The volume contains 35 papers from a Symposium held June 29-30, 1989 in Anaheim, CA. Topics addressed include air quality and deposition, forest condition and growth trends, physiological mechanism of effects, and effects of air pollution on forest soils. Among the conclusions reached at the Symposium were: (1) large areas of forests in California have been damaged by ozone; (2) highly acidic clouds impact forests in Washington, California and Colorado; (3) most western forest soils are not currently at risk from acid deposition; (4) forests in southern Arizona are experiencing unexplained growth declines.
