KYPARISSIA, Greece (AFP) – Freed from its eggshell by a volunteer, the tiny turtle hatchling clambers across a pebble-strewn sandy Greek beach in a race to the sea, the start of a hazardous journey that only one in 1,000 will survive.
Kira Schirrmacher, 22, donning black gloves to gently ease the newborn loggerhead turtle on its way, grins at suggestions that she’s a kind of “midwife”.
“Yes, I do that all day,” says the German social sciences student, of her role.
She’s one of several volunteers monitoring the beaches of Kyparissia Bay, the Mediterranean’s largest nesting ground for the loggerhead, whose scientific name is Caretta caretta.
Tourism, climate change and good fortune all weigh on the future of the loggerhead population, which the International Union for Conservation of Nature lists as vulnerable.
Even sun loungers on the beach that can snag the turtles and bright lights that lure the hatchlings away from the water at night are potential threats, say environmentalists.
Their overall numbers are unknown but some Pacific and Indian Ocean populations are critically low, while conservation measures have bolstered their presence in the Mediterranean, environmental groups say.
With around 44 kilometres of coastline, Kyparissia on the western Peloponnese, had over 3,700 nests this year, up from 3,500 in 2018, says the Athens-based Archelon turtle protection organisation.
“It seems (more of) our female turtles survive and come back to nest,” says oceanographer Dimitris Fytilis.
Each nest contains up to 120 eggs but up to a fifth may fail to hatch at all.
Loggerheads can live to 80 years of age, grow to more than half a metre and weigh up to 80 kilos but face mortal danger from birth.
Newborns must evade dogs, jackals, foxes, seagulls and other predators just to make it to the sea.
Once in the water, the five-centimetre turtle will swim non-stop for at least 24 hours to work its lungs and find food but is prey to crabs, fish and even adult turtles.
More than 600 turtles turn up dead in Greece every year, mostly on beaches but also in the water, trapped in nets or sick, the rescue centre says.
It has treated more than 1,100 injured turtles since it began in 1994 and receives some 70 new cases every year.
The turtles ingest fishhooks and plastic debris but more than half of their injuries are caused by humans, usually by blows to the head with oars and axes.
Fishermen are often blamed as repairing fishing nets damaged by turtles can be costly.
Climate change has also created the potential to shift the turtle gender balance, as males cannot incubate at a nest temperature above 29.3 degrees Celsius.
“There is already an effect in some countries… in Australia for example, more females are born now because of global warming,” Fytilis said.
Another key nesting ground at Laganas Bay, in Zakynthos on the Ionian island of Zante, attracts hundreds of thousands of tourists annually.
Like in other popular tourist destinations, environmental groups have for decades tussled with hotels and restaurants that chafe against protection efforts.
“We don’t really get support from the locals,” says Schirrmacher.
But one hotelier in the resort suggests the area should develop its turtle tourism.
“There should be a glass-bottomed boat for turtle watching, but the authorities here can’t even build a proper road to the beach,” he fumes.
Adding to ecologists’ concerns are moves by Greece’s new conservative government to relax environmental restrictions to promote further tourism investment.
