Abstract
Acute and chronic stresses in forest ecosystems can reduce growth or vigour of trees, and cause changes in their physiology or chemical contents. Ethanol, acetaldehyde, ethylene, and ethane are volatile compounds often produced in stressed, dying, or recently dead trees. Ethanol accumulation is ecologically important because it attracts insects that attack and damage trees, or spread disease. In addition, there are other chemicals conferring resistance to insects and disease, but they decrease in concentration under stress. Monitoring these compounds can assist in timing the lifting of nursery seedlings, detecting harmful effects from air pollution, confirming the presence of root disease, or identifying trees at risk to insect attack. Chemical indicators of stress have potential to be used in monitoring forest health across various scales, but not enough is yet known about options and techniques.
