New research suggests that all seven sea turtle species are experiencing population growth worldwide, demonstrating the ecological value of long-term conservation policy and action. Sea turtle populations are often assessed at the regional to sub-basin scale from discrete indices of nesting abundance. Browse our extensive collection of zoological career infobooks including animal training, animal rescue and rehabilitation and zoo careers. Raine Island, on Australia’s Great Barrier Reef, has the second largest nesting population of about 18,000 females per season. 2007 Endangered Species Act (ESA) Five-Year Review.

Only Florida and Oman have nesting loggerhead populations of greater than 10,000; with about 20,000 nesting females in Florida and 13,000 in Oman. Population data are usually based on the numbers of adult females that come ashore to nest. The major loggerhead nesting grounds are in Oman, Australia, and the southeastern U.S., particularly in southern Florida. Even then, the numbers are ambiguous because some females nest every two to three years; some may nest more than once on the same beach in a season; and some visit more than one nesting beach in a season.
