This workshop will introduce participants to lichen biology, ecology, and diversity. We will start the workshop in the classroom with an introduction to lichens and a discussion of some of the ways and places that lichens grow. Then we will go on a short walk with an introduction to some of the common lichens of Maryland and a demonstration of how to collect, label, and store specimens. Then we will spend the next 2 hours in the lab, viewing the features of the lichens we’ve collected under the microscopes and using keys to identify them. Participants will also have the option to bring their own specimens to identify. Participants should bring walking shoes and outdoor clothes appropriate to the weather as this event will take place rain or shine. We will provide hand lenses for participants to observe the lichens in the field (but we encourage you to bring your own if you have one!) and microscopes will be available in the lab.

Natalie Howe has been studying lichens with high or low intensity for the past 14 years, and currently lives in Washington DC. She is a Biological Scientist at the U.S.D.A., and an adjunct teacher of Mushrooms, Molds, and Society class at George Mason University. In the pre-covid times, she was volunteering with the lichen team at Patuxent Research Refuge in MD, Rock Creek Park in DC and at Liberty State Park in NJ to document the lichens there. For her dissertation research at Rutgers University in New Jersey, she studied the ecology of lichens in the NJ Pinelands.
