Forest ecosystems are subject to the actions, often negative, of external biotic or abiotic factors, and are forest fires are among them.
Vegetation fires can cause air pollution in the areas where they occur. Thus, they can induce the production of carbon, which causes an increase in the amount of carbon dioxide. It also promotes air pollution with suspended particles, especially fine particles. An increased level of combustion products in the troposphere can raise ozone levels beyond safety limits.
Other adverse effects of forest fires on the eco system:
The problem of fires is much more subtle than anyone would think. Forest fires have always existed in the history of the Earth. Very little is known about the place and role of fires in ecology, climatology, paleoecology and other fields. Experts say that there is an increased risk of wildfires due to climate changes. The fossil coal discoveries indicate that forest fires are not specific to modern history, but date back more than a hundred million years. It seems that the Earth is a naturally flammable planet because of the oxygen in the atmosphere, the vegetation rich in carbon, dry climates, and volcanic activities - among others.
Today, however, over 90% of forest fires are caused by people, either from accidents, negligence or intentionally caused. When you own property that is in heavily forested areas it's best to have a tree service company out to do fire mitigation to help prevent fires near your home.
Top 5 causes of forest fires in Colorado are:
1. burning of vegetal residues
2. randomly discarded cigarette butts
3. children's play with fire
4. irresponsible use of open fire
5. premeditated arson
To all these causes, the unfavorable weather conditions contribute decisively (wind direction and speed, drought, high temperature and low air humidity), as well as the characteristics of the vegetation, which will may allow fires to spread more or less quickly.
Authorities in Colorado launch periodic fire awareness campaigns, in their attempt to reduce human incidents that cause them.
Unfavorable weather conditions, represented by the simultaneous combination of extremely low air humidity and very high ambient temperatures or electrical discharges, in the presence of a fuel such as dry vegetation can trigger a natural fire. People and their negligence or bad intentions represent another major cause that can lead to the outbreak of a vegetation fire: a cigarette bud thrown away, indiscriminate use of pyrotechnic materials or even deliberate arson.
Elements that may increase the risk of a wild fire:
Fourth of July is unimaginable without parties and traditional fireworks. Unfortunately, even though we may not like to admit it, this type of entertainment can often be the cause of major problems, such as forest fires.
Many people prefer to believe that fireworks have a very low risk of starting fires, which is somewhat true, in the case of controlled fireworks. But let's not forget all the partygoers who use Fourth of July pyrotechnic devices, without questioning their quality or safe use. In addition, there is the danger of cigarette buds thrown away irresponsibly and unattended campfires.
So, if you have a forested property, you should be extra careful this Fourth of July. The smoke produced by the fires affects human health, causing diseases of the eyes, skin and respiratory system, not to mention their potential to destroy flora, fauna, as well as private properties. An ember propagated by vegetation on a forested private property can ignite, in a very short time, the house and household outbuildings.
If you are a forested property owner, make sure you consider wildfire mitigation services and have tree removal done if necessary, to minimize the risks related to the destructive effects that a wildfire may have on your property.
