Feb. 26, 2013 An international team led by the University of Alabama at Birmingham (UAB) has documented a 78 percent decline in the number of nests of the critically endangered leatherback sea turtle (Dermochelys coriacea) at the turtle's last stronghold in the Pacific Ocean.
The study, published online Feb. 26 in the Ecological Society of America's scientific online journal Ecosphere, reveals leatherback nests at Jamursba Medi Beach in Papua Barat, Indonesia -- which accounts for 75 percent of the total leatherback nesting in the western Pacific -- have fallen from a peak of 14,455 in 1984 to a low of 1,532 in 2011. Less than 500 leatherbacks now nest at this site annually.
Thane Wibbels, Ph.D., a professor of reproductive biology at UAB and member of a research team that includes scientists from State University of Papua (UNIPA), the National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service and the World Wildlife Fund (WWF) Indonesia, says the largest marine turtle in the world could soon vanish.
"If the decline continues, within 20 years it will be difficult if not impossible for the leatherback to avoid extinction," said Wibbels, who has studied marine turtles since 1980. "That means the number of turtles would be so low that the species could not make a comeback.

Sad stuff.

(28 posts)Turtles are a victim of a US scheme in 1962 to mine West Papua, along with the rain forests as the Papuan people are replaced by millions (yes millions) of Indonesians. There have been 100,000's of people killed to silence their plead for freedom. People are fighting for their lives, the Papuan to live and the Indonesians to remove the Papuans; little wonder turtle eggs have joined the victims during the fifty year scheme
The US businessman Robert Lovett and his friend McGeorge Bundy tricked President Kennedy into the deal, a plan to force the Dutch to sign a UN trusteeship agreement which the public was not told was a trusteeship agreement.
Today America has its gold & copper mine and the Papuan people are being ethnically replaced by Indonesians. It is tragic that Chapter XII of the UN Charter does not force lawyers to use the word trusteeship in a trusteeship agreement, but article 85 of the UN Charter is the only way that the General Assembly in resolution 1752 (XVII) instead of the Security Council was able to direct UN forces to occupy the colony.
Little wonder France and others refused to vote and Senegal pleaded for its vote to be recorded as opposing res. 1752 (XVII) but the deal was done and for fifty years people as well as turtles have been dying
