Risks to California Forests Due to Regional Ozone Pollution: A Data Base and Ranking of Forest Sensitivity

摘要

The project collected, calculated, and synthesized biological, economic, geographic, and ozone monitoring data into a gridded data base describing forested areas in California. Current and potential ozone risks to forest areas of California were then estimated. Over 50 percent of the forested areas in 12 California counties, five out of 19 national forests and 13 California watershed designation areas were found to be at high risk to ozone using a .045 ppm, 12 hour seasonal ozone standard.
