Chestnut Chat Series
Want to engage in real-time conversation and presentations that cover all things related to American chestnut restoration? TACF’s live Chestnut Chat Series takes place every third Friday of the month to keep you updated on our work, share experiences, and offer participants the opportunity to ask questions. All sessions are recorded and available below for those who aren’t able to join the live sessions.
Join us on Friday, August 20, at 11:30 AM (EDT) for the next LIVE Chestnut Chat, Participatory Chestnut Breeding.
Hear Ron Revord, PhD, Assistant Research Professor, University of Missouri Center for Agroforestry, and Dr. Greg Miller, owner of Empire Chestnut Company, founder of Route 9 Cooperative, and prior board member of TACF, tackle what is involved in establishing a network to characterize genetic diversity and ancestry of on-farm germplasm.
LEARN HOW TO PARTICIPATE
Chestnut Chat 26: Chestnut Chat, Emerging and Evolving Threats to Chestnut Health

Emily Dobry, M.S. candidate in horticulture at Penn State College of Agricultural Sciences, and Carol Mapes, a Biology Professor and former Chair of the Kutztown University Biology Department, will discuss these and other challenges we strive to tackle when working with chestnut.

Chestnut Chat 22: Exploring Big Questions for American Chestnut Restoration
Topic: Explore big questions, such as what makes a native plant native? Why is American chestnut restoration important? Who and what will benefit from the tree’s restoration? We will tackle all questions associated with American chestnut restoration, and other restoration projects. Staff, members, and volunteers often face these questions and, rather than a single answer, there is often a spectrum of possibilities.
