As leafy plants go dormant in the winter, lichens take center stage. Explore the often-overlooked world of lichens that grow on bark, logs, soil, and rocks, playing a crucial role in our ecosystems. Take a guided walk around the sanctuary and learn how to identify common types in the field while discussing the important things they can tell you about the air and the habitats around them. By slowing down and looking closely, you'll discover the incredible diversity of these unique organisms all around us, hiding in plain sight. This program takes place outdoors, walking around 1-1.5 miles. Trail surfaces may be icy or muddy in late February. More details on what to bring and expect will be emailed to you ahead of the program.
