9:30 am - 11:30 am
Scott LaGreca, Visiting Scholar, Duke Department of Biology

Lichens are found in nearly every habitat on Earth. Despite being often overlooked, they are extremely useful indicators of both air pollution and climate change. Come learn about the biology and utility of these fascinating symbiotic organisms with Scott LaGreca, a visiting scholar in Duke's Department of Biology, and a Duke alum with a Ph.D. in botany. Following an overview of lichen biology and their importance as bioindicators, participants will become familiar with lichen growth forms and structures under the microscope. We will then walk across the Gardens, examining and identifying the lichens we encounter on our way, growing on trees, wood, rock and other substrates. Meet in the classroom inside the Doris Duke Center
This will be a small group program that takes place partially seated indoors and partially outdoors traveling on a combination of paved and unpaved paths with some uneven surfaces and moderate inclines.
