Effects and consequences
- Natural cycles of forests are seriously disrupted when the frequency of forest fires in a particular region is high, causing disappearance of native species.
- Levels of carbon dioxide in the atmosphere, contributing to the greenhouse effect and the climate change.
- Fires in forested areas of the planet erodes the ground, leading to floods and landslides.
- The ashes produced by the fires destroy the earth’s own nutrients which do not regenerate again.

What is the environmental impact of forest fires?
Wildfires can also affect the water quality of streams, rivers, lakes, and reservoirs for years and even decades following a catastrophic fire. Another significant impact of wildfires is the considerable increase in stormwater runoff. After the loss of vegetation, the soil becomes “hydrophobic,” meaning it cannot absorb rainfall.

Natural causes - Many forest fires start from natural causes such as lightning which set trees on fire. However, rain extinguishes such fires without causing much damage. High atmospheric temperatures and dryness (low humidity) offer favorable circumstance for a fire to start.
How do forest fires affect plants?
Fire intensity affects plant response to fire and is often used in the management of woody species. The bark of older trees and shrubs commonly insulates the plant from the heat of low-intensity fires, but smaller stems and seedlings are killed. High intensity fire, however, can top-kill the larger trees.
What are the causes and effects of wildfires?
90% of all wildfires are caused by humans. Human acts of carelessness such as leaving campfires unattended and negligent discarding of cigarette butts result in wildfire disasters every year. Accidents, deliberate acts of arson, burning of debris, and fireworks are as well other substantial causes of wildfires.

Clearly, when people breathe wildfire smoke, the short-term health effects can range from eye and nasal irritation and coughing to worsening asthma, heart attacks, and strokes.
What are positive effects of wildfires?
Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil. Reducing this competition for nutrients allows established trees to grow stronger and healthier.
What are the effects of wildfires on animals?
Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals' ability to thrive in the altered, often simplified, structure of the postfire environment.

How Forest Fires Start
Three elements are required in order for a forest fire to start: fuel, oxygen, and a heat source. Fuel is any flammable material, and a forest is full of these—trees, brush, grass, and small cabins. The air provides oxygen, and both humans and the environment have the ability to provide the heat source.
Types of Forest Fires
There are two different types of forest fires: surface fires and crown fires. Surface fires spread along the ground of the forest. Twigs, dry leaves, and other debris are engulfed in flames as it spreads. Crown fires burn trees up their entire length and spread quickly through the canopy.
How Are Forest Fires Fought and Contained?
Forest fires are contained by a wide variety of strategies, depending on the location and size of the fire. For smaller fires, firefighters often use a tool called a “flapper” to smother small patches of fire and stop spreading. A line of vegetation is cleared around the fire to further avoid spreading.
Human Impact of Forest Fires
Forest fires can quickly wipe out large patches of land or destroy many homes and local businesses, taking lives in the process. Firefighters who risk their lives to fight the fire can develop serious health problems due to smoke inhalation.
Environmental Impact of Forest Fires
Forest fires are often devastating to the environment. Ground cover is necessary to protect the soil. If all of this vegetation is burned away, the soil is left exposed to the elements. Heavy rain can degrade soil and cause flooding and erosion.
Controlled Burns
There is only one particular instance in which forest fires are intentional. Controlled burns are often used by forest management to benefit the forest. This puts a whole new spin on the phrase "fight fire with fire."
How Can You Help Prevent Forest Fires?
Since the majority of forest fires are caused by humans, it is extremely important to be aware of your actions. This is true year-round but especially true during the hot, dry summer months. Respect all fire bans, completely extinguish campfires and never leave them unattended, and don’t throw cigarette butts into nature.
