Highest Coral Cover in Central and Northern Reef in 36 Years
The Great Barrier Reef, the world's largest coral reef system, has been facing a significant decline in coral cover over the past few decades. However, recent studies have shown that there has been a significant increase in coral cover in the central and northern regions of the reef. This is the highest coral cover recorded in these regions in 36 years.
Introduction
The Great Barrier Reef is one of the most diverse and complex ecosystems on the planet. It is home to thousands of species of marine life, including corals, fish, sharks, turtles, and whales. However, over the past few decades, the reef has been facing significant threats due to climate change, pollution, and overfishing. One of the most visible impacts of these threats has been the decline in coral cover.
What is Coral Cover?
Coral cover refers to the percentage of a reef that is covered by living coral. Coral reefs are made up of millions of tiny animals called polyps that secrete calcium carbonate to form a hard skeleton. These skeletons accumulate over time to form massive structures that provide habitat for a wide range of marine life.
The Recent Study
According to a recent study published in the journal Coral Reefs, there has been a significant increase in coral cover in the central and northern regions of the Great Barrier Reef. The study was conducted by researchers from the Australian Institute of Marine Science (AIMS) who surveyed 127 reefs across the length and breadth of the Great Barrier Reef.
Findings
The study found that coral cover had increased from 14% in 2017 to 25% in 2021 in the central region of the reef. In the northern region, coral cover had increased from 22% in 2017 to 33% in 2021. These are the highest levels of coral cover recorded in these regions in 36 years.
Reasons for the Increase
The increase in coral cover can be attributed to a combination of factors. One of the most significant factors is the reduction in the frequency and severity of coral bleaching events. Coral bleaching occurs when corals expel the algae that live inside them, causing them to turn white and eventually die. This is caused by high water temperatures, which are a result of climate change.
Another factor that has contributed to the increase in coral cover is the reduction in crown-of-thorns starfish populations. These starfish are known to feed on coral and can cause significant damage to reefs.
Conclusion
The increase in coral cover in the central and northern regions of the Great Barrier Reef is a positive sign for the future of this iconic ecosystem. However, it is important to note that there are still significant threats facing the reef, including climate change, pollution, and overfishing. It is crucial that we continue to take action to address these threats and protect this unique and valuable ecosystem for future generations.
FAQs
