Be Aware: Wildfire Cause and Effect
The consequences of wildfires are always negative. The uncontrolled spread of fire not only causes economically significant damage but also has terrible consequences for the environment. The burning of large areas of forest leads to radical changes in the ecosystems of the affected region, which can ultimately lead to unpredictable results. Forest fires are one of the worst and most dangerous natural disasters in the United States. Large numbers of people and animals are killed each year by the uncontrolled speed of wildfire.
Of course, forests are not the last place in human life and fulfill their certain functions. One of the most important functions of the forest is the production of oxygen. In addition, the forests’ impact on the water regime, protection of the soil from water and wind erosion, mudslides and landslides, reducing the impact of drought and dry winds, restraining the movement of moving sands, preventing the destruction of the banks of rivers and lakes, settling dust particles from the atmosphere, emitting phytoncides, absorbing noise and, very importantly, having a beneficial effect on human health, is no less important.
In addition to all this, forests are a source of obtaining various natural resources, which are simply necessary for the development of many industries in the national economy.
What Cause Forest Fires: The Human Factor
According to statistics, about ninety percent of all forest fires are caused by humans.
There are many reasons for fires caused by human carelessness:
- Smoking. Very often, while outdoors, smokers forget to put out a cigarette butt and throw it just on the ground, where the dry grass spreads the fire at high speed. This can easily be one of the causes of wildfires.
- Campfires in nature. Often, when camping in nature people forget to put out their fires or carelessly leave unattended burning embers, which can easily provoke a fire.
- Burning garbage in villages. Because burned garbage smolders very slowly, it can be one of the wildfires causes.
- Fireworks. More and more often, people are choosing fireworks as their holiday entertainment without thinking about the fact that they can cause a fire. Due to the fact that the rate of combustion is very low, the particles of fireworks land in a variety of places. Thus, the risk of a forest fire is increased.
- Deliberate arson. There are also cases where people deliberately set fire to forests, houses, or any other property.
How Do Forest Fire Start: Natural Factor
The causes of wildfires caused by nature are not numerous, but they are:
- Dry thunderstorms. Despite the fact that this phenomenon is quite rare, it poses a serious threat. Dry thunderstorms are a meteorological phenomenon that occurs when temperatures are high and accompanied by a small amount of evaporating precipitation that does not reach the ground. This is accompanied by thunder and a powerful electrical discharge, which hits the trees, resulting in a fire due to lack of moisture.
- Lightning. Almost always wildfires caused by lightning strikes occur in dry weather. Very often the start of a forest fire caused by lighting has more destructive consequences than those caused by the human factor.
- Volcanic eruption. Fires can be caused by lava that spreads to nearby fields or forests.
- Self-ignition of a peat bog. Peat bog self-ignition can occur if the external temperature is above 122 degrees Fahrenheit.
Wildfire Speed and Types
Depending on the nature of the spread, the following types of forest fires are distinguished:
- grass-roots (the height of the flames is 20-60 inches, the forest fire speed of spread of the fire through the lower layer of forest – 0.3 – 3 mph, at night the speed of spread is lower than during the day);
- high-mountain fires (they follow the low-mountain fires in strong winds at a speed of 3-42 mph, and the flame can reach a height of 40-47 inches);
- underground (appear in areas with dry peat soils, the spreading speed is slow – 6-30 feet per day, the danger consists in the depth of fire spreading to the mineral soil, which significantly complicates the process of extinguishing).
