Australia’s Great Barrier Reef, UNESCO World Heritage Site

There has been much news about the stress and difficulties experienced by Australia’s Great Barrier Reef, the largest of our planet’s coral reefs.   The Government of Australia produced in September of 2016 its Reef 2050 Long-Term Sustainability Plan.  “The plan responds to the challenges facing the Reef and presents actions to protect its values, health and resilience while allowing ecologically sustainable use,” the government’s website states.

The Great Barrier Reef is one of the United Nations Education, Scientific, and Cultural Organization’s (UNESCO) World Heritage Sites.  UNESCO seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world considered to be of outstanding value to humanity.

UNESCO has been monitoring the environmental situation with regard to the Great Barrier Reef, and has posted reports on the coral reef.  The last UNESCO monitoring mission was in 2012.

John Turner, Ph.D has been collecting fecal samples from the parrotfish to study stress in this species of reef fish, and thus to determine whether the entire reef is experiencing stress.  This photo of a Queen Parrotfish was taken among the coral reefs in the U.S. Virgin Islands.

The Invasive Lionfish: “Darwin’s Nightmare” – and the Robot

Lionfish, a beautiful exotic species from the Indo-Pacific region, began appearing in the Atlantic Ocean in the 1980s, possibly due to pet owners releasing them into waters. Since then the Lionfish have multiplied massively, eating smaller fish and out-competing fish like Grouper for food. Meanwhile they have no predators, giving them the moniker “Darwin’s Nightmare.” A group of people have developed a robot that will electrocute and collect the Lionfish.  >>> Article from PBS Newshour

 

Fish Urine Helps Coral Reefs

Fish urine contains phosphorous, which coral reefs need.  Fish also excrete ammonium through their gills which is an essential nutrient for coral reefs. So the decline of fish populations due to over-fishing can present a problem. >>> Article
