The Importance of Coral Reefs
Coral reefs are essential to marine ecosystems and are critical for the health of the ocean (González-Barrios et al., 2021). Despite covering less than 1% of the ocean floor, coral reefs support around 25% of global marine biodiversity (Hughes et al., 2023; Voolstra et al., 2023). There are several interconnected factors in coral reef ecosystems, such as water quality, coral distribution, coral recruitment, fish, and the diversity and quantity of large benthic organisms that form an interdependent ecological network (Hempson et al., 2018). Water quality is a significant factor affecting coral health, distribution, and recruitment, considering temperature, salinity, and nutrient levels (Woods et al., 2016). Excellent water quality is vital for the successful settlement and growth of juvenile corals (Cruz and Harrison, 2017). Coral cover and recruitment rates are crucial indicators of coral reef health (Harrison et al., 2021). Therefore, understanding the distribution and recruitment of corals in different regions provides valuable insights into the reproductive capacity and recovery potential of coral reefs. The abundance and diversity of fish and macrobenthic organisms are also essential for maintaining the balance and functionality of coral reef ecosystems (Massei et al., 2023).
Threats to Coral Reefs
Coral reef ecosystems face multiple threats from climate change, overfishing, pollution, and habitat destruction (Ruppert et al., 2018). Rising sea temperatures from global climate change result in coral bleaching, impacting coral survival and reproductive capacity (Figueiredo et al., 2022; van Woesik et al., 2022; Nama et al., 2023). Additionally, human activities, such as overfishing and pollution, have immediate impacts on coral health (Cramer et al., 2020). Overfishing disrupts the balance in coral reef ecosystems, while pollution introduces toxic substances that disrupt the entire coral ecosystem (Blanckaert et al., 2023). Furthermore, tourism and marine recreation activities can unintentionally harm coral reefs, creating an immediate threat (Worachananant et al., 2008; Tashiro and Kameda, 2013).
At Hainan Island, the rich fringing reefs near the coastline have decreased by at least 80% over the past 30 years (Huang et al., 2020). The Qiziwan National Marine Park (QZW), a tourist attraction on the west coast of Hainan Island in China, is known for its abundant coral reef resources and calm bay waters. However, it is at the risk of degradation due to nearby ports and their dredging activities, which render coral reef ecosystems vulnerable in coastal desertification landscapes.
