Small enough to fit in the palm of your hand, newly hatched sea turtles emerged on a Gabonese beach to embark on the treacherous 10-meter (33-foot) scramble across the sand to the ocean.
"The survival rate for turtles is one in 1,000," Francois Boussamba, a Gabonese turtle expert and head of the NGO Aventures Sans Frontieres (Adventures Without Borders), told AFP, scouring for nests.
Conservationists from NGOs and the national parks agency patrol Gabon's beaches daily during the nesting season to protect the turtles' nests.
Those under threat are moved to a hatchery, a fenced enclosure near the sea, where the eggs are kept safe until they are ready to hatch.
On Pongara National Park's white sandy beaches, about 30 minutes by boat from the capital Libreville, conditions are optimal for nesting: wild coastline, a favorable equatorial climate and an open ocean beach with gentle slopes, ideal for the females.
But dangers lurk. Nests are threatened by coastal erosion due to encroaching sea levels, or myriad predators such as crabs and birds that prevent the eggs from reaching their 60-day incubation period, Boussamba said.
"The chances of survival are tiny," he said.
- Muscle up -
In Libreville, every morning around 7:00 am, volunteers from the Project Turtles Tahiti Gabon association crisscross the beach and check the nests in the hatchery.
After one has hatched, the baby turtles have to be moved so they can reach the sea -- but they are never put straight into the water.
"They need to build up their muscles so they can swim in the ocean," volunteer Clemence said.
Four species of turtles -- green, olive ridley, hawksbill and leatherback -- come to nest along Gabon's 900 kilometers (560 miles) of coastline from October to April.
It has the highest nesting density on the African continent, according to the US-based NGO Wildlife Conservation Society.
Gabon is the world's leading nesting site for the leatherback turtle, the largest of the species and listed as threatened by the International Union for Conservation of Nature (IUCN).
In addition to predators, sea turtles are also threatened by human activities, from plastic pollution to industrial fishing and poachers.
By watching over the eggs, the rangers in Pongara help ensure "the survival of this species", Edouard Moussavou, Pongara park's deputy director, said.
- Unpaid wages -
Since 2013, Gabon's conservation efforts had received funding from the United States, notably through the US Fish and Wildlife Service, an agency responsible for biodiversity.
"If there are turtles, it means our ecosystem is sound and healthy," Boussamba said.
But since the suspension of grants by the administration of US President Donald Trump, "turtle monitoring activities have stopped or slowed down drastically", Moussavou said.
"There will be fewer staff, less data, and that really creates difficulties for us," he said.
Additionally, there have been delays in paying the staff of the National Agency for National Parks (ANPN), which manages the country's 13 parks, according to Sosthene Ndong Engonga, secretary-general of the National Union of Gabonese Ecoguards.
The around 580 eco-rangers regularly go unpaid.
"Even when there is money, we have to make a big fuss to get our salaries," he said, adding he battled with the treasury last month for back pay.
The eco-rangers, who are crucial for the conservation of Gabon's biodiversity, face having "to give everything up," Engonga warned. "We have expenses we can no longer cover," he said.
On Pongara beach, 40-year-old Alain Banguiya carries out night patrols, hoping to see a leatherback turtle emerge from the water to lay her eggs in the sand.
An eco-ranger since 2015, he has not been paid for two months but says that giving up is out of the question.
"We have a duty to fight to the end, to keep our spirits up," he said. "Despite the obstacles, we stay the course: conservation."
