Chestnut formerly made up around 50% of eastern forest trees before the introduction
of chestnut blight around 1900. The American chestnut had no resistance to the
disease and most remaining in the wild today exist mainly as living stumps that
occasionally grow large enough to flower before being killed to the ground again
by the disease. Attempts have been made to cross breed with Chinese chestnut but
the hybrid trees are not like the original chestnut. More recently, genetic
engineering is being employed to add resistance to otherwise pure American
