In 1994, the Forest Inventory and Analysis (FIA) and Forest Health Monitoring programs of the U.S. Forest Service implemented a national ozone (Ob3s) biomonitoring program designed to address specific questions about the area and percent of forest land subject to levels of Ob3s pollution that may negatively affect the forest ecosystem. This is the first and only nationally consistent effort to monitor Ob3s stress on the forests of the United States. This report provides background information on Ob3s and its effects on trees and ecosystems, and describes the rationale behind using sensitive bioindicator plants to detect Ob3s stress and assess the risk of probable Ob3s impact. Also included are a description of field methods, analytic techniques, estimation procedures, and how to access, use and interpret the ozone bioindicator attributes and data outputs such as the national ozone risk map.
