Lichens are a vital yet overlooked part of the ecology in our urban areas.  Seattle has its very own lichenologist, Dr. Katherine Glew, who has researched lichens in Norway, the Russian Far East, and throughout Washington State.  She will discuss lichens; explain what they are, how they grow, and the common types found in the urban ecosystem.  She will also address common lichens found in Seattle and discuss what their existence 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/UW Botanical Garden.

We will meet in the morning at the UW Botanic Gardens and locate common urban lichens. In the afternoon we will move to Hitchcock Hall, on campus, to examine lichens in further detail.

Offered through the North Cascades Institute.
