Book Description
In the early 1980s there were several published reports of recent, unexplained increases in mortality of red spruce in the Adirondack Mountains and the northern Appalachian Mountains of the eastern United States. These reports coincided with documentation of reductions in radial growth of several species of pine in the southeastern United States, and with the severe, rapid, and widespread decline of Norway spruce, silver fir, and some hardwoods in central Europe. In all of these instances, atmospheric deposition was hypothesized as the cause of the decline. (Throughout this volume, we use the term "decline" to refer to a loosely synchronized regional-scale deterioration of tree health which is brought about by a combination of stress factors. These may be biotic or abiotic in nature, and the combinations may differ from site to site. ) Heated public debate about the causes and possible cures for these forest declines ensued. Through the course of this debate, it became clear that information about forest health and air pollution effects on forests was inadequate to meet policymakers' needs. Ecology and Decline of Red Spruce in the Eastern United States addresses that gap for eastern spruce fir forests and represents the culmination of a great deal of research conducted in recent years. The focus is on red spruce because the decline of red spruce was both dramatic and inexplicable and because of the great amount of information gathered on red spruce.

Stand Basal-area and Tree-diameter Growth in Red Spruce-fir Forests in Maine, 1960-80

Book Description
S2Stand basal area change and individual surviving red spruce d.b.h. growth from 1960 to 1980 were analyzed for red spruce-fir stands in Maine. Regression modeling was used to relate these measures of growth to stand and tree conditions and to compare growth throughout the period. Results indicate a decline in growth. The regression models helped identify trends and relationships but were not useful for predicting growth due to the tremendous amount of variability in the growth of red spruce-fir stands. S3.

Effects of Accumulation of Air Pollutants in Forest Ecosystems

Book Description
This volume is based on a workshop on "Effects of accumulation of air pollutants in forest ecosystems'; held in GOttingen, Federal Republic of Germany, from May 16-18, 1982. This work'shop was initiated and sponsored by the Environmental Agency of the Federal Republic of Germany (project officer: Dr. J. Pankrath) as part of a research contract (project leader: Dr. B. Ulrich). THE PROBLEM SEEN UNDER THE ASPECT OF ADMINISTRATION The problem of forest damage caused by air pollution is not new in Europe. Already in 1983 a comprehensive report from Schroeder and Reuss about vegetation damages by fume in the Harz mountains was published. In 1923, Prof. Dr. Julius Stocklasa of the Bohemian Technical Highschool in Prague was concerned with research of toxical effects of sulphur dioxide in his publication "The damage of vegetation by flue gas and exhalations of facili ties". This comprehensive and instructive work concludes with the sentence: "It is already high time for the governments of all cultural states to take legal, police and private measures in order to prevent damage by flue gases". In the neighbourhood of industries with high gaseous and dust emissions damages have been shown to occur for a long timei these deleterious effects have influenced the growth of trees and in extreme cases have even caused their early death.

Book Description
Red spruce is a shade-tolerant conifer whose distribution and abundance reflect Quaternary climate history as well as natural and anthropogenic disturbances. This species once extended further south than its present localities, because of natural and anthropogenic disturbances such as logging, windthrow, and fire. Little is known about the disturbance regime of this species, because long term stand dynamics are difficult to obtain. This-long lived species is hypothesized to be suffering a decline in radial growth, density and abundance at the present time. Recent research suggests pollution, biotic stresses, climate change and natural stand dynamics are the driving forces behind these decreases. The purpose of this study is to investigate the influence of fire in a mesic ecosystem, specifically a high-elevation red spruce (Picea rubens Sarg.) forest on Whitetop Mountain in the southern Appalachian Mountains. Six plots were established in a high elevation red spruce stand to characterize the stand composition. Tree ring data were collected to investigate radial growth relations to inter-annual climatic variability and cross-sections were used to investigate fire history. Red spruce continued to establish throughout the 19th century until a severe fire occurred in 1919 and caused a new cohort of yellow birch (Betula alleghaniensis Britt.) to establish within the stand. Logging and fire caused high mortality in the stand, yet many spruce remain that outdate the past disturbances. Red spruce saplings continue to persist in the stand, showing regeneration despite the abundant hardwoods. Moisture was the main contributing factor to red spruce growth in the dendroclimatic analysis. Red spruce radial growth was significantly correlated to high precipitation and low temperatures of the previous growing season, which is similar to recent research results. This study collaborates the current literature on red spruce growth along with the results found here in creating a model to represent the growth characteristics of red spruce when inter-mixed with hardwoods after a severe disturbance.
