Black Walnut in the Eastern U.S.: Current Status and Recent Trends Based on FIA Data

Abstract

Black walnut (Juglans nigra) has an estimated population of more than 340 million trees and 4.9 billion cubic feet of net volume on forest land across the eastern United States. Over the past decade, the number and net volume of black walnut trees have increased by 11 percent and 23 percent, respectively. This article will examine the factors driving these increases as well as other important variables such as tree damage and seedling regeneration using the latest data from the USDA Forest Service’s Forest Inventory and Analysis (FIA) program. Although orchards are excluded, the analyses give nut growers valuable information on the more suitable regions for growing black walnut and expected growth rates.
