2018 Fall Poster Session
The American Chestnut Foundation® (TACF) leads the effort to restore the American chestnut, bringing this important issue to the forefront of current conservation initiatives. The TACF Annual Meetings bring together scientists, conservationists, private landowners and industry professionals to share information and perspectives about the American chestnut and inspire reintroduction of this species to eastern forests. The meetings provide an opportunity to enhance awareness of the importance of American chestnut restoration, explore partnerships, exchange information and discuss this exciting project with a wide audience.
The Poster Session
TACF’s poster session aims to recognize the breadth of topics under investigation in the name of species restoration. It is a great way to expose attendees to the most current research, and the variety of American chestnut projects being pursued. Research posters address topics relative to American chestnut restoration and include, but are not limited to:
- Silviculture and forest management
- Chestnut blight, Phytophthora cinnamomi (ink disease) and other pests and pathogens
- Forest genetics
- Restoration and reintroduction
- Mine-land reclamation
- Forest and wildlife ecology
- History
- Timber value/use
- Breeding and biotechnology
- Other topics related to American chestnut
Year on year, the Poster Session is a highlight of the Fall Annual Meetings, and 2018 was no exception. 17 posters were presented, contributed by members, chapters and students from schools around the country. Please see the complete guide to the presentations in the 2018 Poster Session Abstracts below.

The Student Competition
Since 2015, a competition has been held for the student poster presenters. All students (undergraduate, graduate, high school, etc.) are welcome to participate and judges from TACF’s scientific community assess the posters themselves, as well as the students’ presentation of their work. Judging is held just prior to our Saturday Night Gala dinner, where the winners are announced and presented with their cash awards and certificates. 2018 brought six student presenters to the competition.
