Hawaii’s Coral Reefs: Benefits, Threats, Types, Preservation

Think of Hawaii’s coral reefs like an underwater garden. They are a breathtaking mix of vibrant colors and life, providing essential habitats for marine creatures as well as a source of food and income for humans.

Unfortunately, these exquisite ecosystems are facing serious threats from pollution, global warming, and overfishing.

This article will examine the importance of Hawaiian coral reefs, their current state, and what can be done to protect them. So come along on a journey beneath the waves and explore the beauty of Hawaii’s precious coral reefs!

Benefits of Coral Reefs

Coral reefs are extraordinary habitats, and the ones found in Hawaii are no exception. You can find them along the coastlines, providing a home to nearshore fisheries, protecting coasts from waves and storms, and supporting the local tourism and fishing industries. They’re also a source of food, materials, and traditional activities for many communities.

Threats to Coral Reefs

Sadly, these precious ecosystems are under threat:

  • Climate change is increasing ocean temperatures and negatively impacting coral reef health. 
  • Increasing population density and coastal development lead to more land-based pollution and sediments being washed into the ocean.
  • Tourism and divers damage, grounding, and runoff all stress coral reefs. 
  • Overfishing and rising sea levels are additional issues contributing to their decline.

Critical planning efforts

But there’s still hope! By making critical planning efforts, we can ensure that Hawaii’s coral reefs will stay healthy for future generations:

  • Community action and awareness-raising are vital to protecting these sensitive habitats. 
  • Scientific research and management applications help us tailor our conservation strategies to the unique needs of each ecosystem.
  • On-the-ground management projects – such as monitoring water quality, removing invasive species, or restoring damaged areas – are essential to preserving this habitat.
  • Hawaiian residents and tourists should try to keep coral reefs healthy and vibrant. 

So when you next visit Hawaii and one of these stunningly beautiful places, remember to take care of it so everyone can experience its wonder.

Types of Coral

Coral is a beautiful and diverse marine life in many oceans worldwide. From stony corals to live rock coral, they come in all shapes and sizes – each unique and captivating in its distinct way. Let’s take a look at two different types of coral.

Stony Corals

Stony corals belong to the Order Scleractinia and have hard skeletons made of calcium carbonate. Each one houses tiny organisms known as zooxanthellae that give coral its vibrant colors. You can find these corals mainly in tropical waters, but they can also be found in other areas.

Rules Pertaining to Stony Corals

It’s essential to maintain healthy habitats for these amazing creatures. That’s why taking, breaking, or damaging any stony corals is unlawful. It’s also illegal to introduce sediment that could cause harm to them. 

But here’s the good news: dead stony coral may still be sold, making it an option if you’re ever looking for a souvenir from your underwater adventures.

Live Rock Coral

Live rock coral, or LR, is any natural substrate with attached marine life, including rocks, shells, and even old shipwrecks. They provide a haven for various animals, so it’s important to remember not to touch or disturb them. 

Like stony corals, taking, breaking, or damaging any live rock coral is unlawful. And don’t even think about selling it – that’s strictly forbidden!

No matter what type of coral you encounter while exploring our oceans’ depths, respecting and appreciating them is essential. After all, they’ve been around for hundreds of millions of years and are vital in keeping our planet healthy. So let’s do our part to ensure they stay protected for generations.

Rose or Cauliflower Coral (Pocillopora meandrina)

This type of coral creates spectacular cauliflower-shaped heads that measure 10-20 inches in diameter. Branches with wart-like dot projections called verrucae add texture and contrast to the overall look. Depending on the species, the color can range anywhere from brown to pink.

Lace Coral (Pocillopora damicornis)

The lace coral forms small bushy clumps that reach up to 6 inches in diameter. Its branches are thin and delicate in calm waters but robust enough to withstand wave action. Color ranges from light brown to dark brown.

Antler Coral (Pocillopora eydouxi)

These thick pipe-like branches resemble antlers, making this type of coral truly one of a kind. Verrucae are also present here. You can usually find this type of coral at 35-150 feet deep, where its brown coloration appears darker than other Pocilloporid corals.

Lobe Coral (Porites lobata)

Lobe corals come in a variety of encrusting and massive forms, ranging from intertidal zones all the way down to 180 feet. Alpheid shrimp create long narrow cracks, and calyces appear snowflake-like, shallow, and flush. Colors range from yellowish-green to brown and blue.

Finger Coral (Porites compressa)

Finger coral has finger-like branching structures covered with shallow snowflake calyxes. You can typically find this species in protected areas and deeper reef slopes at depths of 150 ft. Light brown to yellowish-green colonies is most common.

Rice Coral (Montipora capitata)

Rice coral stands out due to nipple-like projections (papillae). Calices between these papillae create a ‘rice and pepper’ appearance. It is sometimes found at depths up to 150 feet and grows in either platelike or branchlike forms. Colonies usually appear in shades of brown, while edges may be white.

Mushroom or Razor Coral (Fungia scutaria)

A solitary polyp, free-living coral, the mushroom or razor coral, looks like a disk-like elliptical shape that measures 1.5-7 inches in diameter and lives on reef flats and depths over 75 feet. They vary in color from pale brown to dark brown – dependent on the shade or water depth.

Cup or Tube Coral (Tubastraea coccinea)

Last but not least, we have cup or tube coral. This non-reef-building coral is commonly found in shallow Hawaiian waters, forming massive calyces that form 2-4 inches in diameter clumps. Bright orange, pink, or black tissue makes this species particularly eye-catching.

State of Hawaii Coral Reef Program:

The State of Hawaii Department of Land and Natural Resources (DLNR) coordinates the state’s efforts to protect coral reefs. The DLNR created the Coral Reef Working Group, consisting of various state and federal partners managing the coral reefs. These dedicated individuals are committed to preserving the delicate balance between humans and nature that makes up the Hawaiian ecosystem.

Protecting Coral Reefs and Preserving Ecosystems

When it comes to protecting coral reefs, each of us has a role. I’m sure you don’t want to do anything that would hurt these beautiful organisms, so here are some simple things you can do:

  • Avoid walking on the reef or dragging kayaks or surfboards over it, as this can cause damage to the fragile corals.
  • Don’t take or pick coral – leave them where they belong!
  • Dispose of your waste correctly – never dump fish or plants into the ocean, and always remember to keep our oceans litter-free.
  • Sterilize and clean all your diving equipment before entering the water – this helps prevent the spread of diseases and invasive species.

These small actions can make a big difference in keeping Hawaii’s coral reefs healthy and vibrant. So let’s work together to preserve this precious resource for future generations.
