While 2022 classes will be held mostly online, we will have several small-group, socially-distant, masked, in-person experiences—nature walks, field trips, meet-ups to see Master Naturalist Projects and places to volunteer.  Following health guidelines, we plan to offer ways to get to know you and for you to get to know our wonderful members.

Learn. Volunteer. Repeat.
