Potomac Valley Master Naturalist Program
Our Potomac Valley Master Naturalist Program has proven to be one of our most popular adult programs. Each year, twenty participants are trained in a variety of natural history subjects including bird identification, soil science, general ecology, and aquatic studies. Once participants have completed coursework and volunteer service, they are “certified” to help with citizen science projects and educational programs across the state.


Nature Journaling
Joy Bridy leads these beloved workshops, where participants can explore nature through creativity. Whether you’ve been keeping journals for years, or a budding beginner, we welcome you to come out and put pencil to paper in the company of other enthusiasts.

Field Trips
PVAS regularly schedules a variety of field trips each month. Some trips are focused on birding; others involve exploration of sites and facilities of general natural history interest. Anyone who is interested is welcome to participate in any of our trips.

Monthly Programs
PVAS offers monthly programs that are free and open to the public. These presentations feature expert speakers on a variety of natural history and conservation topics.

Natural History Workshops
Each year during the spring, summer and fall, PVAS offers a series of Natural History Workshops. The workshops consist of three or more hours of instruction on a specific natural history topic.

This Race is for the Birds
The event includes two professionally timed trail races: a 5k and a 10k. There is also a 1-mile fun run for children.

Adult Birding Programs
PVAS has a very active Birding Committee that was formally established in 2011. The Committee organizes all of our birding field trips, sponsors an annual Birdathon, and is engaged in a variety of other projects and activities as well.
