A nonprofit organization dedicated to restoring the American chestnut
to its native eastern forests, The American Chestnut
Foundation (TACF) has taken part in a painstaking effort that involved crossing the tall American chestnuts
with the much shorter, blight-resistant Chinese chestnuts, planting them and waiting for the seedlings to grow--a time frame of 6 to 7 years.

We see no better example of that than the planting in Worcester's Green Hill Park this past Arbor Day, of 15 "back-crossed'' American chestnut
In the process, they've become part of an innovative but long-shot effort to restore one of America's lost icons: the American chestnut
Chestnut Hill Tree Farm specializes in growing Dunstan hybrid chestnuts, a blight-resistant variety that is a cross between a disease-resistant American chestnut
discovered in the 1950s and three Chinese chestnut varieties.
When I learned I'd won the residency, I had three months to delve into the history of the American chestnut
tree before arriving at Bernheim, where, I hoped, I would get to see some of the hybrids.
Cryphonectria parasitica is an introduced fungal pathogen responsible for the decline of the American chestnut

In 1904, the New York Zoological Park's (now the Bronx Zoo) chief forester, Hermann Mekel, noticed a fungus on some of his American chestnut

(Castanea dentata) was once a major component of eastern North American forests.
Through a collection of art, photos, stories, poems, anecdotes, and reflections, this volume tells the story of the American chestnut

A June study from Purdue University shows that a new American chestnut
hybrid would not only bring back the near-extinct tree, but also act as a sponge for greenhouse gases.
Washington, June 11 (ANI): A new study by researchers at the Purdue University, US, has shown that that introducing a new hybrid of the American chestnut
tree would not only bring back the all-but-extinct species, but also put a dent in the amount of carbon in the Earth's atmosphere.
We are right on the cusp of seeing the results of our work to develop a tree resistant to blight, but that Looks and grows like American chestnut
