The United States issued a ruling on Friday saying that five world populations of loggerhead sea turtles are endangered species but four are only "threatened."
The decision to split up loggerhead turtles into nine separate populations for conservation efforts was detailed in a 331-page document by the US Fish and Wildlife Service and the National Oceanic and Atmospheric Administration.
"This division... will help us focus more on the individual threats turtles face in different areas," said Jim Lecky, NOAA Fisheries director of protected resources.
"Wide-ranging species, such as the loggerhead, benefit from assessing and addressing threats on a regional scale."
However, Oceana, a leading conservation group which had pressed for more protections for sea turtles, described the move as "bittersweet."
"Sea turtles are disappearing right before this generation's eyes," said Whit Sheard, Pacific counsel and senior adviser for Oceana.
"While today's designation gives new hope for North Pacific loggerheads, it leaves the fate of the species in the Atlantic at risk."
Two turtle populations -- those in the Southeast Indo-Pacific Ocean and Northwest Atlantic Ocean -- were changed from endangered to threatened because their nesting areas are in protected lands and their numbers are stabilizing.
Improvements to fishing nets, which now include turtle excluder devices in shrimp trawlers allowing turtles to escape, have also helped save turtle populations.
The five that retained their endangered status were in the Northeast Atlantic Ocean, Mediterranean Sea, North Indian Ocean, North Pacific Ocean and South Pacific.
Oceana and the Center for Biological Diversity were among the environmental groups that petitioned in 2007 for loggerhead sea turtles in the North Pacific and Northwest Atlantic to be reclassified as endangered.
"Loggerheads have declined by at least 80 percent in the North Pacific and could become functionally or ecologically extinct by the mid-21st century if additional protections are not put into place," said a statement by Oceana.
"Florida beaches, which host the largest nesting population of loggerheads in the Northwest Atlantic, have seen more than a 25 percent decline in nesting since 1998."
Earlier this week, a study in the US journal Biological Conservation said that improved fishing nets have saved tens of thousands of endangered sea turtles in recent years, but 4,600 are still dying annually, mainly in Gulf of Mexico shrimp trawls.

Sea level rise may take economic toll on California coast
San Francisco CA (SPX) Sep 15, 2011
California beach towns could face hefty economic losses caused by sea level rise in the next century, according to a new state-commissioned study conducted by economists at San Francisco State University. The study forecasts the economic impact of sea level rise on five communities: Ocean Beach in San Francisco; Venice Beach and Malibu in Los Angeles; Carpinteria in Santa Barbara County; and Tor ... read more
