Different climatic factors and rapid industrialisation have caused a risk to the natural ecosystem. Soil deterioration, deforestation, and loss of biodiversity have become significant challenges. Many conservationists and environmentalists recommend revegetation to restore the ecosystem and degraded landscapes.
Understand the concept of revegetation-
Revegetation is a way to restore the soil in the disturbed land. The major purpose is to avoid soil erosion and facilitate more water absorption during heavy rainfall. Sometimes, construction works and the pressure of heavy vehicles disturb or damage the plant cover of an area. Vegetation suitable to that place needs to be re-established with the revegetation process. Thus, revegetation converts a degraded area to a better condition.
Why is revegetation beneficial to the soil and environment?
Revegetation is different from the normal act of planting trees. You need to make a pre-plan of the plants you will grow in the area. So, analysing the landscape and environmental factors is essential for effective revegetation. With a proper plan, you can allocate the resources efficiently. Revegetation is important for multiple reasons:
Control soil erosion-
If the land is bare, it increases the risk of erosion. Thus, plants will reduce the soil erosion level by creating a protective barrier. They slow down water overflow and allow rainwater to get absorbed into the ground. The plant’s roots also stabilise embankments and lower the risk of landslides.
Plants, big trees, and even crop residue provide soil coverage. Mulching also establishes vegetation and prevents destructive erosion.
Ensure conservation-
Restoring the natural habitat is another reason behind revegetation. It helps in protecting bird species and preserving natural diversity. So, when you plan new vegetation, you should consider existing habitats. If it is an agricultural site, revegetating will encourage breeding.
Reduce pollution-
Reforestation and revegetation can minimise the pollution level. Deforestation increases the percentage of carbon dioxide in the air. Thus, you can consider revegetation to reduce the carbon buildup. Mature trees help in controlling the carbon dioxide level in the air.
Restore soil fertility-
Mining and other similar activities may cause damage to topsoil. The rate of soil erosion increases due to these activities. Other common risks are the loss of soil structure, reduced soil pH, and depleted organic matter. Proper management of topsoil reduces the nutrient loss and maintains fertility.
Revegetation allows the soil to improve the potential to exchange cations and sustain biological activities. Legumes and grasses are best for revegetating the land of mined areas.
Make the landscape more aesthetic-
Vegetation not only filters pollutants from the air but also adds beauty to the environment. A bare land regains its attractiveness when you grow plants on it. Even a small yard looks lifeless if there are no plants. So, vegetation makes the property look more colourful.
To conclude, revegetation is a way to reintroduce native vegetation to a particular area, which has once experienced disruption. Besides, protective plastic tree guards help you secure new plantings against wind damage, bugs, and animals. You may also consult an expert for your revegetation project.
