Study shows that sea turtles can recover
December 18, 2007
A team of researchers led researchers from IUCN and Conservation International found that green turtle (Chelonia mydas) nesting on four beaches in the Pacific and two beaches in the Atlantic have increased by an four to fourteen percent annually over the past two to three decades as a result of beach protection efforts.
"These results should be celebrated," said Milani Chaloupka, lead author and vice chair of the IUCN Marine Turtle Specialist Group. "They demonstrate that green turtle populations and presumably the green turtles' ecosystem roles can be recovered in spite of drastic population declines in the past."
"This analysis shines a light of hope on marine conservation efforts for endangered species and for biological diversity as a whole," said Sebastian Troëng, co-author, MTSG member, and senior director of regional marine strategies at Conservation International. "Ambitious strategies including long-term protection of habitats and reduction of survival threats are working, and endangered species can be recovered."
"In Tortuguero, the recovering green turtle population attracts millions of dollars in tourism revenue each year for the local community as tourists come to watch the turtles lay their eggs," said David Godfrey, MTSG member and executive director of the Caribbean Conservation Corporation. "Unfortunately, these same turtles are still hunted by the thousands when they swim to Nicaraguan waters in search of seagrass, so conservation efforts must continue."
