After encouraging gains in the 1990s, populations of loggerhead sea turtles are now dropping, primarily because of commercial fishing, according to a US government review.
The report stops short of recommending upgrading the federally threatened species to "endangered" status. But scientists and environmentalists say it should serve as a wake-up call about the future of loggerheads, which can grow to more than 136kg and are believed to be one of the oldest species.
"We are very concerned," said Mark Dodd, a wildlife biologist for the state of Georgia.
Last year, the state counted the third lowest loggerhead nesting total since daily monitoring began in 1989.
"As a biologist you're always trying to find that point at which we really have to start doing something drastic if we want to maintain loggerhead populations on our beaches," Dodd said.
The state is not there yet, he said, but it has increased protections for the turtle under its own endangered species law.
The US southeast is one of the two largest loggerhead nesting areas in the world; eggs are laid and hatched along beaches from Texas to North Carolina. The other major nesting area is in the Middle Eastern nation of Oman.
According to the federal report, US nestings have dropped almost 7 percent annually in the Gulf of Mexico in recent years. Numbers in south Florida are down about 4 percent annually, while populations in the Carolinas and Georgia have dropped about 2 percent per year.
The review, a five-year status update required under the Endangered Species Act, compiled data from previous local reports.
