From the Discussion ... 'This paper has dealt with the lightning effects and influences that cause primary concern in protection of the forest complex -- forest fire, mortality, injury, and damage from insects and diseases. Although it was written within the framework of protection-oriented research, it should not be construed to indicate that either the author or his organization considers lightning fire and other lightning effects are always and irrevocably harmful. Indeed as Vogl points out, some effects of lightning are beneficial: the culling of overmature and insect- and disease-ridden trees; the needed thinnning and other beneficial treatments of forest stands; and apparently, even the perpetuation of certain tree species....Recognizing the useful aspects of lightning effects, the aim of forest protection research is NOT ultimately the exclusion of all lightning and its effects, but a greater understanding of both and the ability to predict and exercise some control over them for the continuing benefit of mankind.'
