Mangrove & Coral Destruction

Widespread destruction of mangroves (Bahamas, Australia) and Coral Reefs (Caribbean, Red Sea) has resulted in the loss of some of the worlds most diverse ecosystems. As a side effect, this has greatly increased shoreline hazards and beach erosion rates. The greatest benefit of mangroves is their ability to reduce storm surge. This benefit is long-term and requires no maintenance. The 1999 super typhoon, Orissa, killed over 10,000 people in India drowning many with its powerful storm surge. This number could have been lower if the mangroves had been retained. Mangroves are lost because of clearing for development, logging, and shrimp farming. Coral reefs are lost by mining (Bali, Indonesia), sedimentation from agriculture on the upland (St. Croix, Virgin Islands), bad fishing techniques that kill corals (Pacific Islands), sedimentation from nourished beaches (Waikiki) and a host of other natural and global warming-related causes. Dubai is perhaps the single greatest example of coral reef destruction. The artificial islands built there buried vast coral reefs. Mangroves and coral reefs often provide protection for nearby beaches. Their destruction harms the beach as well.

Worldwide Map Identifies Important Coral Reefs Exposed to Stress

The world’s coral reefs face a multitude of threats, from rising ocean temperatures to overfishing. A new map aimed at aiding coral conservation has been developed that points out the reefs that are most and least at risk.

Geographic Analysis Offers New Insight Into Coral Disease Spread

In the last 30 years, more than 90 percent of the reef-building coral responsible for maintaining major marine habitats and providing a natural barrier against hurricanes in the Caribbean has disappeared because of a disease of unknown origin.

Capt. Kidd Shipwreck Site to Be Dedicated Living Museum of the Sea

This unique museum, resting in less than 10 feet of water just 70 feet from Dominican Republic’s shoreline, will give divers the opportunity to see the 17th century ship remains, which rest on the ocean’s floor and will serve as home to sea creatures and protect precious corals and other threatened biodiversity in the surrounding reef systems.

Mangroves excel at storing climate-warming carbon

Mangroves store two to four times the carbon that tropical rainforests do. Part of the reason for mangroves’ efficiency in keeping carbon locked away lies in their location in tidal zones, where their roots are often covered with sea water.

New Caledonia’s Lagoon: Better Understanding for Better Protection

New Caledonia possesses the second largest coral reef lagoon on Earth and harbours an exceptional biodiversity. The island is also the world’s third most important nickel producer. Ore extraction over the 20th Century has in places tripled the input of sediments and accompanying pollutants, such as metals, in the marine environment.

Bioengineering Uses Vetiver Grass to Save Coral Reefs Near Guam

The vetiver grass system is a unique, economical and effective bioengineering technology for protecting coral reefs. It is also expected that these vetiver hedges may even be able to protect the beach area against tidal surge once their root systems are well established.

Last Chance Beach, Battling Erosion in Barbados

Around Barbados, the most serious threat to the beaches is the loss of coral reefs through nearshore pollution, primarily caused by domestic sewage, and physical clearing. As the reefs die, they lose their ability to reduce the energy and erosive force of incoming waves.
