QuoteThe 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.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.Broadcast live on Wednesday, April 3, 2019 at noon; rebroadcast at 7 p.m.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.
QuoteBryan Lightner, a member of the Cecil County Watershed Stewards, led the planting project again this year. He said the American Chestnut Foundation is collecting data on the four species planted: Sugarloaf, WMREC, Carver, and Scrivener.
QuoteThe Bethlehem Authority commemorated Earth Day on Monday by planting hundreds of seedlings aimed at bringing back the mighty chestnut trees that once dominated the canopy of that Carbon County forest surrounding the city's water supply.The planting includes 400 chestnut seedlings and 600 red and white oak on a 2.5-acre patch near Wild Creek Reservoir. The mixed planting aims to mimic the native forest composition that once grew there before a blight decimated chestnut trees a century ago. Over the next several years, the authority will be tracking the seedlings for survival and using the oak species as a control group to learn what the soil will support.

QuotePublic lands biologist Josh Kelly warned last Wednesday that conservation efforts must start now to save North America's ash trees before they face a fate similar to the American Chestnut tree and disappear from forest landscapes.Kelly, with local environmental group MountainTrue, gave his presentation, "Save Pisgah's Ashes," in the library's Rogow Room. The presentation was organized by the library in partnership with MountainTrue and the Pisgah Conservancy.Specifically, the presentation highlighted the dangers infestations of emerald ash borer beetles (EAB) present to woodlands. Kelly emphasized there is still time to save native populations of white, green and Biltmore ash, and that while treatment can be expensive, especially with big trees, removal is even more so.
