Critically Endangered (Population stable)
Staghorn coral/Conservation status

Why are staghorn corals declining?

Particularly susceptible to bleaching, staghorn coral populations have declined more than 80 percent over the past 30 years due to higher incidence of disease and the impacts of global warming, especially higher ocean temperatures and ocean acidification, according to the International Union for the Conservation of …

What are the two biggest threats to coral reefs?

Increased ocean temperatures and changing ocean chemistry are the greatest global threats to coral reef ecosystems.

Why did the population of staghorn corals increased?

Staghorn corals highlight the impacts of rising sea temperatures and increasing ocean acidification due to climate change. Staghorn corals are thought to have evolved in the late Paleocene some 55-65 million years ago, and have dominated many reefs for the past 500,000 years.

Is staghorn coral found in the Great Barrier Reef?

About a quarter of all coral species on the Great Barrier Reef are staghorn corals, and they provide much of the three-dimensional structure fishes and many other coral reef animals rely on, just like trees in a forest.

Why are staghorn corals so fragile?

Staghorn Coral is listed as Critically Endangered on The IUCN Red List of Threatened Species. Climate change and the associated rise in sea temperature is the biggest threat to Staghorn Corals as changes in temperature can cause bleaching – when corals expel their zooxanthellae into the water column.

Is staghorn coral hard or soft?

There are two main types of corals: hard corals and soft corals. Hard corals, like elkhorn coral and staghorn coral, grow in colonies and are often referred to as “reef-building corals.” Hard corals create skeletons out of calcium carbonate, a hard substance that eventually becomes rock.

Why are the coral reefs dying?

And they are dying. Coral reefs are under relentless stress from myriad global and local issues, including climate change, declining water quality, overfishing, pollution and unsustainable coastal development.

Which coral reefs are most threatened and why?

Key Findings. Coral reefs of Southeast Asia, the most species-rich on earth, are the most threatened of any region. More than 80 percent are at risk, primarily from coastal development and fishing- related pressures.

What is the most common coral in the Great Barrier Reef?

Staghorn variety
The most common type of hard coral found in the Great Barrier Reef is the Staghorn variety, which over time forms limestone casings that become an important building block in the reef’s expansion providing a safe habitat for its many ocean-dwelling creatures to live in.

Why is coral important to the Great Barrier Reef?

They: protect coastlines from the damaging effects of wave action and tropical storms. provide habitats and shelter for many marine organisms. are the source of nitrogen and other essential nutrients for marine food chains.

Why did corals declined since 1977?

Coral and fish communities showed dramatic declines from 1977 to 1996 due to massive harbor construction and suboptimal land management practices on the watershed. More recently, corrective measures in the form of watershed stabilization and fishing regulations have been implemented.

Why are staghorn corals important to the environment?

This loss can lead to coral death through starvation or increased vulnerability to diseases. Due to their bush-like growth form, staghorn corals provide complex habitat for fish and other coral reef organisms. When staghorn corals are abundant, they provide shoreline protections from large waves and storms.

What is the symbiotic relationship between a staghorn coral and its algae?

Like many corals, Staghorn Corals have a symbiotic relationship with single-celled algae called zooxanthellae, which live in the polyp tissues. They produce nutrients through photosynthesis which they then pass to the corals. These nutrients are their primary food source, but Staghorn Corals also prey on microscopic…

How big do staghorn coral branches get?

Branches are typically 1 to 3 inches thick. Individual colonies can grow to at least 4 feet in height and 6 feet in diameter. Staghorn coral colonies can grow in dense stands and form an interlocking framework known as thickets. Each staghorn coral colony is made up by many individual polyps that grow together.

Do fish eat staghorn corals?

It’s also not uncommon for certain species of fish, such as parrotfish, to bite off parts of the coral to reach prey hiding within. What are the biggest threats to Staghorn Corals? Staghorn Coral is listed as Critically Endangered on The IUCN Red List of Threatened Species.
