The Importance of Crown-of-Thorns Starfish Control on the Great Barrier Reef
The Great Barrier Reef, one of the most iconic natural wonders on Earth, has been facing numerous threats in recent years, including coral bleaching, cyclones, and the proliferation of crown-of-thorns starfish. This commentary aims to shed light on the significant benefits of crown-of-thorns starfish control on the Great Barrier Reef, as revealed by a recent study published in the journal PLOS ONE.
Understanding the Threat of Crown-of-Thorns Starfish
Crown-of-thorns starfish, while native to the Great Barrier Reef, can pose a serious threat to coral health when their populations explode into outbreaks. These outbreaks can result in widespread coral loss and reef degradation, exacerbating the already existing pressures on the reef ecosystem. The recent research highlighted in the study led by the Reef Authority underscores the importance of targeted control efforts to mitigate the impact of these outbreaks.
The Positive Impact of Control Efforts
The study demonstrated a remarkable up to six-fold reduction in crown-of-thorns starfish numbers and a 44% increase in coral cover in regions where timely and sufficient control efforts were implemented. This significant improvement in coral cover not only protects the reef ecosystem but also enhances its resilience in the face of ongoing environmental challenges such as climate change. The success of the control program is credited to targeted surveillance and culling, which have proven to be effective, efficient, and scalable management actions critical for the long-term health of the Great Barrier Reef.

Collaborative Efforts for Conservation
The success of the crown-of-thorns starfish control program is a testament to the collaborative efforts of various stakeholders, including researchers, reef managers, and conservation organizations. By combining data from the Crown-of-thorns Starfish Control Program and the Australian Institute of Marine Science’s Long-Term Monitoring Program, researchers were able to gain valuable insights into the effectiveness of the control measures. This integrated approach has not only helped in protecting coral reefs but has also contributed to the preservation of vital habitats for marine creatures, supporting the biodiversity of the Great Barrier Reef.
The findings of the study underscore the critical importance of crown-of-thorns starfish control in safeguarding the health and resilience of the Great Barrier Reef. By implementing targeted control efforts, reef managers can effectively suppress outbreaks of the coral-eating starfish and protect coral reefs on a large scale. As climate change continues to pose a significant threat to the reef, proactive conservation measures such as the control of crown-of-thorns starfish are essential for ensuring the long-term survival of this invaluable marine ecosystem.

Crown-of-thorns starfish
The crown-of-thorns starfish (frequently abbreviated to COTS), Acanthaster planci, is a large starfish that preys upon hard, or stony, coral polyps (Scleractinia). The crown-of-thorns starfish receives its name from venomous thorn-like spines that cover its upper surface, resembling the biblical crown of thorns. It is one of the largest starfish...

Coral bleaching
Coral bleaching is the process when corals become white due to loss of symbiotic algae and photosynthetic pigments. This loss of pigment can be caused by various stressors, such as changes in temperature, light, or nutrients. Bleaching occurs when coral polyps expel the zooxanthellae (dinoflagellates that are commonly referred to...
