American Chestnut Restoration: The Life, Death & Rebirth of the American Chestnut in the East Forest

March 23, 2021, Co-Sponsored by the Heritage Conservancy

Mary Ayers, a Pennsylvania Forest Steward and member of the Pennsylvania Forestry Association, reviews the history and struggles of the American chestnut tree. Prior to the 1900s, American chestnut trees were growing throughout the forests of the eastern U.S., but then a blight fungus introduced from Asia spread and killed an estimated 4 billion American chestnuts. The chestnut blight has been called the greatest ecological disaster to strike the world's forests in all of history.

Ayers, through her work with the American Chestnut Foundation (TACF) and her own two-acre TACF research orchard with fifth generation hybrid chestnut trees, describes the latest scientific approaches being used to breed a genetically diverse, locally adapted, blight-resistant American chestnut to be re-established as a keystone species in the eastern forest.  See related resources below.

Environmentalism and the Media

September 10th, 2019

In this talk, Dr. Patrick Murphy mapped how the media communicates today's many distinct, competing, and even antagonistic environmental discourses, demonstrating how the media pushes us to save the whales even as we are encouraged to devour all the fish! He authored Media Commons (2017) among many other publications on the topics of global media, media and the environment, ethnographic method, documentary media, and Latin American media and cultural theory. See related resources below. 


November 29, 2018

Dr. Val Beasley, a Penn State professor of veterinary, wildlife, and ecological toxicology will be speaking about toxicology and environmental contaminants. "'One Health' as a discipline links human and veterinary medicine as co-equal partners in an increasingly efficient joint venture into health promotion and prioritized research. 'One Toxicology' is proposed as a way to reunify toxicology as a component of 'Ecosystem Health' and the encompassing 'One Health'. Ecotoxicology, which includes wild animal, plant and microbial communities, is a critical component of 'Ecosystem Health'. 'One Toxicology' is proposed to help hold toxicological sciences together and maintain intimate connections to medicine in general.'"
