Which of these is NOT a primary aspect of ecological monitoring in coral restoration?

Ecological monitoring in coral restoration typically focuses on assessing the health and recovery of coral populations and their immediate environment, which is reflected in the other options. Juvenile coral abundance is crucial as it indicates recruitment success and the potential for future population growth. Live tissue percentage is a direct measure of coral health, as it shows the proportion of living coral tissue compared to dead or damaged areas, which is essential for understanding coral resilience. Species-specific coverage provides insights into biodiversity and community composition, aiding in the evaluation of the ecosystem's overall health and ecological balance.

The abundance of reef users may not directly pertain to the primary goals of monitoring coral restoration, as it focuses more on the ecological aspects of the coral itself rather than the broader impacts and interactions within the ecosystem. While reef users can influence coral health, their abundance is not a primary metric used to assess the corals' recovery and resilience directly. This makes it distinct from the other options, which are integral to understanding coral ecology and restoration success.
