n introduction to the mosses of cold-temperate and boreal forests, emphasizing growth form, field characters, ecological patterns, and geography. Indoor sessions to learn the common species, field trips to locate them in the woods; lots of looking, comparing, drawing, discussing; an hour or two of stories about mosses and forests and the planet; a little microscopy to show you what the next steps look like.

Course Objective

To start at the beginning, go slowly, and enjoy ourselves.

About the Instructor(s)

Jerry Jenkins, from White Creek, New York, was trained in philosophy and mathematics, and has done botanical work 54 years. He has free-lanced in botany and ecology, worked as a researcher for the Wildlife Conservation Society, and currently produces books and imagery for the Northern Forest Atlas Project. He has written books on Vermont geography, acid rain, climate change, conservation easements, Adirondack geography, and three photographic guides (Woody PlantsSedges, Mosses) and accompanying digital atlases for the Atlas Project. We will use the moss guide and digital atlas in the course. He is currently working on a full-length field guide to woody plants and a book on ecological patterns.
Sue Williams, from Rowe, Massachusetts, has worked on mosses for thirty years. She began with Howard Crum at Eagle Hill, and since then has studied and collected them all over the Northeast east. Her ability to find and identify things in the field is legendary: the rest of us say “If Sue can’t find it, it’s not there.” About ten years ago she began drawing mosses and writing down the characters she uses to recognize them. She has now put them together in a book, the Ecological Guide to Mosses of New England, which will be published in 2021. We will use preprint copies in the course.
Jerry and Sue have studied and taught mosses together, all over the northeast, for 25 years. The Atlas moss guide, moss maps, digital atlas, and our field-based teaching methods are products of our collaboration.

Required Materials and Recommended Reading

We will use a pdf on Moss Basics that we will supply, Mosses of the Northern Forest (J.J., Cornell University Press, 2020), the Ecological Guide to Mosses of New England (preprints) by S.W., and the Digital Atlas of Northern Forest Mosses (JJ., Northern Forest Atlas, 2020). We will have copies of Mosses of the Northern Forest for use or purchase. The digital atlas is available as a free download from our  website, The Ecological Guide should be out in 2021.


Meals are not provided in our 2021 season due to ongoing COVID-19 concerns.
