Moss Identification Workshop
Led by Joe Walewski author and naturalist from Wolf Ridge!
Saturday September 19 from 1-4pm at Sax-Zim Bog Welcome Center.

Become a “Micro-forest Explorer”
Join Joe Walewski, Wolf Ridge Naturalist and author of Mosses and Liverworts of the North Woods, for a deep dive into the bryosphere – the rich, hidden world right beneath our boots.
To most people, moss looks like simple green fuzz. But if you slow down and look closer, you discover an intricate micro-forest teeming with life. This three-hour, beginner-friendly workshop focuses on the ecology of these mini-ecosystems, using the diverse habitats of the Sax-Zim Bog area as our classroom.
Date & Time: Saturday September 19 from 1 – 4pm.

Workshop Schedule:
- Part 1: Up Close and Personal (Indoor Session) We’ll begin indoors, looking at 20+ distinct species collected and laid out on tables. You’ll learn basic identification skills and get your eyes accustomed to the subtle details of different mosses and liverworts.
- Part 2: In the Wild Context (Field Excursion) Next, we’ll explore a nearby forest habitat to see how these species live in community with the greater ecosystem. We will explore various micro-habitats and responsibly harvest a few samples to bring back.
- Part 3: Meet the Neighbors (Microscope Lab) We will wrap up our session in the lab using microscopes to peer deep inside the moss canopy. You’ll meet the “Who’s who” of microscopic wildlife – tardigrades, rotifers, mites, and more – that build their entire lives inside these emerald forests.
Who is this for? Curious adults at a beginner level. No prior botanical or microscope experience is required!
