Though Murrill's doomsday predictions for the American chestnut proved true, the tree was never forgotten; efforts to outwit the chestnut blight
began immediately and have never stopped.
No one knew what to do when the chestnut blight
hit in 1904, so for decades many people continued planting Chinese chestnuts anyway--at least they somewhat replaced the nut of the American chestnut, but since they were low-growing, the forest canopy ceded to oaks and beeches.
Thankfully, within the last century, white and red oaks have filled the void caused by the chestnut blight
The American chestnut, which was virtually eliminated from Appalachian forests in the early 20th century by the chestnut blight
pathogen, is being restored through several innovative programs around the country.
They were decimated by chestnut blight
, caused by a bark fungus accidentally introduced into America.
(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.
Graban added that chestnut no longer exists as a commercial timber in the United States because of the chestnut blight
that devastated domestic supplies.
Ever since chestnut blight
was first described at the Bronx Zoo in 1904, scientists have been struggling to defeat it.
These results are important to reintroducing the tree back into the forests and to fighting off the chestnut blight
It offers brief looks at large-scale timbering, forest conservation and the parks movement, and watershed protection (power generation, flood control, and the negative impact of TVA and Corps of Engineers dams on river ecosystems), and finally discussion of the chestnut blight
as emblematic of a threatened forest and forest-based culture.
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.
Plants have suffered their own emerging diseases, such as chestnut blight
, dogwood anthracnose, and sudden oak death syndrome.
Devastating as the chestnut blight
was, it missed some trees.
Fagaceae) was virtually extirpated as a dominant tree species throughout the Appalachian forest region by the 1930s due to the chestnut blight
(Cryphonectria parasitica; Ascomycota).
Farmers of the region have weathered ups and downs of the market, loss of forest grazing with the denudation of the southern Appalachian forests to logging followed by fires and erosion, the loss of close markets when railroads and livestock raising in the west destroyed local industry, and the loss of the valuable American Chestnut tree to the Asian chestnut blight
