Why are wildfires raging?
What is driving this trend? Many factors have come together to create a perfect storm. In recent decades, development has pushed into areas with fire-prone ecosystems—the wildland-urban interface. Many of these drivers are beyond the Forest Service’s control.
This of course begs the query “What is the main cause of wildfires?”
Wildfires require a spark and fuel. In the forests of the Western United States, half of wildfires are initiated by lightning. The other half are human-caused — frequently started by power lines, cigarettes, cars, camp fires or arson.
Why are wildfires getting worse in the west?
Poor forest management, allowing a buildup of grasses, shrubs, fallen branches and small trees that can serve as fuel for wildfires, has also contributed to the intensifying fire season. Some of the fires raging in the West are threatening places that were hit by colossal blazes just a few years ago.
You might be wondering “Why are wildfires getting bigger?”
They are growing larger, spreading faster and reaching higher, scaling mountain elevations that previously were too wet and cool to have supported fires this fierce. They are also getting more intense, killing a greater number of trees and eliminating entire patches of forest.
As Americans move closer to the frontiers (called the wildland-urban interface or WUI), they are moving closer to the forests, brush and grasses that provide fuel for destructive fires.
How do people react when a wildfire occurs?

Then, how does a house burn down in a wildfire?
Between 60 to 90 percent of homes lost to wildfire are due to embers carried by wind ahead of a fire. If an ember lands on a house, or on mulch beneath a window, or enters an attic through a vent, it can ignite, setting the house on fire.
