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.

Greenpeace images show Great Barrier Reef suffering coral bleaching for second year in a row

Greenpeace Australia Pacific today releases shocking photos and footage documenting the Great Barrier Reef’s first severe coral bleaching to happen two years in a row. The bleaching is the result of 12 months of above-average sea temperatures, which is “cooking the reef alive”.

50 Reefs Initiative Is Good News For Coral Reefs

Coral reefs are in crisis. The facts are clear: without a different approach to conservation, coral reefs will continue to decline toward extinction. However, an announcement last week in Bali, Indonesia gave us some new reasons to be hopeful.

Red Sea Mangroves Fight Back in the Face of Global Decline

The Red Sea is one of the world’s saltiest and warmest seas. It is an extremely harsh environment surrounded by desert and subject to very high temperatures. However, there has been no decline in mangrove stands in the Red Sea, where the extreme conditions seem to mean that the mangroves of the Red Sea have been subjected to much lower levels of human activity than elsewhere.

Cost-effective solutions to sediment runoff and other land-based pollution affecting West Maui reefs

Land-based pollutants have been linked to the degradation of several Hawaiian reefs. Between 2000 and 2015, coral cover on West Maui’s northern reefs has dramatically declined from 30 percent to 10 percent.

The Human Element of Mangrove Management

As global climate change continues to threaten coastal communities in the tropics, discussions around mangrove forest conservation and rehabilitation have been focused primarily on ecological conditions, lacking a more robust analysis about the ways land governance, resource rights arrangements, and land use planning — the social aspects of the conservation challenge — affect mangrove conservation and rehabilitation…

Threat of poisonous algae growing on Great Barrier Reef

Japan’s Largest Coral Reef Is Dying

More than 90 percent of the corals in Sekiseishoko reef, located in the Ryukyu Islands near Okinawa, were discovered to be at least partially bleached when surveyed in November and December. About 70 percent of the reef’s living corals were found to have died.

Video Captures the Violent Act of Coral Bleaching

The video revealed for the first time how the mushroom coral Heliofungia actiniformis, which is a single polyp, physically reacts to heat stress. The results gave scientists more information about how corals will respond to warming seas that are associated with climate change.
