Loggerhead sea turtle nesting activity on Boa Vista island increased 80-fold between 1998 and 2024

In 1998, a few volunteers walked the dark beaches of a tiny Atlantic island… counting turtle nests by torchlight.

They barely found any.

Fast forward to 2024.

The same beaches are teeming.

Thousands of turtles. Thousands of nests. A coastline that looks like it's breathing.

🐢 Loggerhead nesting on Boa Vista has jumped 80-fold in 27 years.

Let that sink in.

Not 80%. Eighty times more.


🌙 The night the patrols knew something had changed

For years, volunteers expected the usual: 5 to 10 nesting females per shift.

Then around 2018, the numbers got weird.

  • 🐾 20 to 30 turtles a night
  • 🔥 By 2021, some patrols counted 30 to 40 females in a single shift
  • 📈 One season alone logged over 19,000 nests on protected stretches

The data caught up later. The turtles got there first.


🌊 Boa Vista just joined the world's elite

Florida. Oman. The legendary loggerhead capitals.

Their peak density? Around 965 nests per mile.

Boa Vista's top three beaches in 2021?

Over 35,000 nests per mile. 🤯

A dot in the Atlantic is now arguably the most important loggerhead rookery on Earth.


🧠 The twist nobody talks about

Sea turtles don't bounce back fast.

They live for decades. They roam entire oceans. Females only return to nest after 20–30 years.

So the turtles laying eggs today?

They were hatchlings protected by volunteers in the late 90s and early 2000s.

This isn't a quick win.

It's a generational love letter, finally answered.


⚔️ How they actually pulled it off

No silver bullet. Just stubborn, layered work:

  • 🏝️ Protecting nesting beaches
  • 🚫 Cracking down on poaching
  • 🥚 Relocating nests from floods and predators
  • 👨‍👩‍👧 Turning locals — most of Cabo Verde Natura 2000's team is Cape Verdean — into the frontline
  • 💸 Building ecotourism so a living turtle was worth more than a dead one

⚡ But success has a strange shadow

Too many turtles, too little beach.

Females now dig up each other's nests by accident. Storms can wipe out thousands of eggs in one hit. The species is still Vulnerable on the IUCN Red List — global populations are down roughly 47% over three generations.

And while Cabo Verde dances on the world football stage, a quieter miracle is unfolding on its sand.

Proof that patience, when it's stubborn enough, beats extinction.

That's all for now!
