Canadian and US researchers working to conserve American butternut, Juglans cinerea, gathered both virtually and in-person at the Purdue University John S. Wright Center on September 25, 2024, to share results from projects around the region. Butternut, a close relative of black walnut, is a declining and in many locations an endangered tree due in part to a fungal disease called butternut canker. Researchers are examining both the tree and the disease to develop strategies for conservation and restoration of the species. HTIRC and U.S. Forest Service staff have served central roles in research and breeding efforts to conserve butternut genetics and develop strategies for restoration.
To learn more about butternut and ongoing efforts, you can access recordings of the presentations from the workshop on the RNGR Reforestation, Nurseries and Genetic Resources website.
