Fire Ecology of Pine Forests of Northern Eurasia

Abstract

Natural fire caused by lightning and volcanic eruptions have occurred in different biomes of the globe long before the appearance of humans and have been recurring to the present day. Like many other types of natural ecological disturbances, they are not a random occasional phenomenon but represent a regular cyclic event. The frequency of lightning-caused fires correlates not only with the climate and type of vegetation but also with magnetic properties of the earth's crust (Novgorodov et al. 1982).
