Book Description
The 1977 Clean Air Act legally mandated the prevention of significant deterioration (PSD) of air quality related values (AQRVs) on wilderness lands. Federal land managers are assigned the task of protecting these wilderness values. This report contains guidelines for determining the potential effects of incremental increases in air pollutants on natural resources in wilderness areas of the National Forests of California. These guidelines are based on current information about the effects of ozone, sulfur, and nitrogen on AQRVs. Knowledge-based methods were used to elicit these guidelines from scientists and resource managers in a workshop setting. Linkages were made between air pollutant deposition and level of deterioration of specific features (sensitive receptors) of AQRVs known to be sensitive to pollutants. Terrestrial AQRVs include a wide number of ecosystem types as well as geological and cultural values. Ozone is already high enough to injure conifers in large areas of California and is a major threat to terrestrial AQRVs. Aquatic AQRVs include lakes and streams, mostly in high elevation locations. Current sulfur and nitrogen deposition is probably too low to warrant immediate concern in most areas (with the exception of nitrogen deposition at some locations in southern California), although the low buffer capacity of many aquatic systems in California makes them sensitive to potential future increases in acidity. Visibility is considered as a discrete AQRV. Guidelines are presented for determining degradation of visibility based on sensitive views in wilderness areas. Estimates of current deposition of ozone, sulfur, and nitrogen are compiled for all California wilderness areas. Recommendations are included for resource monitoring, data collection, and decision criteria with respect to the disposition of permit applications.

Book Description
Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results from the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Lichen Community Indicator covering the first full cycle of data collection (1998-2001, 2003) for Washington, Oregon, and California. During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate.

Oxidant Air Pollution Impacts in the Montane Forests of Southern California
Author: Paul R. MillerPublisher: Springer Science & Business Media
ISBN: 146121436X
Category : Science
Languages : en
Pages : 445
Book Description
This volume presents a body of research conducted over more than thirty years, including an intensive interdisciplinary five-year study begun in 1991. Chapters include studies of the relationships of biogeography and climate to the region's air pollution, the chemical and physiological mechanisms of ozone injury, as well as the impacts of nitrogen-containing pollutants and natural stresses on polluted forests.

Lichens of California
Author: Mason E HalePublisher: Univ of California Press
ISBN: 9780520057135
Category : History
Languages : en
Pages : 254
Book Description
A close look at rocks and trees is often rewarded by the orange or yellow mosaic patterns of some of California's 1,000 species of lichens; yet few people know anything about their unusual compound nature (part alga, part fungus) and most lichens don't even have common English names. This convenient guide, the first ever on California lichens, describes the appearance, habitats, and ranges of over 350 species, 48 of which are illustrated in color, with many others shown in black and white. For weavers and fabric manufacturers, the brilliance of lichen colors provides unusual textile dyes. For scientists, the sensitivity of lichens to air pollution makes them useful biomonitors for environmental studies. For nature lovers they can be an unending source of fascination, and Lichens of California offers convenient identification keys, range maps, and chapters describing the structure, chemistry, and ecology of lichens.
