When the first settlers arrived in North America, they used small fire extinguishers for their own purposes make the environment more productive. But with the whites, and later the spread of homes and factories in the West, came the idea of reducing fires: To protect lives and property, wildfires should be extinguished as soon as possible. In the arid rain forests of West America, without much of the world’s small-scale rehabilitation efforts, this has resulted in dangerous fossil fuels.
Consider the area around the town of Cranbrook in southeastern British Columbia. Before the fire stopped, its forests were mainly ponderosa pine and Douglas fir, probably less than 50 trees per hectare. The region was hit by a devastating wildfire seven years later. Any low-level fire that burns grass, bushes, and wood waste can save many trees, while still destroying humanity.
But thanks to fire suppression, there are now 10,000 trees per hectare, 95% of which are Douglas firs. Without the right firewood fixed to trees, the species began. “This is a unique example of the fact that, if you remove a fire from the system, you can drastically change the species and its structure – in particular, its quantity,” says Gray. Since the trees are now very crowded, fires can spread between them and travel through the area. To make matters worse, he says, with more than 200 trees per hectare here now, “it would not be a burning fire,” he continues, or that has a significant impact on ground berries. “It will be a great reward, and it will kill everything.” In a blazing fire, the flames spread between the tops of the trees.
Due to this combination of fossil fuels and the lack of natural fires, the area cannot be “adequately protected”. And both plants and animals do not really prepare for this kind of fire. “Fires are very hot, and the species of animals that live in them are probably not the same as such heat,” says Gray. “And if a fire is occurring in a large area, it will be difficult for them to reopen the area.”
When a forest is destroyed, it causes problems that last for years. The rest of the animals will not hide hiding enemies. The increased heat is also absorbed by the destructive species, especially the beneficial weeds, whose seeds begin to sprout from nearby areas. Once it has stabilized, it releases all kinds of reactions that try to get back on the wound. “They really use these conditions,” says Gray. “And they can change the vegetation environment by making it simpler, more compatible.”
So how do you know if a wildfire was “good” or “bad” on the spot? Calculating prices via satellites, drones, and planes. With a small fire, prices as low as 20% will die. For fires, it is more than 80 percent. The degree of damage may vary slightly on one fire: The edges may be hotter than the inside, or vice versa. Growing up is another matter. “If its patch is big enough, especially the forest should re-emerge at its edges,” says Gray. “If there is a 50,000-hectare fire, it is a long way to rehabilitate forests.”
Wildfires also study how the soil works and how it is made to determine the origin of the fire. The presence of red iron oxide, for example, indicates that wildfires have consumed more fires. If the scientists found that the roots and the buried plants survived well, then I was showing a slightly burning fire.
