The Hidden World of Lichens with Gillian Harris

Discover the Hidden World of Lichens, led by naturalist and artist Gillian Harris! Lichens, which are a unique partnership between fungi and algae or cyanobacteria, are more than just “mossy stuff” on trees and rocks; they’re fascinating indicators of air quality, habitat diversity, and ecosystem health. As we hike, we’ll observe these often-overlooked organisms in their many forms and learn about their biology, where they live, and why they matter.
