Members of the chestnut research team and the property owners are examining a fine American chestnut specimen (dbh 6.2 inches) with no signs of blight.  Another larger chestnut tree (dbh 7 inches) was about 100 feet away and it was equally healthy.  Such trees may have some resistance to the chestnut blight and/or may have been naturally inoculated with a hypovirulent strain of the chestnut blight fungus or they may have just been lucky and have not yet been infected by the virulent strain.
