Planted Black Walnut in Vermont: A 30-Year Experience

Eastern black walnut (Juglans nigra) is not commonly found in northern New England, however, a warming climate may be altering its ability to survive and grow in this region. In 1993, more than 1,000 commercially obtained black walnut seedlings were planted on an abandoned agricultural field in central Vermont with the goal of timber production. Subsequent management of the site was conducted according to previously established guidelines, including the use of tree shelters, herbicide control of competing vegetation, pruning, and thinning. Survival was 85 percent over a 5-year period. After 30 years, the average diameter at breast height of the trees was 10.18 in (25.9 cm) and timber form was good. With care, black walnut can be established and thrive in northern New England. A regionally adapted black walnut seed source for future assisted migration efforts is now in place.
