Guam's Diverse Coral Reefs Bleached In 2016 For Fourth Straight Year
EDIT
But while the devastation is apparent in reefs all around the globe, some have received more notice than others. Australia’s Great Barrier Reef, for instance, made headlines back in April when scientists announced that a whopping 93 percent of its corals had bleached. Corals in U.S. waters, as well as other reefs scattered throughout the Pacific, have turned heads recently as well. But the plight of the corals surrounding Guam and its neighbors has largely gone unreported in mainstream media.
Nevertheless, the region is a big area of concern for marine biologists — and has been for going on four years. According to coral ecologist Laurie Raymundo of the University of Guam, the island of Guam is located just outside of the “coral triangle” — a kind of coral hotspot including the Philippines, Papua New Guinea, Malaysia, Indonesia, Timor-Leste and the Solomon Islands. It’s known for having the most diverse coral ecosystems in the world.
“Guam is right outside that ring of highest diversity, so the diversity is generally fairly high,” Raymundo said, adding that the area is believed to be home to more than 300 species of coral. Prior to 2013, she said, the corals there had not experienced much of a problem with bleaching like reefs in other parts of the world had.
“But in 2013, 2014 and 2015, we have gotten hammered,” she said. “And we’re getting hammered again. For the past four years we’ve had bleaching episodes, and we have not had them to this extent in recent history.” According to Raymundo, recent analyses have suggested that more than 50 percent of the corals there died between 2013 and 2014, and about 85 percent in total had bleached. Those estimates were made in 2015, so Raymundo estimated more corals may have died in the meantime.
