Pillar of Hope

As recreational divers, we are driven by the desire to explore the vast 71% of our planet that is covered in water. Every time we descend below the surface, we are presented with an opportunity to delve into a new ecosystem. Among the most beloved ecosystems worldwide are tropical reefs, which only occupy a small 1% of the Earth's surface but support over 25% of marine biodiversity. The reason behind this astonishing fact is that corals serve as habitats for an immense variety of organisms, ranging from fish to invertebrates, many of which have yet to be fully documented and described.

South Florida is home to one of the largest reef ecosystems in the world.

One of the largest coral reef ecosystems in the world can be found just off the coast of Florida in the United States. This reef serves as a habitat for thousands of species that rely on a specific subset of stony corals, which are vital for the reef-building process. Despite being simple organisms, these corals form a living tissue layer that covers the surface of the reef, protecting bioerosion caused by other organisms and natural processes. One example of an organism that contributes to the bioerosion of reef structures is sponges. While sponges create three-dimensional structures during their lifespan, they are unable to accumulate reef material beyond their lifetime and can contribute to the degradation of existing calcium carbonate structures.

Can you distinguish which is a Coral and which is a Sponge?

The pillar coral is renowned for its distinctive large shape, as well as its tentacles that gracefully sway in the ocean currents. Unfortunately, this coral species is highly susceptible to various stressors, including diseases that have severely impacted its population in recent years. In the image, you can observe the limited surviving living tissue at the top, representing the remnants of what used to be a thriving and sizable pillar coral colony.

The living tissue of the pillar coral plays a crucial role in safeguarding the underlying calcium carbonate from bioerosion. Despite being rare in present times across Florida and the Caribbean, pillar corals were once significant reef-building organisms. They now serve as a poignant reminder of the pressing need to take immediate action to protect these corals and the reefs they construct. Not only are these corals vital members of the ecosystem, but they also play a pivotal role in maintaining coastal development for human communities.

Without prompt action to alter our interactions with coastal ecosystems, magnificent and iconic corals like these could soon become remnants of the past. It is our responsibility to preserve the integrity of these ecosystems, fostering a habitat that sustains life beyond our species.

How can you help make a difference on our reef?

There are many ways to contribute to the protection of our reef ecosystems from choosing sustainable products, using chemical-free sunscreens, and diving with operators who put conservation and sustainability at the forefront of their mission.

Let’s start with some of the easiest ways you can take action and help protect our coastal coral reef environments.

  • Use environmentally friendly sunscreens

  • Don’t anchor near corals

  • Avoid touching corals while diving or snorkeling.

Now let’s get specific, Divers what can we do better to protect the environment we love so much?

  • Buoyancy. Buoyancy is a key factor in diving and having good buoyancy cannot be stressed enough. Before diving a reef be sure you are aware of your weight needs even if that means going to a place like the Blue Heron Bridge to determine what you need. This will help you avoid damaging the fragile reef habitat.

  • Help clean the reef by removing debris you find along the reef. Carrying a small mesh bag can be invaluable while out diving.

  • No dangly bits. Sure you mare have great buoyancy but if you have your flashlight, second stage, or muck stick dragging across the reef below you it is a moot point.
