Hail Mary effort aims to save the world's most endangered turtles

The Wildlife Conservation Society (WCS) has pledged to work with all of its institutions to save at least half of the world's most 25 endangered turtles as listed in a report by WCS and the Turtle Conservation Coalition last year. The program will include both conservation work in the field as well as participation from WCS's zoological institutions for captive breeding and future reintroductions. Even with WCS's ambitious program, however, it is likely this century will see a number of turtle extinctions. "Only by garnering the vast knowledge and resources from across the whole of WCS can we successfully address the threats to the world’s endangered turtles," Dr. Elizabeth Bennett, Vice President of Species Conservation at WCS said in a press release. "WCS's long history and current broad and deep expertise position us to rise to this challenge, and to conserve the threatened species across this ancient, diverse, and fascinating lineage." Although having been around for over 200 million years, turtles worldwide are currently being decimated worldwide by habitat loss and the illegal wildlife trade, largely driven by demand in East Asia where turtle parts are used for food and traditional medicine. The illegal pet trade and pollution also pose problems for turtles. Currently over half of the world's turtles (including freshwater species and tortoises) are threatened with extinction, making the group even more vulnerable than amphibians which biologists consider to be facing a mass extinction crisis of their own. The Top 25 Most Endangered Turtles list includes four species from South and Central America, three from Africa, and one from Australia, but Asia is the epicenter for turtles in trouble with 17 of the top 25 species, or 68 percent. The numbers are even more alarming if one looks only at the top ten: eight of the top ten are in Asia, and six of these reside in China. To kick-off its effort, WCS will be focusing on conservation projects for four species in the field: the Burmese starred tortoise (Geochelone platynota), the Burmese roofed turtle (Batagur trivittata), the Southern River terrapin (Batagur affinis), and the Central American river turtle (Dermatemys mawii). Meanwhile, the organization is planning captive breeding programs for other species with plans to ultimately re-introduce individuals back into their native habitat. For some turtles, however, it may be too late. Only one Abdington Island tortoise (Chelonoidis abingdonii) survives today; 'Lonesome George,' as he is known, is quite simply the last of his species. There are only two Yangtze giant softshell tortoises (Rafetus swinhoei) in captivity and two known in the wild. Researchers hope the captive pair will breed, but to date all the eggs laid have been infertile. 1. Abdington Island tortoise (Chelonoidis abingdonii) 2.
