Lichen Walk at Olompali State Historic Park
Saturday February 15, 2014, 10:00 a.m.2:00 p.m.

You’ve seen it hanging off trees like an old man’s beard and covering rock faces in beautiful sunburst patterns. Now it’s time to learn more about the fascinating fungal-algal relationship known as lichen.
Join California Lichen Society president and lichenologist Shelly Benson for an easy walking tour of Olompali’s amazing lichen. She will teach us about the natural history of lichen, how to identify different species and why they are important indicators of air quality and climate change. The recent rain should ensure that the lichens will be in good shape.

We will also have the opportunity to pilot the new iNaturalist field guide to Olompali lichen.   Lichen Species List for Marin County
