The Cali fires are mainly in Eucalypt Forest, imported from Australia around 100 years ago.
The best way to maintain Australian eucalypt forest, is by yearly burning off.
When maintained by fire yearly, keeps the ground litter from building up to create big fire events.
Eucalypt trees are extremely tolerant to fire, which doesn't kill the tree, even when badly burned.
The trees will spring green fresh growth within days of a major fire.
