The World of Lichens

Lichens cover 6-8% of the Earth’s land surface, but most people are unfamiliar with these life forms, which attach themselves to rocks, tree bark, or soil. A lichen is a combination of a fungus and either an alga or a cyanobacterium, and more than 15,000 species of lichens have been identified worldwide, including 3,600 in North America and over 700 kinds of lichen in Ohio.  

This lichen program is being co-hosted by Secrest Arboretum and the Ohio Natural Areas & Preserves Association (ONAPA)

Participants will receive a free copy of the Ohio Division of Wildlife brochure, Common Lichens of Ohio Field Guide, written by lichenologist Ray Showman and illustrated with beautiful color photographs of more than fifty species of Ohio lichens by lichen expert Bob Klips.
