Lichens are a vital yet overlooked part of the ecology in our urban areas. 

Dr. Katherine Glew will introduce lichens, explain what they are and how they grow.  She will also address common lichens found in Seattle and provide a list. You will find out what their presence in the city tells us about your plants and air quality. Bring your hand lens if you have one, since there will be plenty of lichens to find. We will spend part of the day in Washington Park Arboretum, University of Washington Botanical Garden. To Study lichens in more detail, we will have an opportunity to use microscopes to see their fascinating details.

Katherine Glew has researched lichens in Norway, the Russian Far East, and throughout Washington State.
