The CCC has also developed methods for taking cuttings from live trees in order to maintain a living library of the genetic diversity found in Canada's remaining chestnuts, some of which show signs of natural resistance to chestnut blight
, a fungus that originated in Asia, was first noted in the United States in 1904 at the New York Zoological Garden.
The outbreak of chestnut blight
fungus (Cryphonectria parasitica) from imported chestnut stock was first observed in New York and spread like wild-fire.
The American chestnut, which was virtually eliminated from Appalachian forests in the early 20th century by the chestnut blight

They were decimated by 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.
