The Asian trees carried immunity to the fungus, but no such immunity was present in the stately American chestnut
and the fungus spread like wildfire through the forest.
Chestnut blight (Cyphonectria parasitica) and Dutch elm disease (Ophiostoma ulmi), are two other well known invasive tree diseases that have devastated the American chestnut
and the American elm, effectively eliminating them as significant components of the deciduous forests of south eastern Canada.
Within a couple of decades the Chestnut blight fungus virtually wiped out the American Chestnut
, once a dominant species in Eastern hardwood forests.
Encouraging recent advances in the scientific community's efforts to reintroduce the blight-devastated American chestnut
to the eastern United States has led us to revisit the topic nearly ten years later.
These results indicate that American chestnut
is drought tolerant at low volumetric water contents.
After the devastation last century by American chestnut
blight (Endothia parasitica), chestnuts are making a comeback in the United States with a project based at Michigan State University.
Working cooperatively with the American Chestnut
Foundation, the long-term goal is to produce a genetically engineered, blight-resistant American chestnut
His ambition is to develop a new variety--the Walker chestnut--resistant to the blight that had wiped out the original American chestnut
The National Fish and Wildlife Foundation, ALCOA, the Disney Wildlife Conservation Fund and the Lyndhurst Foundation have pledged support to the Charlie Chestnut program -- an e-learning initiative of the American Chestnut
Foundation, a nonprofit organization in Bennington, Vt.
In 1904, a fungus (Cryphonectria parasitica) from Asia that was first discovered in New York City cost us our precious American chestnut
trees (Castanea dentata).
For example, the virtual elimination of the American chestnut
as a dominant canopy tree in the mid-Atlantic forests of the United States, by the 1930s, due to fungal blight, has apparently led to no extinctions or grave threat to survival of other species, including the chestnut-eating gray squirrel.
Kolin examines various historical productions and interpretations of a great American chestnut
