Critical Fire Risk

---

Fire plays an important role in ecology, helping to rejuvenate disturbance-driven systems and bring diversity to the age and type of plants in the forest. In the last century, however, humans have changed when and where fires happen on the landscape—sometimes starting fires themselves, sometimes preventing fires from spreading.

For the FHI, the indicator for fire risk rates how likely to occur unplanned forest fires are by looking at a combination of factors that create fire-ready conditions, such as air temperature, rain, dryness of the air, and wind.
