Flight 93 staff have partnered with scientists and foresters from the American Chestnut Foundation to plant seedlings they hope will be the first in more than a century to withstand an invasive fungus known as the chestnut blight
Once a common sight, reigning over 200 million acres of eastern woodlands from Maine to Florida, the American chestnut tree disappeared from this area during the first half of the 20th century because of a lethal fungus infestation known as the chestnut blight
Tree health is crucial to the countryside and the rural economy, and we will continue to work closely with Defra to protect our trees from sweet chestnut blight
, Chalara, Phytophthora and other pests and diseases.
Environment Secretary Owen Paterson announced the ban after a six-week consultation, which received "overwhelming support" for stopping imports from areas such as France which are affected by sweet chestnut blight
But with aspirations of a convenient cash crop came a fungus disease called chestnut blight
, an organism that crept under their split bark, slipped into their vascular system and triggered cankers.
(Cryphonectria parasitica) was introduced into the United States around 1904.
Within a few decades, the chestnut blight
killed up to three billion American chestnut trees on over 200 million acres of woodland.
If it becomes established in the United States, the invasive insect has the potential to cause more damage than Dutch elm disease, chestnut blight
, and the gypsy moth combined--destroying millions of acres of our hardwoods, including national forests and parks and even our own backyard trees.
At one time, woodrats were found in 41 Pennsylvania counties, but the 20th century's American chestnut blight
and gypsy moth invasion - other imports from Asia - and substantial changes in land use have conspired to create huge habitat deficiencies and insurmountable barriers in the woodrat's world.
At the beginning of the last century, the chestnut blight
, caused by a fungus, rapidly spread throughout the American chestnut's natural range, which extended from southern New England and New York southwest to Alabama.
Recent additions to the collections include seven species of fungi in the chestnut blight
group that were discovered and described in the past few years.
The outbreak of chestnut blight
fungus (Cryphonectria parasitica) from imported chestnut stock was first observed in New York and spread like wild-fire.
