Crawling - spreads from bush to bush
Crown - spread at an incredible pace through the top of the forest. These are dangerous as it can deprive people under the fire of oxygen to feed the fire.
Jumping / Spotting - Burning branches and leaves carried away by wind

Answer:
The most common hazard in forests is forests fire. Forests fires are as old as the forests themselves. They pose a threat not only to the forest wealth but also to the entire regime to fauna and flora seriously disturbing the bio-diversity and the ecology and environment of a region. During summer, when there is no rain for months, the forests become littered with dry senescent leaves and twinges, which could burst into flames ignited by the slightest spark. The Himalayan forests, particularly, Garhwal Himalayas have been burning regularly during the last few summers, with colossal loss of vegetation cover of that region.
