What is one key consideration when selecting a nursery site for coral restoration?

One key consideration when selecting a nursery site for coral restoration is the need for protection from disturbances. Coral nurseries are vulnerable to various environmental and anthropogenic factors such as storm surges, pollution, and human activity that can negatively impact coral growth and survival. By choosing a site that is shielded from these disturbances, the likelihood of successful coral cultivation and eventual outplanting increases significantly. This protection allows for a more stable environment, which is crucial for the development and resilience of coral species being grown in the nursery.

The other options, while relevant to some degree in certain contexts, do not address the primary requirements for a successful coral nursery. For instance, ease of transportation might facilitate logistics but does not necessarily contribute to the health of the corals. Similarly, proximity to urban areas could pose a risk of increased pollution or human interference, rather than ensuring a safer growing environment. The size of coral species could relate to specific growth needs or compatibility with the nursery environment, but it is less critical compared to the essential requirement of reducing disturbances to promote healthy coral growth.
