The Distribution of Surviving American Chestnuts in Michigan

ABSTRACT.--Two-hundred-twenty-four locations of American chestnuts were examined in Michigan between 1975 and 1981. Eighty-four of these locations were diseased while 140 sites were disease-free. Of the 1094 trees recorded with diameters greater than 15 cm d.b.h., a total of 645 were diseased or occurred at diseased sites whereas 349 were located at sites where blight was not observed. Most trees at locations where blight occurs suffered extreme damage during the first few years of infection. However, 24 locations in southwestern Michigan and 5 locations in the Northeast contain trees where superficial cankers are common 10 to 20 years after the disease was first observed.
