The once-ubiquitous American chestnut tree is now functionally extinct, nearly erased from the landscape by a blight that killed roughly 3 billion trees over 50 years. Now a nonprofit organization dedicated to restoring the tree is seeking federal approval to release a genetically engineered blight-resistant chestnut into the wild. But is a genetically engineered tree the right way to restore a virtually extinct species?
The blight, an Asian fungus that girdles chestnut trees and eventually kills them, came to North America in around the 1900s. Years of federal and local forestry efforts failed to revive the species. The nonprofit American Chestnut Foundation was formed in the 1980s to continue that work and restore the trees to the wild.
The ACF has bred hybrid trees resistant to the blight, but it's also pursuing a genetically-modified tree that combines genes from wheat and cauliflower into a tree resistant to the fungus. Much of that research is being done at the State University of New York College of Environmental Science and Forestry in Syracuse.
Sara Fitzsimmons, ACF director of restoration and a researcher at Penn State University, joins Vermont Edition to explain chestnut restoration efforts and how the foundation is working toward federal approval to plant its genetically modified chestnut trees in the wild to restore the species.
Fitzsimmons will also discuss the March resignation by two members of the Massachusetts/Rhode Island ACF in protest to the foundation's plans to plant geneticially modified trees and opposition to agrochemical and biotech companies Monsanto and ArborGen being involved in the project.
