Forest fire occurs mainly due to the combination of three elements, which are oxygen, fuel, and heat. On a typically hot day, the forest becomes dry. So, even a tiny spark can cause a large fire with catastrophic consequences. They are often caused as a result of human carelessness. Natural causes such as lightning strikes are also responsible for such wildfires. However, there are many benefits to Forest Fires too. We can find many ecosystems that require the destructive flames of forest fire in order to function properly.
The various benefits of forest fire are:
Clearance Of The Clutter Is One Of The Many Benefits Of Forest Fires
Forest fire is a great way of clearing the clutter. The burning plants and other debris such as leaves, old logs and thick undergrowths carry lots of nutrients and minerals. The fire breaks them down. Moreover, they are absorbed in the soil and make the forest floor increasingly fertile. Therefore, the amount of nutrients in the soil increases and it makes a perfect condition for the survival of the microbial lives on the forest floor.
Wipes Out Weeds And Infection
Forests are often invaded with deadly weeds that spread infections and life-threatening diseases to plants and other inhabitants. However, the blazing flames of the forest fire wipe out these invading weeds that affect a particular site. Therefore, it renders a chance for a fresh start and the re-growth of the native species.
Birth Of New Grasslands Is One Among The Many Benefits Of Forest Fires
The wildfires of forests often result in the creation of new grasslands. Therefore, in this way, it maintains the ecosystem. The fire buries the woody plants and lets the green grass grow. It helps in shaping the overall makeup of the vegetation. Moreover, the fire moves through the grassland at a rapid speed and most grasses have the capacity to tolerate fire. It also keeps a check on the excessive growth of the shrubs and trees that take over grasslands and converts into the forest. The non-native vegetation spreads at an alarming rate and stunts the growth of the fresh species. The creation of new grasslands also benefits the different species of grazing animals. The natural order of the food chain within the ecology also adapts to the new ecology.
Creation Of New Life
There are many species that springs to life and make use of the newly available nutrients right after a forest fire. Fireweeds are responsible for bringing new shades of color to the barren grey landscape of the burnt forest. They also play a vital role in introducing vegetation in a burnt site. Moreover, the seeds stay absorbed in the soil. They wait for a new ignition to open up space and the light enters that renew the germination. However, there are also certain species like Pigmy pitch pine that sprouts from the trunk of a damaged and burnt tree trunk. Aspen, alder, and birch also grow from the stumps and roots of burnt trees.
