Mosses are something that stay in the background, but if you pay attention, they are in the background nearly everywhere you look. Bring mosses into focus as we hike along learning some basics of moss biology and how to distinguish some of the common moss groups. Natural Discoveries is an award‑based series of free nature programs designed for ages seven to adult. Themed hikes are held on Sundays, and hikes that explore seasonal happenings are offered on Wednesdays. Please visit the park district’s website for a brochure listing complete hike details and dates. No registration is required.
