Download or read book Ozone Injury in West Coast Forests written by Sally J. Campbell and published by . This book was released on 2007 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six years of monitoring for ozone injury by the Pacific Northwest Research Station Forest Inventory and Analysis Program are reported. The methods used to evaluate injury, compute an injury index, and estimate risk are described. Extensive injury was detected on ozone biomonitoring sites for all years in California, with ponderosa and Jeffrey pines, mugwort, skunkbush, and blue elderberry showing injury. Little or no injury was detected in Oregon and Washington. The relation of observed injury to ambient ozone levels is discussed. The areas with the highest modeled risk of ozone injury are the areas east of Los Angeles, the southern Sierra Nevada, and portions of the central coast.

Download or read book Ozone Bioindicators and Forest Health written by Gretchen Cole Smith and published by . This book was released on 2008 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1994, the Forest Inventory and Analysis (FIA) and Forest Health Monitoring programs of the U.S. Forest Service implemented a national ozone (O3) biomonitoring program designed to address specific questions about the area and percent of forest land subject to levels of O3 pollution that may negatively affect the forest ecosystem. This is the first and only nationally consistent effort to monitor O3 stress on the forests of the United States. This report provides background information on O3 and its effects on trees and ecosystems, and describes the rationale behind using sensitive bioindicator plants to detect O3 stress and assess the risk of probable O3 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.

This book was released on 2003-05-22 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book contains information on geology, climate and vegetation of the Sierra Nevada with a special emphasis on air pollution effects on the mixed conifer forests. A history of the extent of air pollution effects on mixed conifer forests, especially ponderosa and Jeffrey pines is provided. The physiological basis for ozone-type injury development in ponderosa pine, a discussion of ozone uptake by plants at different levels of biological organization and the effects of air pollution and other stresses on mountain forests are discussed. A considerable portion of the book is dedicated to development of statistical models and maps of ambient ozone distribution in the Sierra Nevada based on the 1999 monitoring data with passive samplers. The implications of the methodological results, formulation and application of regional air quality models for integrated assessment of urban and wildland pollution and the need for functionally integrated models of ozone deposition to the Sierra Nevada forests are also discussed. Management and monitoring needs for improved long-term understanding air pollution effects on forest ecosystems, discussion of options for proper management of the air pollution affected forests, and comparison of monitoring and modelling of ozone and forest health status in the Sierra Nevada with similar efforts in mountains of North American and European mountain ranges are the focus of the later chapters of the book.
Download or read book Ozone Bioindicator Sampling and Estimation written by Gretchen Cole Smith and published by . This book was released on 2007 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ozone is an important forest stressor that has been measured at known phytotoxic levels at forest locations across the United States. The ozone bioindicator data of the U.S. Forest Service Forest Inventory and Analysis Program (FIA) are the only source of information available that documents plant injury from air pollution using consistent protocols. This document introduces the FIA ozone indicator and describes the sampling and estimation procedures of the national biomonitoring program. It provides background material on ozone, examples of bioindicator summary statistics, a description of spatial interpolation, and methods to estimate status and change in forested areas with respect to the occurrence of ozone injury from ambient ozone concentrations. The goal is to provide guidance to analysts and researchers on ways to incorporate ozone bioindicator data into reports and research studies.

Book excerpt: This report highlights key findings from the most recent (2001-2005) data collected by the Forest Inventory and Analysis Program across all forest land in California. We summarize and interpret basic resource information such as forest area, ownership, volume, biomass, and carbon stocks; structure and function topics such as biodiversity, forest age, dead wood, and hardwood forests; disturbance topics such as insects and diseases, fire, invasive plants, and air pollution; and information about the forest products industry in California, including data on tree growth and mortality, removals for timber products, and nontimber forest products. The appendixes describe inventory methods in detail and provide summary tables of data, with statistical error, about the suite of forest characteristics inventoried.
