About this book
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.
Section 1: Description of Soils, Climate, Natural Resources, and Their Modification by Anthropogenic Influences: Geography, Geology, Geomorphology and Forest Soils * Climatology * Vegetation, Fire Regimes and Forest Dynamics. Section 2: Effects of Ozone and Other Air Pollutants on Vegetation and Soils in the San Bernardino Mountains: Chemical Characterization and Seasonal Change of Ozone and Wet and Dry Deposited Pollutants * Visibility Impairment in the San Bernardino Mountains * Physiological Responses of Ponderosa Pine to Gradient of Environmental Stressors * Temporal Changes In Crown Condition Indices, Needle Litterfall and Colateral Needle Injuries of Ponderosa and Jeffrey Pines * Evidence for Air Pollution Effects on Mature Tree Growth of Ponderosa and Jeffrey Pines and Big Cone Douglas Fir * Effects of Ozone on Understory Vegetation in the Mixed-Conifer Forest * Community Variation in Ephyphytic Lichens in the San Bernardino Mountains in Relation to Oxidant Gradients * Wet and Dry Pollutant Deposition to the Mixed-Conifer Forest * Direct Effects of Nitric Acid on Forest Vegetation * Nitrogen Deposition and Cycling in Mediterranean Forests: The New Paradigm of Nitrogen Excess. Section 3: Interactions of Physical, Chemical and Biological Factors and Their Influences on Forest Health and Forest Use. Section 4: Synthesis and Conclusions, including assessments and implications for policy, management and future research.
