Forest fires are one of the key factors that play a significant role influencing and shaping the forest ecosystems. In a natural ecosystem where the fire took place, it is known that many plant species demonstrate various adaptations at the point of survival or self-renewal after the fire. A number of hypotheses put forward that a direct impact of fire severities and the ignition time of fire on the plant (fuel characteristics) combustibility is associated with physical properties of plants. However, prior studies that prove a relationship between flammable properties of plants and survival of the plants after fires are quite insufficient. In this review paper, the relationship between fire and phenolic compounds that have an effect on the flammability, and the relationship between flame geometry and the ignition time of the chemical components in forest fire were examined.
