Description:

Chestnut Blight is a microscopic, parasitic fungus that infects chestnut trees (Castanea spp.). The fungus, which causes visible orange cankers on the bark, has had a devastating impact on American Chestnut. The tree had little resistance when the fungus was inadvertently introduced in the early 20th century.

Where to find:

Except for the most isolated trees, every American Chestnut tree is infected by Chestnut Blight. You can find the fungus anywhere you find American Chestnut.

There are 45 records in the project database.
