Which advantage is associated with in situ nurseries for coral restoration?

In situ nurseries are advantageous for coral restoration primarily due to their lower operational costs compared to other methods. Utilizing natural habitats for growing corals allows for a more cost-effective approach. In situ nurseries leverage local resources, such as substrate and water quality, minimizing the need for extensive infrastructure or artificial systems that can drive up expenses.

The use of in situ nurseries also means that transportation and logistics costs related to moving corals are significantly reduced, as the corals are grown in their natural environment. This practical approach not only helps in saving money but also promotes better acclimatization of coral species to their native conditions, enhancing their chances of survival when outplanted.

Other options may suggest benefits related to advanced technology or specially managed environments, but these aspects often involve greater complexity and expense, making in situ methodologies more appealing for budget-conscious restoration projects.
