Techniques for Restoring Degraded Habitats MCQs What is the main purpose of reforestation in habitat restoration? To restore native tree cover and ecosystem functions Which technique is commonly used to restore wetlands? Reestablishing natural hydrology Which method is used to prevent soil erosion in degraded habitats? Terracing and contour plowing What is the purpose of using bioengineering in habitat restoration? To stabilize soil using natural materials like plants and roots Which of the following is a technique used to control invasive species? Manual removal or chemical treatment What role do buffer zones play in habitat restoration? They protect restored areas from adjacent land-use impacts How does the process of natural regeneration work in habitat restoration? Allowing native species to recolonize an area without human intervention Which technique involves the introduction of native species into restored habitats? Rewilding What is a key challenge when using revegetation techniques in drylands? Water scarcity and harsh climate conditions Which method is often used to restore degraded river ecosystems? Streambank stabilization How does mulching help in habitat restoration? It reduces soil erosion and conserves moisture What is the role of controlled burns in habitat restoration? To reduce invasive species and promote native plant growth Which method is typically used to restore coastal habitats? Dune restoration and planting native vegetation What is the purpose of soil amendments in habitat restoration? To improve soil fertility and structure for plant growth Which technique involves creating barriers to control water flow and prevent erosion? Check dams What is the primary goal of coral reef restoration? To enhance biodiversity and restore marine ecosystems How does grazing management contribute to habitat restoration? It controls overgrazing and promotes plant recovery Which practice is used to restore prairie habitats? Planting native grasses and controlled burning How does the removal of dams aid in river habitat restoration? It restores natural flow and fish migration routes Which of the following is a technique for restoring degraded grasslands? Sowing native grasses and controlling invasive species What is a key method for improving degraded soils in agricultural lands? Crop rotation and cover cropping How can fencing be used in habitat restoration? To exclude grazing animals and allow vegetation recovery What is the role of artificial reefs in marine habitat restoration? To provide structure for marine life colonization Which technique involves using plants to remove contaminants from soil? Phytoremediation How does sediment trapping help in wetland restoration? It rebuilds soil layers and promotes vegetation growth What is the benefit of using green infrastructure in urban habitat restoration? It reduces stormwater runoff and creates wildlife habitat Which practice is essential in the restoration of mangroves? Replanting mangroves and restoring tidal flow What is the role of seed banks in habitat restoration? To preserve native plant species for future reintroduction Which method is commonly used to restore degraded forests? Planting a mix of native tree species How do biological corridors assist in habitat restoration? They connect fragmented habitats, allowing wildlife movement Which technique is used to restore seagrass beds in marine environments? Transplanting seagrass plugs into degraded areas What is a common method to enhance pollinator habitats in restoration projects? Planting native flowering plants that attract pollinators How do artificial wetlands function in habitat restoration? They treat wastewater and provide wildlife habitat What is the purpose of removing invasive species in habitat restoration? To allow native species to reestablish and thrive How does contour plowing contribute to soil restoration? It reduces soil erosion on slopes by following natural contours Which technique is used to restore fish populations in degraded rivers? Restocking native fish species and improving habitat conditions What is the role of composting in soil restoration? It adds organic matter and nutrients to degraded soils How does restoring natural fire regimes benefit certain ecosystems? It helps maintain biodiversity and control invasive species Which of the following is a method used to restore degraded peatlands? Blocking drainage channels to raise the water table How does reintroducing keystone species aid in habitat restoration? They play a crucial role in maintaining ecosystem structure and balance Which technique is commonly used to restore oyster reefs? Deploying artificial structures for oyster settlement What is the primary goal of riparian buffer restoration? To protect waterways from pollution and erosion How can livestock exclusion contribute to the recovery of degraded habitats? It allows native vegetation to recover without grazing pressure What is the purpose of using cover crops in degraded agricultural lands? To prevent soil erosion and improve soil health Which technique helps restore degraded sand dunes in coastal areas? Planting native dune grasses to stabilize sand How does watershed management support habitat restoration? It ensures sustainable water use and reduces erosion What is the goal of using bioremediation in habitat restoration? To break down pollutants using microorganisms How does the restoration of tidal flow benefit coastal wetlands? It improves water quality and promotes native species recovery
