Inventory-Based Forest Health Indicators: Implications for National Forest Management

Journal of Forestry, 2003
Abstract Several forest health indicators that are derived from inventory data can be used to compare changes in stand conditions over a 50-year period and across ownerships and regions. National forests, most of which are in the West, are denser and have higher mortality than other forests.
