First Green Turtle Nesting on Hawaii Spotted by Park Volunteers

The Hawaii Island Hawksbill Turtle Recovery Project has recorded one of its most historic sea turtle nesting seasons in 22 years, including the first recorded green turtle nesting on the island of Hawaii.

The project also recorded a rare daytime nesting by a hawksbill turtle, and an increase in the number of newly tagged female hawksbills.

Her historic nest was a success, with 40 baby honu reaching the ocean. Green turtles are federally listed as threatened, are indigenous to Hawaii, and are seen throughout the islands. They typically nest in the French Frigate Shoals, but there have been occasional documented nestings by honu on the other main Hawaiian Islands.

Also within Hawaii Volcanoes National Park, a female honu ‘ea, or hawksbill turtle, was observed nesting at Āpua Point at noon, the earliest daytime crawl in project history. Hawksbill turtles are endangered, and nest primarily at beaches along the southern coast of Hawaii Island at night.

Volunteers helped an estimated 3,000 hatchlings reach the ocean from a total of 30 nests (one green, 29 hawksbill) along five of the beaches they monitor: Āpua Point, Halapē, Kamehame, Kōloa, and Pōhue Bay.

"Without the help from over 20 dedicated volunteers this season, many of these hatchlings would not have made it to the ocean. Thanks to them, there is hope for the survival of honu ‘ea," said Will Seitz, project coordinator.

Out of the nine female adult hawksbill turtle observed, five were newly tagged while the rest were returnees from previous seasons.

During nesting season, from May through December, females come ashore to lay clutches of eggs. The eggs are vulnerable during the two-month incubation, and are preyed upon by mongoose, rats, feral cats, and dogs.

After the hatchlings emerge they can become caught behind rocks or vegetation, disoriented by artificial lights, run over by vehicles, or eaten by mammals and birds. Volunteer efforts are critical to their survival.

Hawaii Volcanoes National Park displays the results of 70 million years of volcanism, migration, and evolution. The park highlights two of the world's most active volcanoes, and offers insights on the birth of the Hawaiian Islands and views of dramatic volcanic landscapes.

In 2011, an estimated 1,352,122 people visited Hawaii Volcanoes National Park, an increase of 3.6 percent from 2010.
