Maintaining or increasing stand productivity is the concern of forest
land managers worldwide. Consequently, there is increasing interest in
understanding the impact of environmental stress on productivity and the
development of management strategies that ameliorate or reduce the
deleterious effects. Invited scientists gathered in Fort Collins,
Colorado on July 30, 1985, to present the current state of knowledge
regarding the impact of environmental stress on forest stand
productivity. Particular attention was given to elucidating the mode of
action by which individual stress elements reduce productivity.
Environmental factors and the levels that constitute stressed
(suboptimal) conditions in forest stands were identified, and the
effects of stress intensity and duration on key stand parameters,
including photosynthesis, respiration, assimilate partitioning,
senescence and mortality, were emphasized. The role of genetics and
silvicultural treatments in lessening the stress impact on stand
productivity was presented, particularly in regards to alternative
methods for environmental stress management. Modeling of stand dynamics
in response to environmental stress was explored as an effective
research and management tool. VIII Improved forest management practices
will develop as we improve our understanding of the nature of important
environmental stresses and as we comprehend their impact on tree and
stand performance, manifested through physiological processes and
genetic potential. This book is dedicated to such an understanding and
comprehension.
