When a fire does burn, thousands of lodgepole pine cones are able to open and reseed the area quickly. Tree species such as fir and spruce are not as fire tolerant. The catch in this, of course, is that this all happens in a natural mountain forest environment. To find out more about this, see Effects on Watersheds and Ecosystems . Tree species such as Douglas Fir can tolerate many cycles of low intensity fire.
Tree rings reveal when fires occurred during the tree's life.
