Which of the following is a common challenge in coral restoration efforts?

In coral restoration efforts, a significant challenge presents itself in the form of invasive species that threaten coral health. Invasive species often outcompete native corals for resources such as space and nutrients, leading to a decline in the health and diversity of coral ecosystems. These non-native species can disrupt the local marine environment, making it difficult for restored coral populations to thrive. The introduction and spread of such species can result in altered dynamics within the ecosystem, further complicating restoration efforts.

While other factors, such as high costs of restoration techniques, might pose challenges, the direct and prevalent threat of invasive species is particularly critical because it affects the very foundation of coral ecosystems. The presence of invasive species can hinder recovery processes and limit the success of restoration initiatives. Therefore, addressing the impact of invasive species becomes essential in achieving effective and sustainable coral restoration.
