Which of the following describes the BACI design in coral restoration?

• A. It assesses the financial impact of restoration efforts
• B. It compares control sites with reference sites over time
• C. It focuses solely on recruitment success
• D. It is a method for random sampling

Answer: (B)

The BACI design stands for "Before-After Control-Impact" and is a well-established method used in ecological studies, including coral restoration. This approach is particularly valuable because it allows researchers to evaluate the effects of restoration efforts by examining changes over time at both impacted and non-impacted (control) sites. In the BACI design, scientists first gather baseline data from both control and impact sites before restoration efforts are implemented. After the intervention, they continue to monitor these sites. By comparing the changes at the control sites, which are unaffected by restoration, to those at the impact sites, researchers can better isolate the effects of the restoration activities from other environmental changes. This longitudinal analysis helps to attribute observed differences directly to the restoration efforts, thus providing a clearer understanding of their effectiveness. Other choices do not accurately reflect the nature of the BACI design. For instance, evaluating financial impacts, focusing solely on recruitment success, or utilizing random sampling methods do not address the essential comparative aspect that characterizes BACI. This design is specifically concerned with environmental impacts over time at different sites, making the comparison of control and impacted areas key to understanding coral restoration outcomes.
