Australian forests burned. Several hectares of forest have been burning for weeks. Deliberate fire set forest areas on fire. The hot wind took the life of the forest and its creatures. The Hyrcanian forest fire was extinguished after burning several hundred hectares. Titles that make us upset hearing and thinking, we can really do something or not?!
To answer this question, we must first have information about the fire.
Forest fires are an uncontrollable type of fire. Its uncontrollability is due to the ignition of plants. High ignition and wind, scattering, and thus the spread of fire. If we consider the issue of fire in terms of region and climate, Australia is a hot and dry region where the outbreak of fire is not unexpected! But for years, due to climate change, fires have become an integral part of forests. It is not bad to know that forest fires are also referred to as creating fires in meadows and groves, bushes, and swampy soils. In fact, forest fires are called wildfires in nature.
Forest fires can occur for a variety of reasons, depending on the cause, strength, and rate of spread. Of course, in all cases, timely presence and information can be effective. The following are the types of fires.
Superficial fires are the kind we deal with more than any other type. The fire of grasses usually causes it, and of course, due to the lightness of the grass, its contagious power should not be underestimated. Climate change has also created a rare type of fire that causes rotten forest soil to dry out and catch fire. This type of fire can also be critical.
This type of fire causes a lot of damage to young seedlings and may even burn the collars of larger trees. The collar is the part of the tree that is in contact with the soil. Cheeks such as thin-skinned beeches can be fatally damaged. Because there is a layer between the woody vessels and the thin skin of the beech, which is responsible for delivering nutrients to the top. By shedding the skin, that layer is exposed to damage and the feeding is cut off and the main trunk is damaged.
This type of forest fire can turn into a solitary and crown fire when strong winds blow, which we will explain below.
Another type of forest fire is solitary fire. This species occurs directly in the forest. A tree trunk or even a dry trunk may catch fire. Empty trees or trees that have turned into pieces of wood are prone to this type of fire. This fire has the shape of a stove, like the wood you throw in the fireplace and it draws fire inside!
Imagine a tree that burns from the collar and falls to the ground on a forest slope. Not only does his body catch fire, but everything in its path catches fire. The pieces are detached from the trunk and thrown to each corner, and the fire spreads to other parts.
The third type of forest fire is the crown fire. Coronary fires are common in forests with coniferous pines. Due to the high content of resins as a flammable material in these forests, the speed and probability of fire are higher. In broad-leaved forests, there is a possibility of fire due to the presence of dry and semi-dry trees in the middle steppes. When a superficial fire occurs and spreads to the trunk, there is also the possibility of the crown burning, and this type of fire usually completely destroys the tree.
There is a phenomenon in the world called controlled fire or prescription fire! Yes, do not be surprised. This type of fire, as its name implies, is planned to achieve the following goals:
Every few years, by following special principles and methods and providing advanced tools for extinguishing and controlling fires, the forest is burned to achieve the goals we have listed. All conditions such as temperature, fuel time and humidity, amount of fuel, wind direction and speed, and topography of the area must be considered. Fire is created around the area.
This usually happens at the beginning of the summer season. When the ground is not yet completely dry and flammable materials are wet. This usually happens from 6 pm to 10 am. Of course, because fire control is much more difficult at night, it may sometimes only run early in the morning, depending on team skills and facilities.
In the last hours of the day, high temperatures due to temperature fluctuations can take the fire out of control. Unfortunately, there are various examples in the world where fires are out of control and the whole forest is lost.
In this article, you will get acquainted with different types of fires. There are reasons for the fire in the Hyrcanian forests, which we will discuss in the next article. It is interesting to know that fire does not only have the disadvantages that are talked about and sometimes even the advantages.
