.


The MMNP core curriculum covers the following topics, with a strong emphasis on Maine species and habitats.

  • Amphibians and reptiles: taxonomy, ecology, habitat, identification
  • Birds: physiology, evolution, behavior, species identification
  • Ferns: life cycle, collections, identification
  • Fungi: overview, structure, life cycle, identification
  • Insects: taxonomy, observation, collections
  • Lichens: overview, structure, life cycle, identification
  • Mammals: tracking, skull and scat identification
  • Trees: leaves, buds, bark, collections, identification
  • Wildflowers and shrubs: families, fruiting structures, winter botany, identification
  • Ecological Principles: understanding ecosystems, relationships among species, and flow of energy
  • Geology: basic principles, geologic history of Maine, site study
  • Natural communities: landscape-level patterns and relationships among species
  • Nature journaling: sketching and recording observations and reflections
  • Pedagogy: teaching others
  • Phenology: keeping track of seasonal changes during the course
  • Vernal Pools: ecological function, indicator species, regulations
  • Watershed ecology: ecology of lakes and rivers


The fee is set each year, based on the costs of facilities and books and other materials. The most recent course fee was $650. Instructors, coordinators, mentors, and board members are not paid, and the fee is set to cover program costs.

Time Commitment

Total time in class is about 100 hours. Students generally spend a minimum of 200 hours outside of class completing homework assignments and at least 20 hours on a capstone project. Because each session covers a new topic, students must be able to attend every class.


Students receive a hand lens, field guides, identification keys, and numerous handouts. Students also print out materials themselves from course links.


Homework: Students submit homework related to the various areas of study. Assignments include collecting specimens, practicing with identification keys, drawing, and responding to readings. (Note: sketching is assigned solely to develop skills in observation, with artistic merit as an occasional fortunate byproduct.)

Quizzes: Students take a short quiz at the beginning of each class. Quiz questions flow directly from a study guide provided for each topic.

Delimited site: Students select a “delimited site,” a specific spot to visit at least once a week throughout the course to make observations and witness changes in nature.

Nature Journal: Students keep a nature journal, which mentors review monthly. The journal includes observations and sketches from the delimited site.

Phenology observations: Students record seasonal natural phenomena, especially changes in animal and plant life. 

Public walks: To gain experience as teaching naturalists, students are required to observe and then serve as assistant leaders in public nature walks outside the course.

Capstone: The capstone is the final project in the course. Each student spends a minimum of 20 hours researching a particular aspect of natural history in Maine and developing an educational program, field experience, trail guide, or similar product that others can use. Mentors can help in guiding the choice of the project. Students present their capstones to the class at the end of the course (a fun learning opportunity for all). Click below for some examples of capstones:

Key to 20 common species of woody fungi in Maine.

Self-guided natural history map for a section of the West Gardiner Nature Trail.

Set of field lessons on the natural history of the Lewiston-Auburn area.

Guide to using bark to identify tree species with examples on a covered bridge in Bridgton.

Series of activities for instructors focusing on the night environment.

Illustrated children’s book: “Lila Liverwort Explores the Forest”.

Pocket guide to stone walls.

Hands-on demonstration and series of activities to teach the geology of the Cathance River.

Winter guide to observing insects.

Set of lessons on vernal pools and a field trip to Hidden Valley Nature Center for 7th graders.

Attendance and Make-Up

Because each class covers a new topic, students must arrange their schedules to attend every session of the course and must reserve the make-up dates set in case of snow days.
Before applying, applicants should check the schedule carefully. The course application requires that students affirm that they do not have conflicts with class and makeup dates.
If a student must miss a class due to an unanticipated emergency, the student’s graduation may be deferred until the student can make up the class in the following year’s course.

Volunteer Teaching Requirement

In keeping with MMNP’s mission, in the year following graduation, Master Naturalists are required to volunteer 40 hours teaching others, reporting their time back to the organization. After that, Master Naturalists are expected to volunteer at least 20 hours per year. The credential of “Master Naturalist” opens the door for graduates to share their knowledge with a wide variety of people in many settings.
Students will have chances throughout the course to engage in experiential learning and practice teaching so that they have the confidence to engage with others following graduation.

Program fit

The Maine Master Naturalist Program exists to train amateur naturalist volunteers to teach the general public about Maine’s natural world. This program is not a good fit for everyone.

  • If you’re looking for skills for employment as a naturalist, you need a college degree.
  • If you know you will never be comfortable volunteering as an instructor or leader, this course is not for you.
  • If you already have extensive natural history knowledge, training, and skills, you may find some of the material too elementary and are probably already qualified to volunteer to share your knowledge with others. .
  • If you are too busy to do homework assignments and to practice outside, the course will not benefit you, because the classes are only the introduction. The deep learning happens on your own time.

Frequently Asked Questions

No. The program’s mission is to train volunteers who then go on to help others learn. It’s wonderful when anyone wants to learn more about nature, however MMNP doesn’t have enough teachers or time to offer the course solely for a student’s self-enrichment.

No. There are typically more applicants than the course can accommodate.

No. Space is limited and demand is high. MMNP accepts only individuals who can make a full commitment to the course and volunteering afterwards.

MMNP does offer CEUs for the program. Once you’ve been accepted, ask the Course Coordinator for details.

Course locations are limited by how far the volunteer instructors, mentors, and coordinators can reasonably travel to the course. MMNP tries to select course locations in somewhat centralized population centers that have suitable facilities available for a reasonable cost. If you can conceivably get to a course location, you should apply. MMNP may not be able to offer a course closer to you.

Absolutely. Technology plays an important part in the MMNP program. Students receive course materials using Google Drive and communicate frequently via email. Students print many of their own course materials for each class. Access to a computer, the internet and a printer is essential for every MMNP student.

Yes. Students are required to collect and preserve specimens from trees, ferns, wildflowers, and insects (found-dead insects are acceptable). These collections aid the students’ understanding of the subject matter and are useful when teaching others.

If a student withdraws before the first class, the refund is the tuition amount less $20.00. If a student withdraws prior to the third class, the refund is 20% of tuition. Thereafter, no refund will be issued.

MMNP requires payment in full upon enrollment, but in exceptional circumstances MMNP can offer a limited payment plan.

MMNP is not able to offer scholarships at this point. Some accepted students have found organizations to sponsor them. A good example is a land trust that the student already volunteers with that will benefit from a Master Naturalist’s teaching.

If an organization or individual is interested in sponsoring a scholarship, we would be delighted to set one up. Please get in touch through the Contact Us page.

Yes! MMNP gratefully accepts contributions, which are tax deductible. Please get in touch through the Contact Us page.
