COSEWIC Status Reports

COSEWIC assessment and status report on the American Chestnut Castanea dentata in Canada

American chestnut is a member of the beech family. It is the only species of chestnut native to Canada. It has elongate leaves tapered at both ends and large teeth along the margins. Flowers are arranged in catkins with numerous tiny male flowers and a cluster of several female flowers at the base of some of the catkins. When cross-pollinated with another chestnut tree by an insect pollinator, the female flowers develop into spiny bur-like fruits enclosing one to several chestnuts. This species once was a dominant tree in many areas of the eastern deciduous forests of North America, but has been greatly reduced by the introduction of the chestnut blight disease a century ago.
