Welcome to TCD Ground Zero!
Black walnut is native to much of the eastern U.S., where it is found in many rural and urban areas. It is an important economic forest (valued for wood -- lumber and veneers) and food (valued for nutmeat) resource. Standing black walnut is valued at $569 billion. A new disease called thousand cankers disease, which has killed thousands of trees, now threatens the health and survival of black walnuts in the U.S., particularly in its native range. This disease also has affected other walnut species, including Arizona walnut, English walnut, and California walnut, with varying degrees of susceptibility.
Thousand cankers disease is caused by a canker-producing fungus (Geosmithia morbida) which is carried by the walnut twig beetle (Pityophthorus juglandis). Our goal is to share information on this potentially devastating disease to enhance knowledge to reduce its spread and impact on black walnut.
