This past October, the community members and conservationists identified five turtle nests with about 20 eggs each and fenced them off, but they didn’t know the species of the eggs’ occupants until the babies began hatching in June. Now that they’re identified as Burmese peacock turtles, more research can begin. That the eggs incubated for nine months is already an unusual finding, Mr. Zau Lunn said. Other turtle species’ eggs, even in the Nilssonia genus, hatch after just two or three months.

“When you’re doing conservation work, you have to know something about the basic life history of the organism,” said Steven Platt, a herpetologist with the Wildlife Conservation Society, who is one of the few scientists who have researched the Burmese peacock turtle.

Just finding and describing nesting sites is valuable for science and conservation, said Dr. Platt, who isn’t involved in this project. “Those are all pieces of the puzzle that we’re slowly assembling. Unfortunately, we don’t have a lot of time, because these species are declining at such a rapid rate.”

The Indawgyi Lake turtle guardians protected these eggs, but threats to the species remain, including habitat loss, pollution, climate change, accidental catches by fishermen, and hunting for subsistence or the international wildlife trade. About 40 percent of all turtle and tortoise species are threatened, according to the International Union for Conservation of Nature’s Red List. The total number of Burmese peacock turtles is unknown, but scientists suspect that their population may have declined by at least 80 percent over the past 90 years.

While adult turtles are mostly invulnerable to predators, very few turtles survive from the egg and hatchling stages to adulthood, Dr. Platt said. That makes these Burmese peacock turtle babies all the more precious.

Dr. Janzen, from Michigan State University, applauded the turtle guardians. “This is the fruit of their labor,” he said. Local collaboration is what makes conservation efforts succeed and last, Dr. Janzen said. “If people have a stake in it, a joy, a passion, that’s going to make it sustainable.”
