Join GASP and historian Jennie Benford for a unique educational walk & talk in Homewood Cemetery! Ticket proceeds will benefit both GASP and the Homewood Cemetery Historical Fund.

During this afternoon stroll through part of the cemetery, you will have the opportunity to explore the fascinating relationship between lichen and air quality. Lichen, a symbiotic organism composed of fungi and algae, is a bioindicator of air pollution levels. By observing the presence and health of lichen in the cemetery, you can learn about the air quality in the surrounding area. Once you know what to look out for you'll find yourself keeping an eye out for lichen.

With the help of historian Jennie Benford, who has been involved with Homewood Cemetery for decades, you will also discover the significance of the cemetery as a protected urban green space. Cemeteries often serve as important green oases within urban environments, providing habitats for various plant and animal species. These spaces also offer a peaceful retreat for visitors and contribute to the overall biodiversity of the city. In a city with an industrial history like Pittsburgh's, this dynamic has been even more important.
