Join a state-wide volunteer network by becoming a Maryland Master Naturalist

How do I become a Maryland Master Naturalist?

Application to the Maryland Master Naturalist Program is made through individual Host Sites (see Volunteer Training Region links below). Candidates must be 18 years of age or older, have transportation to training classes/field trips and volunteer service activities, and be available to complete the 60-hour training as well as volunteer 40 hours per year. Applicants must show an interest in natural resources and be able to read, write and comprehend the information presented in the training sessions. Applicants must be able to interact with and communicate that information to the general public. The Master Naturalist trainee must pass a final exam in order to volunteer in the program.

Maryland Master Naturalist Program trainees are selected by the training program Host Site(s) as suitable volunteers based on their applications, references, and interviews. Once accepted into the program, there is a $250 fee due at the start of the training to cover the cost of materials. 

Individuals accepted into the Maryland Master Naturalist Program receive 52 hours of instruction, including hands-on activities and demonstrations, indoors and out. The course also includes at least 8 hours of a field trip or trips to a different site, for a total of 60 hours of instruction and field programming.

All classes and field trip(s) are taught by experts in the subject. The curriculum includes:

Introduction to Maryland Natural History
Flora and Fauna: Identification, Behavior and Taxonomy
Fundamental Ecological Principles
How Humans Affect the Landscape
The Science of Science
Teaching and Interpretation 

See the Master Naturalist Policies and Guidelines to learn more about training to become a Master Naturalist.

Training Regions of Maryland

For our training purposes, we divide Maryland into three physiographic regions. The areas differ in their geographic features, plants, and animals. Applicants should choose a training course in the region where they plan to do volunteer work as a Master Naturalist.

TRAININGS in the Coastal Plain Region

The Coastal Plain Region is the farthest to the east and includes all the low-lying areas from the shores of the bay to the Atlantic Ocean. Eastern Cecil, Kent, Queen Anne's, Caroline, Talbot, Dorchester, Wicomico, Somerset, Worcester, Anne Arundel, Prince George's, Calvert, Charles and St. Mary's Counties are all in our Coastal Plain Region, along with the eastern part of Baltimore City.
