Just after ten o'clock on Thursday night, a drone humming low over Khao Na Yak Beach caught the unmistakable silhouette of a leatherback sea turtle climbing above the tide line. For the rangers of the Marine National Park Education and Research Center No. 2 watching the feed, the shape needed no introduction. They already knew who she was. [ref:1]
Mae Namo — “Mae” for mother, “Namo” drawn from the park she returns to, Khao Lampi–Hat Thai Mueang in Phang Nga — had come ashore for the sixth time this season. In the context of leatherback sea turtle conservation in Thailand, that number carries weight. These are ancient animals, critically endangered, whose nesting sites along the Andaman coast number in the single digits. For one female to return six times in a single season, methodically laying her clutches in the sand she has chosen, is not routine. It is, for the people who have spent years protecting that beach, a kind of reward.
The patrol team confirmed her identity through records built up over repeated encounters: the same mother, the same coast, the same unhurried process of locating her site, digging her chamber, and filling it with the next generation’s hope.
This time, she left behind 123 eggs: 107 viable, 16 infertile. Because Khao Na Yak Beach sits in a stretch prone to tidal flooding, the park staff did not leave them where she had placed them. Following established protocol, they gently excavated the clutch and relocated each egg to the hatchery near the visitor centre — a sand-floored facility designed to replicate natural incubation conditions while keeping the eggs safe from surge and predation. Round-the-clock monitoring begins the moment the eggs arrive.
The Khao Lampi–Hat Thai Mueang National Park has quietly become one of Thailand’s most important leatherback nurseries. The coastline here — a long, wild sweep of Andaman beach backed by coastal forest — was chosen by these turtles long before anyone named the park. Their seasonal rhythm runs from roughly November through June, when females heave themselves ashore in the dark, nest, and return to the sea before first light. Most people who visit this stretch of Phang Nga coast never know the nesting is happening at all. That is, in part, by design: rangers now patrol at night using drones rather than torchlit walks that once risked startling nesting turtles mid-dig. [ref:2]
Mae Namo is not the only leatherback known to this beach, but she is among the most documented. Her earlier nests this season — spread across weeks of dark-moon nights — have each added to a ledger the park has been keeping for years. Each nest is GPS-tagged, each clutch catalogued, each hatchling counted when they finally orient themselves toward the Andaman and enter it for the first time.
Leatherbacks are the largest sea turtles on Earth, sometimes reaching 600 kilograms, and they navigate the Pacific and Indian Oceans across distances that dwarf any map. What draws a female to return to the same stretch of Phang Nga sand, season after season, is a mystery science has only begun to unpack. Researchers believe each female imprints on her birth beach, carrying its chemical signature through decades of ocean wandering until she is ready to nest herself. Mae Namo, in other words, may have hatched on Khao Na Yak Beach — and has simply never stopped coming home. [ref:1]
For the communities of Hat Thai Mueang district, the turtle season is familiar. Local fishing families know the stretch of coast where the lights stay off at night and the rangers’ boats idle in the shallows. Older residents can remember decades when leatherback nests were fewer, seasons when no one came, stretches when the hatching sand ran empty. The return — not just of Mae Namo but of the conservation culture that protects her — represents something the district has worked toward for a long time.
The eggs laid on June 19 will incubate for approximately 65 days in the park’s hatchery. If conditions hold, the next generation of hatchlings from this particular clutch may emerge sometime in late August, tiny and purposeful, tumbling toward a sea that will carry them for the rest of their lives.
Mae Namo, meanwhile, will rest in the Andaman and, in some weeks, return again. The rangers will be watching. [ref:1]
