Which restoration technique involves replanting an area with native vegetation?
Explanation: The correct answer is A) Reforestation. Reforestation is a restoration technique that involves replanting an area with native trees and vegetation. It is often used to restore deforested or degraded land, such as clear-cut forests or abandoned agricultural fields. Reforestation helps to rebuild the forest ecosystem, enhance biodiversity, improve soil health, and provide various ecosystem services.
Which restoration technique aims to control the spread of invasive species?
Explanation: The correct answer is A) Biological control. Biological control is a restoration technique that aims to control the spread of invasive species. It involves the introduction of natural enemies, such as predators, parasites, or pathogens, to reduce the population of invasive species. By targeting the invasive species specifically, biological control helps to restore the balance of the ecosystem and protect native species and habitats from the negative impacts of invasions.
Which restoration technique involves the construction of artificial ponds or wetlands?
Explanation: The correct answer is A) Wetland creation. Wetland creation is a restoration technique that involves the construction of artificial ponds or wetlands. It aims to restore or create wetland ecosystems, which are important for water filtration, flood control, habitat provision, and biodiversity conservation. Wetland creation typically involves shaping the landscape, creating appropriate hydrological conditions, and planting native wetland vegetation.
Which restoration technique is used to stabilize eroding riverbanks or shorelines?
Explanation: The correct answer is A) Streambank stabilization. Streambank stabilization is a restoration technique used to prevent or reduce erosion along riverbanks or shorelines. It involves the implementation of measures, such as the installation of erosion control structures, planting native vegetation, and modifying the flow of water, to stabilize the banks and prevent further erosion. Streambank stabilization helps to protect aquatic habitats, maintain water quality, and prevent the loss of valuable land.
Which restoration technique involves the removal of contaminants or pollutants from soil or water?
Explanation: The correct answer is A) Phytoremediation. Phytoremediation is a restoration technique that involves the use of plants to remove or neutralize contaminants or pollutants from soil or water. Certain plant species have the ability to absorb, break down, or transform various pollutants, such as heavy metals or organic compounds, through their root systems or metabolic processes. Phytoremediation offers an eco-friendly and cost-effective approach to environmental cleanup and restoration.
