POSSIBLE RELEASE OF U.S. GE CHESTNUT TREES INTO THE WILD HIT

On August 18, 2020, the U.S. Department of Agriculture (USDA) published a petition by researchers at the State University of New York College of Environmental Science and Forestry (ESF) seeking federal approval to release their genetically engineered (GE) Darling 58 (D58) American chestnut tree into US forests, Anne Petermann reported for Truthout.

Researchers claim the transgenic D58 tree will resist the fungal blight that, coupled with rampant overlogging, decimated the American chestnut population in the early 20th century. In fact, the GE American chestnut is a Trojan horse meant to open the doors to commercial GE trees designed for industrial plantations.
The D58 would be the first GE forest tree approved in the U.S. and the first GMO intended to spread in the wild. (GE canola plants were discovered in the wild in 2010 but that was unplanned).
“This is a project to rapidly domesticate a wild species through genetic engineering and accelerated breeding, and then to put it back into ecosystems to form self-perpetuating populations — an intentional evolutionary intervention that has never been attempted before with any species,” explain scientists at the Center for Food Safety (CFS) and International Center for Technology Assessment (ICTA), which are nonprofits based in Washington, D.C.
While American chestnut trees are known to live hundreds of years, D58 trees have only been growing since 2017, calling into question the ESF petition assertion that, “Darling 58 has been studied in detail and no plant pest or environmental risks have been observed.”
In a report on the GE American chestnut she co-wrote, Rachel Smolker from Biofuelwatch explains, “Given the long lifespan of trees and varying environmental conditions they face, we cannot extrapolate from tests done on very young trees under controlled lab and field conditions. How GE trees might behave in the diverse and changing context of natural forests over long periods of time is unknown and likely to remain unknown even after they are released.”
“The southern US is global ground zero for the forest products industry and we see GE chestnut trees as this industry’s sneaky way of opening the floodgates for ‘frankentrees’ that will harm forests, biodiversity, and local communities across the region,” explains Scot Quaranda of Dogwood Alliance, a nonprofit based in North Carolina that works to protect southern U.S. forests.
“Our natural forests that support wildlife and the economic sovereignty of rural communities will rapidly be replaced with tree plantations for wood pellets, paper, and more, leaving environmental and climate injustice in their wake.”
The GE American chestnut faces an uphill battle due to decades of opposition to GE trees by Indigenous peoples, scientists, students, activists, foresters, and others, including a GE tree ban by the Forest Stewardship Council and a United Nations decision that warns countries of the dangers of GE trees and urges use of the precautionary principle while addressing the issue.
By October 19, 2020, the close of the public comment period on the petition, 109 organizations, representing millions of members, plus an additional 123,426 individuals had registered their opposition to the D58.
The next step is the creation of a draft Environmental Impact Statement (EIS) by the USDA recommending action on the petition. The American Chestnut Foundation (TACF) estimates this could take up to a year to complete. Following this, another public comment period will be undertaken to review the draft EIS, after which the agency will develop a final EIS with a decision on the petition.
