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
