The drought resistant, late blooming
chestnut tree was a dependable and year-round
source of food for humans, livestock and
wildlife in America. Chestnut trees were
once so numerous along the eastern forests
of the U.S. that it is said a squirrel
could jump from chestnut tree to chestnut
tree all the way from Georgia to New York
without ever touching the ground.
At the turn of the century, an imported
"Chestnut blight" or bark fungus
attacked The American chestnut trees.
This blight arrived in the last 1800s
and began to infect the native trees.
By the 1930s the trees were virtually
all killed or reduced to scattered shrubby
sprouts.
After nearly 100 years of efforts to
cure and restore the Chestnut tree, the
status of the Chestnut tree in the wild
has changed very little. Efforts are now
being made to re-introduce a disease resistant
variety of the American Chestnut Tree.
Breeding of resistant American Chestnut
trees and intercrossing their offspring,
genetically engineering resistance genes
into the American Chestnut, using hybrids
or crossing American and other resistant
Asian Chestnuts and a natural remedy called
hypovirulence, a virus infection, slows
the fungus and allows the trees to recover,
are all methods currently being explored
to restore the Chestnut.
